How We Protect Your Privacy
Four architectural decisions that make your data truly private
Client-Side Calculations
All tax calculations run in your browser using JavaScript. Your salary, tax code, and personal details never leave your device.
Zero Server Storage
We don't store your tax data on our servers. Calculations happen locally, results display instantly, nothing gets saved remotely.
Optional Analytics
Anonymous usage data (page views, device type) only with your consent. You can decline entirely - the calculator works exactly the same.
Privacy by Design
Not just policy - architectural impossibility to see your data. We built privacy into the foundation, not added it later.
Where Your Tax Data Goes
Spoiler: Nowhere. Here's the technical breakdown.
Your Device
All calculations happen here in your browser. Your salary, tax code, and personal details never leave this device.
Our Servers
Only serve the website code (HTML, CSS, JS). No tax data, no personal information, no calculation results stored.
localStorage
We save your inputs locally for convenience. This data stays on your device and can be cleared anytime.
Technical Explanation
We use client-side JavaScript to perform all tax calculations in your browser. The calculation engine runs entirely on your device - we literally cannot see your tax information even if we wanted to. This is privacy by design, not just policy.

Policy Updates
If we update this policy, we'll change the date at the top and add a notice on the site. We'll never make changes that compromise your privacy.
