Privacy Policy

Last updated: 2026

We keep data collection to the minimum needed to sell a digital book and run a transparent public experiment.

What we collect

What we do NOT collect

We do not store card numbers, and we do not sell or rent your data to anyone.

How we use it

Third parties

Payments: Lemon Squeezy (our merchant of record; see Lemon Squeezy's privacy policy). Fonts are loaded from Google Fonts and QR codes are generated via api.qrserver.com — these services may receive your IP address. Crypto contributions are made directly to public wallet addresses on their respective networks.

Your rights

You may request that your name be removed from the public wall, or ask what data we hold, by emailing [email protected]. Where GDPR applies, you have rights of access, correction, and erasure.
