Privacy policy

Effective October 14, 2026, updated October 20, 2026. Applies to the Asof app for Android and iPhone and to the website www.asof.day.

Asof is a camera that puts the date, time and place on your photos and turns them into reports. It has no account, no ads and no analytics. Your photos stay on your phone. This page lists everything the app keeps and the few things that leave the phone.

What stays on your phone

• Photos and reports. A copy of each photo you take with Asof or add from your gallery, the stamped copies, your report details (title, job, notes, addresses), signatures you collect, and your logo. They are stored in the app's private storage. We never receive them. They are deleted when you delete a report or uninstall the app.
• Your gallery. If "Save camera photos to the gallery" is on (or you save a photo yourself), a stamped copy goes to the album "Asof" on your phone. Deleting it there does not affect your reports.
• Files you share. PDFs, CSV, ZIP and map files are created on your phone and go only where you send them.
• Location inside stamped photos. When the stamp shows the address or coordinates, the stamped photo file also keeps the GPS position where it was taken, so gallery apps can show it on a map. Anyone you send a stamped photo to can read that position. To leave it out, turn off address and coordinates in Settings › Setup.

What leaves your phone, and why

• Address lookup. When the camera is open and you allowed location, or when a photo you add from your gallery has a GPS position in its file, that position is sent to your phone's address lookup service (Google on most Android phones, Apple on iPhone) to find the street address. Asof does not send it anywhere else. Location is optional; without it photos still get date and time.
• Clock check. While the camera or Settings is open, Asof makes one ordinary web request to asof.day (or to google.com if asof.day does not answer) and reads the server's time to compare it with your phone's clock. The request contains nothing about you or your photos. Like any web request, it reveals your IP address to that server. The asof.day server is run by Cloudflare.
• Purchase. The one-time unlock is sold through Google Play on Android and through the App Store on iPhone. Google or Apple handles the payment; we never see your card details. The app asks the store whether your store account owns the unlock, so it can be restored on a new phone.
• Backup. Android may back up your Asof settings (company name and options) to your Google account; iPhone may include the settings and your logo in an iCloud or computer backup. Photos, reports and signatures are excluded from both backups.

What we do not do

• No account and no sign-in.
• No advertising, no advertising identifiers, no analytics or usage statistics.
• No sale or sharing of personal data.

Google Play and the App Store may give us anonymous crash and performance statistics about the app, as they do for every app in their stores.

Permissions

• Camera — to take photos.
• Location (while the camera is open) — for coordinates and the street address on photos. Optional.
• Internet — for the address lookup, the clock check and Google Play.
• Photo location (Android 10 and newer) — to read the GPS position saved in photos you add from your gallery. Optional; without it those photos get no location.
• Storage (Android 8–9 only) — to save stamped photos to the gallery. Newer Android versions need no permission for this.

Photos from your gallery come through Android's file picker, which gives Asof only the photos you choose.

iPhone

• Camera — to take photos.
• Location (while using the app) — for coordinates and the street address on photos. Optional.
• Photos, add only — to save stamped photos to your Photos library when you ask for it. Asof does not ask to read your library; photos you add come through the system photo picker, which gives Asof only the photos you choose.
• Network — for the address lookup, the clock check and the App Store.

Children

Asof is a work tool and is not directed at children under 13.
