EngageApp is an AI-native retention and lifecycle messaging product for small e-commerce and similar merchants. You pay per message successfully sent (prepaid credits), not a monthly fee per stored profile. This Privacy Policy explains how we collect, use, disclose, and safeguard information when you use EngageApp.

1. Information we collect

Account information. When you create an EngageApp account we collect information such as your name, email address, company or workspace name, and authentication credentials (password or equivalent).

Billing information. Prepaid credit purchases are processed by our payment partner(s) (currently Flutterwave on the live pricing flow). We do not store full payment card numbers.

Workspace and messaging data. To operate the service we process data you or your connected systems send to EngageApp, which may include:

  • Contact profiles (for example email, phone, external IDs, attributes you store)
  • Events (for example store checkouts, orders, custom events)
  • Campaigns, templates, segments, and delivery logs (channel, timestamps, status)
  • Integration credentials you connect (for example Shopify Admin API tokens, email/SMS/WhatsApp provider credentials), stored encrypted at rest where the product supports it

Usage and technical data. We collect logs needed to run and secure the product (IP address, device/browser metadata, API request metadata, error logs).

Cookies. We use essential cookies for authentication and session management on engageapp.xyz. We do not claim marketing analytics trackers on the marketing site unless they are actually installed.

2. How we use information

We use information to:

  • Provide, operate, and maintain EngageApp (campaigns, channels, integrations, analytics in-product)
  • Process prepaid credit purchases and related billing notices
  • Authenticate users, prevent abuse, and secure the platform
  • Communicate about service, security, and support
  • Improve reliability and product features
  • Comply with law

We do not sell personal information.

3. Roles: merchants vs end customers

If you are an EngageApp customer (merchant / workspace owner), you decide what contact and event data to send into EngageApp. For personal data of your end customers, you are typically the controller and EngageApp processes that data to provide the service. You must have a lawful basis and required consents for messaging (including SMS and WhatsApp where applicable).

4. Sharing and disclosure

We may share data with:

  • Delivery providers you configure (email, SMS, WhatsApp, push, or custom HTTP endpoints), limited to what is needed to send a message
  • Commerce and other integrations you connect (for example Shopify or WooCommerce webhooks and Admin API reads), limited to operating that connection
  • Infrastructure and payment processors that help us host and bill the service
  • Authorities when required by valid legal process

Third parties have their own policies. Review them for the providers you connect.

5. Retention

We retain account and workspace data while your account is active and as needed for billing, security, and legal compliance. Delivery and event logs are retained as needed to operate the product and resolve disputes. You may request deletion under our Data Deletion instructions.

6. Security

We use industry-standard measures including encryption in transit (TLS), access controls, and encryption of certain integration secrets at rest when configured. No method of transmission or storage is 100% secure.

7. Your rights

Depending on your jurisdiction, you may have rights to access, correct, delete, or export personal data, or to object to certain processing. Account owners can manage much of their workspace data in-product. To exercise rights, follow /data-deletion or email [email protected].

8. Children

EngageApp is not directed to children under 16. We do not knowingly collect personal information from children.

9. International transfers

We may process data in countries where we or our processors operate. Where required, we use appropriate safeguards.

10. Changes

We may update this policy. Material changes will be posted on this page with an updated date. Continued use after changes take effect means you accept the updated policy.
