Privacy Policy

Last Updated: 14.02.2026

Introduction

RadWise Limited (trading as "RadWise") is committed to protecting and respecting your privacy. This Privacy Policy explains what personal data we collect from you, how we use it, and your rights in relation to that data when you use our website ("the Service").

1. Data Controller

For the purpose of the UK General Data Protection Regulation (UK GDPR), the data controller is RadWise Limited. You can contact us via our Contact Us page or at our registered office address listed in our Terms of Service.

2. What Information We Collect

We may collect and process the following data about you:

• Account Information: When you register, we collect your username, email address, and an encrypted version of your password.
• Subscription Information: If you purchase a subscription or paid feature, our payment processor (Stripe) will collect your payment card information. We do not store your full card details on our servers. We only store a record of the transaction and subscription status.
• Usage Data: We collect data about your interactions with the Service, such as the questions you answer, your performance scores, features you use (e.g., "Ask AI"), and suggestions you submit.
• Technical Data: We may collect your IP address, browser type, and operating system for security purposes and to improve our service. We may generate and store a digital 'fingerprint' of your browser/device to prevent account sharing and ensure the security of the Service.
• Security & Device Data: To ensure the security of our platform and enforce our single-user license policy, we collect technical data including your IP address, browser type, and a unique device fingerprint. This data is used strictly to detect account sharing and fraudulent activity.
• Communications: If you contact us, we will keep a record of that correspondence.
• Ask AI Data: Data input into the 'Ask AI' feature is processed by a third-party AI provider.

3. How We Use Your Information

We use the information we collect for the following purposes:

• To provide, maintain, and improve the Service.
• To create and manage your account and subscription.
• To process your payments securely through our payment processor, if applicable.
• To provide you with performance analytics and track your learning progress.
• To communicate with you about your account or important service updates.
• To ensure the security of our platform and prevent fraudulent activity.
• To prevent fraud and abuse we use device data and IP addresses to monitor for concurrent logins and account sharing, which violates our Terms of Service.
• To comply with our legal obligations.

4. Lawful Basis for Processing

Under UK GDPR, we rely on the following lawful bases to process your personal data:

• Contract: Processing your data is necessary for us to perform the contract we have with you (i.e., to provide you with the Service you have registered for, including during your free trial and any subsequent paid access).
• Legitimate Interests: We process some data for our legitimate interests, such as for security monitoring and service improvement, provided these interests are not overridden by your rights.

5. Data Sharing and Third Parties

We do not sell your personal data. We only share it with trusted third parties who are essential for providing our Service:

• Payment Processor: If you make a purchase, we use Stripe to process payments. Your payment information is provided directly to Stripe and is subject to their privacy policy.
• AI Service Provider: When you use the "Ask AI" feature, the text of the relevant quiz question and your follow-up query are sent to our AI provider (Google) to generate a response.
• Email Provider: We use a third-party service to send transactional emails (e.g., password resets).
• Third Party Providers Data: Some of our third-party service providers (e.g., Google, Stripe) may process data outside the United Kingdom or EEA. Where this occurs, we ensure appropriate safeguards are in place, such as International Data Transfer Agreements (IDTAs).
• Product Analytics: We use PostHog to understand how users interact with our Service. PostHog captures data such as pages visited, clicks, mouse movements, and technical device details. We use this to improve the user experience and fix bugs. PostHog stores data in the European Union.

6. Data Security

We take appropriate technical and organisational measures to protect your personal data against unauthorised access, loss, or destruction. However, no method of transmission over the Internet is 100% secure.

7. Data Retention

We will retain your personal data for as long as your account is active or as needed to provide you with the Service. We may also retain data for a longer period to comply with legal obligations or resolve disputes.

8. Your Rights

Under UK GDPR, you have the following rights regarding your personal data:

• The right to be informed about how your data is used.
• The right to access the personal data we hold about you.
• The right to have incorrect data rectified.
• The right to have your data erased (the "right to be forgotten").
• The right to restrict the processing of your data.
• The right to data portability.
• The right to object to the processing of your data.

To exercise any of these rights, please contact us.

9. Cookies

We use cookies to distinguish you from other users of our Service. This helps us to provide you with a good experience and allows us to improve our site.

• Strictly Necessary Cookies: Required for the operation of our website (e.g., logging in, security fingerprinting).
• Analytical/Performance Cookies: We use PostHog to recognise and count the number of visitors and see how visitors move around our website (including session replays). We only use these cookies if you have given your consent.
