ConceptViz (“we,” “us,” or “our”) helps U.S. teachers generate classroom-ready diagrams. This Privacy Policy explains what information we collect, how we use it, and the choices you have. By using ConceptViz, you consent to the practices described below.
Effective Date: November 28, 2025
- Name and email address
- School, district, or subject focus (if provided)
- Authentication tokens for sign-in providers
- Subscription tier and payment status
- Billing address when required by regulation
- Transaction IDs from our payment processor (we never store full card numbers)
- Prompts and settings you submit to generate diagrams
- Generated images and metadata (subject tags, grade level) needed to deliver the Service
- Limited log data to troubleshoot errors, combat abuse, and improve quality
- Device type, browser, and operating system
- IP address and approximate region
- Session cookies or secure tokens to keep you logged in
We do not intentionally collect student names, grades, or other student PII. Do not include such data in prompts.
We process your data to:
- Provide, personalize, and operate the Service
- Track credit usage and enforce plan limits
- Respond to support requests and send service-related notices
- Detect fraud, abuse, or policy violations
- Comply with legal obligations (tax, accounting, law enforcement requests)
We may aggregate anonymized usage statistics to understand lesson trends and prioritize curriculum categories. Aggregated data cannot be traced back to a specific teacher.
We share information only with:
- Payment processors: To collect subscription fees and manage invoices
- Authentication providers: To log you in securely
- Infrastructure partners: To host the application, store images, and run AI workflows. These partners process prompts and images solely to deliver ConceptViz features and may not use them to train their own public models.
- Professional advisors or authorities: When required by law or to enforce our rights
We do not sell educator data or student-related information.
- Account data persists while your account remains active.
- Generated diagrams are stored for up to 90 days for paid accounts (shorter for free accounts) unless you delete them earlier.
- Billing records are retained for at least seven years to satisfy U.S. tax rules.
- Log data is typically retained for 30–90 days unless needed for security investigations.
You may email contact@conceptviz.app to request deletion of your account and associated content. Some records (like invoices) must remain for compliance purposes.
We use HTTPS, role-based access, encryption at rest for stored diagrams, and routine audits to safeguard your data. No system is perfectly secure, so please notify us immediately if you suspect unauthorized access.
- Access & Correction: View or update account details in your settings.
- Data Export: Request a copy of your diagrams and prompt history for a given time range.
- Deletion: Request account deletion by emailing contact@conceptviz.app.
- Marketing Opt-Out: Free and paid accounts may opt out of optional product emails via the unsubscribe link.
We use cookies to maintain sessions, remember preferences, and measure feature adoption. For details, see our Cookie Policy. You can control cookies via your browser settings, but essential cookies are required to use the dashboard.
ConceptViz is built for educators, not students. We do not knowingly collect data from individuals under 13. If you believe a student has provided personal data, contact us so we can delete it promptly.
We may update this Privacy Policy periodically. We will post the new version with an updated effective date. Continued use of ConceptViz after changes means you accept the revised policy.
For privacy questions or requests, email contact@conceptviz.app. We respond within two business days.
