Static checks identify review items, not a guarantee of safety.

Backend checks: this build references 2 cloud backend categories that this scan did not check, so their access state is not recorded. That is not evidence they are closed.

Overview

Analysis recorded

3 finding categories to review

FemVerse AI Female Health App (com.period.tracker.women.health.nutrition) scored grade A, 97 out of 100, in a static scan of version 4.0.6 on 2026-11-06. It has no high or critical findings, and 3 lower-severity finding categories across 168 occurrences. 9 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.

lowDigitalOcean Spaces reference164 occurrences

Interpretation & review guidance

A DigitalOcean Spaces reference. Normal to use object storage; the risk is only if the space is publicly listable/readable (live-verified).

Reference: CWE-200 · CWE-284 · MASVS-STORAGE-2 — what the control asks for, and other apps with the same finding.

Evidence
164 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 reference3 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.

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.
