About this app

This app is a simple utility that fills your device with dummy data to reduce available storage space.

■ WHEN TO USE IT
- Before selling, giving away, or trading in your device, if you’re concerned that deleted files may still remain
- When you want to test how apps or your device behave when storage space is running low
- When you simply want to intentionally reduce the amount of available storage

■ KEY FEATURES
- Write dummy data using a specified amount of storage (fixed size, percentage, or custom amount)
- Delete the written data with one tap and see how much storage space has been freed
- Choose between Light, Dark, or System default appearance
- Save frequently used storage amounts as Quick Settings
- Switch between color themes

■ ABOUT ERASING DATA
This app fills free storage space with dummy data. However, this alone does not guarantee that previously deleted files will become completely unrecoverable.

If you need to securely erase your data, we recommend performing a factory reset on your device.

■ BUILT WITH SAFETY IN MIND
Although filling free storage may seem like a simple operation, completely filling a device can cause instability or unexpected behavior.

This app is designed to leave the minimum amount of free storage required by the system. Available storage is also checked continuously while writing to help prevent the device from being filled completely.

Written data is safely deleted in the background, and the progress can be easily monitored with a circular progress indicator.
