+Annulment of a check-in
+-----------------------
+
+.. http:post:: /api/v1/organizers/(organizer)/checkinrpc/annul/
+
+   If a check-in was made in error and the person was not let in, it can be annulled. We do not recommend this to be used
+   in case of manual check-ins or user interfaces because it is too prone for human errors. It is mostly intended for
+   automated entry systems like a turnstile or automated door, where the check-in is first created, then the door is
+   opened, and then the check-in may be annulled if the system knows that the turnstile did not turn or was out of
+   order.
+
+   This endpoint supports passing multiple check-in lists for the context of a multi-event scan. However, each
+   check-in list passed needs to be from a distinct event.
+
+   Check-ins created by a device can only be annulled by the same device. The datetime of annulment may not be more than
+   15 minutes after the datetime of check-in (value subject to change).
+
+   A status code of 404 is returned if no check-in was found for the given nonce. A status code of 400 is returned when
+   multiple check-ins match the nonce, the input is invalid in another way, the annulment is made from the wrong device,
+   the check-in is already in an annulled or failed state, or the datetime constraint is not valid.
+
+   :<json string nonce: ``nonce`` value of the original check-in.
+   :<json array lists: List of check-in list IDs to search on. No two check-in lists may be from the same event.
+   :<json datetime datetime: Specifies the client-side datetime of the annulment. If not supplied, the current time will be used.

+Transmission types
+------------------
+
+pretix supports multiple ways to transmit an invoice from the organizer to the invoice recipient.
+For each transmission type, different fields are supported in the ``transmission_info`` object of the
+invoice address. Currently, pretix supports the following transmission types:
+
+Email
+"""""
+
+The identifier ``"email"`` represents the transmission of PDF invoices through email.
+This is the default transmission type in pretix and has some special behavior for backwards compatibility.
+Transmission is always executed through the provider ``"email_pdf"``.
+The ``transmission_info`` object may contain the following properties:

+
+   With this API call, you can instruct the system to create a new batch.
+
+   Since batches can contain up to 10,000 tickets, they are created asynchronously on the server.
+   If your input parameters validate correctly, a ``202 Accepted`` status code is returned.
+   The body points you to the check URL of the result. Running a ``GET`` request on that result URL will
+   yield one of the following status codes:
+
+    * ``200 OK`` – The creation of the batch has succeeded. The body will be your resulting batch with the same information as in the detail endpoint above.
+    * ``409 Conflict`` – Your creation job is still running. The body will be JSON with the structure ``{"status": "running"}``. ``status`` can be ``waiting`` before the task is actually being processed. Please retry, but wait at least one second before you do.
+    * ``410 Gone`` – Creating the batch has failed permanently (e.g. quota no longer available). The body will be JSON with the structure ``{"status": "failed", "message": "Error message"}``
+    * ``404 Not Found`` – The job does not exist / is expired.
+
+   .. note:: To avoid performance issues, a maximum amount of 10000 is currently allowed.
+
+   .. note:: Do not wait multiple hours or more to retrieve your result. After a longer wait time, ``409`` might be returned permanently due to technical constraints, even though nothing will happen any more.

+   If your input parameters validate correctly, a ``202 Accepted`` status code is returned.
+   The body points you to the download URL of the result. Running a ``GET`` request on that result URL will
+   yield one of the following status codes:
+
+    * ``200 OK`` – The creation of the batch has succeeded. The body will be your resulting batch with the same information as in the detail endpoint above.
+    * ``409 Conflict`` – Your rendering process is still running. The body will be JSON with the structure ``{"status": "running"}``. ``status`` can be ``waiting`` before the task is actually being processed. Please retry, but wait at least one second before you do.
+    * ``410 Gone`` – Rendering the batch has failed permanently. The body will be JSON with the structure ``{"status": "failed", "message": "Error message"}``
+    * ``404 Not Found`` – The rendering job does not exist / is expired.

