1. Overview
Colmo is a number puzzle. It is playable entirely offline and requires no account. This page describes the small amount of data the game handles and why.
2. What we process
- Game progress (levels cleared, stars, best endless score, which helper lessons you have seen): stored on your device. If the device is online, the same data is synced to Google Firebase under an anonymous identifier so it can be recovered on a new device. No name, e-mail or contact detail is part of that record.
- Optional Google sign-in: if you choose it, your anonymous save is linked to your Google account so it survives a change of device. We receive only the basic profile (e-mail address) Google provides for authentication. Signing in is never required to play.
- Settings (sound, music, language, haptics): stored on your device only.
- Gameplay measurement (Google Analytics for Firebase): the game records what happened, not who you are. Which level was started, won, lost or left, how many doses it took, which helper was used, whether a language was changed. This exists to answer one question: where the game is too hard or unclear. Advertising identifiers, ad personalisation and ad-related data are switched off in code.
- Crash reports (Firebase Crashlytics): if the game crashes, the technical details of the crash are sent (device model, OS version, the point in the code that failed). A game that crashes silently is a game nobody reports.
3. What we do not do
- No ads and no advertising SDKs at launch.
- No advertising ID, no ad personalisation, no tracking across apps or sites.
- No location, no contacts, no photos, no microphone.
- No selling or sharing of data with third parties.
4. Where the data lives
Cloud saves are stored in Google Firebase (Firestore) in the project colmo-bardino. Access rules restrict every record to the account that owns it. Firebase's own processing is covered by Google's privacy documentation.
5. Deletion
Uninstalling the app removes local data. To delete a cloud save, see Account deletion.
6. Children
Colmo contains no chat, no user-generated content and no ads. It does not knowingly collect personal data from children; the only optional personal datum in the product is the Google e-mail used for sign-in.
7. Changes
Material changes to this policy will be reflected here with a new date.
