Privacy

On your device

The first time you draw a route, Overfly asks whether to keep your recent routes. Only if you say yes does it keep, in this browser’s local storage, the last twelve routes you entered and your display preferences: units, aircraft, cruise setting and map layers. Your answer itself is kept too, so the question is not asked again. None of it is sent anywhere. Clear it any time from the pages menu, or by clearing this site’s data in your browser; saying no later removes what was kept.

One thing is kept without asking: whether you last used Simple or Flight Ops mode, so the console opens the way you left it. It is a single word, says nothing about where you fly, and is never sent anywhere. Clearing this site’s data in your browser removes it.

Links and email

Share puts the whole chart in the link itself. Nothing is uploaded and Overfly keeps no record, but the address does go into your browser’s history, and anyone with the link can read the chart from it. Email opens a draft in your own mail app; Overfly never sees an address.

Analytics

Overfly uses Google Analytics to count visits and see which pages are used. On every page, Google’s tag records the page’s address, the page you came from, your browser and device type, and a rough location worked out from your IP address, and sets cookies to tell a returning visitor from a new one. A shared chart’s address carries its route, so a shared route’s codes are part of what it records. Overfly sees Google’s reports; it does not send your routes anywhere else.

Inside the map it also counts what is used: drawing a route, with its airport codes and number of legs (a coordinate you type is sent only as “COORD”, never the position), switching between Simple and Flight Ops, opening a printable brief, copying a link or opening an email, changing the wind model or the aircraft type, and following a link to Overfly’s Facebook, Instagram or X page. Custom aircraft names and anything else you type are not sent.

How Google uses this information: policies.google.com/technologies/partner-sites. To keep your visits out of Google Analytics on every site, use Google’s opt-out add-on at tools.google.com/dlpage/gaoptout.

Winds

Seasonal winds in Flight Ops mode are NOAA’s monthly averages, kept in Overfly’s own files and applied in your browser. Nothing about your route is sent anywhere to work them out.

Serving the site

Overfly’s pages, fonts, airport data and maps are all served from overfly.flights; no font, map or data service elsewhere is called from your browser. Like any website, the service that hosts it may keep standard request logs, such as the IP address, the page asked for and the time, to run and protect the site.

The links to Overfly’s Facebook, Instagram and X pages are plain links: nothing from those sites is loaded unless you follow one, and then their own privacy policies apply.

Contacting support

The support address is not written into the site; it is shown when you ask for it, to keep it away from programs that collect addresses for spam. Asking for it, or pressing Send on the suggestion form, first runs Cloudflare Turnstile, a check that you are a person rather than a program. It usually needs nothing from you. To make that check your browser loads a script from challenges.cloudflare.com, which looks at signals about the browser and the device (not your routes or anything you typed), and Cloudflare tells Overfly only whether it passed. Turnstile is not used to show ads or track you across sites. Nothing is loaded from Cloudflare until you ask. How Cloudflare handles this: cloudflare.com/turnstile-privacy-policy.

The email itself opens in your own mail app and is sent from there, by you; the suggestion form sends nothing to Overfly.

Ads

Ads from Google AdSense appear on the route and airport pages listed on the site, one to a page in a labelled box below the page’s own content; never on the map. To choose, show and measure ads and to prevent fraud, Google and its partners may use cookies and similar identifiers on your device and receive information such as your IP address and the page you are on. Overfly does not pass them anything about your routes.

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

Every page with an ad also loads Google’s ad-blocking message script, from fundingchoicesmessages.google.com. If an ad or script blocker stops Google’s scripts, it shows a notice across the foot of the page asking you to turn the blocker off and reload; the site itself works either way.

In the European Economic Area, the UK and Switzerland, Google asks for your consent before using cookies or showing personalised ads; without it, only non-personalised ads are shown. You can change that choice at any time from the link Google shows on the page.

How Google uses this information: policies.google.com/technologies/partner-sites. Turn off personalised ads from Google at adssettings.google.com, and from other participating companies at aboutads.info/choices.

Children

Overfly is not directed at children and does not knowingly collect anything from them.

Questions

Everything Overfly keeps about you is on your own device, where you can see and clear it. For anything else, email support (show the address). If this page changes, the date at the top changes with it.
