Last updated: July 18, 2026 · Product: CenterFlow (centerflowapp.com)

This policy describes how CenterFlow collects, uses, and shares information when you use our websites and apps, including Attendance Tracker, Student Roster, the Parent Portal, and related Class-Navi+ account sign-in.

Information we collect

• Account data: Email address and authentication data via Supabase when instructors sign up or sign in.
• Center operations data: Student roster details, attendance events, staff accounts, and family portal access codes that instructors or staff enter to run their learning center.
• Parent portal access: Family name and access code used only to authenticate parent sessions; codes are not stored in the browser beyond an optional signed session cookie/token.
• Billing data: Subscription status and Stripe customer identifiers when billing applies. Full payment card numbers are handled by Stripe, not stored on CenterFlow servers.

How we use information

• Provide attendance, roster, and parent portal features to your center
• Authenticate users and enforce access permissions
• Process payments and support billing inquiries when applicable
• Respond to support requests and improve reliability and security

Service providers

We use trusted processors including Supabase (authentication/database), Stripe (payments, when used), and Cloudflare (hosting). They process data according to their policies and our instructions.

Data retention

We retain account and center operations records as long as needed to provide the service and meet legal obligations. Instructors may request deletion of their account by contacting support.

Security

We use industry-standard practices including HTTPS and restricted API keys on the server. No method of transmission over the Internet is 100% secure.

Children

CenterFlow is intended for adult instructors, staff, and parents/guardians. Student information is entered by centers to operate their programs. The service is not directed to children under 13 as end users.
