Cancel by reason

Moving abroad or to a different jurisdiction

If you are moving and cannot use the service in your new jurisdiction, send a cancellation request with proof of move such as a utility bill or tenancy agreement showing the new address. Cerebrum IQ Test does not publish a specific policy for moves; rely on your contract and the 14-day cooling-off right if within that period. Applicable law: Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013.

Price increase

If Cerebrum IQ Test increases the subscription price mid-contract without your express consent, UK consumer law allows you to reject the change and treat the contract as terminated. Provide the price increase notice and your subscription statement as proof. Applicable law: Consumer Rights Act 2015 and Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013.

Death of subscriber

To cancel for the death of the subscriber, send a cancellation request from the executor or next of kin with a copy of the death certificate and proof of identity. Cerebrum IQ Test does not publish a specific bereavement process; legal right to terminate depends on contract terms and local law. Applicable law: Consumer Rights Act 2015.

Service unavailability or technical failure

Cerebrum IQ Test lists service unavailability and platform bugs that prevent access as refund exceptions. To claim termination or refund, provide screenshots, timestamps, and any correspondence showing repeated failures within 30 days of occurrence. Applicable law: Consumer Rights Act 2015.

Billing errors and unauthorised charges

Cerebrum IQ Test accepts billing errors and unauthorised transactions as exceptions for refund. Provide bank statements, transaction IDs and any communication with the company. Also contact your card issuer to request chargeback or Section 75 where applicable.

Cooling-off period (14 days)

For contracts concluded online, you have a 14-day cooling-off right under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013. If you have expressly asked Cerebrum IQ Test to start performance of digital content or services during the 14-day period and acknowledged loss of the right, the cooling-off right may not apply. Provide the sign-in timestamp and any acceptance screen as proof. Applicable law: Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013.

Negotiate or save

Before you cancel - negotiate

Cerebrum IQ Test has no widely reported retention offers in the research. When you contact support, ask explicitly for a retention offer - for example a discounted monthly rate, a pause on billing, or a free extension of the trial. Script to use: state your reason to cancel, ask if a discounted rate or a pause for 1 to 3 months is available, and request the offer in writing. Keep any written offer as proof.

What cancellation saves you - yearly calculation

Use actual plan prices to measure savings. Monthly Excellence plan: £29.95 x 12 = £359.40 per year. Bi-weekly Subscription listed with monthly equivalent £29.90 x 12 = £358.80 per year. Example saving if you switch to a competitor at £11.99/month: £29.95 - £11.99 = £17.96 saved per month; yearly saving = £17.96 x 12 = £215.52.

Real example of costs reported by customers: recurring charges of £29.99 were raised in customer complaints. One reviewer reported total loss of £209.93 due to repeated monthly charges.

Cheapest real alternative (example): Lumosity at £11.99 per month (monthly price used for comparison). This alternative reduces annual spend to £11.99 x 12 = £143.88.

What to do after cancelling Cerebrum IQ Test

Check access and final billing

After cancellation, service continues until the end of the current paid period. Verify the final billing date in your account and keep a copy of the cancellation confirmation. If you see further charges after the confirmed end date, save bank statements and contact support immediately.

Ask for data and account closure

Request deletion of personal data or account closure in writing to [email protected]. Keep copies of your request and any replies. If you need your test results, download them before requesting deletion.

Re-activation and refunds

If you later re-subscribe, Cerebrum IQ Test will treat it as a new subscription. Regular subscriptions are generally not eligible for refunds; trial refunds (trial cost $1.00) are eligible for a full refund within 30 days for first-time trial users who meet the trial refund conditions. For refund disputes, use the escalation steps in the legal protections section.

Next steps and practical checklist

Follow this checklist to cancel and protect yourself.

  • Sign in to the self-service portal and cancel via the 6-digit verification flow; take screenshots of confirmation.
  • Send a cancellation email to [email protected] requesting confirmation and final billing date; keep the sent email and any reply.
  • If you suspect unauthorised charges, save bank statements showing the charges and use your card issuer's chargeback or Section 75 process.
  • If you used a trial, request a trial refund within 30 days if eligible and you are a first-time trial user.
  • If necessary, send a registered letter to: Cerebrum IQ Test, 30 N Gould St Ste R, 82801 Sheridan, USA and keep proof of posting.
  • If cancellation fails or you are charged after cancellation, escalate to Citizens Advice and your local Trading Standards, and consider contacting the CMA.
