Are my files private when I use this tool?
Yes. All comparison runs locally in your browser. Your files never leave your device and are never sent to any server — not a policy promise, but an architectural fact. There is no server receiving your data.
No AI means no hallucinations
Compare Files uses a deterministic, logic-based engine — not a language model. It reports every change that is actually in your files, and never invents one.
