Klargrid

Your workbooks do not leave. Check it yourself.

Your files stay on your device, and you can check it in thirty seconds. This page explains how.

Three checks

  1. The Network tab

    Open your browser's developer tools (F12), Network tab, then drop a file and run a tool. You will see the page's scripts loading, and no request carrying your data.

  2. Airplane mode

    Load a tool page, turn off the network, then work: everything keeps working.

  3. The security policy

    View the page source: the Content-Security-Policy tag carries connect-src 'self'. The browser refuses any connection from the page to another domain, whatever code it runs.

The content security policy

It is the same on every page of the site: default-src 'self', connect-src 'self' blob:, form-action 'none', frame-src 'none', object-src 'none'. No font is loaded from a provider, no script from a CDN, no analytics.

The site's only request

After a save, your browser sends this domain a request containing only a tool family ("workbook" or "data") and a number of files: POST /compte?f=classeur&p=1. Nothing else: no file name, no content, no cookie.

The matching log records only a date, the family and that number: no IP address, no user agent, no referrer. A browser that asks not to be tracked (Global Privacy Control, Do Not Track) sends nothing, and a failed send is silent: it never prevents a save.

And the GDPR

Klargrid processes none of the personal data in your files: it never receives them. So there is no processor to declare, no transfer outside the European Union, no data processing agreement to sign, no retention period to set. The tool is not part of the processing.

What we do not guarantee

  • Your browser and its extensions. An extension allowed to read pages can read what they show, here as anywhere.
  • Your machine. Spyware installed on it sees what you see.
  • What you do with the output file. Once saved, it is yours: if it then leaves by email, that is beyond our reach.
