These Terms of Service (“Terms”) constitute a legally binding agreement between you (“User”, “you”, or “your”) and cileria GmbH, a company incorporated under the laws of the Federal Republic of Germany (“cileria”, “we”, “us”, or “our”), governing your access to and use of the Node Architect SaaS platform (the “Platform”) and all related services, websites, and documentation (collectively, the “Services”).

BY CREATING AN ACCOUNT OR OTHERWISE USING THE SERVICES, YOU AGREE TO BE BOUND BY THESE TERMS. IF YOU DO NOT AGREE, DO NOT USE THE SERVICES.

3. The Services

3.1 Description

Node Architect is an AI-powered tool that analyzes software project architectures and generates interactive dependency graphs. The Services are delivered entirely through the Platform — a web-based application providing account management, an interactive analysis workspace, usage analytics, and billing. Analysis requests are processed by our backend infrastructure; credit usage is tracked and deducted from your account balance.

3.2 AI-Generated Output

Analysis results, architecture graphs, node summaries, and edge analyses are generated by artificial intelligence and are provided on an “AS IS” basis. You acknowledge that: (a) AI-generated output may be inaccurate, incomplete, or misleading. (b) You are solely responsible for reviewing, validating, and deciding whether to rely on any AI-generated output. (c) cileria does not warrant the correctness, reliability, or fitness of AI-generated output for any particular purpose.

4. Account Registration and Security

• You may register using email and password or Google OAuth2. Email registrations require email verification before the account becomes active.
• Each individual may maintain only one active account. We reserve the right to merge or terminate duplicate accounts.
• You are liable for all credit usage incurred through your account, regardless of whether such usage was authorized by you.
• We may suspend or terminate your account immediately and without prior notice if we reasonably believe you are violating these Terms, engaging in fraudulent activity, or posing a security risk to the Services.
