Plume takes the privacy of our users seriously. As part of our parental control and security offering, Plume needs to collect the DNS request information (not URLs) and sends it to the cloud to identify web-based sources that may have potential security risks. We only store the requests that are flagged as potentially fraudulent. Additionally, these DNS requests are only accessible to the user using the Plume App, and are not viewable by any Plume personnel.
If you do not want to send any DNS requests to the Plume cloud, you can simply disable Secure and Protect, Ad-blocking and other security features via the Plume app.
