Summary
Atria does not collect, sell or upload your personal health and fitness data in this release. The app has no Atria account, cloud database, advertising SDK or third-party analytics tracker. Data leaves the app only when you explicitly use an iOS share or export action.
This policy describes the information Atria processes locally, the iOS permissions it may request, the optional research bundle, and the other actions that can move data outside the app at your direction.
Information processed on your device
Depending on the features you use and the data your compatible strap makes available, Atria may process and store:
- Your nickname, profile settings and training preferences.
- Bluetooth connection information, strap identifiers and battery status.
- Sensor readings such as heart rate, beat intervals and supported motion or physiological signals.
- Derived personal-fitness information such as resting heart rate, HRV, recovery, strain, sleep summaries, workout summaries and trends.
- Journal entries, confirmations, edits and other context you add.
- Local diagnostics needed to explain data quality, confidence and connection behavior.
This information is stored in Atria's app container on your iPhone. Atria's developer cannot remotely view it.
No account, advertising or tracking
Atria does not require an account and does not operate a user-facing backend for your history. It does not sell data, build advertising profiles, use cross-app tracking or include advertising. It does not upload your profile, strap readings, metrics, journal entries or diagnostics to the developer.
The App Store and iOS may process purchase, installation and system diagnostic information under Apple's own policies. Atria does not receive your payment-card details.
Optional research bundle preparation
In Settings you can choose Share anonymously with developers. This does not enable an upload service. In the current release it only permits Atria to prepare a local, inspectable research bundle on your iPhone; every Atria feature works without it.
The Agree control stays locked until you open the in-app inspector and review a real bundle. That preview shows its compressed size, digest, and a sample of the allowlisted fields.
What the local bundle can contain
The bundle is built from an explicit allowlist. It may include heart-rate and heart-rate-variability series, sleep summaries, user-confirmed activity type, timestamp-shifted motion features, daily scores, journal answers stored as structured values, and coarse bands for age, weight, height and sex.
What the bundle excludes
The bundle excludes your name, email, device or strap names, exact birth date, exact weight or height, location, timezone, and free-text you type. Absolute calendar dates are replaced with seconds and day indexes relative to the first day in the bundle. It uses a random pseudonym not connected to your Apple ID or device identifier.
How it can leave your phone
This release has no Atria upload transport or developer endpoint. A consented local bundle can be prepared at most once per day at the time you select, but remains in Atria's local outbox. It leaves the phone only if you explicitly choose a recipient through the iOS share sheet. That recipient's privacy policy then applies. Turning sharing off clears the local outbox and destroys the pseudonym used for later bundles.
Apple permissions and third-party services
Bluetooth
Atria uses Bluetooth to discover and communicate directly with a compatible strap nearby. This can include the strap's Bluetooth identifier, connection state, battery state, and sensor data. Atria processes it locally.
Apple Health
If you enable supported Apple Health features, iOS presents a system permission sheet. Atria reads or writes only the health categories you approve and uses them only for the feature described in the app. You can change this access at any time in iOS Settings or the Health app. Atria does not send Apple Health data to the developer.
Location, motion, camera and photos
For an outdoor workout you start, Atria may request precise location to record its route, distance and pace. It may use Motion & Fitness data to classify movement and provide activity context. If you choose to create or share a visual card, it may request camera or photo-library access for the image you select. These inputs are processed on your device and are not uploaded to Atria.
Maps
When you view a route on a map, Atria uses Apple MapKit. Map tiles and related requests are provided by Apple and handled under Apple's privacy policy.
Notifications and background activity
If enabled, iOS may allow Atria to deliver local reminders or continue permitted Bluetooth work in the background. These permissions do not create an Atria cloud account.
Exports, deletion and your control
Data can leave Atria when you take an action that uses another app or service—for example, exporting a backup, sharing a file, writing an authorized item to Apple Health, including information in a support message, or selecting a recipient for an anonymized research bundle. Once shared, that destination's privacy policy applies.
You can remove Atria's local data using controls available in the app or by deleting the app from your iPhone. Deleting the app does not remove copies you previously exported or information managed independently by Apple.
Health and safety
Atria is a personal fitness and research companion, not a medical device. Its metrics can be incomplete, estimated or affected by hardware and signal quality. Do not use Atria for diagnosis, treatment or safety-critical decisions.
Atria is not directed to children under 13. If you believe a child has provided information to the developer in a support request, contact us so it can be deleted.
Changes to this policy
If Atria's data practices change, this policy and its effective date will be updated. Any future release that adds an Atria upload service will describe the recipient, purpose, retention and deletion process here before that transport is enabled.
