Privacy Policy

Last updated: August 2026

numble ("we", "our", or "us") is committed to protecting your privacy. This policy explains what data we collect, why, and your rights over it. By using numble you agree to this policy.

1. Data we collect

Account data (if you register): email address and display name, stored in Firebase Authentication (Google LLC).

Your display name is published on the leaderboards alongside your scores, where anyone using numble can see it. It is the only account data other players can see. Your email address is never shown, and is never used to create your display name.

Game data: puzzle scores, completion times, and hint counts, stored in Cloud Firestore (Google LLC) and locally on your device.

Advertising data: if you consent on iOS, or by default on Android, Google AdMob may collect device identifiers and usage data to serve contextual advertisements. We have configured AdMob to serve G-rated content only.

2. How we use your data

To provide game features: saving progress, displaying leaderboards.
To improve the game: understanding which levels are played most.
To show ads: contextual ads fund free access to numble.

We do not sell your personal data to third parties.

3. Data retention

Your data is retained until you delete your account. Deleting your account removes your Firebase Auth record, all Firestore scores, and all locally cached progress on this device. Anonymised aggregate statistics may be retained.

4. Your rights

You have the right to:

Access the data we hold about you.
Delete your account and all associated data (in-app: Profile → Delete account).
Withdraw consent for personalised advertising at any time via your device settings (iOS: Settings → Privacy → Tracking; Android: Settings → Google → Ads).

EU/UK residents have additional rights under GDPR, including data portability and the right to lodge a complaint with your local supervisory authority.

California residents have rights under CCPA. We do not sell personal information.

5. Children's privacy

numble is rated 4+ and is suitable for all ages. We do not knowingly collect personal data from children under 13 without verifiable parental consent. If you believe a child has provided us with personal information, please contact us and we will delete it promptly.

Advertising in numble is configured to serve G-rated content only in compliance with COPPA.

6. Third-party services

numble uses the following third-party services, each with their own privacy policies:

Firebase Authentication & Firestore — Google LLC
Google AdMob — Google LLC

Google's privacy policy: https://policies.google.com/privacy

7. Security

Leaderboard data is stored in Cloud Firestore with security rules restricting each user to writing and deleting only their own records. Passwords are hashed by Firebase Authentication and are never stored by us. Local progress is stored in platform-protected app storage.

8. Changes to this policy

We may update this policy from time to time. Material changes will be communicated in-app. Continued use of numble after changes constitutes acceptance of the updated policy.
