Analytics

If analytics is enabled, events may record that a tool was viewed or completed. Raw phone numbers, full addresses, salary values, and stay dates are not included in analytics events.

Advertising

Advertising is disabled by default. Before enabling it, consent and privacy requirements will be reviewed and ad placements will remain separate from tool controls and results.
