Terms of Service

Effective 1 November 2026

These terms are an agreement between you and Celestin ("Celestin", "we", "us"), an independent AI service run from Indonesia. They cover the Celestin website and app, its credits server, the Celestin Connector and anything else we offer (together, the "Service"). By creating an account or using the Service, you agree to these Terms and the Usage Policy below, and you acknowledge our Privacy Policy. If you don't agree, please don't use the Service.

1. Who can use Celestin

• You must be at least 13. If you're under 18, a parent or guardian must agree to these Terms for you and is responsible for your use, including any purchase.
• Your account is for you. Keep your sign-in safe; you're responsible for what happens on your account. Tell us if you think someone else is using it.
• If you use Celestin for an organization, you confirm you're allowed to accept these Terms for it.

2. Your content

• What you give the Service (messages, files, pictures, code) is your Input. What the Service gives back (answers, code, apps, documents, pictures, videos) is Output. Together they're your Content.
• You keep the rights you have in your Input. As between you and us, and as far as the law allows, you own your Output, and we give you any rights we have in it.
• You're responsible for your Input: you need the right to use it, and it must follow the law and these Terms.
• Outputs aren't unique to you. Other people may get the same or similar outputs.
• We don't train AI models on your Content. We use it only to provide, secure and support the Service, as the Privacy Policy explains. The AI providers that answer your requests process your Input under their own terms for business customers.
• Help improve Celestin is on by default. We tell you about it the first time you sign in, with a button to turn it off, and you can turn it off in Settings anytime. While it's on, Celestin learns which AI models give the best answers from your 👍 and 👎, when you ask for another answer, and whether code runs: only which model answered, a few generic topic words and the outcome, never what you wrote.

3. AI can be wrong

• Outputs can be inaccurate, incomplete, out of date or inappropriate, even when they sound sure. Check them before you rely on them, especially for health, legal, financial, safety or other important decisions. Outputs aren't professional advice and don't represent our views.
• You're responsible for how you use Outputs, including anything you publish, sell or run. Make sure what you publish doesn't infringe anyone's rights, for example the names, logos, characters or likenesses of real brands, games, sports leagues, clubs or people.

4. Code, apps and your computer

Celestin can write and run code and build apps. If you connect your computer or other apps, it can run commands and change files there. It asks before changing anything on your computer unless you turn that off. Review what you allow, keep backups, and run code from Celestin at your own risk.

5. Other companies' services

• Celestin sends each request to AI models made by other companies (for example Anthropic, OpenAI, Google, xAI and others) through an AI gateway, and uses other services for web search, sign-in, hosting and payments. Their names and their models' names are their trademarks. Celestin isn't affiliated with or endorsed by them.
• Apps you connect yourself, such as Higgsfield, run on your own account with them, under their terms and prices; what they charge you is between you and them. When one needs a picture you attached, Celestin shares it through a private link that expires after 24 hours.
• We don't promise that any particular model or outside service stays available.

6. Plans, credits and payments

• Credits measure how much of the Service you use. A request uses credits according to the models and work it takes.
• Free accounts get credits that come back over time, within limits. Paid plans last 30 days, give credits within limits (in any 5 hours, in a week and in a month), and don't renew by themselves. Credit packs add credits that are used once a plan's limits are reached, and don't expire while your account and the Service exist.
• Credits have no cash value and can't be sold, transferred or exchanged for money.
• Prices are shown before you pay and may change. A change never affects a plan you've already paid for.
• QRIS payments are confirmed by hand. Card payments are processed by our payment partner, which may act as the seller of record under its own terms. We never see your full card number.
• Refunds. Changed your mind? Within 7 days of paying, if you've used less than a fifth of what you bought (a plan's month of credits, or a pack's credits), press Refund next to the payment in Account and you get that whole payment back: QRIS payments to the account you paid from, usually within 2 working days; card payments through our payment partner. What you bought ends when you ask. Outside that, a payment is final, except where the law gives you a right to a refund, or if something you paid for didn't work as described: then contact us and we'll put it right or refund you.
• If we stop offering the Service, we'll tell you in advance where we can and refund the unused part of any paid plan.

7. Fair use

• Don't get around the Service's limits, share or resell your account, use your account to power another product or service, or send automated traffic except through features we offer.
• We may limit, pause or refuse requests to protect the Service, other people, or the money that pays for it.

