BeautySkIn

Privacy Policy

Last updated: 5 August 2026

BeautySkIn was designed to work without an account and without a server. Your makeup data never leaves your phone. Here is the detail, in plain language.

Who is responsible

The app is published by Nathalie Scharf (AI-Creativ), an independent sole trader based in Martinique, France.

The camera

The app uses the camera to show makeup on your face in real time, and to pick up the colour of a garment or a product when you ask it to.

No image is ever sent anywhere. Face detection runs entirely on your device, through a component embedded in the app that works without an internet connection. The video stream is never recorded, transmitted, or analysed anywhere other than on your phone. The skin scan is fully local as well.

Your data stays on your device

Your makeup kit, your profile, your saved looks and your settings are stored only in your phone's local storage. There is no copy on any server.

• No account to create, no email address requested.
• No data sold or shared, and no personal data passed to a third party.
• No advertising tracker. An anonymous usage measurement exists, described below, and you can refuse it.
• No location data requested or stored.

The only external service

A single optional feature queries an external service, and no personal data is transmitted.

• Barcode scanning queries the free public database Open Beauty Facts to find a product name from its barcode. Only the barcode number is sent, nothing else.

Anonymous usage measurement

To find out which screens cause trouble and which features nobody uses, the app sends technical events. They are hosted in Europe, in Frankfurt, by the PostHog service.

What is sent, and nothing else:

• the name of the screen shown, for example “the first story”;
• the label of the button tapped and the screen it sits on, plus the list of buttons shown on that screen. This is what makes it possible to spot a feature nobody uses and remove it;
• incidents, such as a refused camera;
• a random number that says nothing about you, used only to link the steps of a single visit.

What is never sent: no photo, no makeup kit, no profile, no skin tone, no first name, no address, no location. What you type into a field is not sent either, and button labels are cleaned of anything resembling an e-mail address or a run of digits.

You can refuse this measurement on the “Me” screen, in the privacy section. After that nothing is sent at all, not even the fact that you refused.

Permissions requested

The app requests only two permissions:

• Camera: for makeup try-on and colour capture, locally.
• Internet: only for the barcode lookup described above.

No location, storage, contacts, microphone, or advertising identifier permission.

Deleting your data

Since your data lives only on your phone, you erase all of it by uninstalling the app, or by clearing the app's data in your device settings. No request to us is needed, and we hold nothing to delete.

Children

The app is intended for an adult audience and does not target children under 13.

Changes

If a future version of the app changes how your data is handled, this page will be updated and the date at the top changed accordingly.
