Privacy policy
Draft. Chrome Horizons is in development and not yet available. This policy describes how the app is designed to work and will be finalised before release. Last updated: 11 November 2026.
The short version
- We collect a summary of each run: when it started, how long it took, how far you went and how much you climbed.
- We never collect your routes, your location, or your heart rate.
- Other runners see only your display name, your avatar, your position on the track and a few weekly totals.
- We do not sell your data or use it for advertising.
- You can delete your account and all your data from inside the app.
Who we are
Chrome Horizons is operated by [OPERATOR NAME] ("we", "us"). You can reach us at [CONTACT EMAIL].
What we collect
| Data | Where it comes from | Why we need it |
|---|---|---|
| Account identifier | Sign in with Apple | To recognise your account. We do not receive your Apple password. If you choose to hide your email, we receive Apple's private relay address. |
| Display name and avatar choices | You | To show you on the track. |
| Run summaries: start time, duration, distance, elevation gain, and whether the run came from Garmin or Apple Health | Garmin Connect or Apple Health, with your permission | To move you along the track, award Season XP and set your weekly challenges. |
| Game progress: track position, Season XP, unlocked items, challenge progress | Calculated from your run summaries | To run the game. |
| Cheers you send and receive, and any reports or blocks you make | You | To deliver cheers and keep the track safe. |
| Notification token | Your device, if you allow notifications | To send the notifications you turned on. |
| Crash reports and basic usage statistics | The app | To fix problems and improve the app. These are not used to build an advertising profile. |
What we never collect
- GPS routes, maps or any location data.
- Heart rate, sleep, weight or any other body measurements.
- Your contacts, photos or advertising identifier.
Garmin and Apple Health can make more data available than we use. We read only the run fields listed above and discard everything else.
What other runners can see
Chrome Horizons is a shared track, so some information is visible to other players:
- your display name and avatar, including the items you have equipped;
- your position on the track this season;
- the number of runs you have logged this week, and badges you have earned;
- a trail coloured by the kinds of run you have done recently, such as long runs or hills.
Other runners never see the details of an individual run, such as its time of day, pace, distance or duration. Choose a display name that does not identify you if you prefer to stay anonymous.
Garmin and Apple Health
You choose whether to connect Garmin Connect or Apple Health, and you can disconnect either at any time, in the app or in Garmin's or Apple's own settings. When you connect Garmin, your runs are also subject to Garmin's privacy policy.
Data from Apple Health and Garmin is used only to provide the game. We do not use it for advertising or marketing, and we do not sell it or share it with data brokers. We do not store health data in iCloud.
Who we share data with
We do not sell personal data. We use a small number of service providers who process data on our behalf, under contract, only to run the app:
- Supabase, which hosts our database and sign-in service;
- Apple, for sign-in and notifications;
- Garmin, when you connect a Garmin account;
- TelemetryDeck, for anonymous usage statistics.
We may also disclose information if the law requires it.
How long we keep it
We keep your data for as long as you have an account. When you delete your account, we delete your profile, run summaries and game progress within 30 days. Backups are overwritten within a further [BACKUP PERIOD].
Your choices and rights
- Delete your account in the app under Settings. This removes your data and takes you off the track.
- Get a copy of your data or ask us to correct it by writing to [CONTACT EMAIL].
- Disconnect a data source at any time. New runs stop arriving immediately.
- Block or report another runner from their card on the track.
Depending on where you live, you may have further rights under laws such as the GDPR or the CCPA, including the right to object to processing and to complain to your local data protection authority. Write to us and we will respond within 30 days.
Children
Chrome Horizons is not intended for children under 13, and we do not knowingly collect their data. If you believe a child has created an account, contact us and we will delete it.
Security
Data is encrypted in transit and at rest. Access rules in our database prevent one runner's account from reading or changing another runner's private data. No system is perfectly secure, and we will tell you promptly if a breach affects your data.
Changes to this policy
If we change this policy in a way that matters, we will tell you in the app before the change takes effect.
