Colibri ("the app") helps you quit sugar with friends through daily challenges, streaks, and leaderboards. This policy explains what data the app handles and where it goes. The short version: there are no accounts, your journal stays on your device, and we never sell data or show third-party ads.
The app does not ask for your email, phone number, or any login. On first launch it creates a random, anonymous device identifier (via Firebase Anonymous Authentication) that links your challenge participation across syncs. It is not tied to your identity.
Your journal notes and mood ratings are stored only in the app's local database on your device. They are never uploaded to our servers.
To make shared challenges work, the following is stored in Google Firebase (Cloud Firestore):
This data is readable only by participants of the same challenge — that's what powers the shared leaderboard. It is not public.
The app uses Firebase Analytics to understand which features are used (for example, "a journal entry was logged"). These events do not contain your notes, names, or any content you write. The app does not use advertising SDKs and does not track you across other apps or websites.
The app is not directed at children under 13 and does not knowingly collect personal information from them.
If this policy changes materially, the updated version will be posted at this address with a new date.
Questions or deletion requests: use the support link on the app's App Store page.
