Privacy Policy

1. Who We Are

UK Take-Home Pay Calculator is operated by UK Calculator Matrix, an independent project based in the United Kingdom. We are not affiliated with HMRC, the Student Loans Company, or any government body.

For privacy enquiries, contact us via the feedback page.

2. What Information We Collect

We collect minimal information. The types of data we may process are:

• Usage data: anonymised page views, session duration, and browser type via analytics (see Section 5). This data cannot identify you personally.
• Feedback submissions: if you submit a message via our feedback form, we collect the content of that message and any contact details you voluntarily provide.
• Technical data: IP address (anonymised), browser type, and referring URL — collected automatically by our hosting provider's server logs.

We do not collect: your salary, tax code, pension details, student loan plan, National Insurance number, date of birth, or any other financial information you enter into the calculator.

3. Calculator Data — How It Works

This is our most important privacy commitment. The calculator is a client-side application — all computation runs in your web browser using JavaScript. When you enter your salary, student loan plan, pension contributions, or any other figure:

• The data stays in your browser's memory only.
• No data is sent to our servers or any third-party servers.
• When you close or refresh the page, all entered data is discarded.
• Nothing is stored in cookies, localStorage, or any persistent browser storage.

You can verify this by inspecting your browser's network requests (DevTools → Network) while using the calculator. You will see no outbound data requests triggered by your inputs.

4. Cookies

We use a minimal cookie footprint:

• Essential cookies: our hosting provider may set a session cookie necessary for delivering the website. These do not contain personal data.
• Analytics cookies: if you consent, we set a first-party analytics cookie to measure traffic. This is anonymised and does not identify individuals (see Section 5).

We do not use advertising cookies, tracking pixels, or third-party marketing cookies of any kind. You can disable cookies in your browser settings without affecting the calculator's functionality.

5. Analytics

We use privacy-focused, anonymised analytics to understand how people use the site — for example, which pages are visited most often and what devices are commonly used. This data helps us improve the calculator.

Our analytics provider is configured to: anonymise IP addresses before storage, not use cross-site tracking, not share data with advertising networks, and retain data for a maximum of 14 months before deletion.

Aggregate analytics data cannot be used to identify individual visitors.

6. Third Parties

The following third-party services are used to deliver the website. Each has its own privacy policy:

• Google Fonts (fonts.googleapis.com): used to load the Inter typeface. Google may log your IP address when the font is requested. Google Privacy Policy.
• Tailwind CSS CDN (cdn.tailwindcss.com): used for styling. The CDN provider may log request metadata.
• Chart.js CDN (cdn.jsdelivr.net): used for interactive charts. jsdelivr may log request metadata.

We do not embed social media widgets, advertising networks, or cross-site tracking scripts.

7. Your Rights Under UK GDPR

Under UK GDPR and the Data Protection Act 2018, you have the right to:

• Access — request a copy of any personal data we hold about you.
• Rectification — request correction of inaccurate data.
• Erasure — request deletion of your data ("right to be forgotten").
• Restriction — request that we limit how we use your data.
• Portability — receive your data in a structured, machine-readable format.
• Object — object to processing of your data in certain circumstances.
• Withdraw consent — where we process data based on your consent, you may withdraw it at any time.

Given that we collect very little personal data and none of it relates to your calculator inputs, most rights requests will result in confirmation that we hold no relevant personal data. To exercise any right, contact us via the feedback page.

You also have the right to lodge a complaint with the Information Commissioner's Office (ICO) at ico.org.uk.

8. Data Retention

We retain data only as long as necessary:

• Feedback messages: retained for up to 12 months, then deleted.
• Server logs: retained for up to 90 days for security and troubleshooting, then automatically purged.
• Analytics data: retained in aggregated, anonymised form for up to 14 months.

9. Security

The website is served exclusively over HTTPS with TLS encryption. We take reasonable technical and organisational measures to protect against unauthorised access. However, no internet transmission is completely secure, and we cannot guarantee absolute security.

10. Children

This website is not directed at children under the age of 13. We do not knowingly collect personal data from children. If you believe a child has submitted information to us, please contact us and we will delete it promptly.

11. Changes to This Policy

We may update this privacy policy periodically — for example, when tax year changes affect our third-party service usage or when new legal requirements apply. The "Last updated" date at the top of this page reflects the most recent revision.

Material changes will be noted on the homepage for 30 days after publication.

12. Contact

For any privacy-related questions, data subject access requests, or concerns, please use our feedback form. We aim to respond to all enquiries within 30 days.
