Privacy Policy

1. Scope and principles

This Privacy Policy applies to the SkippingFit app, website, support, and related services provided by Beijing Nvwa City Technology Co., Ltd. ("we", "us", or "our"). We process personal information lawfully, fairly, transparently, and only to the extent necessary for the stated purposes.

SkippingFit is a jump rope training aid. Basic training can be used without signing in. Workouts and achievements remain local unless a Pro user explicitly enables private iCloud sync. SkippingFit accounts are used for public identity and collaboration.

2. Information we collect and use

Training and record information

The app processes jump count, duration, pace, estimated calories, time, training mode, input source, and detailed workout records on device. Leaderboard scores are submitted to Apple Game Center, not SkippingFit servers. For friend challenges, SkippingFit servers receive only the score, nickname, result, rhythm timing, and limited service-integrity information needed for the feature. Raw workout detail files are not uploaded unless you choose to send them for support.

Device and diagnostic information

To keep the service stable, secure, and fair, we may process limited technical and diagnostic information about the device, app, network, and service use. This information is used for troubleshooting, product improvement, service protection, and fair participation in rankings and promotions.

Account, purchase, and support information

When you sign in, subscribe, restore purchases, join rankings, or contact support, we may process account identifiers, App Store transaction verification results, support emails, and screenshots, recordings, logs, or descriptions you submit. App Store purchases are not bound to a SkippingFit account.

3. Device permissions and local recognition

• Camera: Used for pose recognition, positioning guidance, and jump counting. Routine recognition is processed on device and raw camera video is not uploaded.
• Motion sensors: Used to read motion signals from iPhone, AirPods, or Apple Watch for jump recognition, rhythm analysis, and training feedback.
• Apple Health: With permission, SkippingFit saves jump-rope workouts to Apple Health and uses Apple Watch active energy to refine calorie records. We do not collect or record heart rate. You can manage permissions in system settings. Health data stays on your devices and in Apple Health, is excluded from the app’s iCloud sync, and is not sent to our servers or advertisers or used for advertising.
• Notifications, Bluetooth, local network, and network: Used for reminders, device connection, iPhone and Apple Watch communication, private iCloud sync, rankings, membership verification, and challenge links.
• Photos: Used only when you actively save a recording, result card, or training highlight.

You can disable permissions in system settings. Some features may stop working after permission is disabled, but unrelated basic features remain available.

4. Private iCloud sync, rankings, and friend challenges

SkippingFit is local-first. When a Pro user explicitly enables sync, workouts and achievements are stored incrementally in that user's private Apple iCloud database. SkippingFit servers do not receive those iCloud records. SkippingFit accounts are used for public identity, friend challenges, and future collaboration features, not for training-data ownership.

Leaderboards display your Game Center nickname, avatar, score, and rank. Apple processes Game Center information under its privacy rules. Friend challenges may display your SkippingFit nickname, score, result, and relevant timing. We may reject invalid challenge submissions to protect fair play.

5. Sharing, processors, and third-party services

We do not sell your personal information. To provide App Store purchases, Apple Health, notifications, crash diagnostics, server hosting, support email, and security protection, we may share or entrust limited information to Apple or infrastructure, email, and diagnostic providers. They must process information only for agreed purposes and under security requirements.

We may disclose information when required by laws, regulators, judicial procedures, public safety, user protection, or protection of our lawful rights and interests.

6. Retention and security

We keep information only for the period necessary for the purposes described here. Workout records and achievements are stored locally by default; optional iCloud copies are controlled through the user's Apple iCloud account. Account, transaction-verification, challenge, and security logs are retained as needed and deleted or anonymized when their purpose or legal retention period ends.

We use reasonable organizational and technical safeguards to protect information. No internet service is absolutely secure, so please protect your device, account, and verification codes.

7. Your rights

Within the scope allowed by applicable law, you may request access, correction, deletion, withdrawal of authorization, account closure, privacy explanations, or restrictions on automated decisions, ranking display, and marketing notifications. Some requests may require identity verification.

You can manage some rights in the app, iOS settings, App Store subscription management, or by contacting us at the email below.

8. Minors

SkippingFit is intended for users who can train safely. Minors should use the service with guardian consent and under safe conditions. Guardians may contact us if they believe a minor's information has been handled improperly.

9. Changes

We may update this policy for product, legal, or operational reasons. Material changes will be announced in the app, on the website, or by other reasonable means. Where law requires separate consent, we will obtain it as required.
