How ToolkitHere works

Your files never leave your device. When you add a file, your own browser reads it and does the work. ToolkitHere's servers only send you the web page and the tool's code. They never receive your file, its name or anything inside it.

What happens when you add a file

1. You drop a file or choose one. The browser gives the page access to that one file, on your device.
2. The tool starts a Web Worker, a background helper that runs inside your browser tab.
3. The worker reads the file and turns it into a preview: a table of contacts, a list of events, or chat bubbles.
4. When you download a result, the worker builds the new file and your browser saves it. No server is involved.
5. When you close the tab, everything is gone. We keep no copy, because we never had one.

The safeguards

• The workers can't use the internet. The background helpers that read your files run under a browser security rule (a Content Security Policy) that blocks every network request from them.
• No accounts. There is nothing to sign up for, so there is nothing to link your files to.
• No file details in analytics or logs. We never record file names, sizes, contents or results.

Check it yourself

You don't have to take our word for it.

The airplane-mode test

1. Open a tool and add one file, so the tool has finished loading.
2. Turn on airplane mode, or disconnect from Wi-Fi.
3. Add another file. It still opens and converts, because nothing needs the internet.

The network tab (on a computer)

1. Open your browser's developer tools (F12, or Cmd+Option+I on a Mac) and choose the Network tab.
2. Add a file to the tool.
3. You'll see the tool's own code load (files from /_astro/), and nothing that sends your file. No upload, no POST requests.

Ads and cookies

ToolkitHere is free because it may show ads. Ads never appear inside or next to your results, and ad code never has access to your files. See the privacy policy for details on cookies and consent.
