Xelmu Privacy Agreement

🌌Introduction

Xelmu is your personal astrophotography journal—crafted for amateur stargazers and night-sky photographers to capture, organize, and cherish their celestial adventures. This Privacy Agreement explains how we collect, use, and protect your information when you use our app. We value your privacy as much as you value your cosmic captures, so we’ve designed this policy to be transparent and aligned with the app’s core purpose: helping you build a private, immersive catalog of your astronomical journey.

📷Information We Collect

We collect information to enhance your Xelmu experience—all tied directly to the features you love:

• User-Provided Content: Photos imported from your camera roll, technical gear settings (camera, lens, telescope, ISO, shutter speed, aperture), environmental conditions (location, weather, moon phase, seeing quality), and any notes you add to your sessions.
• Optional Account Data: If you create an account (for cross-device sync), we collect your email address and a secure password (only for account recovery).
• Usage & Device Data: Device type, OS version, and app interaction data (e.g., how often you use the filterable gallery or side-by-side comparison tool) to improve performance and features.

🔭How We Use Your Information

Your data is used to power the magic of Xelmu:

• Organize your celestial sessions into a filterable gallery (sorted by Moon, Planets, Nebulae, Galaxies, Star Clusters).
• Enable side-by-side exposure comparisons to refine your astrophotography skills.
• Personalize your experience (e.g., remembering your preferred target filters or gear settings).
• Improve our app (e.g., adding new features like better location-based weather integration).
• Ensure security (protecting your data from unauthorized access or misuse).

🔒Information Sharing

Your cosmic catalog is private—we don’t share your personal data with third parties unless:

• You explicitly consent (e.g., sharing a session with a fellow stargazer via email).
• Required by law (in compliance with general legal obligations).
• With trusted service providers (e.g., cloud storage partners) who are bound by strict confidentiality agreements and only use data to support Xelmu’s functions.

⏳Data Retention

We keep your data as long as you use Xelmu. If you delete your account or uninstall the app (and opt to erase your data), we will remove all your sessions, photos, and settings within 30 days—except for data we need to retain for legal or security purposes.

⭐Your Rights

You have full control over your data:

• Access: View all your stored sessions and settings.
• Modify: Edit any session details (e.g., correct gear settings or update location info).
• Delete: Remove specific sessions or your entire account (and all associated data).
• Opt-Out: Choose not to provide non-essential data (e.g., location for weather—though this may limit some automatic features).

🛡️Security Measures

We protect your cosmic data with industry-standard security:

• End-to-end encryption for data in transit and at rest.
• Secure authentication (for account users) with encrypted passwords.
• Regular security audits to identify and fix vulnerabilities.

🔄Changes to This Agreement

We may update this policy to reflect new features or legal requirements. We’ll notify you via in-app messages or email (if you have an account). Your continued use of Xelmu after changes take effect means you accept the updated agreement.
