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.

Private

Your files never leave your device. Everything runs in your browser — no uploads, nothing stored.

Certain

No AI, so no hallucinations. A deterministic engine reports every real change and never invents one.

Fast

No upload, no server wait. Comparisons run locally and keep working offline once the page has loaded.
