Cookieless analytics
We measure traffic with Umami, which uses no cookies or local storage and stores no data that could identify a visitor. The data is aggregate only (number of visits, country, device type).
Browser local storage
The photo-tag editor may save your work in progress (photos and settings) to your browser’s local storage (IndexedDB / localStorage) so that you don’t lose it when the page reloads. We also store in localStorage that you dismissed the cookie information bar (so it doesn’t keep reappearing). This data stays solely on your device, is not transferred to the server, and you can delete it by clearing your browser data or directly in the app.
