Privacy

Your birthday never leaves your device. All the calculations happen in your browser. We don't send your birthday to any server, and we don't store it anywhere except, optionally, in your own browser so the form is filled in next time.

What we collect

• Email address, only if you subscribe to the newsletter or use the contact form. We use it to send what you signed up for, and you can unsubscribe anytime.
• Anonymous usage data, if analytics are enabled: pages viewed, device type and approximate country. We use it to see which pages people find useful.

Advertising and affiliate links

Some pages may show ads from Google or other ad partners, who may use cookies to show relevant ads. You can control personalized ads in your Google ad settings. Some links to stores are affiliate links, which means we may earn a small commission if you buy something, at no extra cost to you.

Sharing

Share images are created on your device. Nothing is uploaded unless you choose to share it yourself.
