Privacy
This policy applies to the EaseGut (肠自在) Android and iOS apps and related services. EaseGut is operated by 有一点点小科技（仙游）有限公司. We collect and use information only as needed to provide the service, never sell personal information, and do not use it for unrelated advertising profiles.
1. Information we collect
Account information (email or phone number, display name, account status, verification and login security records); device and security information (Android ANDROID_ID or Apple IDFV, IP address, device model, OS and app version, and necessary request logs for security and troubleshooting); records you enter about meals, symptoms, bowel movements, IBS phase and preferences; AI inputs such as food queries, recipe requests, selected images, recognized ingredients and phase preferences; Health Connect or HealthKit data only after you grant permission; and purchase receipts, subscription status, invitations, support feedback and push-notification tokens.
2. How and why we collect it
Information is collected through sign-up and sign-in forms, actions you take in the app, system authorization APIs and necessary network requests. We use it to provide login, food and symptom-management features, AI assistance, subscription validation, anti-fraud protection, service notifications and product reliability improvements. We do not access photos, camera data or Health Connect/HealthKit data without your action or permission. Meal, symptom, bowel and health records remain on the device by default on Android and are not automatically uploaded as journal records.
3. AI and third-party processing
AI requests are sent through our server to the configured model provider. We send only what is needed for the requested feature: food text, recipe needs, phase or preference context, recognized ingredients, or an image you chose to analyze. We do not intentionally attach your name, email, phone number or password to these requests. Some food-query responses may be cached on our server for review, quality control and abuse prevention. We do not sell personal information or use health records for advertising.
4. Storage, retention and deletion
Local meal, symptom, bowel and health data is stored on your device. You can delete records or request account deletion in the app. Account, subscription, support and security-audit records are kept only as long as needed to provide the service, resolve disputes or meet legal obligations, then deleted or anonymized. AI request caches and operational logs are retained only for review, quality, security and billing needs and are cleaned up by the administrator as required.
5. Security measures
We use HTTPS/TLS for data in transit; scrypt salted one-way password hashing; authenticated sessions and Bearer Tokens for sensitive APIs; account-level access controls; server-only storage of model API keys; rate limits, input validation and error handling for login, verification and AI APIs; necessary audit logs; release-code shrinking and resource protection; and ongoing dependency and security maintenance. If a security incident occurs, we will take remedial action and notify users and authorities as required by law.
6. Your rights and contact
You may request access, correction, deletion or withdrawal of consent, including notification and Health Connect/HealthKit permissions. Use the settings page or email legal@easegut.life. We verify the request before processing it; records that must be kept by law will be deleted or anonymized when the retention period ends.
