alt Hacker NewsI don't actually see this as a problem, and instead it's a PSA everyone needs to internalize:
If you put data onto a networked device it may be sent to some place else.
If you don't want your data being shared:
Use a device that does not have any networking capability (both hardware and software wise)
Use a pen and paper, you can shred and destroy as you see fit.
If you're using an application on a mobile device with mobile data/wifi, the chances are, your data is being uploaded.

Of course you do, your comment is just clickbait. Here's why:

Okay, go on, perhaps you have an interesting point

If it's not a problem, it's not a PSA because nobody needs to know or care. If it's something worthy of a PSA, then it must stem from a problem.
It sounds like the real solution to this is to be able to control permissions at an OS level for network per app, as you would be able to do if you had root access. I have no idea why regular Android distros don't allow you to do this, it seems like a really sensible thing to expose in app settings given the permissions model of Android.
Also: if you are not paying the service provider for the service, you are not their customer - you are their product.
You can use a networked device, but make sure the data is stored somewhere you control (and own).
There are four open source period tracking apps on F-droid. I didn't do a full investigation of the source code, but unless your data is being uploaded outside the app (e.g. for backups), I feel safe assuming it will stay local only.
