Privacy Policy

1. Introduction

Fitness0 is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and protect your information when you use our AI-powered fitness coaching application.

Privacy-First Approach: We use a local storage approach, meaning your personal fitness data and chat history are stored directly on your device, not on our servers. This gives you complete control over your personal information.

We are committed to compliance with the General Data Protection Regulation (GDPR) and other applicable privacy laws. This policy describes your rights and how we handle any data we process.

2. Information We Collect

2.1 Personal Information

We collect the following types of personal information:

• Profile Information: Age, gender, fitness goals, fitness level, weight, height, workouts per week, and dietary preferences
• Workout Data: Workout plans generated by our AI and workout history
• AI Chat Data: Messages exchanged with our AI fitness coach

Note: We do not currently collect email addresses, account credentials, or require user registration. All data is stored locally in your browser and can be cleared at any time.

2.2 Technical Information

We automatically collect certain technical information:

• Usage Analytics: Through Vercel Analytics (GDPR compliant), we collect anonymized data about how you interact with our application
• Performance Data: Through Vercel Speed Insights (GDPR compliant), we collect performance metrics to improve our service
• Rate Limiting Data: IP addresses for rate limiting purposes to ensure fair usage

Privacy-First Analytics: Vercel Analytics and Speed Insights are GDPR compliant and do not use cookies or collect personally identifiable information. They only collect anonymized, aggregated usage and performance data.

• Service Provision: To provide personalized AI fitness coaching, workout plans, and nutrition guidance

4.2 AI Services

We use Groq API for AI inference to power our fitness coaching features. Data sent to Groq is processed according to their privacy policy and data processing agreements that ensure appropriate protection of your personal data.

4.3 Rate Limiting & Caching

We use Upstash Redis for rate limiting and caching to ensure fair usage and improve performance. This service only processes technical data necessary for these functions and does not store personal content.

5. Data Storage and Security

We implement appropriate technical and organizational measures to protect your data:

• Local Storage: Your profile and chat data are stored locally in your browser's secure storage
• Encryption: All data transmission is encrypted using HTTPS/TLS
• Data Minimization: We collect only the data necessary for our fitness coaching services
• No Server Storage: We do not store your personal profile or chat data on our servers
• User Control: You can clear all your data at any time by clearing your browser storage

Local Storage Notice: Since your data is stored locally in your browser, clearing your browser data or using a different device will remove your profile and chat history.

6. Your Rights Under GDPR

Since your data is stored locally on your device, you have enhanced control over your information:

• Right of Access: You can view all your data directly in the application
• Right to Rectification: You can edit your profile information at any time
• Right to Erasure: You can clear all data by clearing your browser storage
• Right to Data Portability: Your data is already in a portable format in your browser
• Complete Control: Since data is stored locally, you have full control without needing to contact us

7. Data Retention

Since we use local storage, data retention is controlled by you:

• Profile Data: Stored locally in your browser until you clear it or uninstall the browser
• Chat History: Stored locally and persists until you clear your browser data
• Workout Plans: Stored locally for your convenience and historical reference
• Analytics Data: Anonymized usage data is retained by Vercel for service improvement
• Rate Limiting Data: IP addresses are temporarily stored for rate limiting and automatically expire

Your Control: You have complete control over your data retention. You can clear all stored data at any time through your browser settings or by using our app's clear data feature (if available).

8. Children's Privacy

Our service is intended for users aged 16 and above. Our onboarding form has a minimum age requirement of 16 years. We do not knowingly collect personal information from children under 16. Since we use local storage only, any data entered by underage users remains on their device only.

We may update this privacy policy from time to time to reflect changes in our practices or applicable laws. We will notify you of any material changes by:

• Posting the updated policy on our website

Your continued use of our services after the effective date of the updated privacy policy constitutes acceptance of the changes.
