Cancel by reason

CerebrumIQ has not published a mandatory process; include supporting documents and ask for confirmation of cancellation and refund if charged without service.

Applicable law: Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 when contract formed online.

Price increase

If CerebrumIQ increases the subscription price for existing customers without consent, the change may give you a right to cancel. Provide the original plan details and screenshots or invoices showing the price change. If CerebrumIQ refuses, you may rely on unfair terms principles in the Consumer Rights Act 2015.

Applicable law: Consumer Rights Act 2015.

Death of the subscriber

Provide a copy of the death certificate and the account holder name. Ask support to close the account and stop recurring charges. CerebrumIQ has not published a specific bereavement policy; use support email [email protected] and request written confirmation.

Applicable law: Not a specific statutory article but contact support and bank for charge disputes.

Legitimate grounds accepted by CerebrumIQ (refund exceptions)

Research shows CerebrumIQ lists the following refund exceptions: trial period refunds for first-time trial users, documented service unavailability longer than 24 consecutive hours, verified technical issues preventing core feature access reported within 30 days, billing errors including duplicate or unauthorized transactions, and legal requirements. Required proof documents vary by case: trial refund - evidence you are a first-time trial user and request via official channels; service downtime - screenshots, timestamps and status reports; technical issues - error logs and correspondence; billing errors - bank statements and transaction IDs.

Applicable law: Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 for online contracts; Consumer Rights Act 2015 for service quality.

If you signed up online you have a 14-day cooling-off right under the Consumer Contracts Regulations 2013.

Applicable law: Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013.

Negotiate or save

Before you cancel: how to negotiate

Research does not record specific retention offers publicly disclosed by CerebrumIQ. If you want to keep the service, contact [email protected] and ask for retention options. Example requests to make: ask for a discount, ask to downgrade to a lower tier or to receive an extended trial period. Keep all replies in writing. If you are seeking a refund instead, cite the refund exceptions such as billing errors or service downtime and attach supporting evidence.

What cancelling saves you - yearly calculation

Use the real plan prices reported by users:

Bi-weekly Subscription shown as approximately £29.90 per month. Annual cost: £29.90 x 12 = £358.80 per year.

Monthly Excellence plan price: £29.95 per month. Annual cost: £29.95 x 12 = £359.40 per year.

Example saving if you cancel Monthly Excellence: canceling saves £29.95 per month or £359.40 per year. If you switch to a free alternative such as Mensa Workout at £0, annual saving is £359.40 - £0 = £359.40 per year.

Cheapest real alternative named here is Mensa Workout at £0 per month.

What to do after cancelling CerebrumIQ

Access and final billing

After cancellation you retain access until the end of the paid billing period, according to CerebrumIQ official guidance. Check your account for an end date and for any outstanding charges. If you were charged after cancellation, gather receipts and timestamps.
