This Privacy Policy explains how eMeals, Inc ("Endurance by Design," "we," "us," or "our") collects, uses, shares, and protects information in connection with the Endurance by Design mobile application, Apple Watch companion app, and related services (together, the "Service"). It also describes the choices and rights you have regarding your information.
We care deeply about your privacy, especially your health and fitness data. We never use your Apple Health data for advertising, and we never share it with advertising or attribution partners. To run and grow the app, we do work with analytics and advertising partners using non-health data such as device identifiers and app activity. You can control this, as described in Advertising, analytics & attribution and Your rights & choices.
We collect the following categories of information:
When you create an account, we collect your name and email address. We support sign-in with Apple, Google, or email and password, managed through our authentication provider. If you use Sign in with Apple, you may choose to hide your email, in which case we receive an Apple-provided relay address.
To generate your plan, we collect information you provide, such as your sport(s), target race and date, experience level, weekly training hours, goals, swim access (pool/open water), and bike setup. As you train, we store your generated training plans, workouts, completion status, personal records, events, and training metrics.
With your permission, we read health and fitness data from Apple Health (HealthKit), and we receive workout data from watches you choose to connect (Garmin, Wahoo, or Polar). See Section 2 and Section 6 for details.
Subscriptions are processed by the Apple App Store. We do not receive or store your full payment card details. We receive subscription status and related transaction events from our subscription management provider to operate your subscription and any free trial.
We collect technical and usage information such as device type, operating system version, app version, language, IP address, and diagnostic or crash data. We also operate our own product analytics: the app sends us usage events (for example, which screens are opened and which features are used) so we can understand and improve the product. These events describe how you use the app and never contain health values. To measure and improve our marketing, we also collect a device identifier and, where you allow it, your device advertising identifier (IDFA), together with app events (for example, install, sign-up, trial start, and key in-app actions) and the marketing campaign, ad, or creator link you came from. See Section 7 for how this is used and how to control it. We never include Apple Health data in this marketing information.
Endurance by Design uses Apple HealthKit. With your explicit permission, we read data such as sleep, heart rate variability (HRV), resting heart rate, and workout history to calculate your daily readiness score and tailor your training recommendations. If you connect a watch (Garmin, Wahoo, or Polar — see Section 6), we also receive your completed workouts from it, including metrics such as duration, distance, heart rate, power, and lap or interval detail.
We treat all of this — HealthKit data and connected-watch workout data alike — as health and fitness data. In line with Apple's HealthKit requirements and our own commitments:
We use the information we collect to:
We do not sell your personal information for money. To run and measure our advertising, we do share certain non-health identifiers and app-event data with analytics and advertising partners, which may be treated as "sharing" or a "sale" for cross-context behavioral advertising under some U.S. state laws. You can opt out, as described in Section 9. We share information in these circumstances:
We rely on the following providers to deliver the Service. Each processes only the data necessary for its function, under its own terms and privacy practices:
If you choose to connect a Garmin, Wahoo, or Polar account, you authorize the connection through your watch provider's own secure sign-in, facilitated by our device-integration provider, Terra. Terra holds the connection to your watch provider — we never see or store your watch-account credentials. We store an account identifier and receive your completed activities, including metrics such as duration, distance, heart rate, power, and lap or interval detail, which we use to update your training log and metrics. You can disconnect at any time from within the app, which ends the connection and deletes the synced activity data we have stored from that provider. If you instead revoke access from your watch provider's side, we honor that automatically when Terra notifies us. Workouts you completed while connected remain in your training log as your own records.
We promote Endurance by Design through paid advertising, creator and influencer partnerships, and user-generated content. To understand which of these bring athletes to the app and to run our campaigns responsibly, we use attribution and advertising partners. This activity uses non-health data only.
We use AppsFlyer, a mobile measurement partner, to understand how people discover and install the app (for example, which ad, campaign, or creator link led to an install) and which key actions happen afterward. AppsFlyer processes data such as a device identifier, IP address, and app events on our behalf.
We advertise on platforms including Meta (Facebook and Instagram), TikTok, Google (including YouTube), and Apple Search Ads, and we may add others over time. To measure and optimize these campaigns, show relevant ads, and build similar-audience lists, we share limited information such as device and advertising identifiers (where permitted) and app events (for example, install, sign-up, or trial start). These platforms process that information under their own privacy policies.
When you arrive from a creator, influencer, or referral link, we use attribution data to credit that partner and to measure the campaign. This does not change what we collect about you beyond the marketing data described in Section 1.
Your Apple Health data and your connected-watch data (Garmin, Wahoo, or Polar via Terra) are never used for advertising or attribution and are never shared with AppsFlyer or any advertising platform.
On iOS we ask for your permission through Apple's App Tracking Transparency prompt before tracking you for advertising. If you decline, we do not use your device advertising identifier (IDFA) for cross-app tracking. You can change your choice anytime in iOS Settings > Privacy & Security > Tracking, and you can opt out of advertising-related sharing as described in Section 9.
We retain your information for as long as your account is active or as needed to provide the Service. You can delete your cloud training data from within the app at any time. When you delete your account or request deletion, we delete or de-identify your personal information, except where we are required to retain it to comply with legal obligations, resolve disputes, or enforce our agreements.
Depending on where you live, you may have rights to access, correct, delete, or port your personal information, and to object to or restrict certain processing. These include rights under the EU/UK GDPR and the California Consumer Privacy Act (CCPA/CPRA).
To exercise any of these rights, email support@endurancebydesign.com. We will not discriminate against you for exercising your privacy rights.
We use technical and organizational measures designed to protect your information, including encryption in transit, access controls, authentication, and rate limiting. The app is offline-first, keeping your data on your device with secure background backup. No method of transmission or storage is 100% secure, so we cannot guarantee absolute security.
The Service is not directed to children under 13 (or the minimum age required in your jurisdiction), and we do not knowingly collect personal information from them. We do not knowingly use any data from children for advertising or attribution tracking. If you believe a child has provided us information, please contact us and we will take appropriate steps to delete it.
We and our service providers may process and store information in countries other than where you live, including the United States. Where required, we use appropriate safeguards for such transfers. By using the Service, you understand your information may be transferred to and processed in these locations.
We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date above and, for material changes, provide additional notice within the app or by email. Your continued use of the Service after an update means you accept the revised policy.
