Privacy Policy

Who we are

What this policy covers

This Privacy Policy explains what information we collect, how we use it, when we share it, and the choices you have. Our calculators are designed to be privacy‑friendly and simple to use.

Summary

  • We don’t require an account, and we don’t sell your personal data.
  • Most calculator inputs are processed in your browser and are not sent to our servers.
  • We use limited technical logs for security and performance.
  • Optional services (analytics, ads, contact forms) may collect additional data if enabled.

Information we collect

  1. Calculator inputs
  • By default, values you enter into our calculators are processed locally in your browser and are not stored by us.
  • Some tools may fetch external reference data (e.g., currency rates). Your typed values are not sent to those providers—only a request for rates or similar reference info.
  • If a feature allows you to “save” preferences, we store those locally in your browser (e.g., localStorage). You can clear them via your browser settings.
  1. Technical and usage data
  • Server logs: IP address, user agent, referrer, pages visited, date/time, and error codes. Purpose: security, debugging, fraud prevention.
  • Typical retention: 30–90 days, unless needed for investigations.
  1. Cookies and local storage
  • Essential: WordPress/theme/session, load balancing, security, cookie consent. These are necessary for the site to work.
  • Preferences: may save last used units, theme, or calculator settings in your browser.
  • You can block cookies in your browser, but essential cookies are required for core functionality.
  1. Contact forms and email (if used)
  • If you contact us, we receive your name, email, and message content. We use this to respond and improve support.
  • Retention: usually up to 12 months unless needed longer for legal reasons.
  1. Analytics (if enabled)
  • We may use privacy‑friendly analytics (e.g., Plausible/Umami) or Google Analytics 4 to understand aggregated usage and improve the site.
  • IPs may be anonymized; we do not use analytics to identify you.
  • Opt‑out/controls:
    • GA4: use your browser’s “Do Not Track”/ad settings or Google’s opt‑out tools.
    • Plausible/Umami: these tools don’t use cookies and don’t collect personal data.
  1. Advertising (only if enabled)
  • If we show ads (e.g., Google AdSense/Ad Manager), the ad provider may set cookies or use identifiers to measure performance and, where permitted, personalize ads.
  • In regions where required, we will ask for consent for personalized ads; you can choose non‑personalized ads.
  • Manage preferences via our cookie banner and your Google Ad Settings.

Lawful bases for processing (GDPR/UK GDPR)

  • Contract/Service provision: to operate calculators and deliver the website.
  • Legitimate interests: site security, debugging, preventing abuse, improving features.
  • Consent: non‑essential cookies, analytics, personalized ads, and marketing.
  • Legal obligations: complying with applicable laws and requests.

How we use information

  • Provide and maintain the website and calculators.
  • Improve accuracy, performance, and content.
  • Prevent fraud, abuse, and technical issues.
  • Communicate with you when you contact us.

Sharing your information

We do not sell your personal information. We share information only with:

  • Service providers (hosting, CDN, security, analytics, email) under confidentiality and data processing terms.
  • Legal and compliance: if required by law or to protect rights and safety.
  • Business transfers: in case of a merger, acquisition, or asset sale, subject to this Policy.

International data transfers

Your data may be processed in countries other than where you reside. Where required, we use appropriate safeguards (e.g., standard contractual clauses).

Data retention

  • Calculator inputs: processed in your browser; we do not store them.
  • Server logs: typically 30–90 days.
  • Contact/support data: up to 12 months (or as required by law).
    We may retain data longer if needed to resolve disputes or enforce agreements.

Security

We use reasonable administrative, technical, and organizational measures (including HTTPS/TLS) to protect data. No method of transmission or storage is 100% secure.

Your rights

If you are in the EU/EEA/UK:

  • Access, rectification, erasure, restriction, portability, objection, and withdrawal of consent at any time (without affecting prior processing).
  • Contact us at [support@[your-domain.com]] to exercise rights.
  • You may lodge a complaint with your local supervisory authority.

If you are in California (CCPA/CPRA):

  • Right to know, access, correct, delete, and non‑discrimination.
  • We do not “sell” personal information as defined by CCPA. If we engage in cross‑context behavioral advertising, you can opt out via our cookie banner or a “Do Not Sell or Share My Personal Information” link (if applicable).
  • Submit requests at [support@[your-domain.com]].

Children’s privacy

Our site is not directed to children under 13 (or under 16 in some regions). We do not knowingly collect personal information from children. If you believe a child provided personal information, contact us to delete it.

Third‑party links and content

Our site may link to third‑party websites. Their privacy practices are governed by their own policies.

Changes to this Policy

We may update this Policy from time to time. Changes will be posted on this page with an updated “Last updated” date. Material changes may be communicated more prominently.
