Privacy Policy隐私政策

This Privacy Policy explains how Chuyi (the "Extension") and the website at translate.chuyi.ai (together, the "Service") handle information. Chuyi is operated by an individual sole proprietor based in Saskatchewan, Canada ("Chuyi", "we", "us"). You can contact us by email at hi@translate.chuyi.ai. We will update this page with our company entity name once business registration is complete.

1. Information the Extension processes

a) Chat message text (to translate it)

On supported web chat sites only, the Extension reads the text of messages displayed on the page and the text you type into the message box, so it can translate them. The Extension does not read content on other websites. It does not read your contact lists, files, images, or passwords, and it does not access voice audio unless you turn on the upcoming Voice feature (see section 1(f)). Message text is used only to provide translations to you.

b) Where message text goes, by plan

• Free plan — Google Translate: text to be translated is sent directly from your browser to Google's translation endpoint (translate.googleapis.com). It does not pass through our servers. Google processes it under its own terms and privacy policy (policies.google.com/privacy).
• Free plan — browser built-in translation: where your browser supports it (for example, Chrome's built-in Translator API), translation runs on your device using a language model downloaded by the browser. In this mode the message text is not sent to us or to a translation provider by the Extension.
• Pro plan — AI translation: text to be translated, together with your chosen target language and translation style, is sent from your browser to our server, which forwards it to a translation provider: a third-party AI translation provider (we choose the provider based on cost and quality, and it may change over time). The translation is returned to your browser. Our server processes the request in memory only and does not store or log message content. We record only non-content usage data needed for billing and limits (for example, number of requests or characters, timestamp, and your account or license ID).

These providers process text under their own terms. Where a provider offers it, we use settings or API terms under which submitted data is not used to train their models. Providers may retain request data for a limited time for abuse monitoring or legal reasons under their own policies.

c) Settings

Your preferences (such as your language, target languages, display mode, translation style, and daily free-translation limit) are stored in your browser using the extension storage provided by your browser. If you have browser sync turned on, your browser may sync these settings across your devices. The Extension also keeps, in local (non-synced) storage only: a random installation ID, a count of characters sent to Google Translate today (used for the optional daily limit; it is never sent to us), and, if you sign in, your session token, email and device list.

d) Account, sign-in, license, and payment information (Pro plan)

Signing in is optional; the free plan works without an account. To sign in you enter your email address and we email you a one-time code. The code is valid for 10 minutes; we store only a salted hash of it and delete it once used. After you sign in, the Extension stores a random session token in your browser; our server stores only a hash of that token, and it expires after 180 days or when you sign out or remove the device. Sign-in emails are sent through Cloudflare's email service.

If you buy Pro, we receive your email address, license key, subscription plan and status, country, and transaction records from our payment provider, Paddle (Paddle.com Market Ltd and its affiliates, “Paddle”), which acts as the merchant of record and processes your payment. We do not receive or store your full card number. The payment provider handles your payment information under its own privacy policy.

e) Signed-in browsers and devices (Pro plan)

Your Pro plan works in every browser where you sign in, up to a device limit (3 registered browsers, 2 in use at the same time). To provide this and to prevent account sharing, when you sign in the Extension creates a random installation ID for that browser and stores it in the Extension's local storage. We keep that ID along with: your account email; browser name and version; operating system name; an optional device label; when the device was added and last active; and counts of translation requests (counts only, never message text). You can see and remove your devices at any time. We do not use device fingerprinting. We do not read, collect or store your identity on any chat platform, such as your WhatsApp phone number or Telegram username. The free plan can be used without signing in.

f) Voice messages (upcoming Voice feature)

Voice-message transcription is not available yet. When it launches, it will be off by default. If you turn it on, the Extension sends the audio of the voice messages you choose to transcribe to our server. Our server forwards the audio to a third-party speech-to-text provider, only to turn it into text. The text is then translated as described above. We do not store voice audio or transcripts on our servers. Audio is processed in memory and not written to logs. The speech-to-text provider processes audio under its own terms and may keep request data for a limited time for abuse monitoring or legal reasons. We will update this policy, including the provider table below, before the feature launches.

