Privacy
What trackline collects, what it never collects, and how to delete it. Last updated 24 September 2026.
The short version
- The trackline command-line tool runs on your machine and sends nothing anywhere unless you connect it to an account.
- This website sets no tracking cookies and runs no analytics.
- If you connect an account, trackline sends what it noticed about your agent's actions. Never your code, never your file contents, never the text of your commands.
Using trackline without an account
Everything stays on your computer, in a .trackline folder inside each project. Nothing is sent to us or to anyone else. If you turn on the optional judge, trackline sends your request and a one-line description of each action to the model provider you chose; that goes directly from your machine to them, not through us.
If you create an account
Accounts are optional and add a live dashboard. When you sign in we receive, from GitHub or Google:
- your name, email address and profile picture;
- an identifier for your GitHub or Google account, so you can sign in again.
We never receive your GitHub or Google password, and we do not ask for access to your repositories.
What a connected machine sends
Only after you run trackline connect, and only for projects you choose:
| Sent | Never sent |
|---|---|
| the project's folder name, and a random id for it | file contents, diffs or patches |
| which agent, and a session id | the text of shell commands |
| the kind of each action: edit, write, delete, read, command, tool call | tool arguments |
| file paths, relative to the project | anything outside the project |
| names of packages installed | environment variables |
| what each check concluded, and why | |
| what you asked your agent, if you agree when connecting |
File paths can say more than they seem to. A name like clients/acme/merger.md is sent as written. Do not connect projects whose file names you would not want stored.
What you ask your agent is sent only if you say yes when connecting, and you can turn it off at any time with trackline connect --no-requests.
Production traces
If you connect trackline serve, it sends results only: tool names, their outcomes, findings, counts and timings. It never sends the traces themselves, your customers' messages, model replies, tool arguments or system prompts, unless your team explicitly turns that on.
Where it is kept, and for how long
- Account data and events are stored on servers in the United States.
- Events are kept for 30 days on the free plan, then deleted.
- The website is hosted by Vercel. Sign-in is provided by GitHub and Google under their own privacy policies.
- We do not sell your data, share it with advertisers, or use it to train models.
Deleting it
Deleting your account from the account page deletes your account and every event we hold for it. You can disconnect a machine at any time, from the dashboard or with trackline disconnect, and it stops sending immediately.
