Privacy policy

Last updated 16 October 2026. Stamped is a small independent app made in the UK. Questions: hello@stampedapp.co.uk.

The short version. You can use Stamped without an account and we collect nothing about you. If you do create one, we keep what is needed to save your passport. We do not sell your data, show ads, or track you across other apps or websites.

What stays on your phone

Your progress: the stories you have read, check-ins, badges, stamps, and the things you have spotted. It is saved on your device.
Your location: used only while the app is open, to show landmarks near you and to check you in when you are at one. It is worked out on your phone. We do not receive it, store it, or keep a history of it.

What goes to other services

Maps. Map pictures come from Google Maps (or OpenStreetMap if Google is unavailable). Like any map, the provider sees which area you are looking at and your internet address. See Google's privacy policy.
Tickets. Some landmarks have a "Buy tickets" button that opens Tiqets in your browser. If you buy, we may earn a small commission, at no extra cost to you. Tiqets handles the purchase under its own privacy policy and we do not see it.
Fonts are hosted by us, so no other company learns that you visited. If Google Maps cannot load, the backup map loads its picture tiles from OpenStreetMap.

Friend stamps

Each install makes a random 8-character code. If you invite a friend and they open Stamped through your link, we store their code, your code, a scrambled form of their network address (to stop fake sign-ups), and the time. We store no names, emails or locations for this. These records are deleted automatically after 12 months.

Accounts (optional)

You can use Stamped without an account. After your first badge we offer to save your passport with Sign in with Apple or Google.

What we keep if you sign in: the identifier Apple or Google gives us for you, your email address and name if you choose to share them (Apple can hide your real email), a sign-in session on each phone (it expires after 180 days), and your saved passport. Check-ins record that you checked in, not where you were.
Why: so your passport follows you to any phone and survives losing one.
Deleting it: choose "Delete my account" in your Passport. Your account, sessions and saved passport are removed from our server straight away. The badges on your phone stay until you reset the app.
Who sees it: only us. Sign-in is checked with Apple or Google, which have their own privacy policies.
Sign-in attempts: to block abuse we keep a scrambled form of your network address for up to a day.

Anonymous usage counts

Stamped counts how the app is used, for example how many stories are read, which landmarks get badges, and how many people tap a ticket link. Each count is just an event name, a landmark name where relevant, the platform (web, iPhone or Android) and the day. We keep daily totals only. We do not record who you are, your device, your location or your internet address, and the counts cannot be linked back to you. We use Google Maps and Tiqets only as described above, and we do not use advertising or tracking services. You can switch the counts off in Settings.

Support messages

If you send a message through Contact support, we keep the message, your email if you add one, and the device details if you tick the box. We use them only to reply and fix problems, and delete them after 12 months.

Children

Without an account, Stamped collects no personal information, so people of any age can use it. Accounts are for people aged 13 and over, or the minimum age in your country if higher. We do not knowingly create accounts for younger children. If you think we have, email us and we will delete it.

Your rights

Under UK and EU data protection law you can ask to see, correct or delete the information we hold about you. Deleting your account in the app does the last of these immediately. For anything else, email hello@stampedapp.co.uk. You can also complain to the Information Commissioner's Office at ico.org.uk.

Changing your mind about location

You can turn location off in your phone settings at any time. Stamped still works, without the "near me" features.

Changes

If Stamped changes what it does with information, we will update this page and the date above.
