Wuhan Tianchu Energy Storage New Energy Co., Ltd. (TIANCHU, “we”, “us”) is the controller for personal information collected through this website.
For privacy, data protection, and data processing agreement (DPA) requests: info@lithiumbattery.cc
No separate data protection officer (DPO) has been appointed for this website at present. If a DPO appointment becomes legally required, or if you want your request handled by the privacy contact, use the address above.
2. Information we process
- Project conditions, application, power, capacity, grid, ambient conditions, location, operating strategy, and contact details that you submit.
- Messages, attachments, and business information you provide when contacting us.
- Technical logs needed for security and delivery, such as IP address, browser type, request time, and requested page.
- Your cookie preference. The site currently uses only necessary local storage to remember that choice.
3. Purposes and legal bases
- Responding to inquiries, evaluating project requirements, and pre-contract communication: steps requested by you before a contract or our legitimate interests.
- Keeping the website, network, and forms secure and preventing abuse: our legitimate interests and applicable legal obligations.
- Enabling optional analytics or marketing technologies: your consent. These technologies are not currently enabled.
4. Sharing, processors, and transfers
We may disclose necessary information to website hosting, content delivery, cloud storage, email, and security providers. These providers may process information only on our instructions and should be bound by confidentiality and security obligations.
Where information is transferred outside the European Economic Area, we use an adequacy decision, standard contractual clauses, or another lawful safeguard where required.
5. Retention
Project inquiries and business correspondence are normally retained for no more than 24 months after the last meaningful interaction. If a contract, legal obligation, or legal claim requires longer retention, we retain the information until that matter ends and then delete it as required. Security logs are normally retained for no more than 30 days unless needed to investigate an incident. Cookie choices remain in your browser until you clear or change them.
6. Your rights
Where applicable, you may request access, rectification, erasure, restriction, data portability, or object to processing based on legitimate interests. You may withdraw consent at any time where processing relies on consent; withdrawal does not affect prior lawful processing.
Send a request to info@lithiumbattery.cc. We normally respond within one month; complex or numerous requests may be extended where permitted, and we will tell you. We may reasonably verify your identity.
You may also complain to the data protection authority in your country. The EDPB member authority directory can help you find the relevant authority.
7. Automated decisions and security
This website does not make automated decisions or profiling about visitors that produce legal or similarly significant effects. We use reasonable measures such as access controls, data minimisation, and secure transmission, but no internet transmission can be guaranteed absolutely secure.