g) Support emails and chats

If you contact support, we keep your message and email address to respond and to keep a record of support requests. Support messages may be handled first by an AI support assistant provided by a third-party AI provider, which drafts or sends answers. Issues it cannot resolve are passed to a human. Please do not send passwords, full card numbers, or private chat content unless needed to resolve your issue.

h) Abuse prevention

To rate-limit requests to our server (for example, sign-in attempts), we keep short-lived counters keyed by a salted hash of your IP address or email address. We do not store raw IP addresses in these counters, and they are deleted automatically, normally within a few days.

2. Information the website collects

The translate.chuyi.ai website is a static site hosted on Cloudflare. When you click “Upgrade” in the Extension, the pricing page receives your account email and an account ID in the part of the address after “#”, which is not sent to any server; the page passes them to Paddle checkout so your purchase is linked to your account. Cloudflare may process technical data such as IP address and browser information to deliver and secure the site. We do not use analytics on the website. We do not use advertising cookies. The website stores your language preference in your browser's local storage.

Affiliate referrals. If you arrive through an affiliate link, the affiliate platform we use to run the program may set a cookie or similar identifier, for the period stated on our Affiliates page, so a later purchase can be credited to the referrer. The referrer sees only that a referred sale occurred, not your message content.

Telegram community. Our public Telegram group is run on Telegram. Anything you post there is visible to other members and is governed by Telegram's terms and privacy policy.

3. How we use information

• To provide translations you request and operate the Service.
• To manage your subscription, license, and usage limits, and to prevent abuse.
• To respond to support requests.
• To comply with legal, tax, and accounting obligations.

We do not sell or rent personal information, use message content for advertising, build profiles from your chats, or use your message content to train our own models.

4. Chrome Web Store Limited Use

The use of information received from Google APIs and the Chrome extension platform will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements. User data is used only to provide the Extension's single purpose (translating chat messages), is transferred only as described in this policy to provide that purpose, and is not used or transferred for any other purpose.

5. Service providers

6. International transfers

We are located in Canada. Our service providers may process data in the United States, the European Union, and other countries, where privacy laws may differ from those in your country. We rely on these providers' contractual and legal safeguards for such transfers.

7. Retention

• Message content: not stored on our servers.
• Account data (your email, subscription status, device records, usage counters and support correspondence): kept while your account is active, and deleted within 30 days after you ask us to delete it.
• Billing and transaction records: kept by Paddle, our merchant of record, as required by law (for example, tax and accounting laws).
• Device records (installation ID, browser, last active): kept while the device is on your account; deleted when you remove the device or close your account.
• Sign-in codes: deleted when used, and invalid after 10 minutes. Session tokens (stored hashed): until you sign out, remove the device, or 180 days. Rate-limit counters: normally a few days.

8. Security

Data in transit between the Extension, our server, and providers is encrypted with HTTPS/TLS. No method of transmission or storage is 100% secure, but we take reasonable measures to protect information.

9. Your rights and choices

Depending on where you live (for example under Canada's PIPEDA, the EU/UK GDPR, or California law), you may have the right to access, correct, delete, or receive a copy of your personal information, and to object to or restrict certain processing. To make a request, email hi@translate.chuyi.ai. We delete your account data within 30 days of a deletion request (billing records held by Paddle are kept as required by law). You can also stop all processing by the Extension at any time by disabling or uninstalling it, and you can clear its settings by removing the Extension. You may complain to your local data-protection authority, such as the Office of the Privacy Commissioner of Canada.

10. Children

The Service is not directed to children under 13 (or under 16 in the EU/UK), and we do not knowingly collect their personal information.

11. Changes

We may update this policy. We will post the updated version on this page with a new "Last updated" date and, for material changes, give notice through the Extension or by email.
