flüf runs entirely in your browser — no download, no app store, no updates to manage. You can use it on your phone, tablet, or computer from any browser you already have.
We built flüf as a web app deliberately. It means you can get to your pet's record instantly, from anywhere, without friction. It also meant we could build something well-crafted and thoughtfully designed without the cost of maintaining separate iOS and Android apps at the same time. flüf is self-funded, and building web-first let us put every pound into the product itself.
That said, being a web app does not mean cutting corners on security. Your data is stored securely, access is protected, and we take your privacy seriously. We do not sell your data, and we never will.
To sign in, flüf uses a magic link — a secure, one-time link sent to your email address. No password to create, forget, or lose. Just click the link and you're in. It's one of the safest ways to authenticate, and it keeps things simple.
