I recommend not only disentangling yourself from Google products, (see my de-Google Your Life series on Patreon and Substack), but also think about leaving Meta, Amazon, Apple, and Microsoft.
This is a gradual process that takes time. In addition to holding monopolies, Big Tech has also entrenched us to become dependent.
Apps and programs are a good start. And don’t buy new devices from them. Break up with Big Tech by breaking them up.
