Just a note about privacy, because it's important. My approach to privacy is pretty straightforward: I avoid collecting private information whenever possible.
It’s also important to consider the difference between private and anonymous data.
I’ve chosen to use Plausible Analytics to track usage of websites (including this one) because it does a great job of providing useful data without, in their own words, “collecting any personal data or personally identifiable information (PII), without using cookies and while respecting the privacy of [our] website visitors.” This means that you’re not tracked across devices, websites, and apps.
You can see exactly what I see here.
I do, in some circumstances, collect personal data.
Specifically, if you send me an e-mail, I’ll keep a record of your e-mail address, as well as any communication you had with me, in some form or another. I do this because it’s necessary to communicate with you.
Your e-mail address will never shared be with anyone without your permission, period, unless I'm required to by law — but only after a careful review of the request with legal experts.
