Quick answer

Tor onion search aggregator. Privacy-first, RAM-only, no tracking.

Ghost is a privacy-first Tor onion search aggregator for Android. It queries 13 public onion search engines in parallel, deduplicates and ranks the results, and opens links externally in Tor Browser.

KEY FEATURES

• 13 onion search engines queried in parallel • RAM-only session — no queries, results, or history written to disk • Three purge triggers: panic wipe, screen lock, app exit • VPN gate — non-dismissible, blocks queries unless Orbot VPN is active • Tor SOCKS5 transport with remote DNS via Tor • FLAG_SECURE — blocks screenshots and recents thumbnails • No backend, no telemetry, no accounts, no ads • Stop button to cancel running searches • Consent gate with 18+ verification, shown every session • External link handoff to Tor Browser

PRIVACY

No data collected, stored, or transmitted to any server. Queries and results exist only in RAM during the active session. Only three non-sensitive preferences persist across sessions: engine selection, snippet filter, VPN requirement.

The app never renders remote HTML. Links open externally in Tor Browser via intent. Screenshots and recent-app previews are blocked.

REQUIREMENTS

• Android 7.0+ (API 24) • Orbot in VPN mode (for Tor transport) • Tor Browser for Android (for opening result links)

HOW IT WORKS

1. Enter a search query 2. Ghost queries 13 onion search engines in parallel via Tor 3. Results are parsed, deduplicated, and ranked 4. Tap any result to open it in Tor Browser 5. When you lock the screen, exit the app, or hit panic — all session data is wiped from RAM

What’s new

v4.1.0 — License change and security hardening

License: starting with this release, Ghost Search is distributed under
GPL-3.0-or-later (releases up to and including v4.0.1 remain under MIT).

New in this release:
- Signed engine registry: engine list verified at runtime against the APK
signing key; search refuses to run if the registry fails verification.
Registries now carry a sequence number with rollback protection — a
tampered or replayed registry is rejected.
- Request fingerprint al

How to install

  1. Download the APK from the button at the top of this page.
  2. Allow “Install unknown apps” for your browser or file manager only, not for every app.
  3. Open the downloaded file and confirm the installation.
  4. If installation fails with “App not installed,” remove an earlier build of the same app first. A signature conflict is the usual cause.

Data safety

  • Every file is checked against its published SHA-256 before it is listed.
  • Files are scanned for malware on every update.
  • The permissions each app requests are listed on its own page.
  • Read the full safety policy for how we test, flag, and delist files.
