Questions
How the free allocation works.
What exactly is the free initial allocation?
A starting allowance to try Synderesis. It does not refill each month. See how much you have used under Usage in your Account.
What happens when it runs out?
You’ll be prompted to subscribe from your Account to keep using the workspace. Nothing is charged automatically. Your account, keys and history stay in place.
What does the subscription include?
Continued use of the workspace and API beyond the free allocation, with monthly credit from your payment after processor fees. Your first subscription month also includes €4 promotional credit. Pay €1 for your first subscription month, then €5/month. The offer is automatic for accounts with no previous paid subscription month; returning subscriptions and top-ups are not discounted. Monthly credit renews each period; top-up credit rolls over.
Can I cancel?
Yes. Go to Account → Subscription → Manage. You keep access until the end of your paid period, then return to the free plan.
