Encrypted storage
Documents are encrypted client-side before upload. The Vault stores ciphertext.
Private by design. Clear about the details.
Understand how your documents are stored, how AI requests are processed and what happens to your data. The details belong in the open.
From your document to your answer.
Processing within the EU
For an AI request, the required content is decrypted in memory and processed within the EU.
No model training
Your documents, prompts and responses are not used to train foundation models.
Hosted in the EU, processed in the EU
The Tero platform and its AI inference run on managed cloud infrastructure entirely within EU regions, under the relevant Data Processing Addenda. Every sub-processor — cloud, database, compute and AI inference — operates within the EU/EEA, and we give advance notice of any material change so you can object before it takes effect.
Our full, named sub-processor list is available under our GDPR Data Processing Agreement — request it any time at privacy@tero.legal.
Private AI endpoints on request
For organizations requiring complete inference isolation, Tero can route AI processing to private or on-premise LLM endpoints — your documents never touch shared AI cloud infrastructure.
Know what is kept, and for how long.
