Which Is Cheaper is a simple price comparison tool designed to help shoppers in the United Kingdom compare prices per unit. We are committed to protecting your personal information and being transparent about how we use it.
We do not collect personal information that directly identifies you. The calculator works entirely within your browser — the prices and numbers you enter are never sent to our servers. With your consent, we may use third-party services (see Section 6) that collect anonymous, aggregated data such as basic website usage statistics and information about how ads perform, to help us improve the service and keep it free.
Any anonymous data collected is used to: improve website functionality, fix bugs, and understand how visitors interact with our website. We do not sell, trade, or rent your personal identification data to others.
Since all calculations happen locally on your device, your input data never leaves your browser. We implement appropriate security measures to protect our website and any anonymous data that we may collect.
If you are based in the UK or EU, you have the right to request access to, correction of, or deletion of any personal data that we hold. Since we store almost no personal data, simply clearing your browser cookies will remove any locally stored preferences.
To keep this tool free, we display advertisements and measure website usage through the following third-party services. These services may place cookies or similar technologies on your device only after you have given your consent via the cookie banner on our homepage. You can withdraw your consent at any time by clearing your browser cookies and storage for this site.
These third-party vendors may use cookies to serve ads based on your previous visits. We do not provide any personally identifiable information to them.
If you consent to advertising cookies, Google may personalise the ads you see. If you decline, ads will still appear but they will be less relevant to you. You can control or opt out of personalised advertising at any time:
