Cancel by reason

Cooling-off (buying online) - right to cancel

If you bought iolo software online you have a 14 day cooling-off right under the Consumer Contracts Regulations 2013 when the purchase is a distance contract. If you requested download or immediate execution of digital content and gave express consent and acknowledged losing the right to cancel, the 14 day right may not apply. Notify iolo with a clear statement to cancel. See the renewal cooling-off provisions under the Consumer Rights Act 2024 at Consumer Rights Act 2024 - cooling-off.

Required proof documents: order number, purchase email, license key or proof of payment. Applicable law: Consumer Contracts Regulations 2013 and Consumer Rights Act 2024.

Dissatisfaction within 30 days - refund request rule from iolo

iolo requires refund requests to be received by telephone or email within thirty (30) days of the purchase date. You must provide proof of purchase date, price, sales receipt and/or license key. Refunds are issued to the original card less a 15% processing fee and less any discounts or rebates. See iolo's sales and refund policy at iolostore sales-policy and iolo knowledge base.

Required proof documents: proof of purchase, license key, transaction receipt. Applicable policy: iolo sales and refund policy.

Price increase or changed terms

If iolo increases the price at renewal or changes the service materially you may have rights under the Consumer Rights Act 2015 and the Consumer Rights Act 2024 subscription rules to cancel. For each renewal cooling-off period the trader must provide a notice of the renewal and any refund entitlement. If the renewal notice is not provided, you may be entitled to cancel for unfair change.

Required proof documents: renewal notice, invoice showing new price, prior subscription details. Applicable law: Consumer Rights Act 2015 and Consumer Rights Act 2024.

End of commitment

If your subscription has a finite term that ends, cancellation is effective at term end by not renewing. If you want to stop future billing, turn off automatic renewal in My Account before the next period.

Required proof documents: account subscription details or invoice. Applicable law: contract terms and Consumer Rights Act 2015 regarding unfair contract terms.

Moving or change of circumstances

iolo does not publish a specific policy for moving or change of circumstances. To request termination for such reasons contact [email protected] and provide supporting documents (for example, proof of sale of device). iolo's published refund exceptions and rules apply to refunds.

Required proof documents: Not published by iolo.

Death of subscriber

iolo does not publish specific rules for termination on death. If you need to close an account after the death of a subscriber contact [email protected] and provide a copy of the death certificate and proof of authority to act for the estate. iolo's public policy does not list this scenario explicitly.

Required proof documents: Not published by iolo.

Negotiate or save

Before cancelling: negotiate

iolo is known to offer retention discounts or special renewal prices in some cases. A published customer report described iolo emailing a half-price offer instead of providing a full refund. When you contact iolo ask for a retention offer, state the renewal charge you received, and request a price-match or discount. Use these steps: call support or email [email protected], reference your order and ask explicitly for a retention discount or cancellation with refund.

What cancelling saves you

Use iolo public annual prices to calculate yearly saving by cancelling. Example calculations using iolo published annual prices:

  • System Mechanic (special offer) annual = £27.06. Monthly equivalent = £27.06 / 12 = £2.26. Calculation: £2.26 x 12 = £27.06 per year.
  • System Mechanic typical annual = £29.95 (low) to £39.95 (high). Monthly equivalent low = £29.95 / 12 = £2.50. Calculation: £2.50 x 12 = £29.95 per year.
  • System Mechanic Pro annual = £44.30. Monthly equivalent = £44.30 / 12 = £3.69. Calculation: £3.69 x 12 = £44.28 rounded to £44.30 per year.
  • System Mechanic Ultimate Defense annual = £50.20. Monthly equivalent = £50.20 / 12 = £4.18. Calculation: £4.18 x 12 = £50.16 rounded to £50.20 per year.

Yearly saving examples when cancelling:

  • Cancel Ultimate Defense: save £50.20 per year.
  • Cancel Pro and switch to System Mechanic special offer: save £44.30 - £27.06 = £17.24 per year.

Cheapest real alternative (example): CCleaner Professional annual license at £19.95 per year. Switching from System Mechanic Pro (£44.30) to CCleaner Professional (£19.95) saves £44.30 - £19.95 = £24.35 per year.

What to do after cancelling iolo

Check final billing and refunds

After cancellation verify your bank or card statement for final charges and any refund. iolo issues refunds to the original card less a 15% processing fee if the refund request met the 30 day rule. Keep the refund confirmation and final invoice.

Data and account access

Keep a copy of your license key and any download installers if you want to reinstall later. If you lose account access, contact [email protected] and provide proof of purchase to recover account details.

Uninstall and device steps

If you no longer want the software uninstall System Mechanic via Windows Settings - Apps - Uninstall and remove any iolo browser extensions if installed. Cancelled subscriptions do not always uninstall software; you must remove it yourself if you choose.

Re-activation

You can re-subscribe later via the iolo purchase pages. Any refunds already given do not guarantee future promotional pricing.

Next steps and practical checklist

Follow this checklist to cancel and protect yourself.

  • Locate your order number and license key from your confirmation email or account.
  • Turn off automatic renewal in My Account or send a cancellation email to [email protected].
  • If seeking a refund, request it within 30 days and include proof of purchase and reason for dissatisfaction.
  • Keep copies of all communications and screenshots of confirmations.
  • If you are billed after cancellation, contact iolo and your card issuer for chargeback or Section 75 if eligible.
  • Uninstall the software from your PC if you no longer want it installed.
