Cookie policy

viewmygpx uses Google Analytics 4 to measure anonymous traffic, which sets a small number of first-party cookies in your browser. Beyond that, the page sets nothing — no preference cookie, no login cookie, no tracking pixel under our domain. The viewer, editor, and converters all run client-side and the cookies have nothing to do with your GPX file content.

This page lists every cookie that may appear when you visit the site — first-party (Google Analytics) and third-party (map tile providers, CDN) — and explains how to control each.

What a cookie is

A cookie is a small piece of text that a website asks your browser to store and send back on subsequent requests. Sites use cookies to remember preferences, keep you logged in, or track you across pages. Other small storage mechanisms (localStorage, sessionStorage, IndexedDB) work similarly; for the purposes of this policy we treat them all together.

Cookies viewmygpx sets (first-party)

Google Analytics 4 sets two first-party cookies for anonymous traffic measurement:

  • _ga — assigns a random visitor ID so Google Analytics can count returning visitors as one person rather than several. Lifespan: 2 years from the most recent visit. Does not contain your name, email, or any personally identifying data — just a random number.
  • _ga_JPMSXJ592Y — Google Analytics 4 session cookie, used to maintain session state. The suffix is the property's measurement ID. Lifespan: 2 years.

Beyond those two analytics cookies, the site sets no other first-party cookies. There is no "remember me," no preference cookie, no fingerprinting script, no tracking pixel. The GPX file content never reaches Google Analytics — analytics records page URLs and visit metadata, not file data, which never leaves your browser.

Third-party cookies that may appear

A handful of third parties are involved in delivering the site. They operate under their own policies; if they set cookies, those cookies live under their domains, not ours.

  • Google Analytics infrastructure. Beyond the first-party _ga cookies above, Google Analytics 4 may set additional third-party cookies under the googletagmanager.com and google-analytics.com domains. Google's own privacy policy at policies.google.com/privacy covers what they do with the data. Analytics-data retention on our property is set to the GA4 default (2 months for user-level data, 14 months for event-level data).
  • Map tile providers. When the viewer renders a route on a map, your browser fetches map tile images from the configured provider — Stadia Maps when configured, falling back to OpenStreetMap tiles, plus Esri World Imagery for satellite view. These providers may set caching cookies for their CDNs. The privacy policies of the providers govern their use of cookies and your data.
  • Hosting and CDN. The site is served from a CDN edge. The CDN may set technical cookies to manage traffic distribution; these are not used to identify you across sites.
  • Future advertising. The long-term plan is to support the site through display advertising on guide pages — never on the viewer, editor, or converters. If and when an ad network is enabled, that network will set cookies that we will enumerate here, with links to the network's opt-out mechanisms.

How to control cookies in your browser

Every modern browser lets you block, allow, or delete cookies on a per-site basis. Blocking cookies for viewmygpx.com prevents Google Analytics from counting your visits but does not affect the viewer, editor, or converters — those run without cookies. To opt out of Google Analytics specifically, the official browser add-on at tools.google.com/dlpage/gaoptout disables GA4 across every site you visit.

For most users, the default settings of a modern browser already provide reasonable protection. If you use a private or incognito window, cookies are isolated from your normal browsing and discarded when the window closes — viewmygpx works fine in private windows because the tool itself does not need cookies.

Do Not Track and Global Privacy Control

Browsers can send a "Do Not Track" (DNT) header or a Global Privacy Control (GPC) signal. Google Analytics 4 honors GPC by default in regions where it is recognized as an opt-out signal (e.g. California under CCPA). We do not run any first-party tracking beyond the GA4 cookies above. For third-party services we depend on, the signals are passed along and honored at the discretion of those providers.

Updates to this policy

When we change something material — a new third-party service, an ad-network rollout that introduces cookies — we update this page in place. The change takes effect when the page is published.
