Key Takeaways

Google’s Gemini collects 22 different data points in total, more than any other widely-used chatbot.
xAI’s Grok collects the fewest data points from this sample set.

The harbinger of the AI revolution, ChatGPT, remains the most popular AI tool on the market, with more than 200 million weekly active users.

But amongst all its competitors, which AI chatbots are collecting the most user data? And why does that matter?

We visualize data from Surfshark which identified the most popular AI chatbots and analyzed their privacy details on the Apple App Store.

Their findings are as of February 18th, 2025.

Gemini, the Data Collection King

At first place, Google’s Gemini (released March, 2023) collects 22 different data points across 10 categories, from its users.

Data collected ranges from general diagnostics (that all bots in this study collect) to access to contacts (that no other bot identified collects).

Rank	AI Chat Bot	Total Data Points Collected	Categories
1	Gemini	22	Contact Info, Location, Contacts, User Content, History, Identifiers, Diagnostics, Usage Data, Purchases, Other Data
2	Claude	13	Contact Info, Location, User Content, Identifiers, Diagnostics, Usage Data
3	Copilot	12	Contact Info, Location, User Content, History, Identifiers, Diagnostics, Usage Data
4	DeepSeek	11	Contact Info, User Content, Identifiers, Diagnostics, Usage Data
5	ChatGPT	10	Contact Info, User Content, Identifiers, Diagnostics, Usage Data
6	Perplexity	10	Location, Identifiers, Diagnostics, Usage Data, Purchases
7	Grok	7	Contact Info, Identifiers, Diagnostics

Note: The Number of data points collected in each category vary per bot, leading to different totals.

xAI’s Grok (released November, 2023) collects the least unique data points (7).

China’s DeepSeek (released Jan 2025), sits comfortably in the middle of the pack at 11 points.

The kind of data collected by each of these AI tools varies. All of them collected general diagnostics information. However, only Gemini and Perplexity look at purchases.

And then, nearly all but Perplexity.ai and Grok collect user content.

User content is the kind of information that is usually linked to third party data and then sold to advertisers for targeted ads on the platform.

The general rule of thumb when it comes to data privacy is true for AI chatbots also. After all, information is stored on their servers, and those can be breached.
