Introduction
Transync (“we”, “our”, or “us”) respects your privacy and is committed to protecting your information.
This Privacy Policy explains how Transync collects, uses, and protects information when you use our browser extension.
By installing or using Transync, you agree to the practices described in this Privacy Policy.
Information We Collect
1. Translation Requests
When local AI translation is unavailable or disabled, text selected by the user may be transmitted to our servers for translation and dictionary processing.
The submitted text is processed only for the purpose of providing translation, dictionary definitions, pronunciation information, and related language features.
We do not permanently store translation content on our servers after processing is completed.
Translation requests are processed in real time and are not retained as part of a server-side translation history.
2. Local Translation History
Translation history, saved words, notes, bookmarks, preferences, and study-related data are stored locally within the user’s browser environment.
This information remains under the user’s control and is not uploaded to our servers.
Removing browser data, uninstalling the extension, or clearing local storage may delete this information.
3. Installation Analytics
To understand product usage, prevent fraud, and improve the extension, we may collect limited technical information such as when the extension is installed or removed.
This information may include:
- IP address
- Extension version
- Basic technical metadata required for analytics and operational purposes
This information is collected for internal analytics and is not sold to third parties.
4. Uninstallation Feedback
When a user uninstalls the extension, they may be redirected to a feedback page.
Any feedback, comments, feature requests, or reasons provided voluntarily by the user may be stored in our internal systems to help improve the product and user experience.
Providing feedback is optional.
How We Use Information
We use collected information to:
- Provide translation and dictionary services
- Enable pronunciation and language-learning features
- Improve extension performance and reliability
- Diagnose technical issues
- Analyze installation and uninstallation trends
- Review user feedback and prioritize improvements
- Protect the security and integrity of our services
On-Device AI Processing
Transync supports on-device AI translation capabilities provided by compatible browsers.
When on-device AI translation is enabled and available, translation processing may occur directly on the user’s device without transmitting translation content to our servers.
The availability and performance of on-device AI features depend on the browser and device environment.
Third-Party Processing
To provide translation and language-related functionality, we may use external service providers or infrastructure partners.
These providers process information solely for the purpose of delivering requested services on our behalf.
We do not sell personal information to third parties.
Data Retention
- Translation content is processed in real time and is not permanently stored after processing is completed.
- User vocabulary, notes, bookmarks, and translation history remain stored locally within the user’s browser.
- Analytics and feedback records may be retained for operational, security, and product improvement purposes.
Data Security
We implement reasonable technical and organizational measures designed to protect information against unauthorized access, disclosure, alteration, or destruction.
However, no method of electronic transmission or storage can be guaranteed to be completely secure.
Your Choices
Users may:
- Enable or disable on-device AI translation features where supported.
- Delete locally stored translation history, vocabulary, and notes through browser controls.
- Decline to submit uninstall feedback.
Changes to This Privacy Policy
We may update this Privacy Policy from time to time.
Any updates will be posted with a revised “Last updated” date.
Continued use of the extension after changes become effective constitutes acceptance of the updated Privacy Policy.
