Privacy Policy

Last updated: November 13, 2026

DualMirror is a makeup mirror for iPhone. This policy explains what data the app uses and what happens to it.

In short: the camera image is analyzed live on your iPhone, without being saved or sent. DualMirror has no user account, no advertising and no analytics, and sends no data to the publisher or to any third party.

Data controller

Omniscient Sàrl, c/o Fondation EPFL Innovation Park, EPFL Innovation Park, Bâtiment C, 1015 Lausanne, Switzerland (UID CHE-272.830.651). Contact: contact@omniscient.swiss.

This policy follows the Swiss Federal Act on Data Protection (FADP) and, for people who live in the European Union, the General Data Protection Regulation (GDPR).

The camera and your face

• The mirror shows the image from the front camera, or from the under-display camera on iPhone Duo.
• To apply the virtual makeup, the app locates the outline of the lips, eyes and cheeks in real time using Apple’s Vision framework. This processing takes place entirely on your iPhone, frame by frame.
• No photo, no video and no data about your face is saved, on the device or anywhere else. Nothing is sent to the publisher or to any third party.
• The detected points are used only to place the makeup on your reflection. They are not used to identify you. They stay only in the app’s memory, just long enough to display the image: each new frame replaces the previous points, and they disappear as soon as your face leaves the frame or the app closes.
• You can remove camera access at any time in Settings ▸ DualMirror ▸ Camera.

Motion sensors

The app reads the hinge angle of iPhone Duo and the motion sensors to tell whether the device is set down or held in your hand, and to adapt the layout. These readings are used on the spot, then forgotten.

What stays on your iPhone

• Your settings: palette placement, framing, fill light.
• The looks you save: their name, shades, intensities and strokes. These are makeup settings, never images.

This data stays in the app’s own storage space on your iPhone. It may be included in your device backups (iCloud or computer), depending on your own iOS settings. To erase it, delete your looks in the app or delete the app.

Subscription and payment

The DualMirror+ subscription is sold and billed by Apple, on the App Store. Payment, renewal, cancellation and refunds are handled by Apple, under its own privacy policy: https://www.apple.com/legal/privacy/

The publisher does not receive your name, your email address or your payment details. The app checks your subscription directly on your iPhone, using information signed by the App Store; this information is not passed on to the publisher. Apple provides the publisher with aggregated sales reports (number of subscriptions, countries, revenue), which do not identify you.

Analytics and crash reports

DualMirror includes no analytics, advertising or tracking tools. If you have agreed to share your data with app developers (Settings ▸ Privacy & Security ▸ Analytics & Improvements), Apple may send the publisher crash reports and anonymized usage statistics. You can change this choice at any time in iOS Settings.

The getdualmirror.app website

The getdualmirror.app website presents the support page, this policy and the terms of use. It is hosted in Switzerland, on an Infomaniak Network SA server that we administer. It sets no cookies, does not measure its audience and loads nothing from any other website: even its font comes from our server.

Like any website, it receives your device’s IP address in order to send it the pages. It keeps no log of visits: only server errors are recorded, with the IP address concerned, in a technical log that keeps only the latest entries. If you live in the European Union, the legal basis for this processing is our legitimate interest in running the website and protecting it (Article 6(1)(f) GDPR).

If you write to us

If you contact support, your email address and your message are used only to reply to you. They are hosted in Switzerland by our email provider, Infomaniak Network SA, which processes them on our behalf. We keep them for as long as it takes to handle your request, and at most three years after our last exchange, then we delete them. If you live in the European Union, the legal basis for this processing is our legitimate interest in answering the requests sent to us (Article 6(1)(f) GDPR).

Your rights

The FADP and the GDPR allow you to request access to your data, its correction or its erasure, to obtain a copy of it in a common format (portability) and to object to its processing. The GDPR also allows you to request that its processing be restricted.

The app sends no data to the publisher, so most of these rights are exercised directly on your iPhone (delete your looks, remove camera access, delete the app). For any other question or request, in particular about your messages: contact@omniscient.swiss.

If you believe your rights are not being respected, you can contact the Swiss Federal Data Protection and Information Commissioner (FDPIC): https://www.edoeb.admin.ch/en

If you live in the European Union, you can also lodge a complaint with the data protection authority of your country, in France the CNIL: https://www.cnil.fr/en

Children

DualMirror collects no data, including from minors.
