Privacy Policy

1. Riichi Sensei collects nothing

From version 1.2 on iPhone and iPad, and version 2.0 on Android, Riichi Sensei collects no information about you or how you use it, and shares none. It has no analytics, crash reporting, advertising or accounts, and it never connects to the internet.

Its links to this website and to our support email open in your browser or your mail app, whose own policies apply.

2. What stays on your device

The app keeps its settings and its reference content on your device and never sends them anywhere. Deleting the app deletes them.

3. Versions 1.0 and 1.1

Earlier versions included Google's Firebase Analytics and Firebase Crashlytics. They asked whether you agreed to usage statistics and crash reports, and if you did, they could send:

• which features you used, and what you searched for in the encyclopedia;
• your device model, system version and app version, and your approximate location (country or region);
• crash reports.

Firebase could also record the app's first launch before you answered. None of it included your name, email address or other contact details. Updating to version 1.2 on iPhone and iPad, or 2.0 on Android, stops all of it, and we'll delete the data Firebase holds once version 2.0 is available on Google Play.

4. Children

Riichi Sensei is suitable for all ages. From those versions it collects nothing from anyone, children included.

5. Changes to this policy

If a future version needs to collect anything, we'll update this policy first, and the app will ask for your agreement before it collects.
