Features

Every feature your encrypted vault needs.

10 powerful features that work together — no bloat, no plugins, no configuration hell. Write, encrypt, search, share, sync.

Encryption

Encrypt anything, anywhere in your notes.

Secret blocks are AES-256-GCM encrypted containers that live inline with your markdown. Drop one into any page — a login, an API key, a credit card — and it's encrypted at rest with a unique nonce. Everything else on the page stays plaintext and searchable.

Key behaviors

  • Click to reveal, click to copy
  • Auto-hides after 30 seconds
  • Clipboard cleared after 30 seconds
  • Unique nonce per block — no two encrypted alike

# API Design Notes
 
## Authentication Flow
Use OAuth2 with PKCE for all public clients.
 
rust
pub fn verify_token(token: &str) -> Result<Claims> {
let key = decode_key("RS256")?;
jsonwebtoken::decode(token, &key, &validation)
}
 
## Rate Limits
 
Endpoint Limit Window
/auth 10 1 min
/api/v1/* 100 1 min
/search 30 1 min
Versioning

Every save is a commit.
Every change is recoverable.

Claspt uses a real git repository under the hood — not a custom undo stack, not a database of snapshots. Every time you save a page, it's committed. You get full history, meaningful diffs, and the ability to roll back to any point in time.

  • Auto-commit on every save — no manual steps
  • Full version history with date, time, and diff
  • One-click rollback to any previous version
  • Push to remote git repos Pro

Organization

Folders, tags, and
everything in its place.

Your vault is just a folder on disk — no proprietary database, no sync conflict nightmares. Organize with nested folders up to 5 levels deep, add tags with autocomplete, pin important pages, archive what you don't need right now, and duplicate anything in one click.

  • Nested folders — up to 5 levels deep
  • Tags with autocomplete — create, filter, and search by tags
  • Pin pages to the top of any folder
  • Archive pages without deleting them
  • Duplicate any page in one click
  • Assign emoji icons to folders for visual identification

Biometric

Your face or your fingerprint.
Your choice.

Claspt integrates with your operating system's biometric authentication — Touch ID on macOS, Windows Hello on Windows, fingerprint sensors on Linux. Your master key is stored in the OS keychain and unlocked only via biometric verification. No biometric data ever leaves your device.

Three modes

Disabled

Password only — classic mode

Re-auth

Biometric to reveal secrets only

Primary

Biometric unlocks the entire vault

Sync Pro

Your vault, on every device.

Sync your vault across macOS, Windows, Linux, iOS, and Android using the backend you already trust. Your data never touches our servers — it goes directly from your device to your storage provider, encrypted in transit and at rest.

Git Remotes

GitHub, GitLab, Bitbucket, or any git server

iCloud

Native Apple integration for macOS and iOS

Google Drive

Works with personal and Workspace accounts

Dropbox

Folder-based sync with conflict resolution

WebDAV / SFTP

Self-host with Nextcloud, Synology, or any server

Claspt sync backend settings — Git, iCloud, Google Drive, WebDAV, SFTP
Security guarantee

Secret blocks are encrypted before they leave your device. Your sync provider stores ciphertext only — they cannot read your secrets even with full access to your files.

Import

Bring your secrets from anywhere.

Migrating from another password manager? Claspt imports your data and converts it into encrypted secret blocks — ready to use in minutes, not hours.

LastPass CSV export
1Password 1PUX / CSV export
RoboForm CSV export
KeePass KDBX / CSV export

How it works

1
Export

Export from your current manager in CSV or native format

2
Import

Drag the file into Claspt — automatic field mapping

3
Review

Verify imported entries, fix any mapping issues

4
Delete Export

Securely delete the unencrypted export file

Sharing Pro

Share secrets without
compromising security.

Sometimes you need to send a credential to a colleague or a family member. Claspt lets you share entire pages or individual secret blocks — password-protected, time-limited, and optionally self-destructing.

  • Password-protected sharing — send entire pages or individual secret blocks
  • Configurable expiry: 1 hour, 24 hours, 7 days, or 30 days
  • Burn-after-reading: auto-delete after first access
  • Share password sent separately (phone, text) for true security
  • Email notifications when a share is accessed (optional)
  • No third-party service — shares go through the Claspt relay, encrypted end-to-end
Pro Claspt sharing dialog with password protection, expiry, and burn-after-reading
