Terms of Service
In force from 8 August 2026.
1. Definitions
"Service" means the Katabasis application made available at katabasis.quest. "Operator" means the private individual who develops and administers the Service. "User" means any natural person who has been granted access to the Service by invitation. "Content" means any data, text or file submitted to the Service by a User.
2. Nature of the Service
2.1. The Service is a private, non-commercial application operated by a private individual. It is not a commercial product, it is not offered to the public, and it is not marketed, sold or licensed.
2.2. No consideration of any kind is charged or accepted for access to the Service. The Service contains no advertising, and Content is not used for advertising, profiling, training of automated systems or any other commercial purpose.
3. Access
3.1. Access is by personal invitation only. There is no public registration. An invitation is personal to its recipient and may not be transferred.
3.2. Authentication is performed by means of a passkey held on the User's own device and, at the User's option, an additional time-based code. The User is responsible for maintaining control of the devices and recovery code by which access is obtained.
3.3. The Service is not intended for persons under the age of 18, and access is not knowingly granted to them.
4. Acceptable use
4.1. The User shall not use the Service for any unlawful purpose, nor to store or transmit material that is unlawful in the User's jurisdiction or in Brazil.
4.2. The User shall not submit personal data relating to third parties without a lawful basis for doing so. Where such data is submitted, the User is responsible for that submission.
4.3. The User shall not attempt to access any account other than the User's own, nor to circumvent, disable or test the security measures of the Service. Any vulnerability discovered inadvertently should be reported to the Operator by the means described in clause 10, and a report made in good faith will not be treated as a breach of this clause.
5. Content and ownership
5.1. The User retains all rights in Content submitted by the User. No licence, assignment or transfer of rights in Content is granted to the Operator beyond the limited technical permission to store, reproduce and display that Content for the sole purpose of operating the Service for that User.
5.2. The Service provides a function by which a User may export a complete copy of the User's own Content at any time, without request and without charge.
6. Availability
6.1. The Service is provided without any undertaking as to availability, continuity or performance. It operates on a single server and may be unavailable, whether planned or not, at any time and without notice.
6.2. Backups are taken, but no undertaking is given that any particular Content will be recoverable following hardware failure, software error or operator error. The User is advised to retain an independent copy of any Content the loss of which would be material.
6.3. No undertaking is given that the Service will continue to be operated for any period.
7. Termination
7.1. The User may terminate the User's account at any time from within the Service. Termination takes effect immediately and results in the deletion described in the Privacy Policy. No retention period applies and the account cannot be restored afterwards.
7.2. The Operator may suspend or terminate access, with or without cause, and may discontinue the Service in its entirety. Where the Service is to be discontinued in its entirety, the Operator will give prior notice by the means by which the User was invited, so far as that is reasonably possible.
8. Disclaimer and liability
8.1. To the fullest extent permitted by applicable law, the Service is provided "as is" and "as available", without warranty of any kind, whether express or implied, including any implied warranty of merchantability, fitness for a particular purpose or non-infringement.
8.2. To the fullest extent permitted by applicable law, the Operator shall not be liable for any indirect, incidental, special or consequential loss, nor for any loss of data, profit or opportunity, arising out of or in connection with the use of or inability to use the Service.
8.3. Nothing in these Terms excludes or limits liability for fraud, for wilful misconduct, or for any other liability that cannot lawfully be excluded or limited. Where the User is a consumer, rights conferred by mandatory consumer protection law are unaffected.
9. Amendments
9.1. These Terms may be amended. The amended Terms take effect on publication at this address, and the date shown above is updated accordingly. Continued use of the Service after publication constitutes acceptance of the amended Terms.
9.2. No individual notice is given, as the Service holds no contact address for its Users.
10. Governing law and contact
10.1. These Terms are governed by the laws of the Federative Republic of Brazil. The courts of the Operator's domicile shall have jurisdiction, without prejudice to any competent forum that mandatory law confers on a User who is a consumer.
10.2. The Operator may be contacted through the feedback function available on every page of the Service or, where access is not possible, by replying through the channel by which the invitation to the Service was received.
