Cancel by reason

Cooling-off period (14 days)

If you bought a subscription online, you have a 14-day cancellation right under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013. The right starts when the contract is concluded. If you ask for the service to start during the 14-day period and you gave express consent that you lose your right to withdraw, the right to a refund is lost for the period the service was supplied. See the legislation: Consumer Contracts Regulations 2013.

Required proof documents: purchase confirmation, order number, date of purchase.

Technical problems or defective digital content

The Wonder Weeks official refund page states refunds are not standard but technical problems that cannot be resolved may qualify for a refund on a case-by-case basis. For Google Play or Apple purchases, store refund policies also apply. See Official refund FAQ.

Required proof documents: detailed description of the technical problem, screenshots, device information and any support correspondence.

Price increase

If Wonder Weeks raises the subscription price during a fixed-term commitment and does not offer a right to exit in the terms, UK consumer law may treat an extra-large unilateral price increase as an unfair term under the Consumer Rights Act 2015. You should contact support and request cancellation and a refund if you did not agree to the increase.

Required proof documents: notice of price increase and payment receipts.

Death of the subscriber

For personal digital services, death of the subscriber typically ends the consumer relationship. Contact [email protected] and provide the death certificate and proof of account ownership to request account closure. Applicable law: Consumer Rights Act 2015 for contract fairness.

Required proof documents: death certificate, account details, proof of relationship if needed.

End of commitment or automatic expiry

24-month packages automatically stop after 24 months and do not need action to terminate. One-month and three-month subscriptions require manual cancellation to prevent renewal. See the official cancellation page: How to cancel.

Required proof documents: subscription ID or receipt.

Negotiate or save

Before cancelling: negotiate

The public information contains no reported retention offers from Wonder Weeks. If you want to ask for a discount or a change of plan, contact [email protected] and request a longer-term plan or a different in-app purchase. State your current plan, device platform and order number in the message.

What cancelling saves - concrete calculation

Use these published prices to calculate yearly cost differences.

Example calculation using published plan prices:

  • 1 month subscription at £3.99 x 12 = £47.88 per year.
  • 24 months subscription price_monthly £1.25 x 12 = £15.00 per year.
  • Yearly saving if you move from £3.99 monthly to £1.25 monthly equivalent: £47.88 - £15.00 = £32.88 per year.

Cheapest real competitor from the research: KidsGram at £9.00 per month. Annual comparison: KidsGram £9.00 x 12 = £108.00 per year.

What to do after cancelling Wonder Weeks

Check access and final billing

After cancellation the paid membership remains valid until the end of the current paid period. Confirm the end date in your app store subscription page or in any confirmation email you receive.

Data and account

If you want your data deleted or account closed, contact [email protected] and request account deletion. Keep a copy of any reply as proof.

Re-activation

You can re-subscribe at any time by purchasing a new in-app subscription through your device store. If you previously purchased a one-time app, contact support to confirm continued access.

Next steps and practical checklist

Follow this checklist to cancel and protect yourself.
