Dust

Dust offers self erasing encrypted messaging for true privacy

Dust is built around a simple idea: what you say should not haunt you forever. Co-founded by Mark Cuban, this secure messenger focuses entirely on protecting your conversations from prying eyes, data mining, and casual snooping.

The core experience is familiar: you can send texts and photos to friends, family, and colleagues. What sets Dust apart is how aggressively it treats your privacy. Messages are heavily encrypted end to end and are automatically erased after 24 hours, so your chat history never lingers longer than it needs to. If you regret something you sent, the unsend feature lets you delete it not just from your own screen, but from the recipient’s as well, in real time.

Dust also takes screenshots seriously. If someone tries to capture your conversation, the app will detect it and alert you, discouraging people from keeping permanent records of what was supposed to be a private exchange. For those who share sensitive details such as bank data or passwords, this extra layer of transparency is particularly reassuring.

The interface is clean and focused, with security options clearly emphasized rather than buried in menus. However, the same strengths can feel limiting. If you like keeping long-term conversation histories, searching old chats, or backing up messages, Dust’s auto-delete approach will be a downside. And because both parties need to use Dust to benefit from its protections, it works best within a circle of privacy-conscious contacts.

Overall, Dust is an excellent choice for anyone who prioritizes confidentiality over convenience. It does not try to replace all-purpose messengers; instead, it excels as a dedicated, private space for conversations you never want stored, mined, or resurfaced.
