1. Information We Collect

When you use Pheidi, we collect the following information to provide and improve our service:

  • Account information: Email address and display name when you create an account.
  • Training data: Race times, running experience, schedule preferences, and goal race information you provide during onboarding and plan creation.
  • Usage data: How you interact with the app, including pages visited, features used, and workout completions.
  • Device information: Browser type, operating system, and screen size for compatibility and performance purposes.
  • Connected accounts (Strava): If you connect Strava activity sync, we store an encrypted access grant and import your running activities (distance, moving time, date, and type) to mark your plan's workouts complete. This is optional and separate from signing in with Strava — you can turn it off at any time, which revokes our access and deletes the imported Strava activity data. Raw imported activities are also automatically purged within 7 days on an ongoing basis, and Strava-sourced data is never used in AI features. We never post anything to your Strava account.
  • Health, fitness, and location data (mobile apps only): If you use the Pheidi Android or iOS app and grant permission, we access workout, distance, and heart-rate data through Google Health Connect or Apple HealthKit, and — for in-app run tracking — your device's GPS location. See Section 3 for details. The web app does not access this data.

2. How We Use Your Information

We use your information to:

  • Generate and personalize your training plan based on your fitness level, schedule, and goals.
  • Adjust your plan when you miss workouts, change your schedule, or update your race goals.
  • Send you training-related notifications and plan updates (if you opt in).
  • Improve the app's training algorithms and user experience.
  • Respond to support requests.

3. Health, Fitness, and Location Data (Mobile Apps)

The Pheidi Android and iOS apps can optionally connect to your device's health and location services. These integrations are off by default, require your explicit permission at the operating-system level, and can be revoked at any time. They are not available in, and are never used by, the web app or marketing site.

Health and fitness data

With your permission, the Android app reads from and writes to Google Health Connect, and the iOS app reads from and writes to Apple HealthKit. Specifically, we may:

  • Read exercise/workout sessions, distance, and heart rate so completed runs you record elsewhere can be matched against your Pheidi training plan.
  • Write workouts you complete in Pheidi back to Health Connect or HealthKit so your records stay in sync.

Health and fitness data accessed this way is used only to track and synchronize your training. It is never sold, never shared with third parties, and never used for advertising. You can manage or revoke this access at any time in your device's Health Connect or Apple Health settings. Our use of Health Connect data follows the Health Connect Permissions policy, and we request only the permissions needed for the features above.

Location data

Pheidi is adding an in-app run-tracking feature. When it ships, and only if you grant the OS location permission, the mobile app will use your device's GPS location to record the route, distance, and pace of runs you actively choose to track. Location is collected only while you are recording a run, is used solely to log that run against your plan, and is never sold, shared with third parties, or used for advertising. The web app and marketing site do not access GPS or device location.

Google Play Data Safety

These integrations correspond to the following declarations on the Google Play Data Safety form:

  • Health and fitness — collected and accessed with permission; not shared with third parties; optional; used for app functionality. Encrypted in transit.
  • Location (precise) — collected with permission for the run-tracking feature; not shared with third parties; optional; used for app functionality. Encrypted in transit.

We do not collect this data for advertising or analytics, and you can request deletion of any stored health, fitness, or location data at any time (see Section 8).

4. Information We Do Not Collect

  • We do not collect payment information (Pheidi is free).
  • We do not use advertising cookies, and we do not sell, rent, or trade your personal data.
  • Apart from the optional mobile integrations described in Section 3, we do not access your device's location or health data — and the web app accesses neither.

5. Artificial Intelligence and Your Data

We never use your data to train AI. Your training data, your Strava activities, and any health data you connect are used only to generate and adjust your own training plan. We do not use them — or any data derived from them — to train, fine-tune, evaluate, or otherwise improve any artificial-intelligence or machine-learning model, and we never sell or provide your data to a third party for that purpose.

Your plan is produced by transparent, rule-based logic grounded in published sports-science research and established coaching methodology, not by an AI model deciding your training. Where Pheidi offers an optional AI assistant that can read your plan at your request, your data is used only to answer you in the moment; it is not retained for model training, and data that originates from a connected service such as Strava is withheld from those AI features.

6. How We Share Your Information

We do not sell, rent, or trade your personal information. We may share data with:

  • Service providers: Hosting, analytics, and authentication services that help us operate Pheidi. These providers only access data necessary to perform their functions.
  • Legal requirements: If required by law, regulation, or legal process.

The service providers above act only as data processors with limited, contractual access to perform these functions on our behalf; they are not independent third parties and may not use your data for their own purposes. We never sell, rent, trade, or share your health, fitness, or location data for advertising.

7. Data Storage and Security

Your data is stored securely using industry-standard encryption in transit (TLS) and at rest. We use trusted cloud infrastructure providers and follow security best practices to protect your information.

8. Your Rights

You have the right to:

  • Access the personal data we hold about you.
  • Correct inaccurate or incomplete data.
  • Delete your account and all associated data.
  • Export your training data.
  • Disconnect Strava activity sync from Settings, which revokes our access and removes imported activity data. You can also revoke access from your Strava account's connected-apps settings.

To exercise any of these rights, contact us at the email below.

9. Cookies and Analytics

We use Google Analytics 4 (GA4) to understand how visitors use our marketing site. GA4 uses cookies to collect aggregated, pseudonymous usage data such as pages visited, session duration, and referral source.

If you are in the EU, EEA, or Switzerland, we apply Google's Consent Mode v2 with a region-scoped default-deny: no analytics cookies are set until you accept. A first-visit banner asks for your choice. We do not use advertising cookies anywhere.

Changing your choice: Your preference is saved in your browser's local storage under the key pheidi_consent_v1. To revoke or change your consent, clear that key (via your browser's site data tools) and the banner will reappear on your next visit. You can also opt out of GA at any time using your browser's cookie settings or a browser extension like Google Analytics Opt-out.

10. Third-Party Links

Our articles and site may contain links to external websites and research papers. We are not responsible for the privacy practices of those sites.

11. Children's Privacy

Pheidi is not directed to children under 13. We do not knowingly collect personal information from children under 13. If we learn that we have collected such information, we will delete it promptly.

12. Changes to This Policy

We may update this privacy policy from time to time. We will notify you of significant changes by posting a notice on our site or sending an email. The "Last updated" date at the top of this page indicates when this policy was last revised.
