Terms of Service

The agreement

These terms cover tiero.io, the tiero API, the embeddable builder and the tiero MCP server (together, "tiero"). By creating an account or using tiero you agree to these terms, the Privacy Policy, the Content Policy and the DMCA and Copyright Policy. If you do not agree, please do not use tiero.

You must be at least 13 years old to create an account.

Your account

• You can sign up with an email address and password, or with Discord, Twitch or Google. Keep your login details safe; you are responsible for what happens under your account.
• Usernames are public. When you change yours, the old one stays reserved and its links redirect to your new one.
• A template or list you make public shows as unlisted until your email is verified and your account is a day old. It then goes public automatically.
• You can delete your account at any time from your account settings.

Your content

"Your content" means the templates (catalogs), items, images, tier lists, names and descriptions you create or upload.

You keep ownership

You own your content. tiero does not claim ownership of anything you make or upload.

The licence you give us

So that tiero can work, you give us a worldwide, non-exclusive, royalty-free licence to host, store, copy, display, resize and export your content, and to convert it to other formats, for the purpose of running and improving tiero. This includes showing it on tiero.io, in embeds on other sites, through the API and in exported images. The licence ends when you delete the content, except for copies that others have already exported or copied as the service allows (for example, a list someone copied from a public template) and backups that expire on their normal schedule.

You have the rights to what you upload

By uploading, you confirm that you own the content or have permission to use it this way, and that it does not infringe anyone's copyright, trademark, privacy or other rights. If you are not sure, do not upload it.

Uploaded images are viewable by anyone with the link

Images you upload are served from img.tiero.io and can be viewed by anyone who has the image link, even when the template or list that uses them is private or unlisted. Privacy settings control where a template or list is shown, not who can open an image link. Do not upload images you need to keep secret.

Acceptable use

You agree not to:

• post anything the Content Policy forbids;
• infringe someone else's copyright or other rights;
• get around rate limits, upload quotas, CAPTCHA checks or access controls, or use several accounts to do so;
• scrape tiero in a way that degrades the service, instead of using the API;
• probe, attack or disrupt tiero, its infrastructure or other users;
• pretend to be another person, creator or organization.

Premium

Premium adds the embeddable builder and higher upload limits. During launch it is granted by invitation and has no charge. A grant may have an end date; when it ends, your account returns to the free limits and embeds stop loading. Paid plans, if we offer them later, will come with their own terms.

API, embeds and agents

• API keys belong to your account. Keep them secret; anything done with your key counts as done by you. Revoke a key from your account settings if it leaks.
• Embeds work only on domains you have verified. You are responsible for the pages you embed the builder on.
• AI agents and apps you connect act on your behalf with the access you grant them. You can revoke that access at any time.
• We may change or limit the API to keep tiero reliable, and will try to give notice of breaking changes.

Suspension and termination

We may hide or remove content, or suspend or close an account, when it breaks these terms or the Content Policy, when the law requires it, or to protect users or tiero. Accounts that collect repeated copyright strikes are suspended, as the DMCA and Copyright Policy describes. Where we can, we tell you what happened and why.

Disclaimers and liability

tiero is provided "as is" and "as available". To the extent the law allows, we make no promises about availability, accuracy or fitness for a particular purpose, and we are not liable for indirect or consequential losses, lost data or lost profits. Keep your own copies of anything important; exports exist for that reason. Nothing in these terms limits rights you have under consumer law that cannot be waived.

Changes and contact

We may update these terms. When a change is significant we will say so on the site or by email before it takes effect. Using tiero after a change means you accept the new terms.
