Sweatline is a personal training app for iPhone and Android. This policy explains what the app does with your information. The short version: it does not send anything anywhere.
Nothing. Sweatline has no account system, no analytics, no advertising, no crash reporting, and no backend server. The developer cannot see your data and receives no information about you or your device.
Everything you enter or generate in the app is stored in a local SQLite database inside the app’s private storage:
This data never leaves the device. The app requests no network permission in its release build, so it cannot transmit data even if it tried.
Two screens can hand something to your device’s share sheet: the workout summary as an image, and your backup as a file. Nothing is shared until you ask for it, and Sweatline plays no part in where it goes. The app you pick in the share sheet, including Photos if you choose “Save Image”, receives the file under its own privacy policy.
Settings contains an “Export” action that copies your data to the device clipboard as text, a “Share backup” action that hands the same data to the share sheet as a JSON file, and an “Import” action that reads the clipboard copy back. What you do with the exported data is entirely up to you. Sweatline does not upload it.
Your device’s operating system may include the app’s data in the backups it already makes (Google One backup on Android, iCloud or encrypted local backup on iOS). Those backups are handled by Google and Apple under their own privacy policies, not by Sweatline.
Sweatline keeps the screen awake while a workout is running and uses haptic feedback for the rest timer.
If you switch on the daily reminder, the app asks for permission to send notifications and reads your device’s time zone so the reminder fires at the hour you picked. The reminder is scheduled by the operating system on the device; no server is involved, and no reminder or time zone information leaves the phone. Turning the reminder off cancels it.
On iOS the app declares permission to add an image to your photo library, which the system requires because “Save Image” is one of the options in the share sheet. Sweatline never reads your photos.
Beyond that it requests no runtime permissions, no location, no camera, no contacts, no health data, and no internet access.
Sweatline is not directed at children under 13. It collects no data from anyone of any age.
Uninstalling the app removes its database and every trace of your data from the device. There is nothing else to delete, because nothing is stored anywhere else.
If this policy changes, the updated version will be published at this address and the “Last updated” date above will change.
