Privacy notice
This notice explains what information Polling Interval handles when you read the site, use a Netcalc tool or write to us. We collect as little as we can.
Reading the site
Every page is readable without an account. We run no analytics or advertising trackers of our own, and no social media plug-ins that follow you between sites.
Like any web server, ours briefly records technical details of each request (the address requested, the time, your IP address and browser type) to keep the site running and to stop abuse. These logs are kept for a short time and then deleted. Our hosting and content delivery providers process this data for us to deliver the pages.
Netcalc tools
The calculators run in your browser. The addresses, counter readings and other values you type are not sent to us or stored anywhere.
Writing to us
The contact form sends us your name, the email address you give, the subject and your message. We use them only to read and answer you. Messages are kept for up to two years, then deleted unless the conversation is still going. We never sell or share them and never add you to a mailing list. Please do not send passwords, SNMP community strings or full device configurations.
Affiliate links and their cookies
Some articles link to products on Amazon or to other shops through the CJ Affiliate network. These links carry an identifier for this site, so the shop can credit us with a small commission if you buy something. As an Amazon Associate I earn from qualifying purchases.
When you click such a link, the shop or the network (Amazon, or CJ and the advertiser) may set cookies in your browser to record that the visit came from here. That happens on their sites, under their own privacy notices, and only after you click. A few pages show a labelled sponsored banner served by the CJ network; loading its image lets the network count the view. We receive only summary reports of clicks and orders, never your name or what else you bought.
Cookies
The public site sets no cookies of its own. See the cookie policy for the one technical cookie used by the editors' sign-in page and for the third-party cookies mentioned above.
Your rights
Depending on where you live (for example under the EU or UK GDPR, or US state privacy laws such as California's), you may have the right to ask what we hold about you, to have it corrected or deleted, or to object to how it is used. Write to us through the contact page and we will answer within 30 days.
Changes
If this notice changes, the date at the bottom of the page changes with it.
