Terms of Service

Last updated: February 23, 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 & WhatsApp Disclaimer

⚠️ IMPORTANT: READ THIS SECTION CAREFULLY BEFORE USING MOLTFLOW.

MoltFlow is NOT affiliated with, endorsed by, certified by, or in any way officially connected with WhatsApp, Meta Platforms, Inc., or any of their subsidiaries or affiliates. The name "WhatsApp" as well as related names, marks, emblems, and images are registered trademarks of their respective owners.

MoltFlow relies on third-party services and platforms that we do not own, control, or operate.

WhatsApp Integration

MoltFlow connects to WhatsApp using proprietary integration technology. This is NOT the official WhatsApp Business API provided through the Meta Business Platform. Our integration method is unofficial and is not endorsed, supported, or guaranteed by Meta or WhatsApp. WhatsApp may change its terms, policies, security measures, or technical implementation at any time without notice, which may directly impact MoltFlow's functionality, availability, or your ability to use the Service.

No Official Partnership with Meta

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

Account Risk Acknowledgment

By using MoltFlow, you acknowledge that connecting your WhatsApp account to any third-party service carries inherent risk. WhatsApp actively monitors accounts for unusual activity, policy violations, and unauthorized third-party access. MoltFlow does NOT guarantee that your WhatsApp account will not be banned, suspended, restricted, or permanently terminated. No WhatsApp automation platform can guarantee 100% account safety. You use MoltFlow and connect your WhatsApp account entirely at your own risk.

YOU EXPRESSLY ACKNOWLEDGE AND AGREE THAT:

  • MoltFlow's functionality depends on the continued availability and compatibility of WhatsApp and our integration technology.
  • We cannot guarantee uninterrupted service if WhatsApp changes its systems, policies, or enforcement practices.
  • We are not responsible for any service disruption caused by WhatsApp, Meta, or changes to their platform.
  • Your WhatsApp account may be banned, suspended, or terminated as a result of using MoltFlow or any similar automation tool, and we bear no liability for such outcomes.
  • Your use of MoltFlow is at your own risk regarding third-party dependencies and account safety.
  • We may be forced to modify, suspend, or discontinue the Service entirely if our integration with WhatsApp becomes unavailable or incompatible.
  • You are solely responsible for maintaining backups of your WhatsApp data and contacts.

3. WhatsApp Policy Compliance & Account Risk

You are solely and entirely responsible for ensuring that your use of MoltFlow complies with all applicable WhatsApp and Meta policies, including but not limited to:

  • WhatsApp Terms of Service (whatsapp.com/legal/terms-of-service)
  • WhatsApp Business Messaging Policy
  • WhatsApp Commerce Policy
  • Meta Community Standards
  • All applicable local, national, and international laws including but not limited to GDPR, CCPA, CAN-SPAM, TCPA, ePrivacy Directive, and equivalent legislation in your jurisdiction

Prohibited Activities:

  • Spam & Unsolicited Messaging: Sending unsolicited bulk messages, automated messages to users who have not opted in, or messages that recipients have not consented to receive.
  • Harassment & Abuse: Using the Service to harass, threaten, intimidate, stalk, or abuse any individual or group.
  • Fraud & Deception: Phishing, scams, social engineering, impersonation of individuals or organizations, or any deceptive practices.
  • Malware & Harmful Content: Distributing viruses, trojans, ransomware, spyware, malicious links, or any harmful content.
  • Illegal Content & Activities: Any content or activity that violates applicable laws, including promotion of illegal goods or services.
  • Privacy Violations: Collecting, harvesting, or processing personal data without proper legal basis and informed consent.
  • Circumvention: Attempting to bypass WhatsApp's security measures, rate limits, or account restrictions using the Service or any other means.
  • Reselling or Sublicensing: Reselling, sublicensing, or providing MoltFlow access to third parties without authorization.
  • Reverse Engineering: Reverse engineering, decompiling, or attempting to extract the source code of the Service or its integration technology.
  • Automated Account Creation: Using the Service to create WhatsApp accounts or to automate WhatsApp account registration.
  • Excessive Load: Intentionally generating excessive load on the Service or using it in a manner that degrades performance for other users.

ACCOUNT SUSPENSION & BAN DISCLAIMER:

WhatsApp actively monitors accounts for policy violations, unusual activity, and unauthorized third-party access. WhatsApp may ban, suspend, restrict, or permanently terminate accounts at their sole discretion and without prior notice. MOLTFLOW IS NOT 100% BAN-SAFE. NO WHATSAPP AUTOMATION PLATFORM CAN GUARANTEE THAT YOUR ACCOUNT WILL NOT BE BANNED.

WE ARE NOT RESPONSIBLE IF YOUR WHATSAPP ACCOUNT IS BANNED, SUSPENDED, RESTRICTED, OR PERMANENTLY TERMINATED due to your use of MoltFlow, your messaging practices, WhatsApp's enforcement actions, or for any other reason. You use MoltFlow and connect your WhatsApp account entirely at your own risk. We strongly recommend:

  • Not connecting your primary personal WhatsApp number
  • Maintaining backups of important contacts and conversations
  • Following all WhatsApp policies and best messaging practices
  • Starting with low message volumes and gradually increasing
  • Monitoring your account health and adjusting behavior if you receive warnings

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

Bulk Messaging & Campaign Responsibilities:

  • You are solely responsible for the content of all bulk messages and campaigns sent through MoltFlow.
  • MoltFlow applies anti-spam rate limiting (delays between messages) to protect your account, but this does not guarantee account safety.
  • Sending bulk messages to contacts who have not opted in is a violation of these Terms, WhatsApp policies, and may violate applicable laws.
  • Campaign analytics (delivery, read, reply, reaction tracking) rely on WhatsApp's delivery infrastructure and may not always be accurate or complete.

Scheduled Messages:

  • Scheduled and recurring messages are executed automatically at the configured time. You are responsible for the content and timing of all scheduled messages.
  • We do not guarantee exact delivery times. Scheduled messages may be delayed due to system load, WhatsApp availability, or queue processing.
  • If your WhatsApp session is disconnected at the scheduled time, messages will fail and may not be automatically retried.

Group Monitoring & Lead Detection:

  • Group monitoring features observe messages in WhatsApp groups you are a member of. You must comply with the group's rules and WhatsApp's policies regarding group participation.
  • Lead detection uses AI analysis and may produce false positives or false negatives. You should independently verify all detected leads.
  • You are responsible for ensuring that any outreach to detected leads complies with applicable anti-spam and privacy laws.

AI DISCLAIMER:

AI-generated responses, lead scores, sentiment analysis, transcriptions, and all other AI-powered features are provided for convenience and may contain errors, inaccuracies, or inappropriate content. AI features are powered by OpenAI and are subject to OpenAI's capabilities and limitations. You are solely responsible for reviewing, approving, and supervising any automated or AI-generated messages before and after they are sent. We are not liable for any damages, losses, missed opportunities, or adverse outcomes arising from AI-generated content, incorrect lead scoring, inaccurate sentiment analysis, or any other AI output.
