Privacy Policy

Last updated: March 21, 2026

Overview

GridJoy is a number puzzle app. We respect your privacy and collect as little data as possible. This policy explains what we collect, why, and how we protect it.

What We Collect

• Account data: If you sign in with Google, we store your display name and email to sync your progress across devices. This is optional — the app works fully offline without an account.
• Puzzle progress: Solve history, mastery tiers, XP, streaks, and cosmetics. Stored locally on your device. Synced to Firebase only if you sign in.
• Anonymous analytics: Crash reports and basic usage metrics (puzzle type popularity, session length) via Firebase Analytics. No personally identifiable information.

What We Don't Collect

• No location data
• No contacts or phone data
• No browsing history
• No third-party tracking pixels
• No data selling — ever

Advertising

GridJoy uses rewarded video ads (optional, player-initiated). Ads never interrupt puzzle solving. Our ad partner (Google AdMob) may collect device identifiers for ad personalization. You can opt out of personalized ads in your device settings.

Data Storage

All puzzle data is stored locally on your device using AsyncStorage. If you sign in, your progress syncs to Google Firebase (Firestore) hosted in the US. Data is encrypted in transit (TLS) and at rest.

Children's Privacy

GridJoy is suitable for all ages. We do not knowingly collect data from children under 13. The app contains no violent content, no social features requiring personal information, and no unrestricted chat.

Your Rights

You can:

• Play entirely offline without creating an account
• Delete your account and all synced data by contacting us
• Export your puzzle history from the app settings

Changes

We may update this policy. Material changes will be announced in the app. Continued use after changes constitutes acceptance.
