Application End User License Agreement
Last Updated: May 8, 2026
Subject to your continued compliance with this EULA, Fizzify grants you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable license to download, install, and use the Kayro Mobile application on devices that you own or control, solely for your personal or internal business use. The application is licensed to you, not sold.
Kayro Mobile requires a connection to a Matrix-compatible homeserver to function. You are responsible for selecting and securing the homeserver, and for any agreement between you and the homeserver operator. Fizzify does not operate or warrant any third-party Matrix homeserver.
In addition to the acceptable-use rules in our general Terms of Service, you agree not to:
Kayro Mobile lets you exchange messages, media, and calls with other users. You retain ownership of all content you send. You are responsible for the content you share and for complying with applicable laws and the rules of the homeserver and rooms you use. We provide tools to block users and to report objectionable content; reports go to the homeserver operator and, where appropriate, to Fizzify Inc. We act on credible reports of abuse, including by removing offending users' access to Fizzify-operated services and by cooperating with law enforcement when required by law. Fizzify does not pre-screen end-to-end-encrypted message content and cannot decrypt it.
Voice and video calls use WebRTC and the Matrix call protocol. Quality and reliability depend on your homeserver, your network, and the other participants' devices. Fizzify does not record, store, or transcribe calls.
The Kayro Mobile application, including its code, design, graphics, logos, and the "Kayro" mark, is owned by Fizzify Inc. or its licensors. The application is built upon open-source projects, including portions licensed under Apache 2.0, MIT, and the Matrix Specification. Open-source attributions are available inside the application's About screen and on request.
Fizzify may release updates to the application at its discretion. Some updates may be required to continue using the application. Fizzify may also add, modify, or remove features over time.
If you obtained the application through the Apple App Store or Google Play Store, the terms of that store also apply, and the following supplemental terms control over conflicting provisions:
THE APPLICATION IS PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS, WITHOUT WARRANTIES OF ANY KIND. FIZZIFY DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND ANY WARRANTY ARISING OUT OF COURSE OF DEALING OR USAGE OF TRADE. WE DO NOT WARRANT UNINTERRUPTED OR ERROR-FREE OPERATION, OR THAT DEFECTS WILL BE CORRECTED.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, FIZZIFY'S TOTAL LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THE APPLICATION OR THIS EULA SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID FOR THE APPLICATION DURING THE TWELVE MONTHS PRECEDING THE CLAIM OR (B) ONE HUNDRED DOLLARS (USD $100). IN NO EVENT SHALL FIZZIFY BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES.
You agree to indemnify, defend, and hold harmless Fizzify and its officers, directors, employees, agents, and affiliates from and against any claim, damage, loss, liability, cost, or expense (including reasonable attorneys' fees) arising from your use of the application, your violation of this EULA, your User Content, or your violation of any applicable law or any rights of a third party.
The license granted in Section 1 terminates automatically if you breach this EULA. You may terminate the license at any time by uninstalling the application. Sections 4, 6, 9, 10, 11, and 13–15 survive termination.
This EULA is governed by the laws of the State of Wyoming, USA, without regard to its conflict of law provisions. Any dispute will be resolved exclusively in the state or federal courts located in Sheridan County, Wyoming, and you consent to personal jurisdiction and venue there.
We may update this EULA from time to time. Material changes will be surfaced inside the application on next launch and will update the "Last Updated" date at the top of this page.
