Your files stay on your Mac.

Comparing files

Input CSV and workbook files are imported and compared on your Mac. They are not sent to this website, Stripe, Cloudflare or a remote AI service.

Visiting this website

Cloudflare hosts this site and may process request information such as IP addresses and browser details. Our comparison example uses synthetic data. Cloudflare may provide request and traffic measurements. The site does not accept spreadsheet uploads.

Purchases and licenses

When purchasing is enabled, Stripe processes your payment details, email and billing information. Our Cloudflare-hosted license service stores your purchase reference, email, amount, currency and signed license to deliver the license and handle purchase support. Card numbers are handled by Stripe, not stored in our license database.

The checkout page loads Stripe when you continue to payment. Read Stripe’s privacy policy and Cloudflare’s privacy policy for their processing.

License emails

When license email delivery is enabled, Resend processes the purchase email address and license message to send your copy. It does not receive your spreadsheet files. See Resend’s privacy policy.

Offline activation

The app stores trial progress and your license on your Mac. License verification takes place locally. Keep the signed license private: anyone with it may be able to activate the app.
