About Us

🚲 We are a small crew of riders and tinkerers who got tired of guessing how worn our chains were. Chain Garage is the logbook we wished hung on our workshop wall.

🛠️ Our mission is simple: make bike care so clear and satisfying that nobody skips it. Maintenance should feel like progress, not a chore you remember at the bottom of a hill.

📊 The app gives you a garage for every bike, health bars for each part, pre-ride checklists, tire pressure and gear calculators, repair notes with photos, and XP, achievements and streaks to keep you rolling.

Ride more, fix less. Keep it rolling.

Chain Garage does not collect, store or transmit any data. Everything runs locally on your device.

1. Information We Collect

None. We do not collect personal information, usage data, device identifiers, location, or analytics of any kind. The bikes, parts, mileage, checklists, repair notes and photos you enter never reach us.

2. How We Use Information

Because we receive no information, there is nothing for us to use, analyze, share or sell. Your XP, ranks and streaks are calculated on your phone only to power the game inside the app.

3. Data Storage

All of your garage data is stored locally on your iPhone. There is no cloud storage, no server and no sync service operated by us.

4. Third-Party Services

Chain Garage contains no analytics tools, advertising networks, social plug-ins or trackers. The app works fully offline and makes no network requests on your behalf.

5. Data Security

Your data stays within the app's storage on your device and benefits from the protections of iOS, such as your passcode and device encryption. Since nothing is transmitted, there is nothing to intercept in transit.

6. Children's Privacy

We do not knowingly collect information from anyone, including children under 13. The app has no accounts, no ads and no data collection, which makes it consistent with COPPA expectations.

7. Your Control

You are in full control. There are no accounts to manage. You can edit or remove entries at any time, and deleting the app removes all of its data from your device.

8. Changes to This Policy

If we update this policy, we will publish the new version on this page with a revised effective date. Our core promise of collecting no data will not change quietly.
