Privacy
Peer Overlap · last updated 16 July 2026
Short version: there are no accounts, we don't track you, and there are no ads or analytics. To be a good citizen of PeeringDB's shared database, your searches do pass through our own server — so this page explains exactly what that means.
There's no account, and no sign-in
Peer Overlap doesn't have user accounts. Sign-in is currently switched off entirely, so we never receive your name, email, or any PeeringDB profile. There is nothing to log in to and nothing for us to hold about you.
What's stored on your device
Your browser keeps a local cache of the public PeeringDB data you've looked at, for up to about a day. This exists so the app is fast and so we don't ask PeeringDB the same question repeatedly. It's ordinary public data — which networks are at which facilities — not anything about you.
It lives only in your browser and never leaves your device. Clearing your browser's site data for this site removes it.
What our server sees
Your searches are sent to our server, which then asks PeeringDB on your behalf and caches the answer to share with everyone else. That means the search itself (for example, "which facilities is AS13335 at?") and your IP address reach our infrastructure — as they would with any website you visit.
We don't build profiles, set tracking cookies, or keep our own record of who searched for what. Our site is hosted on Cloudflare, which handles the requests and keeps its own standard operational logs under its privacy policy.
The shared cache stores only PeeringDB's public answers, filed under the question that was asked. Nothing identifying is attached to them, and every visitor is served from the same cache.
No tracking, no ads, no analytics
There are no analytics tools, no advertising, no third-party trackers, and no third-party scripts of any kind. This isn't only a preference — PeeringDB's Acceptable Use Policy forbids using their data for advertising or commercial purposes, and Peer Overlap is a non-commercial tool built to respect that.
Links you share
When you share a comparison link, the address itself contains your selection — public network and facility IDs, and which view you were on. That's how the link reproduces your query for whoever opens it. Nothing private is encoded, but anyone with the link can see the comparison it describes.
Where the data comes from
All network, exchange, and facility data comes from PeeringDB, a public community database, and remains subject to their policies. Peer Overlap is unofficial and not affiliated with or endorsed by PeeringDB.
Changes
If what the app does changes — for example if sign-in is switched on — this page gets updated to match. It's meant to describe how the app actually behaves, not to be a catch-all disclaimer.
