What this site collects
Last updated November 9, 2026. ChurnWave is operated by Gold Street Software, LLC, 1108 S Main St, Unit 251, Greenville, SC 29601.
The free tools
Curve Split and Power Check run entirely in your browser. A file you open in Curve Split is read on your own computer. It is not uploaded, stored, or sent to ChurnWave or anyone else, and neither are the numbers you type into Power Check.
Analytics
The site uses Google Analytics 4, which sets cookies, to count page visits and clicks on a few buttons (booking links, the sample download, the contact form, and "a file was opened" or "a calculation was run" on the tools). Those events carry no contents from your file and nothing you typed.
The contact form and booking
The contact form is delivered to my inbox by Basin, a form service. It sends what you typed: name, work email, company, account range and your message. Booking a call is handled by Calendly, under Calendly's own privacy policy. I use these details to reply to you and for nothing else. I do not sell or share them.
If I emailed you and you would rather I didn't, reply and say so. I will not email you again.
Client data during an engagement
Access is read-only: restricted billing keys, a warehouse read role, or exported files. Your data is used only to produce your deliverables. Anonymized aggregates are used in benchmarks only if you opt in, in writing. A mutual NDA is available on request.
