Stample is a mobile app that allows you to collect virtual stamps--- not the kind you stick onto a letter, but the kind you get in your passport when you travel.
We have hidden our stamps on lots of cool real-world locations* for you to discover. If Stample is installed on your mobile device, all you need to do is be at such a location, and you'll be notified automatically. Then, collecting the stamp is as simple as tapping the screen!

Build your own collection of digital souvenirs, or trade stamps with friends to help each other. It's easy, fun, and 100% free!
Travel. Stamp. Collect. Can you find them all?
* Stample is currently kicking off in the Netherlands. Download the app in the Dutch Google Play Store.

Privacy
Stample is a location-based mobile app, but it stores and shares very little information about its users. Long story short: we obviously keep track of the stamps you've collected, but everything else is up to you. Our privacy policy explains all the details.
