Effective Date: September 13, 2026
Last Updated: September 14, 2026
Developer: Xi'an Yunjian Xingyu Technology Co., Ltd. (西安云间星语科技有限公司)

Introduction

Welcome to AltitudeNow!

This Privacy Policy applies to the AltitudeNow app and related services you use (the "App"). The developer of the App is Xi'an Yunjian Xingyu Technology Co., Ltd. (西安云间星语科技有限公司). The App is distributed through Huawei AppGallery, runs on HarmonyOS NEXT, and may use system and platform capabilities such as Location Kit, Map Kit, Camera Kit, and IAP Kit.

We understand that your privacy matters. We are committed to handling your information in a transparent and restrained manner, and to keeping your data on your device whenever possible. This Privacy Policy is designed to help you understand:

• What information we collect
• How we use that information
• Your control over your information
• How we protect your information

Please read this Privacy Policy carefully. By downloading, installing, or using the App, you agree to the practices described in this policy.

1. Information We Collect

1.1 Information We Collect or Process

AltitudeNow processes data on a "local-first, minimum necessary" basis. We may collect or process the following information:

1.1.1 Information You Provide or That Is Generated Through Use

• Location and altitude information: After you grant location permission (including precise location and, where needed, approximate location), we use Location Kit to read your device's GPS coordinates, altitude, vertical accuracy, heading (for the compass), and related data to display real-time altitude, resolve place names, generate summit/track cards, record track routes, and display the Summit Passport
• Track route data: When you use track recording, we continuously record GPS coordinate sequences, distance, duration, speed, and other activity metrics, and save route JSON files locally; while track recording is in progress, and after you authorize background location, the App may continue to obtain location updates (which may be accompanied by a system notification or ongoing-task indicator)
• Photos and images: When you use the summit camera (Camera Kit) or mark an arrival with a one-tap theme background Pin, the App captures or generates images; summit cards and track cards may include your photos plus overlaid text and graphics
• Arrival record data: Including capture or save time, altitude, latitude and longitude, place text, selected template, activity metrics (such as distance, elevation gain, and duration), and local image file paths
• Track record data: Including end time, start/end/route coordinates, distance, duration, average speed, end-point altitude, card image path, route file path, sport type (hike/run/ride), and template identifier
• Summit Passport data: Visit point information (coordinates, source type, etc.) aggregated on your device from local arrival and track records for map Pin display; this data is derived from on-device records and is not uploaded to our servers
• App settings: Such as altitude units (meters/feet), track distance units, language preference, haptic feedback toggle, map theme, summit theme colors, and other preferences stored on your device
• Free quota counters: To enforce free-tier limits (such as summit capture counts and track recording counts), the App stores related usage counters on your device

1.1.2 Automatically Collected Information

• Device and sensor information: On supported devices, the barometer reads pressure and estimates oxygen-related data for on-screen display or card/weather ambience; the compass reads device orientation sensor data; the above data is processed locally and is not uploaded to our servers by default
• Device information: To keep the App running properly, we may obtain basic technical information through system interfaces such as device model, operating system version, app version, and language/region settings (for compatibility checks, version update detection, and bug fixes, and not to identify a specific natural person)
• Version update detection information: The App may send app identifier information to public AppGallery query interfaces to obtain the latest version number and determine whether an update prompt is needed; this process does not involve your personal identity or business data
• Subscription entitlement status: When you purchase Pro membership, Huawei AppGallery verifies transactions and subscription status through IAP Kit; we only read verification results locally on your device to unlock features and do not collect or store your payment card numbers or other financial information ourselves

1.1.3 Information Processed Over the Network (Not Stored on Our Servers by Default)

In the following scenarios, some data may leave your device, but we do not use it to build user profiles on our own servers or to store your personal movement history long term:

• Reverse geocoding: To convert coordinates into place names, latitude and longitude may be sent to geocoding capabilities provided by Location Kit or Huawei/system services; this processing is governed by the relevant service provider's privacy policy
• Weather queries: Weather conditions are obtained through third-party weather data services such as Open-Meteo (this App does not use Apple WeatherKit); requests are initiated directly by your device, typically containing only approximate latitude and longitude and necessary query parameters, and we do not retain those requests on our servers
• Map services: Track maps, Summit Passport, and related features use Huawei Map Kit; during map loading your device may communicate with Map Kit services (such as map tile requests), which may involve approximate location information

1.2 Information We Do Not Collect

Except when you contact us directly, we do not proactively collect the following:

• Your name, national ID number, bank account details, or other strong identity identifiers
• Your contacts, SMS messages, or call logs
• Your Huawei ID password or other account credentials
• Advertising identifiers used for cross-app tracking (this App is not designed for ad tracking)
• Continuous background location when you are not using related features (the App may continue location updates in the background only while track recording is in progress and after you authorize background location; otherwise it primarily uses "While Using the App" location)
• Unified accounts or cloud business data backups (the current version requires no registration, and data is stored independently on your device by default)

