Privacy
Klods doesn't ask for an account and sets no cookies. Here is what is kept, where, and for how long.
Your progress stays with you
Your progress (current step, build time, parts marked missing), the sets kept for offline use and your settings stay in your browser. Nothing is sent to a server.
To erase everything, clear this site's data in your browser.
Feedback you send
When you send feedback, we keep your message, its type, the set, model and step it's about, the page it comes from, your browser (to reproduce a bug) and, if you give it, your email address. Your IP address isn't recorded.
Feedback is only used to fix the site and the models. It's kept for one year at Cloudflare (Workers KV), then deleted automatically. A copy is emailed to the person who runs the site.
Audience measurement
Klods counts its visits with Cloudflare Web Analytics: no cookies, no identifier, no tracking from one visit to the next. We see page views, the most read pages and the type of device, never who you are.
Hosting
The site is served by Cloudflare, which processes your IP address to deliver the pages and protect the site, and may keep technical logs for security.
Your rights
The data controller is Nicolas CABOT-SAVIN. You can ask to see, correct or delete feedback you sent: write to contact@klods.app with the date and the email address you used, if any.
If you think your data isn't respected, you can complain to the French data protection authority, the CNIL (cnil.fr).
