This Privacy Policy explains how VAUGHN TECHNOLOGIES LLC (“Vaughn,” “we,” “us,” or “our”) collects, uses, shares, and protects information in connection with the Vaughn application (on the App Store as Vaughn | Train. Play. Recover.) and related services (the “Service”). We built Vaughn to help athletes and everyday people train smarter, and we treat the data that makes that possible, including health and wearable data, with care.
By creating an account or using the Service, you agree to this Policy. If you do not agree, please do not use the Service.
1. Information We Collect
Information you provide
Account information: your name, email address, your login code, and the city you give us at signup.
Profile information: details you choose to add, such as age, biological sex, sport, and training preferences, which help personalize your readiness and recovery insights.
Training and activity data: workouts, sets, exercises, sports and activities you log (including type, duration, and intensity), and notes.
Check-in inputs: optional self-reported signals such as sleep, soreness, and stress.
Communications: messages you send us and support requests.
Purchases: your subscription and purchase history. Apple or Stripe tells us whether your membership is active; we never see your full card number.
Health and wearable data
If you choose to connect a wearable device or health platform (today, Oura and Polar), we collect the health and activity metrics you authorize, which may include sleep duration, heart rate, heart rate variability (HRV), resting heart rate, body temperature trends, and activity or readiness metrics. We collect this data only after you explicitly connect the device and grant permission, and only the categories needed to power your readiness and recovery insights. You can disconnect a device at any time.
Information collected automatically
Device and usage data: app version, device type, and basic usage events needed to operate and improve the Service.
Log data: technical logs for security, debugging, and reliability.
Analytics: we use Google Analytics to measure how the app and website are used (for example, which screens are opened). It is not linked to your name or email, and we do not use it for advertising. We do not track you across other companies’ apps or websites.
Heart rate from a Bluetooth strap
If you pair a heart rate strap with the Vaughn app, we record your heart rate during workouts and heart rate tests, including the beat-to-beat intervals used to calculate heart rate variability (HRV), and save it to your training record.
2. How We Use Information
To provide the Service, computing your readiness, recovery, and training insights.
To personalize your experience based on your profile, training history, and connected devices.
To operate, maintain, secure, and improve the Service.
To communicate with you about your account, updates, and support, and to send you news about Vaughn by email. You can unsubscribe from marketing email at any time with the link in each email.
To comply with legal obligations and enforce our terms.
We do not sell your personal information or your health data. We do not use health or wearable data for advertising, and we do not use it for any purpose other than providing and improving the Service you asked for.
3. Health & Wearable Data: Special Commitments
Health and wearable data is sensitive, and some of it reaches us through third-party platforms whose rules we honor. Specifically:
We use data obtained from connected platforms (today, Oura and Polar) solely to provide health and fitness features within the Service.
We do not use this data for advertising, marketing, data brokering, or resale, and we do not disclose it to third parties for those purposes.
We do not share this data with any third party except the service providers that help us operate the Service (see Section 5), or as required by law with your knowledge where permitted.
You may revoke a device connection at any time, which stops future collection from that source.
Data from each connected platform is handled in accordance with that platform’s API terms. This version of the app does not use Apple Health (HealthKit).
4. AI Features
Two features use artificial intelligence: building a workout and reading a program you add (pasted or photographed). If you photograph a program, everything in the photo is sent, so leave out anything you do not want included. When you use one of them, we send the information it needs, which can include your training history, profile details and what you enter, to Anthropic, the company behind the Claude AI models, which processes it and returns the result.
We ask for your permission in the app before any of your information is sent to Anthropic, and you can turn AI features on or off at any time in Menu, Account.
With AI features off, logging your training and seeing your numbers still work; only building a workout and reading a program are unavailable.
Information sent for AI features is never used for advertising and never sold.
5. How We Share Information
We share information only in these limited circumstances:
Service providers. Vendors that host and operate the Service under contract and on our instructions, for example, cloud hosting and database infrastructure, application/workflow processing, and deployment. These providers may process data only to perform services for us, and must protect it with the same or equal protection as this Policy. They include:
Anthropic, for AI features, only when you use them and have allowed it (see AI Features).
Google (Google Analytics), for usage measurement.
Stripe, which processes payments made on our website.
Apple, which processes subscriptions bought in the app through the App Store.
Payments are handled by Stripe or Apple; we never see or store your full card number.
Legal and safety. When required by law, or to protect the rights, safety, and security of our users, the public, or Vaughn.
Business transfers. In connection with a merger, acquisition, or sale of assets, subject to this Policy.
With your direction. When you ask us to share specific information.
6. Third-Party Integrations
The Service can connect to third-party platforms at your choice, today Oura and Polar, signed in through your own account, plus Bluetooth heart rate straps paired with your phone. Your use of those platforms is governed by their own privacy policies and terms. Connecting or disconnecting them is always your decision, and disconnecting stops future data collection from that source.
7. Data Retention
We keep your information for as long as your account is active or as needed to provide the Service, and afterward only as required to comply with legal obligations, resolve disputes, and enforce our agreements. When you delete your account, we delete or de-identify your personal and health data after the 7-day window, except where retention is required by law.
8. Your Rights & Choices
Access and correction. You can view and update much of your information in the app.
Deletion. You can delete your account in the app (tap your avatar, then Account, then Delete account) or by emailing us. Deletion takes effect after a 7-day window in which you can change your mind, and is then permanent. Deleting your account does not cancel an App Store subscription; cancel that in your Apple ID settings.
Disconnect devices. You can revoke any wearable or health-platform connection at any time.
Export. You can request a copy of the personal data you have provided.
To exercise any of these, contact us at support@coachvaughn.ai. Depending on where you live, you may have additional rights under laws such as the California Consumer Privacy Act (CCPA/CPRA) or the EU/UK General Data Protection Regulation (GDPR), including the right to know, delete, correct, and opt out of certain processing. We honor these rights where they apply and do not discriminate against you for exercising them.
9. Security
We use administrative, technical, and organizational safeguards designed to protect your information, including access controls and secure storage of credentials and connection tokens. No method of transmission or storage is completely secure, but we work to protect your data and to promptly address issues if they arise.
10. Children & Minors
Vaughn is for people aged 16 and older.
The Service is not directed to anyone under 16, and we do not knowingly collect personal information from anyone under 16.
For members aged 16 and 17, we expect a parent or guardian to agree to our Terms and to any subscription.
If you believe someone under 16 has provided us personal information, contact us at support@coachvaughn.ai and we will delete it.
11. International Users
We operate from the United States, and your information may be processed in the United States and other countries where our service providers operate. Data protection laws in these countries may differ from those in your country. Where required, we take steps to provide appropriate safeguards for cross-border transfers.
12. Changes to This Policy
We may update this Policy from time to time. When we make material changes, we will update the “Last updated” date and, where appropriate, provide additional notice. Your continued use of the Service after changes take effect means you accept the updated Policy.
