Privacy Policy
Last updated: June 4, 2026
Introduction
Welcome to When Did They Join Bluesky? ("we," "our," or "us"). We respect your privacy and are committed to protecting your personal data. This privacy policy explains how we collect, use, and safeguard your information when you use our service.
Information We Collect
We collect minimal information necessary to provide our service:
- Bluesky Handles: The usernames you search for to look up join dates.
- Usage Data: Anonymous analytics about how our service is used (page views, features accessed).
- Technical Data: Standard server logs including IP addresses, browser type, and access times.
We do not collect passwords, private messages, or any sensitive personal information.
How We Use Your Information
We use the collected information to:
- Provide and maintain our service
- Look up publicly available Bluesky profile information
- Improve and optimize our service
- Monitor for technical issues and abuse
Third-Party Services
Our service interacts with the Bluesky API to retrieve publicly available profile information. We do not share your data with any other third parties for marketing or advertising purposes.
We use Google Fonts to display the typography on this site. When a page loads, your browser may request font files directly from Google's servers, which can result in Google receiving your IP address. This use is governed by Google's own Privacy Policy.
We may use analytics services to understand usage patterns. These services collect anonymized data and have their own privacy policies.
Cookies and Session Storage
We use cookies and server-side session storage to enhance your experience:
- Session Cookie: A cookie is set to identify your browser session. This cookie contains only a session identifier and no personal data.
- Session Data: We store the following information in your server-side session:
- Your most recently searched Bluesky handle
- The join date information retrieved for that handle
This session data is stored on our servers, not in your browser. While you can delete cookies through your browser settings, this will only remove the session identifier cookie. The associated session data on our servers will expire automatically based on our session timeout settings.
Session data is used solely to improve your experience (e.g., displaying your last search) and is not shared with third parties.
Data Security
We implement appropriate security measures to protect your information. However, no method of transmission over the internet is 100% secure. We cannot guarantee absolute security but strive to use commercially acceptable means to protect your data.
Data Retention
We retain search queries and usage data only as long as necessary to provide our service and comply with legal obligations. Technical logs are typically retained for a limited period for security and debugging purposes.
Changes to This Policy
We may update this privacy policy from time to time. We will notify you of any changes by posting the new policy on this page and updating the "Last updated" date.
