Terms of Service

Last updated: [DATE]

These terms govern your use of Crown (the "Service"), operated by 디엔비소프트, a sole proprietorship registered in the Republic of Korea ("we", "us"). By creating an account or using the Service you agree to them.

1. The Service

An AI assistant for questions, tasks, documents and planning, used in our app or through our API. Replies are generated by artificial intelligence. They can be wrong, incomplete or out of date, and they are not legal, medical, financial or other professional advice. Check important facts and decisions yourself, or with a qualified professional, before relying on them.

2. Accounts and keys

• You sign in with Google or GitHub (email sign-in may be added). One account per person; you must be at least 14.
• You are responsible for activity under your account and your API keys. Keep keys secret; revoke a key in Settings if it is exposed.

3. Who sells the Service

Plans and credits are sold by Polar Software, Inc. ("Polar"), our reseller and merchant of record. Polar processes payment, issues receipts and handles sales tax, under the Polar Checkout Buyer Terms. Prices include tax. We never see your card details.

4. Plans, credits and refunds

• Plans are monthly subscriptions that renew automatically at the price shown at checkout, every month, until you cancel. Cancel at any time in Settings → Manage billing; the plan stays active until the end of the month you paid for and does not renew. We will tell you at least 30 days before a price change takes effect on your renewal.
• Each plan includes a monthly usage allowance, shown as a percentage in the app. Each reply uses part of it, depending on its length and depth. Unused allowance does not carry over to the next month.
• Credits are bought separately, do not expire, and are used only after the month's plan allowance (or without a plan).
• A reply that fails is not charged.
• Withdrawal. Within 7 days of purchase you can cancel a plan or credits you have not used yet, for a full refund. Once you start using them — by sending a message — the service has started and you cannot withdraw for change of mind for what was used; you agree to this before paying. Polar, as the seller, may also grant refunds under its own policy.
• If the Service does not work as described — for example it is unavailable for a long period, or a plan's features are not provided — you can ask for a refund within 3 months of the problem or 30 days after you noticed it, whichever ends later.
• An answer you disagree with, or that turns out to be wrong, is not by itself a reason for a refund (see section 1).
• Accepted refunds are issued within 3 business days through Polar.

5. Your content

• You keep your rights in what you send and, to the extent the law allows, in the replies you receive. You are responsible for having the right to send what you send.
• We store your chats so you can see them again, and process them only to provide the Service. We do not use your chats to train AI models, and we do not sell them. Delete a chat or your account at any time (see the Privacy Policy).

6. Acceptable use

Do not use the Service to break the law; to harm, harass or deceive people; to create malware or attack systems; to generate sexual content involving minors; to try to extract the system's instructions or circumvent its limits or safety measures; or to resell access without our permission. You must also follow the usage policies of the AI model providers that power the Service, including the Anthropic Usage Policy. We may refuse requests, and suspend or close accounts that break these rules; a paid period cut short for that reason is not refunded unless the law requires it.

7. Availability and changes

We aim to keep the Service available but do not guarantee uninterrupted operation. We may change features. If we stop the Service, we refund the unused part of the current paid month and unused credits.

8. Liability

To the extent permitted by law, the Service is provided "as is", and our total liability for any claim is limited to what you paid us in the 3 months before the claim. We are not liable for indirect or consequential losses, including losses from relying on a reply. Nothing here limits liability for intent or gross negligence, or your rights as a consumer under the law of your country.

9. Changes to these terms

We may update these terms and will announce material changes in the app at least 7 days before they apply (30 days for anything that affects what you pay). If you do not agree, you can cancel before they apply.

10. Law and contact

These terms are governed by the laws of the Republic of Korea, without prejudice to mandatory consumer protection laws of your country.
