CalcBold

Privacy Policy

Effective 2026-07-24

1. Who we are

CalcBold (“we,” “us,” or the “Service”) is operated by SemiSoftwares. This policy applies to calcbold.com and any subdomains we operate, covering both the store and the free sizing calculators.

2. What we collect — by surface

Calculator inputs. Every value you type into a calculator (weight, salary, loan amount, etc.) is processed entirely on your device. We do not store, log, or transmit it to our servers — with one named exception: the AI insight feature (section 5).

Anonymous analytics. If you accept analytics cookies, Google Analytics 4 captures page views, approximate region (city level via Cloudflare CDN), device type, browser, and time on page. IP anonymization is enabled. We never collect a name, email, account, or any value you typed into a calculator.

Server access logs. Our web server records standard request logs — IP address, timestamp, user agent, requested URL — for 30 days, used solely for security incident investigation and abuse mitigation. Logs are not linked to analytics and are not shared with third parties.

Local browser storage. Your shopping cart, plus any bookmarks, calculation history, saved scenarios, or recent searches, live in localStorage on your device. They never leave the browser. Clearing your browser data removes them completely.

Order details. When you place an order we collect your name, email, shipping address, billing address, and the contents of the order. We need all of it to fulfill and support the purchase, and we keep it for as long as tax and accounting law requires. Section 6 covers what happens to it.

Email address, if you subscribe. The newsletter stores only your email address and the date you subscribed. Every email carries a one-click unsubscribe, and unsubscribing deletes the record rather than suppressing it.

3. Cookies and consent

On your first visit, a banner asks whether you accept analytics + ad cookies. The default — and what stays in effect if you reject or ignore the banner — is everything denied:

  • Functional cookies (always loaded) — your light/dark theme preference. Single key, no tracking value, no third-party transmission.
  • Analytics cookies (consent-gated) — Google Analytics 4 cookies (_ga, _ga_*) record anonymous session metrics. Only loaded after you click Accept on the banner. Implementation uses Google Consent Mode v2 — the GA tag itself loads at default-deny, so nothing is recorded until you opt in.
  • Advertising cookies (consent-gated) — Google AdSense personalization cookies. Same gate as analytics. Reject and ads remain non-personalized (contextual based on the page topic only).

If your browser sends Sec-GPC: 1 (Global Privacy Control) we treat the request as a Reject regardless of what the banner says — your browser’s opt-out is authoritative.

4. Advertising

The store itself carries no third-party advertising. Where ad slots are enabled on calculator pages they are served by Google AdSense and are clearly framed and labelled. Product pages, cart, and checkout are ad-free by design.

AdSense may use cookies to serve personalized ads if you accept on our banner. You can opt out site-wide via Google’s Ad Settings. We never share your calculator inputs with advertisers.

5. AI-powered insights

When you run a calculator, an “AI insight” panel sends the values you typed and the computed result (not any personal information) to our API route at /api/insight, which forwards the minimum required payload to Anthropic’s Claude API for a plain-English explanation.

What we send to Anthropic:

  • The calculator id (e.g. loan-emi-calculator).
  • The numeric values you entered.
  • The result our formula computed.

What we do not attach: IP address, cookies, account identifiers, browsing history, advertising identifiers, location.

Per Anthropic’s API terms, your inputs are not used to train models. Insights are cached in your browser’s localStoragefor 24 hours so the same inputs don’t trigger duplicate API calls.

For extra privacy, you can block requests to /api/insight in your browser’s ad-blocker. The calculator itself will still work; a default explanation will appear in the insight panel.

6. Orders, payments, and shipping

Card details never reach us. Payments are processed by Stripe. Your card number is submitted directly to Stripe over an encrypted connection and is never transmitted to, or stored on, CalcBold servers. We receive only the card brand, the last four digits, and whether the charge succeeded, which is what appears on your receipt. Stripe acts as an independent controller for the payment data it collects; their privacy policy governs it.

Shipping data goes to the carrier and the warehouse. Your name, delivery address, and phone number, where provided, are shared with the fulfillment partner shipping your order and with the carrier delivering it. They receive only what is needed to deliver the parcel, and they are not permitted to use it for their own marketing.

Order retention. We keep order records for as long as tax, accounting, and consumer-protection law requires, which in the US is generally seven years. You can ask us to delete everything not covered by that obligation at any time, and we will.

What we do not do with it. We do not sell customer data, we do not share it with data brokers, and we do not upload customer lists to advertising platforms for targeting or lookalike audiences.

7. Optional monitoring services

The site operator may enable any of the following privacy-respecting services in production. None are loaded if their respective environment variable is unset:

  • Microsoft Clarity — heatmaps + session replay. Activates only if NEXT_PUBLIC_CLARITY_ID is set. Replay is mouse-trail only — input field values are masked by default.
  • Cloudflare Web Analytics — privacy-respecting real-user-monitoring. No cookies, no fingerprinting.
  • Sentry — frontend error tracking. Captures JavaScript exceptions only, not calculator values.

8. Third parties referenced

9. Your rights — GDPR & CCPA

Because we do not store personal data tied to individual users, there is no account to delete and no stored dataset to export. If you believe we have information about you through third-party integrations, you have the following rights regardless of jurisdiction:

  • Access. Request a copy of any data we hold about you.
  • Rectification. Correct inaccurate data.
  • Erasure (“right to be forgotten”). Request deletion of any data we hold.
  • Portability. Receive data in a machine-readable format.
  • Object to processing. Withdraw consent at any time. Re-clicking the banner via localStorage.removeItem("cb_cookie_consent_v1") and reloading restores the consent prompt.
  • CCPA “Do Not Sell”.We do not sell personal information. Reject on the cookie banner is also our CCPA “Do Not Sell” switch.

To exercise any of these rights, email [email protected]. We respond within 30 days.

10. Children

CalcBold is designed for users aged 13 and over. We do not knowingly collect any information from children under 13. If you believe a child has used the service and that information may have been collected, email [email protected] and we will remove any applicable records.

11. Data security

The site is served over TLS 1.2/1.3 only. Cloudflare’s WAF provides DDoS and OWASP-rule protection. Our backend Anthropic API key is server-side only and never exposed to the browser. Server access is restricted to a single operator account; secrets are rotatable via a documented runbook.

12. Changes to this policy

We may update this policy as the Service evolves (new features, legal changes, additional integrations). Material changes will be reflected in the Effective date at the top of this page. Continued use of the Service after an update constitutes acceptance of the new terms.

13. Contact

Privacy questions, data requests, complaints: [email protected]. Order and support questions: [email protected], or the contact page. See the Terms of Use for the rules governing use of the site and the terms of sale.
