Privacy · Security · Freedom
All your messages will remain only between you and your contact
Two apps. One philosophy. Your privacy, your rules.
Secretum
Private communication in a familiar chat interface through your e-mail
Your e-mail address is all you need for private communication
All messages are sent encrypted and deleted from the mail server immediately after being read by the recipient.
Files deleted after reading
Sent a file — recipient downloaded it — file is gone. No storage on our side.
Three protection codes
Normal access, decoy mode, and panic wipe. For any threat scenario.
No phone number required
Your e-mail is enough. We don't need to know who you are.
Censorship resistant
Blocking us means blocking e-mail entirely. That's not going to happen.
Familiar chat interface
All communication happens in a familiar chat UI. Your messages are stored only on your device.

CloudSecretum
Messaging through cloud storage
Cloud storage is the transport
Google Drive, Dropbox, OneDrive and many others, or through our provided cloud storage.
Censorship resistant
Blocking us means blocking all cloud storages. That's not going to happen.
Server — only for convenience
We use the server only for notifications and contact discovery. All messages are stored only on your device.
Encrypted before upload
The cloud provider sees only encrypted data. And only briefly. Even under request — nothing to read or hand over.
All data deleted from cloud after delivery
Messages and files are removed from cloud storage the moment your contact receives them. Nothing is stored.
Three protection methods
Normal access, decoy mode, and panic wipe. For any threat scenario.
