Your data never leaves your device

Everything in your own browser

Converting, deduplicating, comparing, counting, sorting and making QR codes, barcodes and passwords: it all happens in your browser, on this device. Whatever you paste or open doesn’t go to a server of ours or anyone else’s. Handig Data doesn’t even have a server that could receive it: the site technically allows no outgoing connections.

What Handig Data does fetch

Handig Data only loads the parts of a tool when you open that tool, always from its own address, such as the part that reads and writes Excel files. That’s fetching, never sending.

Passwords

A password or passphrase that Handig Data makes, and a Wi-Fi password you put in a QR code, only exist in your browser while the page is open. Handig Data doesn’t keep them.

What your browser remembers

Only your preferences: light or dark, your language and your Reading aids settings. No text and no files. Also your last five searches, so you find them again in the search window; one button clears them.

What you send on yourself

Whatever Handig Data makes is an ordinary file in your downloads or text on your clipboard. If you send it on, it goes through your email or your storage, and their rules apply.

Technical logs

Like every web server, our hosting provider keeps short technical logs (such as IP address and time of a page visit) to keep the site running safely. They contain no text or files. We don’t use those logs to track visitors.
