Privacy & GDPR

Privacy Policy

Last updated 2026-05-12. Plain-English summary first, full policy underneath.

TL;DR

Every calculation on SalaryGrid runs entirely in your browser. We never receive your gross salary, pension contributions, tax code or any other figure you enter. Our servers see only the usual request metadata required to deliver the HTML page (IP address, user-agent, referer) — and the only cookies we set are those required by Google AdSense to render the ads you see on the site.

1. Who we are

This site (salarygrid.uk) is operated as a free, open-source utility for UK PAYE and Scottish Income Tax modelling. For the purposes of UK GDPR and the Data Protection Act 2018 we are the data controller for any personal data we incidentally process while serving the site, including IP-derived analytics performed by our advertising partner.

You can contact us with privacy questions, data-subject access requests or complaints at privacy@salarygrid.uk. If you are not satisfied with our response you have the right to complain to the Information Commissioner's Office (ICO) at ico.org.uk.

2. What we do not collect

To be unambiguous about what does not happen on this site:

3. What we do process

3.1 Server logs (legitimate interest)

Our hosting provider — Cloudflare Pages — automatically processes request metadata to deliver the site and protect it from abuse. This includes your IP address, user-agent string, requested URL, response status and a timestamp. These logs are retained by Cloudflare under their own privacy terms and are not exported or aggregated by us. The legal basis is legitimate interest (delivering a working website and protecting it from attacks). See Cloudflare's Privacy Policy for full details.

3.2 Advertising via Google AdSense (consent)

SalaryGrid.uk shows clearly-labelled Google AdSense placements with fixed dimensions so that ads cannot push your content around the page when they load. When you visit the site, Google AdSense may set or read cookies and similar identifiers from your device for the purposes of:

The legal basis for cookies that are strictly necessary to serve the ads is legitimate interest; the legal basis for any personalisation cookies is your explicit consent, recorded via Google's Funding Choices consent banner.

You can withdraw consent or stop personalisation at any time:

Google's full data-processing terms for publishers like us are at privacy.google.com/businesses/adsservices.

3.3 Google Fonts

We load the Inter and JetBrains Mono typefaces from Google Fonts (fonts.googleapis.com and fonts.gstatic.com). Google may process your IP address when those font files are fetched. We do not pass any other personal data to Google as part of this request.

4. Cookies — full inventory

Name / pattern Set by Purpose Expiry
__gpi, __gads Google AdSense Ad selection, frequency capping, IVT detection up to 13 months
FPID, NID, IDE Google Personalised advertising (with consent) up to 24 months
FCNEC, FCCDCF Google Funding Choices Records your consent choices for the AdSense banner up to 13 months

We do not set any first-party cookies of our own. The list above is indicative — Google occasionally updates the names of its cookies; the authoritative current list is published by Google at policies.google.com/technologies/cookies.

5. Your rights under UK GDPR

Because we deliberately hold almost no personal data, most data-subject rights resolve trivially: there is nothing to access, nothing to rectify, nothing to erase, nothing to port. The rights still formally apply, and they are:

For any request, please email privacy@salarygrid.uk. We aim to respond within one calendar month.

6. International transfers

Cloudflare and Google operate globally; your request and any ad-serving traffic may be processed in jurisdictions outside the UK. Both providers rely on UK International Data Transfer Agreements (or equivalent Standard Contractual Clauses with the UK Addendum) to legitimise those transfers.

7. Children

SalaryGrid is aimed at working adults paying UK Income Tax. We do not knowingly process the personal data of children under 13. If you believe a child has interacted with the site in a way that requires intervention, please email privacy@salarygrid.uk.

8. Changes to this policy

We will update this policy when our processing changes — most likely if we add or remove an advertising partner, or if the law changes. The "Last updated" date at the top of this page is authoritative; for significant changes we will surface a notice on the home page for a reasonable period.

Architectural disclosure

All calculator math runs in JavaScript in your browser. You can verify this by opening your browser's Network panel while typing into any field — no XHR or fetch requests are made for the calculation. The site is intentionally usable offline once the page is loaded.
