American corporations like Facebook, Google, and Amazon make billions from weaponizing your private data. And you don’t even have to be using their products for them to steal from you!
Rob them of that option by blocking ads and trackers.
Starve these bastards of your data, and you’ll kill their revenue.
If you are up for some self-hosting, pi-hole can block some ads, and whatever domain names you’d like. Just have to set your device’s DNS to its IP address. Some ads will get through but it can block a large amount of them.
For android on a per app basis, I use the pro version of NetGuard to block some apps from connecting to ad and tracking domains, or if an app has no good reason to connect to Facebook, etc.
If you have a pixel android phone, GrapheneOS is a great OS to limit what data is sent off to Google.
Alternative self-host solution that does not require a pi.
Get hold of a functioning spare pc with any os that can run docker containers ( highly recommended proxmox for server and opensense for diy router but that may be to advanced) but most os incl windows should work.
Install adguard home in a docker container. Its a dns based blocker like pihole above. Just set your devices to its ip for dns.
Want it on the go? If you have an internal vpn (wireguard) you can set it up so your tunneling al your traffic from home with all protections persisting.
I have not found a way on ios to block those last pesky ads that adguard misses but its still day and night difference.
FYI, pihole can run in docker on any device, not just a pi.
