1. Controller

The operator of this Service ("we", "us", "our") is the provider of the WhatsApp Messaging API in this repository. For questions about this Privacy Policy or to exercise your rights, contact us at the email above.

2. Information We Collect

  • Account & Registration Data: name, email, phone number, API key registrations, and other account-related details you provide.
  • Message Metadata: timestamps, message IDs, sender/recipient phone numbers and identifiers, and routing metadata needed to deliver messages through WhatsApp (we do not access the content of end-to-end encrypted messages unless you explicitly provide it to our systems).
  • Usage & Diagnostics: API usage logs, request/response metadata, IP addresses, device and browser identifiers, server logs, error reports, and performance metrics.
  • Payment & Billing: if applicable, billing identifiers and payment transaction records (collected and processed by our payment provider).
  • Cookies & Tracking: cookies and similar technologies used for analytics and to maintain sessions if you access a web dashboard.

3. How We Use Information

We use collected information to:

  • Provide, operate, and maintain the Service
  • Process API requests and deliver messages
  • Authenticate and authorize users and API clients
  • Monitor, analyze, and improve system performance and reliability
  • Detect, prevent, and respond to security incidents and abuse
  • Fulfill legal obligations and comply with law enforcement requests
  • Communicate updates, support, and administrative messages

4. Sharing & Disclosure

We may share information with:

  • Service Providers: vendors that provide hosting, analytics, email delivery, payment processing, and other infrastructure services.
  • Third-party Integrations: WhatsApp, RapidAPI, and other platforms you connect through the Service to deliver messages. Those providers have their own policies.
  • Legal & Safety: law enforcement, regulators, or other third parties as required to comply with legal obligations or to protect rights, property or safety.
  • Business Transfers: in the event of a merger, acquisition, reorganization, or sale of assets, user information may be transferred as part of the transaction.

We do not sell personal information for monetary consideration.

5. Data Retention

We retain information as long as necessary to provide the Service, comply with legal obligations, resolve disputes, enforce agreements, and for internal analytics. Retention periods vary by data type; if you need details or request deletion, contact us at the address above.

6. Security

We implement organizational and technical measures designed to protect information from unauthorized access, disclosure, alteration, and destruction. No system is completely secure; we cannot guarantee absolute protection. Promptly report suspected breaches to support@retentionstack.agency.

7. International Transfers

Data may be processed or stored in countries other than your home country. By using the Service you consent to transfers to jurisdictions that may have different data protection laws.

8. Your Rights & Choices

Depending on your jurisdiction, you may have rights including access, correction, deletion, restriction, objection to processing, and data portability. To exercise these rights or to object to processing, contact us at support@retentionstack.agency. We will respond according to applicable law.

You can also:

  • Revoke API keys or delete your account from the Service dashboard (if available).
  • Opt out of marketing emails by following unsubscribe instructions in those messages.

9. Children

The Service is not directed to children under 16 (or a higher age where required). We do not knowingly collect personal information from children. If you believe we have collected such data, contact us to request deletion.

10. Third-Party Sites & Links

The Service may contain links to third-party websites and services. We are not responsible for the privacy practices or content of third parties. Review the privacy policies of any third-party service you use.

11. Relationship to Terms of Use

These practices are additional to the Terms of Use. The Terms of Use define permitted activities and disclaimers related to WhatsApp integration; this Privacy Policy explains data handling and user rights. You remain responsible for complying with WhatsApp's policies when using the Service.

12. Changes to This Policy

We may update this Privacy Policy from time to time. We will post the updated policy with a revised "Last Updated" date. Continued use of the Service after changes indicates acceptance of the updated policy.
