Privacy Policy

Information MyFuel processes

MyFuel may process account information such as your email address, a verified delivery email you choose for reports, and identity information returned by Sign in with Apple. A Sign in with Apple address may be an Apple private-relay address if you chose Hide My Email. MyFuel also processes nutrition, food, meal, hydration, goals, supplements, and related history that you choose to record. If you connect Apple Health, MyFuel may also process the specific health and fitness information you choose to share as described below.

Food photos

Food and Nutrition Facts photos are sent for analysis when you choose photo logging. MyFuel is designed not to keep a permanent meal-photo archive. Structured results you confirm can be stored in your Diary and Food Library, while the image itself is not intentionally retained as part of your history.

Voice input

If you use microphone input, MyFuel processes the audio you choose to record so it can transcribe your food command. MyFuel does not intentionally keep microphone audio as part of your food history. Typed or transcribed food commands may be sent for AI-assisted nutrition estimation when needed.

Apple Health, Health Connect, and health information

On supported Apple devices, MyFuel can connect with Apple Health when you choose to allow it. MyFuel may save supported nutrition and hydration information that you log in MyFuel to Apple Health, including dietary energy, protein, carbohydrates, total fat, and water.

When you grant read access, MyFuel may also read health and fitness information you choose to share, including steps, active energy, basal or resting energy, exercise minutes, workouts, body weight, sleep, resting heart rate, heart-rate variability (HRV), and VO₂ max.

On supported Android devices, MyFuel can connect with Health Connect when you choose to allow it. MyFuel writes only nutrition (dietary energy, protein, carbohydrates, and total fat) and hydration that you log in MyFuel. It may read only steps, active and basal energy, exercise sessions and workouts, body weight, sleep, resting heart rate, HRV (Health Connect reports RMSSD), and VO₂ max. MyFuel does not import Health Connect nutrition or hydration.

MyFuel uses Apple Health or Health Connect information to show Activity & Recovery context in the app and, for eligible MyFuel Pro users, to make Coach's Reports more relevant. MyFuel sends only compact summaries needed for those features to its service; it does not upload raw Apple Health or Health Connect sample streams. Permissions are optional and controlled by you in the relevant health settings. If a type is unavailable or not shared, MyFuel treats it as unavailable rather than zero.

MyFuel does not use Apple Health information for advertising or marketing, does not sell Apple Health information, and does not store personal health information in iCloud. MyFuel does not provide medical diagnosis or medical advice, and it does not claim that one tracked behavior caused a change in another health metric. Nutrition estimates, especially AI estimates, can be imperfect. Review important information before relying on it.

Notifications and reminders

If you choose to enable notifications on iPhone, MyFuel can schedule optional reminders such as a midday logging check-in, a Coach report-ready notice, and a Finish Day reminder. These reminders are scheduled locally on your device. MyFuel may also send privacy-limited notifications for incoming Community friend requests and direct messages; direct-message notification payloads do not include the message body.

Notification preferences are stored on your device. For Community notifications, MyFuel sends your APNs device token to the authenticated device-registration endpoint and stores a one-way token hash plus the provider endpoint associated with your account and app installation. Other users cannot access this registration data. Notification permission is optional and is not required to use MyFuel. You can turn MyFuel notifications off in MyFuel or in iOS Settings, and signing out removes the installation registration.

Daily Finish Email

Daily Finish Email is an optional transactional report that you can enable or disable in MyFuel Settings. MyFuel sends it only to a verified address associated with your authenticated account or to a different delivery address after you complete MyFuel's verification challenge. An Apple private-relay address marked verified by the authentication provider is eligible.

MyFuel stores account-scoped delivery status, a normalized delivery address when needed, verification timestamps, and short-lived challenge controls. Verification codes are single-use and are not stored in raw form. MyFuel does not use this feature for purchased lists, unsolicited marketing, or arbitrary third-party recipients.

Amazon Simple Email Service processes delivery and provider events. Hard-bounce and complaint information may be retained and used to prevent further optional email to an affected destination. Contact support@myfuel.pro to report abuse or an email-delivery concern.

Support and lifecycle email

When you submit an in-app support request, MyFuel stores the category, subject, messages, request number, status, timestamps, platform and app version/build, and a verified reply email when available. Support messages form a durable conversation. Customer acknowledgement and response email is sent only to a verified address. Support operators receive the request content needed to respond through a secure, time-limited, single-use link.

MyFuel may send essential service messages about support, verified purchases, subscription access, account changes, and security. Optional promotional email is separate, is off when the preference is unset, and may be disabled without turning off essential service email. MyFuel does not advertise discounts unless an actual eligible store offer exists.

Community phone verification

If you choose phone verification for MyFuel Community, your mobile number and the one-time code you submit are processed by a specialized phone-verification provider to send and validate the code. MyFuel limits this feature to U.S. and Canadian numbers.

MyFuel does not retain the raw phone number or verification code in Community storage. After successful verification, MyFuel retains a masked last four digits and a keyed, non-readable index used to prevent the same verified number from being claimed by another Community account.

Service providers

MyFuel uses Amazon Web Services for authentication, hosting, APIs, compute, data storage, and transactional email delivery, plus a specialized provider for optional Community phone verification. AI-assisted food analysis and transcription may use OpenAI from the server side. Apple provides Sign in with Apple and Apple Health/HealthKit. These providers process data as needed to deliver their respective services.

Authentication and device storage

MyFuel uses Amazon Cognito for authentication. To keep you signed in, authentication session information can be stored locally on the device you use. Signing out removes MyFuel's locally stored session. Anyone with access to an unlocked device may be able to access an active session.

How information is used

Information is used to authenticate your account, display your Diary and Food Library, calculate recorded nutrition and hydration, provide Activity & Recovery context, create eligible Coach's Reports, analyze foods you ask MyFuel to analyze, improve logging speed through reusable foods, and operate and secure the service.

Data retention

Structured nutrition, hydration, supplement, and related MyFuel history is retained so your Diary remains useful unless it is deleted through supported product or administrative processes. Compact Apple Health summaries sent to MyFuel's service for supported features may be retained with the related MyFuel record as needed to provide that feature. Account-scoped delivery-email preferences and verification status may be retained while the account exists; pending challenges expire after a short period. Support messages may be retained in minimum form for a limited customer-service, security, or legal purpose after account deletion and are detached from the active-account index when deletion is detected. Food photos are not intended to be retained as a permanent archive. Operational logs are designed not to contain passwords, authentication tokens, API keys, raw response-link tokens, raw email verification codes, or photo image data.

Changes and contact

This policy may be updated as MyFuel adds features or changes service providers. A revised policy will show a new effective date on this page. MyFuel is operated by AiAir LLC. For privacy questions, contact support@myfuel.pro.
