Overview

Limited assessment

2 finding categories to review

Tor Browser (org.torproject.torbrowser) was scanned at version 15.0.24 (140.17.0esr) on 2026-10-09 but is not graded, because the analysis did not complete enough of its checks for a score to mean anything. The checks that did run recorded 2 finding categories across 22 occurrences; because the analysis did not complete, the absence of anything more severe is not a result. 2 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

lowAmazon S3 bucket reference2 occurrences

Interpretation & review guidance

A reference to an Amazon S3 bucket. Using cloud storage is normal — the risk exists only if the bucket allows anonymous listing/read, which requires a separate authorized assessment.

Evidence
2 recorded occurrences in the analyzed APK. These are distinct stored findings, not a count of every source match.
Verification
Static detection; current reachability is not established.

lowFirebase Storage bucket reference20 occurrences

Interpretation & review guidance

A Firebase Cloud Storage bucket reference (the default <project>.appspot.com). Storing user files here is normal — it's only an exposure if the Storage security rules allow public read/list, which live verification tests.

20 recorded occurrences in the analyzed APK. These are distinct stored findings, not a count of every source match.

Where it can go
Third parties present (1)
Google Firebase Analytics
  • Persistent-identifier APIs referenced in code (Android ID, Device ID / IMEI) with 1 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
  • Camera, Microphone, Photos & files data requested with third-party analytics/ad SDKs present.

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.

Data Safety comparison is not conclusive because analysis coverage is incomplete or unknown.
