Calmhum Privacy Policy

Calmhum has no account, no ads and no server of its own. Every sound is made on your device while you listen. Nothing is downloaded, and nothing you enter (your journal, your sound choices) is sent to the developer. The only data that leaves the app is app usage statistics, described in the "App usage statistics" section below, and you can turn that off.

• Account: No sign-up, no login.
• What stays on your device: The app keeps the following on your phone or tablet only. None of it is sent to the developer.
  • Your sound settings: which sounds are on, each sound's volume, the overall volume, the tone you picked, your timer choice and the vibration setting.
  • Your journal: for each day, how noticeable the ringing was and how you slept (two scores from 0 to 10), and when you last changed them.
  • Whether you accepted the notice shown the first time you open the app.
  • How many times you have started playback. This is used only to ask once for a store rating.
  • The result and time of the last check with the App Store or Google Play, so sounds keep playing when you are offline.
  • The date you first opened the app, used to run the free week.
• Device backups and moving to a new phone
  • Android: Calmhum turns off Android backup, so nothing the app stores is included in Google cloud backup. One exception: the date you first opened the app is also saved on your phone with Google Play services (Block Store), with cloud backup turned off, so the free week does not restart after reinstalling. Android may copy that date when you move directly from an old phone to a new one. It is not sent to the developer.
  • iPhone and iPad: your journal is marked to be left out of device backups (iCloud Backup and computer backups). The date you first opened the app is kept in the device keychain as "this device only": it is not synced through iCloud Keychain and does not move to a new device. Your other app settings listed above (sound settings, the first-launch notice, the playback count and the last store check) are saved like ordinary app settings, so they can be included in your own iCloud Backup or computer backup and restored from it. That backup belongs to your Apple Account; it is not sent to the developer.
  • To move your journal to a new phone, share it as a PDF or CSV file (see below).
• Purchases: Monthly and yearly subscriptions and the one-time Lifetime purchase are sold only through the App Store or Google Play. Payment details are handled by the store; the app and the developer never receive them. To check whether you have an active plan, the app asks the store on your device. Cancellations and refunds are handled in the store's subscription settings.
• Rating request: The app may ask once for a rating through the store's built-in rating prompt. What you choose there goes to the store, not to the developer.
• Sharing your journal: If you choose to share your journal as a PDF or CSV file, the file goes to the app you pick (for example, Mail). Calmhum creates the file in a temporary folder. On iPhone and iPad it is deleted when the share sheet closes; on Android it is deleted the next time Calmhum starts. Any leftover file is also removed when the app starts.
• Lock screen and notifications: Playback controls on the lock screen and in notifications are handled by your device. Nothing is sent anywhere.
• App usage statistics: Starting with version 1.0.1, Calmhum uses Google Analytics for Firebase to learn which screens and features are used, so the developer can improve the app. What is collected: which screens you open and which features you use (for example that you started playback, saved a tone, set the timer or saved a journal entry), the time spent on a screen, whether the app is in the free period or has a plan, a random app-instance identifier created by Google Analytics for this installation, your device model, operating system version and language, your approximate location (country or region, derived by Google from the network address and not stored as an address), and in-app purchase and subscription events including the product and price. What is never collected: your journal scores, the tone you picked, your sound settings, your name or contact details, and the advertising identifier (Calmhum does not use it). This data is not used for advertising and is not linked to your identity. It is sent to Google and stored on Google's servers under Google's privacy policy (https://policies.google.com/privacy); Google keeps the detailed event data for 14 months.
  • Your choice: In the European Economic Area, Switzerland and places where Calmhum cannot tell where you are, the app asks you once before collecting anything, and collects only if you choose "Allow". Everywhere else, collection is on by default. You can turn it on or off at any time in Settings › Privacy › "Send app usage statistics". The app works the same either way.
• Third parties: The developer does not sell personal data. Apart from Google Analytics for Firebase described above, Calmhum contains no third-party analytics, advertising or crash-reporting code. Purchases, the rating prompt and the free-week date use Apple's and Google's own tools (Google Play Billing, Google Play In-App Review and Google Play services Block Store on Android; StoreKit and the device keychain on iPhone and iPad); Apple and Google handle that information under their own privacy policies.
• Deleting your information: You can delete your whole journal in Settings › Delete journal. Uninstalling the app removes everything Calmhum stores on your device and resets the app-instance identifier used for usage statistics, with one exception: the date you first opened the app stays in the device keychain on iPhone and iPad, and in Google Play services (Block Store) on Android phones that have Google backup turned on, so the free week does not restart after reinstalling. It is not sent to the developer. Copies in your own device backups follow the backups you keep.
• Children: Calmhum is not directed to children under 13.
