How PayBreakdown handles calculator inputs, browser storage, cookies, analytics and advertising. There are no accounts and no personal details are collected.
PayBreakdown is a set of UK salary and tax calculators. There is no sign-up, no login, and no personal profile. This policy explains the three places data can go: your own browser, the calculation endpoint that returns a result without storing it, and Google's analytics and advertising tags.

PayBreakdown is a UK salary, tax and take-home pay calculator website. For privacy questions, data requests or deletion requests, contact support@paybreakdown.co.uk. We are the data controller for the limited data described below.
The calculators are deliberately built so that they never need to identify you. There is no field anywhere on the site for the following, and we ask that you do not enter them:
If you use the salary calculator's saved setups, the values are stored on your own device using browser storage, with IndexedDB used where available and browser-side encryption applied where the Web Crypto API is supported. This data is never uploaded to us. It covers calculator settings only: pay amounts and frequency, hours, pension method and rate, tax code, region, tax year, student loan plan, job labels, and up to three sets of person initials used to tell earners apart. You can delete all of it at any time from the cookie and storage control in the footer, or by clearing site data in your browser.
When comparing two or three earners the calculator asks for initials, capped at three letters, and falls back to labels such as Person 1 if you leave them blank. Full names are not accepted and are not stored. This keeps household comparison useful without the site ever holding something that identifies a real person.
Calculations run on our API. Your browser sends only the figures needed for the estimate: annual or hourly pay, bonus, other income, pension amount or rate, tax year, region, tax code, pension method, student loan plan and postgraduate loan selection. The endpoint returns the result and does not write those requests to any database. They are not linked to you, because nothing identifying you is sent with them.
Essential storage covers your cookie choice and any calculator setups you save. Google Analytics and Google AdSense are loaded with Consent Mode defaults set to denied, so advertising and analytics storage stay off until you make a choice. AdSense may use cookies, local storage, device identifiers and ad signals once you allow it, and Google may use them to personalise ads. You can change or withdraw your choice at any time from the cookie and storage control in the footer. We do not send salary figures, tax codes or any calculator inputs to Google Analytics or to advertising.
This site is free to use and is funded by advertising. Ad slots are labelled and kept visually separate from calculator results so an advert is never mistaken for a calculated figure. Adverts are not shown on the pages where you enter your own figures until after a result has been produced, and they are never placed inside a results panel.
The API applies JSON body limits, rate limits on calculation requests, CORS origin checks, a content security policy, and standard security headers. Technical access logs are created by hosting and reverse-proxy services so the site can be operated and protected; these contain IP addresses and request paths, not calculator inputs.
We hold no user records to retain, because there are no accounts. Data saved in your browser stays on your device until you clear it, and hosting access logs are rotated by the hosting provider on its standard schedule.
Because we do not hold personal data about identified users, most access and deletion requests are satisfied by clearing site data in your own browser. If you believe we hold personal data about you, contact support@paybreakdown.co.uk and we will respond. You can also complain to the UK Information Commissioner's Office if you are unhappy with how a request is handled.
This page supports the calculators by explaining the operating position behind them. Read it alongside the relevant calculator output when you need to understand assumptions, limits, contact options, privacy choices, source checks, advertising separation, or terms of use.
Trust and policy pages explain how PayBreakdown works, but they do not replace official guidance, employer or payroll records, lender documents, legal advice, tax advice, debt advice, financial advice, or a formal data-rights response where one is required.
If this page affects a calculation choice, compare it with the current tax year, source date and methodology notes used by the relevant calculator. If it affects privacy, advertising or data-rights choices, use the named contact option and avoid sending salary details you do not need to share. PayBreakdown holds nothing on a server: calculations run in your browser, and a saved setup stays in that browser only. For important decisions, keep a copy of the relevant calculator result, source date and assumptions so you can compare them with updated guidance later. Recheck this page after major product, advertising or calculation changes.
