Privacy Policy

Effective July 2026

Solen is a personal training and coaching app. This policy explains what data Solen handles and why. Your personal training content is stored on your device. Relevant context is sent when you use AI coaching, and limited operational records support access and usage controls.

Data stored on your device

Your profile, training program, workout logs, check-ins, body measurements, progress photos, and meal logs are stored locally on your device. Solen does not keep a server-side copy of that complete training history. Until user-controlled transfer is available, this data cannot be restored after the app is deleted or the device is lost or replaced.

Apple Health

If you choose to connect Apple Health, Solen requests read-only access to the health and activity categories shown in Apple’s permission sheet. Imported values are stored with your other on-device measurements. They may be included in the relevant context sent to our AI provider when you use AI coaching, as described below. Solen does not write to Apple Health. You can change access at any time in the Health app or iOS Settings.

Operational service records

After you consent, Solen creates an anonymous Firebase service login rather than asking for a named account. The login is required to secure AI requests, access controls, usage limits, privacy requests, and notification delivery. Our service keeps limited records linked to that identifier, including coaching usage counters, access level, invitation redemption, and—only if you enable notifications—a Firebase Cloud Messaging device token and entitlement-tier notification group. These records are separate from the complete training history stored on your device.

AI coaching

To generate coaching, Solen sends relevant context—your goals, training history, and metrics such as weight, body fat, recovery, and sleep, along with check-in notes, meal notes, or chat messages you choose to enter—to our AI provider, OpenAI. This data is processed to serve you and is not used to build advertising profiles. OpenAI may retain API inputs and outputs for abuse monitoring for up to 30 days. Progress photos are not sent unless a separate photo-analysis feature asks for and receives your explicit consent.

Analytics and diagnostics

If you opt in, Solen uses Google Firebase Analytics and Crashlytics to collect app usage and crash-diagnostic data so we can fix problems and improve the app. On this website, Firebase Analytics loads only after you choose “Allow analytics” and records visits, page interactions, App Store interest, support actions, and broad scroll depth. We do not use advertising cookies or track you across other apps or websites. You can change the website choice at any time using Analytics settings in the footer.

Notifications

If you choose to enable notifications, Apple Push Notification service and Google Firebase Cloud Messaging process an app-specific device token plus technical information needed for delivery, such as app version, device model, operating-system version, language, and time zone. Solen links the Firebase token to your anonymous service ID and current access tier so we can send relevant service and coaching notifications to the correct group. We do not use notification data for advertising or cross-app tracking. You can turn Coaching Presence off in Solen or disable notifications in iOS Settings at any time.

Withdrawing consent

You can withdraw AI consent in Settings → Data & Privacy. AI coaching, proactive messages, photo analysis, push-token registration, and optional analytics stop, the device is removed from Solen's notification groups, and the app returns to the consent screen. Your local training history is preserved. You can separately delete your account and data using the deletion control.

Accessing your data

You can request a copy of the data Solen's service holds about your anonymous account in Settings → Data & Privacy. We collect the delivery email you provide only to verify, communicate about, and fulfill that request. We respond within 30 days and remove the request record after fulfillment.

What we don’t do

We do not sell your data. We do not track you across other companies’ apps or websites, and Solen uses no advertising identifiers.

Deleting your data

You can use Settings → Data & Privacy → Delete account & data. After Solen confirms that the request was recorded, the app removes your on-device profile, plans, history, measurements, photos, and meals, unregisters the device from notifications, and returns to a fresh state. We delete the anonymous Firebase account and operational records described above no later than seven days after the request. See the account deletion instructions.

Age requirement

You must be at least 18 years old to use Solen. It is not directed to children, and we do not knowingly collect their data.
