Personal data

The site asks for no account and sets no cookie. The only data processed are the following.

• Your diagrams stay in your browser (local storage). They are never sent to a server, unless you export them yourself or create a share link.
• Share links: “Copy a share link” sends the diagram (its name included) to the server, which keeps it at Upstash through Vercel, under a code known only to those who have the link. It is deleted one year after the link was last opened. To limit abuse, the number of links created from one IP address is counted for one hour, in an encrypted form (a hash), then erased. To have a shared diagram deleted sooner, write to us through the Feedback form, giving the link.
• Feedback form: your message, the contact address if you give one, the language of the page and the type of your browser are sent by e-mail to the publisher, through the Resend service (United States). They are used only to read your feedback and answer you, and are deleted when no longer useful. Legal basis: your consent, given by sending the message.
• Audience measurement: Vercel Web Analytics counts page views in aggregate, without cookies and without any identifier kept from one day to the next.

You have a right of access, rectification and erasure of your data, which you can exercise through the Feedback form. You can also lodge a complaint with the CNIL, the French data protection authority.
