Yes. Checkout goes through YooKassa, a licensed Russian payment provider. Card details are entered on their page, not on Patterna. We only receive payment status.
Searches and downloads are counted on the account, across all keys. They reset at midnight UTC. Creating or replacing a key does not reset today’s usage.
Free: 1 key. Starter: up to 3. Team: up to 5. All keys share the same daily limits.
