Summary

The app has no ads, no tracking, no analytics and no built-in advertising, tracking or analytics components from third parties. There is no user account, and you enter neither an email address nor a name. Your player name for online games is rolled from word lists (for example "Wise Owl"). Data leaves your device only when you start an online game.

1. Offline games (Doppelkopf, Skat, Blindstich, Hexquad, Solitaire against bots)

Settings, the chosen card deck, bot level, statistics and the state of a Solitaire game in progress are stored only on your device. They are not transmitted.

2. Online play

When you choose "Online", the app connects over TLS to the game server spiele.hehmeyer.de, hosted at Oracle Cloud Infrastructure in Frankfurt, Germany.

• Data sent: your IP address (needed for the connection), your player name (put together from word lists, not typed freely) and the portrait you chose in the lobby, your moves, and the settings of the table you create or join and, if you send one, the number of a quick message.
• Visibility: other players at your table and in the table list see your player name and portrait.
• Table numbers: every table has a number. “Number only” tables are not shown in the table list; you join them with the number. If someone enters wrong numbers repeatedly, the server briefly limits attempts for that connection (in memory only, not stored).
• Reactions: at a table you can send fixed short messages (for example “Well played!”). Only the number of the sentence is sent, never free text. The other players see it briefly as a speech bubble. The server does not store it.
• Storage: there is no database. Game state, names and session tokens exist only in the server's memory and are discarded when the table ends or the server restarts. The one exception is the Solitaire daily deal (section 3).
• Server log: the server logs technical events (for example connections, rejected connections, rate-limit violations) without the IP address. The IP address is used only transiently in memory to limit the number of connections per address. Logs are kept for at most 7 days and then deleted automatically.
• Purpose and legal basis: providing online play and operating and protecting the server against abuse; Art. 6(1)(f) GDPR (legitimate interest).
• Sharing: none, except with the hosting provider Oracle as processor (data centre in Frankfurt am Main).

3. Solitaire daily deal (online)

When you play the daily deal under "Solitaire" in the online lobby, the app connects to the game server. Everyone gets the same deal on a given day. The ranking is anonymous.

• Data sent: a random installation ID generated by the app (no name, not tied to an account) and the move sequence of your game so the server can verify it. The ID is created on first start, exists only on your device, and is a new one after a reinstall. Technical connection data is handled as described in section 2.
• Stored: per day and installation ID, your best valid time and move count. No name and no IP address is stored, and there is no public list of players. You see only your own rank and the number of participants.
• Timing: the server measures the time itself to prevent cheating.
• Retention and deletion: the server deletes results automatically after 90 days. You can delete your results yourself at any time: online lobby → "Solitaire" → "Delete my results" (tap twice). The app then sends your installation ID to the server, which removes all results of that ID. You do not need to see or type the ID.
• Purpose and legal basis: providing a fair daily ranking; Art. 6(1)(f) GDPR (legitimate interest). The ID is a pseudonym; I cannot link it to a person without your help.

4. TestFlight and Google Play tests

If you get the app through Apple TestFlight, Apple processes data about your Apple Account, your device and any crash reports or feedback under its own privacy policy. The same applies to Google Play (including its test tracks): Google processes data about your Google Account, your device and crash reports under its own privacy policy. I have no control over that.

5. Voluntary tip (in-app purchase)

In Options you can voluntarily support the developer with a small amount. It unlocks nothing; all games stay free. The purchase is handled entirely by Apple (App Store) or Google (Google Play), as an in-app purchase. I receive no payment data, no name and no Apple ID or Google account, only the summarised sales statistics Apple and Google provide. Processing of your payment follows their privacy terms.

6. Your rights

You have the right to access, rectification, erasure, restriction, objection and data portability, and the right to lodge a complaint with a data protection authority, for example the Hamburg Commissioner for Data Protection and Freedom of Information (datenschutz-hamburg.de). Email the address above. Because the server has no accounts, stores no IP addresses and keeps logs only briefly, I can usually not link data to a person. You delete daily-deal results yourself in the app (online lobby, "Solitaire").

7. This website

This page is hosted by STRATO AG (Berlin, Germany). When you open it, the host processes technical connection data such as your IP address under its own privacy policy. I use no cookies, analytics or embedded third-party content on this page.

8. Changes

If the app or server changes in a way that affects this policy, I will update it. The date above shows the current version.
