Privacy policy

Last updated: 6 November 2026

The publisher of the site roulekm.fr and of the Roulekm app is named in the legal notice.

On this site

• No cookies. The site sets no cookies and stores nothing on your device.
• No forms, no accounts. You don’t have to type anything to read the site.
• Nothing from other sites. The pages load no fonts, scripts or ads from anywhere else.
• Visitor counts without personal data. We count page views, how far pages are read and clicks to the App Store and Google Play, to learn which guides help. These totals are kept with Cloudflare Workers Analytics Engine, with no IP address, no browser details (user agent) and no identifier of any kind: nobody can tell who read what, or follow you from one page or site to another.
• Hosting. Like any host, Cloudflare receives the technical details it needs to send you the pages, including your IP address. We don’t record them.

In the app

Roulekm asks for no account and no location. Your trips, your vehicles and the logs you export (PDF, CSV) stay on your phone. Their backups go to your own iCloud or Google account, which we never see, or wherever you save the export.

To work and to get better, the app also sends, with nothing that identifies you:

• Your purchases, to RevenueCat, under an ID drawn at random when the app is installed: to unlock Pro and count sales.
• Anonymous usage statistics, to PostHog (hosted in the European Union): which screens and buttons get used, with the app version, the operating system, the language and the number of days since install. Never text you typed, never a trip.
• Crash reports, to Sentry (hosted in the European Union): the error, app freezes, the device model and the operating system version. No IP address, no device name, none of your data.

These IDs belong to the installation and are linked to no person. No ads, no advertising ID, nothing sold or combined with other data. You can turn off usage statistics and crash reports in the app’s Settings, under Privacy (“Share anonymous usage statistics and crash reports”, on by default). Purchases are still needed to unlock Pro.

If you write to us

If you write to support@roulekm.fr, we use your email address and your message to answer you, and for nothing else (our legitimate interest in handling your request). Our email service receives them on our behalf. We keep them while we handle your request and its follow-up. We never sell or share them.

Your rights

You can ask to access, correct or delete your data, restrict its use or receive a copy of it, and you can object to its use (articles 15 to 21 of the GDPR). Write to support@roulekm.fr.

If you think your rights have not been respected, you can complain to the CNIL, the French data protection authority, online at cnil.fr or by post: CNIL, Service des plaintes, 3 place de Fontenoy, 75007 Paris, France. You can also complain to the data protection authority of the country where you live.
