HIITTracker – Privacy Policy
Effective date: September 19, 2025
This Privacy Policy explains how HIITTracker ("the App", "we", "us") handles data. HIITTracker is a native iOS/watchOS app that connects to Apple Watch to display and record workout and heart rate information, and optionally controls Spotify playback on your iPhone. We do not operate any backend servers; data is stored on your devices and/or in Apple’s Health app when you choose.
What We Collect and Where It Lives
Health & Fitness data (on-device and Health app only)
- Heart rate, active energy, walking/running distance read via HealthKit; workout records written to HealthKit when you save a workout.
- Stored locally in the app’s on-device database (Core Data) for your workout history and charts; may also be saved to Apple Health if you permit.
- Not transmitted to our servers (we have none) and not shared with third parties.
Workout metadata (on-device)
- Interval types, start/end times, heart rate samples with timestamps, computed averages/maxima, and optional calories.
- Stored locally on your iPhone; can be deleted in‑app (where available) or by deleting the app.
Preferences (on-device)
- UI theme, toggle states (e.g., show controls, keep screen awake), countdown settings, Apple Watch enablement, max heart rate and alert preference.
- Stored in UserDefaults on your device.
Connectivity state (on-device only)
- Watch/iPhone connection status, latest heart rate value, recent workout state, and a locally generated workout identifier used to link sessions between iPhone and Apple Watch.
Spotify connection data (on-device and Spotify)
- If you opt in, the app stores your Spotify access token securely in the iOS Keychain and interacts with Spotify’s SDK and Web API to control playback and fetch track metadata and artwork.
- We do not receive your Spotify account details. Communication is between your device and Spotify. Track metadata (name, artist, album, artwork URL) may be fetched from Spotify when you request it.
How We Use Data
- Provide core functionality: show live heart rate, guide intervals, compute workout metrics, and render charts.
- HealthKit: read allowed data types to display heart rate and metrics; write workouts to Health app when you save. Your consent is required and can be changed anytime in iOS/watchOS Settings.
- Spotify (optional): control playback and fetch track info/artwork when you connect. If you don’t connect Spotify, no Spotify data is used.
What We Don’t Do (Currently)
- No analytics/ads SDKs (currently): we do not currently use third‑party analytics or advertising SDKs, and we do not track you across apps or websites.
- No data sale or broker sharing: we don’t sell your data or share it with data brokers.
- No server storage: we don’t run servers; we don’t upload your data.
HealthKit Disclosure
- The App uses HealthKit to read heart rate, active energy, and distance, and to write workouts if you allow.
- Health data is used solely to provide health/fitness features in the App and is not used for advertising, marketing, or tracking.
- Health data is not shared with third parties. You can control access in the Health app and iOS/watchOS Settings.
Optional Analytics (Future)
We currently do not collect analytics or tracking data. If we introduce optional, privacy‑respecting analytics in the future, we will:
- Request your explicit consent before enabling any analytics and provide a clear in‑app explanation;
- Allow you to change your choice at any time in Settings; default will be off until you opt in;
- Collect only non‑HealthKit diagnostic and usage data needed to improve the app;
- Never include Health data in analytics and never use Health data for advertising or tracking;
- Update this policy and our App Store privacy disclosures before any such change takes effect;
- If any feature constitutes “tracking” under Apple’s rules (e.g., cross‑app tracking, IDFA), we will display Apple’s App Tracking Transparency (ATT) prompt and only proceed after opt‑in.
Data Sharing
- Apple: Health data you choose to save is stored by Apple in the Health app under your control. WatchConnectivity syncs state between your watch and iPhone using Apple’s secure channels.
- Spotify (optional): If connected, your device communicates with Spotify’s services to control playback and fetch metadata/artwork. Spotify’s handling of data is governed by Spotify’s policies.
Security
- On-device storage: Workout history and preferences are stored locally in the app sandbox (Core Data/UserDefaults).
- Credentials: Spotify access token is stored in the iOS Keychain.
- Transport: Communications to Spotify use HTTPS. iPhone–Watch sync uses Apple’s WatchConnectivity with system-level protections.
Your Choices and Controls
- Permissions: Grant or revoke Health permissions anytime in iOS/watchOS Settings > Privacy & Security > Health.
- Spotify: Connect/disconnect anytime in the App’s Settings; remove the token by disconnecting.
- Analytics consent (future): If optional analytics are introduced, you can opt in/out anytime in Settings.
- Delete data:
- Delete individual workouts in‑app (where provided) or remove all local data by deleting the App.
- Delete Health data in the Health app (browse to the workout or data type and delete).
- Opt-out: Don’t enable Spotify controls to avoid any Spotify interactions.
Data Retention
- Local data: Retained on your device until you delete it or uninstall the App.
- Health data: Retained in the Health app under your control.
- Spotify token: Retained in Keychain until you disconnect Spotify or uninstall the App.
Children
The App is intended for general fitness use and is not directed to children under 13. Do not use Health features for children without appropriate permissions and supervision.
Not Medical Advice
HIITTracker is a fitness tool, not a medical device. It does not diagnose, treat, cure, or prevent any disease. Consult a healthcare professional for medical concerns.
International Users and Rights
Because we do not operate servers and data remains on your devices and/or the Health app, requests to access, port, or delete data are performed directly by you on your device (e.g., delete workouts in‑app, adjust Health permissions, or remove the App). If you need assistance, contact us.
Changes to This Policy
We may update this policy to reflect product or legal changes. We will update the “Effective date” above and, where appropriate, notify you in‑app.
