Privacy is the precondition for everything else.

A conversation is the smallest unit of trust between two people. For most of history it was ephemeral by default — words in the air, gone the moment they were spoken. Then we moved our conversations onto wires we don't own, routed through machines that keep perfect copies, owned by companies whose business is to read.

We were told this was the price of convenience. It was not a price. It was a transfer — of leverage, of memory, of the quiet certainty that what you say to one person stays between the two of you.

“If you have nothing to hide” is a sentence only ever spoken by people who have never been watched.

Blink starts from a different axiom: the contents of your conversations are yours, full stop. Not yours unless subpoenaed. Not yours unless it's commercially inconvenient. Yours — sealed by mathematics that we did not invent and cannot weaken, on a network with no center to capture.

We are honest about the edges. Metadata is hard. A compromised phone is unwinnable. We do not promise anonymity; we promise the confidentiality of content, and we show our work. Every claim on this site maps to a primitive you can name and a build you can reproduce.

This is not a revolution. It is a return — to the default that existed before we forgot it. Words in the air, for the two of you, gone unless you choose to keep them.
