What we store

Reading needs no account, and nothing you read is tied to you. This is everything we keep about the people who do have accounts, and how to get rid of it.

Your account — email and sessions

An email address, the sign-in sessions it opens, and the times it signed in. That is the whole account. There is no password to leak, because there is none: signing in is a one-time link to your email.

What you publish — public by intent

A published Practice is public on purpose: it is a document at a permanent address, sealed with a content hash, versioned, and credited to whoever it credits. You can withdraw a version, and its URL then answers 410 rather than pretending it never existed. Attribution is permanent — a Practice someone else adapted still names you as its source. The handle terms govern withdrawal, reclamation and impersonation.

Proofs — only what you linked

If you link an external account as a proof, we store the account's URL, the method, and the date it was verified. Nothing else travels from that account — no followers, no email, no activity. Unlinking deletes the record and every display of it.

Analytics — cookieless, aggregate

We count page views in aggregate. No cookies, no fingerprinting, no cross-site tracking, no profile of you, and no way for us — or for a Practice's author — to see who read what.

Who else touches it — three processors

  • Vercel — hosting and delivery.
  • Neon — the database.
  • Resend — sending your sign-in email.

Nobody else. Your data is not sold, rented, or handed to advertisers, and it is never used to train a model.

Your controls — all self-serve

  • Export — your whole account as one JSON file, content hashes intact, from your account page.
  • Delete — the account goes, published versions stop being served, and your handle becomes a tombstone that is never reassigned. Copies other people already made stay theirs.
  • Unlink — remove a proof and every display of it.
  • Withdraw — take a published version out of circulation without deleting your account.

Asking — a person answers

Questions, corrections, or a request this page does not cover: privacy@ctrlai.com. To report a handle or a Practice, use the report form — no account needed.
