Console privacy

This console stores only what it needs to let you manage your site keys:

From your identity provider: your account id, and the name and email address it shares, held in your session while you're signed in.
A session cookie (strictly necessary, HttpOnly) that expires after inactivity. No analytics or advertising cookies.
Your sites: names, domains, settings and daily totals, linked to your account id. Secrets are stored only as hashes.

What the CAPTCHA itself does to your visitors is described on the Obol privacy page.
