New Feature / Enhancement Checklist

Current Limitation

There is no data source to estimate the common usage of Parse Server and its common configurations. That poses a challenge for strategic decision making in engineering and product management.

Feature / Enhancement Description

Anonymously collect analytics data about Parse Server usage. Similar to how Flutter SDK collects usage data:

The Flutter tool anonymously reports feature usage statistics and basic crash reports to help improve
Flutter tools over time. See Google's privacy policy: https://www.google.com/intl/en/policies/privacy/

https://github.com/flutter/flutter/blob/989f864497f59308896e8694c7d5d6a4ee65b36a/packages/flutter_tools/lib/src/reporting/first_run.dart#L15-L39

Characteristics:

• Analytics data is collected anonymously
• Parse Server provides a config option to disable the collection of analytics data (enabled by default)
• Log a message on server start-up if data collection is enabled
• Clearly describe the default data collection in the docs
• Don't run analytics already on package install; the disclaimer has to logged prior to data collection
• Publish privacy policy for Parse Platform org

3rd Party References

Flutter SDK

Start by reviewing the referenced Flutter analytics implementation and then trace Parse Server's startup and configuration entry points. Define the anonymous data, opt-out behavior, startup notice, documentation, and privacy-policy requirements before implementation; done means these requirements are specified and covered across the server and docs.
