The short version
AstroSight has no accounts and no sign-in. Your choices stay in your browser. To match prices and Buy links to where you live, the page looks up which country your IP address is in. The site shows ads from Google, which uses cookies if you agree to them.
What stays on your device
AstroSight saves your targets, settings, the country it detected and the latest price list in your browser’s local storage, so the page remembers them next time. This never leaves your device. Clearing your browser’s data for this site removes it.
Working out your country
When the page opens, it asks country.is (or GeoJS if that fails) which country your IP address belongs to. Like any website you visit, those services see your IP address. AstroSight gets back only a two-letter country code. It uses the code only to pick a store and currency, and keeps it for up to seven days.
If you tap “Use my precise location”, your browser asks your permission before sharing your coordinates. AstroSight matches them to a country on your device and never sends them anywhere.
You can always choose a store and currency yourself at the bottom of the page.
Advertising
AstroSight shows ads served by Google AdSense. Google and its partners use cookies to serve and measure ads and may personalise them. Visitors in the UK, the EEA and Switzerland are asked for consent first through Google’s consent message, and can change their choice at any time from the privacy link it adds to the page. How Google uses information from sites that use its services.
Affiliate links
Buy links go to Amazon, to camera and telescope makers, and to specialist astronomy retailers. Many are affiliate links: if you buy something, AstroSight may earn a commission at no extra cost to you. As an Amazon Associate, AstroSight earns from qualifying purchases. Once you follow a link, that retailer’s own privacy policy and cookies apply. Commissions never change what AstroSight recommends.
Analytics
AstroSight does not run any analytics.
