Saunailta
Last updated November 11, 2026
Saunailta is a sauna-evening log for Finnish families and mökki owners. It was built to run entirely on your own device, and this page explains exactly what that means.
Saunailta does not collect any personal data. There is no account, no backend server, no analytics and no advertising. Everything you enter — bathers, Saturday pages, rounds, water, lake temperatures, notes and any photo you attach — is written to a file inside the app's own storage on your device and never leaves it.
Saunailta keeps a single data file in its private Documents folder, created and managed by Apple's standard file system APIs. It holds:
None of this is transmitted anywhere. There is no server for Saunailta to send it to. If you delete the app, this data is deleted with it.
If you choose to photograph a sauna evening, Saunailta asks for camera access at that moment and explains why. The photo is copied into the app's own storage; it is never uploaded. You can also add a picture from your photo library using Apple's system picker, which does not require any permission grant to Saunailta and does not give the app access to your library beyond the single photo you pick.
Saunailta can remind you, with a local notification, when the stones are likely ready or when a Saturday evening usually begins. These notifications are scheduled entirely on your device using Apple's notification framework. No notification content or token is sent to us or to any third party, because no server is involved.
Saunailta contains no tracking SDKs, no advertising network, no analytics library and no third-party service of any kind. It does not link your activity to your identity, your device, or any other app, because it never leaves your device in the first place.
Saunailta collects no data from anyone, including children, for the same reason: everything stays on the device that installs it.
Saunailta is a planning and logging tool for a traditional sauna evening, not a medical or health product. It makes no health claims, offers no diagnosis and does not measure heart rate or other body data. A plain reminder appears in the app that sauna and alcohol don't mix, and that anyone feeling unwell should step out and rest.
If this policy ever changes — for example if a future version of Saunailta adds a feature that does collect data — this page will be updated first, and the in-app copy of this policy will be updated alongside it.
