Privacy policy
In short: Cascade does not collect, send or sell any data. The microphone is used only to count your catches; the sound is analysed live on your phone and is never recorded or stored.
Who is responsible
Cascade: Juggling Tracker is made by Mariusz Patek. Contact: m.patek002@gmail.com.
Microphone
The app asks for microphone access to count catches while you juggle. Sound is processed in your phone's memory in real time: the app only turns it into loudness levels and uses them to recognise catches and drops. No recording is made, and nothing is saved to storage or sent anywhere. The microphone is active only on the training screen and in the calibration wizard. You can decline it and enter results by hand.
Training data
Your sessions, attempts, records, custom tricks and calibration settings are stored on your phone. The app has no user accounts or server and does not connect to the internet. The developer has no access to your data.
Sharing
Record and progress images are created on your phone and go only where you send them through the system share sheet. The app never sends them anywhere by itself.
Backup and reminders
A backup file is created only when you export it, and goes only where you send it through the system share sheet. Import reads only the file you pick yourself. Your training data can also be included in Android's own backup, which your phone makes to your Google account if you have it turned on. This brings your history back on a new phone or after reinstalling the app. The backup is managed by Google, and the developer has no access to it. You can turn it off in your phone's backup settings. Training reminders are scheduled by your phone, without the internet. For this the app asks for permission to show notifications, and it starts after a phone restart only so that reminders are not lost.
Contact, ratings and updates
The "Contact the author" button opens your email app with a ready draft: the app version, phone model, Android version and the kinds of recent app errors (without their details and without your data). Nothing is sent unless you send the email yourself, and you can delete this information before sending. Rating the app and updates go through the Google Play Store app, under Google's terms.
Ads, analytics, third parties
The app shows no ads, uses no analytics or advertising ID, and shares no data with any third party.
Deleting your data
You can delete all data by uninstalling the app or clearing its data in system settings, or with the "Delete all data" button in the app's Settings. Single sessions and attempts can be deleted in the app's journal. Android's backup copy can be deleted in your phone's backup settings or your Google account.
Children
The app collects no data, including from children.
Changes
If this policy changes, the new version will be published on this page with a new effective date.
