Privacy Policy

Postal Server Integration For Mailster uses Appsero SDK to collect some telemetry data upon user’s confirmation. This helps us to troubleshoot problems faster & make product improvements.

Appsero SDK does not gather any data by default. The SDK only starts gathering basic telemetry data when a user allows it via the admin notice. We collect the data to ensure a great user experience for all our users.

Integrating Appsero SDK DOES NOT IMMEDIATELY start gathering data, without confirmation from users in any case.

Learn more about how Appsero collects and uses this data.
