Effective August 2, 2026
These terms cover using Zas. Using it means accepting them. They are written to be read, not to be survived. Questions: support@zas.red
Zas moves text and files between your devices and the people you choose, encrypted end to end, and then gets out of the way. It is a corridor, not a warehouse: what you send has an expiry, and only a pinned item stays until you release it. Zas is provided as a service, not sold to you, and these terms transfer no ownership of it.
You can use Zas with a Google or Apple account, or with an anonymous session that asks for nothing. Either way, what happens inside it is yours: look after the way you sign in, and look after the link to an anonymous session. Whoever holds that link holds that session. You must be old enough to agree to these terms where you live, and Zas is not directed at children under 13.
Because content is encrypted before it leaves your device, we cannot see what you send and we do not monitor it. That is a design decision, and it does not make the list above optional. When we act, we act on reports and on what the server does see — an account, a session, a channel — never on content we cannot read.
You keep every right you hold in what you send. You give Zas only what running it requires: to store the encrypted bytes, move them between the devices and people you chose, and delete them when they expire. Nothing broader, and nothing that would need us to read them — which we cannot do.
The encryption is the point, and it carries a cost worth saying plainly. A public link carries its key in the link itself, and an anonymous session lives behind the link holding its code. If you lose that link, what sits behind it is gone — for you and for us alike. There is no reset, no back door, and no support request that undoes it. This is not a limitation we intend to remove.
Zas is free today, within the limits the app shows you: how much you can store, how many channels you can keep, and how long things last. The app mentions a Pro plan with higher limits. It cannot be bought yet, and nothing here charges you anything. If paid plans open, their prices and billing terms will be published before they apply to anyone.
Zas is offered as it is. We work to keep it running, but we do not promise it will be available without interruption, and we do not promise any particular speed or capacity. Limits and expiry periods can change as the service changes. Treat Zas as a way to move things, not as the only place they exist: keep your own copy of anything you cannot lose.
You can leave whenever you want. Delete an item, a channel, or everything at once from Settings → “Delete my account”. An anonymous session also expires on its own. We can suspend or close an account that breaks the section above, or one the law obliges us to act on. Where warning you first is reasonable, we will.
Zas is offered without warranties of any kind, as far as the law allows. We are not answerable for content you or anyone else sends, for what is lost because a link or a key was lost, or for indirect damages. Nothing here removes rights you hold as a consumer that cannot be removed by agreement.
These terms are governed by the laws of the Argentine Republic. Any dispute goes to the ordinary courts of the City of Buenos Aires, without prejudice to the court that is available to you as a consumer where you live.
If these terms change, this page and its effective date are updated. Continuing to use Zas after that means accepting the new version.
