PRIVACY POLICY FOR GPS LAND AREA MEASURE

Last Updated: September 8, 2026

Effective Date: September 8, 2026


Welcome to GPS Land Area Measure ("we," "our," "us," or the "App"), developed 

and operated by GPS Land Area Measure Team ("Developer"). We are deeply committed 

to protecting your privacy and ensuring you have complete visibility and control 

over your data.


This Privacy Policy explains how our iOS application collects, uses, stores, 

and protects information when you download, install, and use GPS Land Area 

Measure (including any related features, services, and export capabilities).


By installing or using GPS Land Area Measure, you consent to the practices 

described in this Privacy Policy. If you do not agree with this policy, please 

uninstall and discontinue using the application.



--------------------------------------------------------------------------------

1. SUMMARY OF CORE PRIVACY PRINCIPLES

--------------------------------------------------------------------------------


- On-Device Data Processing: All geospatial surveys, coordinates, perimeter 

  calculations, area measurements, notes, and custom titles are processed and 

  stored locally on your device via Apple's SwiftData framework.

- No Server Storage of Survey Data: We do not operate external cloud servers 

  that store, ingest, sell, or analyze your private land boundary measurements.

- Transparent Permissions: Location and motion/compass access are requested 

  strictly for real-time measurement functionality while using the App.

- User Control: You retain full ownership and control over your survey records 

  and can delete them at any time.



--------------------------------------------------------------------------------

2. INFORMATION WE COLLECT AND HOW WE USE IT

--------------------------------------------------------------------------------


A. Location Data (CoreLocation)

- What We Access: When granted permission ("While Using the App"), the App 

  accesses your device's GPS hardware, latitude, longitude, altitude, horizontal 

  accuracy, and course data.

- Purpose:

  1. To show your live position on the map interface.

  2. To record GPS waypoints when using the "Walk / GPS Live Tracking" 

     measurement mode.

  3. To calculate real-time geodesic distances and land areas between placed 

     boundary markers.

  4. To calibrate compass heading telemetry.

- Retention & Transmission: Location coordinates are processed strictly in 

  real-time on your device and saved into your local SwiftData database only when 

  you explicitly save a survey. Location data is NEVER sent to our servers or 

  tracked in the background.


B. Compass & Motion Telemetry (CoreMotion / CoreLocation Heading)

- What We Access: Real-time magnetic heading and true heading sensor data.

- Purpose: To orient the map display and provide real-time compass navigation 

  relative to your field measurement pins.

- Retention: This data is ephemeral and is not stored or transmitted.


C. Local Survey Content (SwiftData & File System)

- What Is Stored: Custom survey titles, polygon/polyline coordinates, area 

  calculations (e.g., acres, hectares, sq. meters, sq. feet), perimeter 

  distances, notes, timestamps, elevation statistics, and map snapshot 

  thumbnails.

- Storage Location: Exclusively stored within your device's secure local app 

  sandbox using Apple's SwiftData framework.

- Exporting Data: When you export surveys as PDF documents, CSV coordinate 

  tables, PNG images, KML, or GeoJSON files, these files are generated on-device 

  and shared exclusively via Apple's native iOS Share Sheet 

  (UIActivityViewController).


D. Subscriptions & In-App Purchases (StoreKit & RevenueCat)

- Service Provider: RevenueCat, Inc. and Apple App Store.

- What Is Processed: When you purchase or restore a premium subscription, Apple 

  securely handles transaction processing and billing. RevenueCat processes 

  anonymous app user identifiers and StoreKit receipt tokens to validate active 

  entitlements (e.g., ad-free experience, unlimited exports).

- Payment Information: We do NOT collect, process, or store your credit card 

  numbers, banking details, or billing addresses. All financial transactions 

  are managed securely by Apple Inc.


E. Advertising & Tracking (Google AdMob & User Messaging Platform)

- Service Provider: Google Mobile Ads (AdMob) and Google User Messaging 

  Platform (UMP).

- Data Collected by Third Parties: For users on the free version of the App, 

  Google AdMob may collect and process device identifiers (such as IDFA, where 

  permitted by iOS App Tracking Transparency), coarse location, IP address, and 

  app usage diagnostics to serve banner, interstitial, native, or app open 

  advertisements.

- Consent Management: In regions subject to the General Data Protection 

  Regulation (GDPR) / UK GDPR or California privacy laws, the Google UMP consent 

  dialogue is presented to allow you to customize, grant, or revoke consent for 

  personalized ads and cookies.

- Opting Out / Ad-Free Option: You can upgrade to our Premium Subscription to 

  remove all third-party advertisements completely. You can also adjust ad 

  tracking settings in iOS under Settings > Privacy & Security > Tracking.


