Your data has monetary value to google. Giving them access, without getting any money from them (or even knowing what ways it will be used) is not something you must do.
If the app provides enough value that is unique to it, then thats OK, but if a data-respecting alternative exists that costs nothing to download or use, and fits the same (or more) needs, then using it just makes sense.
If thats not you, then thats ok.
I also use keep, but thats because I haven't degoogled my phone yet, so they already have most if not all of that data. Once I am in a position to be able to root and remove google without risking bricking my device (currently unhoused, and just cannot risk it rn), then I plan on never touching the damn thing.
To each their own.
Fortunatly, the cost to construct one has not changed similarly, and there are at least a few projects around the country (US) where land is owned by a charitable organization/person/collective and tiny homes are being as a solution for some people.
I really wish I knew of any in my area, I'm currently unhoused and live in a car, doing gigs for the greedy (waiting on a previous state to send mine my background info... for what is now 2 fucking months, so that I can be approved for working in my field) and living in a safe situation without the risk of others doing something to me, is something I very much want to have for the first time ever in my 30 years. I'm a cross country trans refugee, who's somehow unknowingly rented from a neonazi, a "friend" who robbed me, another "friend" that just took my (sub)rent money and split without paying the rent, or my childhood with an abusive family.... so I have concerns....
And a tiny home at a fair price/rate would likely be affordable for me, but I just haven't found anything.
