Privacy
This website is operated by Steven Michael Barber, doing business as Chimney Top Digital Services, a sole proprietorship based in Tennessee, who is responsible for the personal information described here. This policy covers chimneytopdigital.com. Each product has its own privacy policy, linked from that product, describing the data it collects.
What this website collects
This site sets no cookies and runs no advertising scripts. Fonts and images are served from our own domain, not third-party services.
The calculators are a separate site with their own privacy policy. Our browser extensions also have their own privacy policy, covering local data and Pro license checks.
To see which pages are read, this site uses Cloudflare Web Analytics, a service of Cloudflare, Inc. It counts page views and visits and reports which pages, referring sites, countries, browsers and devices they came from, plus page load timings. According to Cloudflare, it sets no cookies, does not use your browser's storage for this and does not build profiles of individual visitors. Cloudflare receives your IP address and browser details when the script loads, as any host does, and acts for us as a processor; its privacy policy is at cloudflare.com/privacypolicy. Our basis is our legitimate interest in knowing how the site is used. To avoid it, block the script (most content blockers do); the site works the same either way.
This policy covers the company website. For information collected by a product and the choices it offers, read the privacy policy linked from that product.
This site is served through Amazon CloudFront (Amazon Web Services), which keeps a log of each request: the time, your IP address, the address requested (with any query string), the referring page, your browser's user agent and your approximate country. We keep these request logs for 90 days, after which they are deleted automatically, and use them only to count visits in aggregate (page views, approximate visitors, referring sites), to watch for errors and slow responses, and to investigate abuse; never to identify or profile visitors, and never for advertising. Our basis is our legitimate interest in running the site securely and knowing how it is used.
Our endpoints for AI assistants, /api/mcp/extensions and /api/mcp/sheets (described under Connect an AI assistant), compute from the values an assistant sends and store nothing it sends. To limit abuse they count requests per network address in the memory of the function that answers them, one minute at a time; the endpoints themselves keep no log of addresses or requests. The request logs described above record each call's time, address and path, never what was sent. Our apps' own endpoints of the same kind are covered by each app's privacy policy.
