I can share some information about account subscriptions.
You'll have read-only access when opening your account once the subscription expires. Your data will be available for a year if you have paid subscription and 90 days for a free trial. I'll show you how to switch to annual billing.
Here's how:
1. Go to Settings ⚙ in the top right, and then Account and settings.
2. Click the Billing & Subscription tab.
3. Select Switch to monthly billing or Switch to annual billing.
