Old Telephone Ringtones
Ringtones and Wallpapers Apps by Trela · Build 13.5.4
Static checks identify review items, not a guarantee of safety.
Overview
1 high or critical finding category to review
Old Telephone Ringtones (com.bestringtonesapps.oldphoneringtones) scored grade F, 34 out of 100, in a static scan of version 13.5.4 on 2026-10-12. It has 1 high or critical finding among 6 finding categories across 8 occurrences. One finding was confirmed live: an anonymous request reached a backend the app references and it answered without authentication. No credential was used and no stored data was read. 13 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
criticalDigitalOcean Spaces reference — confirmed publicly readable3 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).
- Evidence
- 3 recorded occurrences in the analyzed APK. These are distinct stored findings, not a count of every source match.
- Verification
- 1 historically verified occurrence at the recorded scan time. Current reachability is not established.
mediumShort signing key (RSA 1024-bit)1 occurrence
Interpretation & review guidance
The signing key is shorter than the modern 2048-bit RSA minimum. Short keys are cryptographically weaker; a release should re-key to at least RSA-2048 (or an EC key).
- 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.
lowData Safety label omits Contacts1 occurrence
Interpretation & review guidance
The app's Google Play Data Safety label omits a data category it can actually access — a permission it requests, or an advertising/device identifier it references. Under-declaring collection is a Play policy issue and a COPPA/privacy concern. This is a static signal: a requested permission is capability, not proof of collection — confirm against runtime behavior.

lowFirebase Realtime Database reference1 occurrence
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.

lowFirebase Storage bucket reference1 occurrence
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.
- Evidence

Privacy signals
Capabilities and bundled software do not prove that data was collected or transmitted.
Contacts Storage
Requested permission inventory (24)
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 10 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
- Contacts, 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.
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/6c33f4b3-374c-4edb-ae00-5e0b30ebaa25/findings.sarif (also coverage.json and proof.json).
