Paraphrasing my doctor: infections have evolved to the point the fever isn’t effectively contributing to fighting the infection, but we never evolved to stop making the fever. Since it doesn’t do us any good, we might as well be as comfortable as possible while our immune system does it’s part.
While I appreciate you trying to make it so, my privacy isn’t your responsibility. Option 3 is the way to go to keep your costs down, which is the long-term best solution.
It wasn’t one of the options, but from a user perspective a hybrid solution is best. Making a local copy that has a 24-48 hour cache keeps your storage down but still gives us the benefit of option 1. But it sounds like this would require some changes to how the server software works, which would be cool, but again you shouldn’t feel compelled to attempt.
Keep your costs and stress low wherever possible and thank you for everything you do.
