-## More information 
-
-{{ config.mail_domain }} provides a low-maintenance, resource efficient and 
-interoperable e-mail service for everyone. What's behind a `chatmail` is 
-effectively a normal e-mail address just like any other but optimized 
-for the usage in chats, especially DeltaChat.
-
-
-### Rate and storage limits 
-
-- Un-encrypted messages are blocked to recipients outside
-  {{config.mail_domain}} but setting up contact via [QR invite codes](https://delta.chat/en/help#howtoe2ee) 
-  allows your messages to pass freely to any outside recipients.
-
-- You may send up to {{ config.max_user_send_per_minute }} messages per minute.
-
-- You can store up to [{{ config.max_mailbox_size }} messages on the server](https://delta.chat/en/help#what-happens-if-i-turn-on-delete-old-messages-from-server).
-
-- Messages are unconditionally removed latest {{ config.delete_mails_after }} days after arriving on the server.
-  Earlier, if storage may exceed otherwise.
-
-
-### <a name="account-deletion"></a> Account deletion 
-
-If you remove a {{ config.mail_domain }} profile from within the Delta Chat app, 
-then the according account on the server, along with all associated data,
-is automatically deleted {{ config.delete_inactive_users_after }} days afterwards. 
-
-If you use multiple devices 
-then you need to remove the according chat profile from each device
-in order for all account data to be removed on the server side. 
-
-If you have any further questions or requests regarding account deletion
-please send a message from your account to {{ config.privacy_mail }}. 
-
-
-### Who are the operators? Which software is running? 
-
-This chatmail provider is run by a small voluntary group of devs and sysadmins,
-who [publically develop chatmail provider setups](https://github.com/deltachat/chatmail).
-Chatmail setups aim to be very low-maintenance, resource efficient and 
-interoperable with any other standards-compliant e-mail service.

-# Privacy Policy for {{ config.mail_domain }} 
-
-{% if config.mail_domain == "nine.testrun.org" %}
-Welcome to `{{config.mail_domain}}`, the default chatmail onboarding server for Delta Chat users. 
-It is operated on the side by a small sysops team
-on a voluntary basis.
-See [other chatmail servers](https://delta.chat/en/chatmail) for alternative server operators. 
-{% endif %}
-
-
-## Summary: No personal data asked or collected 
-
-This chatmail server neither asks for nor retains personal information. 
-Chatmail servers exist to reliably transmit (store and deliver) end-to-end encrypted messages
-between user's devices running the Delta Chat messenger app. 
-Technically, you may think of a Chatmail server as 
-an end-to-end encrypted "messaging router" at Internet-scale. 
-
-A chatmail server is very unlike classic e-mail servers (for example Google Mail servers)
-that ask for personal data and permanently store messages. 
-A chatmail server behaves more like the Signal messaging server 
-but does not know about phone numbers and securely and automatically interoperates 
-with other chatmail and classic e-mail servers. 
-
-Unlike classic e-mail servers, this chatmail server 
-
-- unconditionally removes messages after {{ config.delete_mails_after }} days,
-
-- prohibits sending out un-encrypted messages,
-
-- does not store Internet addresses ("IP addresses"), 
-
-- does not process IP addresses in relation to email addresses.
-
-Due to the resulting lack of personal data processing
-this chatmail server may not require a privacy policy.
-
-Nevertheless, we provide legal details below to make life easier
-for data protection specialists and lawyers scrutinizing chatmail operations.
-
-
-
-## 1. Name and contact information 
-
-Responsible for the processing of your personal data is:
-```
-{{ config.privacy_postal }}
-```
-
-E-mail: {{ config.privacy_mail }}
-
-We have appointed a data protection officer:
-
-```
-{{ config.privacy_pdo }}
-```
-
-## 2. Processing when using chat e-mail services
-
-We provide services optimized for the use from [Delta Chat](https://delta.chat) apps
-and process only the data necessary
-for the setup and technical execution of message delivery.
-The purpose of the processing is that users can
-read, write, manage, delete, send, and receive chat messages.
-For this purpose,
-we operate server-side software
-that enables us to send and receive messages.
-
-We process the following data and details:
-
-- Outgoing and incoming messages (SMTP) are stored for transit
-  on behalf of their users until the message can be delivered.
-
-- E-Mail-Messages are stored for the recipient and made accessible via IMAP protocols,
-  until explicitly deleted by the user or until a fixed time period is exceeded,
-  (*usually 4-8 weeks*).
-
-- IMAP and SMTP protocols are password protected with unique credentials for each account.
-
-- Users can retrieve or delete all stored messages
-  without intervention from the operators using standard IMAP client tools.
-
-- Users can connect to a "realtime relay service"
-  to establish Peer-to-Peer connection between user devices,
-  allowing them to send and retrieve ephemeral messages
-  which are never stored on the chatmail server, also not in encrypted form.
-
-
-### 2.1 Account setup
-
-Creating an account happens in one of two ways on our mail servers: 
-
-- with a QR invitation token 
-  which is scanned using the Delta Chat app
-  and then the account is created.
-
-- by letting Delta Chat otherwise create an account 
-  and register it with a {{ config.mail_domain }} mail server. 
-
-In either case, we process the newly created email address.
-No phone numbers,
-other email addresses,
-or other identifiable data
-is currently required.
-The legal basis for the processing is
-Art. 6 (1) lit. b GDPR,
-as you have a usage contract with us
-by using our services.
-
-### 2.2 Processing of E-Mail-Messages
-
-In addition,
-we will process data
-to keep the server infrastructure operational
-for purposes of e-mail dispatch
-and abuse prevention.
-
-- Therefore,
-  it is necessary to process the content and/or metadata
-  (e.g., headers of the email as well as smtp chatter)
-  of E-Mail-Messages in transit. 
-
-- We will keep logs of messages in transit for a limited time.
-  These logs are used to debug delivery problems and software bugs.
-
-In addition,
-we process data to protect the systems from excessive use.
-Therefore, limits are enforced:
-
-- rate limits
-
-- storage limits
-
-- message size limits
-
-- any other limit necessary for the whole server to function in a healthy way
-  and to prevent abuse.
-
-The processing and use of the above permissions
-are performed to provide the service.
-The data processing is necessary for the use of our services,
-therefore the legal basis of the processing is
-Art. 6 (1) lit. b GDPR,
-as you have a usage contract with us
-by using our services.
-The legal basis for the data processing
-for the purposes of security and abuse prevention is
-Art. 6 (1) lit. f GDPR.
-Our legitimate interest results
-from the aforementioned purposes.
-We will not use the collected data
-for the purpose of drawing conclusions
-about your person.
-
-
-## 3. Processing when using our Website
-
-When you visit our website,
-the browser used on your end device
-automatically sends information to the server of our website.
-This information is temporarily stored in a so-called log file.
-The following information is collected and stored
-until it is automatically deleted
-(*usually 7 days*):
-
-- used type of browser,
-
-- used operating system, 
-
-- access date and time as well as
-
-- country of origin and IP address, 
-

