Privacy
Your research is private by default.
The research workflow is local-first. This page explains the limited services used by the site.
Research data
Unsigned research is stored in your browser. If you choose to sign in, the site can copy research to a private account for backup and multi-project access. Research is not made public by signing in.
Authentication and hosting
Optional account authentication and cloud storage are provided through Supabase. The website is hosted on Vercel. Those providers process the technical information needed to deliver their services under their own privacy terms.
Analytics
The site uses Vercel Analytics to understand aggregate usage and improve the product. It is not used to sell personal research data or build advertising profiles.
Your choices
You can use the local workflow without an account, export saved reports, remove browser data through your browser settings, or request account-data assistance at hello@21st.capital.
