Can I control how long a visitor's choice lasts, and can I force the Consent banner to reappear after a major policy change?
Yes. The published renewal configuration controls the consent duration in days and whether the banner should reappear after expiry. Existing visitors normally keep their stored choice until it expires, they change it, or a configuration change requires a new decision.
For an intentional one-off reset in the browser, window.OptinStack.renew() clears stored consent, resets categories to the current rule defaults, and makes the visitor eligible to see the banner again. Use renewal deliberately; repeatedly clearing valid choices creates a poor visitor experience.
