Static checks identify review items, not a guarantee of safety.
Overview
3 finding categories to review
Vivaldi Browser - Fast & Safe (com.vivaldi.browser) scored grade A, 97 out of 100, in a static scan of version 8.2.4147.114 on 2026-09-29. It has no high or critical findings, and 3 lower-severity finding categories across 23 occurrences. No tracking SDKs were recognised in the package. 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
lowExported content provider without permission (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.
- 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.
- Evidence
- 20 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.
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.

Data collection & flow (privacy signal, not part of the grade)
- Personal-data permissions/identifiers appear on-device, but no third-party analytics/advertising SDKs were detected that would receive them.
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 not recorded.
No SDKs detected by this scan.

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/dd71e5e0-7fb4-430c-84b0-b5405e069d4d/findings.sarif (also coverage.json and proof.json).
