Perpetual use of the purchased major version

Bug and security fixes within that major version are included. Future major upgrades may be paid and optional. CSVProof does not invent cloud features to justify recurring billing.

Your files stay local

Core editing, comparison and replay do not require uploading source data or maintaining an account.

The full workflow is the product

Parser contract, compare, review, recipes and evidence belong together, not as a maze of add-ons.
