Example: All data you type in for account registration but do not for purchase.
Easyer tracking directly and indirectly. Data broker use all they can get to identify you, so cross site tracking happens whenever you provide same phone number or mail.
Being able to switch these data points is helpful for privacy. And switching is easyer without accounts.

Decentralized services habe one huge advantage: Most people don’t unterstand, how it works, where to register and do on. Additionally federation comes with lots of additional to get most of connections.
Therefore: Centralized is definitely the way but not using shitty big tech. Maybe backup infrastructure could also be a way.
And Proton? Couldn’t stop laughing.

When confronted, the developer claimed screenshots were only taken of suspicious sites and were encrypted
??? What’s the point? If you collect sensitive data, it doesn’t matter if you transfer them encrypted or not. What a bullshit argument. You still collect it.
I wonder if he is ashamed of himself.
More context please. Where did you set the DNS? Smartphone, desktop? In browser or on system settings?
Assuming the following: You set the general DNS on your AOSP based smartphone to Mullvad and use Tor bowser simultaneously.
This is perfectly fine as Tor browser uses its own DNS. They won’t interfere.
If privacy is your topic, iPhones are out.
You could check /e/OS for example with Fairphone that includes parental control feature.
Your parents do not matter in this context and it would be shameful to use such features.
Avoid tracking apps and tracking in apps. Avoid big tech like Meta and use Signal instead. If your child is not willing to do without Tiktok, Insta and so on, you won’t prevent. You can only explain. Remember: Divice literacy is not media literacy
I only know two visble options in terms of credibility and costs per feature ratio: Posteo and mailbox.
Proton should be avoided since their descructive behaviour regarding critique and their baclground. Tutanota is to be avoided since they only support their own client. That leaves us with no flexibility and a smack of something.
