SpecCalc Hub
Privacy Policy
Last updated: June 20, 2026. Legal version: v1.5.0. Read this version together with the current public product behavior, calculator limitations, digital-delivery wording, and any active payment or analytics controls visible on the site.
SpecCalc Hub is built around a privacy-first public model: no user accounts, no contractor-matching forms, no lead capture workflow and no server-side storage of calculator input history in the normal public flow.
The product is designed so that a visitor can open a page, run a calculation, review the assumptions and leave without creating a personal profile. This product choice reduces operational overhead and narrows the amount of personal data the public site needs to touch at all.
Privacy-first does not mean there is literally zero technical telemetry anywhere; it means the platform is intentionally limited to the minimum technical records needed for operation, security and controlled digital delivery.
What the public calculator flow does not request
The normal public calculator flow does not ask for name, phone number, home address, passport, PINFL, STIR, payment card number, login password or similar identity-sensitive information. Public calculator use is not structured around personal registration.
Calculator inputs such as power, voltage, hours, tariff, conductor size, battery capacity or other technical entries are intended to be processed client-side in the browser under the current product model. The platform is not designed to keep a user-specific saved calculation history on the server.
If you voluntarily send a support message by email, the contents of that email will naturally be processed through the email channel you used. That communication is separate from anonymous page use and should not be confused with background collection from public calculations.
Allowed technical records and analytics boundaries
Where payment, PDF delivery or operational troubleshooting is involved, allowed technical order records are intentionally narrow: order_id, product_id, amount, currency, payment_status, timestamp and payment_provider. These records exist so that delivery or billing failures can be investigated without building a personal account system.
Analytics is configured in a privacy-conscious way. Allowed anonymous events may include page_view, calculator_opened, calculator_result_generated, premium_pdf_clicked, premium_pdf_download_free, paynet_button_clicked, theme_changed, language_changed and ad_banner_loaded. These events must not contain calculator input values or personal identity data.
The platform does not intentionally store full calculator histories, raw card data, passport identifiers, PINFL, STIR, home addresses, hidden fingerprint profiles or unrelated contact databases as part of the public calculator experience.
Third-party services, security and retention
Some operational functions depend on third-party infrastructure such as analytics, hosting, video delivery, payment services or external documentation links. Those providers may receive limited technical data necessary for their service to function and then process it under their own policies.
Security and operations logs may retain minimal technical information needed to detect abuse, errors, deployment incidents, uptime problems or suspicious requests. Such logging is intended for service integrity, not for hidden behavioral profiling.
Technical records should be kept only for as long as they are operationally justified by troubleshooting, legal accounting, abuse prevention or service continuity. The privacy-first model favors narrower retention and narrower data classes over broad indefinite storage.
Policy changes, user expectations and contact
If the data model, payment flow, analytics scope or storage behavior changes materially, the public policy should be updated together with the relevant product controls so that the visible product behavior and the written policy remain aligned.
Users should not assume that privacy-first means every external provider follows the same model. It means SpecCalc Hub intentionally limits what it collects and how the public product is structured, while third-party tools remain subject to their own operating rules.
