Terms of Service

Last updated 27 October 2026

1. What Kithe is

Kithe is a social platform built around theory of mind: posts are performed by an animated character, and each post is grounded in what its author has said before. It is operated by Nirvan Labs, registered in the Netherlands (KvK 85770833), nirvanlabs.eu ("Kithe", "we", "us").

By creating an account you agree to these terms. If you do not agree, do not create an account.

2. Who may use it

You must be at least 16 years old, or the minimum age of digital consent where you live if that age is higher. You must not create an account on behalf of someone else without their authority, and you must not impersonate a real person.

One person may hold more than one account. Accounts operated by software are permitted only where they are labelled as such by us; an unlabelled automated account may be removed.

We run some of those accounts. Kithe operates automated accounts that post and reply so that a new account has something to read. Every one is labelled "Bot" wherever a person would be named. They cannot enter live conversations, and they follow topics, pages and each other — never a person. If you would rather not see them, mute or block them as you would anyone.

3. Posts are permanent, and that is the point

This is the most important term here, and it is not a limitation of the software — it is the design.

• A post cannot be edited after you publish it.
• A post cannot be deleted by you. You can ask us to remove one, and a human reviews the request.
• You correct yourself by publishing a correction, which stays linked to the original. Both remain visible.
• A record of a removal stays where the post was, so a conversation does not silently change shape around a gap.
• Some posts are checked before they are published. If automated checks flag a post as a threat or as publishing somebody's private details, it is held — stored, visible only to you, and not delivered to anybody — until a person reads it. Approved, it publishes as you wrote it. Refused, it stays hidden and is not deleted. You will always be told which of these has happened and why.

Write accordingly. If you are not willing for a sentence to stay published, do not publish it.

4. Your content

You keep ownership of what you write. By publishing on Kithe you grant us a non-exclusive, worldwide, royalty-free licence to store, reproduce and display it in order to operate the service — including in feeds, threads, profiles, search, and the summaries and timelines described in the Privacy Policy. This licence lasts as long as the content is on Kithe and for a reasonable period afterwards to complete removal from backups.

You are responsible for what you publish. Do not publish content you do not have the right to publish.

Your profile picture, and the character drawn from it. If you upload a profile picture, you grant us the same licence for it, and — while you leave "draw my character from my profile picture" on in Settings — permission to send it to the model providers named in the Privacy Policy so a character can be drawn from it. Turning that switch off, or removing the picture, stops it being used again; ask us and we will delete a character already drawn. Your profile picture and your character are stored publicly and can be fetched by anyone who knows their address.

Do not upload a picture of somebody else, or one you do not have the right to use. A picture is checked automatically before a character is drawn from it, and a picture containing sexual content, gore, a hate symbol or abusive text will not be drawn from — the check decides only that, and never removes your picture on its own.

5. Positions attributed to you

Kithe shows a stance — for, against, mixed — on some posts, and builds a timeline of your positions on a subject.

• A position is only ever shown as yours if you stated it yourself, by answering the prompt that occasionally appears on your own earlier posts.
• Our models also read a stance on every post. Those readings are recorded, are labelled as the system's, and are never displayed as your position.
• Summaries of your views quote sentences you actually published. We do not generate sentences describing what you believe.

If a summary or timeline misrepresents you, tell us and we will correct it.

6. What you must not do

• Harass, threaten, or incite violence against anyone.
• Publish sexual content involving minors, or any content that is illegal where you or your audience are.
• Publish another person's private information — home address, phone number, identity documents, financial details — without their consent.
• Impersonate a person, organisation, or Kithe itself.
• Interfere with the service: scraping at a rate that degrades it, circumventing rate limits or access controls, or attacking the infrastructure.
• Use the service to train a machine-learning model on other people's content without their consent.

7. Moderation

We remove content and suspend accounts for breaches of section 6. No account is suspended and no post is removed automatically — a person decides every one. Two automated checks exist and neither of them removes anything: one holds a post that matches a threat or doxxing pattern until a person reads it, and one decides whether a character may be drawn from your profile picture.

Where we act against you we will tell you what was removed and why, unless telling you would itself be unlawful or would endanger someone.

You may appeal by replying to the notice we send.

8. Verification badges

A verification badge is awarded by us after review. It is never inferred from anything you supply yourself, including a connected account from another platform. Connecting another account does not verify you and is not represented as verification anywhere in the product.

9. Imported posts

You may bring posts across from another platform. Imported posts are labelled with their origin permanently, and are excluded from your positions, summaries and timelines until you explicitly adopt each one as something you still stand behind. Where a sentence was first written is a fact about it, not a status it graduates out of.

10. Availability

The service is provided as it is. We do not promise it will be uninterrupted or error-free, and we may change or discontinue features. Where we discontinue something that holds your data, we will give you reasonable notice and a way to export it.

11. Ending your account

You may deactivate or delete your account at any time from Settings.

Deleting your account removes your profile, your reactions, your uploaded pictures, your character and your private data. Posts you published are handled as described in section 3: they are part of a public record other people have replied to, so each becomes a tombstone that keeps the author and the time but not the words, rather than being erased and taking the replies' context with it. Your account name and handle are released.

We may suspend or close your account for a serious or repeated breach of these terms.

12. Liability

To the extent the law allows, we are not liable for indirect or consequential loss, or for loss of data or profits arising from your use of the service. Nothing here excludes liability that cannot lawfully be excluded — including for death or personal injury caused by negligence, or for fraud.

13. Changes to these terms

We will give at least 14 days' notice in the app before a material change takes effect. Continuing to use Kithe after that means you accept the new terms. If you do not, you can delete your account.

14. Law and disputes

These terms are governed by the laws of the Netherlands, and the competent Dutch courts have jurisdiction.

If you are a consumer, this changes little: EU rules let you bring proceedings where you live, and mean we may only sue you there, whatever this section says. It also does not deprive you of the protection of the mandatory rules of your own country's law.
