The short version

Saignée keeps very little on your device, and none of it is used for advertising or cross-site tracking. We use cookies only where they are strictly necessary to sign you in, our analytics are cookieless by design, and a small amount of local storage remembers UI preferences. Because there is no non-essential tracking cookie, this is an informational notice — there is nothing to opt in or out of.

Strictly-necessary cookies

When you sign in, our authentication provider (Supabase Auth) sets cookies that hold your login session so you stay signed in as you move between pages. These are essential for the app to function and are exempt from consent requirements. Clearing them, or signing out, removes them; you simply have to sign in again.

Analytics (cookieless)

We use Vercel Analytics and Vercel Speed Insights to understand aggregate traffic and page performance. Both are privacy-friendly by design: they do not set cookies, do not use persistent identifiers, and do not build a profile of you across sites. They help us see which pages are visited and how fast they load, in aggregate only.

Functional local storage

We use your browser’s local storage for small bits of UI state so the app behaves the way you left it — for example, remembering that you dismissed this cookie notice or a one-time tip. This data stays on your device, is not sent to us as a tracking signal, and you can clear it any time through your browser settings.

Managing what’s stored

You can clear cookies and local storage at any time from your browser’s privacy settings. Removing the strictly-necessary auth cookies will sign you out; everything else is non-essential and safe to clear. For more on how we handle personal data, see our Privacy Policy.

Changes to this policy

If we ever introduce a cookie or technology that isn’t strictly necessary, we will update this page and add a proper consent choice before using it.