F. App Configuration & Diagnostics (Firebase Remote Config)

- Service Provider: Google Firebase Remote Config.

- Purpose: We use Firebase Remote Config to dynamically fetch non-identifying 

  operational parameters (such as feature flags, default unit settings, and ad 

  frequency rules).

- Data Collected: Anonymous device characteristics (e.g., OS version, device 

  model, app version) without collecting personal identities.



--------------------------------------------------------------------------------

3. THIRD-PARTY SERVICES AND SDKS

--------------------------------------------------------------------------------


We work with trusted third-party SDK providers who may collect non-personal 

information subject to their independent privacy policies:


1. Apple MapKit & CoreLocation

   - Purpose: Map rendering, satellite imagery, GPS telemetry

   - Privacy Policy: https://www.apple.com/legal/privacy/


2. Google AdMob & UMP

   - Purpose: In-app advertising and privacy consent

   - Privacy Policy: https://policies.google.com/privacy


3. Google Firebase Remote Config

   - Purpose: Remote configuration and operational flags

   - Privacy Policy: https://firebase.google.com/support/privacy


4. RevenueCat

   - Purpose: Subscription entitlement verification

   - Privacy Policy: https://www.revenuecat.com/privacy



--------------------------------------------------------------------------------

4. HOW YOUR DATA IS STORED AND PROTECTED

--------------------------------------------------------------------------------


1. On-Device Encryption: Your saved survey history is stored within your device's 

   sandboxed local storage protected by iOS hardware-level Data Protection 

   encryption.

2. No Account Required: You do not need to register, create a profile, or submit 

   your email address to use GPS Land Area Measure.

3. Data Loss & Backups: Because your measurements are stored locally, surveys 

   are included in your personal encrypted iCloud/iTunes device backups if you 

   have iOS backups enabled. Uninstalling the App without a backup will delete 

   locally saved surveys.



--------------------------------------------------------------------------------

5. USER RIGHTS AND DATA MANAGEMENT

--------------------------------------------------------------------------------


Depending on your jurisdiction (including the EU/EEA under GDPR, the UK under 

UK GDPR, and California under CCPA/CPRA), you have specific privacy rights:


- Access & Portability: You can export all your coordinates and survey data at 

  any time in standard formats (CSV, PDF, PNG, KML/GeoJSON).

- Deletion & Erasure: You can delete individual surveys inside the App's History 

  tab at any time, or permanently erase all app data by uninstalling the App 

  from your device.

- Withdrawal of Consent:

  * Location Permissions: You can disable or modify GPS permissions at any 

    time via iOS Settings > GPS Land Area Measure > Location.

  * Ad Consent: You can reconfigure ad consent at any time through the in-app 

    Settings menu ("Privacy Consent Options") or via iOS Settings > Privacy & 

    Security > Tracking.



--------------------------------------------------------------------------------

6. CHILDREN'S PRIVACY (COPPA & GDPR COMPLIANCE)

--------------------------------------------------------------------------------


GPS Land Area Measure is not directed to children under the age of 13 (or under 

16 in the EU/EEA). We do not knowingly collect or solicit personal information 

from children. If we become aware that personal information has been collected 

from a child without verified parental consent, we will take immediate steps to 

delete such data.



--------------------------------------------------------------------------------

7. CALIFORNIA PRIVACY RIGHTS (CCPA / CPRA)

--------------------------------------------------------------------------------


Under the California Consumer Privacy Act (CCPA) and California Privacy Rights 

Act (CPRA), California residents have the right to:

1. Know what personal information is collected, disclosed, or sold.

2. Request deletion of their personal information.

3. Opt-out of the "sale" or "sharing" of personal information for cross-context 

   behavioral advertising.


We do not sell personal data or survey records. Third-party ad networks (Google 

AdMob) may collect device identifiers for advertising purposes if permitted by 

your iOS tracking settings. You may exercise your right to limit ad tracking in 

your iOS settings or via the in-app privacy consent settings.



--------------------------------------------------------------------------------

8. CHANGES TO THIS PRIVACY POLICY

--------------------------------------------------------------------------------


We may update our Privacy Policy periodically to reflect new features, 

operational practices, or legal requirements. When updates occur:

- The "Last Updated" and "Effective Date" at the top will be revised.

- Material changes will be communicated through an in-app notice or updated 

  App Store release notes.


Your continued use of GPS Land Area Measure after changes are posted constitutes 

your acceptance of the revised Privacy Policy.



--------------------------------------------------------------------------------

9. CONTACT AND INQUIRIES

--------------------------------------------------------------------------------


If you have any questions, concerns, or requests regarding this Privacy Policy 

or your data, please contact us email.
