Privacy Policy

Effective: January 1, 2026

1. Information We Collect

This site does not require registration. Bookmark data is stored only in your browser (localStorage). The only personal information we collect is an email address, and only if you voluntarily provide one (see Section 4).

2. Analytics

We use Google Analytics for service improvement. Anonymous visit statistics (pageviews, session duration, etc.) are collected.

3. Advertising & Cookies

This site displays ads served by Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads based on a user's visit to this site and/or other sites on the internet.

You may opt out of personalized advertising by visiting Google Ads Settings. You can also opt out of third-party vendor use of cookies for personalized advertising by visiting www.aboutads.info. We also use functional cookies for language and theme preferences.

4. Mailing List (Optional)

When downloading a PDF cheat sheet, you may optionally provide your email address to receive occasional updates about new platforms and features. Providing an email is never required — downloads work without it. If you subscribe, we store only your email address, the page you subscribed from, and the date. We do not share or sell this list. You can unsubscribe at any time by emailing us (see Section 5), and we will delete your address.
