Version 1.0.0 · Updated 27 October 2026
Language versions
The German original is the authoritative version of this document. This English version is a translation for your information. If the versions differ, the German version prevails. Mandatory statutory rights and disclosure obligations remain unaffected.
Scope
This policy applies to the Android app schukai Chat, package name com.schukai.chat. The app shows conversations from your Matrix accounts and, optionally, from Workspace connections in one shared list.
Controller and contact
schukai, Eichenstraße 26, 82290 Landsberied, Germany, is responsible for the app. Contact hey@schukai.com for privacy questions. The linked imprint contains the full provider identity and further contact details.
schukai runs no chat server or relay for the app. Your messages are held by the servers you connect. The respective server operator is responsible for these data; for a Workspace connection, this is the company that runs that Workspace. Its privacy notice also applies.
Matrix accounts
You sign in to a Matrix server of your choice with server, user ID and password. The app sends these details over HTTPS only to that server. It does not store the password. The app then exchanges conversations, participant details and messages with the server when you open conversations, load older messages or send a message yourself.
The app cannot currently decrypt messages in end-to-end encrypted rooms; it shows a notice there and sends no messages into such rooms.
Workspace connection
You can optionally connect the app to a company's Workspace by QR code, for example to answer website conversations. The app asks for camera access to scan the code. The camera image is evaluated on the device only and not stored. After you confirm in the browser, the app receives a session for this Workspace and exchanges the conversations you are allowed to handle there.
What stays on your device
The app stores sessions, loaded conversations, drafts and delivery states encrypted in its private storage, separately per account. Settings such as appearance, filters and language stay local. Android's automatic backup is disabled.
The app contains no advertising, no usage analytics and no tracking. It collects no location and no contacts and uses no push notifications. It needs internet access for connections and the camera for scanning QR codes.
Purposes and legal bases
schukai provides the app so that you can use your own accounts. Data are transmitted to the servers you connect at your request in order to use the chat service (Art. 6(1)(b) GDPR in relation to the respective server operator). schukai processes support details to handle your request.
Google Play
Google processes details about installation, updates and the store under its own privacy policy, including the international processing described there. Depending on your Android settings, Google may also receive crash and performance diagnostics.
Deletion
When you remove an account in the app, the app deletes its session, loaded messages and the related key on the device. You can also clear the history of a single account. Uninstalling removes all local data. Your account and messages on the server are not affected; contact the server operator for that.
Your rights
Subject to the legal requirements, you can request access, rectification, erasure, restriction and data portability and object to processing based on legitimate interests. You can lodge a complaint with a data protection supervisory authority.
Because schukai does not receive your messages, schukai can neither attribute them to a person nor disclose them. Direct requests about data on a server to its operator.
Changes
We update this policy before new data flows go into production, for example push notifications, file transfer or services run by schukai. The date at the top identifies the current version.
