Privacy Policy

This policy explains how Beijing Zhicheng Zhuoyue Technology Co., Ltd. (“we”) handles personal data when you use sinocite.com. We collect only what we need to run the service:

• Account: your email address, a name taken from it, and your password, which is stored hashed.
• What you check: brand names, other names, competitors and the prompts you enter, and the answers the engines return.
• Billing: your subscription status and Stripe customer ID. Card details are entered on Stripe’s page and never reach our servers.
• Abuse prevention: a one-way hash of your IP address (and email, if given) to enforce the daily free check limit.
• Basic server logs needed to operate and secure the service.

We use this data to run your checks, show your results and history, bill your subscription, answer your emails and prevent abuse. We do not sell personal data, and we do not use it for advertising.

Registered users get emails about their account. Only people who subscribe get our monthly report, and they can unsubscribe any time. We send these emails through Hostinger Reach.

To provide the service we share data with these companies:

• AI engines: your prompts are sent to DeepSeek, Alibaba Cloud (Qwen), Moonshot AI (Kimi), Zhipu AI (GLM), MiniMax and ByteDance (Doubao) through their official APIs. Their answers come back to us. Each provider handles that data under its own terms.
• Setup suggestions: when you ask for suggestions during setup, what you type is sent to DeepSeek.
• Stripe, which processes payments and stores your card details.
• tawk.to, which runs the chat window on our site: what you type in it, the email you leave, and basic technical data about your visit (browser, pages viewed, approximate location).
• Hostinger Reach, which sends our emails and stores the addresses of people who subscribe.
• Our hosting and email providers, which store data and deliver messages on our behalf.

Do not put confidential or personal information about other people in your prompts.

We keep your account, checks and run history for as long as your account is open, so you can see past results. Free checks that are not saved to an account are kept so their results link keeps working; email us the link if you want one deleted. When you ask us to delete your account, we delete its data, except records we must keep by law, such as billing records.

You can ask for a copy of your data, or ask us to correct or delete it, by emailing support@sinocite.com. Depending on where you live, you may have further rights, including the right to complain to your data protection authority.

We use only cookies the service needs: your sign-in session, the free check you just ran (so it can be saved to a new account) and the brand you last selected. The chat window, provided by tawk.to, sets its own cookies so a conversation continues across pages and visits. We do not use advertising or tracking cookies.

Our providers may process data in other countries. In particular, prompts sent to AI engines are processed by providers based in China. By running a check you ask us to send your prompts there.

We may update this policy. The date at the top shows when it last changed. If a change materially affects you, we will email you.
