Why browser-only?
Most online utility sites send your data to a server to do the work. That's fine for the operator, but it means a third party briefly holds whatever you typed or dropped in. Toolcroft skips that pattern entirely. Each tool is a small JavaScript program that runs on your machine. There is no backend handling your tool data.
Every release is checked by an automated test that fails the build if a tool makes an unexpected network request. The privacy promise is enforced at the build step, not just written on a page.
