This page explains the cookies and similar technologies QRLumen uses.
Essential
If you sign in, our authentication provider (Clerk) sets a session cookie so you stay logged in. The site can't function as an account service without it.
Analytics
We use Google Analytics via Google Tag Manager, which sets cookies (e.g. _ga) to measure aggregate, non-identifying usage. We also use Cloudflare Web Analytics, which is cookieless.
Payments
If you start a checkout, Stripe may set cookies needed to process the payment and prevent fraud.
Controlling cookies
You can decline analytics cookies via the notice shown on the site, and you can clear or block cookies in your browser settings at any time. Blocking essential cookies may break sign-in.
