MapTiler

Overview

MapTiler is a mapping platform that provides customizable, OpenStreetMap-based map tiles for embedding interactive maps on websites and applications. Unlike Google Maps, MapTiler uses open data sources and offers self-hosting options, giving developers more control over map styling and data usage. The platform provides vector and raster tile sets, geocoding, and routing APIs that power embedded map interfaces.

What This Script Does

MapTiler's SDK (loaded from cdn.maptiler.com or bundled via npm as @maptiler/sdk) performs the following:

• Renders interactive map interfaces using WebGL for vector tile rendering or standard image tiles for raster maps
• Loads map tile assets from MapTiler's CDN (api.maptiler.com) using the site's API key for authentication
• Handles user interactions including pan, zoom, rotation, and click events on the map surface
• May use localStorage to cache tile data, reducing redundant network requests on subsequent page loads
• Stores map state (zoom level, center coordinates, bearing) in localStorage or URL parameters to preserve the view across page navigations
• Makes network requests to MapTiler's tile servers for each visible map tile at the current zoom level and viewport
• May request the user's geolocation via the browser's Geolocation API if a "locate me" feature is implemented
• Supports geocoding (address search) and routing (directions) through additional API calls to api.maptiler.com

The primary network traffic consists of tile requests to MapTiler's CDN. API key usage is tracked by MapTiler for billing purposes, but this tracking is server-side and tied to the API key, not to individual visitors.

Consent & Compliance

MapTiler serves a functional purpose: displaying interactive maps that are part of the website's content or service. The localStorage usage for tile caching and map state preservation supports the functional operation of the map component. Under GDPR and the ePrivacy Directive, storage that is strictly necessary for a service explicitly requested by the user (viewing a map) can qualify for the "strictly necessary" exemption.

If the Geolocation API is used, separate browser-level permission is required, which provides its own consent mechanism.

Under CCPA, MapTiler's tile requests do not typically constitute collection of personal information, as the requests are authenticated by API key rather than individual user identifiers. Map interaction data stays client-side.

The consent category for MapTiler is functional.

Should You Block This Without Consent?

No.

MapTiler provides functional map content that is part of the website's intended service. The localStorage usage for caching and state persistence serves the map's operation rather than visitor tracking. Blocking MapTiler would remove map functionality that visitors expect to interact with. No marketing or analytics tracking is performed by the base MapTiler SDK.
