What data AdGuard Home can collect and when
Processing DNS queries
AdGuard Home connects to the DNS servers configured as “Upstreams” and sends DNS queries to them.
Checking for updates
AdGuard Home periodically downloads a .json file to check if there’s a newer version. No information is sent when this happens.
Checking for filter updates
To check for updates for enabled filters, AdGuard Home connects to their respective servers. When this happens, nothing is sent to these servers. AdGuard Home periodically downloads a file containing all filter versions and their available updates.
Browsing Security domain check (disabled by default)
For each requested domain, AdGuard Home connects to the Browsing Security server and passes a 4-character prefix of the domain name’s SHA256 hash. The server responds with a list of full hashes and AdGuard Home checks if there’s a match. The sent prefixes are not stored and do not reveal any personal information.
Parental Control domain check (disabled by default)
For each requested domain, AdGuard Home connects to the Parental Control web service and passes a 4-character prefix of the domain name’s SHA256 hash. The service responds with a list of full hashes and AdGuard Home checks if there’s a match. The sent prefixes are not stored and do not reveal any personal information.
