Privacy Policy

MealSight (餐识) · Last updated: 20 October 2026

MealSight ("the app", "we", "us") is a meal-photo nutrition app. This policy explains what data the app handles and how. We designed the app to collect as little as possible. There are no user accounts, and we do not ask for your name, email, or contact information.

1. Information the app handles

• Meal photos. When you take or choose a photo to analyze, the image is sent to our processing backend and on to a third-party AI provider to identify the food and estimate nutrition. The image is used only to produce your result. If the analysis is queued, that photo is kept only until the analysis finishes or fails, then deleted, and is not used for anything else.
• A random device identifier. The app generates a random per-installation identifier and a device-attestation key used solely to prevent abuse and apply fair-use rate limits to the analysis service. For the same purpose our backend keeps daily request counts keyed by this identifier and by your IP address; these counts are deleted the following day. They are not linked to your identity and are not used for advertising or tracking.
• Health data (optional). If you grant permission, the app writes the nutrition of meals you save (energy and macronutrients) to Apple Health. The app does not read any data from Apple Health. This data stays on your device within Apple Health and is not transmitted to us.
• Subscription status. If you subscribe, the purchase is processed by Apple through the App Store. We receive only whether an entitlement is active — we never receive your payment details.
• Your meal history. Saved meals, their photos, and analysis results are stored locally on your device. They are not uploaded to our servers.
• App Clip. The App Clip opened from plateprint.w-skill.com/clip can analyze one meal photo before you install the full app. It follows the same rules: the photo is sent only to produce that result, and a random device identifier plus your IP address are used for a separate, tighter daily limit that does not change the limits for the full app. We count App Clip analyses and landing-page visits per day and do not store personal data with those counts. Meals analyzed in the App Clip stay on your device and are imported into MealSight's diary after you install the full app. The App Clip does not read or write Apple Health and does not offer subscriptions.

2. How we use it

Solely to provide the app's features: recognizing food from your photo, estimating nutrition, letting you record meals, optionally syncing nutrition to Apple Health, preventing abuse of the analysis service, and managing your subscription entitlement. The App Clip uses the same analysis path and the same limits on what we keep. We do not use your data for advertising or profiling.

3. Third parties

• Third-party AI provider. Receives the meal image and any note to perform the analysis, under its own privacy terms.
• Cloudflare. Hosts the backend that relays analysis requests.
• Apple. Provides In-App Purchase (subscriptions) and HealthKit.

We do not use third-party analytics or advertising SDKs, and we do not sell your data.

4. Data retention

A queued photo is kept only until the analysis finishes or fails, then deleted, and is not used for anything else. Your meal history still stays on your device until you delete it in the app or uninstall the app. Health data is retained by Apple Health under your control.

5. Your choices

• Delete individual meals in the app, or remove all app data by uninstalling.
• Manage or revoke Health permissions in the iOS Health app or Settings.
• Manage or cancel your subscription in your Apple account settings.

6. Children

The app is not directed to children under 13 and does not knowingly collect personal information from them.

7. Security

Requests are transmitted over encrypted connections (HTTPS). The analysis service uses device attestation to help ensure requests come from the genuine app.

8. Changes

We may update this policy; material changes will be reflected on this page with a new "last updated" date.
