FastVPN - Fast & Unlimited VPN
T2Dev · Build 3.0.4
Static checks identify review items, not a guarantee of safety.
Overview
2 finding categories to review
FastVPN - Fast & Unlimited VPN (app.t2dev.fastvpn) scored grade A, 99 out of 100, in a static scan of version 3.0.4 on 2026-10-12. It has no high or critical findings, and 2 lower-severity finding categories across 2 occurrences. 7 tracking SDKs are present in the package, which describes what ships, not what runs or what it sends. This is static analysis of a single build: it does not observe the app running and does not establish that any data is exposed.
Start with these findings
lowGoogle API key (client-shipped; restriction unverified)1 occurrence
Interpretation & review guidance
Android apps are designed to ship Google API keys in the client; Google restricts them by app signing certificate + enabled API. This is only a problem if the key is left unrestricted — presence alone is expected, not an exposure.
- Evidence
- 1 recorded occurrence in the analyzed APK. These are distinct stored findings, not a count of every source match.
- Verification
- Static detection; current reachability is not established.
infoApplication data is backup-enabled1 occurrence
Interpretation & review guidance
The app allows Android backups (android:allowBackup="true"). App data can then be extracted via adb backup on many devices — a concern if the app stores tokens or personal/health/payment data locally. Common and low-severity, but worth disabling for sensitive apps.

Privacy signals
Capabilities and bundled software do not prove that data was collected or transmitted.

Data collection & flow (privacy signal, not part of the grade)
- Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI +2 more) with 5 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
This maps what the app can access (permissions it requests, identifier APIs its code references) to the third parties bundled in it. It reflects capability and SDK presence — not proof that a specific value was transmitted.

Embed the latest grade
Embed this grade
The badge reads the latest recorded grade each time it is loaded, and links back to the full report so a reader can see the build it covers and what the scan could not see.
Grades can move when a new version is scanned or when a detector is corrected. If you would rather publish a grade that cannot change under you, link a signed Proof Capsule instead.
API users can request authenticated, scan-specific exports at /v1/scans/e3eaad62-7813-43f2-b56a-0902c70e6a10/findings.sarif (also coverage.json and proof.json).
