隱私權政策

Privacy Policy

1. What we collect

Nothing. KINETIC requires no sign-up, creates no account, and has no backend. Everything the app produces stays on your device, where we have no access to it.

The app contains no third-party analytics, advertising SDKs or tracking code. We do not know who installs the app or how it is used.

2. What the app uses on your device

Health data (HealthKit)

• Read: heart rate, resting heart rate, one-minute heart rate recovery, date of birth, active energy, workouts — used to calculate your heart-rate zones, show live heart rate during a session, and total your time in each zone.
• Write: workouts, heart rate and active energy, so your sessions appear in Health and Fitness.
• Access is controlled by iOS and watchOS; you can revoke it at any time in the Health app.

Camera and photos

• You may attach photos to a workout report (a whiteboard, your setup). They are stored locally in the app and never uploaded.

What you enter

• Workout notes, session detail (movement, sets, reps, weight) and personal settings (age, max heart rate, resting heart rate, lactate threshold, zones, heart-rate ceiling) — all stored locally.

3. Where data is stored

• Workouts, notes and settings: local storage on your iPhone and Apple Watch.
• Heart rate and workouts are also written to Apple Health, governed by Apple's privacy mechanisms.
• Transfers between iPhone and Apple Watch use Apple's WatchConnectivity directly between your two devices — never through us or any server.
• If you use iCloud device backup, app data may be included in that backup and is handled by Apple under its own privacy policy.

4. HealthKit commitments

• We do not use HealthKit data for advertising, marketing or similar purposes.
• We do not sell, disclose or share HealthKit data with any third party.
• HealthKit data is used solely for the app features described in section 2.

5. Sharing

We share, sell and trade nothing, because we receive nothing.

The one exception is initiated by you: when you use the in-app share feature to export a workout card, that image is handed to the app you choose, and that app's privacy policy applies from then on.

6. Your controls

• Revoke health access: Health › Sharing › Apps and Services › KINETIC.
• Delete a single workout: swipe to delete in the app's history list.
• Delete everything: remove the app. Data already written to Health must be deleted separately in the Health app.
• Revoke camera access: iOS Settings › KINETIC › Camera.

7. In-app purchases and tips

KINETIC offers one-time tips for people who want to support development. There are no subscriptions and no recurring charges; all transactions are handled through Apple's In-App Purchase.

• We never receive your payment details. Card numbers, billing addresses and Apple Account information are collected and processed by Apple under Apple's Privacy Policy.
• The app only verifies with Apple, on your device, whether a purchase is valid. That result never leaves your device and does not identify you to us.
• We have no way of knowing who has tipped — there is no account system and no server to record it.
• Refunds are handled by Apple at reportaproblem.apple.com. We cannot issue refunds ourselves.
• Tipping changes nothing else in this policy and gives us no additional data.

8. The Garmin edition: the KINETIC watch app and KINETIC Link

KINETIC also comes in a Garmin edition made of two apps: "KINETIC" on the Garmin watch (Connect IQ) and "KINETIC Link" on the iPhone. Neither has an account or a server, and every other section of this policy applies to them; the differences are listed here.

What the watch app uses on the watch

• Heart rate (Sensor permission): to determine your zone live and total your time in each zone.
• Profile (User Profile permission): reads the birth year, resting heart rate and max heart rate you set in Garmin, to calculate your zones. Read only, never modified.
• Activity recording (FIT permission): each session is saved on the watch as a FIT activity and syncs to your Garmin Connect account through Garmin's own mechanism. That data is handled by Garmin under Garmin's privacy policy; we never receive it.
• Communications permission: exchanges settings and live data with KINETIC Link on your iPhone. Messages are relayed by the Garmin Connect app on your phone and travel only between your watch and your phone — never through any server of ours.

What the iPhone app (KINETIC Link) uses on the phone

• Bluetooth: Garmin's Connect IQ SDK needs Bluetooth access to talk to the watch through Garmin Connect.
• Health data (HealthKit, read only): date of birth, resting heart rate, max heart rate and one-minute heart-rate recovery, to calculate your zones. KINETIC Link never writes to Apple Health.
• Camera, photos and what you enter: as in section 2.
• In-app purchases (tips): as in section 7 — one-time, handled by Apple, unlocking nothing; we never receive payment details.
• Storage: workouts, notes and settings live in the app's local storage on your iPhone.

Data handled by Garmin Connect and the Connect IQ store itself is governed by Garmin's privacy policy.

9. Children

KINETIC is a training tool and is not directed at children under 13. We do not knowingly collect data from children — we collect no data from anyone.

10. Changes

If this policy changes we will update this page and the date above. Should any future feature transmit data (cloud sync, for example), this policy will be updated and the change made clear in the app before that feature ships.
