Overview

Analysis recorded

5 finding categories to review

Gizmo: AI Flashcards and Tutor (ai.saveall.app) scored grade A, 96 out of 100, in a static scan of version 3.2.93 on 2026-09-30. It has no high or critical findings, and 5 lower-severity finding categories across 9 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.

lowAmazon S3 bucket reference5 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.

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.

Open in all findingsRequest a correction
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.

lowSentry DSN1 occurrence

Interpretation & review guidance

A Sentry DSN. These are client-side by design (embedded in apps to send crash reports), so presence is expected; it only lets someone send events to the project, not read data. Low severity — included for inventory.

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.
