Square Invoices: Invoice Maker
Block, Inc. · Build 7.28
Static checks identify review items, not a guarantee of safety.
Overview
1 finding categories to review
Square Invoices: Invoice Maker (com.squareup.invoicesapp) scored grade A, 94 out of 100, in a static scan of version 7.28 on 2026-10-09. It has no high or critical findings, and 1 lower-severity finding category across 1 occurrence. 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.
Start with these findings
mediumShort signing key (RSA 1024-bit)1 occurrence
Interpretation & review guidance
The signing key is shorter than the modern 2048-bit RSA minimum. Short keys are cryptographically weaker; a release should re-key to at least RSA-2048 (or an EC key).
- 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.

Data collection & flow (privacy signal, not part of the grade)
- Approximate location, Precise location requested while 2 ad/attribution SDK(s) are present (Google AdMob, AppsFlyer) — location commonly feeds ad targeting.
- Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI +2 more) with 4 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
- Camera, Contacts, Microphone, Personal info, Phone, 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.

The badge reads the latest recorded grade each time it is loaded, and links back to the full report so a reader can see the build it covers and what the scan could not see.
Grades can move when a new version is scanned or when a detector is corrected. If you would rather publish a grade that cannot change under you, link a signed Proof Capsule instead.
API users can request authenticated, scan-specific exports at /v1/scans/2886d655-bc55-418f-a93f-efe868529d92/findings.sarif (also coverage.json and proof.json).
