Your LUN subscription is handled by the App Store. To view, change, or cancel it, open your device Settings, tap your name, then Subscriptions, and select LUN. Cancelling stops the next renewal; you keep access until the end of the period you already paid for.

You can permanently delete your account and all associated data from inside the app, in your account settings. If you cannot access the app, email us at contato@heylun.app from your registered address and we will process the deletion for you.

Many setup and usage questions — irregular cycles, hormonal birth control, privacy, cancelling — are answered on our homepage FAQ.

LUN is an educational wellness app and cannot answer personal medical questions or handle emergencies. For anything concerning your health, please consult a qualified healthcare professional. In an emergency, contact your local emergency services.
