The first of these areas includes “user input,” a broad category likely to cover your chats with DeepSeek via its app or website. “We may collect your text or audio input, prompt, uploaded files, feedback, chat history, or other content that you provide to our model and Services,” the privacy policy states. Within DeepSeek’s settings, it is possible to delete your chat history. On mobile, go to the lefthand navigation bar, tap your account name at the bottom of the menu to open settings, and then click “Delete all chats.”
This collection is similar to that of other generative AI platforms that take in user prompts to answer questions. OpenAI’s ChatGPT, for example, has been criticized for its data collection although the company has increased the ways data can be deleted over time. Regardless of these types of protections, privacy advocates emphasize that you should not disclose any sensitive or personal information to AI chat bots.
“I would not input personal or private data in any such an AI assistant,” says Lukasz Olejnik, independent researcher and consultant, affiliated with King’s College London Institute for AI. Olejnik notes, though, that if you install models like DeepSeek’s locally and run them on your computer, you can interact with them privately without your data going to the company that made them. Additionally, AI search company Perplexity says it has added DeepSeek to its platforms but claims it is hosting the model in US and EU data centers.
Other personal information that goes to DeepSeek includes data that you use to set up your account, including your email address, phone number, date of birth, username, and more. Likewise, if you get in touch with the company, you’ll be sharing information with it.
Bart Willemsen, a VP analyst focussing on international privacy at Gartner, says that, generally, the construction and operations of generative AI models is not transparent to consumers and other groups. People don’t know exactly how they work, or the exact data they have been built upon. For individuals, DeepSeek is largely free, although it has costs for developers using its APIs. “So what do we pay with? What do we usually pay with: data, knowledge, content, information,” Willemsen says.
As with all digital platforms—from websites to apps—there can also be a large amount of data that is collected automatically and silently when you use the services. DeepSeek says it will collect information about what device you are using, your operating system, IP address, and information such as crash reports. It can also record your “keystroke patterns or rhythms,” a type of data more widely collected in software built for character-based languages. Additionally, if you purchase DeepSeek’s premium services, the platform will collect that information. It also uses cookies and other tracking technology to “measure and analyze how you use our services.”
The final category of information DeepSeek reserves the right to collect is data from other sources. If you create a DeepSeek account using Google or Apple sign-on, for instance, it will receive some information from those companies. Advertisers also share information with DeepSeek, its policies say, and this can include “mobile identifiers for advertising, hashed email addresses and phone numbers, and cookie identifiers, which we use to help match you and your actions outside of the service.”
How DeepSeek Uses Information
Huge volumes of data may flow to China from DeepSeek’s international user base, but the company still has power over how it uses the information. DeepSeek’s privacy policy says the company will use data in many typical ways, including keeping its service running, enforcing its terms and conditions, and making improvements.
Crucially, though, the company’s privacy policy suggests that it may harness user prompts in developing new models. The company will “review, improve, and develop the service, including by monitoring interactions and usage across your devices, analyzing how people are using it, and by training and improving our technology,” its policies say.
