How MultiAI handles your data.

Operator

MultiAI (multiai.itlibra.com) is operated by JIT Corporation (JIT株式会社), Japan. Contact: https://jp-info-tech.com/

What we collect

Account: email address and a hashed password (bcrypt). API keys for third-party AI providers (OpenAI, Anthropic, Google) that you voluntarily register. Keys are encrypted at rest with AES-256-GCM. Only the last 4 characters are ever shown back to you; the plaintext is never retrievable via the UI. Chat content: your prompts and the model responses you generate, stored so you can review session history. You can delete individual sessions at any time. Usage metadata: per-message latency, input/output tokens, and estimated cost, used for the cost dashboard shown to you. Analytics: Google Analytics 4 (page views, referrer, approximate geography, device class). Ads: Google AdSense may set cookies to serve, personalise or measure ads.

How we use your data

To operate the service: authenticate you, deliver your prompt to the AI provider you selected, return and store the response, show you usage and cost metrics. To improve reliability: aggregate, non-identifying usage patterns. We do not sell your data. We do not use your chat content to train any model.

Third parties

When you send a prompt, it is transmitted to the AI provider you selected (OpenAI, Anthropic, or Google), using the API key you supplied, subject to that provider's own privacy policy and terms. Analytics: Google LLC (Google Analytics 4). Ads: Google LLC (AdSense). Hosting: Xserver VPS in Japan.

Cookies, analytics and ads (with opt-out)

EU / UK users: you have the rights of access, rectification, erasure, and objection under GDPR. US users: rights under CCPA where applicable.

Security

HTTPS everywhere. API keys encrypted with AES-256-GCM. Database isolated per service. Regular security patches. No system is perfectly secure; use strong unique passwords and consider rotating API keys periodically.

Data retention

Accounts and chat history are retained until you delete them or delete your account. Analytics data is retained according to Google Analytics defaults.
