Overview

Analysis recorded

5 finding categories to review

Email Blue Mail - Calendar (me.bluemail.mail) scored grade A, 90 out of 100, in a static scan of version 2.2.408 on 2026-10-12. It has no high or critical findings, and 5 lower-severity finding categories across 17 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.

mediumCleartext (HTTP) traffic permitted1 occurrence

Interpretation & review guidance

The manifest permits cleartext (HTTP) traffic. Data sent over plain HTTP can be read or tampered with on the network; modern apps should require HTTPS.

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.

lowAmazon S3 bucket reference12 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

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.

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.

  • Camera, Contacts, Microphone, 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.
