Privacy levels
Using privacy levels you can specify which level of detail you want to see in your Pi-hole statistics. The privacy level may be changed at any time without having to restart the DNS resolver. Note that queries with (partially) hidden details cannot be disclosed with a subsequent reduction of the privacy level. They can be changed either from the Settings page on the dashboard or in FTL's config file.
The available options are
Level 0 - show everything¶
Doesn't hide anything, all statistics are available
Level 1 - hide domains¶
Show and store all domains as hidden
This setting disables
- Top Domains
- Top Ads
Level 2 - hide domains and clients¶
Show and store all domains as hidden and clients as 0.0.0.0
This setting disables
- Top Domains
- Top Ads
- Top Clients
- Clients over time
Level 3 - anonymous mode (anonymize everything)¶
Disable all details except the most anonymous statistics
This setting disables
- Top Domains
- Top Ads
- Top Clients
- Clients over time
- Query Log
- Long-term database logging
Level 4 - disabled statistics (v4.1+)¶
Disables all statistics processing. Even the query counters will not be available.
Additionally, you can disable logging to the file /var/log/pihole.log using sudo pihole logging off.
Note that - due to the disabled query processing - regex blocking is not available on level 4.
