About Clyvora

Useful tools with a clear privacy boundary.

Clyvora—also known as Clyvora Tech or Clyvora Technologies—is an independent software project creating focused, source-available browser tools for data and media.

What Clyvora builds

Clyvora builds tools for data, media, and live train locations. Lens and mewvi process selected local files in your browser without uploading them. Public-link downloads in mewvi use Clyvora infrastructure and contact the source platform; Live op Weg uses online railway data.

Clyvora uses Vercel Web Analytics for anonymous, cookie-free traffic statistics. Standard page views may include the visited path, referrer, coarse location, browser, operating system, and device type. Clyvora does not configure custom analytics events, and filenames and file contents are never included.

The projects are published as source-available software so people can inspect how the tools work, report problems, and contribute improvements under their respective license terms.
