Privacy
Effective .
We collect the email address you give us, which edition you picked, and how you found us: the tracking tags on the link you followed and the name of the site that sent you, if any. The page you land on reads these and does not save them on your device. We use the address only to send you Technicals Visualized and to confirm you asked for it, and the rest only to learn which channels bring readers.
When you sign up we also record the country and the network provider (your internet or mobile company) the request came from, as our host, Cloudflare, reports them, and keep them with your email address. We do not save your IP address with your signup; to slow down repeated signups, our signup check keeps only a scrambled count tied to it, for at most a day. We use the country and network provider only to spot automated or abusive signups.
Your address is stored with our email provider, Brevo, which sends the emails and records opens and clicks so we can tell which charts are useful. We do not sell or share your address.
Every email has a one-click unsubscribe link. To have your address deleted, reply to any email and say so.
Website analytics
Pages on this site are measured with Cloudflare Web Analytics, which Cloudflare, our web host, adds to the pages it serves. It counts page views and page-load times in aggregate. Cloudflare states that it does not use cookies or local storage to collect these numbers and does not fingerprint visitors by IP address or browser details (Cloudflare), and that it does not log the query string of the address you visit (Cloudflare FAQ). It stores nothing on your device, and a content blocker can block it without breaking anything on the site.
Do Not Track
Some browsers can send a Do Not Track signal. There is no common standard for how a website should respond to it, so this site does not change what it collects when it receives one. The analytics described on this page runs either way. We do not track you across other websites or build an advertising profile of you, with or without the signal. We do not sell or share personal information, so there is nothing for a Global Privacy Control signal to opt you out of.
Reviewing your information
We hold your email address, the edition you picked, how you found us, and the country and network provider your signup came from. To see what we hold or to change it, reply to any email and say so.
Children
This site is not directed to children under 13, and we do not knowingly collect personal information from them. If you think a child has given us an email address, write to us (reply to any of our emails) and we will delete it.
Changes to this policy
When we change this policy, we post the new version on this page and change the effective date shown at the top. That date moves only when the wording changes.
