Is Salesforce Tool Suite safe?

This extension provides Salesforce administration tools for reports, debug logs, schemas, events, and bulk management.

It helps Salesforce administrators and developers compare profiles and permission sets, export metadata, view and tail debug logs, explore schemas, build SOQL queries, and manage Salesforce records. It also supports event log downloads, Apex test execution, object limit checks, and bulk management of items such as validation rules, workflow rules, fields, objects, reports, dashboards, flows, and record types. The store description says data is stored exclusively on the local machine.