8. Ending your use

• You can stop using Celestin and delete your account at any time (Account → Delete account).
• We may suspend or close your account if you seriously or repeatedly break these Terms or the Usage Policy, if the law requires it, or to prevent harm. Where reasonable, we'll tell you why and give you a chance to respond. Credits on an account closed for a serious breach are lost, except where the law says otherwise.

9. Our rights

• The Service, its code, design, name and logo are ours (all rights reserved), apart from your Content and open-source parts under their own licences. Don't use the Celestin name or logo in a way that suggests we endorse you.
• If you send us feedback or ideas, we may use them without owing you anything.

10. No warranties

As far as the law allows, the Service is provided "as is" and "as available", without warranties of any kind, including that it will be uninterrupted or error-free, or that Outputs will be accurate or fit for a particular purpose.

11. Limits on our liability

• As far as the law allows, we aren't liable for indirect, incidental, special or consequential losses, or for lost profits, data or goodwill, and our total liability for all claims about the Service is limited to the greater of what you paid us in the 6 months before the claim and Rp100,000.
• Nothing in these Terms limits liability that can't be limited by law, such as for fraud or wilful misconduct, or your rights as a consumer under Indonesian law, including Law No. 8 of 1999 on Consumer Protection.

12. Your responsibility to us

As far as the law allows, you'll compensate us for claims, losses and costs caused by your Content, your use of Outputs, or your breaking these Terms or the law.

13. Changes to these Terms

We may update these Terms. If a change is significant, we'll tell you in the app at least 7 days before it takes effect, unless it's needed sooner for legal or security reasons. If you keep using the Service after a change takes effect, the new Terms apply. If you don't agree, stop using the Service and delete your account.

14. Law and disputes

These Terms are governed by the laws of the Republic of Indonesia. If there's a problem, contact us first and we'll try to solve it within 30 days. If we can't, either of us may take it to the competent courts or consumer dispute bodies in Indonesia, and you keep any rights the law where you live gives you.

15. General

• These Terms, the Usage Policy and the Privacy Policy are the whole agreement between us about the Service. If part of them can't be enforced, the rest still applies. Not enforcing a part now doesn't mean we give it up.
• You can't transfer your rights under these Terms without our consent. We may transfer ours as part of passing on the Service.
• These Terms are in English and Indonesian. Both are binding; if they differ, the Indonesian version prevails.

Usage Policy

These rules apply to everything you do with Celestin: what you ask it to do or make, and what you do with the results. Don't use Celestin to:

1. Harm children. No sexual content involving minors, no grooming, nothing that sexualizes children. We report it to the authorities.
2. Make weapons or plan violence. No help creating biological, chemical, nuclear or radiological weapons, explosives or illegal weapons, and no planning, threatening or glorifying violence or terrorism.
3. Attack computers or networks. No malware, ransomware, phishing kits, credential theft or denial-of-service, and no breaking into systems you don't own or haven't got written permission to test.
4. Deceive or defraud. No scams, phishing, fake reviews, impersonating people or organizations, forged documents, or disinformation, including to sway elections.
5. Harass, threaten or exploit people. No harassment, bullying, hate against protected groups, doxxing or stalking, and no sexual or intimate images of a real person without their consent, including deepfakes.
6. Invade privacy. No tracking or identifying people without their consent, collecting sensitive personal data unlawfully, or facial recognition of private individuals.
7. Encourage self-harm. Nothing that promotes suicide, self-harm or eating disorders. If you're struggling, please reach out to local emergency services or someone you trust.
8. Infringe intellectual property. No copying or distributing other people's copyrighted work, trademarks, characters or likenesses without permission: for example, a copy of an existing game, or a product that uses a real brand, league, club or player without a licence.
9. Decide about people without a human. No fully automated decisions about someone's credit, job, housing, insurance, education, legal or medical situation.
10. Break the law or our limits. Nothing illegal where you or the people affected are; no getting around credits, limits, safety measures or account rules; no reselling access; and no using Outputs to build a competing AI model where the model makers forbid it.

If these rules are broken, we may refuse requests, remove shared content, limit or suspend accounts, and report illegal activity to the authorities. The AI providers we use also apply their own usage rules.
