Your letter is yours.

Plain-language summary of what happens to what you upload. Last updated October 30, 2026.

What we don't do

  • We don't store your letter, your results, or your reply.
  • We don't require an account.
  • We don't sell or share data, and we don't use letters to train models.
  • We don't use advertising or tracking cookies.

What happens when you check a letter

  • Reading: the letter text (or photo) is sent to NVIDIA Nemotron models on Nebius Token Factory to be read and checked, then the result is returned to your browser.
  • Search: short queries (such as your state and the type of notice, never the letter itself) are sent to Tavily to find regulation text and local help.
  • Regulations: regulation text is fetched from the official eCFR.

Hiding names

Before checking, you can list names to hide. They are replaced with “[REDACTED]” in your browser, before anything leaves your device.

Downloads stay with you

Calendar files, reply letters, and evidence packets are generated in your browser and saved to your device only.

Self-hosting

Organizations can run Holdline on their own infrastructure with their own Nebius key. See the source code.
