Privacy policy

Your measurement files

Files you open are read in your browser tab and are never sent to a server. This is not a setting that could change: the site has no function that receives a file, and its Content Security Policy forbids the page from sending data to any other site. The security page explains how to check it yourself.

Data controller

Baptiste Guilleux EI, Tours, France, SIRET 109 247 007 00015. Contact: contact@kymogram.com.

What the site counts

No account exists and no script from another domain is loaded. To know whether the tool is used, the page sends the name of a few events, such as “a file was opened”, and the server adds one to a counter for that event and that day. No IP address, no identifier, no time of day and nothing stored on your device: only daily totals exist, and nothing can recognise you from one visit to the next. The full list of events is on the security page.

The host also processes technical data such as your IP address, to deliver the pages, to limit the number of requests to the counting service, and to protect the site against attacks. It keeps it for a limited period of its own. The site keeps no request log.

Legal basis: legitimate interest in knowing, anonymously, whether the tool is used, and in keeping the site working.

The former waiting list

A waiting list for a paid version was open from 23 September to 2 October 2026. Everything is now free and the list is closed: no address is collected any more, and the addresses left on it have been deleted without being used.

Emails you send

They are kept for as long as it takes to answer, then archived for three years at most.

Your browser

Your browser keeps the application's files, so that it works offline, and your choice of light or dark mode. Nothing is stored on your device for counting or tracking, which is why there is no consent banner.

Recipients and transfers

The only third party involved is the host, Cloudflare, Inc. No data is sold, exchanged or used for advertising. This provider may process data outside the European Union, on the basis of the European Commission's standard contractual clauses.

Your rights

You have the right of access, rectification, erasure, objection, restriction and portability, and you can withdraw your consent. Write to contact@kymogram.com, with no reason to give: an answer is owed within one month. You may also lodge a complaint with the French data protection authority, the CNIL (www.cnil.fr).
