Sensitive areas take a second lock of your choosing. There is no reset and no backdoor — a vault we could open for you is a vault we could be compelled to open for someone else.
Every block is yours to shape — colours, gradients, fonts, corners, alignment, custom fields. Nothing looks like a template because nothing is one.
Your profile screen goes only to the contacts you grant access to. Everything else stays private until you deliberately publish it.
Publish an individual block, or gather several into a stack. Both are found through search, and both are yours to unpublish at any time.
Encrypted Vault
Notes, credentials and sensitive data in a local vault encrypted with AES-256-GCM, unlocked by an Argon2id-derived key that never leaves your device.
Post-Quantum Messaging
Sessions established with a hybrid ML-KEM-768 and X25519 handshake, then advanced by a Double Ratchet with per-message keys and Ed25519 signatures.
Profile Screen
A private page delivered only to the contacts you grant access to, encrypted per recipient. Nobody else can request it or read it.
Public Blocks & Stacks
Publish individual blocks, or ordered stacks of them, to a public surface others can find and follow. Publishing is always a deliberate act.
Encrypted File Transfer
Relay sends files to a contact encrypted end to end. Drive keeps your own files encrypted at rest, and Safety Deposit Box backs the vault up on paid tiers.
Key Pair Management
Create and manage cryptographic key pairs for encryption, signing and identity, alongside secure password generation with configurable rules.
Built
Identity and transport, encrypted messaging, storage and file transfer, public publishing, and search are implemented and running on device.
In Progress
Final hardening and multi-device testing ahead of submission to Google Play.
Release
Availability will be announced by JC Laboratories. Write to us and we will let you know once, when it ships.
