Anddd… You use wifi to connect to their servers, so they’ll have your residential ip (unless you got a VPN on at all times… And even then there’s probs some way to fingerprint you enough). Partner uses the same wifi network and your profiles are linked again…
There really just is no way to completely escape. Blocking all ads and trackers on a DNS level (using a pi-hole or external service like nextdns[paid, but its pretty good]). Is a good solution though, at least you won’t need to actually see ads
I use it all the time for the one time use cards, and it’s been effortless to use.
The data breach is of course bad, but no company is completely immune to those.
Privacy policy… Is not a great look (especially with the marketing being opt-out and having a convoluted process…) I honestly hadn’t heard about it. But even now I’ll continue to use it because weighing the marketing vs my CC details out there is still not a hard choice.
Depending on where you live Revolut might be an option for you. Unlike privacy.com its basically just an online bank where you can open an account and send money to/from, but they offer a one-time-use credit card (which changes every time you use it).
Simply making the hash really hard is not a good option. All most people will notice is that their underpowered phone suddenly takes way longer to unlock compared to before. Cracking the hash on very powerful hardware is then ‘trivial’
As the other comment mentioned, a hardware solution seems to be the only one.
It’s like enabling https on your website with a self-signed certificate. Cool but worthless as an indication of validity to anyone but yourself.
