Your learning. Your choice.

Your practice responses and self-reported progress stay in your browser. They are not sent to Eftsona or an AI service. By default they live only in the current tab. If you choose Save my practice on this device, they are saved in that browser’s local storage until you clear them. Anyone with access to that browser may be able to read them. Export your record to move it to another device.

Checkout sends the course SKU, delivery email, billing country and policy acceptance to the Eftsona Store API. Stripe handles payment information. Purchase records support access, delivery, accounting and support. Your private purchase links grant course access; keep them secure. Course pages and purchase responses are not cached for offline access.

Do not put sensitive records or other people’s confidential details in exercises. Contact support@eftsona.com for privacy or order questions.
