Terms of Service

Last updated: February 11, 2026

1. Agreement to Terms

By accessing or using MoltFlow ("Service"), operated by WaiFlow ("we," "us," or "our"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree to these Terms, you may not access or use our Service.

These Terms constitute a legally binding agreement between you and WaiFlow. Please read them carefully before using our Service.

2. Critical: Third-Party Dependencies & API Disclaimer

⚠️ IMPORTANT: MoltFlow does NOT use the official WhatsApp Business API or Meta Business Platform.

MoltFlow uses an unofficial, third-party implementation to connect with WhatsApp. This is NOT endorsed, certified, or supported by Meta, WhatsApp, or any affiliated company.

MoltFlow is built on top of third-party services that we do not own, control, or operate.

WhatsApp (Meta Platforms, Inc.)

MoltFlow interacts with WhatsApp, a service owned and operated by Meta Platforms, Inc. We have no affiliation, partnership, or endorsement from WhatsApp or Meta. WhatsApp may change its terms, policies, or technical implementation at any time without notice to us.

WAHA (WhatsApp HTTP API) - Unofficial Protocol

MoltFlow utilizes WAHA (WhatsApp HTTP API), an open-source project that provides programmatic access to WhatsApp through the unofficial WhatsApp Web protocol. This is NOT the official WhatsApp Business API. WAHA is a third-party project that we do not control. Changes to WAHA, its availability, or its compatibility with WhatsApp may directly impact MoltFlow's functionality.

Not Official Meta Business Platform

Unlike the official WhatsApp Business API (provided through Meta Business Platform), MoltFlow's connection method is not officially supported. This means: (1) No guaranteed uptime or SLA from Meta; (2) Potential for service disruption without warning; (3) Higher risk of account restrictions compared to official API users; (4) No direct support from Meta/WhatsApp for technical issues.

YOU EXPRESSLY ACKNOWLEDGE AND AGREE THAT:

  • MoltFlow's functionality depends entirely on WhatsApp and WAHA remaining operational and compatible.
  • We cannot guarantee uninterrupted service if WhatsApp or WAHA changes their systems.
  • We are not responsible for any service disruption caused by WhatsApp, WAHA, or any third-party dependency.
  • Your use of MoltFlow is at your own risk regarding these third-party dependencies.
  • We may be forced to discontinue the Service entirely if WhatsApp or WAHA becomes unavailable or incompatible.

3. WhatsApp Policy Compliance

You are solely and entirely responsible for ensuring that your use of MoltFlow complies with:

  • WhatsApp's Terms of Service
  • WhatsApp Business Policy
  • WhatsApp Commerce Policy
  • Meta's Community Standards
  • All applicable local, national, and international laws

Prohibited Activities:

  • Spam: Sending unsolicited bulk messages or automated messages to users who have not opted in.
  • Harassment: Using the Service to harass, threaten, or abuse others.
  • Fraud: Phishing, scams, impersonation, or any deceptive practices.
  • Malware: Distributing viruses, malicious code, or harmful content.
  • Illegal Content: Any content that violates applicable laws.
  • Privacy Violations: Collecting or processing personal data without proper consent.
  • Circumvention: Attempting to bypass WhatsApp's security measures or rate limits.

ACCOUNT SUSPENSION DISCLAIMER:

WhatsApp actively monitors for policy violations and may ban or suspend accounts at their sole discretion. WE ARE NOT RESPONSIBLE IF YOUR WHATSAPP ACCOUNT IS BANNED, SUSPENDED, OR TERMINATED due to your use of MoltFlow or for any other reason. You use MoltFlow and connect your WhatsApp account entirely at your own risk.

4. Anti-Spam Guidelines

MoltFlow has a zero-tolerance policy for spam. You must comply with all anti-spam laws and WhatsApp policies.

Required Practices:

  • Opt-in Only: Only message users who have explicitly consented to receive messages from you.
  • Easy Opt-out: Provide a clear and immediate way for recipients to unsubscribe.
  • Message Limits: Respect rate limits and avoid excessive messaging frequency.
  • Accurate Sender Info: Clearly identify yourself or your business in all messages.
  • Relevant Content: Only send content relevant to what users opted in for.

Strictly Prohibited:

  • Purchasing or using contact lists without verified consent
  • Sending messages to users who have not explicitly opted in
  • Ignoring or delaying unsubscribe requests
  • Using deceptive subject lines or content
  • Harvesting phone numbers from public sources
  • Automated mass messaging without rate limiting
  • Sending messages outside reasonable business hours without consent

VIOLATION CONSEQUENCES:

Violations of anti-spam policies will result in immediate account suspension or termination without refund. We may also report violations to WhatsApp and relevant authorities.

5. Message Processing & AI Usage

MoltFlow processes messages using artificial intelligence and automated systems. By using our Service, you acknowledge and consent to the following:

How We Process Messages:

  • Message Storage: A preview of each message (first 500 characters) is stored to enable delivery tracking, conversation history, and feature functionality. Full message content is not retained.
  • AI Analysis: Messages may be analyzed by AI for features like auto-responses, lead detection, sentiment analysis, and smart labeling.
  • Third-Party AI (OpenAI): When AI-powered features are enabled, message content is sent to OpenAI (San Francisco, CA, USA) for processing. OpenAI acts as a sub-processor under contractual data protection obligations. Data may be transferred to the United States under Standard Contractual Clauses.
  • Style Training: If you enable Learn Mode, your outbound messages are analyzed to extract statistical writing patterns (word frequency, formality score, emoji usage). Only aggregate statistics are stored in your style profile, not the original message text.
  • Knowledge Base (RAG): Documents you upload to the knowledge base are chunked, embedded as vectors, and stored for retrieval-augmented generation. Document text is stored alongside embeddings to provide context to AI responses.
  • Metadata Processing: Message timestamps, read receipts, and delivery status are processed for analytics and delivery tracking.

Data Retention:

  • Message previews: Automatically deleted after 90 days from the date of the message.
  • Message metadata (timestamps, delivery status): Retained for up to 1 year for analytics purposes.
  • AI audit logs: Retained for 90 days.
  • Knowledge base documents: Retained until you delete them or your account is terminated.
  • Style profiles: Retained until you delete them or your account is terminated.
  • Collected reviews: Retained for 90 days, then automatically deleted.
  • Backups: Deleted messages may persist in database backups for up to 30 days.
  • Analytics: Aggregated, anonymized analytics data may be retained indefinitely.

Your Responsibilities as Data Controller:

When you use MoltFlow to process messages from your contacts, you act as the Data Controller for your contacts' personal data, and MoltFlow acts as your Data Processor. You are responsible for:

  • Informing your contacts that their messages are processed by MoltFlow and may be analyzed by AI systems
  • Providing your contacts with access to MoltFlow's Privacy Policy
  • Obtaining necessary consents for AI processing where required by applicable law
  • Handling data subject requests (access, erasure, portability) from your contacts
  • Not sending sensitive personal data (health, financial, legal) through the Service without appropriate safeguards
  • Complying with GDPR, CCPA, and all other applicable data protection laws in your jurisdiction

AI DISCLAIMER:

AI-generated responses and analysis are provided for convenience and may contain errors. You are solely responsible for reviewing and approving any automated messages before they are sent. We are not liable for any damages arising from AI-generated content.
