Event preparation: once a day, Braindetangler automatically sends the details of your Google Calendar events for the coming seven days (title, start time, place and description) to Anthropic, our AI provider, to suggest tasks to prepare for them. No person reviews this step. To stop it, turn off “Suggest prep for calendar events” in Settings › Google Calendar, or disconnect Google Calendar.

Cookies

[Placeholder: cookies. The public site, including this page, runs no Clerk code and sets no Clerk cookie. Clerk runs when you sign in or use the app. Finding of the signed-out check on 2026-10-06, when the public site still ran Clerk: a browser request for /sign-in, on Preview (braindetangler-web-preview.vercel.app) and on production (braindetangler.com), is answered with a redirect to Clerk's development instance (picked-vulture-55.clerk.accounts.dev) and a single Set-Cookie, __clerk_redirect_count (HttpOnly, SameSite=Lax, 2 seconds). The cookies Clerk sets after that handshake were not observed and are still to be checked in the browser's developer tools. The site's analytics set no cookie. There is no consent banner in this release.]
