Cookie policy
Buto uses only what it needs to keep you signed in and remember one choice. There are no advertising, analytics or social media cookies, and no third-party cookies.
| Name | Type | Why | How long |
|---|---|---|---|
sb-…-auth-token (may be split into .0, .1) | Cookie, strictly necessary, first party | Keeps you signed in securely. Set by our sign-in provider, Supabase, only when you sign in. | Until you sign out, or the session expires |
Service worker (sw.js) | Browser feature, only if you turn on push | Receives and shows push notifications. It doesn’t track you or store pages. | Until you turn push off or clear site data |
bc-theme | Browser storage, strictly necessary (only if you pick a theme) | Remembers whether you chose light or dark mode. Not sent to us. | Until you pick “Match my device” or clear your browser data |
bc-viewer | Browser storage, strictly necessary (only on public portfolios) | A random ID so a project’s view count goes up once per visitor per day, not every reload. It isn’t linked to who you are and isn’t used for anything else. | Until you clear your browser data |
bc-cookie-notice | Browser storage, strictly necessary | Remembers that you’ve seen the cookie notice, so it doesn’t keep appearing. | Until you clear your browser data |
Do I need to consent?
Strictly necessary cookies don’t need consent under privacy laws, because the site can’t work without them. We still show a notice the first time you visit so you know what’s used. If we ever add optional cookies, such as analytics, we will ask first, and they will stay off unless you say yes.
Controlling cookies
You can block or delete cookies in your browser settings. If you block the sign-in cookie, you won’t be able to stay signed in.
Other things that aren’t cookies
Fonts are served from our own site. Voice rooms contact Google’s STUN servers to set up a connection, which shares your IP address but sets no cookies. Figma prototypes on portfolio pages load only when you press “Load prototype”; Figma may then set its own cookies, under its own policy.
