Frequently Asked Questions
Will CleanWarden overwrite my damaged file?No. Diagnosis is read-only and does not modify the original.
What can I do for free?Diagnosis identifies the file structure, repairability, and visible limitations before you choose a recovery path.
Can every file be repaired?No. If required content is missing or overwritten, diagnosis can explain the issue but cannot invent lost data.
Do files leave my Mac?No. Diagnosis and repair attempts are designed to run locally unless you choose to send diagnostics to support.
