Overview

Analysis recorded

4 finding categories to review

ScrollToStudy: AI Study Tutor (com.marcstudio.scrolltostudy) scored grade A, 97 out of 100, in a static scan of version 3.4.3 on 2026-10-12. It has no high or critical findings, and 4 lower-severity finding categories across 4 occurrences. 3 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

lowExported content provider without permission (third-party library artifact, shared across 94 unrelated developers)1 occurrence

Interpretation & review guidance

An exported content provider declares no permission. Other apps on the device may reach it — verify it enforces access control internally; this flags the attack surface, not a confirmed leak.

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
lowSupabase anon key (public client key)1 occurrence

Interpretation & review guidance

A Supabase anon (public) key. This key is meant to ship in clients, so its presence is expected — it is only an exposure if your tables' Row-Level Security is off, which is exactly what our live check tests. Marked low unless verified.

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
lowSupabase project reference1 occurrence

Interpretation & review guidance

A Supabase project URL. Normal for apps built on Supabase — it's only an exposure if Row-Level Security is disabled and the anon key allows reading data. Verify RLS is enabled on your tables.

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.

Data collection & flow (privacy signal, not part of the grade)

StorageStorage (write)
Persistent identifiers (referenced in code)
Advertising ID (AAID)Android IDDevice ID / IMEI
Where it can go
Third parties present (2)
Google AdMobAppsFlyer
  • Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI) with 2 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
  • 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: declared vs observed (Play label vs our analysis)

We observe the app can access
no sensitive access observed
✓ No obvious mismatch between the declaration and what we observe.

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.
