Cookies
A complete list. Public visits set zero cookies. The only cookies on this site appear when an admin signs in, and they are strictly necessary for that function.
What you'll see as a visitor
If you're just here to read about the book, sign up for the waitlist, or click around — no cookies are set on your browser. We don't run analytics, advertising, or social-media trackers. The waitlist form posts directly to our server, which forwards your email to our email service provider; no third-party scripts are loaded.
For that reason, you don't see a consent banner. There is nothing to consent to.
Cookies set when an admin signs in
If you sign in to the admin area at /api/auth/login with a Google Workspace account on the whichidea.com domain, the following cookies are set on this site. Both are strictly necessary for the admin function and require no consent under the GDPR / ePrivacy Directive.
| Name | Purpose | Type | Lifetime |
|---|---|---|---|
admin_session |
Signed session cookie that authenticates an admin across page loads. Contains the admin's email and Google user ID, signed with a server-side secret. HTTP-only, Secure, SameSite=Lax. | First-party, strictly necessary | Up to 7 days, or until sign-out |
admin_hint |
Non-sensitive flag used by the public page to decide whether to load the admin overlay JavaScript. Contains no personal data — only a value indicating that an admin session exists. Without this flag, the admin bundle is never fetched, so public visitors pay zero extra bytes. | First-party, strictly necessary | Up to 7 days, or until sign-out |
Both cookies are removed when you click Sign out in the admin bar, or when they expire.
Third-party cookies
None on whichidea.com itself. The Google sign-in flow temporarily redirects you to accounts.google.com, which is a different site under Google's own privacy and cookie policies — once you're back on whichidea.com, no Google cookies are set on our domain.
Changing your mind
To remove the admin cookies, sign out from the admin bar. To remove all whichidea.com cookies, clear them via your browser's site-data settings.
If we ever add analytics
This page lists every cookie on the site. If we ever add analytics or any other non-essential cookie, we will (a) update this page, (b) add a real consent banner to the homepage, and (c) only set those cookies after you've explicitly opted in. We are not planning to do this any time soon.
