Privacy Policy

Last Updated: May 11, 2026

1. INTRODUCTION

Rfsignal Ltd (“we,” “us,” or “our”) respects your privacy and is committed to protecting your personal data. This Privacy Policy explains how we collect, use, and safeguard your information when you visit our website (rsdapp.com) and use the RSD App software application, in compliance with the UK General Data Protection Regulation (UK GDPR).

2. DATA WE COLLECT, WHY, AND OUR LAWFUL BASIS

Because our payments are handled by our Merchant of Record (Paddle), we do not collect or process your financial data directly. However, to operate the software and prevent piracy, our application and licensing server (Keygen.sh) collect the following Personally Identifiable Information (PII). Under UK GDPR, we must establish a “lawful basis” for processing this data:

  • Email Addresses: Used to issue your license key, provide customer support, and send critical updates. (Lawful Basis: Contractual Necessity)
  • Machine Fingerprints: We collect hardware identifiers, specifically MAC addresses and/or UUIDs, strictly to validate and enforce Node-Locked and Floating license constraints. (Lawful Basis: Contractual Necessity)
  • IP Addresses: Logged for security purposes, regional localization, and license validation. (Lawful Basis: Legitimate Interests in preventing fraud and software piracy)

3. TELEMETRY, CRASH REPORTING, AND USAGE ANALYTICS

To continuously improve the stability and performance of RSD App, the application is capable of transmitting telemetry data back to our servers. (Lawful Basis: Consent)

  • Crash Reporting: If the application encounters a fatal error, it may automatically generate and send a Python stack trace to help our engineering team identify and patch the bug.
  • Usage Analytics: Anonymous data regarding which features (e.g., S-Parameters, Yield Analysis) are used most frequently to guide future development.

4. COOKIES AND WEBSITE TRACKING

When you visit rsdapp.com, we may use essential cookies to ensure the website functions correctly, manage user sessions, and securely facilitate the checkout process via our payment provider. You can instruct your browser to refuse all cookies or to indicate when a cookie is being sent.

5. YOUR RIGHT TO OPT-OUT

Under UK GDPR, you have the right to control your data:

  • Non-Essential Telemetry: You may opt out of usage analytics and crash reporting at any time by utilizing the toggle provided within the RSD App’s ‘Preferences’ menu.
  • Essential Licensing Data: The transmission of your Email, IP address, and Machine Fingerprint is strictly necessary for the software’s license verification to function. You cannot opt out of this collection while actively using a licensed copy of RSD App.

6. DATA SHARING

We do not sell your personal data. We only share data with trusted third-party processors required to run our business:

  • Paddle: Handles all e-commerce, billing, and VAT compliance.
  • Keygen.sh: Manages our cryptographic license generation and validation via API.
  • Sentry.io: Securely receives and organizes automated crash reports and error logs.

7. INTERNATIONAL DATA TRANSFERS

To provide our services, we utilize third-party processors (such as Paddle, Keygen, and Sentry) that operate servers outside of the United Kingdom and the European Economic Area (EEA), primarily in the United States. Whenever we transfer your personal data out of the UK, we ensure a similar degree of protection is afforded to it by ensuring these providers operate under approved legal frameworks, such as the UK Addendum to Standard Contractual Clauses or the EU-US Data Privacy Framework.

8. DATA RETENTION

We will only retain your personal data for as long as reasonably necessary to fulfill the purposes we collected it for. Specifically, we retain active licensing data for the duration of your software subscription. Upon expiration or cancellation, we may retain basic transaction data (such as emails and payment records) for up to 6 years to satisfy legal, accounting, and tax requirements.

9. YOUR DATA PROTECTION RIGHTS

If you are a resident of the UK or the EEA, you are granted specific rights regarding your personal data:

  • The right to request access to the data we hold about you.
  • The right to request correction of inaccurate data.
  • The right to request the deletion of your data (subject to our legal requirements to maintain certain licensing and tax records).
  • The Right to Complain: You have the right to make a complaint at any time to the Information Commissioner’s Office (ICO), the UK supervisory authority for data protection issues (www.ico.org.uk). We would, however, appreciate the chance to deal with your concerns before you approach the ICO.
