What AlignerPro is

AlignerPro helps clear aligner users track wear time, tray changes, progress photos, reminders, calendar entries, simple analytics and local backups. It does not provide dental or orthodontic advice, and it is not a replacement for guidance from your dentist or orthodontist.

What the app stores locally

The app stores its data in private storage on your Android device. This may include:

• Treatment setup details, including tray count, tray dates and active tray.
• Wear sessions, timer state, daily logs, notes and calendar entries.
• Reminder settings, theme settings and other app preferences.
• Progress photo records, saved photos and generated thumbnails.
• App lock settings, if you enable biometric or device lock protection.

Progress photos and tray data

Photos you take or import in AlignerPro are saved in the app's private storage so they can be organised by tray, date and photo angle. If you import a photo from your device gallery, the app saves its own copy for progress tracking. Your original gallery photo stays where it is.

Local backup and restore

When you export a local backup, the app creates a backup file containing the local app database, settings, timer preferences and progress photo files. You choose where that backup file is saved. AlignerPro does not upload that backup to its own server.

Restoring a backup replaces the local data on the device with the data from the selected backup file.

Whether data is sent to servers

AlignerPro does not use its own servers to store treatment data, timer history, reminders or progress photos. Core tracking data stays on your device unless you choose to export or send something yourself.

Optional actions may involve other services. For example, Premium purchases and restores use Google Play, and feedback emails are sent through your chosen email provider.

Website analytics and cookies

This website uses Google Analytics only if you choose Accept analytics in the cookie banner. Analytics is disabled until then, and rejecting analytics does not affect how the site works.

Google Analytics helps us understand which pages are viewed, whether guide pages are useful, and when people click through to Google Play or email support. It may also show aggregated browser, device and approximate location reporting from standard website data. We do not send form contents, email addresses, URL query strings or user-provided text to Google Analytics.

The website does not use Google Signals, advertising personalisation or user-provided data collection.

The Google Analytics property is configured to keep event data for 2 months and user data for 14 months. The user data retention period resets when someone returns to the site.

If you accept analytics, Google Analytics may set first-party cookies such as _ga and _ga_... to recognise repeat visits and keep session information. These cookies may last for up to 2 years unless you reject analytics, withdraw consent or clear them in your browser.

Your analytics choice is stored in your browser's local storage. You can change it at any time using Cookie settings in the footer. Rejecting analytics asks the browser to clear Google Analytics cookies for this site and prevents future analytics events from being sent.

Premium purchases

AlignerPro Premium is purchased through Google Play. When you view, buy or restore Premium, the app connects to Google Play to show pricing, complete the purchase and check whether your Google Play account owns the upgrade.

Payment details are handled by Google Play. AlignerPro does not receive or store your card details. The app stores a local Premium status on your device so Premium features can stay unlocked after purchase.

Feedback emails

If you email feedback@alignerpro.app, we receive the email address you send from and anything you include in the message. If you send feedback from inside the app, the email may include optional diagnostic details such as app version, build number, Android version and device model.

Crash and error reporting

No third-party crash reporting service is currently used. If that changes, this policy will be updated before crash or error data is collected.

Permissions

The app asks for permissions only when they are needed for app features:

• Camera: used to take progress photos.
• Photos and media: used when you choose to import progress photos from your device.
• Notifications: used for wear reminders, tray switch reminders, appointment reminders and timer status.
• Foreground service: used to keep the wear timer visible with a persistent timer notification while tracking is active.
• Biometric or device lock: used only if you enable app lock in settings.

Data deletion and clearing

You can clear app data inside AlignerPro from Settings, Data, Clear all data. This deletes local treatment data, trays, wear sessions, daily logs, appointments, reminders, settings and app-stored progress photos on that device.

You can also clear local data through Android: Settings > Apps > AlignerPro > Storage > Clear data. Uninstalling the app may remove local app data from the device. Backup ZIP files you created yourself are outside the app after export, so you need to delete those files wherever you saved them.

Clearing app data may remove the local Premium status cache, but it does not cancel or delete your Google Play purchase. Premium can be restored through Google Play if the same account still owns it.
