プライバシーポリシー

Last updated: October 2026

The one rule We collect as little as possible.

We built this service to need as little of your data as we can. Everything below spells out exactly what we collect, what we don't, and why.

What we collect, and what we don't

We count page visits with simple, privacy-friendly analytics, just to see which formats are popular. No personal profiles, no advertising trackers, no selling of data.
Your star ratings and small preferences are saved in your own browser (local storage), not on our server.
Standard server logs may record your IP address and browser for a short time, to keep the site running and to stop abuse. We don't use them to track you around the web.
If you use an "open from a link" option, we fetch that file for you so it can be opened. We don't keep it afterwards.

Cookies

We use only the cookies we need to run the site and remember your choices, such as your language. No advertising or cross-site tracking cookies.

Other people's tools

Some viewers load open-source libraries from a public code network (CDN) the first time you use them, so your browser can open that format. Those providers may see your IP address as part of serving the file, the same as any website you visit.

Your choices

We don't build a profile of you, so there is little for us to delete on your behalf. You can clear your browser's storage any time to wipe saved ratings and preferences. If you ever have a question about your data, just ask.

Changes

If we update this policy, we'll change the date at the top. We'll keep it as short and clear as we can.