-
-This website is hosted by an external service provider (hoster).
-The personal data collected on this website is stored
-on the hoster's servers.
-Our hoster will process your data
-only to the extent necessary to fulfill its obligations
-to perform under our instructions.
-In order to ensure data protection-compliant processing,
-we have concluded a data processing agreement with our hoster.

-
-- Ensuring a reliable connection setup of the website,
-
-- ensuring a convenient use of our website,
-
-- checking and ensuring system security and stability, and
-
-- for other administrative purposes.
-
-The legal basis for the data processing is
-Art. 6 (1) lit. f GDPR.
-Our legitimate interest results
-from the aforementioned purposes of data collection.
-We will not use the collected data
-for the purpose of drawing conclusions about your person.
-
-## 4. Transfer of Data
-
-We do not retain any personal data but e-mail messages waiting to be delivered 
-may contain personal data.
-Any such residual personal data will not be transferred to third parties
-for purposes other than those listed below:
-
-a) you have given your express consent
-in accordance with Art. 6 para. 1 sentence 1 lit. a GDPR,  
-
-b) the disclosure is necessary for the assertion, exercise or defence of legal claims
-pursuant to Art. 6 (1) sentence 1 lit. f GDPR
-and there is no reason to assume that you have
-an overriding interest worthy of protection
-in the non-disclosure of your data,  
-
-c) in the event that there is a legal obligation to disclose your data
-pursuant to Art. 6 para. 1 sentence 1 lit. c GDPR,
-as well as  
-
-d) this is legally permissible and necessary
-in accordance with Art. 6 Para. 1 S. 1 lit. b GDPR
-for the processing of contractual relationships with you,  
-
-e) this is carried out by a service provider
-acting on our behalf and on our exclusive instructions,
-whom we have carefully selected (Art. 28 (1) GDPR)
-and with whom we have concluded a corresponding contract on commissioned processing (Art. 28 (3) GDPR),
-which obliges our contractor,
-among other things,
-to implement appropriate security measures
-and grants us comprehensive control powers.
-
-## 5. Rights of the data subject
-
-The rights arise from Articles 12 to 23 GDPR.
-Since no personal data is stored on our servers,
-even in encrypted form,
-there is no need to provide information
-on these or possible objections.
-A deletion can be made
-directly in the Delta Chat email messenger.
