Privacy Policy

This policy explains what data Circloop handles, where it lives, and the few narrow cases where your device talks to anyone at all.

Who we are

Circloop is published by ODAMIT.

ODAMIT (as named above) is the controller for the limited processing described here. Website: odamit.com.

Data stored on your device only

The following is created and stored locally on your iPhone (and Apple Watch) and is never transmitted to ODAMIT or to any third party by us:

• Activity history — your recorded runs and walks: route track, distance, duration, pace, splits, calories, heart-rate summaries.
• Saved routes and best times (for ghost racing).
• Goals, achievements, and statistics.
• Settings and preferences (units, theme, reminders, and so on).

Deleting the app deletes this data. There is no copy anywhere else — which also means we cannot recover it for you.

Apple Health (HealthKit)

With your permission, Circloop:

• reads heart rate, active energy, and body weight — to show live metrics and estimate calories;
• reads back workouts that Circloop itself recorded on your Apple Watch, so those sessions appear in your activity history (the import feature);
• writes your finished sessions as workouts (including the route) to Apple Health.

Health data is exchanged only between the app and Apple Health on your device, under Apple's HealthKit rules. We never receive it, and we never use Health data for marketing, advertising, or any purpose beyond the app's visible features. You can review or revoke access at any time in the Health app (Profile → Privacy → Apps → Circloop).

Location

Circloop uses your location on-device to set your starting point, follow your position during a session, and record your track. Your location history is stored only in your local activity history (see above).

When you generate a route, the route calculation is performed by Apple Maps (Apple's MapKit service) — the same as asking Apple Maps for walking directions. This request is handled under Apple's privacy policy; ODAMIT does not receive or store it.

Motion & fitness sensors

For indoor sessions, where GPS is unavailable, Circloop uses your device's motion and fitness sensors (the pedometer) to estimate steps, distance, and pace. This data is read and processed entirely on your device and is never transmitted to ODAMIT or any third party. You can control access in Settings → Privacy & Security → Motion & Fitness.

Elevation data

When Circloop estimates the climbing on a route, your device downloads open elevation map tiles from the AWS Open Data terrain dataset (a public Amazon S3 bucket). These requests contain only the map-tile coordinates of the route's general area — no name, no identifier, no account, and no precise track. Like any internet request, it necessarily includes your IP address, which is handled by Amazon Web Services as the host of the public dataset. ODAMIT receives nothing.

Notifications

Activity reminders are local notifications scheduled entirely on your device. No push-notification service is used; nothing about your reminders leaves your phone.

Purchases

The optional one-time "Circloop Unlimited" purchase is processed by Apple through the App Store. We never see your payment details. Purchases are tied to your Apple Account by Apple, which is how restore-on-a-new-device works without a Circloop account.

Sharing (your choice)

If you actively share a route or activity (a GPX file or image card), you decide who receives it, through the iOS share sheet. The optional "Hide start & end when sharing" setting removes roughly the first and last 200 metres from shared exports, so they don't reveal where you live or work.

Apple Watch

Data flows between your iPhone and Apple Watch directly, device to device, through Apple's WatchConnectivity — never through a server.

What we do not do

If an optional iCloud sync feature is added in the future, it will use your personal iCloud account under Apple's privacy terms, remain within your Apple Account, and this policy will be updated first.

Your rights (GDPR / LGPD)

Because Circloop processes personal data (location, health, activity) exclusively on your device, and ODAMIT neither collects nor stores any of it, there is no personal data held by us to access, correct, export, or erase. Your data is under your direct control: view it in the app or Apple Health, export it via sharing, and erase it by deleting activities or the app.

For any privacy question, or to exercise rights under the EU General Data Protection Regulation (GDPR) or the Brazilian Lei Geral de Proteção de Dados (LGPD), contact feedback@circloop.app. You also have the right to lodge a complaint with a data protection supervisory authority.

Children

Circloop is a general-audience fitness app and does not knowingly collect any data from anyone — including children — because it collects no data at all.

Changes

If Circloop's data practices ever change, this policy will be updated here and the effective date revised. Material changes (such as the future iCloud sync option) will be announced in the app.
