Warning: Why You Should Avoid Free Play Store Resizer Apps
A search on the Google Play Store for “photo resizer 20kb” returns hundreds of free apps. However, independent security audits reveal severe issues with these tools:
- • Invasive Permissions: Many request full read access to your device contacts, call logs, and location.
- • Cloud Upload Risk: Several popular apps send your identity photos to third-party offshore cloud servers to compress them, exposing sensitive candidate data.
- • Aggressive Monetization: Full-screen unskippable video ads and deceptive “Start Trial” subscription traps.
