Privacy Policy
Last updated: 2026-07-27
postdoc.jp (operated by Japan Postdoc Job Center) respects your privacy. This page explains what data we collect, why, and your choices.
Data we collect
When you browse postdoc.jp, our hosting provider (Cloudflare) receives technical metadata such as your IP address, user-agent, referrer, and the pages requested. We also use Cloudflare Web Analytics, which measures page views and page performance without cookies and without storing any identifier on your device; it records the page URL, referrer, browser, operating system, device type, and country. Because it cannot identify or follow individual visitors, it runs regardless of consent. Google Analytics 4 is different: it loads only after you accept the consent banner. When you sign in via GitHub, the Cloudflare Workers auth service receives your GitHub user ID, login, display name, and avatar URL via the GitHub OAuth API. We do not store your GitHub email, repositories, or any private GitHub data.
Where data is stored
Authentication state is held in a short-lived JWT (HS256, 24-hour expiry) issued by our Cloudflare Worker and stored in your browser localStorage. The rating and audit data we publish on api.postdoc.jp is held on a Fly.io volume in the Tokyo (NRT) region.
Cookies & tracking
We do not place advertising cookies. Cloudflare Web Analytics uses no cookies and no device storage, so it falls outside the consent banner. Google Analytics is loaded only with your consent and uses a first-party cookie scoped to postdoc.jp. You can revoke consent at any time by clearing your browser storage for postdoc.jp. Until 2026-07-27, a tag inserted at our delivery layer could load Google Analytics before consent was given. That insertion has been removed. If you visited before that date, a cookie from it may remain in your browser; we now clear it automatically on your next visit, and you can also remove it by clearing your browser storage for postdoc.jp.
Your rights
Under the Japanese Act on the Protection of Personal Information (APPI) and applicable EU/UK data protection law, you may request access, correction, or deletion of your personal data. Contact contact@postdoc.jp.
Updates
We may update this policy as the project matures. Material changes will be flagged at the top of this page and announced on the registry.
