Privacy Policy

Last updated: February 2026

What We Collect

LaunchSight is designed with privacy in mind. We collect the minimum data needed to provide satellite pass predictions and launch visibility calculations.

Location Data

When you use the prediction tools, your location (latitude/longitude) is used to compute satellite passes and launch visibility. This data is:

  • Stored locally in your browser (localStorage) so you don't have to re-enter it
  • Sent to weather APIs (Open-Meteo) to fetch current conditions — Open-Meteo does not track users
  • Never stored on our servers
  • Never shared with third parties for advertising or tracking

No Accounts

LaunchSight does not require user accounts. There is no login, no password, no personal information collection.

Analytics

We use privacy-first analytics to understand how people use the site (which pages are popular, how people find us). Our analytics:

  • Do not use cookies
  • Do not track individual users
  • Do not collect personal information
  • Comply with GDPR, CCPA, and PECR without requiring a cookie banner

Cookies

LaunchSight does not set any cookies. We use localStorage for your location preference and UI state only. If you subscribe to the email digest, Buttondown (our email provider) may set cookies on their domain for subscription management.

Advertising

Some pages display advertisements via Google AdSense. Google may use cookies and tracking technologies for ad personalization. You can opt out of personalized ads at Google Ad Settings.

Third-Party Services

The following third-party services receive data when you use LaunchSight:

  • CelesTrak — satellite orbital data (TLEs). No user data sent.
  • Open-Meteo — weather data. Receives your approximate location (latitude/longitude).
  • The Space Devs — launch schedule data. No user data sent.
  • Cloudflare — hosting and CDN. Standard web server logs.

Email Digest

If you subscribe to the weekly email digest, we store your email address and selected city with Buttondown, our email service provider. You can unsubscribe at any time via the link in every email. We never share your email with third parties.

Data Retention

We don't store your data on our servers. Your location is stored only in your browser's localStorage and can be cleared at any time by clearing your browser data or clicking "Change location" on any prediction page.
