The agreement covering plans, processing, and billing

1. Service overview

Control Beat Co., Ltd. (주식회사 컨트롤비트), business registration number 526-88-03467 and mail-order sales registration 2025-서울관악-0809, provides NULX from its registered office at 3F, Room J221, 408-1 Bongcheon-ro, Gwanak-gu, Seoul, Republic of Korea. NULX provides video upload, storage, processing, playback, and management for business teams. A free account without connected storage uses NULX-managed storage; when customer storage is connected, supported files are kept with that provider.

2. Accounts and access

You must be at least 18 or the age of legal majority where you live. Account information must be accurate, and a person acting for an organization must have authority to enter the agreement and direct the relevant data processing. Keep the account, email, API keys, and public or private settings secure and report suspected access promptly.

3. Customer content and limited license

Customers retain their rights in content. You grant NULX a non-exclusive license, limited to storing, copying, processing, and transmitting content as needed to provide the service. The license ends when the content is deleted, except for legally retained records and valid backups. You must have the necessary rights and consents and must not upload unlawful, infringing, malicious, or service-disrupting material.

4. Publication settings and credentials

Customers must review video visibility, allowed embed domains, storage permissions, and API-key scope. NULX cannot decide on a customer's behalf whether a public link or permission is appropriate. This does not shift liability for NULX's willful misconduct, gross negligence, or non-waivable legal duties to the customer.

5. Fees and plan limits

Some services are paid. Public plans show monthly included encoding and storage-connection limits on the pricing page and in account settings. Automatic captions are metered by source-video duration when enabled. Customers may configure HMAC-signed webhook endpoints for upload and transcoding events.

6. Plan changes

Start a supported paid plan from Billing after signing in. Existing subscribers can manage their card and cancellation through the billing portal. Contact billing for a plan change; the amount and effective date are confirmed before the change is applied.

7. Payment failure and account status

A failed subscription payment may suspend new uploads until payment is confirmed. Separate usage invoices become overdue 14 days after finalization and may suspend new uploads after a further 7 days. A past-due status alone does not stop existing playback. Uploads resume once outstanding payment requirements are resolved.

8. Billing, cancellation, and refunds

Public-plan charges combine the plan fee, video processing beyond included hours, and automatic-caption usage you enable. Your storage or delivery provider bills its own costs directly; those costs are not added to the NULX statement. To speed up review, report a billing error through /contact within 30 days of the statement. If an error, failure to provide the service, misdelivery, or another legally recognized refund ground is confirmed, the refund is made to the original payment channel or by bank transfer. The 30-day reporting request and 60-day statement-dispute window do not limit statutory cancellation, refund, or damages rights. Subscription cancellation timing and any remaining period follow the conditions shown before payment or a separate agreement. Closing the payment page, or a declined card, does not create a charge.

9. Account cancellation and data deletion

You can cancel the account from account settings. Cancellation stops new uploads and write actions but does not automatically delete data. Submit a separate request through /contact for deletion; after owner verification, it is completed within 30 days. Take down public embeds before cancellation if they must stop immediately. Video in a free account without connected storage is moved to Trash after 90 inactive days and prior notice, then deleted after another 30 days.

10. External services and backups

Storage, delivery, payment, email, sign-in, and caption providers selected or used for the service are subject to their own terms, fees, and incidents. Customers are responsible for separate backups of important originals and outputs and for permissions and costs in their external accounts. NULX investigates and restores incidents within its control but does not guarantee a third party's availability or a customer's configuration.

11. Restriction and suspension

NULX may restrict only the necessary features or account access when there is a security risk, unlawful or infringement report, service disruption, nonpayment, or a terms violation. Unless an urgent security or legal reason prevents it, we explain the reason and recovery path. Submit an appeal through /contact.

12. Service and terms changes

We provide advance notice on the site or by registered email for material changes to features, fees, or these terms. A change needed immediately for security or legal compliance is explained afterward where practical. If the service is discontinued, we provide a reasonable period and method for export or deletion.

13. Availability and liability

NULX does not currently offer a formal uptime SLA or service credits. We operate the service with reasonable care and work to restore incidents. Force majeure and external failures beyond reasonable control are considered to the extent they caused the impact, but these terms do not exclude liability for willful misconduct, gross negligence, or rights that applicable law does not allow us to waive.

14. Contract formation and document priority

Creating a free account does not start a paid service. A paid plan begins after price, payment timing, and cancellation conditions are shown and a subscription payment is approved or a separate agreement is signed. If a signed order form or separate agreement conflicts with these terms, that document controls only for the conflicting scope, and mandatory legal rights remain in effect.

15. NULX intellectual property

NULX, its software, documentation, designs, and trademarks remain the property of Control Beat Co., Ltd. or its licensors. These terms grant only the limited, revocable right to use the service during the account term. You may not copy, resell, reverse engineer, bypass access controls, or use the service to build a competing product except where applicable law expressly permits it.

16. Third-party claims caused by customer use

To the extent permitted by law, a business customer will defend and indemnify Control Beat Co., Ltd. against a third-party claim, penalty, or reasonable cost to the extent caused by the customer's content, unlawful use, infringement of another person's rights, or material breach of these terms. NULX must provide prompt notice and reasonable control of the defense. This section does not cover loss caused by NULX's own breach, willful misconduct, gross negligence, or non-waivable legal duty.

17. Governing law, disputes, and language

These terms are governed by the laws of the Republic of Korea, without overriding mandatory consumer protections that apply where you live. The Seoul Central District Court has non-exclusive jurisdiction to the extent permitted by law; a mandatory consumer forum remains available. Contact us first at contact@nulx.dev so we can try to resolve a dispute promptly. English is the primary operational version for international use, but a signed order form and mandatory law control if a translation conflicts.
