Privacy policy

Iyundhu has no sign-up and no user accounts. We do not ask for your name, email address, or payment details, and there is no database of visitors.

Your chosen place and your field log are written to this browser's local storage. They stay in this browser. They are not transmitted to us and we cannot read them.

If you tap “use my location”, your browser hands the page a latitude and longitude. That coordinate is used in the page to compute rise times, twilight, and ISS passes, and is kept in local storage so you do not have to re-enter it. It is not sent to our server.

Clearing your browser's site data for this domain erases all of it. There is nothing to request or delete on our side, because we hold nothing.

Sun, moon, planet, and star positions are computed in your browser from published algorithms — no request leaves the page to produce them.

The ISS tracker calls this site's own endpoint, which reads public orbital telemetry from a third-party satellite API. Your location is never attached to that request.

Page fonts are served by Google Fonts, which receives your IP address in order to deliver the font files, as it does for any site using that service.

Our web host records standard request logs — IP address, user agent, requested URL, and timestamp — for security, abuse prevention, and uptime. These are ordinary server logs, retained for a limited period and not combined into visitor profiles or sold.

This site carries third-party advertising, including Google AdSense, to pay for hosting.

Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and other sites on the internet.

You may opt out of personalised advertising by visiting Google Ads Settings. You can opt out of a third-party vendor's use of cookies for personalised advertising at aboutads.info/choices. How Google uses data from sites that use its services is described at policies.google.com/technologies/partner-sites.

Visitors in the European Economic Area, the United Kingdom, and Switzerland are shown a consent message before personalised advertising cookies are set, and can change that choice at any time from the same message.

Some links on the kit page are affiliate links, including Amazon Associates. If you buy through one, the retailer may pay us a small commission at no extra cost to you, and will know the visit came from this site. Recommendations are not sold — nobody pays to appear on that page.

This site is not directed at children under 13 and we do not knowingly collect any information from them.

Because we store nothing that identifies you, there is no personal data for us to export or erase. For advertising data held by Google, use the Google links above. If you are in the EEA, UK, or California and believe we hold something about you, write to us and we will answer.

If what we collect changes, this page is updated and the date above changes with it.
