Terms of Service

Last updated: June 2026
Effective: June 2026

1. Who we are, and what this agreement is

These Terms of Service ("Terms") are a binding agreement between you and:

ECHO PR COMPANY LIMITED
Company registration number 0105567094590
67/8, Mu 3, Chim Phli Sub-district, Taling Chan District, Bangkok 10170, Thailand
support@castorsocial.com

"Castor" is a trading name of ECHO PR COMPANY LIMITED. In these Terms, "Castor", "we", "us", and "our" mean ECHO PR COMPANY LIMITED. "You" means the person or organisation using the Services.

These Terms cover the Castor website at castorsocial.com, the Castor mobile applications, and all related services (the "Services").

By creating an account or using the Services, you accept these Terms. If you do not accept them, do not use the Services.

Our Privacy Policy forms part of these Terms.

2. Eligibility

To use Castor you must:

• Be at least 18 years old
• Have the legal capacity to enter into binding agreements
• If registering on behalf of a company, have authority to bind that company
• Not be barred from using the Services under the laws of Thailand or any other applicable jurisdiction
• Not have been previously removed from Castor

If you register on behalf of an organisation, "you" means both you and that organisation, and both are bound by these Terms.

3. Definitions

4. What Castor is, and what it is not

Castor is a marketplace. We provide the platform on which Brands and Creators find each other, agree terms, exchange content, and track published performance.

We are not a party to any Engagement. When a Brand and a Creator agree an Engagement, the resulting contract is between them. We are not the Creator's employer, agent, manager, or representative, and we are not the Brand's advertising agency. We do not control, direct, or supervise the work a Creator performs.

We do not guarantee outcomes. We do not promise that a Brand will find a suitable Creator, that a Creator will receive Applications or Engagements, that content will achieve any level of views or engagement, or that any party will perform its obligations.

We are not affiliated with any social media platform. Castor is an independent service. We are not endorsed by, sponsored by, or affiliated with TikTok, Instagram, Facebook, YouTube, or their operators. References to those platforms are for identification only, and all trade marks belong to their owners.

We do not currently process payments. Fees agreed under an Engagement are settled directly between the Brand and the Creator. We record the agreed amount for reference, but we do not hold, transmit, or guarantee any payment. If we introduce payment processing, we will update these Terms and notify you before it applies to you.

5. Your account

You must provide accurate information when registering and keep it current. You are responsible for all activity under your account, and for keeping your password secure. Tell us immediately at security@castorsocial.com if you believe your account has been compromised.

Do not share your account, transfer it to anyone else, or create an account on behalf of another person without their authority. One person or organisation may not maintain multiple accounts to circumvent these Terms.

6. Connecting social media accounts

You may connect social media accounts to Castor using each platform's official authorization process.

• We access Connected Accounts using OAuth authorization tokens issued by the platform. We never ask for, receive, or store your password or login credentials for any social media platform.
• We request read-only access. We do not post, comment, message, follow, like, or make any change to your Connected Account.
• We access only the data covered by the permissions you approve. Details are in our Privacy Policy.
• You may disconnect a Connected Account at any time, either in Castor under Settings → Social Integrations, or by revoking Castor's access from within the platform itself.
• Your use of each platform remains governed by that platform's own terms. You are responsible for complying with them, including TikTok's Terms of Service and Community Guidelines. Nothing in these Terms overrides them.
• Platforms may change or withdraw their APIs at any time. If that happens, features of Castor that depend on them may stop working. We are not liable for changes made by a platform.

7. Creator terms

If you use Castor as a Creator, you agree that:

• The Connected Accounts you link are yours, and you have the right to link them.
• Your profile, statistics, and portfolio are accurate and not artificially inflated.
• You will not acquire followers, views, likes, comments, or engagement by purchase, bots, engagement pods, or any artificial means. This applies to your account generally, not only to Castor Engagements. We may remove you permanently for breach.
• You will deliver work you have agreed to, on time, and to the specification in the Brief.
• You own or have licensed all rights in the content you deliver, including any music, footage, images, fonts, and the appearance of any person shown in it.
• Content you deliver does not infringe anyone's rights and does not breach any law.
• You will disclose paid partnerships as required (see section 10).
• You will not misrepresent a Brand's product, make claims about it that the Brand has not substantiated, or make claims prohibited by law.

