Each rule card shows its schedule as a small chip - that's how often Clicc asks Google for fresh data to re-check the rule.
The cadences
Every 5 minutes - the security watchers (new users, manager links, pending invites) and critical setting changes. These are the "someone is in my account" rules, so they run near-continuously.
Every 15 minutes - disapprovals and campaigns that stop serving.
Every 30 minutes - account went dark and runaway spend.
Hourly - conversion tracking health.
Daily at 6am - all eight Operational performance rules, checked against complete daily data.
Weekly, Monday 6am - the four Hygiene rules.
Good to know. Daily rules judge complete days and weekly rules judge complete weeks, so a half-finished today or a half-finished week never creates a fake drop.
