Privacy

Short version: we collect almost nothing, we sell nothing, and the interactive tools run in your browser.

What we collect

• Analytics. We use Google Analytics 4 to understand which guides get read. IP-based location is coarse, and we do not build user profiles or run advertising.
• Email, only if you give it. If you subscribe, we store your email address and which page you subscribed from, protected by Cloudflare Turnstile to keep bots out. We use it to send what we promised and nothing else. Every email includes an unsubscribe link, and unsubscribing removes you.

What we never collect

• Your photos. Quizzes and calculators on this site run entirely in your browser. Answers and measurements are processed on your device and are not transmitted to us.
• Quiz results. If you take a quiz, the result can be remembered on your own device (localStorage) so the site can show you relevant guides on a return visit. It stays on your device; clearing your browser data removes it.

Cookies

No advertising cookies, no third-party trackers beyond the analytics described above. Turnstile sets what it needs to tell humans from bots on our forms.

Requests

Want your email deleted, or want to know what we hold about you (it is at most one row)? Write to [email protected] and we will handle it promptly.
