Cloud History Sync

Optional, end-to-end encrypted history sync across devices. Your data is encrypted in your browser before upload, and we cannot decrypt it.

How it works

  • Client-side encryption: AES-256-GCM, key derived locally from your account identity; key never leaves your device.
  • Encrypted blobs only: the server stores encrypted history and basic metadata (timestamps, tool name, character counts).
  • Zero-knowledge architecture: we cannot decrypt or read your history.
  • Opt-in: disabled by default; enable in Settings → History & Privacy.
  • Cross-device: sign in on another device, we fetch and decrypt in your browser.

Retention & limits

  • Free (registered): 25 entries per tool, auto-delete after 30 days.
  • Pro: 100 entries per tool, auto-delete after 90 days.
  • Local history: stored in your browser; configurable limit (5/10/25/50/100).
  • Delete anytime: per-tool delete, or delete all cloud history in Settings.
  • Export: local history export (JSON) and cloud history export (all tools) available in Settings.

Privacy notes

  • Do not paste secrets (passwords, API keys, PHI); we cannot decrypt your data, but you should avoid storing sensitive material.
  • Encryption keys are never sent to our servers.
  • Share/Email features are separate, opt-in flows; those send content to our backend briefly.

Quick start

  1. Sign in or create an account.
  2. Go to Settings → History & Privacy.
  3. Enable “Cloud History Sync” and verify connectivity.
  4. Export/delete cloud history anytime from Settings.
