Patte is a card game app. This page describes what data the app collects and how it's used.

What we collect

• Display name — a name you type in yourself in the app, shown to the other players in your game. We never read this from your phone's contacts, account, or device settings — it's whatever you type, and can be anything you like.
• A randomly-generated profile id — created on your device the first time you play (locally or online), used to identify your seat across an online game session and, in aggregate, to count how many distinct devices are actually playing the app. It isn't tied to your real identity, an email address, or any account.
• Live game data — the cards, room codes, and moves needed to run a multiplayer game while it's in progress.

What we don't do

No ads, no third-party analytics or tracking SDKs, no third-party data sharing or selling.

Aggregate usage counts

The server keeps a running count of anonymous events like "a Rummy game started online" or "a Rummy game started against bots" (locally or online) — just a number per event type, with no per-user identifiers, timestamps tied to a person, or gameplay details attached. This tells us which games are actually being played, and how, so we know what to improve. Starting a local (vs-bot) game sends a lightweight one-off signal with just the event name and your device's profile id — nothing about the game itself.

Crash & error reporting

If the app or server hits an unexpected error, technical details (device/OS info, app version, and a stack trace of the code that failed) are sent to Sentry, a bug-tracking service, so we can find and fix the problem. This is used solely for that purpose — not for analytics, advertising, or tracking your activity.

Storage

Your display name and profile id are stored on our server so you can be recognized across rooms and sessions. Starting a game — even a local one against bots — creates or updates a minimal record for your device's profile id (with no display name attached until you play online), so we can tell how many distinct devices are actually using the app. In-progress game state lives only in server memory while a game is active. Data is hosted on Fly.io infrastructure.

Deleting your data

The app has a "Delete my data" button (in the main menu) that immediately deletes your display name and profile id from our server and clears everything stored on your device. Alternatively, you can email adevelopera@gmail.com from any address with your in-app display name (or profile id, if you have it), and we'll delete the corresponding record within a few days and reply to confirm.
