Why Full Disk Access
macOS hides Mail, Safari and app data from every app. With Full Disk Access CoreTend can measure them; without it, it reads what macOS allows and says so.
Built to be trusted
CoreTend works on your Mac and nowhere else. It reads freely and changes nothing until you decide.
Reading is not changing
Scans read names, sizes and dates; file contents are read only to compare copies. Nothing is written into what is scanned.
Every move is yours, and reversible
You review, then CoreTend checks each item again just before moving it to the macOS Trash. Undo puts it back; nothing is ever erased.
Nothing leaves your Mac
No account, no analytics. The only request asks coretend.ahmetbsbnr.com whether an update exists, and you can turn it off. Open source, so anyone can check.
