Privacy Policy

Last updated: September 29, 2026

1. Data We Collect

FreeToolHub is designed with privacy by default. We collect zero personal data from our calculators and tools. All calculations happen in your browser. Your data never leaves your device.

The only data we may collect:

• Anonymized page views and aggregate usage statistics via analytics (Google Analytics 4 and Plausible)
• Standard server logs (IP anonymized after 24 hours)
• Information you voluntarily provide via our contact form

2. Cookies

We use minimal first-party functional cookies (e.g., remembering your dark-mode preference). We do not set third-party tracking cookies ourselves.

• Analytics cookies: We use Google Analytics 4 (loaded via Google Tag Manager) and Plausible. Google Analytics may set first-party cookies such as _ga to distinguish visitors and measure aggregate usage; Plausible is cookie-less. Google Analytics runs with Google Consent Mode v2, which defaults to denied — no analytics cookies are set until you accept them in our cookie banner. You can also opt out of Google Analytics across all sites with the Google Analytics Opt-out Browser Add-on.
• Functional cookies: First-party cookies used to remember preferences such as theme (dark/light mode). These are essential and cannot be disabled.

You can control and delete cookies through your browser settings. Disabling cookies may limit some features of our site but will not affect the core functionality of our tools.

Advertising cookies: this site loads Google AdSense, which may set cookies to serve ads. See section 3 for what Google may collect and how to opt out.

3. Advertising & Google AdSense

FreeToolHub uses Google AdSense to serve advertising on this site. Google AdSense is a third-party advertising vendor that uses cookies to serve ads to users based on their visits to this site and other sites on the Internet.

How Google AdSense works:

• Google uses cookies (including the DoubleClick DART cookie) to serve ads based on your prior visits and interests.
• These cookies allow Google and its partners to display ads that are relevant to your interests.
• Third-party vendors and Google may use information (not including your name, address, email, or phone number) about your visits to this and other websites to provide advertisements about goods and services of interest to you.
• Users may opt out of personalized advertising by visiting Google Ads Settings.
• Users may also opt out of third-party vendors' use of cookies for personalized advertising by visiting www.aboutads.info/choices.

Consent: advertising and analytics cookies are loaded through Google Consent Mode v2, which defaults to denied — no advertising cookies are set until you accept them in our cookie banner. If you are in the European Economic Area (EEA), UK, or Switzerland, Google will only use consented advertising cookies in accordance with GDPR.

Important: All tools on FreeToolHub process data entirely in your browser. Advertising cookies do not have access to the data you enter into our tools — they only track page visits and ad interactions.

4. Your Rights (CCPA / GDPR)

• EU/UK residents: Right to access, rectify, delete data
• California residents: Right to know, delete, opt-out of sale
• Contact us at privacy@freetoolhub.org to exercise these rights

5. Data Security

All data transmission is encrypted via HTTPS/TLS 1.3. We do not store any user-input data on our servers.

6. Children's Privacy

This site is not directed at children under 13. We do not knowingly collect data from children.

7. Voluntary Tips & Donations

This site accepts voluntary tips and donations via third-party platforms such as Ko-fi. When you choose to support us:

• Payment processing is handled entirely by the third-party platform (e.g., Ko-fi, Stripe). We do not directly collect or store your payment card details.
• Information collected during payment (such as your name, email, and payment amount) is used only for processing the transaction, issuing receipts, and tax reporting as required by law.
• We will never send you marketing emails or share your payment information with third parties for promotional purposes.

8. Sponsored & Affiliate Content

Some links on this site are affiliate or sponsored links. This means we may earn a commission if you click on a link and make a purchase — at no extra cost to you. All sponsored and affiliate content is clearly labeled with a "Sponsored" tag or "Affiliate" designation. These partnerships do not influence our tool recommendations or editorial integrity.

9. AI-Assisted Content

Some content on this site — including guides, tool descriptions, and help text — was created with the assistance of AI tools and reviewed and edited by humans. AI-generated outputs (such as paraphrased text, email drafts, or resume rewrites) are produced by client-side models and are not stored on our servers. We strive for accuracy, but AI-generated content may occasionally contain errors — always verify important information independently.

10. Disclaimer

The tools on this site are for informational purposes only. They are not legal, tax, or financial advice. Always consult a licensed professional before making financial or legal decisions.

11. MCP Server & AI Assistant Privacy

FreeToolHub operates an MCP (Model Context Protocol) Server that allows AI assistants like Claude and ChatGPT to use our calculation tools on your behalf. When an AI assistant calls our MCP Server:

• Only calculation parameters are transmitted (e.g., income amount, tax year, filing status) — never personal identity data
• Results are returned instantly and are not stored or logged on our servers
• Rate limiting uses an anonymized IP hash that resets daily — no permanent IP records are kept
• The AI assistant you use may have its own privacy policy governing how it handles the calculation results
