Cancel by reason

Moving abroad or relocation

If your move prevents use of the service you should contact [email protected] with proof of new address such as a tenancy agreement or utility bill. The company has not published a specific policy for relocation refunds; include documentary proof in your request.

Applicable law: Consumer Rights Act 2015 for service performance.

Price increase

If Caktus AI raises the price for your existing subscription you may cancel the contract and request details of changes. Provide the notice you received and the date the price change was applied. If the company applied a price increase without adequate advance notice, you may cancel under the contract terms and the Digital Markets, Competition and Consumers Act 2024 renewal provisions.

Applicable law: Digital Markets, Competition and Consumers Act 2024.

Death of subscriber

To cancel for reason of death, contact [email protected] and include a copy of the death certificate and the account holder details. Caktus AI has not published a formal bereavement policy; priority is documentary proof to support a cancellation and refund request if applicable.

Applicable law: Consumer Rights Act 2015 for contract termination reasons.

Legitimate grounds accepted by Caktus AI (billing errors and unauthorized charges)

Research shows Caktus AI states it does not normally provide refunds because it supplies non-tangible, irrevocable services, but exceptions exist for billing errors and unauthorized charges. To dispute, collect bank or card statements and correspondence and send these to support. If Caktus AI accepts an error, they have issued one-off refunds in individual cases.

Applicable law: Consumer Contracts Regulations 2013 and Payment Services rules for unauthorized charges.

End of commitment or subscription period

If you are at the end of a monthly or annual period cancel before the next billing date using the dashboard, App Store or Play Store. For annual plans, cancellation must be made before renewal to avoid the next annual charge.

Applicable law: Digital Markets, Competition and Consumers Act 2024 (renewal cooling-off rights) and Consumer Contracts Regulations 2013 (14 day initial cooling-off where applicable).

Cooling-off and trial cancellations

For a paid subscription bought online you have a 14 day right to cancel under the Consumer Contracts Regulations 2013, but digital content exceptions apply where you consent to immediate access. If you took a promotional trial and were billed, request cancellation via the dashboard or App Store and preserve timestamps and screenshots.

Applicable law: Consumer Contracts Regulations 2013; Digital Markets, Competition and Consumers Act 2024.

Negotiate or save

Before you cancel - negotiate

Caktus AI offers occasional goodwill refunds or account adjustments according to user reports. If you want to keep service at lower cost, email [email protected] and request a retention offer stating your current plan, recent billing and why you want a discount. Mention proof of cancellation attempts if you faced billing problems. The research shows some users received one-off refunds as a goodwill gesture.

What cancelling saves you - math and cheapest alternative

Compute annual cost from published prices:

  • Premium monthly: £14.99 x 12 = £179.88 per year.
  • Premium annual: £99.99 billed annually - equivalent monthly = £99.99 / 12 = £8.33 per month.
  • Yearly plan (reported monthly equivalent): £8.33 x 12 = £99.96 per year (reported figure for annual billing comparisons).

Savings examples:

  • Switching from Premium monthly to Premium annual: £179.88 - £99.99 = £79.89 saved per year.
  • Cancelling Premium monthly entirely saves £179.88 per year.

Cheapest real alternative noted by users for basic AI search or assistant tasks is Perplexity AI with a free tier at £0 per month; use it for basic research and QandA if you want to stop paid billing immediately.

What to do after cancelling Caktus AI

Confirm access and billing

Check your account dashboard for a "Cancelled" or "Subscription ended" status and keep any confirmation emails. For App Store or Play Store cancellations, keep the store confirmation screenshot or email. Monitor your bank statement for one billing cycle after cancellation to ensure no further charges.

Data and account deletion

If you want your account and data removed, request account deletion from [email protected] and specify the data to be removed. Keep written proof of the request. Caktus AI has a public legal page where privacy and data policies are published: https://caktus.ai/legal.

Re-activation

To re-activate, sign in and choose a plan or re-subscribe via App Store or Play Store. Re-activation may restore previous settings but do not assume prior billing history will be restored without confirmation from support.

Next steps and practical checklist

Follow this checklist to make your cancellation definitive and defensible.

  • Take a screenshot of your current subscription status in the dashboard or App Store/Play Store.
  • Save confirmation emails from Caktus AI or the App/Play Store.
  • If you used a trial, note the trial start and billed date and keep proof.
  • Email [email protected] asking for written confirmation of cancellation and keep the response.
  • If you send a registered letter, keep the receipt and delivery confirmation.
  • Check bank or card statements for 60 days after cancellation for any unexpected charges.
  • If charged after cancellation, prepare a timeline and evidence and contact your card issuer for chargeback or Section 75 if appropriate.
  • If you want your data deleted, request deletion by email and keep all replies.
