Your data refresh in Polar Analytics is dependent on the plan you're currently enjoying.

On the Analyze plan, we refresh data once daily at 1 AM in every account's time zone (however, if a connector is syncing data for multiple accounts and these accounts are in different time zones, then the connector will sync hourly instead).

On the Analyze and Enrich plan, we enable the intra-day refresh feature which will re-sync your data as often as possible, based on when the data is available from each sources' API. The intra-day refresh will ensure you have access to fresh data as frequently as each hour. Keep in mind that as we are dependent on the API of each data source, there can occasionally be refresh delays.

Keep in mind that there are a few connectors that have default time zone settings in Polar (or in the sources' API itself):
