Yes. No signup required, no data collected, nothing sent to our servers. Everything runs in your browser. We publish free tools because they build trust with operators who might eventually hire us — that's the entire business model.
The math is correct and the formulas are standard. The output is only as good as the inputs you provide — garbage in, garbage out applies here like anywhere. We recommend calibrating with at least 3 months of real data before making major decisions based on the results.
The tool lives at a stable URL that you can share with your team. We don't currently offer embeds, but the output is shareable via the copy button on calculator results. For white-label or embedded versions, contact us directly.
Three reasons. First, they help operators make better decisions even if they never hire us. Second, they let us show our thinking publicly — the frameworks behind these tools come straight from our client engagements. Third, they attract the kind of operators who later become great clients.
The free tools cover standard scenarios. For custom analysis — multi-channel attribution, cohort LTV modeling, MMM — we do this as part of paid engagements. Our CRO & Analytics service starts at $6k/month and includes custom dashboarding plus BigQuery setup if needed.
