2.2. Subscriber and Campaign Information

Send Onyx enables customers to manage subscriber lists, create email campaigns, and integrate email delivery services.

Depending on how you use the Service, information processed through your account may include:

3. How We Use Information

We may use the information we collect for the following purposes:

To create, maintain, and administer customer accounts.

We do not use customer subscriber lists for our own independent marketing purposes simply because those lists are uploaded to Send Onyx.

4. Email Delivery, Tracking, and Third-Party Providers

4.1. Email Delivery Services

Send Onyx may allow customers to connect external SMTP servers or third-party email delivery providers.

When a customer sends an email campaign, relevant information may be transmitted to the configured provider to facilitate delivery. This information may include recipient email addresses, sender details, message content, and technical delivery information.

The processing, storage, and use of this information by the external provider are also governed by that provider's policies and terms.

Customers are responsible for reviewing the terms and privacy practices of the email delivery services they choose to integrate.

4.2. Email Tracking

Depending on the features enabled by a customer, Send Onyx may process email open events, link clicks, delivery events, and other campaign engagement metrics.

Open tracking may use tracking pixels or similar technologies. Click tracking may use redirect links or tracking domains to record interactions with campaign links.

These technologies may allow customers to evaluate campaign performance and create engagement-based segments.

Tracking accuracy may be affected by email clients, privacy protections, automated security scanners, image-blocking settings, and other technical factors. Accordingly, engagement statistics may not always reflect actual human behavior.

Customers are responsible for providing any notices, obtaining any consent, and honoring any opt-out rights required by applicable law when using email tracking features.

4.3. Third-Party Integrations

The Service may support integrations with third-party tools, payment processors, analytics providers, email delivery services, and other external platforms.

When you enable an integration, relevant information may be shared with the applicable provider as necessary to provide the requested functionality.

We are not responsible for the independent privacy practices of third-party providers. We encourage you to review their privacy policies before connecting their services.

5. Cookies and Similar Technologies

We may use cookies and similar technologies to operate our website and Service, maintain sessions, remember preferences, improve functionality, analyze usage, and support security.

Cookies may include:

Essential cookies: Required for authentication, account sessions, security, and core website functionality.
Preference cookies: Used to remember settings and preferences.
Analytics cookies: Used, where implemented, to understand website usage and improve performance.

You can manage cookies through your browser settings and, where available, our cookie preference controls. Disabling certain cookies may prevent some features from working correctly.

Where required by applicable law, we will seek consent before using non-essential cookies or similar technologies.

Email tracking technologies used in campaigns are addressed separately in the Email Delivery, Tracking, and Third-Party Providers section above.

6. Legal Bases for Processing

Where applicable data protection laws require a legal basis for processing personal information, we may rely on one or more of the following:

Contract: Processing necessary to provide the Service, manage accounts, or fulfill contractual obligations.
Legitimate interests: Processing necessary to secure, maintain, troubleshoot, and improve the Service, prevent abuse, and protect our business, provided those interests are not overridden by applicable rights.
Consent: Processing based on consent where required, including certain marketing communications or uses of cookies and tracking technologies.
Legal obligations: Processing necessary to comply with applicable laws, regulations, legal proceedings, or lawful requests.

Where processing is based on consent, you may withdraw that consent as permitted by applicable law. Withdrawal does not affect the lawfulness of processing carried out before withdrawal.

7. How We Share Information

We do not sell personal information to third parties in exchange for money.

We may disclose information in the following circumstances:

7.1. Service Providers

We may share information with service providers that help us operate our business, including providers of hosting, infrastructure, payment processing, customer support, security, analytics, and email delivery services.

These providers may process information only as necessary to perform their services for us, subject to applicable contractual and legal requirements.

7.2. Customer-Directed Sharing

Information may be transferred to third-party services that a customer chooses to connect to Send Onyx, including external SMTP servers and email delivery providers.

7.3. Legal Requirements

We may disclose information when reasonably necessary to comply with applicable law, a court order, subpoena, or other valid legal process, or when disclosure is otherwise legally permitted.

7.4. Protection of Rights and Security

We may disclose information where reasonably necessary to investigate suspected fraud, enforce our Terms and Conditions, protect the security of the Service, or protect the rights, safety, or property of Send Onyx, our customers, or others.

7.5. Business Transfers

Information may be transferred as part of a merger, acquisition, financing, restructuring, sale of assets, or similar business transaction, subject to applicable legal requirements.

7.6. With Your Consent

We may disclose information for other purposes when you direct us to do so or provide the required consent.

8. International Data Transfers

Send Onyx and its service providers may process information in countries other than the country where you reside.

Those countries may have data protection laws that differ from the laws in your jurisdiction.

Where required by applicable law, we will implement appropriate safeguards for international transfers of personal information, such as applicable standard contractual clauses or other legally recognized transfer mechanisms.

9. Data Retention

We retain personal information for as long as reasonably necessary to provide the Service, maintain customer accounts, fulfill contractual obligations, resolve disputes, enforce agreements, comply with legal requirements, and protect our legitimate business interests.

Retention periods may vary depending on the type of information and the purpose for which it is processed.

Subscriber records, campaign information, delivery logs, and tracking statistics may remain within a customer's account until deleted by the customer, removed through available account functionality, or otherwise handled in accordance with applicable retention requirements and our operational policies.

Certain information may be retained for a longer period where necessary for legal compliance, fraud prevention, security, accounting, or dispute resolution.

When information is no longer required, we will take reasonable steps to delete it or anonymize it, subject to applicable law and legitimate retention requirements.

10. Data Security

We take reasonable technical and organizational measures designed to protect personal information against unauthorized access, disclosure, alteration, loss, or destruction.

These measures may include access controls, authentication safeguards, infrastructure security, and monitoring for suspicious activity.

However, no method of transmission over the Internet or electronic storage is completely secure. We cannot guarantee absolute security.

You are responsible for maintaining the confidentiality of your account credentials, securing your connected email delivery accounts, and notifying us promptly if you suspect unauthorized access to your Send Onyx account.
