Privacy Policy

Privacy Policy Last updated: October 18, 2026

Introduction Trust My Gut (“we,” “our,” or “us”) is committed to protecting your personal information. This Privacy Policy explains how we collect, use, and safeguard your data when you use the Trust My Gut app.

Information We Collect

Personal information: First name, last name, and date of birth

Account information: Email address and password

Health & nutrition data: Meals logged, gut scores, mood check-ins, daily goals, manual vitals (sleep, activity, stress, energy)

Apple Health data (with your consent): Sleep, heart rate, workouts, stand hours, active energy, and heart rate variability (HRV) — read from any wearable or app you have connected to Apple Health, such as Apple Watch, Oura Ring, Garmin, Fitbit, and Strava

Quiz data: Health goals, conditions, allergies, dietary preferences, lifestyle information, coaching style preference

Account and device identifiers: User ID and notification token, used for account functionality, syncing, and notifications you enable. Subscription information: Purchase history and billing status, used to manage access and subscription reporting.

Apple Health Integration

Trust My Gut integrates with Apple HealthKit on iOS to read health metrics from any wearable or app you have connected to Apple Health. This includes Apple Watch, Oura Ring, Garmin, Fitbit, Strava, and similar services.

What we read:

  • Sleep duration
  • Heart rate (live and resting)
  • Workouts (type, duration, calories)
  • Stand hours
  • Active energy
  • Heart rate variability (HRV)

What we do NOT do:

  • We do not write any data back to Apple Health
  • We do not modify or delete records in Apple Health. Relevant summaries may be processed as described below when you enable connected features.
  • We do not access location, medical records, reproductive health, or other sensitive Health categories
  • We do not transmit your Apple Health data to advertisers or data brokers

Your control:

  • You grant permission via Apple’s standard HealthKit permission prompt during onboarding
  • You can disable Apple Health integration anytime in Profile, which immediately stops the app from reading any Apple Health data
  • You can revoke individual permissions in iPhone Settings → Health → Data Access & Devices → Trust My Gut
  • Declining Apple Health access does not affect any other app features — you can log all vitals manually instead

How your Apple Health data is used:

  • Personalize Fiyah’s coaching responses based on how your body is doing
  • Tailor meal recommendations to your current sleep, activity, and recovery state
  • Power your daily home greeting and check-in notifications with relevant context
  • Display your daily vitals on the home screen

Android Health Connect and workout meal ideas

With your permission, Trust My Gut reads authorized steps, sleep, resting heart rate, active calories and completed exercise sessions from Android Health Connect. Exercise summaries can include workout type, end time, duration and available energy burned. Access is read-only; we do not modify your Health Connect records.

If you enable Workout meal ideas and grant background health access, the app can check for recent completed workouts while it is in the background. It uses a short-lived on-device workout summary to acknowledge recent activity and offer meal ideas. Workout-specific alerts and suggestions expire two hours after the recorded workout end time. You can disable this feature in Profile and revoke permissions in Android’s Health Connect settings. Opting out stops these checks and clears this feature’s local workout state.

When you tap for meal ideas and separately agree to AI data sharing, the necessary workout summary and relevant plan, diet and time-of-day context are sent through our backend to OpenAI to generate recommendations. Workout and other health data are not sent to advertising services. Advertising consent does not control access to workout features.

Location Information

Trust My Gut requests permission to access your device’s location, which may be precise depending on your permissions and device, when you use Restaurant search or enable location access for the Home card’s local weather. Location is used while the app is in the foreground. We use this information to:

  • Verify the existence of restaurants you search for via Google Places
  • Return relevant nearby restaurant matches based on your current area
  • Provide accurate gut-friendly ordering guidance for the restaurant you selected

What we collect:

  • Your device’s latitude and longitude, which may be precise, when you use Restaurant search. For Home weather, coordinates are rounded on your device before being sent through our backend to Google’s Weather API

What we do NOT do:

  • We do not track location in the background. With location permission, Home weather may refresh periodically while the app is open
  • We do not store your precise location history
  • We do not send device-location coordinates to advertisers or use them for advertising. Our backend and Google Places and Weather APIs process location to provide the restaurant and weather features. Approximate location inferred by advertising services from network information, when you permit measurement, is described separately below
  • We do not link your location data to your identity for marketing or profiling purposes

Caching: Coordinates may be cached on your device for up to 10 minutes to avoid repeated location requests. Restaurant queries and coordinates, and rounded weather coordinates, are sent through our authenticated backend to Google for the requested features. We do not store a precise-location history. Weather reports are cached briefly on your device; our backend keeps request-limit records without saving weather-coordinate history.

