Kryfo is free and open source, and there is no account to make. Use it within the law, keep public listings legal, and keep a backup, because it comes without a warranty. Tips on Google Play support the work, and everything in Kryfo stays free for everyone.
Who offers Kryfo
Kryfo is made by Marios, an independent developer, not a company. His full details are in the legal notice.
What Kryfo is
Kryfo is free, open-source software. Its code is published under the GNU General Public License, version 3, which says what you may do with the code and has its own disclaimer of warranty.
These terms take away nothing the license gives you. They cover what it does not: our servers, public listings and tips.
No account
You never sign up. Kryfo does not ask for your phone number, your email address or your name, and your identity and messages live on your phone.
Our servers keep no accounts, no connection logs, no IP addresses, no contact lists and no member lists. They carry encrypted messages that nobody can read, for up to 14 days so a phone that was offline can catch up, and the public handles people choose to claim. The privacy notice says what each server sees.
Fair use
Use Kryfo within the law where you are. Do not use our servers to attack, flood or overload them, or anyone else.
Public listings, such as handles and their short descriptions, can be seen by anyone, so they must not contain anything illegal. They are the only thing we moderate. A listing that breaks the law or these terms is removed, and reports go to the address in the legal notice.
Your chats are encrypted on your phone. We cannot read them, so we do not moderate them, and you are responsible for what you send.
Tips on Google Play
The Google Play version of Kryfo lets you leave a tip to support the work. A tip is a payment you choose to make. It gives you a supporter badge and nothing else: everything in Kryfo is free for everyone, with or without one.
Tips are paid through Google Play, under Google Play's terms. Google handles the payment, and we never see your card details. Refunds follow Google Play's refund policy, so ask Google Play for one.
No warranty
Kryfo is made with care and provided as it is, without a warranty of any kind. It has not been independently audited yet. It can have bugs, a message can arrive late or not at all, and our servers or the public relays it uses can be slow or unreachable. There is no promise that a server keeps running.
Your identity and messages live only on your phone. Keep a backup and its passphrase, because without them nobody can bring your data back.
As far as the law allows, we are not liable for damage that comes from using Kryfo or from not being able to use it. This does not limit any liability that the law does not allow to be limited.
Changes
If these terms change, the date at the top changes with them, and the previous versions stay in the git history of this site.
