Privacy Policy
Runsense provides an AI-powered running coach via SMS, email, and the Runsense iOS app. This Privacy Policy explains what information we collect, how we use it, who we share it with, where it is processed, and the choices and rights you have over it.
Who We Are
Runsense LLC, a Colorado limited liability company ("Runsense", "we", "us", or "our"), provides the service and is responsible for the personal data described here.
- Contact: support@runsense.ai
- Location: Longmont, Colorado, USA
Information We Collect
1. Information you provide
- Phone number
- Email address
- Messages you send to Runsense (e.g. how you feel, training details)
2. Apple Health (HealthKit) — iOS app only
When you use the Runsense iOS app and grant HealthKit access, we collect from Apple Health on your device:
- Workouts (activity type, duration, distance, timestamps)
- Sleep analysis (per-stage breakdown, total time asleep)
- Resting heart rate
- Heart rate variability (HRV)
This data flows from your device to Runsense via the iOS app's authenticated connection. The Runsense iOS app does not write back to Apple Health; we read only. We collect the workouts present in Apple Health regardless of which app recorded them (for example Apple Watch, COROS, Garmin, or the Strava app writing to Apple Health). When the same workout reaches us from more than one source, we keep one copy and mark the others as duplicates.
Your health and fitness data is special category data under GDPR / UK GDPR. We process it only with your explicit consent, which you give when you connect Apple Health and can withdraw at any time — see "Legal Bases" below.
3. Automatically collected information
- Basic usage data (e.g. when messages are sent/received)
- Website analytics via Umami, a cookieless, privacy-focused service that does not set cookies or collect personal data
How We Use Information
We use your information to:
- Provide personalized coaching based on your training data
- Respond to your messages
- Send you coaching via SMS or email based on your preference
Apple Health data
Your Apple Health data is used solely to generate personalized coaching for you. We do not use it to train, improve, or benchmark AI or machine learning models, nor do we use it for product analytics or aggregate research. It is retained as part of your training history; you can delete it at any time (see "Your Rights"). No third-party analytics or advertising service receives Apple Health data.
Legal Bases (GDPR / UK GDPR)
Where GDPR or UK GDPR applies, we rely on the following legal bases:
| Purpose | Data | Legal basis |
|---|---|---|
| Providing the coaching service, responding to you, and sending coaching over your chosen channel | Phone number, email, your messages | Performance of our contract with you — Art. 6(1)(b) |
| Generating personalized coaching from your training and health data | Workouts, sleep, resting heart rate, HRV | Your explicit consent — Art. 9(2)(a). You give it when you connect Apple Health and can withdraw it at any time. |
| Keeping the service secure and reliable | Basic usage / security logs | Our legitimate interests — Art. 6(1)(f) |
Withdrawing consent does not affect processing carried out before you withdrew it. If you withdraw consent for your health data, we can no longer generate training-data-based coaching, and we'll tell you what that means for your account.
Communications
By using Runsense, you agree to receive coaching messages via SMS and/or email based on the communication preference you choose.
- Message frequency varies based on your interaction and training activity
- For SMS: message and data rates may apply
- You can opt out of SMS at any time by replying "STOP"
- Reply "HELP" for assistance
- You can opt out of email or pause coaching from your account settings page
Sharing of Information
We do not sell your personal information.
We will not share your mobile phone number or any information collected via SMS with third parties or affiliates for marketing or promotional purposes.
We share information with the service providers below solely to operate Runsense. Each processes your data only on our instructions, under a data processing agreement:
| Provider | Purpose | Location |
|---|---|---|
| OpenAI | Generating coaching responses (real-time processing only; not used to train models) | United States |
| Twilio | SMS delivery | United States |
| Resend | Email delivery | United States |
| Render | Cloud hosting and database | United States |
| Apple | iOS push notifications and App Store billing | United States |
International Data Transfers
Runsense is operated from the United States. If you use Runsense from outside the United States, your information is transferred to and processed in the United States. Where required, we rely on data processing agreements with our providers — including, where applicable, the EU-US Data Privacy Framework and the European Commission's Standard Contractual Clauses — as the safeguard for those transfers. You can request a copy of the relevant safeguards by contacting us.
Data Retention
We keep your personal data for as long as your account is active. When you delete your account — in the iOS app under Settings → Account → Delete account, or by contacting us — your data and training history are deleted, and copies in routine backups are purged within 30 days. We retain only what we are legally required to keep.
Data Security
We take reasonable technical and organizational measures to protect your information, but no system is completely secure.
Your Rights
Depending on where you live, you have rights over your personal data, which may include the right to:
- Access the personal data we hold about you
- Correct inaccurate data
- Delete your data
- Restrict or object to how we process it
- Receive your data in a portable format
- Withdraw consent where we rely on it
- Lodge a complaint with your data protection authority — in the UK, the Information Commissioner's Office (ico.org.uk); in the EEA, your local supervisory authority
To exercise any of these, email support@runsense.ai; we respond within 30 days. You can also act directly: reply "STOP" to end SMS; pause or stop email from your account settings; disconnect Apple Health on your iPhone at Settings → Privacy & Security → Health → Runsense (the app stops collecting immediately); or delete your account in the iOS app.
Automated Coaching
Your coaching is generated by automated AI systems from the information available to them. These systems produce guidance and suggestions; they do not make decisions that produce legal or similarly significant effects concerning you. Coaching is not medical advice — see our Terms of Service.
Children
Runsense is not directed to, and we do not knowingly collect personal data from, anyone under 16. If you believe a child has provided us data, contact us and we will delete it.
Changes
We may update this policy from time to time. Continued use of Runsense means you accept the updated policy.
