| Subprocessor | Purpose |
|---|---|
| Runs the AI models behind all AI features except transcription, and image moderation. Models come from developers such as Anthropic, DeepSeek, Moonshot AI, MiniMax, Z.AI, OpenAI, xAI, Alibaba, Mistral AI, Meta, Google, and Amazon. The developers do not receive your data. | |
| Amazon Polly (AWS) | Text-to-speech for the AI interviewer voice |
| Optional booking for demos and meetings | |
| Bot checks on sign-up, password reset, forms such as contact and newsletter sign-up, and assessment invitations | |
| Optional: link your Discord account to get roles in the AlgoArena Discord server | |
| Firebase / Google Cloud | Sign-in, database, file storage, server functions, and push notifications |
| Runs the cloud computers (Machines) for assessment questions, classroom build assignments, and Learn labs that need a full computer, including the terminal and the Claude Code and Codex agents. Each Machine runs in the Fly.io region nearest you, which can be outside the United States. | |
| Optional sign-in and 'Push to GitHub' code export. We also keep a private repository in our own GitHub organization for each assessment question that runs on a Machine and for each hackathon team. A hackathon organizer can make team repositories public after the event. | |
| Hermes (tryhermes.dev) | Lifecycle and re-engagement email |
| Product analytics and session recordings, only when Analytics is on. Never on assessment candidates' or classroom students' pages. |
