What applies
Your use of Cosmosono is governed by Apple’s standard End User License Agreement (EULA). This page sums up, in plain words, what applies when you buy Cosmosono Plus. Where they differ, the EULA prevails.
Free and Plus
Cosmosono is free to download and has no ads. Radio school, chapters 1–3 and the first signal of chapter 4, “Radio pals” (part 1), the daily signal, the first chapter of every season, and Zen for listening, falling asleep (up to 20 minutes) and breathing are free. Cosmosono Plus unlocks everything else: the whole journey with all its chapters (at least 15), “Radio pals” part 2, every chapter of each season (while it runs), your own daily puzzle, Sunday and special-day puzzles, the archive, all of Zen (including the gentle alarm), the sound worlds and unlimited hints. Seasons are open for a limited time and then close for everyone, including Plus; the stars and rewards you collected stay. The season “Winter at Halley’s” is open until 31 January 2027. The app shows exactly what Plus includes before you buy.
Ways to buy and prices
- Monthly and yearly subscription – the yearly one with a 1-week free trial, when offered.
- One-time purchase – Plus forever, no subscription and no renewal.
You see the prices in your currency in the App Store and in the app before you buy. They include the taxes shown there.
Payment
All purchases are made through the App Store and paid with your Apple Account. We never receive payment details.
Term, renewal and cancellation
- A subscription renews automatically for the same period unless you cancel at least 24 hours before it ends. The renewal is charged within the last 24 hours before it ends.
- You can cancel at any time in your device’s Settings under your name → Subscriptions. Plus stays active until the end of the paid period.
- If you cancel at least 24 hours before the end of a free trial, you are not charged. Any unused part of a free trial ends when you buy a subscription.
- If you buy Plus Forever while a subscription is running, cancel the subscription yourself – the app reminds you.
Withdrawal and refunds
Purchases in the App Store are subject to Apple’s terms, including the statutory right of withdrawal for consumers in the EU. To request a refund, go to reportaproblem.apple.com.
Family Sharing and restoring purchases
Plus can be shared with your family through Family Sharing. On a new device, get Plus back in the app with “Restore Purchases” – using the same Apple Account.
Changes
We keep developing Cosmosono. Content may change with updates; the app always shows what Plus includes before you buy. If these terms change, we update this page and the date at the top.
Privacy and help
How the app handles data is described in the app’s privacy policy. For questions, use the contact form.
