2. Introduction

At Fëanor's Code S.L., we are committed to protecting the privacy of our clients and users. This Privacy Policy describes how we collect, use, store, and protect your personal data in compliance with:

  • Regulation (EU) 2016/679 of the European Parliament and of the Council (General Data Protection Regulation - GDPR)
  • Spanish Organic Law 3/2018, of December 5, on Personal Data Protection and guarantee of digital rights (LOPD-GDD)
  • Law 34/2002, of July 11, on Information Society Services and Electronic Commerce (LSSI-CE)

3. Fundamental Principle: Privacy by Design

TENGWAR has been designed from its conception with privacy as a fundamental guiding principle:

Processing at Your Premises: Documents, queries, AI answers and search are processed on the servers installed at the client's premises. TENGWAR does not send your data to any cloud AI service.

External Connections, Only the Necessary Ones and Under Your Control: TENGWAR only communicates with the outside in three cases:

  1. When the administrator turns on an integration, for example Google or Microsoft email, a cloud ERP or BOE lookups, which exchanges with that service the data needed for the task.
  2. For access from mobile devices or outside the office, through a private network encrypted end to end.
  3. To check for and download software updates, without sending any data from your documents.

No Remote Access: The client keeps control over their data at all times. Fëanor's Code S.L. does not connect to the client's servers or access their documents. When the client needs support, they may choose to send us the system's technical logs; we use them only to diagnose the problem and prepare the fix, which the client installs as a software update.

4. Data We Process
