Privacy policy for the Cosmosono app
As of 13 November 2026 · Deutsche Fassung
In short
Cosmosono collects no personal data. The app works fully offline. If iCloud is turned on on your device, your progress and your solar system are kept in sync between your devices through your own iCloud – we have no access to it. No accounts, no ads, no tracking, no analytics.

What the app processes
- Progress (solved puzzles, stars, times, hints, streak, awards, the start day of your journey calendar): stored on your device and, if iCloud is on, in your own iCloud (Apple’s iCloud key-value storage) so it reaches your other devices. We run no server and cannot see this data. Apple’s privacy policy applies to iCloud. You can turn iCloud off for Cosmosono in your device settings.
- Settings (sound, vibration, tempo, appearance, language): only on each device – except your solar system (sun, planets, orbits, glows, saved systems, including names you gave them), which is synced through your own iCloud like your progress, when iCloud is on.
- Widgets: the app stores pictures of your solar system and a few numbers (stars, streak, daily signal) in a space on your device that only the Cosmosono widgets read. This data never leaves your device.
- Daily reminder (only if you turn it on): the app schedules one notification a day on your device at the time you chose, and with Plus one more when your next radio window opens. iOS asks for your permission once. Nothing is sent – neither to us nor to anyone else – and you can turn the reminder off at any time in the app or in the iOS settings.
- Zen alarm (with Plus, only if you set it): the app sets an alarm on your device through Apple’s alarm feature (AlarmKit). iOS asks for your permission once. The alarm time stays on the device; nothing is sent.
- Zen with the screen locked: so the sleep timer keeps running, Zen keeps playing in the background and shows the time left as a Live Activity on the Lock Screen. This happens on the device only.
- Photos: the app has no read access to your photos. Only when you tap “Save as Live Photo” does iOS ask whether Cosmosono may add a picture to your photo library. Only the picture of your solar system that you chose is saved.
- Purchases (“Cosmosono Plus” as a monthly or yearly subscription or a one-time purchase): handled entirely by Apple through the App Store. The app only learns whether a valid purchase exists. We receive no payment data and no identity. Apple’s privacy policy applies.
- Sharing: when you share a result or your solar system, the app you pick receives – depending on what you share – a short text (number, stars, time, hints, streak), a picture or a short film of your solar system, and a link to our website. What happens there is outside our responsibility.
- Sound and haptics are generated on the device only and never recorded.
- Rating: at most once per version, the app may ask for a rating through Apple’s own prompt. We only see ratings the way the App Store shows them publicly.
- Feedback: “Send feedback or report a bug” opens our contact form in the browser. App version, device model, system version and app language sit in the part of the address after “#”. That part is not sent to our server when the page opens; the page only fills the details into the form so we can find a bug. Only what you send yourself is sent; you can delete these details beforehand. We also store the message without name and email in a non-public project on GitHub to sort feedback; details in the website’s privacy policy.
What the app does not do
- no internet connection for the game itself (only Apple services: App Store and iCloud sync; links in Settings open this website)
- no ad networks, no third-party analytics, tracking or crash services
- no access to contacts, location, microphone, camera or motion sensors; no read access to photos (see above: adding only, on request)
Your rights
As we process no personal data, we hold no data we could disclose or delete. You can delete your progress at any time in the app under Settings → “Reset progress”; this also clears the iCloud copy. Your solar system stays. You have the right to file a complaint with a data protection authority.
For this website, the privacy policy of Orthonormal Studio applies.
Children
Cosmosono is made for the whole family, children included. Because the app collects no personal data, shows no ads and uses no analytics services, no data is collected from children either. Purchases go through Apple and can be protected with Ask to Buy in Family Sharing and with Screen Time. The feedback form opens in the browser and sends only what someone submits themselves.
Changes
If the app gains features that process data, we will update this policy beforehand.
