Then there is my #dataprivacy longseller "Dann haben die halt meine Daten. Na und?!" which I'm updating about every one and a half years – at least in German. With lots and lots of practical how-tos for securing one's computer and phone, using encryption etc. And a hands-on approach on explaining, why all that matters. The updated English version, "Easy Ways to be More Private on the Internet", is overdue and I hope to finalise it this spring. #NaUndDasBuch #PrivacyBook
