In the late 1990s hobbyists exchanged short messages using simple substitution ciphers embedded in SMS gateways. These early experiments offered obscurity but no real secrecy, as anyone with basic decoding tools could read the content. Nonetheless, they sparked the idea that text could be detached from identity, laying groundwork for later privacy‑focused services, and attracted a small community of privacy enthusiasts who shared code snippets online.
The early 2010s saw the emergence of dedicated anonymous texting apps that stored messages on remote servers without logging phone numbers. Companies marketed these tools as “burn after reading” services, promising that messages self‑destruct after a set interval. While server‑side anonymity improved, users still faced risks from metadata leaks and jurisdictional data requests, prompting a push for stronger client‑side encryption, and the development of open‑source libraries to verify security claims.
