Sensitive in any
language.Secure in every one.
Contracts, clinical notes, court records, customer calls — whatever you translate, transcribe, voice, or caption moves through LANGUU encrypted end to end. Never sold. Never used to train models. Never kept longer than you decide.
Free translators pay their bills with your text. We don't.
Many free and consumer tools quietly retain what you paste, mine it, or feed it back into their models. LANGUU is built for work that can't leak — so the rules are simple.
Your content stays yours
We never add your text, audio, video, or captions to training datasets. Your material improves your results, not our models.
No third-party data trade
We don't sell, rent, or share your content with advertisers, data brokers, or partners. There is no second customer for your words.
Deleted on your schedule
Set retention to zero or a window you control. When it expires, source files and outputs are purged — not quietly archived.
How your content moves through LANGUU
Every job follows the same protected path — from the moment you upload to the moment it's gone. Each stage has its own controls.
Upload
TLS 1.3Text, documents, audio, and video reach us over an encrypted session. Nothing is written to disk in the clear, and uploads are scoped to your account from the first byte.
Encrypt
AES-256-GCMAt rest, everything is sealed with AES-256. Keys live in an HSM-backed service, are rotated on a schedule, and are never stored next to the data they protect.
Process
isolated runtimeTranslation, transcription, interpretation, speech, and captioning run in access-scoped, isolated environments. Your content is processed for your job only — and never folded into model training.
Human reviewoptional
locked workspaceTurn on human-in-the-loop review and vetted linguists work inside a controlled workspace — no downloads, no copy-out, confidentiality bound, every action logged. They see only what their task requires.
Deliver
authenticatedYou pull finished work over an authenticated session as DOCX, SRT, or audio. Share links are time-limited and revocable, so access stays in your hands.
Delete
purge, don't archiveWhen your retention window ends, source files, intermediate data, and outputs are permanently removed across systems and backups on a defined cycle.
Layered protection, end to end
No single control carries the load. Encryption, identity, infrastructure, and people each do their part.
Encryption everywhere
Your data is protected the whole way — in motion and at rest — with modern, audited cryptography.
- TLS 1.3 for all data in transit
- AES-256-GCM for data at rest
- HSM-backed key management & rotation
Identity & access
People reach only what they need, and every touch is recorded.
- SSO / SAML & enforced MFA
- Least-privilege, role-based access
- Full audit logging of access events
Hardened infrastructure
We build on providers held to the same bar we hold ourselves.
- Segmented networks & private services
- Continuous monitoring & alerting
- Regular third-party penetration tests
People & linguists
The humans in the loop are held to the same standard as the code.
- Background checks & confidentiality terms
- Reviewers work in a controlled workspace
- Annual security & privacy training
Independently checked, not self-declared
Our controls are tested by outside auditors and mapped to the frameworks regulated teams rely on. Reports are available on request.
Certified ISMS
Our information security management system is built and operated to the ISO/IEC 27001 standard — documented controls, formal risk assessments, and recurring surveillance audits by an accredited body.

Business Associate Agreements available, with safeguards for PHI across translation and transcription workflows.
CJIS
Controls aligned to the CJIS Security Policy for handling criminal-justice information and case content.
GDPR
Data Processing Agreement, EU data-residency options, and support for data-subject access and deletion requests.
No data sold
A standing commitment, written into our terms: your content is never sold or shared with third parties for their own use.
