Trace draws each route on the map. The line shows how you moved. Each evening, Trace writes a short story of your day.

You can add notes and photos. You can also correct a stop that is not correct.

Your journal stays on your iPhone.

You should not have to trust a company with your location history. With Trace, you do not have to. We do not receive your journal, so we cannot read it, sell it or lose it in a data breach.

  • Encrypted on your iPhone

    Trace encrypts your journal on your device. We do not operate servers that receive your journal. We cannot read it.

  • You control the recording

    Trace records nothing until you tap Start recording. You can pause it from the app, the widget, the Lock Screen or Siri.

  • No account and no ads

    You do not sign in. We do not sell your data or track you across other apps. iCloud sync and analytics are off by default.

Questions

Can you see where I go?

No. We do not operate servers that receive your journal. Your journal stays on your iPhone, or in your own iCloud account if you turn on iCloud sync. Trace encrypts it before it leaves your iPhone. Optional analytics never include your locations, routes, places, notes or photos.

Does Trace use much battery?

No. Trace uses the low-power location service of iOS. With the Always permission, Trace uses this service to fill in your full day.

Does Trace record all the time?

No. Trace records nothing until you tap Start recording. With the While Using permission, Trace records only when the app is open. You can pause Trace at any time, also from the Lock Screen.

Do I need an account?

No. You do not need an account, and you do not sign in.

Can I erase all my data?

Yes. In Settings, tap Erase Journal. This erases every day, place, route, memory and saved place.

More answers are on the support page.

Start your first day.
