Sanmai is a quiet Pomodoro timer designed for sensitive minds. We keep data collection minimal and transparent.
This Privacy Policy explains what we (the “Sanmai Team”) do—and do not do—with your data.
Quick Summary
- No account, no third-party tracking.
- On-device by default: your presets, sounds, and timer settings stay on your device.
- No microphone, no location, no contacts.
- Optional diagnostics/crash logs may be provided by Apple/Google if you opt in at the OS level.
- If you email us, we’ll use your email solely to reply and support you.
For details, read on.
