Overview:
Unity Analytics applies Fair Usage limits to keep the service reliable and predictable at scale. These limits scale with your Monthly Active Users (MAU) and cover two things:
- Custom events per MAU per month (500 custom events per MAU)
- SQL Data Explorer query time per MAU per month (0.05 seconds per MAU)
If your project is under the Free Tier (fewer than 50,000 MAU), you might still see “overage” banners or usage percentages in the dashboard as you query data, but those indicators are informational. Fair Usage limits are only enforced for billing purposes once your project exceeds the Free Tier threshold. Even above the Free Tier, exceeding Fair Usage does not automatically bill you; if you are a paying Analytics customer, Unity may contact you to reduce usage or agree special terms. The intent is to prevent abuse and protect service quality, not to penalize normal development or testing.
Symptoms:
You may see one or more of the following in the Analytics dashboard:
- SQL usage warnings or “overage” percentages even on small datasets or during beta tests.
- Custom Events usage warnings, often tied to spikes in event volume or high invalid-event rates.
- Concern about charges when experimenting below 50,000 MAU.
Cause:
- The dashboard displays your usage against MAU-based Fair Usage allocations for both SQL time and Custom Events.
- For Custom Events, the limit is MAU × 500 per month; both valid and invalid events count. High invalid-event rates (schema mismatches, undeclared parameters, wrong types) can inflate usage quickly.
- For SQL, the limit is MAU × 0.05 seconds per month; time is measured on the server, not by result size.
- Under 50,000 MAU (Free Tier), warnings are informational. Fair Usage is enforced for billing purposes only above the Free Tier and after outreach.
Resolution:
- If your project is under 50,000 MAU:
- You will not be billed for exceeding the Fair Usage indicators. Continue testing safely.
- If your project is at or above 50,000 MAU:
- Your monthly allowances scale with MAU (see examples below).
- If sustained usage materially exceeds your allowance, Unity may contact you to reduce usage or agree special terms.
- Optimize your Custom Events volume and SQL query efficiency to stay within allocation.
