Cookie Policy
Last updated: 29 September 2026
Proto Brand Builder uses only the cookies and browser storage it needs to work. We don't use analytics, advertising or tracking cookies. Because everything below is strictly necessary for the service you've asked for, UK law (the Privacy and Electronic Communications Regulations) doesn't require us to ask for consent, so you won't see a cookie banner.
Cookies
| Name | Purpose | How long |
|---|---|---|
pbb.auth | Keeps you logged in. Only set when you log in. | 14 days, renewed while you use the site (or until you log out) |
pbb.csrf | Security: stops other websites submitting forms on your behalf. | Until you close your browser |
.AspNetCore.Mvc.CookieTempDataProvider | Carries a one-off message (such as "Password changed") to the next page. | Until you close your browser |
Browser storage
| Name | Purpose | How long |
|---|---|---|
bk-post:… (local storage) | Saves the social post you're writing in the post composer, so it's still there if you come back. It stays on your device and isn't sent to us. | Until you choose "Start over" or clear your browser data |
Third parties
Our pages load typefaces from Google Fonts, which means your browser connects to Google's servers. We don't allow Google Fonts to set cookies for us. See our Privacy Policy for what Google receives.
Websites you make with Proto Brand Builder
Websites exported from the builder set no cookies. If you add your own tools to them (analytics, for example), you're responsible for your own cookie notice.
