Cookies Policy

Postr sets no cookies. It keeps items in your browser's storage, such as your sign-in session, the presets, palettes, notes and profile details you save, a marker that warns you when the same poster is open in two tabs, and short-lived values for the current tab.

Page views are counted with Vercel Web Analytics only, which as Postr uses it sets no cookie and writes nothing to your browser, and which Postr does not load when your browser sends Global Privacy Control. Poster ids and query strings are removed from the page address Postr reports. Postr runs no advertising and no cross-site tracking.

Some features load files from other services: the editor's fonts from Google Fonts, which receives your IP address and user agent each time, and preset university logos from Google and Wikimedia sites. Payments and billing open on Stripe's own pages.

Deleting this storage signs you out, and a guest without an account can then no longer open their posters. If you block storage for postr.sh, Postr cannot keep you signed in from one page load to the next, and the editor may not work. The full policy lists each entry, where it is stored, what it does and how long it lasts, and how to clear it in your browser.
