AstroBuilder collects as little data as possible and does not sell or share your information with third parties for marketing purposes.

What we store

Build state. When you use the rig builder, your equipment selections are saved in a temporary server-side session and in your browser's local storage. This persists your build between page loads. It is not tied to any personal identity and expires when your session ends or you clear your browser data.

Analytics. This site uses Google Analytics to understand aggregate traffic — which pages are visited, roughly where visitors come from, and how people navigate the site. Google Analytics collects anonymized data including IP addresses (anonymized), browser type, and page views. No personally identifiable information is deliberately collected. You can opt out using the Google Analytics opt-out browser add-on.

Cookies

AstroBuilder sets only functional cookies required for session management (e.g. keeping your build state). Google Analytics sets its own cookies for traffic measurement. Affiliate networks may set cookies when you click product links — their cookie policies are governed by their own terms.

Third-party links

This site links to external retailers, manufacturer websites, and community resources. Once you leave AstroBuilder, we have no control over or responsibility for those sites' privacy practices.

Equipment data

Specifications, prices, and product information in the catalogue are sourced from publicly available manufacturer websites, vendor listings, and community resources. This data is not claimed as original intellectual property. Manufacturer names, product names, and brand assets are the property of their respective owners and are used here for identification purposes only.

Community content

Shared builds and community submissions remain the property of their creators. By submitting content to AstroBuilder, you grant the site a non-exclusive license to display it.

AstroBuilder is provided as-is, without warranty of any kind — express or implied. We do our best to keep information accurate and up to date, but we cannot guarantee it.

Prices and availability. Product prices and stock availability change frequently. Always verify pricing and availability directly with the retailer before making a purchase. AstroBuilder is not responsible for discrepancies between listed prices and actual prices at the time of purchase.

Compatibility. Compatibility suggestions on this site are based on best-effort community knowledge and general equipment specifications. They are informational only and should not be the sole basis for purchasing decisions. Always verify compatibility with the manufacturer or a knowledgeable source before buying.

No professional advice. Nothing on this site constitutes professional advice of any kind. Astrophotography equipment involves real money — do your own research and consult the community before committing to a purchase.

AstroBuilder participates in affiliate programs, including the Amazon Associates Program. This means that some product links on this site are affiliate links — if you click one and make a purchase, we may earn a small commission at no additional cost to you.

Affiliate commissions help offset the cost of running and maintaining this site. They do not influence which products are listed, how they are described, or what the compatibility logic recommends. The catalogue exists to be useful to the community — not to push specific products.

In compliance with FTC guidelines, all affiliate relationships are disclosed. If you'd prefer not to use affiliate links, you can search for any product directly on the retailer's site.
