RV AppStudios · Build 2.5.2
Static checks identify review items, not a guarantee of safety.
Overview
2 finding categories to review
ABC Kids - Tracing & Phonics (com.rvappstudios.abc_kids_toddler_tracing_phonics) scored grade A, 99 out of 100, in a static scan of version 2.5.2 on 2026-10-12. It has no high or critical findings, and 2 lower-severity finding categories across 3 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
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.
infoApplication data is backup-enabled1 occurrence
Interpretation & review guidance
The app allows Android backups (android:allowBackup="true"). App data can then be extracted via adb backup on many devices — a concern if the app stores tokens or personal/health/payment data locally. Common and low-severity, but worth disabling for sensitive apps.
- Evidence
- 1 recorded occurrence in the analyzed APK. These are distinct stored findings, not a count of every source match.

Privacy signals
Capabilities and bundled software do not prove that data was collected or transmitted.
Requested permission inventory (9)
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.
Build & components

Embed the latest grade
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/327073dd-b512-4fac-8b26-104ee55a2826/findings.sarif (also coverage.json and proof.json).
