Privacy Policy

Last updated: June 2026

BuffSheets provides an Excel add-in that edits your workbooks using AI. This policy explains what data we handle and your choices.

Hosted vs on-device

On-device models keep workbook data on your computer. Hosted models send selected workbook context to the BuffSheets gateway and your chosen AI provider.

Account & billing

We use Clerk for authentication and Stripe for payments. We do not store full credit card numbers. You can manage billing and subscriptions at your account page.

Your choices

Opt out of training-data logging anytime in account settings.
