How does the food allergy tracker identify potential sensitivities?

The app analyzes patterns between the foods you eat and symptoms you report. It looks at foods consumed 24-72 hours before symptoms occur and calculates correlation frequencies. Foods that consistently appear before symptoms are flagged as potential triggers.

Is my food diary data private and secure?

Yes! All your data is stored locally in your browser using localStorage. Nothing is sent to any server. Your food and symptom data never leaves your device, ensuring complete privacy.

Can this app diagnose food allergies?

No, this app is a tracking tool only and cannot diagnose allergies or medical conditions. It helps you identify patterns that you can then discuss with your healthcare provider for proper medical evaluation and diagnosis.

How long should I track my food and symptoms?

For best results, track consistently for at least 2-4 weeks. This gives the app enough data to identify meaningful patterns. The longer you track, the more accurate the pattern analysis becomes.

Can I export my food diary data?

Yes! You can export all your food entries, symptom logs, and analysis data as a JSON file. This allows you to back up your data, share it with healthcare providers, or import it later.
