Acceptable Use Policy

1. Scope

This document is effective as of 11 October 2026.

This Policy applies to every Customer business and User of Yofatik CRM, including landing pages published with the Service and integrations through the API. It forms part of the Terms of Service issued by CMC Media Joint Stock Company.

The Service runs on shared infrastructure and connects to third-party platforms using the Provider's own apps and identifiers. Misuse by one account can lead a platform to restrict the whole system, so this Policy is enforced seriously.

2. Unlawful goods and content

Do not use the Service to advertise, sell or facilitate transactions in:

• Goods or services prohibited from trading under Vietnamese law;
• Counterfeit or infringing goods, or goods of unknown origin;
• Medicines, supplements, cosmetics and similar products advertised with false claims or without required licences;
• Content that opposes the State, incites violence, is pornographic, promotes gambling or fraud, defames others, or violates the Law on Cybersecurity 2018.

3. Messaging and customer care

• Do not send spam, unsolicited bulk messages, or promotional messages outside the time windows and purposes allowed by the platform's messaging policy.
• Do not impersonate another business, person or authority when replying to customers.
• Do not collect sensitive information (passwords, OTP codes, full card numbers) through messages.
• Do not harass or threaten end customers, including customers who refuse delivery.

4. End customers' personal data

• Only bring into the Service personal data you have a lawful basis to process.
• Do not buy, sell or swap customer lists, or export data for purposes other than those communicated to end customers.
• Grant staff only the access they need; use phone-number masking where staff do not need full numbers.
• Handle end customers' requests about their data promptly, as set out in the Data Processing Agreement.

5. Platform policies

When connecting a fanpage, ad account, carrier account or other service, the Customer must comply with that platform's terms — in particular Meta's Platform Terms, Messaging Policy and Advertising Policies. Do not use the Service to circumvent limits, review processes or restrictions a platform has applied to your account.

6. Landing pages and tracking

• Only publish landing pages on domains you are entitled to use.
• Do not embed malware, crypto-mining scripts, deceptive redirects or credential-harvesting forms.
• Do not display misleading prices or promotions; the displayed price must be the price the buyer will pay.
• Inform visitors and obtain consent for cookies and tracking codes as described in the Cookie Policy.

7. System integrity

• Do not scan for vulnerabilities, run penetration tests or denial-of-service attacks without our written consent.
• Do not attempt to access another business's data or bypass permission controls.
• Do not call the API at unreasonable rates or scrape data outside the provided API.
• Do not share partner API keys with unauthorised parties; revoke any exposed key immediately.

If you discover a security vulnerability, please report it to support@cmcmedia.com.vn as described on the Security page rather than disclosing it publicly.

8. Sharing and resale

Do not resell, sublicense, or share one business account among unrelated businesses unless you have a written reseller agreement with us.

9. Enforcement

Depending on severity, we may take one or more of the following steps:

1. A warning and a request to remedy within a set time;
2. Removing content, or suspending the affected landing page or connection;
3. Suspending a User account or the whole business;
4. Terminating the Service and providing information to competent authorities when lawfully required.

For serious or ongoing harm (fraud, malware, attacks on the system), action may be taken immediately and notified afterwards.

10. Reporting abuse

If you believe a landing page or account using Yofatik CRM breaches this Policy, send the link, a description and any evidence to support@cmcmedia.com.vn. We keep the reporter's identity confidential to the extent permitted by law.
