SpecCalc Hub Guide
Privacy-first calculators: what SpecCalc does not store
No accounts, no saved calculations, no lead forms, and no calculator inputs in analytics.
Browser-side math
Calculator inputs are processed client-side in the MVP.
Anonymous events
Only high-level event names may be logged, without input values or personal data.
Why it matters
Calculator inputs are processed client-side in the MVP. Only high-level event names may be logged, without input values or personal data. When that distinction stays hidden, it becomes easy to mistake a planning estimate for a real operating decision.
Formula or method
Review the public data flow: browser-side calculation, allowlisted anonymous events, and the limited technical records needed only for digital delivery or payment troubleshooting.
Worked example
Example: a public calculator run can generate an anonymous event such as calculator_result_generated without storing the actual input values, user name or contact details.
How to use in practice
Use this guide when a visitor, partner or reviewer asks how the public product handles calculator inputs, events and exports. It helps explain the boundary between browser-side math, anonymous product events and the limited technical records needed for support or payment troubleshooting.
Comparison table
| Topic | Value | Note |

| Anonymous events | Only high-level event names may be logged, without input values or personal data. | Practical context |
Checklist before using the result
- Check the units, equipment nameplate and real operating scenario first instead of trusting the nearest rounded number.
- Write down which factors the method models directly and which still need separate checking: losses, installation conditions, tariff structure or manufacturer behavior.
- Be explicit about the use case for the estimate: quick planning, option comparison, budgeting, team explanation or preliminary technical review.
- Before practical use, compare the result with equipment documentation, local rules and the real limits of the site.
Common mistakes
- Confusing no-account design with the absence of any technical security logs.
- Assuming third-party services follow the same privacy model without checking their own policy.
- Treating every export or PDF as if it automatically means personal-data storage.
Limitations
- The guide does not replace equipment datasheets, utility billing rules, local codes or field measurements.
- Even a detailed guide remains an explanation of method and does not become a certified engineering document.
What to check next
After this guide, read the public Privacy Policy and event-list description together. That gives the clearest view of what is deliberately not stored, what anonymous events can exist, and which technical records may still appear during payment or delivery troubleshooting.
When to use the calculator
Open Electricity Cost Calculator when you need to move from explanation into a transparent calculation with visible inputs, results and limitations.
FAQ
Is this a ready engineering decision?
No. This is a practical guide to the method, not a final project, certification or approval.
When should I open the calculator?
Open Electricity Cost Calculator when you want to test specific values, scenarios and assumptions instead of reading the method only.
What should I verify after this guide?
Check the equipment datasheet, local rules, real site conditions and the limitations of the chosen method.
Can I use this guide without the calculator?
Yes, if you need the method logic, common mistakes and limits first. For a real scenario, it is more reliable to open the calculator and test the numbers with your own inputs.
When do I need a professional instead of only this guide?
You need professional review when the result affects safety, installation, protective-device choice, equipment procurement, committed budget or local obligations. The guide is useful preparation, not final approval.
What is worth writing down after reading the guide?
Write down the key inputs, the result range you tested, the factors that still need manual verification and the document that will control the real decision. That short note makes the next calculator check, team review and supplier conversation more reliable. It also shows which uncertainty matters most in the scenario.
Are my inputs saved?
No, all inputs are processed client-side in your browser.
