Privacy Policy

The short version

Viola collects no data. There are no accounts, no analytics, no tracking, no ads, and no servers. Everything the app does happens on your device, and everything it saves stays on your device.

Camera

Viola uses the front camera to render lipstick shades on your face in real time, and the back camera to read colors from real-world objects when you use Scan a Shade. All camera processing happens locally using Apple's ARKit and on-device image processing. The camera feed is never recorded, stored, or transmitted anywhere — it is processed frame by frame and discarded.

Face data (TrueDepth API)

To place lipstick on your lips, Viola uses Apple's ARKit face tracking, which relies on the TrueDepth camera. The app receives a real-time face mesh (the geometry of your face) for the current camera frame and uses it only to position the lipstick overlay on your lips. This face data is processed entirely on your device, in memory, frame by frame, and is immediately discarded. Viola does not store, save, log, collect, or transmit face data; it is never sent to any server or third party, never used to identify or authenticate you, and never used for advertising, analytics, or building any profile. There is no retention — nothing about your face is kept after a frame is drawn. Because it never leaves your device, there is nothing to share, sell, or delete.

Photos and saved looks

When you capture a photo of a look, the image is saved inside Viola's own private app storage on your device — not to your camera roll, and not to any server. Saved looks and scanned colors are stored in a local database on your device. Deleting the app deletes all of it.

What we don't do

• No personal information is collected or requested.
• No analytics or crash-reporting SDKs that profile you.
• No third-party advertising or tracking of any kind.
• No network connection is required to use the app.

Changes

If a future version of Viola ever changes any of the above (for example, optional cloud sync), this policy will be updated first and the change will be clearly communicated in the app before anything takes effect.
