Privacy

Short version: the demonstration sends nothing, and the contact form is the only place on this site that receives information from you.

The demonstration

The library on the home page is compiled to WebAssembly and runs inside your browser. The column you paste, drop or generate is processed in your own device's memory. It is not uploaded, not logged and not seen by anyone — there is no server on the other side to send it to.

That is why you can test with data you would not normally share. If you want to verify the claim rather than trust it, open your browser's network panel while you use it, or download the single-file version and run it with the network disconnected.

The contact form

If you write to us, we receive what you type: name, e-mail, and whatever you put in the message and the qualifying fields. It is used to reply to you and to evaluate a possible commercial licence — nothing else. It is not sold, not shared, and not used to build a marketing list.

The form is delivered by a third-party form service, which handles the message in transit, and it arrives in an e-mail inbox. Ask and we will delete your message and your details; ask and we will tell you what we hold.

Cookies and measurement

This site sets no cookies and runs no advertising or cross-site tracking.

Hosting

The site is served as static files by a hosting provider, which — like every web server — records ordinary request logs including IP addresses, for security and operation. We do not combine those logs with anything else.

Your rights

Under the Brazilian LGPD and the European GDPR you may ask for access, correction or deletion of your personal data. One message to the address below is enough.

Controller: Carlos Alberto Terêncio de Bastos. Contact: the address on the contact page.
