Privacy Policy

Sudoku by Fabcode · Last updated: 5 May 2026

This Privacy Policy describes how Sudoku by Fabcode ("the App", "we", "us") handles information when you use our mobile application on iOS and Android. We have built the App to collect as little personal data as possible.

1. Information we collect

1.1 Information you provide

Nickname — an optional display name (max 20 characters) used in Versus mode. It is stored on your device and shared only with opponents in rooms you join. It is not linked to your real identity.

1.2 Information collected automatically

Data	Purpose	Where it goes	Retention
Device type, OS version, app version	Crash diagnostics, analytics	Sentry, PostHog	90 days
Crash logs & stack traces	Fix bugs	Sentry	90 days
Anonymous usage events (screen views, game completions, VS races)	Improve the App	PostHog	12 months
Approximate region (from IP, never stored verbatim)	Aggregate metrics	PostHog	12 months
Advertising identifier (IDFA on iOS / AAID on Android)	Ad delivery & frequency capping	Google AdMob	Per Google policy
VS room code, ephemeral player ID, game progress	Run live races	Cloudflare Workers (our backend) — discarded when room closes	Up to 1 hour

1.3 Information we do not collect

We do not require an account, email address, phone number, or sign-in.
We do not access your contacts, photos, microphone, camera, or precise location.
We do not sell personal data to third parties.

2. Advertising

The App displays ads served by Google AdMob. On iOS, you will be asked via Apple's App Tracking Transparency prompt whether to allow tracking. In the European Economic Area, the United Kingdom, and Switzerland, you will see a Google UMP consent screen the first time you launch the App. You can change your consent at any time from Settings → Privacy. If you decline, you will still see ads, but they will be non-personalised.

3. Children's privacy

The App is rated for general audiences and does not knowingly collect personal information from children under 13 (or under 16 in the EEA). If you believe a child has provided personal information, please contact us and we will delete it.

4. Account & data deletion

You can delete all locally stored data at any time:

In the App: Settings → Delete all data. This wipes your nickname, statistics, saved game, and Versus state from your device. The action is irreversible.
VS-mode data on our servers (room state) is automatically discarded when the room closes (typically within minutes; never longer than 1 hour).
To request deletion of any analytics or crash data we hold, email privacy@fabcode.example with the device ID shown in Settings → About. We will respond within 30 days.

5. Your rights (GDPR / CCPA)

If you are in the EEA, the United Kingdom, or California, you have the right to access, correct, delete, or port your personal data, and to object to processing. Contact us at the email above to exercise any of these rights.

6. Data security

All network traffic between the App and our servers is encrypted with TLS. Crash and analytics data is transmitted over HTTPS to the providers listed above. We do not store payment information.

7. Third-party services

8. Changes to this policy

We may update this policy from time to time. The "Last updated" date at the top of the page will reflect the most recent change. Material changes will also be announced inside the App.
