Price Translator Privacy Policy

Effective Date: July 23, 2025
Developer/Operator: Changsha QuickWis Network Technology Co., Ltd. (hereinafter referred to as “the Company”)

Article 1: Agreement Confirmation and Acceptance

1.1 You must carefully read this Privacy Policy before using the service. By checking “Agree” or actually using the service, you are deemed to have fully understood and accepted all terms herein.
1.2 Minors (<18 years old) must understand this Policy under guardian guidance. Service is prohibited for users under 14 years old.

Article 2: Data Collection & Storage Principles

2.1 No-Account & Zero-Upload Design

  • This service requires no registration or login, and collects no personally identifiable information (e.g., phone numbers, ID cards, email addresses).
  • All data (including exchange rate preferences, query history, etc.) is stored exclusively on your local device and never transmitted to servers.Sole exception: To restore membership benefits (e.g., purchase recovery) when switching devices, your account information and device identifiers will be encrypted and backed up to our servers.

2.2 Minimal & Necessary Scope

  • Essential functional data:
    • Your selected region of residence, target region, and currency preferences (e.g., CNY/USD)
  • Optional authorized data:
    • Location permissions (foreground-only access; used to auto-suggest destination currencies; disabling doesn’t affect core functionality)
  • Automatically collected data:
    • Device model and OS version (solely for troubleshooting desktop widget/Apple Watch compatibility)
