Terms of Use

Last updated 11 November 2026

These terms apply to the Spark app and this website, provided by Cyber Phoenix Ltd. By using Spark you agree to them, together with Apple's standard licensed application end user licence agreement.

What Spark is

Spark is a brain-training app of short games and calm tools. It is not a medical device or medical treatment. It does not diagnose, treat, cure or prevent ADHD or any other condition, and it does not replace advice from a doctor or other qualified professional. Keep taking any treatment you have been prescribed.

Spark Plus subscriptions

  • Spark Plus is available as an annual subscription, a monthly subscription or a one-time lifetime purchase. Prices are shown in the app before you buy and may vary by country.
  • The annual plan may include a free trial. If you do not cancel at least 24 hours before the trial ends, it converts to a paid subscription and you are charged.
  • Payment is charged to your Apple ID at confirmation of purchase.
  • Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the end of the period.
  • You can manage and cancel subscriptions in your App Store account settings. Cancelling stops future renewals; you keep access until the end of the period you paid for.
  • Introductory or discounted offers apply only where shown and only to eligible users.
  • Refunds are handled by Apple under its policies. Request one at reportaproblem.apple.com.

Using Spark

Use Spark for your own personal, non-commercial use. Don't copy, modify, reverse engineer or resell the app or its content. Take breaks if you feel tired, and stop if a game causes discomfort.

Our liability

We work hard to keep Spark running well, but we provide it "as is" and cannot promise it will always be available or error free, or that you will see any particular result. To the extent the law allows, we are not liable for indirect or consequential loss. Nothing in these terms limits liability that cannot be limited by law, or your statutory rights as a consumer.

Changes

We may update these terms. The date above shows the latest version. Continuing to use Spark after a change means you accept it.

Law and contact

These terms are governed by the laws of England and Wales. Questions: support@sparkadhd.app.