You set your own rates and choose which Briefs to apply to. Nothing in these Terms creates an employment relationship, and you are responsible for your own taxes and any required registrations.

8. Brand terms

If you use Castor as a Brand or agency, you agree that:

• You have the right to promote the products or services in your Brief, and to grant the rights you ask Creators to grant.
• Your Brief accurately describes what you want, what you will pay, and how the content will be used.
• You will review and respond to Deliverables within the time stated on the platform.
• You will pay Creators the agreed fee, in full and on time, directly to the Creator.
• You will not ask a Creator to make claims that are false, unsubstantiated, or unlawful, or to omit a required disclosure.
• You will use Deliverables only within the scope of the licence agreed (see section 9). Using content beyond that scope — for example running paid media against an organic post, or continuing to use content after the licence expires — requires the Creator's separate agreement.
• If you are an agency, you are responsible for your client's compliance with these Terms.

9. Content and intellectual property

9.1 Creator content

Creators retain ownership of the content they create. Nothing in these Terms transfers copyright to Castor or to a Brand unless the parties separately agree it in writing.

9.2 Licence to the Brand

Unless the Brief and Application record something different, on delivery and payment the Creator grants the Brand a non-exclusive, worldwide licence to use the Deliverable on the Brand's own social media channels and website for twelve (12) months from delivery.

This default licence does not include: paid advertising or boosted posts, use in broadcast, print, or out-of-home media, sub-licensing to third parties, or modification beyond cropping and formatting. Those require express agreement between the Brand and the Creator, and normally an additional fee.

9.3 Licence to Castor

You grant Castor a non-exclusive, royalty-free licence to host, store, reproduce, and display your content and profile information solely to operate and provide the Services — for example, showing your media kit to Brands, delivering drafts, and reporting campaign performance. This licence ends when you delete the content or your account, except for copies retained in backups for the period set out in our Privacy Policy.

We may show your public profile and published campaign work in Castor marketing materials only with your prior written consent.

9.4 Castor's own property

The Services, including our software, design, and trade marks, belong to us. You may not copy, modify, reverse engineer, scrape, or create derivative works from the Services, or use automated means to extract data from them.

10. Advertising disclosure and legal compliance

Content created under an Engagement is commercial advertising. Both parties must comply with applicable law and platform rules, including:

• Thai consumer protection and advertising law, including the Consumer Protection Act B.E. 2522 and, where relevant, Thai FDA rules on advertising food, cosmetics, medical devices, and health products
• The disclosure rules of the platform where the content is published, including TikTok's branded content disclosure requirements
• Advertising standards in any other market the content is targeted at

Creators must clearly disclose paid partnerships. Brands must not ask Creators to conceal them. Neither party may make health, medical, or efficacy claims without the substantiation the law requires.

You are responsible for your own compliance. We do not review content for legal compliance, and providing the platform does not make us responsible for what is published on it.

11. Prohibited conduct

You must not:

• Impersonate anyone, or misrepresent your identity, affiliation, audience, or performance
• Provide false statistics, or manipulate engagement by any artificial means
• Post content that is unlawful, defamatory, harassing, hateful, obscene, or infringing
• Use the Services to distribute malware, spam, or unsolicited marketing
• Attempt to gain unauthorized access to the Services, other accounts, or our systems
• Scrape, crawl, or harvest data from the Services
• Circumvent, disable, or interfere with security or rate-limiting features
• Use the Services to build a competing product or service
• Breach the terms of any connected social media platform
• Use the Services for money laundering, fraud, or any unlawful purpose

Off-platform circumvention. If you meet a counterparty through Castor, you agree not to deliberately move that relationship off Castor to avoid our fees for twelve (12) months after first contact. This does not apply to parties you already had a working relationship with before joining.

