Zero Cloud Transmission • Air-Gapped Ready • Open Scoring Math

Trust, Verification & Methodology

The Android Privacy Auditor was engineered with an absolute privacy premise: you should never have to sacrifice confidentiality to audit application security. We prove this mathematically, architecturally, and cryptographically.

Zero Outbound Network Requests

All analysis engines (manifest parsing, DEX bytecode inspection, signature matching) run completely in local memory on your machine.

Ephemeral Processing Guarantee

Uploaded APKs are handled via temporary files with auto-purging semantics. APK files are never permanently stored, cataloged, or executed.

Cryptographic Passport Trust

Reports generate canonical JSON digests signed with Ed25519 asymmetric keys, allowing third parties to independently verify report provenance without contacting our servers.

How the Analysis Pipeline Operates

[1] User Browser → Local HTTP POST (multipart/form-data) → FastAPI backend (127.0.0.1:8000)

[2] Python Androguard Engine → In-memory ZIP & DEX unpack → Direct Dalvik VM bytecode inspection

[3] Offline Signature DB → 428 Exodus signatures loaded from local disk → Instant string matching

[4] Privacy Passport Engine → Canonical JSON hashing + Ed25519 signing → Instant browser render

Notice there are zero external API calls, no analytics trackers embedded in our UI, no Google Analytics, and no telemetry pings.

Verified Local Execution Guarantee

All APK processing remains strictly on your device.
