Frequently Asked Questions (FAQ)

Can blurred data be un-blurred by someone else?

No. The Gaussian blur permanently overwrites pixel values on the image canvas before saving or copying.


Is my screenshot uploaded to any online server?

No. The utility operates 100% locally on your computer, ensuring total data privacy.
