Ken lives on your computer. What you tell it, what it remembers and what it does for you stay there.

What stays on your computer

• Your conversations, Ken's memory and everything in its Brain
• Your files, keys and logins
• Your email, calendar and anything else you connect

Ken itself runs on your own Claude or ChatGPT account: when it thinks, your messages go to Anthropic or OpenAI under your plan, the same as using Claude or ChatGPT directly. If you use Ken on your phone, those messages travel through Telegram.

What Ken shares with us

To find and fix bugs, and to see which features people actually use, Ken sends two kinds of anonymous reports to our analytics provider, PostHog. You can turn both off at any time (below).

Crash reports, when something goes wrong:

• the kind of error, its message and where in Ken's code it happened
• Ken's version, your operating system and the Python version

Before anything leaves your computer, Ken replaces your home folder with ~ and hides anything that looks like a key, token or password. An error message can still occasionally include a little of what Ken was working on when it failed, such as a file name.

Usage counts: that something happened, never its content. For example: Ken started, a message was answered (and whether it came from the app or your phone), a voice note was transcribed (and how long it was), a scheduled job ran, a setup step was done or skipped, the model was changed.

Reports are tied to a random ID made on your computer, not to your name, email or account. They never include your messages, Ken's replies, your memory, your files, or your keys.

Turning it off

In the Ken app: Settings → Privacy, switch off Share anonymous crash reports and usage. Ken stops sending straight away and remembers your choice.

Running Ken from the terminal? Add KEN_CRASH_REPORTS=0 and KEN_USAGE_STATS=0 to ~/.ken/.env.

Ken on your phone

When you connect Telegram by scanning the QR code, your phone encrypts your bot's code before sending it to Ken through kencomputer.dev. Only your computer holds the key: our server only ever sees scrambled data, keeps it for at most 10 minutes, and deletes it once your computer picks it up.
