Privacy Policy
Last updated October 6, 2026.
Your contract stays on your device
Your name, rules, motto and daily check-ins are saved in your browser's local storage so the tracker works without an account. They are never sent to our server. Clearing your browser data deletes them. The money saved calculator runs in your browser too; the numbers you enter are not sent anywhere.
Usage measurement
We run our own first-party analytics: we count page views and feature use (for example "printed a contract", "saved a wallpaper" or "used the money calculator") to learn which features help. Each event records the page, the referring site, a random visitor ID kept in your browser, your country as reported by our hosting provider, and whether you are on a phone or a computer. It does not include your contract text, the numbers you type into the calculator, or your IP address. No third-party analytics service is used. Our site is hosted on Cloudflare, which processes requests to deliver the site. Fonts are loaded from Google Fonts, so Google receives a request from your browser when a page loads.

Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet.
