What stays on your device

Your settings and anything you type into the tools are saved in your browser's local storage, on your device only. Clearing your browser data deletes them. We never receive them.

What reaches our servers

Nothing you type or upload is sent to our servers: the tools run entirely in your browser.

Audience measurement

We use Umami, a cookieless open-source analytics tool to count visits and understand which tools are useful. It sets no cookie and stores nothing on your device. It records the page address, the referring site, your browser, operating system, device type, screen size, language and country. Your IP address is used only to derive the country and an anonymous visitor identifier (a salted hash that changes regularly); it is not stored. We also count anonymous tool events, such as "a PDF was downloaded", never what you type or upload. These statistics are used only by us, are not shared or sold, and cannot identify you, so no consent banner is required.

Hosting

The site is hosted by Vercel Inc., 440 N Barranca Ave #4133, Covina, CA 91723, USA, which processes technical logs (IP address, user agent) for security for a limited time.

Your rights

Under the GDPR and US state privacy laws you may ask for access to or deletion of any data about you by writing to hello@99m.fr. You can also lodge a complaint with the CNIL (France).
