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.
Sufficient measures can be taken to counter that surveillance. The internet is not broken, it's just not compatible with the concept of nation states and their urge to tax and judge their citizens by continuously gathering and demanding more information about their citizens, assets, beliefs and whereabouts.
Anonymous Peer to peer sharing and peer to peer transactions void the concept of nation states, as peers can be anywhere. Their nation is the swarm in which they participate. Their legislation is an algorithm. Their identity is none.
What we are seeing now is the end of an empire, it struggles to stay relevant and attempts to take or violate certain away human rights. That is not sustainable.
you and your recipients must use pgp software and publish your "public keys" in order to communicate with each other. use the edit function on your little biggy page to publish your key. you can personally encrypt and decrypt private q & a's on little biggy by using this technique.
using a web site to gen your private key is like asking a criminal to install new locks on your house for you. install pgp or gpg and generate your own key on your own computer otherwise you're being scammed. ex: generate key: gpg --gen-key print public key: gpg -a --export (copy-paste and paste into littlebiggy)
