Refunds

Given the nature of the Service, no refunds or prorated adjustments are provided as a rule. However, in the event of duplicate charges or erroneous charges caused by a technical fault on the provider side, the provider will, after confirming the facts, issue a refund to a reasonable extent.

Article 8 (Free Trial)

30-day free trial

Subscribing to a paid plan during that window reactivates the team at any time. If no subscription is made within 90 days of archival, the team becomes eligible for deletion. Upon a deletion request, the provider deletes the account and Content within 30 days of receipt.
