Data

How SafeDiff handles your catalogue.

• Uploaded CSV files are processed locally in your browser and are not uploaded to SafeDiff servers.
• Analysis is deterministic — no AI services or third-party APIs receive your data.
• License activation sends your email, license key and your acceptance of the Terms and Disclaimer to SafeDiff’s server, which verifies the key with Lemon Squeezy. The app also checks your license cookie with our server when the workspace loads.
