Website. Static pages and fictional examples work without analytics, tracking cookies, data collection forms or external font requests. Hosting receives technical request data such as your IP address and browser information. The selected host’s retention practices and terms must be confirmed before launch.

Extension data. Student profiles, prepared lessons and history are stored locally in your browser. Preferences and the preparation form are also saved in Chrome. Teaching data is not automatically synced to the cloud.

AI providers. When you open and insert a prompt into Gemini, ChatGPT or Claude, its contents become available to that service before you manually send it. Review the text and remove unnecessary personal details. The provider’s own terms govern its processing.

Google sign-in. For Pro, the extension uses Google sign-in and the RKI Studio subscription server. The server receives a verified account identifier and email to check access. Student profiles and lesson materials are not needed for payment and are not sent into the payment flow.

Payments. Stripe processes payment details. The subscription server uses subscription and access information. This website does not take payments, store card details or confirm Pro from a return URL.

Backups. JSON exports contain local teaching data. You choose where to store files and whom to share them with. Keep backups secure and review their contents before sharing.

Support. Email to root@hannlabs.com sends your email address and message to the support email system. Do not send real student data, prompts containing personal information or backups. Use the same contact for data questions.
