Technology & Security
How it is built and how it protects.
Public: a general overview of operation in the EU, data protection and the handling of AI. The in-depth details — architecture, data flows, individual protective measures — are visible only to signed-in administration and operators.

- Technology & Security详细How the platform is builtA web application that runs in the browser, with a relational database in Frankfurt and data centres in the EU — multi-tenant, multilingual, secured by thousands of automated tests.学生教师行政运营方
- Technology & Security详细Operation and data in the EUDatabase, files and server functions are in Frankfurt — as a hard rule in the code that an automated test checks on every change. Individual services such as speech output work in the USA; they are named.学生教师行政运营方
- Technology & Security详细AI on the platform — what it may and may not doAI writes suggestions, presents courses and answers questions — labelled, bound to sources and with fixed limits: it does not assess exam behaviour and decides nothing that a person must decide.学生教师行政运营方
- Technology & Security详细Architecture and hostingThe building blocks of the installation, their locations and how a request runs through them.行政运营方
- Technology & Security详细Database and tenant separationEvery table carries the organisation; the database itself decides who sees which row.行政运营方
- Technology & Security详细AI models and speech servicesWhich kind of service is used for what, where it works and what it gets to see — described by function, not by provider.行政运营方
- Technology & Security详细Sign-in, second factor and encryptionHow accounts, sessions and secrets are protected.行政运营方
- Technology & Security详细Protection against injected code and abuseContent security policy with a nonce per request, origin check, limits per network address and bot defence.运营方
- Technology & Security详细AI guardrailsImmutable rules before every model call, a deterministic check of every input and a check of every output — with a log.行政运营方
- Technology & Security详细Cost recording and usage limitsEvery call to an external service goes through one single recording point; limits apply in stages.运营方
- Technology & Security详细Background runsScheduled runs for reminders, cost warnings, reports, fact checks, deletion calendar, learning data and pre-production.运营方
- Technology & Security详细Tests and guardsAround 3,400 automated tests, including 142 guards that permanently prevent mistakes once made — each with a counter-check.运营方
- Technology & Security详细Data flowsWhat flows where when a question is asked in a course, when a course is built and when an exam is taken.行政运营方
- Technology & Security详细Load test for many concurrent usersA tool that measures how many concurrent users the installation can handle — with a request cap, abort under overload and a report as a file. Measured up to 150 reading users; the large stages run as a project service against a preview environment.运营方
