Your files never leave your device.

Plain-language summary of how this site handles your data. The short version: it doesn't.

  • We don't receive your files.

    Every viewer is JavaScript or WebAssembly running in your browser tab. There is no upload step. There is no server that could receive a file.

  • We don't store anything.

    Files live only in your tab's memory and are released when you close the tab. We do not persist filenames, contents, or thumbnails anywhere.

  • We don't track you.

    No analytics, no ad networks, no third-party scripts. The site loads fonts from Google Fonts via Next.js's font subsetting and that's it.

  • We don't require an account.

    There is nothing to sign up for. The site is free, open, and stateless from our side.

  • Network requests are limited to assets.

    The browser fetches the page, fonts, and (lazily) the WASM decoder a particular viewer needs. None of those requests include your file data.

If we ever change this — for example, if a future feature requires opt-in network access — we'll document the change here in plain English before it ships.