12. Disputes between users

Disputes about an Engagement — quality, delivery, scope, or payment — are between the Brand and the Creator.

You should first try to resolve the dispute directly through Castor's messaging. If that fails, either party may ask us to review the matter at support@castorsocial.com. We may, at our discretion, look at the Brief, the messages, and the Deliverable and offer a non-binding view. We are not an arbitrator and our view does not bind either party. We may suspend accounts while a dispute is open.

13. Suspension and termination

By you. You may stop using the Services and delete your account at any time under Settings → Privacy → Delete account. Deleting your account does not end obligations under Engagements already agreed.

By us. We may suspend or terminate your account if you breach these Terms, if we are required to by law, if your conduct exposes us or other users to risk or liability, or if a social media platform requires it. Where it is reasonable and lawful to do so, we will give you notice and an opportunity to fix the problem first. For serious breaches — fraud, artificial engagement, unlawful content, security attacks — we may act immediately and without notice.

On termination: your right to use the Services ends. Sections 9, 11, 12, 14, 15, 16, 18, and 19 survive.

14. Disclaimers

The Services are provided "as is" and "as available". To the fullest extent permitted by law, we disclaim all warranties, express or implied, including any warranty of merchantability, fitness for a particular purpose, or non-infringement.

We do not warrant that the Services will be uninterrupted, secure, or error-free, that data or metrics displayed will be accurate or complete, or that any user is who they claim to be. Metrics are supplied by third-party platforms and we cannot verify their accuracy.

We do not vet, endorse, or guarantee any Brand or Creator. Use your own judgement before agreeing an Engagement.

15. Limitation of liability

To the fullest extent permitted by law:

• We are not liable for indirect, incidental, special, consequential, or punitive damages, or for loss of profit, revenue, data, goodwill, or business opportunity.
• We are not liable for the acts or omissions of any user, for any Engagement, for non-payment by a Brand, or for non-delivery by a Creator.
• Our total aggregate liability arising out of or relating to these Terms or the Services, for all claims combined, is limited to the greater of the total fees you have paid to Castor in the twelve (12) months before the claim arose, or THB 10,000.

Nothing in these Terms excludes liability that cannot lawfully be excluded, including liability for fraud, wilful misconduct, or death or personal injury caused by negligence.

16. Indemnity

You will indemnify and hold harmless ECHO PR COMPANY LIMITED and its directors, employees, and agents against claims, damages, losses, and reasonable costs arising from your use of the Services, your content, your breach of these Terms, your breach of any law or third-party right, or any dispute between you and another user.

17. Changes to the Services and these Terms

We may change or discontinue features of the Services. Where a change materially reduces functionality you rely on, we will give reasonable notice.

We may amend these Terms. For material changes, we will notify you by email and in the app at least fourteen (14) days before they take effect. If you do not accept the change, you may close your account before it applies. Continuing to use the Services after the effective date means you accept the amended Terms.

18. Governing law and jurisdiction

These Terms are governed by the laws of the Kingdom of Thailand, without regard to conflict of law rules.

Any dispute arising out of or in connection with these Terms is subject to the exclusive jurisdiction of the courts of Bangkok, Thailand. Nothing prevents either party from seeking urgent injunctive relief in any competent court.

19. General

Entire agreement. These Terms and the Privacy Policy are the entire agreement between us regarding the Services, replacing any earlier understanding.

Severability. If any provision is held unenforceable, the rest remains in force.

No waiver. Failing to enforce a provision is not a waiver of it.

Assignment. You may not assign these Terms without our written consent. We may assign them to an affiliate or to a buyer of our business, on notice to you.

Force majeure. Neither party is liable for failure to perform caused by events beyond its reasonable control.

Notices. We give notice by email to the address on your account, or in the app. You give notice to support@castorsocial.com.

Language. These Terms are written in English. If we publish a Thai translation and there is any inconsistency, the English version prevails.

Relationship. Nothing in these Terms creates a partnership, joint venture, employment, or agency relationship between you and us.
