Privacy Policy

Last updated: 2026-04-16

Hot & Cold is operated by Lambda 7 Tech LLC (“we”, “us”). This policy explains what data the app may process, why we process it, and your choices.

1. Data we generally do not collect

No contact list, photo library, or precise location data for core gameplay.
No location data of any kind.
No mandatory sign-in for core gameplay in current builds.
No analytics SDK in current builds.

2. Data stored on your device

The app stores gameplay state locally so your experience can resume between sessions, including progress, stats, and display preferences.

You can wipe everything via Settings → Reset data → Reset everything, or by uninstalling the app.

3. Multiplayer

When you play multiplayer, the display name you choose and the gameplay data needed to run the match are processed by our backend. Multiplayer data is temporary and retained only as long as needed to operate active sessions.

4. App content

The app may download and cache game content over HTTPS so features work reliably across sessions.

5. Daily mode

Daily mode uses our backend to run the puzzle and keep your progress consistent across sessions.

6. Advertising

Monetization may change over time. If advertising is introduced, this policy will be updated to describe what data is used and why.

7. Crash logs and errors

We may collect diagnostic data to maintain app reliability. If this changes materially, we will update this policy.

8. Service providers

We rely on infrastructure and hosting providers to operate the Service. As with any internet service, providers may receive standard request metadata (for example IP address and user agent) in transit.

Cloudflare — hosting and infrastructure services.

9. Children

Hot & Cold is suitable for general audiences and does not knowingly collect data from children under 13. If you believe a child has provided personal data via our Service, contact us and we will delete it.

10. Your rights

Because we don't collect personal data tied to an identity, there is generally nothing for us to delete on our servers. You can:

Wipe local data inside the app (Settings → Reset data).
Uninstall the app to remove everything.
Contact Lambda 7 Tech LLC at [email protected] with any privacy questions.

11. Changes

We may update this policy. Material changes will be reflected by an updated date at the top of this page.
