3. How We Use Your Information
We use the collected information for the following purposes:
To provide and improve the educational features of the App (including personalized local civics questions)

4. Voice and Speech Data
When you use the voice features (speaking answers to Noah), your voice is processed in real time for speech recognition. We do not permanently store your voice recordings unless necessary for technical improvement, and in that case the data is anonymized.

We use the following third-party services:
Google Play Billing – for subscription management

These services have their own privacy policies. We only share the minimum data necessary for the App to function.

Practice progress and review data are stored until you delete your data or uninstall the App.
Voice data is processed temporarily and not retained longer than necessary.
You can request deletion of your data at any time by contacting us.
7. Data Security
We implement reasonable technical and organizational measures to protect your information. However, no method of transmission over the internet is 100% secure.
