Tiered Retention Model

VisioLang uses a tiered retention approach to balance teacher visibility with student privacy:

• Student writing (full text) is retained for 14 days from the date of submission. During this window, teachers can review exactly what the student wrote alongside the AI feedback. After 14 days, the original text is automatically cleared.
• Feedback summaries and analytics (AI feedback, error patterns, verb/tense analysis, growth trends) are retained for up to 365 days by default. This allows teachers and students to track progress and identify persistent areas of difficulty across a full academic year.

Customizable Retention

District administrators can customize the data retention period to align with their district's data governance policies. Shorter or longer retention windows can be configured based on organizational requirements.

Data Deletion

• District administrators can request data deletion at any time by contacting VisioLang support.
• Deletion requests are processed promptly and cover all student submission data, feedback records, and associated analytics for the specified scope (class, teacher, or district-wide).
• Once deleted, data cannot be recovered.

Automated Purge Tooling

VisioLang provides automated purge tooling to support data lifecycle management:

14-Day Text Clearing

• Original student writing is automatically cleared (set to null) after 14 days.
• A short preview snippet (up to 160 characters) may be retained alongside analytics for context.
• This happens automatically during purge operations and does not require manual action.

Full Record Purge (at retention_days)

• AI-generated feedback summaries and structured analytics
• Per-submission scoring data, error tags, and strength tags
• Session and usage logs tied to individual submissions

What Is Preserved

• Teacher and administrator account records (active accounts)
• Class configuration and seat assignments
• Billing and subscription records
• Aggregated, non-identifiable usage statistics
