Stop data collection
If you want to stop your participation in the study (without deleting the collected data), you can just delete the app. This way, you will not receive further notifications but your data will stay available for the researcher.
Remove data
There are two ways to remove your data.
Block a practitioner/researcher
You can remove your data by blocking the practitioner/researcher that collected them. To block a practitioner/researcher, follow these steps:
Go to the app settings

Go to My practitioners

Tap on Block

When you’ve blocked a practitioner, the practitioner’s/researcher’s box will turn grey and the Blocked icon will turn blue.
Delete online data
You can delete your online data via the app settings. If you delete your online data, your data will be deleted, you will be disconnected from all your practitioners/researchers and your app account will be deleted. To delete your online data, follow these steps:
Go to the app settings

Tap on Delete online data

Tap on Yes

Tap on Yes

Tap on Delete

Reinstall the app
Delete the app and reinstall it from the App or Play Store.
