Privacy Policy

These apps do not collect, store or share any personal data. They require no sign-up and no internet connection.

Progress, favorites and settings are stored only on your device and are deleted when you uninstall the app. Notifications are local and generated on the device itself.

The apps contain no advertising and no third-party analytics or tracking tools.

En Guardia can optionally add your shifts to the calendar on your device. For this it asks for calendar permission, which is used only for that action. The shifts are written directly to your device's calendar and are never sent to us or to any third party.

For Red Quiz on Android, there is a challenge mode in which two players compete on the same quiz in real time. This mode is optional and requires an internet connection.

To make this work, the following data is temporarily stored on Firebase Realtime Database (Google):

• The display name you enter before the match
• Your quiz answers (which questions you got right or wrong)
• Your score and time

This data is tied to a randomly generated 6-character challenge code and is not linked to any account, device identifier or personal profile.

All challenge data is automatically deleted from the database when the player who created the challenge disconnects. No data is retained after the match ends.

Reto is entirely optional. Players who do not use it are not affected by any of the above.
