Privacy Policy
Lucid App Studios ("we," "our," or "us") operates the MindStream mobile application and web app (the "App"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our App.
1. Information We Collect
Information You Provide
- Account Information: When you create an account, we collect your email address, first name, and password.
- User Content: We collect the thoughts, notes, tasks, events, and ideas you create within the App ("Thoughts"), including any tags, dates, or other metadata you add.
- Voice Input: If you use the voice recording feature, your speech is processed to convert it to text. Audio is not stored after processing.
Information Collected Automatically
- Device Information: We may collect information about your mobile device, including device type, operating system, and unique device identifiers.
- Usage Data: We collect information about how you interact with the App, such as features used and time spent in the App.
2. How We Use Your Information
We use the information we collect to:
- Provide, maintain, and improve the App
- Process and organize your Thoughts using artificial intelligence
- Sync your data across devices
- Send you important updates about the App
- Respond to your inquiries and provide customer support
- Process subscription payments
3. AI Processing & Third-Party AI Services
MindStream uses Google Gemini (operated by Google LLC) to power AI features including Smart Capture, Tidy Up, Brain Search, Flow Mode, and Morning Briefing. When you use these features, the text content of your Thoughts is transmitted to Google's servers for processing.
What is sent to Google Gemini:
- The text content of Thoughts you submit for AI processing
- Voice-transcribed text (audio itself is never transmitted)
- Search queries you enter in Brain Search
What is NOT sent:
- Your email address or account credentials
- Payment or billing information
- Photo or file attachments
- Thoughts you have not explicitly submitted for AI processing
All AI requests are routed through our secure server-side infrastructure — your Thoughts are never sent directly from your device to Google. Google processes this data subject to their own Privacy Policy. We do not permit Google to use your data for training AI models under our service agreement.
By using AI features in MindStream, you consent to this processing. You may withdraw consent at any time in Settings → Data & Privacy. Withdrawing consent disables AI features but does not affect your stored Thoughts or account.
Please refer to Google's Privacy Policy for information on how Google handles data processed through their APIs.
4. Data Storage and Security
- Your data is stored securely using Supabase, a cloud database service
- We implement industry-standard security measures including encryption and secure authentication
- Your Thoughts are private and can only be accessed by you when logged into your account
- We use Row Level Security to ensure users can only access their own data
5. Data Sharing
We do not sell, trade, or rent your personal information to third parties.
We may share your information only in the following circumstances:
- Service Providers: With third-party services that help us operate the App (Supabase for data storage, Google for AI processing, RevenueCat for subscription management)
- Legal Requirements: If required by law or to protect our rights
- Business Transfers: In connection with a merger, acquisition, or sale of assets
6. Third-Party Services
The App uses the following third-party services:
- Supabase (Authentication and Database): Privacy Policy
- Google Gemini (AI Processing): Privacy Policy
- RevenueCat (Subscription Management): Privacy Policy
- Apple App Store / Google Play Store: Apple Privacy Policy / Google Privacy Policy
7. Your Rights and Choices
You have the right to:
- Access: View all data associated with your account within the App
- Export: Export your data in JSON format via the Settings menu
- Delete: Delete individual Thoughts or clear all your data via the Settings menu
- Withdraw AI Consent: Disable AI processing at any time in Settings → Data & Privacy
- Account Deletion: Request complete deletion of your account via Settings or by contacting us
8. Data Retention
- Your Thoughts are retained until you delete them
- Archived Thoughts are automatically deleted based on your auto-delete setting (7, 30, or 90 days)
- If you delete your account, all associated data will be permanently removed within 30 days
9. Children's Privacy
The App is not intended for children under 13 years of age. We do not knowingly collect personal information from children under 13. If we discover that a child under 13 has provided us with personal information, we will delete it immediately.
10. International Data Transfers
Your information may be transferred to and processed in countries other than your own. These countries may have different data protection laws. By using the App, you consent to this transfer.
11. Changes to This Privacy Policy
We may update this Privacy Policy from time to time. We will notify you of any changes by updating the "Last Updated" date at the top of this policy. We encourage you to review this Privacy Policy periodically.
