Privacy Policy
Effective April 29, 2026
Parallelogram is built on the principle that your training data should never leave your machine. This policy describes the very small amount of information involved in using our website and our software.
The CLI: zero collection
The parallelogram command-line tool collects nothing. It runs entirely on your local
machine. It does not phone home, does not send telemetry, does not upload your dataset, does not
check for updates, and does not communicate with any server we operate. The only network call the
tool ever makes is the optional, user-initiated download of a tokenizer from Hugging Face when you
pass --tokenizer; that request goes directly to Hugging Face under their privacy policy,
not to us.
The website: minimal collection
This website (parallelogram.dev) is a static page hosted on Vercel. We do not run analytics, tracking pixels, advertising scripts, or behavioral fingerprinting. The fonts loaded from Google Fonts may transmit your IP address to Google as part of the standard HTTP request — this is the only third-party request the page makes.
Vercel, our hosting provider, automatically logs basic request metadata (IP address, user agent, URL requested, response status) for operational and security purposes. We do not access these logs for analytics. Vercel's data practices are described in their own privacy policy.
Email correspondence
If you email us, we will see your email address and the contents of your message. We use these only to reply to you. We do not add you to a mailing list, share your address with third parties, or use your message for any other purpose.
Cookies
This website does not set any cookies.
Children's data
Parallelogram is a developer tool not directed at children, and we do not knowingly collect data from anyone.
Changes to this policy
If this policy changes — for example, if a future paid product introduces a backend that does process data — the new policy will be posted here with a new effective date, and the substantive change will be prominently disclosed. Your continued use after a change constitutes acceptance.
