Privacy Policy
This policy explains how Translator LED (the “App”) handles your information. Our core principles: no account, no sign-in, no user profiling, no advertising.
1. What we do not collect
The App has no account system and does not collect your name, phone number, email address, contacts, location, photo library or any other information that identifies you personally. The App contains no advertising or cross-app tracking SDKs.
2. What we do process
- Anonymous device identifier: a UUID generated at random on your device the first time you launch the App. It is used to tell devices apart, count the daily free quota and verify membership. It contains no personal identity information and is regenerated if you uninstall and reinstall.
- Microphone audio: captured only while you actively hold to talk or switch Listen mode on, and streamed to Alibaba Cloud Bailian (DashScope) for speech recognition and translation. Audio is not used for training and is not kept on your device long term.
- Translation text: what you type, or what is recognised from your speech, is sent to our server (Cloudflare Workers) and forwarded to Alibaba Cloud Machine Translation / Bailian models to produce the translation and the read-aloud audio.
- Camera image: used only when you actively switch the video background on. The picture is rendered as a background on your device only; it is never uploaded or saved, and no audio is captured.
- Subscription information: when you purchase, Apple or Google generates a purchase credential (purchase token or receipt). We send it to the store's official API for verification and store the subscription status and expiry date on our server so that we can determine your entitlements. We never receive your card number or your store account password.
- Local data: translation history, presets, style settings, read-aloud and translation caches, and membership status are stored on your device. They can be removed with the system's “clear app data”, or from inside the App.
3. Why we process it, and our legal bases
- To provide the service you asked for (performance of a contract): translating, reading aloud, showing the danmaku, and verifying purchases.
- To keep the service running and prevent abuse (legitimate interests): counting the daily quota, rate limiting, and detecting automated abuse.
- With your consent: microphone and camera access, which you grant through the system prompt and can withdraw at any time in system settings.
- We do not use your audio or your translation text for advertising or for building a profile of you.
4. Sharing and international transfers
To deliver the features above we pass the necessary data to the providers listed below. We do not sell your information and we do not share it with anyone else:
- Alibaba Cloud (Bailian / DashScope, Machine Translation, speech synthesis) — speech recognition, translation and read-aloud synthesis;
- Cloudflare — server runtime and data storage;
- Apple / Google — app distribution and subscription billing verification.
These providers may process data in countries other than the one you are in. Where the law requires it, such transfers rely on appropriate safeguards, such as standard contractual clauses.
5. Permissions
Microphone and camera permissions are requested only when you actively trigger the matching feature, and only after the App has explained the purpose and you have confirmed it. You can switch them off at any time in system settings; the related feature then stops working, and nothing else is affected.
6. Security and retention
Audio and text are encrypted in transit with HTTPS / WSS. Usage and subscription records on our server are kept only for as long as necessary for the features described here. Our logs do not record your audio content.
7. Your rights
You can delete all local data by clearing the App's data. To ask for access to, or deletion of, the usage and subscription records linked to your anonymous device identifier, or to object to or restrict that processing, contact us using the details below. If you are in the EEA or the UK, you also have the right to complain to your local data protection authority. If you are a California resident, we do not sell or share your personal information as those terms are defined by the CCPA / CPRA. We answer requests within the period required by applicable law.
8. Children
The App is not directed at children. If you are a minor, please use the App only with the consent and supervision of a parent or guardian.
9. Changes to this policy
We may update this policy. The updated version takes effect when it is published on this page, and we change the date at the top at the same time.
