Sleep Worlds is an app by Calming Audio LLC (“we”, “us”). This policy explains what information the app uses, why, and the choices you have.
The short version
- You can use Sleep Worlds without an account. If you do, everything stays on your phone.
- If you create an account, we keep your email address and your sleep progress so you can get it back on a new phone.
- Purchases are handled by Apple. We never see your card or payment details.
- We don’t show ads, we don’t sell your information, and we don’t track you across other apps or websites.
Information that stays on your phone
Your worlds, settings, alarms, sleep timer, the nights you’ve spent in each world, your stamps and postcards are saved on your device. We can’t see them unless you create an account.
If you create an account
Accounts are optional. If you sign in with your email address or with Apple, we store:
- Your email address (or the private relay address Apple gives us if you choose “Hide My Email”), so you can sign in.
- Your progress: which nights you completed, which world you slept in, how long each session lasted, and the stamps, postcards and rewards you’ve earned. This lets you keep your progress on a new phone.
This information is stored by our account provider, Supabase, on our behalf.
Purchases
Subscriptions and purchases are processed by Apple. We never receive your payment details. To know what you’ve bought and unlock it on your devices, we use RevenueCat, which receives your purchase history and an app user ID. If you’re signed in, that ID is your Sleep Worlds account ID, so your purchases follow your account.
Notifications and alarms
If you turn on alarms or bedtime reminders, they are scheduled on your phone. We don’t receive them.
Apple Health
Apple Health is optional and off until you turn it on in Settings → Apple Health. If you do:
- Sleep Worlds saves your breathing before sleep to Apple Health as Mindful Minutes.
- Sleep Worlds reads your sleep from Apple Health (recorded by an Apple Watch or your iPhone) to show how long you slept on the morning card.
Your Health data stays on your phone. We never send it to our servers, our account provider, RevenueCat or anyone else, and we never use it for advertising or marketing. You can change what Sleep Worlds can see or save at any time in the Health app under Sharing → Apps → Sleep Worlds.
Microphone
Sleep Worlds never records audio. iOS may show a microphone notice because an audio library inside the app contains microphone code. The app never turns the microphone on.
Services we use
| Service | What it does for us | What it receives |
|---|---|---|
| Apple (App Store) | Payments and subscriptions | Your purchases, under Apple’s privacy policy |
| Supabase | Accounts and saved progress | Email address and progress, only if you create an account |
| RevenueCat | Knowing what you’ve bought | Purchase history and an app user ID |
We don’t sell or share your information with anyone else, and we don’t use it for advertising.
Keeping and deleting your information
We keep your account information until you delete your account. You can delete it at any time in the app under Settings → Account → Delete account. This permanently removes your email address and saved progress from our account system. If you signed in with Apple, it also removes Sleep Worlds’ access to your Apple ID.
To ask us to delete purchase records held by RevenueCat, or for any other privacy request, contact us at the address below.
Children
Sleep Worlds is not directed to children under 13, and we don’t knowingly collect personal information from them.
Changes
If we change this policy, we’ll update the date at the top and, for significant changes, tell you in the app.
