Lettie ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use our mobile application.
All data processing occurs locally on your device. Your recommendation packets, user data, and API keys are stored securely on your device. We do not transmit your personal data or recommendation packets to our servers. All packet generation and processing is performed using the API keys you provide, and we do not have access to your data or API keys.
Lettie uses third-party AI services (such as Google Gemini or other AI providers) through API keys that you provide. When you use these services, your data is sent to these third-party providers according to their privacy policies. We recommend reviewing the privacy policies of any AI service providers you choose to use.
We may use third-party services for analytics and app functionality. These services have their own privacy policies.
You have the right to access, modify, or delete your personal information. You can do this through the app settings or by contacting us. Since all data is stored locally on your device, you can delete the app at any time to remove all your data.
Lettie is not intended for children under the age of 13. We do not knowingly collect personal information from children under 13.
We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last Updated" date.
