Effective 5 October 2026.
Rooklume is a chess and draughts app for children and adults: lessons, puzzles, play against a bot and online play. It has no ads, no purchases and no free-text chat: in an online game players can only exchange preset phrases from a list. We store data for online play and learning progress backup.
Settings (language, look, sound), “My games”, and parental usage minutes and daily limits stay on your phone and are removed when you uninstall the app.
Academy progress (lessons and stars) and puzzle progress (solved puzzles, learning rating and streak) are stored on your phone and automatically synced to a server account without a real name (a pseudonymous account) when online. Along with it, the server stores the days on which daily goals were completed (which of the three) and personal bests in puzzle modes. The first sync creates an account without a real name or email address. A recovery code restores backed-up progress on a new phone. Learning works offline; changes not yet uploaded can be lost if you uninstall the app. Deleting your account removes its server progress and disables automatic sync.
One account serves both games. Their learning progress, competitive ratings and games are stored separately. Mentor narration uses the device’s system speech; the app does not record the microphone.
The first learning progress sync, opening “Online & tournaments”, or playing the “Masters” creates a pseudonymous server account — with a game name and random identifier:
Playing the “Masters” (Play the bot → Masters): the app sends the moves of the current game to the server so the opponent can reply. These games are not stored on the server.
Game review: when online, the app sends the game’s moves to the server so the engine can find mistakes. No account is created for this; the moves are processed only during the review and are not stored on the server. Offline, the review runs on the phone.
Player rankings (Online & tournaments → Player rankings): other players see the game name, avatar and rating of those who have played at least 10 rated games. A child profile sees only the kids’ table, an adult profile only the adults’ table.
The app does not ask for real names, email addresses, phone numbers, photos, location, contacts or advertising IDs. It contains no analytics, ads or third-party trackers. If you choose to email support, we receive the sender address and message contents to reply and handle your request. Messages and our replies are kept in the support mailbox on our server and in its daily backups. Each message is deleted automatically 12 months after it was received or sent, or earlier if you ask at support@rooklume.com. Do not send a child’s personal information or account secrets.
The server keeps a technical error log without personal data. Like any internet service, the server sees the device IP address while connected, but does not store it in the database.
Rooklume is made for children. On first launch an adult confirms the child profile. In quick pairing a child profile plays only against other child profiles; we do not verify age — the profile is chosen by an adult on first launch. Family members can play via an invite code. There is no free communication between players: in an online game you can only send one of the preset phrases from a list (“Hi!”, “Nice move!” and so on); typing your own text is not possible. Phrases are not stored on the server: it only relays them to the opponent. Phrases can be turned off in Settings, and in a child profile only in the Parents section, behind the parental check. Before first use a child profile sees a reminder not to tell anyone in games their name or address.
As long as the account exists. In-app deletion: Settings → Delete online account. An internet connection is required; finish participating in an active online game or tournament first. Once deletion succeeds, the account, learning progress for both games, ratings, games and finished tournaments are removed from the live database. Local progress stays on the phone and automatic sync is disabled. Deleted data may remain in backups accessible only to the developer for service recovery. Daily working-database backups are rotated; a single automatic deletion period for separate emergency and archived backups is not currently guaranteed. Contact support@rooklume.com with questions about deleting those copies.
To submit a request without reinstalling the app, email support@rooklume.com with the subject “Rooklume account deletion”. You may include your game name if you remember it. Do not send your recovery code, access key or passwords. Support must verify account ownership before deletion; a game name alone is not enough. If you lost your device and recovery code, tell us: we cannot delete another person’s data without verifying ownership.
Only the Rooklume developer, to run and protect the service. We do not sell or share data with third parties.

We will announce material changes to this policy in the app.
