Frequently Asked Questions

Where is my data stored?

On your iPhone. Lutara has no iCloud sync and no servers of its own, and we have no access to your health data. If you back up your iPhone, the backup may include Lutara's data. The app sends anonymous usage statistics (never health data), which you can turn off under Settings > Privacy; see the privacy policy.

How do I cancel my subscription?

Open the Settings app on your iPhone > tap your name at the top > Subscriptions > Lutara > Cancel Subscription. Cancellation takes effect at the end of the current billing period.

How do I request a refund?

Refunds for App Store purchases are handled by Apple. Visit reportaproblem.apple.com and sign in with the Apple ID used for the purchase.

How do I export my data?

Open Lutara, go to Settings > Export, and choose "Doctor PDF" or "Full Data Export (JSON)". The file can be saved, AirDropped, or sent by email.

How do I delete all my data?

Delete the Lutara app from your iPhone. Lutara has no iCloud sync, so nothing else is stored by us. Copies inside your own iPhone backups follow your backup settings.

Is Lutara a medical device?

No. Lutara is a wellness and journaling tool. It does not diagnose, treat, or prevent any condition. Always consult a qualified healthcare provider for medical questions.

Which devices are supported?

iPhone running iOS 26 or later. Apple Watch Series 8 or later is recommended (but not required) for wrist temperature data.

Still need help?

Email maotunko@gmail.com with a description of the issue and your iPhone model + iOS version (Settings > General > About). Screenshots help.
