What happens when every time your browser sends data to a tracker it makes a beep sound? Well, @bert_hubert did just that. And it sounds like you are listening to an old school modem. Creepy stuff! https://berthub.eu/articles/posts/tracker-beeper/
Tracker Beeper - Bert Hubert's writings

A week ago, I finally got round to implementing an idea I’d been toying with for years: what if your computer made a little bit of noise every time it sent data to Google? From studying logs, I’d long known just how many sites send all your visits and clicks to (at least) Google, but a log that you have to manually create first and then analyze is not very dramatic.

@jwildeboer @bert_hubert 2 weeks ago i started using a dashcam app on my smartphone. It called out so frequently whilst being blocked by duckduckgo's app tracking protection that my smartphone drained battery and shut down overheated. Lesson learned: app tracking protection works
@SchepBernard @jwildeboer @bert_hubert Consider a DNS based blocker such as AdGuard DNS. It blocks trackers without having to run anything on the phone.
@Lulukaros @SchepBernard @jwildeboer @bert_hubert This is for AdGuard, but works similarly for others, too: https://adguard-dns.io/en/public-dns.html
AdGuard DNS — ad-blocking DNS server

Create your ad-blocking DNS server that will protect your personal data, prevent tracking and allow you to control access to specific content on the Internet.

Connect to public AdGuard DNS server
@sesivany @Lulukaros @jwildeboer @bert_hubert Thanks, Jiri. I tried to but backed of since it only supports Yandex and Samsung browser. Why no Firefox for instance?
