Period Diary: Privacy First

I love this app because I use to have flo and it was a good app but it was a little bit complicated but this app is not complicated but I love it and every time it tells me exactly when I’m going to start my period and when I’m going to end it and so far it’s been right

I picked this app because the developer said your data doesn’t leave your phone. (Period math isn't so complex it needs to live on a server! I’m disturbed by all the other apps that take your info.) I was inclined to believe it because the the interface looked dignified and simple, made by one person and not a data mining company. App works great. I open the app to check when my period is supposed to start, I open to log when it does start, and I open to update the log to when it actually ended. You can adjust your standard period length and it will update its predicted dates, and if your period changes this month it will update future predictions accordingly.

I just downloaded this, happy to find an app that doesn’t track ridiculous things like kissing. I’d even happily pay $5 to remove ads if it works. However, the app defaults to the current date for your last period and the number of days out your period typically lasts as the end date. I can change the start date to the actual date of my last period, but i cannot change the end date. Every time I try, it goes back to the last day of the month, indicating a 27 day period...
