Official cancellation guidance is available in the vendor help centre: Subscription cancelation and help.

Cancel by reason

Cooling-off (change of mind within 14 days)

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).

Price increase

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.

Defective service or failing to provide the promised service

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.

Death of subscriber

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).

End of commitment

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.

Moving / change of circumstances

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).

Negotiate or save

Before cancelling: negotiate

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.

What cancelling saves you - example math

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.

Cheapest real alternative named in customer feedback: CopyLeaks is mentioned by reviewers as a comparison. Check CopyLeaks pricing on their site for exact current GBP prices before switching.

What to do after cancelling Undetectable AI

Check final billing and refunds

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.

Access to data and credits

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.

Re-activation and account closure

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.

Next steps and practical checklist

Follow this checklist to cancel and preserve your rights.

  • Step 1 - Locate account email, invoice and last 4 digits of payment card.
  • Step 2 - Choose cancellation method. For strongest proof use registered postal mail to: Undetectable AI, Crown Way, CF14 3UZ Cardiff, United Kingdom.
  • Step 3 - If cancelling within 14 days, state you are exercising your cooling-off right under the Consumer Contracts Regulations 2013.
  • Step 4 - Keep proof: registered post receipt, sent emails, screenshots, and any support replies.
  • Step 5 - If charged after cancellation, raise a dispute with your card issuer and consider Section 75 or chargeback for qualifying transactions.
  • Step 6 - If refund refused, escalate to Citizens Advice and consider reporting to the Competition and Markets Authority if terms are unclear or unfair.
