Privacy policy

This site (media.tools.ryusei.io) is a free, individually run collection of in-browser media conversion tools. This page describes how users' files and data are handled.

Files you process

Conversion, compression and editing of images, audio and video all run inside your browser. Files and their contents are never transmitted to this site's servers, and this site never stores or views them.

Analytics

Google Analytics is used to improve the site. Statistics such as pages viewed, time on page and browser type are sent to Google; the contents and names of processed files are not included.

Advertising

Ads are served through Google AdSense to cover running costs. Google may use cookies to show ads based on your interests. Personalised ads can be disabled in Google's Ads Settings.

Cookies

Cookies are used for the theme setting (light / dark) and for the analytics and advertising described above. No information about processed files is stored in cookies.

Processing statistics

To improve the service, this site collects statistics about whether processing succeeded on its own server. What is sent: the tool you used and the settings you chose (output format, quality, etc.), your device specs (GPU, memory, core count), the input format with a rough size, how many files succeeded or failed and how long it took, and the error type and details when something fails. The files themselves, file names, text, subtitles or prompts added to a video, and IP addresses are not sent. The data is deleted automatically after 30 days and is never shared with third-party services. You can turn it off at any time with the switch at the bottom of each tool page, and nothing is sent if your browser signals Do Not Track or Global Privacy Control.
