The deal, plainly
- Monthly, cancel any time; the ledger runs to the end of the paid month.
- Your records are yours. Export them at any time as CSV and as the printed ledger. On cancellation they stay exportable for the three years the rule keeps them in scope.
- A contractor's customer data is the contractor's. It is never sold or shared, and there is no marketplace.
- The product records and computes. It does not certify compliance, and no page here will say it does.
- 30-day refund on the first payment, no questions.
40 CFR 84.106(l), (l)(1) · verified 2026-09-04 · three years is the rule's retention, and the export honours it
