Overview

This Privacy Policy explains how LinguaAI handles your information. Because the app uses a BYOK model, there is very little access to your data. This policy describes what is and isn't collected, how your data flows, and your rights.

What LinguaAI Doesn't Collect

Thanks to the BYOK architecture, LinguaAI does not collect, store, or have access to:

• Your Conversations: All interactions go directly from your device to the AI provider. LinguaAI never accesses your prompts or responses.
• Your API Keys: Keys are stored securely in your device's keychain and never transmitted externally.
• Personal Data: No names, email addresses, phone numbers, or other personally identifiable information.
• Usage Analytics: No tracking of how you use the app, what models you use, or what prompts you create.
• Device Information: No collection of device, operating system, or location data.

What May Be Collected

Crash Reports (Optional)

If you opt in, crash reports may be sent to help identify bugs. These contain technical information about the crash but not your conversations, API keys, or personal data. Disable crash reporting in app settings.

App Purchase Information

When you purchase through the App Store, Apple processes your payment. A transaction receipt is received from Apple but payment details remain with Apple. Apple's privacy policy governs this transaction.

How Your Data Flows

Direct Connection to AI Providers

When you send a prompt:

1. Your device retrieves your API key from the secure keychain
2. Your prompt is sent directly to the AI provider's servers
3. The provider processes your request and responds to your device
4. At no point does your data pass through LinguaAI's servers

iCloud Sync (Optional)

If you enable iCloud sync, the following is stored in your personal iCloud account:

• Your saved prompts and prompt library
• Your personal styles and preferences
• App settings and configurations

This data is encrypted and stored in your iCloud account only. LinguaAI cannot access your iCloud data. Apple's iCloud privacy policy applies.

Third-Party AI Providers

When using LinguaAI, you directly interact with third-party AI providers. Each has its own privacy policy:

• Anthropic: anthropic.com/privacy
• OpenAI: openai.com/privacy
• Google: policies.google.com/privacy
• Mistral AI: mistral.ai/privacy

Reviewing each provider's privacy policy is recommended.

Data Security

• Keychain Storage: API keys use hardware-level encryption in your device's secure keychain
• No Data Transmission: Since data isn't collected, there's no risk of interception on external servers
• Direct HTTPS: All communication uses encrypted HTTPS connections

Children's Privacy

LinguaAI is not directed at children under 13. The app does not knowingly collect information from children. Contact [email protected] if you believe your child has provided information.

Your Rights

Because LinguaAI doesn't collect personal data, there's no data to provide, correct, or delete. However, you have complete control:

• API Keys: Add, change, or remove at any time in settings
• iCloud Data: Disable sync and delete data from your iCloud account
• App Data: Delete the app and all its data at any time

Changes to This Policy

This policy may be updated from time to time. Changes will be reflected in the "Last Updated" date. Continued use after changes constitutes acceptance.

International Users

LinguaAI is available worldwide. Since data goes directly to AI providers, processing location depends on your chosen provider and their data centers.
