Amplitude に関するよくある質問（料金・導入・機能）

What is included in the Amplitude Free Starter plan? ▼

Amplitude offers a generous Free Starter plan covering up to 50,000 monthly tracked users (MTUs) with unlimited core product analytics, funnels, retention charts, and unlimited user seats at zero cost.

How does Amplitude differ from Google Analytics 4 (GA4)? ▼

While GA4 focuses primarily on web traffic acquisition and marketing channels, Amplitude specializes in deep digital product analytics—tracking exact user event sequences, onboarding drop-offs, and behavioral cohort retention inside logged-in apps.

How does Amplitude help reduce customer churn? ▼

Amplitude's retention analysis isolates behavioral cohorts (e.g. users who use feature X in week 1 vs those who don't), identifying the critical product 'aha moments' that prevent churn and increase lifetime customer value.

How does Amplitude handle data privacy and security? ▼

Amplitude is SOC 2 Type II certified, GDPR/CCPA compliant, and HIPAA eligible. It provides enterprise data governance tools to hash or exclude personally identifiable information (PII) before storage.
