Terms of Service

Version v1 · Effective 2026-05-23

1. Acceptance

These Terms of Service (the “Terms”) are a binding agreement between you (“you”) and Seiraiyu LLC, a Georgia, USA limited liability company (“Seiraiyu”, “we”, “us”). By creating an account or using the Kisenon service (the “Service”) you agree to these Terms. If you do not agree, do not use the Service.

2. Alpha status

The Service is alpha software. We make no service-level guarantees, no uptime commitments, and no data-durability commitments beyond best effort. We may modify, suspend, or discontinue the Service, in whole or in part, at any time and without notice. Your data may be lost. Do not use the Service as the sole copy of production data.

3. Account requirements

You must be at least 18 years old to use the Service. You must provide accurate registration information. You authenticate via a third-party identity provider (currently Google or GitHub); you are responsible for the security of that identity. You may not share your account or permit anyone else to use it.

4. Acceptable use

You agree not to:

Use the Service to store or transmit content that is unlawful, infringing, defamatory, or that you do not have the right to store or transmit.
Use the Service to attack, probe, or interfere with the Service itself, with other users, or with any third party (denial-of-service, scanning, credential stuffing, malware distribution, etc.).
Resell, sublicense, or rent the Service.
Circumvent quotas, rate limits, or access controls.
Scrape or automate beyond what the documented public API permits.

We may suspend or terminate your account immediately for abuse.

5. Service description

The Service is a hosted Postgres-compatible database with branching, scale-to-zero, and connection pooling. The storage layer is derived from open-source software released by Neon Inc. under the Apache 2.0 license, with modifications by Seiraiyu LLC. See Open-Source Attributions for the full component list.

6. Your content

You retain all rights to the data and content you place into the Service (“Your Content”). You grant Seiraiyu a worldwide, royalty-free license to host, store, transmit, replicate, back up, and display Your Content solely as necessary to provide the Service to you. We do not mine Your Content for advertising, profiling, or model training.

7. Fees

During the alpha phase the Service is provided at no charge. We will introduce pricing at general availability with prior notice. Continued use after pricing takes effect constitutes acceptance.

8. Termination

You may terminate your account at any time by deleting it from the settings page or by emailing legal@seiraiyu.com. We may terminate or suspend your account immediately for breach of these Terms, for abuse, or in response to legal process. On termination we will delete Your Content after a 30-day grace period unless legally required to retain it.

9. No warranty

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND ACCURACY. SEIRAIYU DOES NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE.

10. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, SEIRAIYU’S TOTAL LIABILITY UNDER THESE TERMS IS LIMITED TO THE GREATER OF (a) THE FEES YOU PAID TO SEIRAIYU IN THE TWELVE MONTHS BEFORE THE EVENT GIVING RISE TO LIABILITY (DURING ALPHA, ZERO) OR (b) ONE HUNDRED US DOLLARS ($100). SEIRAIYU IS NOT LIABLE FOR INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, LOST REVENUE, OR LOST DATA, EVEN IF ADVISED OF THE POSSIBILITY.

11. Indemnification

You agree to defend, indemnify, and hold harmless Seiraiyu from claims arising out of (a) Your Content, (b) your breach of these Terms, and (c) your use of the Service in violation of law. We agree to defend, indemnify, and hold you harmless from third-party claims that the Service, as provided by us and used in accordance with these Terms, infringes that third party’s US intellectual property rights.

12. Governing law and venue

These Terms are governed by the laws of the State of Georgia, USA, without regard to conflict-of-laws principles. Any dispute that cannot be resolved informally will be brought exclusively in the state or federal courts located in Fulton County, Georgia, and you consent to personal jurisdiction there.

13. Changes to these Terms

We may update these Terms from time to time. For material changes we will notify you by email or in-app at least 14 days before the change takes effect. Continued use of the Service after the effective date constitutes acceptance of the updated Terms. The current version is identified at the top of this page.
