This service is operated by Vysa Trading LLC. You can reach us at support@vysatrading.com.

1. The service

Vellum detects and redacts personal data in PDF documents you voluntarily upload. You are responsible for having the right to process the documents you use in the tool.

2. Plans and credits

One credit equals one page processed. Completely blank pages don't use a credit. Unused credits from one cycle do not roll over to the next unless stated otherwise.

3. Detection accuracy

Detection is performed by an AI model and can make mistakes — both flagging too much and missing something. That's why the tool requires you to review every detection before downloading, and lets you cover areas by hand. Final responsibility for the downloaded document is yours.

4. Payments

Payments are real and processed through Polar (Polar Software, Inc.), the authorized reseller of our plans. You can cancel anytime from your Polar customer portal; cancellation takes effect at the end of the period you've already paid for.

5. Acceptable use

You may not use the service to process illegal content, or attempt to overload or bypass the system's usage limits.

6. Cancellation

You can cancel your plan at any time from Account & plan; you'll immediately return to the free plan.
