Plainly.

What we keep about you

When you sign in with Google: your Google account’s id, your email address and your name — to know it’s you, and to put your name on the “you” at the centre of your map. Kith never sees your Google password. A cookie on this site keeps you signed in to your map, and that is its only job. No third-party analytics, no tracking, no ads.

Kith also counts, each day, how many times your assistant used each of its tools (looking someone up, saving a note) — only the numbers, never what was asked or said — so whoever runs Kith can see how it’s used and whether it’s working. Those counts are in your download, and go when you delete your Kith.

What you tell Kith

The people in your life, what you’ve told Kith about them, and who knows whom. It is yours alone: nobody else who uses Kith can see it, and the database itself keeps each person’s Kith apart from everyone else’s. Kith never sells it, never shares it, never shows ads against it, and never trains a model on it.

It reaches Kith through the AI assistant you connect it to: you talk to your assistant, and it hands Kith what you said. What happens to those conversations is governed by your own account with that assistant and its privacy settings, not by Kith — so check those settings if that matters to you.

Who else could see it

Kith is built and run by one person, on one server. Like most online services that aren’t end-to-end encrypted, whoever runs the server could technically read what is stored on it. Nothing in Kith shows your people to anyone else, and what you tell Kith is used for nothing but running it.

How much

Kith is free while it’s early. Each Kith holds up to 100 people, and up to about a megabyte of notes on any one of them — far more than a life’s worth of small details.

For how long, and leaving

For as long as you keep your Kith. On your map, your own brief has “Download everything”, which gives you all of it as a file, and “Delete my Kith”, which removes everyone and every note at once and signs you out everywhere. The server keeps nightly backups for fourteen days, so a deleted Kith is gone from those within two weeks.

If you search your own name

The “do you know each other?” page answers only for people the owner has chosen, one by one, to be findable — and only people they have met, never family, never children. For them it says one of three things (you’re friends, you work together, or they know you) and one line the owner picked or wrote — never their notes, and never anyone else’s name. Being findable ends by itself after 180 days.

Names are shared, so the page never assumes it has found you, and it has nothing to take back: if you’d rather not be there, ask the owner. For everyone else, including people not in Kith at all, the answer is the same “nothing here”, so a search can’t tell who is in Kith. It matches whole names only, and a handful of tries a minute. Searches aren’t stored.

This site

Everything on this page, fonts included, is served from here. Loading it tells no one else that you visited. Your light or dark choice is saved in your own browser and never sent anywhere. The “Book 20 minutes” link is the one exception to staying here: it opens Google Calendar’s booking page, and what you enter there is handled by Google.
