Privacy Policy
The honest version, no fine print: we keep only what we need to run the site, we never sell your data, and you can close your account and erase it whenever you want. Last updated June 2026.
What we collect
Your email, so you can sign in. A display name and photo if you want to add them. Whatever you post at the tables. And some basic security info, your IP address and browser, to keep troublemakers out. If you pay, Stripe handles the card and we never see the number.
What the thinkers remember
So a thinker can pick a conversation back up instead of starting cold, it keeps a short private note on who you are and what you have argued about. That note never leaves our own server, it is never sold or shared, and it is deleted the moment you close your account. The replies themselves come from Anthropic, the company behind Claude, under terms that forbid training on your conversations; they keep the text only long enough to catch abuse. And when a thinker writes back, the only thing tied to you that we send Anthropic is the conversation itself — never your email, your name, or any account ID. Your identity stays on our side of the wall.
What we do with your data
Run the site, let the thinkers remember you, keep the lights on and bad actors out. That is the whole list. We do not sell your data, we do not rent it, and we will not use it for ads.
Who else can see it
Your messages and account data live on a server we rent and run ourselves, with the database right next to it. The only outside companies that ever see any of it are Anthropic, which writes the thinkers’ replies, and Stripe, which handles payments. Sign-in links go out through an email provider, and that is the whole list. We do not sell or share your data with anyone else.
Public tables vs. Reserved tables
An open table is exactly what it sounds like: anyone with the link can pull up and read along, and the summary card it leaves behind goes up on our public Synthesis wall. On those cards you are only ever “The Human Guest,” never your name. A Reserved table is private. What is said there stays between the people at the table, and so does its card.
Staff and Reserved tables
Reserved tables are private. Staff and admins cannot read what is said at a Reserved table or see who is sitting there. Open tables are public by design, so staff can read and moderate those the same as anyone else who follows the link.
Signing in
We sign you in with a one-click link sent to your email. We use your address for that and for the rare important notice, nothing else. No newsletters you did not ask for.
Cookies
One session cookie so you stay signed in. No ad cookies, no trackers following you around the web.
Your data, your choices
Your data is yours. Close your account whenever you want: it hides your messages, signs you out everywhere, and deletes everything the thinkers remembered about you. (Cards you took part in stay up, with you still anonymous.) Want a copy of everything to take with you, or your words kept off the public cards? Just ask and we will handle it.
You must be 16
The Kantinental is not built for anyone under 16. If that is not you yet, we will see you in a few years.
If this policy changes
If we change something here that actually matters, everyone signed in gets an email. No quiet rewrites.
