I want to preface this by saying that yes, I know that Instagram is bad. I am planning to get rid of it in the future but as of now I have to keep it for communication with people who are only on that platform.

So I have grapheneOS, use protonvpn (free version), use mull as my browser, and do not have google play services enabled on my phone. I do have some apps downloaded through aurora store such as Instagram, whatsapp, mychart, and mint mobile, but the rest came from f-droid.

I have noticed multiple times that after having private conversations on matrix, I get Instagram content in my feed that is scarily accurate to the conversation I had on the other platform immediately after. I know that things discussed in Instagram direct messages and group chat will give suggested content based on those conversations, but I get stuff that that is very specific to what I have ONLY discussed on matrix and didn’t look up via my browser.

So my question is how is Instagram doing this and what can I do to mitigate the spying it’s doing on my other apps. Thanks.

    I feel a lot of these responses miss the mark. If I read it correctly, you suggest matrix is the data leak and the results of which show in Instagram.

    Matrix has many clients, one of which could be leaking data, but not necessary from your end of the conversation.

    There are also keyboards which analyze input, and high privileged apps that can read notifications.

    From what I understand, Meta apps can scan a device for a list of apps installed (probably somesort of fingerprinting concern) but can’t actually read app interactions or content.

    I’d say hi in a chat with some clear, unique keywords on a new or old/wiped device and see if the leak continues. It may not be you at all, but it would identify the problematic device
