Pi-hole removes tracking from your network — and in doing so, it quietly becomes the most complete diary of your network's activity anywhere in the house. This page looks at that diary honestly: what it holds, who could read it, and the built-in settings that shrink it.
There is a fair trade at the heart of Pi-hole, and it should be made with open eyes. Sending all lookups to outside providers means they see everything; keeping lookups at home means your Pi-hole sees everything instead. Every domain, every device, minute by minute — websites visited, apps phoning home, when the house wakes and sleeps. That log is what makes the dashboard and the debugging in this series possible. It is also genuinely sensitive. Here is how to hold both truths and set Pi-hole up accordingly.
A DNS log does not show page content, messages or passwords. What it shows is arguably the next thing down: which services every device contacted, and when. From a week of logs, a reader can map the house's routines, the apps on each phone, the medical, banking and dating services visited (by domain), and when each person is home and awake. Treat the log with the respect you would give a browsing history — because functionally, it is close to one for the whole home.
Pi-hole builds the trade-off into its settings as privacy levels for its FTL engine. Lower levels keep full detail — best for debugging and the dashboard. Higher levels progressively hide domains, then clients, up to an anonymous mode that stores no log and shows no per-device statistics. The cost is real too: level up, and the query-log detective work in this series becomes impossible. A sensible home pattern: run detailed while you are setting up and fixing things, then step the level up for everyday life.
Recent queries live in memory and the log files, and long-term data is stored in Pi-hole's database on the Ubuntu machine (by default keeping an extended history, commonly up to a year, adjustable in settings). Shorten the retention to what you actually use — a month of history serves almost every debugging purpose. And remember the physical side: that database sits on a disk in your house. Whoever has the machine (or its backups) has the diary; an encrypted disk or a machine in a private room is proportionate care, not paranoia.
The web dashboard is protected by the admin password you set at install — keep it strong and unique, because it unlocks both the controls and the diary. Never expose the dashboard (or DNS port 53) to the internet; Pi-hole is a LAN tool, and an open resolver online is both a privacy leak and an abuse risk. If you must reach it from outside, come in through a VPN into your home network, not by publishing the page. Inside the house, remember the dashboard is reachable by anyone on your network who knows or guesses the password — on a shared or guest-heavy network, that means choosing the password like it counts.
Finally, the human setting, which no menu contains. If you run the network for a family or shared home, the honest move is to say plainly: our DNS runs through a box in the house, it can see which sites devices contact, and here is the privacy level it is set to. Pi-hole still improves everyone's privacy against outside trackers and providers — that part of the promise is real. It simply moves the trust to the person running the box. Being that person openly is what makes the arrangement fair.

▶️ Watch Full VideoThey can see the domains your devices contact and when — for example that a device reached a particular bank, mail service or video site, and how often. They cannot see the pages you read, your messages, or anything inside the encrypted connection. It is a meaningful record, which is why this guide recommends open conversation and a considered privacy level.
At the highest privacy level Pi-hole stores no query log and shows no per-device statistics, so the dashboard becomes very basic and the log-based debugging used in this series (finding which domain broke a site, proving a device bypasses) is no longer possible. It is the right choice when privacy matters more than the instruments.
No. Publishing the dashboard or DNS service to the internet exposes your household's query record and turns your Pi-hole into an open resolver others can abuse. If you need access from outside, connect into your home network with a VPN and open the dashboard as if you were home.
