Privacy Policy

1. Information We Collect

We may collect the following categories of information:

• Device information, such as device model, operating system version, app version, language, time zone, and general diagnostic information.
• Usage information, such as feature interactions (e.g., bend types used, calculation preferences), app performance data, analytics events, and crash logs.
• Purchase information related to Apple In-App Purchases and auto-renewable subscriptions, such as product type, subscription status, and purchase confirmation.
• Sensor data from the device's accelerometer and gyroscope, accessed solely when you use the spirit level feature to measure angles and level surfaces.
• Support information that you voluntarily provide when contacting us by email.

2. Permissions We Request

To provide core features, the App may request the following permissions:

• Motion & Orientation Sensors: to enable the spirit level feature for measuring conduit angles and surface leveling.

You may deny or revoke these permissions at any time in your device settings. If you do so, the corresponding features of the App may not function properly.

3. How We Use Information

We use information for the following purposes:

• To provide conduit bending calculations, spirit level measurements, and calculation history features.
• To operate, maintain, improve, and troubleshoot the App.
• To monitor app stability, diagnose crashes, and analyze usage trends.
• To verify, activate, restore, and manage in-app purchases and subscriptions.
• To respond to support requests and user inquiries.
• To comply with legal obligations and enforce our rights.

4. Calculation Data and Sensor Access

The App performs conduit bending calculations entirely on your device. Input values such as offset distance, bend angle, rise, run, and conduit size are processed locally and are not transmitted to our servers unless used for anonymized analytics.

When you use the spirit level feature, the App accesses your device's accelerometer and gyroscope in real-time to display angle and level measurements. This sensor data is processed locally on your device and is not collected or stored by us.

5. Firebase

We use Firebase, a service provided by Google, to support analytics, diagnostics, crash reporting, and related app functionality. Firebase may collect certain device identifiers, usage data, and diagnostic information in accordance with Google's policies.

For more information, please review Google's Privacy Policy:

6. In-App Purchases and Auto-Renewable Subscriptions

The App may offer premium features through in-app purchases and auto-renewable subscriptions via Apple's App Store. Payments are processed by Apple, not by us directly. We do not collect or store your full payment card or billing information.

We may receive limited transaction information from Apple, such as purchase confirmation, product identifier, and subscription status, in order to activate, manage, and restore premium access.

Subscriptions renew automatically unless canceled in your Apple ID account settings at least 24 hours before the end of the current billing period. Refund requests are handled by Apple in accordance with Apple's policies.

7. Sharing of Information

We do not sell your personal information. We may share limited information only in the following circumstances:

• With service providers such as Firebase, solely to help us operate, analyze, and improve the App.
• When required by law, regulation, legal process, or governmental request.
• To protect the rights, safety, and property of users, the public, or our services.
• In connection with a merger, acquisition, financing, reorganization, or sale of assets, subject to applicable legal requirements.
