Privacy policy

Last updated: October 13, 2026

1. Summary

This site does not ask you to create an account and does not set advertising cookies. We only measure, in aggregate, how the page is used.

2. What we collect

Aggregate usage data through Vercel Web Analytics: pages viewed, country, browser and device type, and referrer. It does not use cookies and does not follow you across sites.
A few interaction events: which chapter of the page was reached, clicks on the early access button, and whether the intro was skipped. These carry no name, email or other personal details.
Technical logs kept by our hosting provider (Vercel), such as IP address and request time, for security and reliability.

3. What we store on your device

The site does not store information in your browser to identify you. Your system's reduced-motion setting is read to choose between the animated and the simple layout, and it is not sent anywhere.

4. Early access

The early access button may take you to a page run by us or by a service provider. Anything you submit there (for example an email address) is handled under the privacy notice shown on that page.

5. How we use the data

To understand which parts of the page work, to improve it and to keep it secure. We do not sell personal data.

6. Sharing

Data is processed by our hosting and analytics provider, Vercel, which may process it outside your country. We share it with others only when the law requires.

7. Your rights

Depending on where you live (for example under Brazil's LGPD or the EU's GDPR), you may ask to access, correct or delete personal data we hold about you, or object to its processing. Because the analytics are aggregate and anonymous, we usually hold no data that identifies you.

8. Changes

We may update this policy. The date above shows the latest version.
