Cookie Policy
Last updated: 11 July 2026
LessonBrief uses only the cookies it needs to sign you in and keep the service secure. No advertising cookies, no tracking, no profiling.
What cookies are
Cookies are small files a website stores in your browser. Some are essential to make a site work at all; others are used to measure traffic or to advertise. This page explains which cookies we use and why.
The cookies we use
We only use cookies that are strictly necessary to run the service — the ones needed to deliver something you have asked for, such as signing in. They are:
- Sign-in / session cookies (set by our database and auth provider, Supabase): these keep you securely signed in as you move between pages. Without them you could not stay logged in.
- Bot-check cookie (set by Cloudflare Turnstile) — only on the sign-up page, and only when bot-protection is switched on: a short-lived security cookie that helps tell real people from automated abuse when an account is created.
What we do not use
We do not use advertising cookies, cross-site tracking cookies, or third-party analytics that profile you. Our error-diagnostics provider (Sentry) runs on the server only and does not set any cookie in your browser. We do not sell or share cookie data.
Why you do not see a cookie banner
Under the UK's Privacy and Electronic Communications Regulations (PECR), cookies that are strictly necessary to provide a service you have requested do not require a consent pop-up. Because we use only those, we do not interrupt you with a cookie banner. If we ever add non-essential cookies, we will ask for your consent first.
Managing cookies
You can view, block or delete cookies through your browser settings. Please note that blocking our essential cookies will stop you from signing in, so the service will not work.
Changes and contact
We may update this Cookie Policy as the service develops; the date above shows the latest version. Questions? Email us at lessonbrief@proton.me.
