When AI and Secure Chat Meet, Users Deserve Strong Controls Over How They Interact

Both Google and Apple are cramming new AI features into their phones and other devices, and neither company has offered clear ways to control which apps those AI systems can access. Recent issues around WhatsApp on both Android and iPhone demonstrate how these interactions can go sideways, risking revealing chat conversations beyond what you intend. Users deserve better controls and clearer documentation around what these AI features can access.

After diving into how Google Gemini and Apple Intelligence (and in some cases Siri) currently work, we didn’t always find clear answers to questions about how data is stored, who has access, and what it can be used for.

At a high level, when you compose a message with these tools, the companies can usually see the contents of those messages and receive at least a temporary copy of the text on their servers.

When receiving messages, things get trickier. When you use an AI like Gemini or a feature like Apple Intelligence to summarize or read notifications, we believe companies should be doing that content processing on-device. But poor documentation and weak guardrails create issues that have lead us deep into documentation rabbit holes and still fail to clarify the privacy practices as clearly as we’d like.

We’ll dig into the specifics below as well as potential solutions we’d like to see Apple, Google, and other device-makers implement, but first things first, here’s what you can do right now to control access:

Control AI Access to Secure Chat on Android and iOS

Here are some steps you can take to control access if you want nothing to do with the device-level AI features' integration and don’t want to risk accidentally sharing the text of a message outside of the app you’re using.

How to Check and Limit What Gemini Can Access

If you’re using Gemini on your Android phone, it’s a good time to review your settings to ensure things are set up how you want. Here’s how to check each of the relevant settings:

• Disable Gemini App Activity: Gemini App Activity is a history Google stores of all your interactions with Gemini. It’s enabled by default. To disable it, open Gemini (depending on your phone model, you may or may not even have the Google Gemini app installed. If you don’t have it installed, you don’t really need to worry about any of this). Tap your profile picture > Gemini Apps Activity, then change the toggle to either “Turn off,” or “Turn off and delete activity” if you want to delete previous conversations. If the option reads “Turn on,” then Gemini Apps Activity is already turned off. 
• Control app and notification access: You can control which apps Gemini can access by tapping your profile picture > Apps, then scrolling down and disabling the toggle next to any apps you do not want Gemini to access. If you do not want Gemini to potentially access the content that appears in notifications, open the Settings app and revoke notification access from the Google app.
• Delete the Gemini app: Depending on your phone model, you might be able to delete the Gemini app and revert to using Google Assistant instead. You can do so by long-pressing the Gemini app and selecting the option to delete. 

How to Check and Limit what Apple Intelligence and Siri Can Access

Similarly, there are a few things you can do to clamp down on what Apple Intelligence and Siri can do: 

• Disable the “Use with Siri Requests” option: If you want to continue using Siri, but don’t want to accidentally use it to send messages through secure messaging apps, like WhatsApp, then you can disable that feature by opening Settings > Apps > [app name], and disabling “Use with Siri Requests,” which turns off the ability to compose messages with Siri and send them through that app.
• Disable Apple Intelligence entirely: Apple Intelligence is an all-or-nothing setting on iPhones, so if you want to avoid any potential issues your only option is to turn it off completely. To do so, open Settings > Apple Intelligence & Siri, and disable “Apple Intelligence” (you will only see this option if your device supports Apple Intelligence, if it doesn’t, the menu will only be for “Siri”). You can also disable certain features, like “writing tools,”
