- = GDPR =
87
-
88
- The Newsletter Plugin provides all the technical tools needed to achieve GDPR compliancy and we're continuously working to improve them and to give support even for specific use cases.
89
- The plugin does not collect users' own subscribers data, nor it has any access to those data: hence, we are not a data processor, so a data processing agreement is not needed.
90
- Anyway if you configure the plugin to use external services (usually an external mail delivery service) you should check with that service if some sort of agreement is required.

+ = GDPR =
87
+
88
+ The Newsletter Plugin provides all the technical tools needed to achieve GDPR compliancy and we're continuously working to improve them and to give support even for specific use cases.
89
+ The plugin does not collect users' own subscribers data, nor it has any access to those data: hence, we are not a data processor, so a data processing agreement is not needed.
90
+ Anyway if you configure the plugin to use external services (usually an external mail delivery service) you should check with that service if some sort of agreement is required.
91
+
92
+ = Support =
93
+
94
+ We provide support for our plugin on [Wordpress.org forums](https://wordpress.org/support/plugin/newsletter) and through our [official forum](https://www.thenewsletterplugin.com/forums).
