One for macOS · Last updated September 14, 2026
One does not collect any data. Not anonymized data, not usage statistics, not crash reports — nothing.
Nothing. One contains no analytics, no tracking, no advertising identifiers, and no user accounts. The app makes no network requests of its own.
Your timer durations, saved presets, preferences, and completed-session count are stored locally on your Mac using standard macOS storage. This information never leaves your device and is never transmitted to us or to anyone else. Deleting the app removes it.
The one-time unlock is processed entirely by Apple through the App Store. We never see, receive, or store your payment details, Apple Account, or any other purchase information. Apple's own privacy policy governs that transaction.
One includes no third-party SDKs, frameworks, or services. No data is shared with anyone, because no data is collected in the first place.
One collects no personal information from anyone, including children under 13.
If this policy ever changes, the revised version will be posted on this page with a new date above.
