Metadata
Metadata is data about your data — who you contacted, when, from where, and how often — which can reveal almost as much as the content itself, even when the content is encrypted.
What it means
Metadata is the information surrounding your data rather than its content: the sender and recipient of an email, timestamps, file sizes, IP addresses, and frequency of contact. It is generated automatically by almost everything you do online.
Why it is sensitive
Even with perfect content encryption, metadata can expose who you talk to, when, and how often — enough to map your relationships, routines, and location. "We kill people based on metadata," as one former intelligence chief put it.
Why it matters
Real privacy means minimizing metadata, not just encrypting message bodies. A service that encrypts content but logs everything around it still knows a great deal about you.
How Atomic Blend approaches it
Atomic Blend encrypts your content end to end and is built to collect as little metadata as possible — no ads, no profiling, and a self-host option that keeps even operational data on your own infrastructure.
