This policy applies to all information collected within the RRate app for iPhone, iPad, or iPod.

Information saved

Information entered in the RRate app is stored locally on your mobile device. It is not automatically sent to anywhere. The app is perfectly useable with no network connection.

If the REDCap option is turned off, only the settings are saved. These settings simply include all options chosen on the app Settings pages. The settings are stored in a plain text file on the mobile device.

If the REDCap option is turned on, then each measurement of respiratory rate is saved temporarily on the device. Each one is deleted once successfully uploaded to your REDCap project. This data is stored in a constant database file (data.cdb file) on the device. The REDCap settings are described on the open-source RRate app GitHub page.

Information usage

We have no access to any data you collect. If you enter REDCap details for your instance of REDCap, these details are used to send the RRate measurement data directly to your instance of REDCap securely. The app acts as an HTTPS client, so the REDCap instance needs SSL setup with a valid certificate.

Your Consent

By using the RRate app, you consent to this privacy policy.