+Transactions
+============
+
+Transactions are an additional way to think about orders. They are are an immutable, filterable view into an order's
+history and are a good basis for financial reporting.
+
+Our financial model
+-------------------
+
+You can think of a pretix order similar to a debtor account in double-entry bookkeeping. For example, the flow of an
+order could look like this:
+
+===================================================== ==================== =====================
+Transaction                                           Debit                Credit
+===================================================== ==================== =====================
+Order is placed with two tickets                      € 500
+Order is paid partially with a gift card                                   € 200
+Remainder is paid with a credit card                                       € 300
+One of the tickets is canceled                        **-** € 250
+Refund is made to the credit card                                          **-** € 250
+**Balance**                                           **€ 250**            **€ 250**
+===================================================== ==================== =====================
+
+If an order is fully settled, the sums of both columns match. However, as the movements in both columns do not always
+happen at the same time, at some times during the lifecycle of an order the sums are not balanced, in which case we
+consider an order to be "pending payment" or "overpaid".
+
+In the API, the "Debit" column is represented by the "transaction" resource listed on this page.
+In many cases, the left column *usually* also matches the data returned by the :ref:`rest-invoices` resource, but there
+are two important differences:
+
+- pretix may be configured such that an invoice is not always generated for an order. In this case, only the transactions
+  return the full data set.
+
+- pretix does not enforce a new invoice to be created e.g. when a ticket is changed to a different subevent. However,
+  pretix always creates a new transaction whenever there is a change to a ticket that concerns the **price**, **tax rate**,
+  **product**, or **date** (in an event series).
+
+The :ref:`rest-orders` themselves are not a good representation of the "Debit" side of the table for accounting
+purposes since they are not immutable:
+They will only tell you the current state of the order, not what it was a week ago.
+
+The "Credit" column is represented by the :ref:`order-payment-resource` and :ref:`order-refund-resource`.

+Data sync providers
+===================
+
+.. warning:: This feature is considered **experimental**. It might change at any time without prior notice.
+
+pretix provides connectivity to many external services through plugins. A common requirement
+is unidirectionally sending (order, customer, ticket, ...) data into external systems.
+The transfer is usually triggered by signals provided by pretix core (e.g. :data:`order_placed`),
+but performed asynchronously.
+
+Such plugins should use the :class:`OutboundSyncProvider` API to utilize the queueing, retry and mapping 
+mechanisms as well as the user interface for configuration and monitoring. Sync providers are registered 
+in the :py:attr:`pretix.base.datasync.datasync.datasync_providers` :ref:`registry <registries>`.
+
+An :class:`OutboundSyncProvider` for subscribing event participants to a mailing list could start
+like this, for example:
+
+.. code-block:: python
+
+    from pretix.base.datasync.datasync import (OutboundSyncProvider, datasync_providers)
+
+    @datasync_providers.register
+    class MyListSyncProvider(OutboundSyncProvider):
+        identifier = "my_list"
+        display_name = "My Mailing List Service"
+        # ...
+
+
+The plugin must register listeners in `signals.py` for all signals that should to trigger a sync and
+within it has to call :meth:`MyListSyncProvider.enqueue_order` to enqueue the order for synchronization:
+
+.. code-block:: python
+
+    @receiver(order_placed, dispatch_uid="mylist_order_placed")
+    def on_order_placed(sender, order, **kwargs):
+        MyListSyncProvider.enqueue_order(order, "order_placed")
+
+
+Property mappings
+-----------------
+
+Most of these plugins need to translate data from some pretix objects (e.g. orders)
+into an external system's data structures. Sometimes, there is only one reasonable way or the
+plugin author makes an opinionated decision what information from which objects should be
+transferred into which data structures in the external system.
+
+Otherwise, you can use a :class:`PropertyMappingFormSet` to let the user set up a mapping from pretix model fields
+to external data fields. You could store the mapping information either in the event settings, or in a separate
+data model. Your implementation of :attr:`OutboundSyncProvider.mappings`
+needs to provide a list of mappings, which can be e.g. static objects or model instances, as long as they
+have at least the properties defined in
+:class:`pretix.base.datasync.datasync.StaticMapping`.
+
+.. code-block:: python
+
+    # class MyListSyncProvider, contd.
+        def mappings(self):
+            return [
+                StaticMapping(
+                    id=1, pretix_model='Order', external_object_type='Contact',
+                    pretix_id_field='email', external_id_field='email',
+                    property_mappings=self.event.settings.mylist_order_mapping,
+                ))
+            ]
+
+
+Currently, we support `orders` and `order positions` as data sources, with the data fields defined in
+:func:`pretix.base.datasync.sourcefields.get_data_fields`.
+
+To perform the actual sync, implement :func:`sync_object_with_properties` and optionally
+:func:`finalize_sync_order`. The former is called for each object to be created according to the ``mappings``.
+For each order that was enqueued using :func:`enqueue_order`:
+
+- each Mapping with ``pretix_model == "Order"`` results in one call to :func:`sync_object_with_properties`,
+- each Mapping with ``pretix_model == "OrderPosition"`` results in one call to
+  :func:`sync_object_with_properties` per order position,
+- :func:`finalize_sync_order` is called one time after all calls to :func:`sync_object_with_properties`.
+
+
+Implementation examples
+-----------------------
+
+For example implementations, see the test cases in :mod:`tests.base.test_datasync`.
+
+In :class:`SimpleOrderSync`, a basic data transfer of order data only is
+shown. Therein, a ``sync_object_with_properties`` method is defined as follows:
+
+.. code-block:: python
+
+    from pretix.base.datasync.utils import assign_properties
+
+    # class MyListSyncProvider, contd.
+    def sync_object_with_properties(
+            self, external_id_field, id_value, properties: list, inputs: dict,
+            mapping, mapped_objects: dict, **kwargs,
+    ):
+        # First, we query the external service if our object-to-sync already exists there.
+        # This is necessary to make sure our method is idempotent, i.e. handles already synced
+        # data gracefully.
+        pre_existing_object = self.fake_api_client.retrieve_object(
+            mapping.external_object_type,
+            external_id_field,
+            id_value
+        )
+
+        # We use the helper function ``assign_properties`` to update a pre-existing object.
+        update_values = assign_properties(
+            new_values=properties,
+            old_values=pre_existing_object or {},
+            is_new=pre_existing_object is None,
+            list_sep=";",
+        )
+
+        # Then we can send our new data to the external service. The specifics of course depends
+        # on your API, e.g. you may need to use different endpoints for creating or updating an
+        # object, or pass the identifier separately instead of in the same dictionary as the
+        # other properties.
+        result = self.fake_api_client.create_or_update_object(mapping.external_object_type, {
+            **update_values,
+            external_id_field: id_value,
+            "_id": pre_existing_object and pre_existing_object.get("_id"),
+        })
+
+        # Finally, return a dictionary containing at least `object_type`, `external_id_field`,
+        # `id_value`, `external_link_href`, and `external_link_display_name` keys.
+        # Further keys may be provided for your internal use. This dictionary is provided
+        # in following calls in the ``mapped_objects`` dict, to allow creating associations
+        # to this object.
+        return {
+            "object_type": mapping.external_object_type,
+            "external_id_field": external_id_field,

