Privacy Policy

Last updated: October 2, 2026

OpenSI (opensidot.com) is a directory of SI models. It has no accounts and no cookies, and the comparison tools and cost calculator run entirely in your browser — nothing you type into them is sent to us.

Analytics

We count visits with Umami, an open-source analytics tool we host ourselves and load through this site. It records the page viewed, the referrer, browser, operating system, device type, language and an approximate location derived from your IP address. Umami sets no cookies and does not keep your IP address in readable form. We never use it for advertising.

Hosting

The site runs on Cloudflare, which processes your IP address and request details to deliver pages and protect against attacks, and may keep short-term logs for that purpose.
