Section 01

Acceptance of terms

By using S3 Viewer (“the Service”), you agree to these terms. If you do not agree to them, please do not use the Service.

Section 02

The service

S3 Viewer is open-source software for viewing and managing objects in S3-compatible storage. The software is provided as-is and may be self-hosted. The hosted version, operated by May Inc., is provided as a convenience and may change or be discontinued. These terms cover that hosted version.

Section 03

Self-hosting

A self-hosted instance is run by whoever operates it. These terms do not apply to it: the operator sets its own terms, and May Inc. is not a party to your use of that instance and does not provide, support or stand behind it. Your use of the software itself is governed by the MIT license alone.

Section 04

Accounts

You are responsible for your account, for keeping secure any credentials you choose to connect, and for everything done through your account. Your use of any storage you connect remains subject to your agreement with that storage provider.

Section 05

Fees

The service is currently offered free of charge; we may introduce paid plans with notice.

Section 06

Acceptable use

Use the Service only for lawful purposes. Do not use it to infringe anyone's rights, to store or distribute unlawful content, to access storage you are not authorized to access, or to interfere with or overload the Service.

Section 07

Intellectual property

The software is made available under the MIT license, and you may use it on those terms. The S3 Viewer name and logo are trademarks of May Inc. and are not covered by that license. Please don't present a fork or your own instance as run by or affiliated with May Inc.

Section 08

Disclaimer of warranties

The Service is provided “as is” and without warranties of any kind, express or implied. We do not warrant that the Service will be uninterrupted, error-free, or suitable for a particular purpose. Actions taken through the Service, such as deleting or renaming, may not be reversible.

Section 09

Limitation of liability

To the maximum extent permitted by law, May Inc. is not liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of data, revenue or profits, arising from your use of the Service.

Section 10

Termination

You may stop using the Service and delete your account at any time. We may suspend or end access to the hosted version if these terms are breached or where necessary to protect the Service. Your rights to use the open-source software under its license are unaffected.

Section 11

Changes to these terms

We may update these terms from time to time. If we do, we will post the updated version on this page and revise the date above. Continuing to use the Service after that means you accept the updated terms.

Section 12

Governing law

These terms are governed by the laws of the jurisdiction in which May Inc. is established, without regard to conflict-of-law rules. Nothing here removes any mandatory consumer protections available to you where you live.

Section 13
