Privacy notice.
What we collect from visitors, and what we do with client information. Last updated September 26, 2026.
This page covers two things: what happens when you visit zerbygroup.com, and how we handle information clients share with us during a project.
What we collect from visitors
What you type. Our contact form asks for your name, email address, business name, and whatever you write in the message box. The business name is optional. A third party form service receives the submission and passes it to our email. We keep those messages so we can respond and so we have a record of the request.
What your browser sends. Every page load sends standard technical information: your IP address, your device and browser type, the page you asked for, and the page that referred you. Our hosting provider and our analytics receive that information.
Analytics and cookies
We use Google Analytics 4 on every page. It tells us which pages get read, how visitors arrive, and which links get clicked. We track three actions: a contact form submission, a click on our phone number, and a click through to the client portal.
This site sets analytics cookies. It does not set advertising cookies and it does not run cross site tracking pixels. We do not sell visitor information. You can refuse or delete cookies in your browser settings, and you can block analytics with a browser extension. Blocking them does not break the site.
We serve our fonts from our own domain, so loading a page does not send a request to a font provider.
Do not send sensitive information through this form
Do not send Social Security numbers, employer identification numbers, bank or card numbers, or copies of sensitive documents through our contact form or by email. Email and web forms are not secure channels. Clients send documents through the client portal, which requires a login.
Client information
When you hire us, we handle what the project needs: access to the accounts and tools we are building on, business documents, and the data your new system will process. We use it only for your project. We share it only with you, with anyone you tell us in writing to send it to, with the vendors that run the tools you approved, and when a court order, a subpoena or a law requires it.
We do not sell client information. We do not share it with anyone for their own marketing. We will not name you as a client, publish a testimonial, or write a case study about your business unless you agree to it in writing first. If we ask, you are free to say no, and saying no does not change the service or the price.
How we protect information
We maintain a written information security program covering the systems that hold client information, and we review the vendors that process it. We do not publish the specific controls we use. Publishing a security control tells an attacker what to expect and turns a technical decision into a public promise, so we describe our safeguards to clients in the engagement letter instead.
No method of transmitting information over the internet is completely secure. If an incident affects your information, we will notify you as required by law and within the deadlines that apply to us.
Retention, your choices, and the rest
Retention. We keep client records for as long as the engagement and the law require, and contact form messages for as long as we need them to respond and keep a record. Some records we are required to keep for a set period even after an engagement ends.
Your choices. You can decline to provide information, adjust your browser cookie settings, or block analytics. To ask what information we hold about you, or to ask us to delete something you sent us, use the contact details below. Some records we cannot delete on request because we are required to retain them.
Children. This site is for businesses and is not directed to children under 13. We do not knowingly collect information from them.
Changes. We may update this page. The last updated date at the top will change when we do.
Contact. Questions about this page, or about information we hold, go to [email protected] or (630) 492-1318. Zerby Group LLC is based in St. Charles, Illinois.
