Smile to Unlock Privacy Policy

Smile to Unlock is built privacy-first. Your face, your smiles, and your habits stay on your device. This policy explains, in plain language, exactly what that means - and it is written to match Smile to Unlock’s App Store privacy label line for line.

Camera and your face

Smile to Unlock uses the front camera for one thing: detecting a smile, right on your iPhone. Detection runs entirely on device. No image, video, or face data is ever uploaded or sent to us or to anyone else. Calibrating Smile to Unlock to your smile saves a sensitivity setting on your device, and it also saves a photo of that calibration smile, because keeping smile photos is on by default. iOS tells you this before the camera ever opens, in the camera permission prompt, and you can change it at any time in Settings under Keep your smile photos. Like every other smile photo it stays on your iPhone and you can delete it whenever you like.

Smile photos stay on your device

Smile to Unlock keeps a photo of each smile, the calibration one and every unlock after it, so you can look back on them. These photos are stored only on your iPhone, inside the app - they are never uploaded and never leave your phone, and they are never written to your photo library. Keeping them is on by default, and you can turn it off at any time in Settings. You can also remove any single photo, or delete them all at once, whenever you like. Deleting photos never affects your smile counts or your streak.

Smile films

Smile to Unlock can cut five or more of your saved smiles into a short film. The film is put together entirely on your iPhone - the photos are never uploaded and no server is involved. The finished video is written to the app’s own storage. If you tap save, and only then, it is added to your photo library, which is why iOS asks for permission to add to Photos at that moment. Smile to Unlock never reads your photo library, and it asks for no permission to do so. If you share a film, it goes wherever you send it, the same as any other video on your phone.

Screen Time and Family Controls

Smile to Unlock protects apps using Apple’s Screen Time (Family Controls) framework. You pick the apps with Apple’s own picker, and the list of what you protect, along with your unlock history, streaks, and goals, is stored only on your device. Nothing about which apps you protect or when you open them is sent anywhere.

No account, no analytics

There is no account to create and no sign-in. This version of Smile to Unlock sends no analytics - no usage events leave your device. If a future version adds anonymous analytics, this policy and the App Store privacy label will be updated first.

Subscriptions

Premium subscriptions are processed by Apple and by RevenueCat, the service we use to manage subscriptions. When you buy or restore Premium, RevenueCat receives the purchase from Apple and assigns an anonymous identifier so your subscription can be restored on a new device or after reinstalling. This is used only to know whether your subscription is active. It is not linked to your name, it is not used to track you, and we never receive your payment details.

Children

Smile to Unlock does not collect data from anyone, including children.
