Refund and cancellation policy

Last updated: 15 September 2026

Current calculator version

This calculator contains no payment form, checkout, paid subscription, or automatic renewal. It does not request or store card details. There is no calculator payment to refund through this interface.

External purchases

Purchases from linked websites, AI providers, app stores, or other sellers are separate transactions. Consult the seller's receipt and purchase terms. This page does not change those contracts or restrict rights provided by law.

Mandatory rights

Nothing in this policy imposes a blanket no-refund rule or waives statutory cancellation, withdrawal, defective-service, charge-dispute, or other consumer remedies. If a paid calculator offer is introduced, the seller must state the total price, cancellation process and applicable refund/withdrawal rights before taking payment. Any lawful exception for digital content or immediate performance requires the specific disclosures and consent required by the applicable jurisdiction; use of this free interface is not such consent.
