MoodStack – Data & Privacy Overview

Authentication

Users can currently sign in using Apple. Google login is coming soon.

Image Analysis

Images are temporarily stored for AI analysis (e.g., extracting text) and deleted after a few hours. We use external AI providers to analyze text from images and retrieve relevant data from the web.

Supplement Scanning

When scanning supplements, we use OpenFoodFacts.org to get product names and detailed content information (like ingredients).

Data Stored

• Mood logs
• Supplementation schedules
• Location & Country: We only store the country code (e.g., "FR" or "US"). We do not ask for or use exact geolocation. Some third-party services (e.g., Firebase or payment providers) may detect the country via the device or IP address, but we don’t access or use precise location data.

AI Requests Are Anonymous

Our AI systems cannot identify individual users. All requests are processed without personal identifiers.

AI Provider

We primarily use OpenAI. Some requests may be cached or stored temporarily for analytics and performance improvements.

Hosting

Our infrastructure runs on AWS and Neon.

Local Storage

Some data may be stored locally on the user’s device (async storage) to improve the user experience.

Sharing

Users can choose to share their stack. If they do, their username (if set) will appear.

Referrals

Referrals work only through referral codes (no tracking links or email invitations).

Security

Users authenticate securely via Apple. Data is not currently encrypted at rest but is stored securely within our infrastructure.

No Sensitive Info

We do not collect or store sensitive data like biometric information or exact location.
