Privacy Policy & Cookie Disclosure

Last updated: October 2026

Core Privacy Pledge: VAT Calculator operates on a client-side execution model. We do not require account registration, do not store financial or commercial invoice numbers on remote servers, and do not sell user personal information.

This Privacy Policy governs your use of VAT Calculator ("we", "our", or "the Platform") and explains our collection, usage, and safeguarding of data when you access our tools and educational articles.

1. Zero Remote Storage (Client-Side Mathematical Execution)

Our core sales tax and VAT algorithms run entirely inside your browser's runtime JavaScript engine. When you input net amounts, gross totals, line-item quantities, discount percentages, or freight costs, the mathematical operations execute exclusively in random-access memory (RAM) on your personal device.

We maintain zero backend application databases for storing your invoice figures. No financial figures are logged, captured, transmitted to our servers, or shared with third parties.

2. Local Storage & Calculation History

For user convenience, the calculator offers an optional "Recent Calculations" history feature. When active, snapshots of recent figures are written exclusively to your device's browser localStorage. This data never traverses the internet, and you can permanently delete it at any time by clicking the "Clear" button in the calculator interface or clearing your browser cookies and site storage.

3. Advertising Partners & Google AdSense Disclosures

To sustain free public access to our 28-jurisdiction financial calculations and research guides, we may display online advertisements served by third-party advertising partners, notably Google AdSense. In compliance with Google's Required Content for Privacy Policies and applicable privacy regulations:

Third-party cookies: Third-party vendors, including Google, use cookies and web beacons to serve advertisements based on a user's prior visits to this website or other websites across the Internet.
DoubleClick / Advertising Cookies: Google's use of advertising cookies enables it and its network partners to serve ads to users based on their browsing visits to VAT Calculator and other websites.
Personalized Advertising Opt-Out: Users may opt out of personalized advertising at any time by visiting Google Ads Settings.
Network Opt-Out: Alternatively, users may opt out of a third-party vendor's use of cookies for personalized advertising by visiting the Network Advertising Initiative or Digital Advertising Alliance opt-out portal at www.aboutads.info.

4. Consent Management & European Regulations (GDPR / UK GDPR)

If you access our site from the European Economic Area (EEA), the United Kingdom, or Switzerland, we implement a Google-certified Consent Management Platform (CMP) conforming to the IAB Europe Transparency and Consent Framework (TCF v2.2). This framework gives you explicit granular control to:

Accept or decline non-essential advertising and analytics cookies.
Manage legitimate interest selections for advertising vendors.
Modify or revoke your consent preferences at any time during your browsing session.

5. California Consumer Privacy (CCPA / CPRA) Rights

Under the California Consumer Privacy Act (CCPA) and the California Privacy Rights Act (CPRA), California residents are entitled to specific rights regarding their personal information:

Right to Know & Access: You may request disclosure of what personal data categories are processed.
Right to Delete: You have the right to request deletion of personal information held by us.
Right to Opt-Out of Sale / Sharing: We do not sell personal information for monetary compensation. You may opt out of third-party cookie-based tracking as described in Section 3 above.
Non-Discrimination: We do not discriminate against users who exercise their statutory privacy rights.

6. Log Files & Web Hosting Telemetry

Like virtually all web hosts, our hosting infrastructure (Vercel) automatically collects basic technical log data when a page request is made. This includes your Internet Protocol (IP) address, browser user-agent, operating system, referring URL, and timestamp. These logs are used strictly for diagnostic server stability, DDoS protection, and security auditing, and are never joined with user identity.

7. Modifications to This Policy

We may occasionally update this Privacy Policy to reflect technical enhancements, statutory tax legislation changes, or updated ad-network compliance requirements. Any amendments will be reflected on this page with an updated revision date.
