Turnitin Similarity + AI writing report checks (document-in, report-out)

Requirements for every check:
- Both the Similarity report and the Turnitin AI writing report.
- Two separate, complete, unmodified original Turnitin PDFs (no screenshots, not just percentages).
- "No Repository" on every upload.
- You run the check yourself; no account sharing or login access.
- Genuine Turnitin only (no substitute tools, no edited reports).

Please reply with: price per check and volume tiers, limits (words, pages, format, language), turnaround and daily capacity, repository setting and data retention/deletion policy, account type and role, your basis for being permitted to offer paid checks, refund and re-check terms, and a redacted sample of both PDFs.
