One workspace.Every key stays yours.
Pick the tool that fits the job. Sealing and opening happen on your device, records live on Robinhood Chain, and every action that writes anything asks your wallet first.
Vault
Turn notes and files into AES-256-GCM ciphertext on your device, locked by a passphrase or a key you make.
Nothing leaves your device
Secure Share
Send a sealed file with a link whose key lives only after the #, never on a server.
Optional site storage
Key Management
Generate keys, export them wrapped with a passphrase, and rotate files to a new key.
Runs in your browser
Access Permissions
Record who may read a sealed file: grant, expire and revoke addresses on Robinhood Chain.
Your wallet, plus a little ETH for gas
Onchain Records
Check a sealed file or record id against the chain: owner, time, grants and status.

The Vault, Secure Share, Key Management and Onchain Records need no wallet at all. Access Permissions needs one, because anchoring and granting are transactions you sign and pay gas for.
Encryption protects contents, not metadata: sizes, timing and the addresses you grant on chain stay visible. Read the documentation for how each tool handles data and where its limits are.