+            "external_link_href": f"https://example.org/external-system/{mapping.external_object_type}/{id_value}/",
+            "external_link_display_name": f"Contact #{id_value} - Jane Doe",
+            "my_result": result,
+        }
+
+.. note:: The result dictionaries of earlier invocations of :func:`sync_object_with_properties` are
+          only provided in subsequent calls of the same sync run, such that a mapping can
+          refer to e.g. the external id of an object created by a preceding mapping.
+          However, the result dictionaries are currently not provided across runs. This will
+          likely change in a future revision of this API, to allow easier integration of external
+          systems that do not allow retrieving/updating data by a pretix-provided key.
+
+``mapped_objects`` is a dictionary of lists of dictionaries. The keys to the dictionary are
+the mapping identifiers (``mapping.id``), the lists contain the result dictionaries returned
+by :func:`sync_object_with_properties`.
+
+
+In :class:`OrderAndTicketAssociationSync`, an example is given where orders, order positions,
+and the association between them are transferred.

+on their format.

+            "pretix_field": "email",
+            "external_field": "orderemail",

+            "pretix_field": "order_status",
+            "external_field": "status",
+            "value_map": "{\"n\": \"pending\", \"p\": \"paid\", \"e\": \"expired\", \"c\": \"canceled\", \"r\": \"refunded\"}",

+        }
+      ]
+
+
+Translating mappings on Event copy
+----------------------------------
+
+Property mappings can contain references to event-specific primary keys. Therefore, plugins must register to the
+event_copy_data signal and call translate_property_mappings on all property mappings they store.

+There are pre-defined types of invoice transmission in pretix, currently ``"email"``, ``"peppol"``, and ``"it_sdi"``.
+You can find more information about them at :ref:`rest-transmission-types`.
+
+New transmission types can not be added by plugins but need to be added to pretix itself.
+However, plugins can provide implementations for the actual transmission.
+Please read :ref:`Creating a plugin <pluginsetup>` first, if you haven't already.

