Privacy policy

Effective 10 October 2026. This policy covers the Daywitness app for iPhone and this website.

Summary

Daywitness is built so that its developer never receives your locations or your day records. The app has no sign-in, sends nothing to a server run by us, and includes no third-party code for analytics, ads or tracking. On the App Store it is labelled “Data Not Collected”.

Location

If you allow it, the app asks iOS for significant location changes and visits, and for a single reading when you open it or when iOS gives it a short background slot. It does not run continuous GPS. Each reading is stored in the app’s own storage on your iPhone and converted to a country, state or city with a map that is part of the app, so coordinates are never sent anywhere for that purpose. Readings that look like they were taken during a flight are kept but do not count as presence.

Location is optional. Every feature, including the paid ones, works with days you add by hand. You can change the permission at any time in iPhone Settings.

Day records and settings

Your stays, corrections, counters, people you track (for example family members, entered by you) and settings are saved in the app’s storage on your iPhone. A short summary for the home and lock screen widgets is written to an area shared only with the Daywitness widget.

Backups and exports

If you turn on iCloud backup, a copy of your records goes into your personal iCloud account, in the app’s iCloud container. It is subject to Apple’s iCloud terms and we cannot read it. Reports (PDF and CSV) and backup files are created on your iPhone and only leave it if you share them yourself, for example with your accountant.

Reminders and alerts

Evening reminders and limit alerts are set up by the iPhone itself, as iOS local notifications. No push service is involved.

Purchases

The yearly subscription is an App Store subscription, and Apple takes the payment; the app only asks the App Store whether you have an active subscription and until when, and keeps that date on your iPhone.

This website

daywitness.com is a set of static pages hosted on GitHub Pages. No cookies, no scripts. GitHub may keep standard server logs, such as IP addresses, under its own privacy statement.

Deleting your information

You can delete any stay or the whole record inside the app. Deleting the app removes its storage from your iPhone. An iCloud backup, if you made one, can be removed in iPhone Settings › your name › iCloud › Manage Storage.

Children

Daywitness is meant for adults keeping their own residency records. It does not knowingly receive information from anyone, children included.

Changes and contact

Any revision will appear on this page with its own effective date. Questions: support@daywitness.com.
