Instander is an ad-free version of Instagram. Also, you can review all the data they (meta) has on you and you’ll see what websites have been sharing your data (whether you know it or not). You can check you ad preferences to see how they are personalizing things for you. From my understanding it’ll also base stuff off what your Instagram/fb friends view/like so even if you turn it off but your partner has shown any interest in it, you may get it too.
