4.1 Third-Party AI Services - Data Sharing Disclosure

IMPORTANT: Our app sends your personal data to third-party AI service providers to enable its core AI chat functionality. Before any data is shared, the app will present you with an explicit consent dialog that describes the data sharing practices below. You must accept this consent before any data is transmitted to AI providers. You may decline, but this will limit the app's AI functionality.

4.1.1 What Data We Send to AI Services

When you interact with our AI chat interface, the following specific data is transmitted to third-party AI providers via their APIs:

• Chat messages: The text content of messages you type and send in the chat interface
• Conversation history: Prior messages in the current conversation thread, used to maintain context for coherent AI responses
• File uploads: Documents and files you attach to conversations (e.g., PDFs, text files, spreadsheets) — only sent when you explicitly attach them to a message
• Images: Photos or images you share for analysis — only sent when you explicitly attach them to a message
• Function execution context: When the AI calls functions on your behalf, function names, parameters, and results are included in the conversation context sent to the AI provider

Data NOT sent to AI providers: Your email address, account credentials, payment information, IP address, device identifiers, API keys, and any data stored in your secure lockbox are never transmitted to AI service providers.

4.1.2 Who Receives Your Data — AI Service Providers

Your data is sent to one or more of the following third-party AI providers, depending on which AI model you select in the app. You can change your AI provider preference at any time in your account settings.

Data is sent to AI providers only in the following circumstances:

Data is transmitted in real time as you interact with the app. No data is sent to AI providers when you are not actively using the AI chat features.

• Revoke consent: You can revoke your AI data sharing consent at any time through your account settings. Revoking consent will disable AI chat functionality but will not affect other app features.
