Official cancellation guidance is available in the vendor help centre: Subscription cancelation and help.
Rule: Under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 you have a 14-day cooling-off period for online distance contracts. To exercise it, notify the trader with a clear statement of cancellation and keep proof of sending.
Required proof documents: copy of cancellation message (email or letter) and evidence of posting or sending.
Applicable law: Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 (text).
Rule: If the subscription price is increased mid-term and the change is not in your contract, you can cancel and seek a refund for future periods. Provide the announcement or invoice that shows the increase.
Required proof documents: copy of price-change notification from Undetectable AI and your previous price evidence.
Applicable law: Consumer Rights Act 2015 - services must be performed with reasonable care and skill.
Rule: If the service is not provided with reasonable care and skill, you can require repeat performance or a refund under the Consumer Rights Act 2015. Research shows reports of defective output and refused refunds; gather evidence.
Required proof documents: examples of defective output, support correspondence, timestamps.
Applicable law: Consumer Rights Act 2015.
Rule: Notify the trader and provide proof of death to request account closure and refund for unused periods. Required proof documents: death certificate and proof of authority (executor details).
Rule: If your contract included a fixed minimum term and that term ends, you may stop renewal by cancelling before renewal date using one of the allowed methods. Required proof documents: copy of contract or invoice showing end date.
Rule: Moving alone is not an automatic legal ground to terminate a digital subscription; if service cannot be provided in the new jurisdiction, provide proof such as a change of address and ask the trader to terminate the contract.
Required proof documents: proof of new address (utility bill or tenancy agreement).
Retention tactics reported: research shows Undetectable AI may not publicly advertise retention offers; Trustpilot feedback describes customer service that is sometimes responsive and sometimes refusing refunds. When you contact support, request specific retention offers in writing: a discounted monthly rate, a freeze of auto-renewal, or partial refund. Example script: "I want to cancel. Before I do, can you offer a discounted rate or pause my subscription for X months? Please confirm any offer in writing." Save the written offer.
Reported charges: one customer reported being charged nearly £140. Another reported a $60 annual charge (reported in research). Converted example: $60 equals approximately £48 (converted at an illustrative rate). If you avoid one annual charge of £48, saving is: 1 x £48 = £48 per year. If you avoid an annual charge of £140, saving is: 1 x £140 = £140 per year.
Example computation for a presumed monthly plan: if a plan costs £9.99 per month, annual cost = £9.99 x 12 = £119.88 per year. If you cancel and choose a cheaper competitor at £7.99 per month, annual cost = £7.99 x 12 = £95.88 per year, saving = £119.88 - £95.88 = £24.00 per year.

The Consumer Rights Act 2015 requires digital services to be provided with reasonable care and skill. The Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 give a 14-day cooling-off right for online distance contracts, with a refund obligation.
The Competition and Markets Authority treats hard-to-cancel subscriptions and unclear auto-renewal terms as potential unfair practices. If a firm makes cancellation unduly difficult or fails to provide clear renewal notices, you can escalate the complaint.
Step 1 - complain to the trader in writing and keep evidence. Step 2 - if unresolved, contact Citizens Advice for guidance and the relevant ombudsman depending on the sector. Step 3 - consider bank chargeback for card payments or Section 75 for qualifying credit card transactions.
Official references: Consumer Contracts Regulations 2013 text and cooling-off rights overview legislation.
Action: Check your bank or card statement for charges after cancellation. If you believe you were wrongly charged, ask for a written explanation and request a refund in writing. If you used a trial and were charged, keep the trial signup confirmation and cancellation proof.
Action: Download any content you need before cancellation. Research indicates that if you cancel before the end of the subscription you may lose credits immediately; keep evidence of your remaining credits and invoices.
Action: If you later re-subscribe, confirm whether old credits and history are restored. Request account deletion if you want personal data removed and keep the vendor's confirmation of deletion.
Follow this checklist to cancel and preserve your rights.
