Overview

Limited assessment

5 finding categories to review

eCalendar - Daily Planner (com.fujia.ecalendar) was scanned at version 1.48.0 on 2026-09-29 but is not graded, because the analysis did not complete enough of its checks for a score to mean anything. The checks that did run recorded 5 finding categories across 6 occurrences; because the analysis did not complete, the absence of anything more severe is not a result. 6 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.
Open in all findingsRequest a correction
lowAlibaba Cloud OSS bucket reference1 occurrence

Interpretation & review guidance

An Alibaba Cloud OSS bucket reference. Normal to use object storage; risky only if the bucket ACL allows public read/list.

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.

lowApplication 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.

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.

  • Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI) with 4 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
  • Calendar, Camera, 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.

Data Safety comparison is not conclusive because analysis coverage is incomplete or unknown.
