we do not share your data with anyone and there are many ways to control the visibility and storage life of your data here.
but the internet is a public space and you should always assume your data could be compromised.
be smart with your password, use tor or a vpn, and use pgp for sensitive communications.
If a particular postman on your route likes a puff he will have it every time.. If I were you, use a trusted vendor for stealth especially (read reviews) and defo a trusted address you can send it to instead? Hope this helps? :)→
