Privacy policy
What SquidGrid collects, why, how long we keep it, and what we deliberately never collect.
Last updated 23 August 2026
Who we are
SquidGrid is a network monitoring service operated from Texas, United States. For any question about this policy or about data we hold, write to [email protected]. We answer privacy requests from that address and nowhere else, so it does not get lost behind sales mail.
What we collect
Account information
Your email address, the name of your organisation, and which people belong to it. Sign-in is handled by a third-party authentication provider; we never see or store your password. We keep a record of sessions so you can be signed out of a device you no longer control.
Measurement data
This is the service. For each destination you choose, we record round-trip time, packet loss, and the sequence of router addresses your packets crossed to get there. We also record which of your probes made each measurement, the version it is running, and the city you told it that it lives in.
Website information
Standard server logs: IP address, the page requested, and the time. We do not run advertising or third-party analytics, and we do not set tracking cookies. The only cookie we set is your sign-in session.
What we deliberately do not collect
The probe measures its own packets and the ICMP
responses they provoke. It has no capability to capture, inspect or store your
network traffic — this is a property of how it is built, not a policy we promise
to follow. The image is public at squidgrid/probe and you are welcome
to verify it.
- We do not measure your internal network. Your probe measures only the destinations you configure.
- We never task your probe with our own work. Probes you install serve you. They are never handed our measurement queue.
- We do not attempt to geolocate your probe from its address. It reports the city you configured, and nothing more precise than that.
- Your probes’ measurements are yours. The readings your probes produce — your targets, paths, latency, loss and route detail — power your dashboards, your history and your alerts, and nothing else. They are never published, never visible to any other customer, and never incorporated into SquidGrid’s shared or public network-health views or datasets. Everything SquidGrid publishes or shares is produced by SquidGrid’s own measurement fleet.
Why we hold it
To provide the service you asked for — measuring the destinations you chose and showing you the results — and to keep the service running and secure. Where the GDPR applies, our basis is performance of a contract for account and measurement data, and legitimate interests for security logging.
How long we keep it
| Data | Retained |
|---|---|
| Latency and loss samples | 30 days at full resolution |
| Hourly summaries | 400 days |
| Incident evidence | 180 days |
| Path and hop records | 180 days |
| Account and organisation records | Until you close the account |
Path and hop records are kept for 180 days, so a route today can be compared against the same route months back. If you want yours deleted sooner, ask and we will delete them.
Who else touches it
We use a small number of third-party providers to run the service — for authentication, hosting, network ingress, and email. They process data on our behalf and for no other purpose. A current list of our named sub-processors is available to customers on request, and we notify customers before adding a new one so they can object.
We do not sell personal information, and we do not share it for advertising. We have never received a government request for customer data; if that changes we will tell affected customers unless we are legally prohibited from doing so.
Your rights
Wherever you are, you can ask us for a copy of what we hold about you, ask us to correct it, or ask us to delete it. If the GDPR or the CCPA applies to you, you additionally have the rights those laws grant, including the right to object to processing and the right not to be discriminated against for exercising them. Write to [email protected] and we will respond within 30 days.
Where data is held
Our service and database run in Europe; our probes run in several countries. Measurement data therefore crosses borders by design — that is what measuring international paths means.
Changes
If we change this policy in a way that materially affects you, we will tell account holders by email before it takes effect rather than quietly changing the date at the top.
