Privacy Policy

FileTranslator.ai works without requiring an account. We do not maintain a centralized cloud document library or persistent personal file cabinet for users.

Document Privacy & Processing Model: For Word, Excel, PowerPoint, EPUB, TXT, and CSV documents, file parsing and reassembly occur client-side in your local browser. Original files are not uploaded to servers; only necessary text segments are transmitted for translation.

Special Notice for PDF Documents: Due to the complexity of fixed geometric coordinates, visual layer topologies, and in-place overlay redrawing, PDFs are processed within an isolated, protected sandbox. PDF files are encrypted in transit and permanently deleted immediately after translation and download delivery (ephemeral processing). We never retain files, nor do we use your documents to train AI models.

Except for ephemeral task context during processing, we do not store your original or translated documents. Files are never saved to user accounts.

In mainland China, pay with WeChat Pay. Elsewhere, use PayPal. A successful payment unlocks download in the current browser session only. A translation that does not finish is not charged.

The site may use browser local storage for device-level free quota tracking. You can clear this data in your browser at any time.

Contact support through the business contact listed on this website if you have any privacy or security questions.
