Privacy Policy for HardTools

Last Updated: November 11, 2026

HardTools (“the App”), developed by JanabiSoft (“we,” “us,” or “our”), is designed as an offline-first utility kit and sensor diagnostics engine. We respect your privacy and are committed to protecting it through compliance with this Privacy Policy.

1. Information We Collect and Third-Party SDKs

HardTools operates with an offline-first architecture for all core measuring and diagnostic functions. We do not collect or store personal identifiers like your name, email address, or phone number on our servers.

To maintain the application, analyze usage patterns, and provide localized advertisements for free users, we integrate third-party software development kits (SDKs):

A. Google AdMob (Advertising)

  • Purpose: Displays banner advertisements to free tier users.
  • Data Processed: Device identifiers (e.g., Advertising ID), approximate IP address, interaction data, and diagnostic data related to ad performance.
  • Pro Tier: Users who upgrade to HardTools Pro experience a 100% ad-free interface, which completely disables AdMob banner requests.

B. Google Firebase Analytics & Crashlytics (Analytics & Stability)

  • Purpose: Helps us understand how the app is used, monitor app health, track crashes, and improve overall performance across mobile platforms.
  • Data Processed:
    • Firebase Analytics: App usage metrics, feature interactions, launch frequency, and general device info (device model, OS version).
    • Crashlytics: Crash logs, stack traces, and system state at the time of an application error.

C. Aptabase (Privacy-First Telemetry & Analytics)

  • Purpose: Provides lightweight, privacy-focused analytics to track feature usage trends without profiling individual users.
  • Data Processed: Anonymous usage events and aggregated technical metrics. Aptabase does not track personal data across apps or websites.

2. Hardware Permissions & Device Sensors

HardTools requires access to specific hardware sensors to perform spatial measurements, orientation tracking, acoustic analysis, and illumination. All sensor data is processed locally on your device in real time and is never transmitted to our servers or external third parties.

  • Camera & LiDAR Sensor: Used exclusively for spatial tracking, 3D AR measurements, surface detection, and distance calculations.
  • Microphone Array: Used exclusively to compute Sound Pressure Levels (SPL), dBA/dBC acoustic curves, and peak decibel meters[. Audio is analyzed in real-time memory and is never recorded or saved as audio files.
  • Location Services (GPS): Used to calculate True North references, magnetic declination models, and GPS position fixes (latitude/longitude/altitude) inside the compass module[.
  • Magnetometer & Motion Sensors (IMU): Used for heading direction, azimuth, inclinometer tilt alignment, and haptic feedback triggers[.
  • Flashlight (LED): Used for high-lumens illumination and strobe/SOS patterns.

3. Local Data Storage

All saved capture logs, measurement records, compass bearings, and custom preferences are stored locally on your device using encrypted, high-performance key-value storage (hive_ce). Uninstalling the app or clearing local app data will permanently erase your locally stored session logs unless you explicitly export them (e.g., via CAD/CSV export).

4. In-App Purchases & Entitlements

We use RevenueCat to manage in-app purchases and verify entitlement status for HardTools Pro. RevenueCat processes purchase tokens generated by the Google Play Store or Apple App Store to validate transaction status. We do not store or process payment card details directly.

For more information on how our third-party service providers collect and process data, please refer to their respective privacy policies:

6. Children’s Privacy

HardTools does not knowingly collect or solicit personal information from children under the age of 13. If you believe a child has provided us with personal information through third-party analytics, please contact us so we can take immediate corrective measures.

7. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. Any changes will be posted on this page with an updated “Last Updated” date.
