What AI apps collect on iPhone

Every iOS app has to tell Apple what personal data it collects. That declaration appears on the App Store as a privacy label, a short list of categories under “Data Linked to You.” It is not a full privacy policy and it does not prove how carefully a company handles data in practice. It is still one of the few places where developers have to put their claims in public, in Apple’s categories, next to the download button.

We counted the top-level categories for the big cloud chatbots and for Offeline. The chart on the homepage uses those numbers. Below is what each label lists, with App Store links so you can check the source yourself.

ChatGPT (8 types)

ChatGPT on the App Store declares these data types linked to you:

• Health & Fitness
• Location
• Contact Info
• User Content
• Search History
• Identifiers
• Usage Data
• Diagnostics

Eight categories is a lot for a chat app, and the list covers both the content you type and the identifiers that help a company keep track of who typed it. Whether every category is always collected for every user is something the label does not spell out. What it does say is that these types can be linked to you.

Gemini (12 types)

Google Gemini on the App Store declares:

• Purchases
• Location
• Contact Info
• Contacts
• User Content
• Search History
• Browsing History
• Identifiers
• Usage Data
• Sensitive Info
• Diagnostics
• Other Data

Gemini’s label is the longest of the four. It reaches into purchases, contacts, browsing history, and a catch-all “Other Data” bucket. That breadth fits a product that sits inside a large account ecosystem, but it also means the privacy label leaves less of your activity outside the “linked to you” frame.

Claude (6 types)

Claude by Anthropic on the App Store declares:

• Location
• Contact Info
• User Content
• Identifiers
• Usage Data
• Diagnostics

Claude’s list is shorter than ChatGPT’s or Gemini’s, though it still includes location, contact info, and the content of your chats. Fewer categories is better than more, but six linked types is still a cloud product collecting identity-adjacent data as part of normal use.

Offeline (0 types)

Offeline on the App Store declares no data linked to you.

That is not a slogan dressed up as a label, because the app runs open-source models on your iPhone. Prompts and replies never leave the device, so there is no cloud account trail of your chats to attach to an identity. If nothing is sent, there is nothing to categorize under “Data Linked to You.”

How to read the labels yourself

Open any app’s App Store page, scroll to App Privacy, and expand Data Linked to You. The categories above are exactly what those pages listed when we checked them in August 2026. Developers can update labels later, so if you need the latest version, verify it on the App Store rather than treating this page as permanent.
