Startpage Private Browser
Startpage Developers · Build 154.0.8037.126.129
Rescanning re-reads this build; it does not re-check any backend referenced inside it.
Static checks identify review items, not a guarantee of safety.
Backend checks: 39 unauthenticated read checks against backends referenced in this build — 31 refused access, 8 could not be determined. Each check describes one request at the recorded scan time and does not establish the backend's current state. An undetermined result is not evidence that the backend is closed.
Overview
2 finding categories to review
Startpage Private Browser (com.startpage.app) scored grade A, 98 out of 100, in a static scan of version 154.0.8037.126.129 on 2026-11-10. It has no high or critical findings, and 2 lower-severity finding categories across 22 occurrences. 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.

lowExported content provider with path-restricted permissions (third-party library artifact, shared across 8 unrelated developers)2 occurrences
Interpretation & review guidance
An exported content provider declares no permission. Other apps on the device may reach it — verify it enforces access control internally; this flags the attack surface, not a confirmed leak.

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

- 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.

Is this your app?
The findings above are counts. The app's developer can see each one in context, be told when a new build changes the result, and re-check any backend that answers. Verify that you control startpage.com (the site on this app's Play listing) to open that view. Free; no card.

Data collection & flow (privacy signal, not part of the grade)
- Approximate location, Precise location requested while 1 ad/attribution SDK(s) are present (Google AdMob) — location commonly feeds ad targeting.
- Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI) with 2 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
- Camera, Contacts, Microphone, Personal info, 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.

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/bd3f0a67-5cc8-43d7-98cc-15bf00b45f9f/findings.sarif (also coverage.json and proof.json).
