Privacy Policy — CALCULATORPRO.io

This Privacy Policy explains how CALCULATORPRO.io ("we", "us", "our") collects, uses, stores, shares and safeguards information when you visit calculatorpro.io (the "Site") or use any of our calculators (collectively the "Services"). By using the Services you consent to the practices described in this Policy. If you do not agree, please do not use the Services.

1. Who we are

CALCULATORPRO.io is an online publisher of free calculators and reference content covering finance, health, math, taxes, conversions and everyday tools. We are the data controller for personal information processed in connection with the Site. You can contact us at any time at hello.toolskit@gmail.com.

2. Information we collect

We keep data collection to the minimum required to operate and improve the Services.

Information you provide. When you use our contact form, request a calculator, report a bug, or send us feedback we collect your name, email address, subject and message contents.
Calculator inputs. Numbers, selections and preferences entered into calculators are processed in your browser. We do not transmit, store or log your calculator inputs on our servers. Calculations run client-side.
Automatic / log data. Like most websites, our servers and Cloudflare edge network automatically receive standard request data: IP address (typically truncated for analytics), user-agent, referring URL, requested page, country, timestamps and basic device characteristics. This data is used for security, abuse prevention and aggregate analytics.
Cookies and similar technologies. See Section 4 below.
Information from third-party advertising partners. See Section 5 below.

We do not collect government-issued IDs, social security numbers, financial account credentials, or biometric data. We do not sell, rent or trade personal information.

3. How we use information

To operate, maintain and improve the Site and calculators.
To respond to your contact, support and calculator-request submissions.
To prevent fraud, abuse and security incidents.
To analyse aggregate usage and improve content and features.
To display advertising via Google AdSense (see Section 5).
To comply with legal obligations and enforce our Terms of Service.

4. Cookies & similar technologies

A cookie is a small text file stored on your device. We use cookies, local storage and similar technologies for the purposes below. You can control cookies through your browser settings and, for advertising cookies, through the consent banner described in Section 5.

Strictly necessary. Required for the Site to function — for example, remembering your light/dark theme preference (theme in localStorage) and language selection. These do not require consent.
Analytics. Aggregate, privacy-respecting metrics used to understand which pages and calculators are popular so we can improve them. We anonymise IPs where supported.
Advertising. Cookies set by Google AdSense and its partners to deliver, measure and (where you have given consent in regions that require it) personalise ads. This includes the DoubleClick DART cookie and other identifiers described at policies.google.com/technologies/ads.

We use Google AdSense (publisher ID ca-pub-1958898085199553) to display ads on the Site. Google and its certified third-party vendors and exchanges may use cookies, web beacons, device identifiers and similar technologies to serve, measure and (subject to consent where required) personalise ads based on your prior visits to this Site and other sites.

Specifically:

Google, as a third-party vendor, uses cookies to serve ads on the Site, including the DoubleClick DART cookie, which enables it to serve ads based on your visit to this Site and other sites on the Internet.
You may opt out of personalised advertising by Google by visiting Google Ads Settings.
You may opt out of a third-party vendor’s use of cookies for personalised advertising by visiting aboutads.info/choices (US), youronlinechoices.eu (EU), or optout.networkadvertising.org.
We participate in the IAB Transparency & Consent Framework (TCF v2.2) and Google’s Consent Mode v2 where required. EEA, UK and Swiss visitors are shown a consent banner the first time they visit and can withdraw consent at any time via the “Cookie settings” link in the footer.

A current list of Google’s advertising partners and their privacy policies is available at Google Ad Manager partners.

6. Legal bases for processing (EEA/UK)

If you are located in the European Economic Area, the United Kingdom or Switzerland we process personal data under one or more of the following lawful bases:

Consent — for non-essential cookies (analytics & advertising). You may withdraw consent at any time.
Contract — to respond to your contact/support requests.
Legitimate interest — to operate, secure and improve the Services, prevent fraud and abuse.
Legal obligation — to comply with applicable laws.

If you are in the EEA, UK or Switzerland, you have the right to: access your data; correct it; delete it; restrict or object to processing; data portability; and withdraw consent. You also have the right to lodge a complaint with your local data protection authority. To exercise these rights, contact hello.toolskit@gmail.com. We will respond within 30 days.

8. California privacy rights (CCPA / CPRA)

If you are a California resident, the California Consumer Privacy Act (CCPA), as amended by the CPRA, gives you the right to know what personal information we collect, the right to delete personal information, the right to correct inaccurate personal information, the right to opt out of the “sale” or “sharing” of personal information (including the use of cross-context behavioural advertising), and the right to non-discrimination for exercising your rights.

We do not sell personal information for money. We may “share” personal information with advertising partners as defined under CCPA. To opt out, use the “Cookie settings” link in the footer or enable the Global Privacy Control (GPC) signal in your browser. To exercise any other CCPA right, email hello.toolskit@gmail.com with the subject line “California Privacy Request”.

9. Other US state privacy laws

Residents of Colorado, Connecticut, Utah, Virginia, Texas and other US states with comprehensive privacy laws have comparable rights of access, deletion, correction, portability and opt-out from targeted advertising. Use the same contact and opt-out mechanisms described above.

10. International data transfers

Our infrastructure is provided by Cloudflare and may process requests at edge locations worldwide. Advertising and analytics partners may transfer data to the United States and other jurisdictions. Where required, transfers from the EEA/UK rely on Standard Contractual Clauses or equivalent safeguards.

11. Data retention

Contact-form messages are retained for up to 24 months unless deletion is requested earlier. Server access logs are retained for up to 90 days for security and abuse prevention. Aggregated, de-identified analytics may be retained indefinitely. Cookies are retained for the lifetimes set by their respective issuers (see Google’s policies for advertising cookies).

12. Security

We use administrative, technical and physical safeguards designed to protect personal information, including HTTPS/TLS across the Site, edge DDoS protection via Cloudflare, scoped administrative access and least-privilege secrets management. No method of transmission or storage is 100% secure; we cannot guarantee absolute security.

13. Children’s privacy

The Services are not directed to children under 13 (or under 16 in the EEA/UK). We do not knowingly collect personal information from children. If you believe a child has provided personal information to us, contact hello.toolskit@gmail.com and we will delete it.

14. Third-party links

The Site contains links to third-party websites and resources. We are not responsible for the privacy practices of those sites. Please review their policies before sharing information.

15. Changes to this Policy

We may update this Privacy Policy from time to time to reflect changes in our practices or for legal reasons. We will revise the “Last updated” date at the top. Material changes will be highlighted on the Site. Continued use after the effective date constitutes acceptance.
