Your plans. Your choice.

Your answers stay in your browser and are not sent to Eftsona or an AI service. They live only in the current tab unless you choose Save my plan on this device. That option uses local browser storage until you clear it. Anyone with access to that browser may be able to read it. Export your planning record to move it between devices.

Checkout sends the guide SKU, delivery email, billing country and policy acceptance to the Eftsona Store API. Stripe handles payment. Purchase records support access, delivery, accounting and support. Keep private purchase links secure. The app requires internet; downloaded guides work offline. Avoid storing sensitive documents, account numbers, medical records or other people’s confidential information in the app.
