Privacy

Last updated: 29 October 2026.

In short: no account, no cookie, no ads. Grids are built in your browser and nothing you generate is sent anywhere.

What stays on your device

The site stores in your browser’s local storage (localStorage) the last settings of each generator (size, difficulty, number of grids, paper), plus the dates of your first and last visit, to count returns without tracking you. This data is never sent: you can erase it by clearing the site’s data in your browser. The word lists you type (word search, crossword) never leave your browser.

Audience measurement (Umami)

To learn which tools are useful, we use Umami, a cookieless analytics tool. It counts, in aggregate, page views, the site you came from, country, device type and a few events: grid generated (tool and settings, never the content), PDF downloaded, days since first visit, click on the “Bug or idea?” link. No persistent identifier is set, your IP address is not stored, and your browser’s “Do Not Track” setting is respected. Data is hosted in the European Union and kept for 6 months.

Error tracking (Sentry)

When a technical error happens, Sentry (Functional Software, Inc.) receives a report: error message, browser, page and site version. Personal data collection is disabled and there is no session recording. Data is hosted in the European Union (Germany) and kept for 30 days.

Hosting (Cloudflare)

Like any host, Cloudflare processes your IP address while serving the pages and protecting the site against attacks.

Your rights

You can ask to access or erase data about you, or object to audience measurement, by writing to ludocade1@gmail.com. You can also contact the French data protection authority, the CNIL.
