Overview

Analysis recorded

4 finding categories to review

Habit Tracker - HabitKit (com.roehl.habitkit) scored grade A, 96 out of 100, in a static scan of version 1.17.3 on 2026-10-10. It has no high or critical findings, and 4 lower-severity finding categories across 9 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.

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.

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
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
1 recorded occurrence in the analyzed APK. These are distinct stored findings, not a count of every source match.

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.

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

Data the app can access
No sensitive runtime permissions requested.

Advertising ID (AAID)Android IDDevice ID / IMEI
Where it can go
Third parties present (2)
Google AdMobGoogle Firebase Analytics
  • 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.

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.
