Privacy

Short version: the calculators run in your browser. Corrections and vendor suggestions are handled through forms hosted by FormRobin (links on Contact & corrections when the forms are open); an optional email address is used only to follow up on the submission, and a notification copy goes to the site owner. This site’s own files contain no accounts, newsletter, checkout, analytics or chat code, and no code that transmits calculator inputs.

As of 2026-10-26: this notice describes the current build and the hosted correction and vendor-suggestion forms. It will be revised if the site’s data handling changes.

Calculator inputs

Values you type (doors, subscribers, revenue, rates and similar) are read by the page’s own JavaScript to render results. They are not submitted to this site or stored. On 2026-10-26, the current files contained no fetch/XHR/beacon/WebSocket calls, no cookie-setting code and no localStorage/sessionStorage use.

Corrections and vendor suggestions

Correction and vendor-suggestion forms are hosted by FormRobin, a separate form service. The links appear on Contact & corrections when the forms are open. If you submit one, FormRobin processes the details you enter. We use them only to review the correction or suggestion and to check the source before any price or vendor detail changes. If you give an optional email address, it is used only to follow up about that submission; it is not added to a newsletter or used for marketing. A notification copy of each submission is emailed to the site owner. An optional screenshot is handled the same way, and the form asks you to crop account or customer details. FormRobin’s own terms and privacy policy apply on its pages. We have not independently verified FormRobin’s page scripts, cookies, retention, security or deletion practices, and this notice makes no claim about them. No calculator input is sent to FormRobin by this site.

Hosting

The pages are served by a static hosting provider. Like any web host, the provider may process connection data such as IP address, requested path, user agent and timestamps in its own logs. We have not verified the host’s logging, retention, security or deletion practices. The final hosting provider and its settings are owner-supplied at launch; no provider-specific privacy claim is made here.

Cookies and local storage

No cookie banner, cookie-setting script or local-storage access was found in the current site files. Root responses observed during the build check carried no Set-Cookie header. That is an observation about this build, not a guarantee about host-side processing or future changes.

Third-party links

Vendor and privacy links go to external sites. Their own terms and privacy practices apply once you follow a link.

Changes

If any other data collection, embedded content, accounts or checkout is added, this notice must be revised before those features are enabled. The hosted forms are described above. Questions or corrections: Contact & corrections (no monitored email address is published).
