FastWindow has no account, no server of its own and no ads. Your plan, fasts, start and end times, moods and notes are stored only on your phone.
Fasting times, moods and notes can be sensitive. They never leave your phone unless you export a backup or CSV file yourself. FastWindow is a timer, not medical advice.
FastWindow contains no analytics, no crash reporting service, no advertising SDK and no advertising ID. Nothing you enter leaves your phone unless you choose to export or share it. If this ever changes, this page will be updated before the change ships.
Backup files and CSV exports are created only when you ask, and go only where you choose to share or save them.
Start reminders, the running-fast notification and goal alerts are all scheduled locally on your phone.
FastWindow Pro is a one-time purchase processed by Google Play. We receive no payment details; Google Play tells the app only whether Pro was bought.
Use Settings → Back up or restore → Erase all fasts, or uninstall the app.
FastWindow is not directed to children under 13.
