Privacy Policy

Last updated: 1 July 2026

RisingEdge.pro ("we", "us", "our") is operated by VANTABYTE LTD, a company registered in England & Wales (company number 15622244), registered office 20 Wenlock Road, London, England, N1 7GU. We are the data controller for the personal data described in this policy.

This policy explains what personal data we collect, why, and your rights under the UK GDPR and the Data Protection Act 2018.

1. Data we collect

  • Account data — email address, username, and (for password accounts) a hashed password. If you sign in with Google or GitHub, we receive your email and basic profile from that provider.
  • Learning data — your progress, submitted HDL code, simulation/synthesis runs, bookmarks, and challenges you create.
  • Payment data — when you subscribe to Pro, payment is processed by Paddle, who act as the merchant of record. We do not receive or store your full card details; we store only a customer/subscription reference and your subscription status.
  • Communications — messages you send us (e.g. the contact form or feedback) and related correspondence.
  • Technical data — IP address, browser type, and request logs, used to operate and secure the service.

2. How and why we use your data (lawful bases)

  • To provide the service (accounts, lessons, running your code, saving progress) — performance of a contract.
  • To process subscriptions — performance of a contract (via Paddle).
  • To secure and maintain the service (rate limiting, abuse prevention, error diagnostics, logging) — legitimate interests.
  • To respond to your messages — legitimate interests.
  • To send service emails (email verification, password reset, important account notices) — performance of a contract / legitimate interests.

3. Cookies

We use only strictly necessary cookies — for example, to keep you signed in. These do not require consent. Our analytics are self-hosted and cookieless, so we do not use tracking or advertising cookies and show no cookie banner.

4. Who we share data with

We use the following processors to run the service. They process data on our instructions:

  • Paddle — payment processing (merchant of record) and invoicing.
  • Resend — sending transactional email.
  • Cloudflare — DNS, inbound email routing, and bot protection.
  • Hetzner — hosting (servers located in the EU).
  • Sentry — application error tracking.

We do not sell your personal data.

5. International transfers

Our servers are hosted in the EU (Hetzner). Transfers between the UK and EU are covered by the UK's adequacy regulations. Where a processor transfers data outside the UK/EU, appropriate safeguards (such as the UK International Data Transfer Agreement or addendum) apply.

6. Retention

We keep account and learning data for as long as your account is active. If you close your account or ask us to delete it, we delete or anonymise your personal data within a reasonable period, except where we must retain limited records to meet legal obligations (for example, tax records relating to payments).

7. Your rights

Under UK data protection law you have the right to access, rectify, erase, restrict, or object to our processing of your personal data, and the right to data portability. To exercise any of these, email contact@risingedge.pro.

VANTABYTE LTD is registered with the Information Commissioner's Office (ICO), registration reference ICO:00014629811. You also have the right to complain to the ICO at ico.org.uk if you are unhappy with how we handle your data, though we'd appreciate the chance to put things right first.

8. Children

The service is not intended for anyone under 16. We do not knowingly collect personal data from children under 16.

9. Security

We protect your data with measures including encrypted connections (HTTPS), hashed passwords, access controls, and isolated, sandboxed execution of submitted code. No system is perfectly secure, but we take reasonable steps to protect your data.

10. Changes to this policy

We may update this policy from time to time. We'll change the "Last updated" date above and, for material changes, notify you by email or an in-app notice.

11. Contact
