Withdrawal, Cancellations and Refunds
Version 1.3 — effective as of October 10, 2026
1. Withdrawal button
You may revoke any purchase within 10 calendar days from the date you made it, without giving reasons and at no cost (Consumer Protection Law, Ley 24.240, art. 34; Civil and Commercial Code (Código Civil y Comercial), art. 1110; Resolución SCI 424/2020; Disposición 954/2025).
How to do it:
- Go to the WITHDRAWAL BUTTON. It is at the top of every page of the Site and does not require registering or signing in.
- Provide your name, the email address used for the purchase and, if you have it, the order number (CK-…) or the license key. This helps us find it faster.
- You immediately receive an identification code for the request, which we also send you by email.
What happens next:
- If the license has not been activated on any device, we refund the full amount paid, through the same payment method, via Mercado Pago. The time it takes to be credited depends on the payment method and its issuer.
- The license is revoked. If it was a subscription, it is cancelled, so there will be no further charges.
- Exception (art. 1116 of the Código Civil y Comercial): if the license has already been activated on any device, withdrawal does not apply, because the software has been enabled for use. The date of the first activation is recorded, even if the device is released afterwards. We inform you of this before the purchase, and the 30-day free trial lets you try the App with no commitment.
- Bundles: the exception applies App by App. We refund the part of the price of the Apps that have not been activated, in proportion to the amount actually charged according to the list price of each one, and we revoke only those licenses. Apps already activated keep their license and the bundle price; if it was a subscription, subsequent debits are reduced to those Apps.
- Signature database subscription (CheshireKat Antivirus): the databases for each period are delivered as soon as the payment is credited, so there is no refund of what has already been paid. When you withdraw, the subscription is cancelled immediately, with no further charges, and the databases keep being updated until the end of the period paid. Your one-time payment license does not change.
To verify that the request comes from the person who made the purchase, we may ask you for confirmation from your account's email address (Disposición 3/2026).
2. Service cancellation button
You can cancel a monthly subscription or a signature database subscription at any time, without penalty and without giving reasons:
- from "My account", with one click, or
- with the SERVICE CANCELLATION BUTTON, which does not require signing in.
You immediately receive an identification code. When the email and the reference match an active subscription, the cancellation is made immediately in Mercado Pago. Otherwise, we process it within 24 hours.
After cancellation:
- no further charges are made;
- the license keeps working until the end of the period already paid. With the signature database subscription, the databases keep being updated until then and the one-time payment license does not change.
3. Free trial
The 30-day trial is free of charge and does not require a card: there is nothing to cancel or refund. When it ends, the App stops working until you purchase a license.
4. Other refunds
Outside the withdrawal period, we review each case: for example, duplicate charges or faults that prevent you from using the App and that we cannot resolve. Write to us at evazquez@amcisys.com.ar or use the contact form.
5. Chargebacks
If you dispute a payment with your bank or Mercado Pago (chargeback), the license for that purchase is revoked. If the chargeback is resolved in favor of the payment, we reactivate it.
Before starting a chargeback, we ask you to write to us: a withdrawal or a refund is usually faster.
6. Complaints
If you are not satisfied with the response, you may file a complaint with the enforcement authority: Consumer protection (Argentina). For complaints, click here.
