Datone Privacy Policy

Last updated: October 19, 2026

This Privacy Policy explains how the Datone app (called 大同互译 in Chinese; the “App”) collects, uses and protects your personal information. The App is operated by an individual developer (“we”, “us” or “our”).

1. Information We Collect

• Conversation content: the sound picked up by the microphone after you tap “Start” and before listening stops, and the text recognized from it, the translations and the languages you choose. This content is sent in real time, while listening, to the speech recognition and translation services listed in section 3; our servers only relay it and do not store it (we only record usage time and amounts).
• Account information: if you sign in with Google or Apple, the name, email address and account identifier we receive (signing in is optional).
• Information you send us: for example, problem reports you upload from the App (which may include conversation content and recordings) and your communications with us.
• Purchase information: when you buy an hour pack, we record the transaction ID, the item purchased, the time of purchase, the price and the region of purchase (such as the App Store storefront), so that we can add the time to your device or account. Payments are handled by payment services such as Apple; we do not receive your bank card or other payment details.
• Device and usage information: a device identifier, your device model, operating system version and App version, listening time, and log data such as your IP address and access times.
• Device verification information: the App uses Apple’s App Attest service to confirm that requests come from an unmodified copy of the App. We keep the resulting key identifier and public key to prevent abuse of free listening time.

2. How We Use Information

• To provide, maintain and improve the App’s services.
• To manage accounts, free time and purchased time.
• To troubleshoot problems.
• To prevent fraud and abuse and keep the service secure.
• To comply with legal obligations.

3. Disclosure of Information

We do not sell your personal information. We share it with third parties only in the following cases:

• Speech recognition and translation providers (third-party AI): to translate in real time, the conversation content described in section 1 is sent to third-party speech recognition and translation services for processing. The first time you tap “Start”, the App explains this and sends nothing until you tap “Agree and start”. They process it only on our instructions and only to provide the service.
• Cloud providers: provide us with servers, storage and network relay.
• Legal requirements: when required by law, or when necessary to protect the rights and safety of us, our users or the public.
• Business transfers: if operation of the App is transferred to someone else, related information may be transferred along with it.

4. Retention and Security

Conversation history and recordings are stored on your phone. We cannot access them unless you upload them, and you can delete them in the App at any time. We keep other information only for as long as needed to provide the service and for the purposes described in this policy. When you delete your account, we delete your account information (purchase records are kept as required by law and for financial records). To prevent free listening time from being claimed again, we keep only a value derived from your account identifier with one-way encryption, which cannot identify you, together with the time you used and redeemed.

We take reasonable measures to protect your information, but no security measure can guarantee absolute security.

5. Your Rights

Depending on the laws where you live, you may have the right to access, correct or delete your personal information, or to withdraw your consent. You can delete your account in the App’s Settings; for other requests, please email datonetranslate@gmail.com. If you don’t tap “Start”, the App sends no conversation content at all.

6. Changes to This Policy

We may update this policy and will publish the new version in the App.