Your control:

  • You may decline location access at any time through your device’s Settings → Trust My Gut → Location
  • Declining location affects nearby Restaurant search and local weather. The Home artwork can use time-of-day scenes instead; account access and other features remain available
  • You can revoke location permission at any time without affecting your account or other data

Third-party data sharing for location:

  • When you search for a restaurant, your search query and optional location are sent through our backend to Google’s Places API to return verified matches. Local weather sends rounded coordinates through our backend to Google’s Weather API
  • Google’s use of this data is governed by Google’s Privacy Policy (https://policies.google.com/privacy)
  • We temporarily cache coordinates on your device for up to ten minutes. Restaurant search results are cached locally; saved restaurant information may sync with your account.

Product and beverage lookup

When you choose Find brand/product or scan a product barcode, the app sends your search text or barcode to Open Food Facts and the NIH Dietary Supplement Label Database to retrieve matching product labels. These services also receive standard connection information, such as your IP address. We do not include your account identifiers, saved meal or beverage history, health records, chat history or photos in these catalog requests. Please enter only product information in the search box.

Catalog results are briefly cached in the app. If you choose to analyze a product or label photo, AI processing follows the separate consent and data-sharing controls described below. The beverage and nutrition details you choose to log are saved with your account. Product formulas and label records can differ, so check the product, flavor and serving against your package. These catalogs do not endorse products or guarantee their health effects.

These independent catalog services process requests under their own policies: Open Food Facts privacy policy and NIH website policies and notices.

How We Use Your Information

  • To personalize your nutrition recommendations and gut health insights
  • To power Fiyah, your AI wellness guide
  • To calculate your Soul Score and Gut Score
  • To send relevant push notifications about your health journey
  • To adapt meal recommendations and coaching to your daily Apple Health vitals (if you have granted consent)

AI Features & Third-Party AI Processing

Fiyah and our AI-powered features use OpenAI. With your AI data-sharing consent, relevant information is sent through our secure backend to OpenAI to generate personalized responses, recipes, meal analysis, and wellness guidance.

Information shared may include your messages and relevant conversation history; meal descriptions and photos you submit; your first name, age in years, country, and relevant onboarding answers; dietary preferences, allergies, health goals and conditions you choose to share; and relevant wellness or health-metric summaries when you enable those features.

We do not intentionally include your account password or payment-card information in AI requests. Content you put in a message or photo is submitted for processing, so avoid including information you do not want processed by AI.

Your consent is required. You may decline AI sharing during onboarding or disable it in Profile settings. Disabling consent stops future AI requests; it does not retroactively remove previously processed information or your saved chat history.

OpenAI does not use API data to train its models by default. Our requests disable stored response history. This does not mean zero retention: OpenAI’s standard abuse-monitoring logs may retain content for up to 30 days, with exceptions where longer retention is required by law or necessary for safety. See OpenAI’s data controls for details.

Data is transmitted over encrypted connections.

Optional advertising measurement

With your permission through Apple’s App Tracking Transparency prompt, Trust My Gut uses Meta’s iOS SDK and RevenueCat’s Meta integration to measure which advertisements lead to app installs, app activity, trial starts, and subscriptions. This helps us evaluate our advertising.

For this purpose, Meta may receive device and advertising identifiers, a Meta-generated app identifier, app activation information, and subscription events such as a trial start, subscription purchase or renewal, along with event time, product, currency, and revenue information. Technical information such as app version, device information, and network information may accompany these events. Meta’s SDK may also collect technical usage information for analytics and crash diagnostics for SDK reliability. RevenueCat processes subscription information and sends eligible conversion events to Meta.

We do not include your meals, symptoms, gut scores, health conditions, Apple Health or Health Connect records, chat messages, photos, name, email address, or precise location in these advertising events.

You can decline tracking and continue to use the app. You can change this permission in iPhone Settings → Privacy & Security → Tracking. Our Meta integration is configured not to forward subscription events when Apple tracking permission is not authorized. Changing your permission stops future consent-dependent tracking; it does not automatically delete information already processed.

Meta processes information under Meta’s privacy policy. For questions or deletion requests, contact info@trustmygutapp.com.

Android advertising measurement

In Android versions that offer Advertising measurement, it is optional and remains off until a signed-in user chooses “I’m 18+ and allow.” If you allow it, Meta’s Android SDK measures app installs and app opens. Meta may receive the advertising identifier when Android permits it, a Meta-generated app identifier, event time, and technical device and network information, including IP address and approximate location inferred from it. We do not send precise device-location coordinates for advertising.

