Datenschutz Policy

Our Core Commitment

We do not store your photos. This is the foundation of our privacy promise. Every image you upload is:

• Processed entirely in the server's memory
• Used only for the duration of the analysis
• Permanently deleted immediately after the analysis results are returned

We have designed our system so that it is technically incapable of retaining your images. No copies are written to disk, no backups contain your photos, and no third-party services receive your image data. Once your analysis results are displayed, the original image buffers are garbage-collected and cannot be recovered.

Information We Collect

Information You Provide Voluntarily

If you create an account, we collect:

• Your email address (used only for account authentication and password resets)
• A hashed (one-way encrypted) password — we never store your raw password
• Fitness data you choose to enter (height, weight, age, activity level, body measurements, workout logs)

This data is stored securely and associated with your account so you can access it across devices. You may delete your account and all associated data at any time through your profile settings.

Non-Personal Information

When you use our service, the following non-personal information may be collected:

• Anonymous usage statistics (pages visited, features used, tool interactions)
• Browser type, language, and version
• Device type, screen resolution, and operating system
• Referral URL and approximate geographic region (country-level only)

This data is aggregated and used solely to improve our service and understand feature adoption. It cannot be used to identify you individually.

How We Use Your Data

We use collected information for the following purposes:

• To provide and maintain the body analysis and fitness tracking features
• To improve and personalize your experience across our tools
• To display advertisements via Google AdSense
• To detect, prevent, and address technical issues or abuse
• To communicate with you about service changes or account-related matters

We do not sell, rent, or trade your personal information to third parties for their marketing purposes.

• Essential cookies: Required for basic site functionality, including session management and security. These cannot be disabled.

Third-Party Services

We use the following third-party services in the operation of our site:

• Google AdSense — For serving advertisements. AdSense may use cookies, web beacons, and similar technologies as described in Google's Privacy Policy. AdSense collects data including your IP address, browser type, device information, and interaction with ads.
• Cloudflare — For content delivery network (CDN) services, DDoS protection, and performance optimization. Cloudflare may process your IP address and request metadata as described in Cloudflare's Privacy Policy.
• jsDelivr — For serving open-source JavaScript libraries and CDN assets. jsDelivr does not set cookies or track users. See jsDelivr Privacy Policy.

Each third party processes data according to their own privacy policies. We encourage you to review these policies for complete information.

AI Trainer and Client-Side Processing

The AI Fitness Trainer available on this site runs entirely in your web browser using WebAssembly and ONNX Runtime. When you use the AI Trainer:

• The AI model is downloaded to your browser's cache — it does not run on our servers
• All messages you type are processed locally on your device
• No conversation data, queries, or responses are transmitted to our servers
• The model file (~90 MB compressed) is served via jsDelivr CDN

This design ensures that your conversations with the AI Trainer remain completely private and never leave your device.

Data Retention

Our data retention policies are as follows:

• Uploaded images: Zero retention. Deleted immediately after analysis.
• Account data: Retained for as long as your account is active. You may delete your account at any time, which permanently removes all associated data.
• Anonymous usage statistics: Retained in aggregated form for up to 26 months, then anonymized further or deleted.
• Server logs: Standard web server logs (IP address, timestamp, request path) are retained for up to 30 days for security and troubleshooting, then automatically rotated and deleted.

Data Security

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

• Images are processed in isolated memory buffers that are garbage-collected after each request
• Passwords are hashed using bcrypt with a cost factor of 12
• All traffic is encrypted in transit using TLS 1.3
• Our servers run with minimal permissions and no persistent storage of user-uploaded content
• Database access is restricted to authorized services only
• Regular security audits and dependency updates are performed

Children's Privacy

Our services are not directed to individuals under the age of 13 (or 16 in the European Economic Area). We do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us so we can delete it.

International Data Transfers

Our servers are located in the United States and European Union. If you access our service from outside these regions, your data may be transferred to and processed in these locations. We ensure appropriate safeguards are in place for international data transfers, including Standard Contractual Clauses where required by applicable law.