-Porting a payment provider from pretix 1.x to pretix 2.x
-========================================================
-
-In pretix 2.x, we changed large parts of the payment provider API. This documentation details the changes we made
-and shows you how you can make an existing pretix 1.x payment provider compatible with pretix 2.x
-
-Conceptual overview
--------------------
-
-In pretix 1.x, an order was always directly connected to a payment provider for the full life of an order. As long as
-an order was unpaid, this could still be changed in some cases, but once an order was paid, no changes to the payment
-provider were possible any more. Additionally, the internal state of orders allowed orders only to be fully paid or
-not paid at all. This leads to a couple of consequences:
-
-* Payment-related functions (like "execute payment" or "do a refund") always operated on full orders.
-
-* Changing the total of an order was basically impossible once an order was paid, since there was no concept of
-  partial payments or partial refunds.
-
-* Payment provider plugins needed to take complicated steps to detect cases that require human intervention, like e.g.
-
-  * An order has expired, no quota is left to revive it, but a payment has been received
-
-  * A payment has been received for a canceled order
-
-  * A payment has been received for an order that has already been paid with a different payment method
-
-  * An external payment service notified us of a refund/dispute
-
-  We noticed that we copied and repeated large portions of code in all our official payment provider plugins, just
-  to deal with some of these cases.
-
-* Sometimes, there is the need to mark an order as refunded within pretix, without automatically triggering a refund
-  with an external API. Every payment method needed to implement a user interface for this independently.
-
-* If a refund was not possible automatically, there was no way user to track which payments actually have been refunded
-  manually and which are still left to do.
-
-* When the payment with one payment provider failed and the user changed to a different payment provider, all
-  information about the first payment was lost from the order object and could only be retrieved from order log data,
-  which also made it hard to design a data shredder API to get rid of this data.
-
-In pretix 2.x, we introduced two new models, :py:class:`OrderPayment <pretix.base.models.OrderPayment>` and
-:py:class:`OrderRefund <pretix.base.models.OrderRefund>`. Each instance of these is connected to an order and
-represents one single attempt to pay or refund a specific amount of money. Each one of these has an individual state,
-can individually fail or succeed, and carries an amount variable that can differ from the order total.
-
-This has the following advantages:
-
-* The system can now detect orders that are over- or underpaid, independent of the payment providers in use.
-
-* Therefore, we can now allow partial payments, partial refunds, and changing paid orders, and automatically detect
-  the cases listed above and notify the user.
-
-Payment providers now interact with those payment and refund objects more than with orders.
-
-Your to-do list
----------------
-
-Payment processing
-""""""""""""""""""
-
-* The method ``BasePaymentProvider.order_pending_render`` has been removed and replaced by a new
-  ``BasePaymentProvider.payment_pending_render(request, payment)`` method that is passed an ``OrderPayment``
-  object instead of an ``Order``.
-
-* The method ``BasePaymentProvider.payment_form_render`` now receives a new ``total`` parameter.
-
-* The method ``BasePaymentProvider.payment_perform`` has been removed and replaced by a new method
-  ``BasePaymentProvider.execute_payment(request, payment)`` that is passed an ``OrderPayment``
-  object instead of an ``Order``.
-
-* The function ``pretix.base.services.mark_order_paid`` has been removed, instead call ``payment.confirm()``
-  on a pending ``OrderPayment`` object. If no further payments are required for this order, this will also
-  mark the order as paid automatically. Note that ``payment.confirm()`` can still throw a ``QuotaExceededException``,
-  however it will still mark the payment as complete (not the order!), so you should catch this exception and
-  inform the user, but not abort the transaction.
-
-* A new property ``BasePaymentProvider.abort_pending_allowed`` has been introduced. Only if set, the user will
-  be able to retry a payment or switch the payment method when the order currently has a payment object in
-  state ``"pending"``. This replaces ``BasePaymentProvider.order_can_retry``, which no longer exists.
-
-* The methods ``BasePaymentProvider.retry_prepare`` and ``BasePaymentProvider.order_prepare`` have both been
-  replaced by a new method ``BasePaymentProvider.payment_prepare(request, payment)`` that is passed an ``OrderPayment``
-  object instead of an ``Order``. **Keep in mind that this payment object might have an amount property that
-  differs from the order total, if the order is already partially paid.**
-
-* The method ``BasePaymentProvider.order_paid_render`` has been removed.
-
-* The method ``BasePaymentProvider.order_control_render`` has been removed and replaced by a new method
-  ``BasePaymentProvider.payment_control_render(request, payment)`` that is passed an ``OrderPayment``
-  object instead of an ``Order``.
-
-* There's no need to manually deal with excess payments or duplicate payments anymore, just setting the ``OrderPayment``
-  methods to the correct state will do the job.
-
-Creating refunds
-""""""""""""""""
-
-* The methods ``BasePaymentProvider.order_control_refund_render`` and ``BasePaymentProvider.order_control_refund_perform``
-  have been removed.
-
-* Two new boolean methods ``BasePaymentProvider.payment_refund_supported(payment)`` and ``BasePaymentProvider.payment_partial_refund_supported(payment)``
-  have been introduced. They should be set to return ``True`` if and only if the payment API allows to *automatically*
-  transfer the money back to the customer.
-
-* A new method ``BasePaymentProvider.execute_refund(refund)`` has been introduced. This method is called using a
-  ``OrderRefund`` object in ``"created"`` state and is expected to transfer the money back and confirm success with
-  calling ``refund.done()``. This will only ever be called if either ``BasePaymentProvider.payment_refund_supported(payment)``
-  or ``BasePaymentProvider.payment_partial_refund_supported(payment)`` return ``True``.
-
-Processing external refunds
-"""""""""""""""""""""""""""
-
-* If e.g. a webhook API notifies you that a payment has been disputed or refunded with the external API, you are
-  expected to call ``OrderPayment.create_external_refund(self, amount, execution_date, info='{}')`` on this payment.
-  This will create and return an appropriate ``OrderRefund`` object and send out a notification. However, it will not
-  mark the order as refunded, but will ask the event organizer for a decision.
-
-Data shredders
-""""""""""""""
-
-* The method ``BasePaymentProvider.shred_payment_info`` is no longer passed an order, but instead **either**
-  an ``OrderPayment`` **or** an ``OrderRefund``.

