About 데이터 덮어쓰기
Fills empty storage space with dummy data to overwrite traces of photos and files that have already been deleted.
This is useful for developers and testers who want to clean up personal information before selling a used phone or resetting the device, or to verify that apps function properly when storage is low.
■ Key Features
· Real-time storage gauge — View usage and free space at a glance
· Fill storage as much as you want — 100MB / 1GB / 5GB / Max
· Cleanly delete filled dummy data with a single tap
· No server or login required, no personal information collected
■ For:
· Those who want to clean up data before selling or returning a used phone
· Those who want to overwrite free space before a factory reset
· Developers and QA testers for low storage (filled storage) situations
※ Important: Due to the default encryption and flash memory (wear leveling) characteristics of the latest smartphones, overwriting free space alone does not guarantee 100% non-recoverability of deleted data.
Please ensure sensitive data is processed in conjunction with a factory reset.
All generated dummy files are removed when the app is deleted.
