Data processed in Germany (Hetzner). No US Cloud Act exposure. Guaranteed EU jurisdiction.

Reversible Encryption

AES-256-GCM encryption with your keys. Decrypt when needed for audits, court orders, or compliance.

Chrome Extension

Zero-Knowledge Security

When Azure AI Language Might Be Better

Azure AI Language excels in specific scenarios:

  • Already on Azure: Deep integration with Azure services and unified billing
  • Azure Functions/Logic Apps: Native triggers and connectors for automation
  • Azure Health Data Services: Combined with de-identification for PHI workflows
  • Microsoft 365 integration: Part of broader Microsoft Purview ecosystem

Frequently Asked Questions

Does anonym.legal require an Azure account?

No. anonym.legal is completely independent of Microsoft Azure. Use it via API, Desktop App, Chrome Extension, or Office Add-in without any Azure infrastructure or billing.

How does anonym.legal pricing compare to Azure AI Language?

anonym.legal offers transparent pricing from Free to €29/month. Azure AI Language uses pay-per-use billing based on text records processed, which can be unpredictable at scale. anonym.legal is typically more cost-effective for most use cases.

Can I migrate from Azure AI Language to anonym.legal?

Yes. Both use similar REST API patterns. The main changes are authentication (API key vs Azure credentials), endpoint URLs, and response format mapping. Most integrations can be migrated with minimal code changes.

Does anonym.legal support reversible encryption?

Yes. anonym.legal provides AES-256-GCM reversible encryption — you can decrypt when legally required for audits or court orders. Reversible encryption documentation was not found on Azure AI Language's product page.

Which has better entity coverage?

anonym.legal detects 285+ entity types with country-specific IDs (German Personalausweis, French INSEE, UK NIN, etc.). Azure AI Language doesn't publish specific entity counts, making comparison difficult.

Does anonym.legal offer zero-knowledge authentication?

Yes. anonym.legal uses zero-knowledge authentication with Argon2id and HKDF. Your password is processed on your device — only a mathematical proof is sent to the server, never the actual password.

Words from our team

We started this work after a lunch about cookies.

One friend kept getting odd ads on her phone.

We asked why a court file leaked through a draft.

We sketched the first build on a napkin that week.

By month three we had a tiny demo for a friend.

She used it on her first case the next day.
