Radical transparency
What we can see. And what we can't.
Most filters ask you to trust a black box. We'd rather show you exactly what a DNS service like ours can and cannot know about you — and the controls you keep over all of it.
How it works
Filtering needs the domain. Nothing more.
DNS turns a name like youtube.com into an address your device can reach. To block or allow it, we have to read that domain — and that is the whole of what we see.
youtube.com
Which video, your watch history, your account, or anything inside the page.
The full picture
What we keep — and what we never collect.
What we store
- The domain a device asks for, and whether it was allowed, blocked, or cached
- A category (e.g. social, ads, malware) and a timestamp
- Your account email, plan, device labels, profiles, and custom rules
- Aggregate counters — queries today, blocked today — for your dashboard
What we never collect
- Full URLs, search terms, or the contents of any page you load over HTTPS
- The IP address of the device making the query, in long-term storage
- Your real name — pseudonyms are welcome
- Anything sold, rented, or shared with advertisers or data brokers — ever

Security incidents or data breaches, ever
To date, Guardino has never received a government or law-enforcement request for user data, nor any order to hand over data or weaken our systems — and we have had no security breaches. If that ever changes, we will update this page, and we will challenge any request we believe is unlawful.
You decide how long anything lives.
Query logs are kept 30 days by default so you can review what was blocked. Paid plans keep more history for your own dashboard — 90 days on Pro and a year on Team. On any plan you can request deletion of your logs at any time.
Short-lived operational logs — the kind used to debug and stop abuse — are kept 14 days, then deleted automatically.
Where we're honest about limits
One strong layer — not a silver bullet.
DNS filtering is domain-level. We can block a whole domain, but we can't block a single bad page on an otherwise-fine site, and we can't see or change what happens inside an app once it has connected to a domain you allow.
So we don't pretend it replaces everything. It's one private, network-wide layer that covers every device at once. Pair it with on-device tools like Apple Screen Time or Google Family Link for timed limits, and you've covered far more than either does alone.

Don't take our word for it
Check it yourself.
Privacy you can audit beats privacy you have to trust. Here's how to confirm what this page says — in your own browser.
Run a DNS leak test
Confirm your queries resolve through Guardino over encrypted DNS — and don't leak to your ISP.
Open the DNS leak test→Check your connection
See whether you're on DoH/DoT and which resolver is answering you right now.
Check my connection→Read the binding policy
Our zero-log commitment and exactly what is and isn't stored are written down — and enforceable.
Read the privacy policy→Common questions
The questions people actually ask.
Can Guardino see the websites I visit?+
We see the domains your devices ask for — like example.com — because that is exactly what a DNS filter has to read in order to block or allow it. We do not see the full URLs, your search terms, or the contents of anything you load over an HTTPS connection.
Do you sell my data?+
No. We never sell, rent, or share your DNS data with advertisers or data brokers. Our revenue comes from subscriptions — not from your activity.
How long do you keep my query logs?+
30 days by default so you can review what was blocked. Paid plans keep more history for your own dashboard — 90 days on Pro and a year on Team. On any plan you can request deletion of your logs at any time. Short-lived operational logs are kept 14 days, then deleted.
Do you store my IP address?+
Not in long-term storage. The query metadata we retain is the domain, the allowed/blocked/cached status, a category, and a timestamp — not the IP address of the device that made the request.
Why don't you just promise you see nothing at all?+
Because it wouldn't be true. A DNS filter has to see the domain to decide whether to block it — claiming otherwise would be marketing, not honesty. What we can promise is a minimal footprint, full control over your data, and that it is never sold. We'd rather earn trust by being precise than by overpromising.