-License FAQ
-===========
-
-.. warning::
-
-   This FAQ tries to explain in simpler terms what the license of the pretix open source project does and does not
-   allow. It is based on our interpretation of the license and is not legal advice. The contents of this page are not
-   legally binding, only the original text of the license in the `license file`_ is legally binding.
-
-How is pretix licensed?
------------------------
-
-pretix follows the popular dual licensing model. It is available under the `GNU Affero General Public License 3`_ (AGPL)
-plus some additional terms, as well as under a proprietary license ("pretix Enterprise license") on request.
-
-How can it be AGPL if there are additional terms?
--------------------------------------------------
-
-Even though it is fairly unknown, the AGPL's section 7 is titled "Additional Terms" and outlines specific conditions
-under which additional terms can be imposed on an AGPL-licensed work. In our case, we add three additional terms.
-
-The first additional term for pretix is an additional **permission**. It allows you to do something that the AGPL would
-generally not allow. As it doesn't restrict your freedoms granted by AGPL, if you don't like it, you can ignore it, and
-if you distribute pretix further, you can remove it.
-
-The second and third additional term for pretix are additional terms that restrict or specify other provisions of the
-license. AGPL specifically requires that these terms can only restrict or specify very specific things and we believe
-our additional terms are in compliance with that and are thus valid and may not be removed.
-
-Why did you choose this license model?
---------------------------------------
-
-pretix was born in the open source community and we're deeply committed to building the best open source ticketing
-solution in the world. It is important to us that pretix is available with a comprehensive feature set under term that
-are compatible with the `Open Source Definition`_. This enables event organizers from all industries and regions
-to have access to a self-hosted, privacy-friendly and secure option to host their events.
-
-However, developing and maintaining pretix is a lot of work. Between 2014 and 2021, we've received external
-contributions from more than 150 individuals. Not counting translations over 90 % of the development was
-done by staff engineers of rami.io GmbH, the company that started pretix. While we're very happy to receive many more
-contributions in the future, we also want to ensure that we continue to be able to pay people working on pretix
-full-time.
-
-We believe our model creates a good balance between ensuring pretix is available freely as well as protecting our
-business interests. Unlike licenses chosen by other projects recently, such as the Server-Side Public License, our
-choice does not restrict using pretix for any possible use case, it just sets a few rules that you have to play by
-if you do.
-
-What do I need to do if I use pretix unmodified?
-------------------------------------------------
-
-If you use pretix without any modifications or plugins, you can use it for whatever you want, as long as you keep
-all copyright notices (including the link to pretix at the bottom of the site) intact.
-
-You are also allowed to make copies of the unmodified source code and distribute them to others as long as you keep
-all copyright and license information intact.
-
-If you install **plugins**, you must follow the same terms as when using a **modified** version (see below).
-
-What do I need to do if I modify pretix?
-----------------------------------------
-
-If you want to modify pretix, you have the right to do so. However, you need to follow the following rules:
-
-* If you **run it for your own events** (events run by you or your company as well as companies from the same
-  corporate groups) our additional permission allows you to do so **without needing to share your source code
-  modifications** as long as you keep the link to pretix at the bottom of the site intact.
-
-* If you **run it for others**, for example as part of a Software-as-a-Service offering or a managed hosting service
-  you **must** make the source code **including all your modifications and all installed plugins** available under the
-  same license as pretix to every visitor of your site. You need to do so in a prominent place such as a link at the bottom of the
-  site. You also **must** keep the existing link intact.
-  You **may not** add additional restrictions on the result as a whole. You **may** add additional permissions, but
-  only on the parts you added. You **must** make clear which changes you made and you must not give the impression that
-  your modified version is an official version of pretix.
