privacy policy
Who the app is for
tir (“we”, “the app”) is operated by Aman Shrivastava (trading as aaam.dev). This policy describes how we handle information when you play tir on a mobile device. The app is rated 4+ and not directed at children under 13.
Anonymous accounts by default
tir does not require email, phone number, or password. When you first launch the app, we create an anonymous account on your device using Firebase Authentication. The anonymous account is tied to your installation, not to your identity. Sign out, reinstall, or tap “delete account” at any time to discard it.
Information we collect
Profile
- A display name you choose during onboarding (so other players can see who they're racing).
- An avatar emoji you pick from a 30-emoji grid.
- An anonymous Firebase user ID generated on first launch.
Game-play data
- Your Elo rating, league tier, rounds played, rounds won, win streak, and last-round score delta.
- Your current word and the four options shown to you, only while a round is in flight.
- Your membership in the global room and any private rooms you create or join.
Operational data
- Standard authentication and security signals collected by our infrastructure providers (e.g. authentication events, IP address, device type) to operate and secure the service.
We do not collect: email, phone number, location, contacts, photos, microphone audio, health data, advertising IDs (IDFA), or any tracking identifiers.
How we use information
- To run the global room and private rooms (matchmaking, target-word picks, scoring).
- To compute your Elo rating and place you on the leaderboard.
- To show your display name and avatar to other players in the same room.
- To operate, secure, and improve reliability of the service.
We do not sell your data. We do not show ads. We do not use any third-party analytics, tracking SDKs, or attribution tools.
Where data is processed
We use Google Firebase (Authentication, Firestore database, Cloud Functions) to host backend data. Data may be processed in the United States and other countries where Google operates. See Google’s Firebase documentation for more on subprocessors.
Retention and deletion
We retain your data while your account exists and as needed to operate the service.
How to delete your account
You can permanently delete your account and all linked data from inside the app:
- Open tir.
- Scroll to the bottom of the home screen.
- Tap the red “delete account” button.
- Confirm in the alert.
What gets deleted:
- Your Firebase Authentication record (the anonymous user).
- Your private user profile (display name, avatar, Elo, streaks, rounds played).
- Your public leaderboard entry.
- Your active membership in any room.
Past round-result blobs may retain your anonymous user ID as part of operational logs (chess.com / League of Legends post-deletion convention). These are not user-facing and are not linked to any contact information.
If you cannot access the app, email support@aaam.dev with the approximate date of your last play and we will process the deletion within 7 days.
Security
We use industry-standard transport encryption (HTTPS) for client communication with Firebase. Firestore security rules restrict reads and writes to the data that belongs to your account.
Changes
We may update this policy from time to time. We will post the new policy at this URL and update the “Last updated” date.
