Privacy Policy

We may also collect limited technical information such as browser or device context, extension settings, diagnostic logs, and feature usage events where needed to operate, secure, or improve the product.

• To provide translation, grammar breakdown, pronunciation, flashcards, and account features.
• To preserve saved vocabulary, study progress, and settings across sessions.
• To authenticate users and manage subscriptions or premium access.
• To maintain reliability, reduce abuse, debug failures, and improve product quality.
• To send important product, billing, or account notices where appropriate.

When you choose to translate text, generate a grammar explanation, or use related language features, Renshi sends the specific content required for that request to trusted third-party processing providers.

We design these flows to send only the content needed for the task. We do not intentionally send your password, payment credentials, or unrelated private account details as part of language-processing requests.

We use third-party infrastructure providers to operate Renshi. Depending on the feature, those providers may include authentication, hosting, database, payment, analytics, and AI-processing services.

• Authentication and account infrastructure.
• Cloud hosting and storage.
• Payment or subscription processing.
• Language model and speech services used to fulfil requested study features.

We may disclose personal information to service providers helping us operate the product, where disclosure is required or authorised by law, where needed to protect users or maintain security, or as part of a business transfer or restructuring.

We do not sell personal information as part of our ordinary business model.

We take reasonable technical and organisational steps to protect personal information from misuse, loss, and unauthorised access, modification, or disclosure.

We keep information only for as long as reasonably required to provide the product, meet legal or operational requirements, resolve disputes, and maintain business records. When information is no longer needed, we aim to delete it or de-identify it where practical.

If you want to access, update, or correct personal information we hold about you, you may contact us using the support details published with the product. We may need to verify your identity before actioning a request.

If you believe information we hold is inaccurate, incomplete, or out of date, please let us know and we will take reasonable steps to correct it.
