Privacy policy

Updated October 2026

Öi is a hide-and-seek game for iPhone provided by MD Apps Ltd.

Information used by the app

Öi works offline and does not require an account. The app does not send personal information, gameplay activity or motion readings to us. It contains no advertising, tracking or third-party analytics services.

The app saves your difficulty, music and hide-screen preferences, along with whether you have seen the tutorial, on your device. These settings are used to remember your choices. Öi does not send them to us or provide its own cloud-sync service.

Motion and sound

Öi uses the iPhone’s motion sensors to recognise when the phone is resting still and when it is picked up. Motion readings are processed on the device during gameplay and are not transmitted to us or stored as a motion history.

The app plays bundled music and character sounds. It does not use the microphone to listen or record audio, and it does not access your camera, photos, contacts or location.

Children

The same offline behaviour applies to everyone who plays Öi. The app does not ask children to provide personal information and contains no account registration, chat or advertising. A parent or guardian can contact us with support or privacy questions.

Contacting support

If you contact us through the support form, we receive your name (if you give it), your email address and your message. We use them only to reply to your enquiry. Messages are delivered to our inbox by our email provider, Resend, separately from the app. You can contact us to request deletion of support correspondence.

Apple services and this website

Apple handles App Store downloads, purchases and any device diagnostics you choose to share under Apple’s own privacy settings and policies. This is separate from Öi’s offline gameplay.

This policy covers the Öi app. Visiting this website is a separate interaction. The site is hosted by Vercel, and the video on the home page is played by Vimeo; these providers may process technical information, such as your IP address, when you visit. The site itself sets no cookies and uses no analytics.

Changes and contact

We will update this page if the app’s privacy practices change.

For support or privacy questions, use the form on our support page. This is the shared support for Öi and Days, both published by MD Apps Ltd.
