Activiz respects your privacy. This policy explains what data the app uses, why, and how it is protected.
Activiz connects to your Strava account to retrieve activity statistics and overlay them on a photo. The edited photo can then be exported.
Activiz requests access to your Strava activities (activity:read_all). This includes statistics such as distance, time, elevation, heart rate, and GPS coordinates for route display. This data is processed exclusively in your device's memory and never stored locally.
After signing in with Strava, the app receives an access token and refresh token. These are stored in your device's secure Keychain, accessible only when the device is unlocked. Tokens are not synced to iCloud and are device-bound.
Activiz reads one photo of your choice via the system photo picker. The app never stores photos itself — the export goes through the standard iOS share sheet, where you decide where the image goes.
Strava requires a secret key to renew access tokens. To prevent this key from being stored inside the app — where it could be extracted — token renewal is handled by an intermediate server (Cloudflare Worker) managed by the developer.
What the proxy does: forwards the app's request to Strava and returns the response.
What the proxy does not do: store or log tokens, user data, or any other information.
The connection to the proxy is encrypted (HTTPS) and requires an API key present only in the app.
| Party | Purpose | Privacy policy |
|---|---|---|
| Strava | Retrieve activity data via OAuth | strava.com/legal/privacy |
| Cloudflare | Hosting the token proxy | cloudflare.com/privacypolicy |
The app contains no analytics, advertisements, or other third-party SDKs.
You can sign out at any time: open the overlay editor, tap the settings icon, and choose "Sign out" at the bottom. Upon signing out, all stored tokens are immediately deleted from the Keychain. Since the app itself stores no user data, there is nothing further to delete.
To delete your Strava data or revoke app access: strava.com/settings/apps.
