Privacy policy
Minibyte processes everything on your device. This page explains precisely what that means.
The short version
Minibyte does not collect, transmit, or share anything. It has no account system, no analytics, and no advertising. Your photos never leave your iPhone.
What the app accesses
With your permission, Minibyte reads your photo library to measure file sizes, find duplicates, and re-encode the items you select. It also reads how full your device's storage is, so it can show you that number on the home screen.
Where processing happens
All analysis and compression runs on this device using Apple's own frameworks — Photos, Vision, Image I/O, and AVFoundation. No image, video, thumbnail, or fingerprint is ever uploaded. Scanning a library that uses iCloud Photos asks iOS to download the photos this device is not holding, so they can be compared like the rest; that happens inside your own iCloud account, over Wi-Fi only, and you can turn it off in Settings.
What is stored
A record of each operation (date, media type, sizes before and after) is kept on your device so you can see your history. Compressed files are written to a temporary folder and cleared automatically. Deleting the app removes all of it.
Deleting photos
Minibyte never deletes anything silently. Every deletion goes through iOS's own confirmation prompt, and deleted items stay in Recently Deleted for 30 days, where you can restore them.
Third parties
There are none. Minibyte includes no third-party SDKs and contacts no servers of its own. The only network activity it can cause is iOS fetching your own photos from your own iCloud account.
Children
Minibyte collects no personal information from anyone, including children.
