Privacy Policy

1.1 Account info: When you register, we collect your email, username, and encrypted password. 1.2 Usage data: We log your activity on the platform — translation request count, selected language pairs, features used, timestamps — to improve service quality. 1.3 Uploaded content: Uploaded images are temporarily stored to complete the translation. Original images are auto-deleted from our servers within 24 hours of processing, unless you explicitly save them to history. 1.4 Device info: We may collect browser type, OS version, IP address, and device identifiers for security verification and service optimization. 1.5 Payment info: Payments are handled by a third-party processor — we do not directly store card details. We retain only the transaction ID, order amount, and other minimum necessary payment records.

We use collected information to: • Provide, maintain, and improve the core translation service; • Manage your account, credit balance, and subscription status; • Process payments and prevent fraud; • Send service-related notifications such as billing reminders and feature updates (you can unsubscribe anytime); • Analyze aggregate usage statistics to improve the product; • Respond to your support or technical requests; • Comply with applicable laws and regulations.

We do not sell your personal information to any third party. We may share your info in these cases: 3.1 Service providers: We share necessary info with trusted partners providing cloud storage, payment processing, and analytics — bound by strict data protection agreements. 3.2 AI model services: Translation may be processed via third-party AI services (e.g., OpenAI, Google Cloud); uploaded image content may be transmitted to these services and is subject to their privacy policies. 3.3 Legal requirements: We may disclose information in response to laws, court orders, or lawful government requests. 3.4 Business transfers: In a merger, acquisition, or asset sale, user data may transfer as part of the assets — we will notify you in advance.

4.1 We use industry-standard encryption (TLS/SSL) for data in transit and encrypt sensitive data at rest. 4.2 We perform regular security audits and limit internal employee access to user data (principle of least privilege). 4.3 While we take reasonable security measures, no Internet transmission or electronic storage method can be 100% secure. We will notify affected users promptly in the event of a security incident, in accordance with applicable law.

5.1 We use cookies and similar technologies to keep you signed in, remember preferences, and analyze usage patterns. 5.2 Types of cookies we use: • Essential cookies: required for core functionality, cannot be disabled; • Analytics cookies: help us understand user behavior to improve the service (optional); • Preference cookies: remember your language and UI settings (optional). 5.3 You can manage or disable cookies in your browser settings, but doing so may affect some features.

• Account data: retained until you delete your account; • Translation history: retained per your settings, up to 12 months; • Temporary uploaded images: deleted within 24 hours of processing; • Payment records: retained for 7 years per financial regulations; • Log data: typically auto-purged after 90 days.

Under applicable data protection laws, you have these rights: • Access: request a copy of personal info we hold about you; • Rectification: request correction of inaccurate personal info; • Erasure: request deletion of your account and associated data; • Portability: request export of your data in a structured format; • Object: object to certain processing such as marketing emails. To exercise these rights, email [email protected] — we will respond within 30 days.

The Service is not directed to children under 13. If we discover we have inadvertently collected info from a child, we will delete it promptly. If you believe we may have collected such information, please contact us immediately.

Our servers may be located outside mainland China (including the US, Singapore, etc.). Your data may be transferred to these regions for processing. We take appropriate safeguards to ensure such transfers comply with applicable law.

We may update this Privacy Policy from time to time. For material changes, we will notify you via email or a prominent notice on the site, and update the "Last updated" date at the top. We recommend reviewing this page periodically.
