On the main desktop distributions:

• Debian, Ubuntu and Mint: .deb package and APT repository.
• Fedora, RHEL and Alma: .rpm package and RPM repository.
• openSUSE: .rpm and zypper.
• Any other distro: AppImage.

Each app's requirements are listed on its product page.

Yes, when the published version includes packages for aarch64 (64-bit ARM). The downloads page shows the architectures available for each version.

The repository: you add it once and updates arrive through your usual package manager.

The AppImage is handy for a quick try or for distros without an official repository. The commands for each distro are on the downloads page.

For now, the site only sells the Linux versions.

You create an account, verify your email and activate the app's trial from "My account".

It lasts 30 days, on one device, with all features.

No. The trial doesn't ask for any payment method and nothing is ever charged automatically when it ends.

The app stops working with all its features until you buy a license. Your files are still yours.

Each app can be tried only once per account.

• One-time payment: you pay once and the license doesn't expire. It includes the version current when you buy, previous ones and updates released during 12 months. After that period you keep using the latest covered version forever.
• Monthly subscription: charged every month by automatic debit and includes all updates. You can cancel it whenever you want.

The details are in the Terms and Conditions.

With the antivirus trial or subscription, the signature databases are always updated.

With the one-time payment, the databases are updated with the signature database subscription, which is cheaper and is purchased from "My account" for that license. If you don't have it or you cancel it, the antivirus keeps protecting with the latest database installed.

Prices are in US dollars (USD) and are paid with Mercado Pago, in Argentine pesos, at the day's MEP dollar rate. Before paying you see the exact amount in pesos and the date of the exchange rate; the cents from the conversion always stay in your favor.

Published prices are final, with taxes included. We never see or store your card details.

With subscriptions, the price in dollars stays fixed and the amount in pesos is recalculated the day before each debit using that day's MEP dollar rate. That's why it may vary slightly from one month to the next.

If the price in dollars ever changes, we'll notify you by email at least 30 days in advance.

Yes. Buying two or more apps together, with the same license type and number of devices, you get 10 % off with two, 15 % with three and 20 % with the full Suite. Each app gets its own license.

Build your bundle on the pricing page.

As soon as Mercado Pago confirms the payment, the key appears in "My account". If the payment method is pending crediting, it appears once it's credited.

Request a business quote through the contact form.

On as many as you bought: 1, 3, 5 or 10. In "My account" you can see which devices are activated.

No. In "My account", release the old device and activate the app on the new one. Releasing devices is free and unlimited.

Yes. The app needs to connect to activate and then validates the license periodically, but it can work up to 7 days offline.

Only what's needed to manage the license:

• a technical identifier of the device, of which we store only a SHA-256 fingerprint;
• the device name;
• the app version;
• the architecture.

The details are in the Privacy Policy.

If you installed from the repository, they arrive with your normal system updates: apt upgrade, dnf upgrade, Discover or Software Updater.

If you use the AppImage, the latest version is always on the downloads page.

Your license covers the versions released up to 12 months after the purchase. The repository keeps the published versions, so you can go back to the latest covered one and pin it so the system doesn't change it:

• on Debian, Ubuntu or Mint: sudo apt install <package>=<version> and then sudo apt-mark hold <package>;
• on Fedora: sudo dnf install <package>-<version> and then sudo dnf versionlock add <package>.

If you'd rather get all updates, you can switch to the monthly subscription.

Compare the file's SHA-256 with the one listed on the downloads page.

The repository indexes are signed with GPG: apt and dnf check the signature automatically, and the key fingerprint is published on that same page.

Yes, within 10 calendar days from the purchase, without giving reasons, as long as you haven't activated the license on any device. If you've already activated it, withdrawal does not apply (art. 1116 of the Código Civil y Comercial). That's why, before buying, you can use the 30-day free trial.

Use the WITHDRAWAL BUTTON: no need to sign in. We refund the full amount paid through the same payment method.

In a bundle, we refund the share of the price of the apps you didn't activate, and the others keep their license. With the signature database subscription there is no refund, because the databases for the period have already been delivered: it is cancelled immediately and they keep being updated until the end of the period paid.

From "My account", with one click, or with the SERVICE CANCELLATION BUTTON, without signing in.

No further charges are made, and the license keeps working until the end of the period you already paid for. The same applies to the antivirus signature database subscription: the databases keep being updated until the end of the period paid.

It's the identification code for your withdrawal or cancellation request. We show it to you right away and send it to you by email. Keep it for any questions about that request.

No. We only use the essential technical cookies: session, form protection and language. We don't load resources from other companies either.
