2. How We Use Information

We process information to:

  2. Improve and develop features: analyze usage, test, troubleshoot, and enhance performance.
  3. Ensure security: detect fraud, spam, abuse, and security incidents.

  5. Marketing with consent: send newsletters or promotions; you can opt out any time.
  6. Comply with law: meet legal, tax, and regulatory obligations.

Legal bases (where the GDPR applies) include performance of a contract, legitimate interests, consent, and compliance with legal obligations.

3. Sharing and Disclosure

We do not sell or rent personal data. We may share information:

  • Service providers: payment processors, hosting, analytics, and customer support partners under contracts requiring confidentiality.
  • Business transfers: in connection with a merger, acquisition, or asset sale.
  • Legal requirements: to comply with subpoenas, court orders, or other lawful requests, or to protect rights, property, or safety.
  • With your consent: if you explicitly authorize disclosure.

4. International Transfers

Servers may be located in the United States and other countries. When we transfer personal data outside its country of origin, we rely on appropriate safeguards such as Standard Contractual Clauses or equivalent mechanisms to ensure adequate protection.

5. Data Retention

We keep personal data only as long as necessary for the purposes described in this Policy, including backups, dispute resolution, and compliance with legal obligations. Email content is retained until you delete it or your account terminates; backups may persist for up to 30 days.

Depending on your jurisdiction, you may have rights to:

  • Access, correct, or delete personal data.
  • Object to or restrict processing.
  • Port data in a structured, machine-readable format.
  • Withdraw consent at any time.
  • Lodge a complaint with a supervisory authority.

Submit requests by emailing privacy@messagescience.com or through account settings. We may verify your identity before responding.

Marketing Opt-Out

Click the "unsubscribe" link in promotional emails or adjust preferences in your account. Transactional and essential communications will still be sent.

7. Security

We employ industry-standard administrative, technical, and physical safeguards, including encryption in transit and at rest, role-based access controls, vulnerability management, and regular security audits. No method of transmission or storage is completely secure; we cannot guarantee absolute security.

8. Cookies and Tracking Technologies

We use:

  • Essential cookies: necessary for authentication and core functionality.
  • Preference cookies: remember settings such as language.
  • Analytics cookies: help us understand feature usage.
  • Third-party cookies: set by trusted partners for limited analytics or support.

You can disable cookies via browser settings, but parts of the Service may not function correctly.

9. Third-Party Links

The Service may contain links to third-party sites. We do not control and are not responsible for their privacy practices. Review their policies before providing information.

10. Changes to This Policy

We may update this Privacy Policy periodically. Material changes will be announced via email or an in-app notice at least 30 days before they take effect. Continued use after the effective date constitutes acceptance.
