Last Updated: October 13, 2025
Welcome to AllerGen ("we," "our," or "us"). We are committed to protecting your personal information and your right to privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile application and services.
Please read this privacy policy carefully. If you do not agree with the terms of this privacy policy, please do not access the application.
AllerGen collects and processes the following information to provide you with personalized health insights:
Important: No account creation is required to use AllerGen. All your health data stays on your device.
Your facial data privacy is our top priority. Here's exactly how we handle your face photos:
Face photos and extracted facial landmarks used to analyze inflammation markers (periorbital bags, redness, jawline sharpness, etc.)
To analyze facial inflammation and correlate changes with your food intake, helping you identify foods that may be affecting your health.
100% on-device processing using Apple Vision framework. All facial analysis happens locally on your iPhone or iPad. Your face photos never leave your device.
Locally on your device only. Face photos and facial analysis data are stored in your device's secure local storage.
Only you. Your facial data is never shared with AllerGen servers, third parties, or any external services. We cannot access your face photos.
Facial data remains on your device until you delete the app or use the "Reset All Data" option in Settings.
AllerGen uses minimal third-party services to provide our food identification feature:
No other third-party services have access to any of your data. We do not use analytics trackers, advertising networks, or data brokers.
You have complete control over your data in AllerGen:
You can export all your health data, food logs, and inflammation history at any time through the Settings menu. Your data will be provided in a standard format that you can view, save, or transfer.
Use the "Reset All Data" option in Settings to permanently delete all your facial photos, food logs, and health tracking data from your device. This action cannot be undone.
AllerGen does not require you to create an account, sign in, or provide any personal information like your name, email, or phone number. You can use the app completely anonymously.
Since all your data is stored locally on your device, you maintain full ownership and control. You can back up your data through your device's standard backup mechanisms (iCloud, local backups).
We implement strong security measures to protect your information:
Since AllerGen stores all data locally on your device:
We may update this privacy policy from time to time. We will notify you of any material changes by posting the new privacy policy in the app and updating the "Last Updated" date. Your continued use of our services after changes constitutes acceptance of the updated policy.
