Privacy

What this site does not do

This site has no accounts and no forms. It sets no cookies and carries no advertising trackers.

Counting visits

Visits are counted with Vercel Web Analytics, which works without cookies and does not identify visitors. The links printed in our notebooks and those shared on our channels carry a label, for example the notebook’s code. The label is used to count the visits each link brings and says nothing about you.

Technical data

Like any website, the host processes technical data, including your IP address, to deliver the pages and keep the service secure.

Typefaces

The typefaces are served from this site. No request is sent to a font provider.

The Serenity+ app

The app has its own privacy notice, shown on its page in each store.
