Privacy Policy

Last updated: November 2026. Zero tracking cookies, zero user behavioral profiling.

1. Zero-Cookie Architecture

TCO Audit (https://tcoaudit.com) does not set tracking cookies, marketing pixels, cross-site identity graphs, or behavioral retargeting scripts on your browser. You can browse, run simulations, and export migration briefs without an account, email gate, or cookie consent banner.

2. Client-Side Calculator Processing

All financial variables entered into our interactive workbenches (task counts, contact list sizes, email frequency, deal values, and reply rates) are evaluated locally inside your browser's JavaScript runtime. These operational figures are never transmitted to our servers, logged in databases, or shared with third parties.

3. Edge Audit Endpoint (`/api/audit`)

When you submit a domain to the Live SEO, TTFB & llms.txt Grader, our edge worker makes a server-side HTTP request strictly to fetch the target domain's publicly available HTTP headers, HTML metadata, /robots.txt, and /llms.txt file. We do not inspect, log, or index private data behind authentication walls. Audit results may be cached at the edge for up to 24 hours to prevent unnecessary traffic against origin web hosts.

4. Aggregate Redirect Telemetry (`/go/*`)

When you click an outbound software link routed through /go/*, our Cloudflare edge router records non-identifying aggregate counters (referring tool page, vendor slug, coarse two-letter country code, and bot status). We do not log IP addresses, browser fingerprints, or personal identifiers.

5. Third-Party Websites & Affiliate Networks

When you click an outbound link to provision software, you leave TCO Audit and enter the respective vendor or affiliate network platform (such as PartnerStack, Impact.com, Railway, or Systeme.io). Those independent services operate under their own privacy policies and terms. For full details on partner compensation, review our Affiliate Disclosure.