2. How We Use Information

2.1 How We Use Your Information

Information we collect or process is used only for the following purposes:

2.1.1 Providing Core Features

• Real-time altitude and place display: Using location and altitude data to show your current status on the summit screen
• Compass: Displaying bearing, latitude and longitude, and current altitude
• Summit camera and card generation: Combining photos or theme backgrounds with altitude, place, pressure, time, and other information into shareable cards (the free tier may include a watermark; Pro can remove it)
• Track recording and track cards: Recording routes, calculating distance/speed/duration, and generating shareable cards with route snapshots
• Arrival records and track records: Saving, displaying, and managing your historical records locally on your device
• Summit Passport (Pro): Aggregating and displaying Pins for places you have visited on your device
• Export and sharing: Saving cards to the system photo library/media library when authorized, or letting you choose recipients through the system share sheet
• Settings and units: Remembering your units, language, and related preferences
• Pro membership benefits: Unlocking corresponding features based on Huawei IAP verification results

2.1.2 Improving the App Experience

• Performance optimization: Analyzing necessary diagnostic and version information to improve stability
• Feature improvement: Understanding feature usage (if anonymous analytics or crash services are integrated in the future, this policy will be updated accordingly)
• Bug fixes: Collecting necessary diagnostic information to resolve defects quickly
• Version update prompts: Comparing AppGallery version numbers and prompting you to update when appropriate

2.2 How We Will Not Use Your Information

We promise that we will not:

• Sell, rent, or trade your personal information to third parties
• Use your arrival records, tracks, or photos for unauthorized advertising
• Share personally identifiable information with other companies or organizations (except as required by law or with your explicit consent)
• Use your data for purposes not described in this policy without notice

3. Information Storage

3.1 Local Storage

AltitudeNow uses a local-first data storage strategy:

• Arrival records, track records, and related metadata are stored in the App's private database on your device
• Summit/track card images are saved in the app sandbox/private storage and/or in the system photo library if you choose to save them there
• Track route files are saved in app-private directories in formats such as JSON
• Settings, cache, and free quota counters (such as recent geocoding results) are stored on your device
• Our servers do not store your arrival records, tracks, photos, or complete location history by default

3.2 System Backup (Optional, Controlled by the System)

If you enable device system backup (such as Huawei account cloud backup or manufacturer backup), data in the app-private directory may be included in the corresponding cloud backup service and is governed by that provider's policy. We do not operate a separate cloud business database; such backups are managed by you and your operating system provider.

3.3 Cross-Device Sync

The current version does not provide iCloud / CloudKit or cross-device cloud sync. Your summit and track records remain on this device by default.

3.4 Data Retention

• Local data: Remains on your device until you delete records or uninstall the App
• Deleting data: When you delete a record, we also delete associated local images and route files; uninstalling the App removes data in the app sandbox/private directory (images already saved to the photo library must be managed by you in Photos)
• No default server backup: Because we do not store your business data on our servers by default, there is generally no server-side retention period on our side

4. Information Sharing

4.1 We Do Not Proactively Share Your Business Data

Except as otherwise stated in this policy, we will not sell or proactively provide your arrival records, tracks, photos, or complete location history to third parties.

4.2 Third-Party Services

To provide certain features, your device may interact directly with the services below. These services have their own privacy policies:

4.2.1 Huawei / HarmonyOS System and Kit Services

• Location Kit
  • Purpose: Obtain GPS altitude, coordinates, heading, and location permission status; background location updates may be enabled while track recording is in progress (such as `LOCATION_IN_BACKGROUND`; exact permission names follow the system)
  • Data processing: Processed locally on your device after authorization; reverse geocoding and similar requests may be handled by Huawei-related services
  • Your control: You can manage location permissions (including background location) for this App in system Settings

• Map Kit
  • Purpose: Track maps, Summit Passport map display, route visualization, and map snapshots
  • Data processing: Map tiles and related requests are handled by Huawei Map Kit services and may involve approximate location information
  • Details: Please see the Huawei Consumer Business Privacy Statement

• Camera Kit
  • Purpose: Capture background photos for the summit camera; theme Pin mode may not require the camera
  • Data processing: Images are processed locally to generate cards; they are not automatically uploaded to our servers without your action
  • Your control: You can revoke camera permission in system settings at any time

• Media library / photo library write access
  • Purpose: Save generated summit/track cards to the system photo library or media library
  • Data processing: Files are written directly to your device; the first save may require a dynamic permission request
  • Your control: You can revoke related media write permissions at any time

• Sensor services (barometer / orientation, etc.)
  • Purpose: Read pressure, compass direction, and related data on supported devices
  • Data processing: Processed locally on the device; related UI is hidden on devices without a barometer

