Privacy Policy

Effective date: 2026-06-09 (revised same day to disclose Sentry crash reporting)

This Privacy Policy describes how Gamexercise ("the app", "we", "us") handles your information. We built Gamexercise to be a privacy-respecting fitness RPG: your data stays on your device. We do not run servers that store your information, and we do not share your data with third parties.

1. Information we access

Step count (via Apple HealthKit)

Gamexercise reads your daily step count from Apple HealthKit to power in-game progression — gold earned, character levels, daily quests, outfit unlocks. The first time you tap "Tap to Start" and complete the tutorial, iOS will ask for your permission to share step data with the app. You can decline, change your mind later in iOS Settings → Privacy & Security → Health → Gamexercise, or play the game without HealthKit (your in-game progression simply won't accumulate from real walking).

Step data stays on your device. The app reads it in-process, applies it to the local game state, and discards the raw value. We never transmit step data to any server, third party, or analytics service.

Local game state

Game state — your character, gold, level, owned outfits, quest progress, settings — is written to a single save file in the app's private storage on your device (Application.persistentDataPath). It is not synced to iCloud, not backed up to our servers (we have none), and is not accessible to other apps.

Crash + error diagnostics (Sentry)

When the app crashes or hits an unhandled exception, Gamexercise sends a diagnostic report to Sentry, a third-party error-monitoring service. The report contains:

• The exception message and call stack (which code line failed).
• Device model, OS version, and app version.
• The user's preferred language / locale code.
• A short trail ("breadcrumbs") of the last ~100 log entries leading up to the crash, used only to reproduce the bug.

The report does not contain:

• HealthKit step data or any health metric.
• Your game save (character / gold / quests / outfits).
• Your name, email, IDFA, or any identifier that could link the crash to you. We don't have accounts.
• Your IP address — Sentry's SendDefaultPii setting is explicitly disabled, so IPs are stripped server-side before storage.

We use this data solely to fix bugs. Sentry retains crash reports for 90 days then deletes them. Their privacy policy is available at sentry.io/privacy.

2. Information we do not collect

• No personal information. We do not ask for your name, email, phone number, address, or any account credentials.
• No location data. We do not request location permissions.
• No device identifiers used for tracking. We do not collect your IDFA, IDFV, or any advertising / tracking identifier. (Sentry's crash report includes the device model but not a per-device unique ID.)
• No analytics. The app does not include any analytics SDK (no Firebase, Mixpanel, Amplitude, etc.).
• No ads. Gamexercise contains no advertising.
• No third-party tracking. The app does not contact any tracking domains. (Sentry collects crash diagnostics only when something breaks; this is not tracking under Apple's ATT framework.)

3. How we use the information we access

Step data and local game state are used solely to:

• Compute your in-game level, gold balance, and quest progress from your real-world activity.
• Render your character with the outfits, skins, and achievements you've earned.
• Persist your progress across app launches so you don't lose progress.

4. Data sharing

We do not share, sell, rent, license, or otherwise transfer your data to any third party for marketing or commercial purposes.

The single processor we use is Sentry, who acts on our behalf strictly to store the crash diagnostics described in Section 1. Sentry does not use the data for their own marketing, does not share it with third parties, and is bound by their own published privacy policy.

If we add features in a future version that involve transmitting other data — for example, Apple Game Center leaderboards (where leaderboard scores are sent to Apple's Game Center servers, not ours) — this policy will be updated before that feature ships, and the relevant data flows will be disclosed here and in the App Store privacy nutrition card.

5. Your choices

• HealthKit access: Grant or revoke at any time in iOS Settings → Privacy & Security → Health → Gamexercise. Revoking access means the app simply stops receiving step updates; your existing game progress is preserved.
• Reset your save: Open the in-app Settings screen and tap "Reset progress" twice to wipe the local save file. This is irreversible — there is no cloud backup we can restore from.
• Delete the app: Uninstalling Gamexercise removes the save file and any cached data. Nothing about you remains on our side because we never received anything to begin with.

6. Children's privacy

Gamexercise is rated for general audiences. We do not knowingly collect any information from children. The app does not have account creation or user-generated content. If you are under 13 (or the applicable age of digital consent in your jurisdiction) and have any concerns, please contact us.

7. Security

Because Gamexercise does not transmit your data, there is no in-flight encryption to maintain on our end. The local save file is stored inside the app's sandbox, which iOS isolates from other apps. iOS's standard device protection (passcode, Face ID, Touch ID) applies.

8. Changes to this policy

We will update this policy if Gamexercise's data practices change — for example, if a future version adds a new SDK, transmits data to a server, or enables Game Center / iCloud sync. The "Effective date" at the top of this page will be updated, and material changes will be surfaced in the app's release notes on the App Store.
