Summary
Wakwacht is a logbook you fill in yourself: ice-thickness measurements, frost readings, your thickness bands and your tour diary. There is no sign-in, no server, and no analytics or advertising. Everything you enter stays stored only on your own device, inside the app's private storage area, and is never sent anywhere by us.
What the app stores on your device
- Your waters and measurements — names, places, drill-hole thickness readings, ice type, hazard notes and your own free-text notes.
- Daily frost readings — the morning minimum and afternoon maximum temperatures you type in by hand.
- Your thickness bands — the activity thresholds you set or edit.
- Your toertocht diary — tours, distances, companions and koek-en-zopie stops you log.
- Photos you choose to attach — either taken with the camera or picked from your photo library, saved inside the app's own Documents folder.
- App preferences — appearance, haptics and reminder settings, stored with
UserDefaults.
None of this data leaves your device. There is no account, no cloud sync and no remote database.
Permissions the app requests
- Camera — to photograph a drill hole so the picture sits next to that measurement. Requested only when you choose to take a photo; you can decline and pick an existing photo instead.
- Photo library — to attach an existing picture of a drill hole or frozen water to a measurement. The picker runs in a system sheet that never gives the app access to your full library.
- Notifications — to remind you to take your morning or afternoon reading, only if you turn a reminder on inside the app.
Data we do not collect
Wakwacht does not collect, transmit or sell any personal data, usage analytics, advertising identifiers or location data. The app contains no third-party SDKs, no tracking code and no network requests of any kind.
Children's privacy
Wakwacht is a general-audience logbook and does not knowingly collect information from anyone, including children, because it does not collect information at all — everything is stored locally on the user's own device.
Deleting your data
Because every measurement, photo and setting lives only on your device, deleting the app removes all of it. Nothing is retained anywhere else.