RevenueCat manages subscription purchases and supplies eligible trial, subscription, renewal and one-time purchase events. These events pass through our backend consent check before being sent to Meta. Permitted fields are a Meta-generated identifier, a hashed account identifier, subscription product identifier, event time, currency, revenue and basic app information. The Android app passes its permitted Meta-generated identifier to RevenueCat in a separate Android attribution field and to our backend; it does not send the Google advertising ID to RevenueCat. Automatic Meta purchase logging is disabled to avoid duplicate revenue reports.

The Android measurement choice applies to your account across Android devices. We store the current choice and its revision separately from shared subscription identifiers and check it before forwarding each eligible subscription event, including retries. Signing into an iPhone cannot grant Android measurement permission. Declining the prompt or turning measurement off in Profile stops new on-device Meta measurement immediately. If offline, the account-wide withdrawal is sent when the app reconnects; other Android devices obtain the current choice when they refresh. Once withdrawal reaches our backend, its Android attribution identifier is removed and new consent-dependent subscription deliveries are blocked. Events already delivered are not recalled.

Android’s advertising privacy settings also apply. When the advertising ID is unavailable or advertising tracking is limited, the Android SDK does not substitute another identifier to bypass that choice. Declining or withdrawing advertising consent does not change your subscription entitlement or access to app features.

We do not include health information, Apple Health or Health Connect records, workout details, meal logs, symptoms, Gut Scores, medical conditions, chat content, photos, names, email addresses, phone numbers or precise location in Android advertising events. Advertising processing is separate from the health, meal, coaching and photo features.

We retain the current account consent record to honor your choice and minimal event-delivery status to prevent duplicates. Account deletion removes the account’s consent and Android attribution identifier from our active backend. Meta and RevenueCat may retain information already processed under their own policies; contact us for deletion assistance.

Other Data Sharing

We do not sell your personal data to third parties. Ever. In addition to the AI processing and optional advertising measurement described above, we use the following trusted service providers to operate the app:

  • Supabase — secure database and authentication
  • RevenueCat — subscription management and billing status
  • Apple HealthKit and Android Health Connect — optional read-only health access. Android reads authorized steps, sleep, resting heart rate, active calories and completed exercise sessions as described above. Relevant summaries are used as described in this policy.
  • Google Places and Weather APIs — restaurant search using your query and optional location, and local weather using rounded coordinates, as described above

These providers process data only as needed to deliver their services and are contractually bound to protect your information.

Related recipe videos use YouTube services. Opening a video takes you to YouTube, where Google’s policies apply.

Optional Tribe features share your display name and group participation/check-ins with members of groups you join. If you grant contact access, you can select people to invite using your device’s messaging or sharing tools.

Health Data

Your health and nutrition data, including Apple Health metrics, is used to personalize your Trust My Gut experience. With your AI consent, summaries of relevant vitals may be processed by OpenAI to generate personalized recommendations, meal picks, and check-in notifications. We never share your health data with advertisers, data brokers, or anyone else beyond the service providers listed in this policy.

Data Retention and Account Deletion

We retain account data while your account is active. To delete your account in the app, open Profile, choose Delete Account, and follow the permanent-deletion confirmation steps. Temporary disabling is different from permanent deletion.

You can also request deletion without the app: email info@trustmygutapp.com from your account’s email address with the subject Delete my Trust My Gut account. Do not send your password. We may ask you to verify account ownership.

Account deletion removes your login and associated profile and synced app data from our active account systems, including saved onboarding answers, wellness entries, and chat information. It does not delete records in Apple Health or Health Connect. App stores and service providers may retain transaction, security, backup, or legally required records under their applicable retention policies; OpenAI retention is described above.

Deleting your app account does not automatically cancel an app-store subscription. Manage or cancel your subscription separately through Apple or Google Play.

Information saved to your account may include your profile, onboarding answers, meals, intentions, check-ins, wellness entries, saved Fiyah conversations and plans, and preferences. We store account data with Supabase to synchronize it across devices signed into the same account. Disabling a health connection stops new readings; it does not delete previously saved account information.

Children’s Privacy

Trust My Gut is not intended for children under 13. We do not knowingly collect personal information from children under 13.

Your Rights

You have the right to access, correct, or delete your personal data at any time. You can also revoke your AI data-sharing consent or Apple Health access in your Profile settings at any time. Contact us at info@trustmygutapp.com.

Changes to This Policy

We may update this policy from time to time. We will notify you of significant changes through the app.
