Find the purchase first
Keep your receipt and identify whether you bought from Avast, Google Play, the App Store or a reseller. The purchase channel determines where you manage billing. Sign in using the account associated with that receipt.
Check before making changes
Review the product, current term and number of covered devices. Check the billing date separately from the expiry date. Save a copy of any confirmation after changing a subscription.
Renewal controls
For an eligible website purchase, use the subscription-management area of your Avast Account and follow the cancellation prompts. Store purchases are managed through the relevant store. Uninstalling the app does not stop subscription billing.
Cancellation and refunds are different
Stopping renewal prevents a future renewal when completed in time; it is not itself a refund request. Consult the seller’s current refund policy for your purchase. Check the confirmation and the displayed end date rather than assuming the change is complete.
Moving to another device
Check the licence allowance and supported platforms before installing. Use an official installer for the new device and activate the matching app. Avoid sharing account access or an activation code with other people.
