Privacy Policy

Information we collect

CycleCalcs does not require an account and does not ask you for personal information. The calculators run entirely in your browser, so the words, names and numbers you type are processed on your device and are not transmitted to or stored on our servers.

Location and place search

Several tools on this site can use your location to show what is in the sky from where you are. This includes the Planet Parade Tracker, the Sky & Tonight tools such as Today in the Sky, the Moon Phase Calendar, the Eclipse & Saros Explorer and the Sunrise & Sunset page, and the individual object pages for the Moon, the Sun and the planets, which show each one's position for tonight from your location. The astronomy itself is always worked out on your own device, and so is everything to do with your location:

• Use my location. If you click this and allow it in your browser, your coordinates are used on your device to work out what is visible. To label that spot with a city name, your browser searches a list of places that is served with the page like any other file. Your coordinates are not sent anywhere.
• Place search. If you type a city or place into a search box, your browser matches what you type against that same list of places. The text you type is not sent anywhere.

Neither feature contacts a third party, so no outside service learns your location, sees what you type, or is given your device's IP address by us. The place list comes from GeoNames and is downloaded once, in full, the same way for every visitor, so what your browser requests reveals nothing about where you are. A location you choose is remembered only in your own browser, on your device, so a tool can restore it on your next visit; it is never sent to or kept on our servers, and clearing your browser data removes it.

Cookies and advertising

We intend to support this free site with advertising. When advertising is enabled, third-party vendors, including Google and Microsoft, may use cookies or similar technologies 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/or other sites on the Internet.
• You can opt out of personalized advertising by visiting Google Ads Settings.
• You can opt out of some third-party vendors' use of cookies for personalized advertising at aboutads.info/choices.
• For more on how Google uses data from sites that use its services, see Google's Privacy & Terms.
• Microsoft, including its pubCenter advertising platform, and its partners may similarly use cookies and your device information to serve and measure ads. You can manage Microsoft's advertising choices in your Microsoft ad settings, and read more in the Microsoft Privacy Statement.

Advertising and analytics vendors may collect information such as your IP address, device and browser type, and interactions with ads, in accordance with their own privacy policies. We do not control these third-party cookies.

Affiliate links

Some pages include links to products on Amazon. As an Amazon Associate, CycleCalcs earns from qualifying purchases. If you buy through one of these links, we may earn a small commission at no extra cost to you. These are ordinary text links; we do not collect any extra information about you when you use them, and any data Amazon collects after you arrive on its site is governed by Amazon's own privacy policy. Our picks are chosen on merit, not on commission. See our gear page for the full disclosure.

Analytics

We use Google Analytics 4 in a cookieless mode to see which pages are visited and how the site is used. It is configured not to store cookies on your device (its client_storage setting is none), so it does not keep a persistent identifier or track you across sessions or other sites. Google may process technical data such as your IP address (used briefly for approximate location, then discarded) and your browser and device type, in line with Google's privacy policy. We use this only in aggregate to improve the site, and we do not sell personal information.

Children's privacy

This site is intended for a general audience and is not directed to children under 13. We do not knowingly collect personal information from children.

Your choices

You can block or delete cookies through your browser settings and use the opt-out links above. Disabling cookies will not affect the calculators, which work without them.

Changes to this policy

We may update this Privacy Policy from time to time. Changes take effect when posted on this page, and the "last updated" date above will be revised.
