Privacy Policy

Last updated: 18 March 2026

Prescription Calculator ("we", "us", or "our") operates the website prescription-calculator.co.uk. This page explains how we collect, use, and protect your information when you use our NHS prescription prepayment certificate calculator.

Information We Collect

Our prescription calculator runs entirely in your web browser. The medication details, prescription frequencies, and cost calculations you enter are processed locally on your device and are not sent to our servers.

We do not require you to create an account or provide any personal information to use the calculator. No health or medical data is transmitted or stored by us.

Analytics

We use Google Analytics to understand how visitors use our site. This service may collect:

Pages visited and time spent on each page
Your approximate geographic location (country/city level)
Device type, browser, and operating system
Referring website or search terms

This data is aggregated and does not personally identify you. You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on.

Cookies and Local Storage

We use cookies and similar technologies for:

Essential functionality: Saving your medication list and calculation results locally on your device using browser local storage so your data is preserved between visits.
Analytics: Google Analytics uses cookies to distinguish unique visitors and track sessions.
Advertising: Google AdSense may use cookies to serve personalised advertisements (see below).

You can control cookies through your browser settings. Disabling cookies may affect some functionality, including the ability to save your calculations.

Advertising

We display advertisements through Google AdSense to support the free operation of this site. Google AdSense may:

Use cookies to serve ads based on your prior visits to this and other websites
Collect data about your interactions with advertisements
Allow third-party vendors to serve ads using cookies

You can opt out of personalised advertising by visiting Google Ads Settings or aboutads.info.

Data Security

We take reasonable measures to protect the information handled by our website. Since your calculator data stays on your device, it is protected by your own device's security measures. Our website is served over HTTPS to ensure secure communication.

Your Rights (UK GDPR)

Under the UK General Data Protection Regulation, you have the right to:

Access the personal data we hold about you
Request correction of inaccurate data
Request deletion of your data
Object to processing of your data
Data portability
Withdraw consent at any time

Since we do not collect personal data directly, most of these rights relate to data collected by third-party services (Google Analytics, Google AdSense). Please refer to Google's Privacy Policy for information on exercising your rights regarding their data collection.

Children's Privacy

Our website is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us and we will take steps to remove it.

External Links

Our site contains links to external websites, including NHS and GOV.UK resources. We are not responsible for the privacy practices of these third-party sites and encourage you to read their privacy policies.

Data Retention

We retain data as follows:

Local storage data: Stored in your browser until you clear it. We have no access to this data.
Analytics data: Retained according to Google Analytics' default retention policy (typically 26 months, anonymised).
Advertising data: Managed by Google AdSense according to their data retention policies.

Since we do not collect personal data directly, there is no personal data for us to delete from our servers.

Changes to This Policy

We may update this privacy policy from time to time. Any changes will be posted on this page with an updated "Last updated" date. We encourage you to review this policy periodically.
