Privacy Policy

Effective Date: August 16, 2026 · Last Updated: August 16, 2026

LOVE ORANGE TECHNOLOGY CO.,LTD ("we," "us," or "our") develops and operates the mobile application Calculator Pro (计算器专业版) (the "App"). We respect your privacy and are committed to handling your information in a transparent and responsible manner. This Privacy Policy explains how we collect, use, store, share, and protect information related to your use of the App.

By using the App, you acknowledge that you have read and understood this Privacy Policy. If you do not agree, please discontinue use of the App.

1. Scope

This Privacy Policy applies to:

This Policy does not apply to third-party websites or services that you may access via links outside the App.

2. Information We Collect

2.1 Information You Provide or Generate in the App

The App primarily stores data locally on your device. Calculations run on-device. The following data is stored on your device by default:

Data Type Purpose Storage Location
Calculation history Show recent expressions and results in the App and History widgets On-device (including the App Group used by the widget)
App settings Appearance, haptic feedback, percentage mode, favorite currencies, regional mortgage/finance options, and similar preferences On-device
Coarse display region Choose default currencies and which regional tools to show, inferred from system locale (not GPS) On-device

We do not upload the above data to our own servers. Unless you actively share content or use Apple system services (such as iCloud device backup you control), this data does not leave your device through the App.

2.2 Information Processed by Apple

App Store distribution, receipts, and related platform services are processed directly by Apple Inc. and are subject to Apple's Privacy Policy. We do not receive your Apple ID password.

2.3 Analytics Information (Firebase Analytics)

To understand feature usage and improve the product experience, the App integrates Google Firebase Analytics (using the Analytics component that does not collect the advertising identifier IDFA).

We may collect and process the following de-identified or pseudonymous usage and device-related information:

Data Type Description
Screen / feature views Events for screens such as standard calculator, scientific, convert, toolbox, and more/settings
Button activity Events such as tab selection, opening history, share, rate, and feedback
Share activity Records only the content type being shared (for example app recommend or a date-tool result) and the share channel (e.g. WeChat, LINE, Messages, copy); does not include share text or file contents
App and device technical information Such as app version, device model, OS version, language/region, and app instance identifiers, collected by the Firebase SDK under its standard mechanisms

We do not collect IDFA (Identifier for Advertisers) through the App, and we do not use the analytics data described above for cross-app advertising targeting.

This analytics data is processed by Google LLC (and its affiliates) on our behalf and is subject to the Google Privacy Policy and Firebase Data Processing and Security Terms. Google may store and process such data on its global infrastructure.

2.4 Exchange-Rate Requests

If you use the currency tool, the App may request a public rate file from our host at data.juzipie.com. The request uses ordinary network metadata (such as IP address) processed by the host and your carrier. If the request fails, the App falls back to rates bundled with the App. We do not use this request to build an advertising profile.

2.5 Feedback

When you contact us via Feedback (or a low-star rating that opens mail), the content you provide (and information your mail client may attach, such as device model, OS version, and app version) is sent to orangepie2019@gmail.com and used solely to respond to your inquiry.

2.6 Clipboard and Sharing

The App may write to the clipboard only if you copy a result, or if sending feedback email fails and the App copies our support address for you. If you use the system share sheet, the destination app you choose receives only the content you elect to share.
