Color Bloom is a coloring game that works offline. Every online feature below is optional; without a network the app colors and grows flowers exactly as before. The only exception is anonymous usage statistics (Google Analytics for Firebase, last row), which the app sends whenever it is online.

Data we process	Why	Kept
An anonymous account id (created by Firebase Authentication)	To back up your progress, garden and mood settings and show them on your other devices	Until you delete the account in Settings
Your Google account (optional; email and Google user id after linking)	To find the same garden on a new device	Same
Coloring progress, garden, moods, AI palettes	Cloud backup and sync	Same
Mood text for AI palettes (e.g. "rainy day, hot cocoa") and the picture's colours	Sent to the Anthropic Claude API to suggest a palette; no account or device identifiers are included	Results are cached for 30 days under a hash; the text itself is not stored
Photos you upload (Photo to line art)	Sent to our line-art server, converted, and deleted immediately; only the resulting SVG is kept, visible to you only	Photo: not stored. Line art: until you delete it or the account
Co-Coloring rooms (invite code, nickname, fills, cursor positions)	So everyone in a room sees each other's strokes live	Rooms are deleted after 24 hours
Daily challenge entries (thumbnail of your finished picture, mood, votes, reports)	Shown publicly on that day's wall for voting	Until you delete the account; three reports hide an entry
App Check / Play Integrity device tokens	To protect the backend from abuse	Short-lived, held by Google
Usage statistics (Google Analytics for Firebase: a random app-instance id, screens and events used, app version, device model, OS version, language, approximate country). The advertising ID is not collected	To see which features are used and where the app crashes or gets stuck	Up to 14 months, held by Google

Where data lives: on Google Firebase (Authentication, Firestore, Realtime Database, Cloud Storage, Cloud Functions, Google Analytics for Firebase; data centres in asia-east1 / asia-southeast1, Analytics data in Google's global infrastructure). Google is also used for the optional Google sign-in; Anthropic (Claude API) receives only mood text and picture colours; our own line-art service receives only the photo and deletes it after processing.
No ads, no sale of data, no cross-app tracking.
Age: online features are intended for users 13 and older.
Deletion: Settings → "Delete cloud data & account" removes the account, cloud progress and garden, your pictures and wall entries; local data is cleared too. You can also ask by e-mail from the Google account you linked; see how to delete your account.
Retention: Firebase keeps its own encrypted backups of the database; anonymous accounts with no cloud data that have not been opened for 30 days are purged automatically.
