As developers, we understand how important your privacy is.
This app does not collect or transmit any data from your photo library. Your photos and their information never leave your device.
For photo compression, the app uses technology officially provided by Apple.
This technology does not use any servers and operates entirely on your iPhone or iPad, meaning it can be used even offline (without Wi-Fi).
It is designed with your privacy in mind.
We hope you’ll give the app a try and find it useful.
If there are features that are not currently supported, we may consider adding them if there is enough demand.
