Privacy Policy

We collect the minimum information needed to provide the Service: • Account information: when you sign in with Google, we receive basic profile data (name, email address, and profile picture). • Documents you upload: the content of the files you submit for translation. • Usage data: basic technical information such as pages translated and credits used, for billing and service operation. We do not sell your personal information, and we do not use it for advertising.

We use the information we collect solely to: • Provide and operate the translation Service; • Authenticate your account and apply your credit balance; • Process and deliver your translations; • Communicate with you about your account or support requests.

Translations are generated by third-party AI models, not by human translators. To produce a translation, the content of your document is transmitted to these providers for processing. • Paid-plan users: content is processed through our providers' premium AI infrastructure, under which your content is NOT used to train or improve AI models. • Free-plan users: content may be used by the third-party AI provider to improve their services. For maximum confidentiality when handling sensitive documents, we recommend using a paid plan. Any processing of content by third-party AI providers is governed by their respective terms of service and privacy policies.

Your documents and translations are processed transiently in server memory solely to generate the translation, and are not permanently stored on our systems once translation is complete. The only exception is content you explicitly choose to submit to us — for example, a file attached to a bug report — which we retain only as long as needed to resolve the issue. Account information is retained for as long as your account remains active.

We apply reasonable technical and organizational measures to protect your information against unauthorized access, disclosure, or loss. Data is transmitted over encrypted connections (HTTPS). Still, as with any online service, no system can guarantee absolute security against every risk.

Depending on your jurisdiction, you may have the right to access, correct, or delete your personal information, and to object to or restrict certain processing. To exercise these rights, or to delete your account and associated data, please contact us by email at support@zentrans.app or using the support options available in the application.

We use essential cookies and similar technologies only to keep you signed in and to operate the Service. We do not use third-party advertising or tracking cookies.

Payments for credits are handled by our Merchant of Record, Paddle.com (Paddle.com Market Ltd), not by us. When you make a purchase, your payment details (such as card information and billing address) are collected and processed directly by Paddle under Paddle's own Privacy Policy. We do not receive or store your full payment card details — we only receive confirmation of payment and the limited transaction information needed to apply your credits.

We may update this Privacy Policy from time to time. Material changes will be posted on this page with an updated "Last updated" date. Your continued use of the Service after changes are posted constitutes acceptance of the revised policy. If you have any questions about this Privacy Policy or how your data is handled, please contact us at support@zentrans.app or through the support options available in the application.
