Privacy Policy

Last updated: May 19, 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.
• In-app feedback: When you tap Send Feedback in Settings, your message is stored in Firestore so the developer can read and act on it. Along with the message we store your account ID (so we can follow up if needed), the app version, the platform (Android), and a timestamp. No feedback is collected unless you submit it. We do not currently collect crash reports or analytics events; if that changes in a future release, this policy will be updated before any new data starts being collected.
• Leaderboards (optional, Google Play Games): If you sign in with Google Play Games and submit a score to a public leaderboard, your Play Games player ID and chosen display name become visible to other GridJoy players viewing that leaderboard. You can leave or hide your profile from Play Games settings at any time.

What We Don't Collect

• No precise location — Google AdMob may infer approximate (city-level) location from your IP address to serve relevant ads, even with personalised ads disabled.
• No contacts or phone data
• No browsing history
• No third-party tracking pixels
• No data selling — ever

Advertising

GridJoy uses three ad placements, all served by Google AdMob:

• Rewarded videos — optional and player-initiated. You tap to earn a hint or recover a daily gift; you can ignore them entirely.
• One interstitial — may appear when you tap the Hub button after completing a puzzle (rate-capped and session-cooled).
• Banners on lobby screens — Home, Library, and Leaderboard only.

Ads never appear during puzzle solving.

Our ad partner (Google AdMob) receives, for the purpose of serving and measuring ads: your Google Advertising ID (GAID), basic in-app interactions during ad sessions, ad-delivery diagnostics, and approximate (IP-derived) location. You can reset your GAID, opt out of personalised ads, or delete it entirely under your device's Google settings → Ads.

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.
