Notes

Events = customer-emitted track() / identify() calls. System lifecycle events (push.sent / email.delivered / etc.) + webhook deliveries are free across all tiers. See FAQ.
Critical Alerts require an Apple-issued entitlement (1-3 wk approval, news/marketing usually rejected) on top of the Growth+ plan.
BYOK for ai_action uses your own Ollama Cloud API key — no shared cap, you pay your own upstream. Available on every plan from Growth+.
Plan upgrades are immediate; downgrades take effect at the end of the current billing cycle.
