Privacy policy

Last updated 12 October 2026

The app

We collect no data from you. The Daily Neutrino sends nothing to us or to anyone else.

• Everything is calculated on your phone, for the app and for the widgets. The app makes no network requests for it.
• Your settings, including which planets you get notifications for, stay on your phone.
• Your phone schedules the notifications. No server sends them.
• There are no analytics, no advertising and no tracking.

The purchase and the trial

Apple handles the purchase. We don't receive your name, email address or payment details. Apple's privacy policy covers them: apple.com/legal/privacy.

You can try notifications and widgets free for 14 days. The trial period begins when you download the app. To know when it ends, the app reads that date from the App Store's record on your phone. The date stays on your phone.

This website

This website uses no cookies and no analytics, and loads nothing from other sites. Cloudflare hosts it, and processes your IP address and the pages you request to deliver them and to protect the site from attacks. See Cloudflare's privacy policy.

If you email us

We use your email address and what you write only to answer you, and delete them once we no longer need them for that.

Your rights

Under the GDPR you can ask what data we hold about you, and have it corrected or deleted. You can also complain to a data protection authority. As the app collects nothing, the only data we could hold is an email you sent us.
