Blood: Period & Cycle Tracker
PSLOVE PTE. LTD. · Build 3.14.8
Static checks identify review items, not a guarantee of safety.
Overview
4 finding categories to review
Blood: Period & Cycle Tracker (com.pslove.periodtracker) scored grade A, 96 out of 100, in a static scan of version 3.14.8 on 2026-10-10. It has no high or critical findings, and 4 lower-severity finding categories across 41 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
lowFirebase Realtime Database reference2 occurrences
Interpretation & review guidance
A Firebase Realtime Database URL. Nearly every app that uses Firebase ships one. It's only an exposure if the database rules are world-readable — that's what live verification checks.
- 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 reference4 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
- 4 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)2 occurrences
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
- 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.

Privacy signals
Capabilities and bundled software do not prove that data was collected or transmitted.
Requested permission inventory (17)
Data collection & flow (privacy signal, not part of the grade)
- Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI) 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.
Data Safety: declared vs observed (Play label vs our analysis)
We compare the developer's Google Play Data Safety declaration with what the binary can actually do (permissions it requests, identifier APIs and third-party SDKs it ships). A mismatch is a capability signal to confirm — a requested permission is not proof of collection.

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/8762287d-fe10-43e0-8a57-91b6405cf29b/findings.sarif (also coverage.json and proof.json).
