Data Security & Retention Policy

Unlike traditional commercial plagiarism software that permanently stores your essays in their private database (risking future false-positive flags on your own work), ToolSphare never retains, shares, or indexes submitted content.

Zero Server Storage: Your text is processed in transient memory and wiped immediately upon report generation.
No Indexing: Your unpublished manuscripts and research remain 100% proprietary and will never be indexed into public comparison banks.
GDPR & Academic Compliance: Fully compliant with academic student privacy rights and corporate non-disclosure agreements.

How Plagiarism & Similarity Detection Operates

N-Gram Shingling & Parsing: Text is stripped of punctuation and segmented into overlapping 5-word to 8-word shingles to detect exact matches and structural paraphrasing.
Database Verification: Passages are checked against open web indexes, open-access scholarly repositories, and Wikipedia citations.
Quotation Separation: Properly quoted text (enclosed in quotation marks or blockquotes) is isolated and marked in green, ensuring it does not falsely inflate the unoriginality score.
Similarity Score vs. Plagiarism: A similarity percentage indicates overlap with existing literature. Academic citations and common terminology are clearly distinguished from uncited duplication.
