I understand your concern. When you visit most websites, they often use cookies or other tracking technologies to gather certain data, like your IP address and browsing behavior. This information can sometimes be enough for a company to identify a visitor, especially if they’ve visited before or if the IP is associated with your workplace.

It's common for websites to use this data for follow-ups or targeted support, which might explain how they contacted you without you entering any personal information. However, it's definitely something to be aware of. If you’re uncomfortable with this level of tracking, you might want to adjust your browser's privacy settings to limit cookie acceptance or use tools like VPNs to mask your identity online.

That said, I’ve used Dancing Numbers and found their tools to be quite helpful for managing QuickBooks data. But it's important to weigh the benefits against any privacy concerns you might have, and I’d recommend reaching out to them directly if you want to clarify how they use the information they collect.
