Privacy Policy
Calmo – Bedtime Stories for Kids · Last updated October 28, 2026
In short
- No accounts, and the app never asks for a name, email address, photo or location.
- No ads, and no advertising identifiers.
- We don't sell or share information for advertising.
- We collect only anonymous app-usage statistics and crash reports, through Google Firebase, to keep the app working well.
This policy explains what information the Calmo app ("Calmo", "we", "us") handles, why, and the choices you have. Calmo is made for families and is designed to be used by children with a parent or guardian.
1. Information kept only on your device
Some information is stored only on your phone or tablet so the app can work. It is not sent to us:
- your favourite stories, your place in the last story you played, and your settings (such as the sleep timer)
- stories and videos saved for offline listening
- whether you have an active Calmo Premium subscription
Deleting the app removes this information.
2. Anonymous usage statistics (Firebase Analytics)
We use Google Firebase Analytics to understand how the app is used, for example which stories are enjoyed and whether a screen is confusing. It records:
- app activity, such as screens opened, stories and videos played, favourites, sleep-timer use, and subscription screen visits and purchase results
- the answers chosen during the welcome questions: the child's age range (for example "3–5 years"), the kind of stories they like, and the reason for choosing Calmo
- technical details: device model, operating system version, app version, language, approximate country or region, and a random app-instance identifier created by Firebase
This information doesn't identify you or your child. We use it only to operate and improve Calmo. It is not used for advertising, profiling or tracking across other apps or websites.
3. Crash reports (Firebase Crashlytics)
If the app crashes, Firebase Crashlytics sends a crash report containing technical details (what went wrong, the device model, operating system and app version, and the app-instance identifier) so we can fix the problem.
4. Purchases
Calmo Premium is bought through Apple's App Store. Apple processes the payment; we never see or store your payment details, name or Apple ID. The app receives only the purchase status (which plan, and whether it is active) from Apple.
5. Delivering stories
Story audio and videos are streamed and downloaded from Google Firebase Storage. As with any internet download, Google's servers receive your device's IP address to deliver the files.
6. Children's privacy
We do not knowingly collect personal information from children. Calmo has no accounts, chat or sharing features, and shows no ads. The analytics described above are anonymous and are used only to run and improve the app. If you believe a child has sent us personal information, contact us and we will delete it.
7. Who processes the information
| Provider | Purpose | Their policy |
|---|---|---|
| Google Firebase (Analytics, Crashlytics, Storage) | Usage statistics, crash reports, delivering story files | firebase.google.com/support/privacy |
| Apple (App Store) | Subscriptions and payments | apple.com/legal/privacy |
We share information only with these providers, so they can deliver these services, or when the law requires it. Their servers may be located outside your country.
8. How long information is kept
Firebase keeps app-instance analytics data for a limited period (at most 14 months) and crash reports for 90 days, after which they are deleted automatically.
9. Your choices
- You can delete the app at any time to remove all information stored on the device.
- You can ask us any question about your information, or ask us to delete it, by emailing the address below.
10. Changes to this policy
If we change this policy, we'll post the new version on this page with a new date.
