Anonymize.Education is a zero-knowledge PII anonymization tool for schools that removes student personal data from documents before they are shared with vendors, researchers, or AI tools.

Price Comparison
Pricing scales with usage, not per-seat licensing. Teachers get a free tier for everyday use. Schools pay €29/month for about 1.75M characters; districts with higher volume get custom licensing. No minimum contract, no sales call - the rate card is public.
What "Zero-Knowledge" Actually Means for Student Data
Most privacy platforms process files on their own servers, so the vendor can technically read the data while scanning it. Anonymize.Education works differently: files are encrypted on the device before upload, using a zero-knowledge model built on Argon2id and HKDF key derivation. Even Anonymize.Education's own team cannot read student records in transit. As the comparison table shows, BigID's architecture is server-side - standard for enterprise discovery tools, but a different tradeoff than a tool built to anonymize student PII.
Detection: Hybrid Regex + NLP Across 267+ Entity Types
Anonymize.Education detects more than 267 entity types using a hybrid approach that combines regex pattern matching with NLP models (spaCy, Stanza, XLM-RoBERTa), across 48 languages. Entities can be handled five ways: Replace, Redact, Mask, Hash (SHA-256), or reversible AES-256-GCM Encrypt. Reversibility matters for schools - a district can anonymize a transcript for external sharing, then decrypt the original later if a court order or audit requires it.
EU Hosting and ISO 27001 Certification
Anonymize.Education's infrastructure runs exclusively on Hetzner servers in Falkenstein, Germany, an ISO 27001-certified facility. For schools with European students, EU-only hosting answers a common question from data protection reviews: where does the data physically live? The answer is always the same location, under German and EU law.
Frequently Asked Questions
What's the difference between Anonymize.Education and BigID?
BigID is a data discovery and classification platform: it scans an organization's infrastructure to find where personal data lives. Anonymize.Education is an anonymization tool: it removes or encrypts personal data from documents before they're shared with vendors, researchers, or AI systems. Many schools use the two for different jobs - discovery versus protection.
Does Anonymize.Education support FERPA compliance?
Anonymize.Education is built to support FERPA compliance by helping schools minimize personal data in a record before it's shared. The school itself remains responsible for its own FERPA obligations - no software product can be "FERPA certified," since that's a school responsibility, not a vendor certification.
How does zero-knowledge encryption protect student records?
Files are encrypted on the user's own device before upload, using Argon2id and HKDF for key derivation. Because the encryption happens locally, Anonymize.Education's servers never see the unencrypted student data. This is different from server-side platforms like BigID, where the vendor's infrastructure processes the raw data directly.
What does Anonymize.Education cost compared to BigID?
Anonymize.Education charges €29/month for the School plan (about 1.75 million characters) and custom volume licensing for districts, with a free tier for individual teachers. BigID is priced through an enterprise sales process at $100,000+ per year, which typically includes implementation costs.
Can Anonymize.Education replace a data discovery tool like BigID?
Not directly - they solve different problems. BigID discovers and classifies where sensitive data exists across an organization's systems. Anonymize.Education anonymizes specific documents and datasets before they leave the school. A district that needs both jobs done may use each tool for its respective strength.
Why Schools Switch
BigID excels at data discovery across enterprise infrastructure — scanning databases, cloud storage, and data lakes to show organizations where personal data exists. Anonymize.Education solves the next problem: protecting that data before it reaches AI tools, third-party vendors, or cross-border research partners. For K-12 and higher education institutions, purpose-built anonymization beats a general-purpose data catalog: 48 languages including CJK, Arabic, and Cyrillic scripts; offline Desktop App for air-gapped environments; and FERPA/COPPA compliance built in from day one.
48 Languages
Detect PII in any language. CJK, Arabic, Cyrillic, Hindi included.
Offline Mode
Desktop App works air-gapped. No cloud dependency.
Reversible Encryption
Decrypt when needed for audits or legal discovery.
Minutes, Not Months
Start protecting data immediately. No consultants needed.