• Background location and notifications / ongoing tasks
  • Purpose: Maintain continuous location while track recording is in progress and possibly show a recording-status indicator
  • Data processing: Indicator content is used only to show recording status and does not include your full track details; background location stops immediately when recording ends

• IAP Kit (In-App Purchases)
  • Purpose: Purchase, verification, restoration, and delivery confirmation of Pro membership subscriptions and lifetime unlocks
  • Data processing: Payment and subscription management are handled by Huawei; we only receive verified entitlement status and do not collect your payment card numbers or other financial information
  • Note: Pro benefits are verified and restored based on the app store account and purchase channel used for the purchase

• Geocoding
  • Purpose: Convert coordinates into readable place names
  • Data processing: Prefer reverse geocoding from Location Kit / system capabilities; when unavailable, the App may fall back to displaying coordinate strings

4.2.2 Third-Party Weather Data (Open-Meteo)

• Purpose: Obtain weather codes and related information based on your approximate current location for on-screen or card display
• Data processing: Your device sends HTTPS requests to Open-Meteo, typically containing only latitude, longitude, and necessary query parameters; we do not operate this service and recommend reviewing Open-Meteo's documentation
• Note: When the network is unavailable, the App may fall back to local rules for display without sending requests; Settings attributes weather data to Open-Meteo

4.2.3 App Store Services

• Huawei AppGallery / AppGallery Connect
  • Purpose: App distribution, version update queries, in-app purchases, and subscription management
  • Data processing: Handled by Huawei under its privacy policy

4.2.4 Sharing You Initiate

When you use the system Share feature, the destination apps you choose will handle the shared content under their own privacy policies. Sharing is initiated by you, and we are not responsible for how third-party apps process your data.

4.3 Legal Requirements

In rare cases, we may be required to disclose information:

• To comply with laws, regulations, legal processes, or government requests
• To protect our rights, property, or safety
• To prevent fraud or security threats
• To protect the lawful rights and interests of users or the public

Because we do not store your business data on our servers by default, we usually cannot provide data that has been deleted from your device or was never uploaded, even if we receive such a request; we will still cooperate within the scope permitted by law.

5. Data Security

5.1 Security Measures

We take the following measures to protect your information:

• Local encryption and sandboxing: Relying on HarmonyOS data protection mechanisms, app data is stored in private spaces where other apps cannot access it directly
• Minimum permissions: Requesting only necessary permissions such as location, camera, photo library/media, and network when related features are used; background location is requested only when you start track recording
• No upload by default: Arrival records, tracks, and photos remain on your device by default and are not routed through our servers
• Secure development practices: Following Huawei / HarmonyOS security recommendations and addressing known issues promptly

5.2 Your Responsibilities

To help protect your data, we recommend that you:

• Set a passcode or use biometric unlock on your device
• Do not share an unlocked device with others
• Keep your operating system updated to receive security patches
• Grant app permissions carefully and review this App's permission list regularly in system Settings
• Before sharing cards in public, confirm whether they contain precise coordinates or place information you do not want to disclose

5.3 Data Breach Notification

Although we take reasonable measures, no system is completely secure. If a data security incident involving systems under our control occurs, we will:

• Investigate promptly and take remedial action
• Notify affected users within a reasonable time, where applicable
• Report to relevant regulators if required by law

6. Your Rights

6.1 Access and Control Over Your Data

You have control over your data:

• View data: Review historical data in Arrival Records, Track Records, and Summit Passport

6.2 Revoking Permissions

You can revoke app permissions at any time in your device system settings. You can usually find AltitudeNow in Settings and manage location (including background location), camera, photo library/media, notifications, and related permissions. Track recording may require separate authorization for background location. Revoking permissions may make related features unavailable or degraded (for example, without location permission, real-time altitude or track recording cannot work).

6.3 Deleting Account and Data

This App does not require account registration. You can delete data by:

• Deleting records: Deleting individual or all arrival/track records in the App
• Deleting the App: Uninstalling the App removes data in the app-private directory
• Photo library content: Images saved to the system photo library must be deleted in the Photos app
• Subscription management: Pro membership subscriptions can be canceled in your Huawei ID / AppGallery subscription settings; entitlement restoration is based on verification results from that purchase channel

7. Children's Privacy

AltitudeNow is intended for general users. We do not knowingly collect personal information from children under 13.

If you are a parent or guardian and believe your child has provided us with personal information without your consent, please contact us and we will take steps to delete the relevant information.

8. Regions and Scope

This App is distributed through Huawei AppGallery (actual availability depends on regional policies and Map Kit / IAP availability). If you use this App outside mainland China:

• Your business data is stored locally on your device by default
• If system backup is enabled, data storage location depends on your account region and the relevant provider's service layout
• Map Kit, IAP, and other Huawei services may be unavailable in some regions; related features may be hidden or degraded when unavailable
• We strive to follow core principles of applicable data protection laws (such as GDPR and CCPA); specific rights may vary by local law
