The best way to access past data associated with a goal that you are not currently tracking is to use the data export feature:
Tap "More" in the lower right corner and then scroll to "Data Use & Privacy" and select "Export my data."
"Export my data" will securely send all of your Ovia data to date in the form of CSV files to the email address associated with your Ovia account. Please note, you will receive two emails with the same title - one will contain your fertility data, the other will contain your pregnancy data.
Stay tuned – the next Ovia update will include a feature to toggle back and forth between goals to access your data without an export.
