Data held only on your device is removed when you uninstall the app.

Data that is retained, and for how long

Data	Why	Retention
Anonymized analytics and crash logs (Firebase)	Cannot be linked back to you once the account is gone; retained by Google and deleted automatically	Up to 14 months (analytics) / 90 days (crash logs)
Payment and transaction records	Held by Apple and Google as the payment processors, not on CARV servers; required by commerce law	Per Apple/Google policy and applicable law (typically 5 years)
Server access and security logs	Kept briefly for abuse prevention and incident investigation	Up to 90 days

None of the retained items can be used to identify you or restore your account. They are deleted automatically when the retention period ends.

Before you delete

Deletion cannot be undone. Export your cards first from Settings → Export backup. Subscriptions are separate from your account: cancel them in App Store or Google Play subscription settings.
