2. How We Use Your Data

3. Data Storage and Security

Your data is stored on secure servers provided by Supabase, our cloud infrastructure provider. All data is encrypted at rest and in transit using industry-standard encryption protocols (AES-256 and TLS 1.2+).

We implement appropriate technical and organizational security measures to protect your personal information against unauthorized access, alteration, disclosure, or destruction. However, no method of electronic storage or transmission over the Internet is 100% secure, and we cannot guarantee absolute security.

4. Third-Party Services

We use the following third-party services to operate and improve the App:

• OpenAI / AI Providers: To power AI-driven features such as workout generation and food analysis. Only the minimum necessary data is sent for processing, and we do not send personally identifiable information.

Each third-party service has its own privacy policy governing the use of your information. We encourage you to review their policies.

5. HealthKit Data Usage

StayFit integrates with Apple HealthKit to provide a more comprehensive fitness tracking experience. With your explicit permission, we may:

• Read step count, heart rate, sleep analysis, and active energy data from Apple Health.
• Write completed workout sessions (including type, duration, and calories burned) back to Apple Health.

We do not sell, share, or use HealthKit data for advertising or marketing purposes.

HealthKit data is stored only on your device and in your secure, private account. It is never shared with third parties, used for ad targeting, or included in analytics. Access to HealthKit data can be revoked at any time through your device's Settings → Health → Data Access & Devices.

6. AI Data Processing

StayFit Pro uses AI to provide personalized features. When you use AI-powered features:

• Food Photo Analysis: When you photograph a meal for macro estimation, the image is sent to our AI provider for processing. The image is not stored by the AI provider after processing is complete.
• Workout Generation: Your workout history and preferences may be used to generate personalized workout plans. Only anonymized, aggregated data is used.
• Recovery Insights: Your workout patterns and, if permitted, HealthKit data may be analyzed to provide recovery suggestions.

AI-generated estimates and suggestions are approximate and should not be treated as professional medical or nutritional advice.