-
-* If you **distribute** the modified version, for example as a source code or software package, you **must** license it
-  under the AGPL license with the same additional terms. You **may not** add additional restrictions on the result as a
-  whole. You **may** add additional permissions, but only on the parts you added. You **must** make clear which changes
-  you made and you must not give the impression that your modified version is an official version of pretix.
-
-Does the AGPL copyleft mechanism extend to plugins?
----------------------------------------------------
-
-Yes. pretix plugins are tightly integrated with pretix, so when running pretix together with a plugin in the same
-environment they form a `combined work`_ and the copyleft mechanism of AGPL applies.
-
-Can I create proprietary or secret plugins?
--------------------------------------------
-
-Yes, you can create a proprietary or secret plugin, but it may only ever be **used** in an environment that is covered
-by the additional permission from our license. As soon as the plugin is installed in an installation that is not covered
-by our additional permission (e.g. when it is used in a SaaS environment) or covered by an active pretix Enterprise
-license it **must** be released to the visitors of the site under the same license as pretix (like a modified version
-of pretix).
-
-What licenses can plugins use?
-------------------------------
-
-Technically, you can distribute a plugin under any free or proprietary license as long as it is distributed separately.
-However, once it is either **distributed together with pretix or used in an environment not covered by our
-additional permission** or an active pretix Enterprise license, you **must** release it to all recipients of the
-distribution or all visitors of your site under the same license as pretix (like a modified version of pretix).
-
-If you release a plugin publicly, it is therefore most practical to use a license that is `compatible to AGPL`_.
-This includes most open source licenses such as AGPL, GPL, Apache, 3-clause BSD or MIT.
-
-Note however that when you license a plugin with pure AGPL, it will be incompatible with our additional permission.
-Therefore, if you want to use an AGPL-licensed plugin, you'll need to publish the source code of **all** your plugins
-under AGPL terms **even if you only use it for your own events**. A plugin would add its `own additional permission`_
-to its license to allow combining it with pretix for this use case.
-
-To make things less complicated, if you want to distribute a plugin freely, we therefore recommend distributing the
-plugin under **Apache License 2.0**, like we do for most plugins we distribute as open source.
-
-What do I need to do if I want to contribute my changes back?
--------------------------------------------------------------
-
-In order to retain the possibility for us to offer pretix in a dual licensing model, we unfortunately need you to sign
-a Contributor License Agreement (CLA) that gives us permission to use your contribution in all present and future
-distributions of pretix. We know the bureaucracy sucks. Sorry.
-
-What if I want to re-use a minor part of pretix in my project?
---------------------------------------------------------------
-
-This is the main part we dislike about AGPL: If you see a specific thing in pretix that you'd like to use in another
-project, you'll need to distribute your other project under AGPL terms as well which is often not practical.
-
-In this case, feel free to get in touch with us! We're happy to grant you special permission or pull the component
-out into a separately, permissively licensed repository. We already did that with `django-hierarkey`_ and
-`django-i18nfield`_ which have previously been parts of pretix.
-
-What can I use the name "pretix" for?
--------------------------------------
-
-The name pretix is a registered trademark by rami.io GmbH.
-
-* You **may** use it to **indicate copyright**, such as in the "powered by pretix" or "based on pretix" line, or when
-  indicating that a distribution is based on pretix.
-
-* You **may** use it to **indicate compatibility**, for example you are allowed to name your plugin "<name> for pretix"
-  or you may state that an external service is compatible with pretix.
-
-* You **may not** give the impression that your modified version, plugin or compatible service is official or authorized
-  by rami.io GmbH or pretix unless we specifically allowed you to do so.
-
-* You **may not** use it to name your modified version of pretix. End-users must be able to easily identify whether
-  a version of pretix is distributed by us.
-
-* You **may not** use any variations of the name, such as "MyPretix".
