ClassDojo versus Bloomz
Compare	ClassDojo	Bloomz
Verdict	Worth it	Depends
Best for	K-8 behavior tracking	K-12 districts consolidating multiple parent-comms apps
Who it's not for	Teachers who hate public behavior points	Districts already standardized on ParentSquare or brightwheel
Privacy	No known public vulnerabilities found in the sources reviewed.¹⁰	FERPA/COPPA compliant with a Student Privacy Pledge; not HIPAA; compromised user accounts and infostealer credentials reported.
Support quality	No support-quality evidence in sources reviewed	'Not dependable' complaints; login-issue threads
Public sentiment	Teachers and parents praise its simplicity and free price, but a vocal minority loathe the public points system and forced rollouts.^⁴	Teachers mostly praise ease of use and parent engagement, but a loud minority report unreliability, weak support, and account hacks.
Biggest gotcha	One reported incident: a student hacked a teacher's account and mass-awarded points. Anecdotal.	Account takeover occurred without clear 2FA; enable it school-wide at rollout.
