| Replay Attacks | Re‑using old OAuth tokens. | Short‑lived access tokens (15 min) with refresh token rotation; server validates iat claim. |
| Device Tampering | Running on rooted device to extract secrets. | Play Integrity API + SafetyNet attestation; app disables private collections on compromised devices. |
| Unauthorized Media Access | Exporting cached images from /data/data/.../cache. | Cache files stored in Context.MODE_PRIVATE; encrypted at rest using per‑file keys derived from the user’s passphrase. |
