| Aspect | Findings | Recommendations |
|--------|----------|-----------------|
| Code Signing | APK signed with Robi’s production key (SHA‑256 fingerprint matches official documentation). | Verify fingerprint before side‑loading. |
| Transport Security | All API calls use TLS 1.3 with certificate pinning (Robi’s public key). | No further action required. |
| Data Storage | Sensitive tokens (access/refresh) stored in EncryptedSharedPreferences. Cache files are encrypted. | Ensure device is not rooted; encrypted storage mitigates data leakage. |
| Permissions Model | Follows Android runtime permission best practices; optional permissions are request‑on‑need. | Users should decline optional permissions if not needed. |
| Third‑Party SDKs | Includes analytics SDK (Firebase) and payment SDKs (Bkash, Nagad). | Review privacy policy for data shared with third parties. |
| Vulnerability Scan (as of Apr‑2026) | No critical CVEs detected. Minor findings: outdated org.apache.http library (fixed in v5.2). | Apply next app update (Robi has scheduled a patch for May‑2026). |
| Privacy Policy | Clearly states data usage: account info, usage stats, location (if granted), and anonymized analytics. | Users should read the policy; opt‑out of location if uncomfortable. |
