Privacy

MapScores has no accounts, no ads and no cookies. The browser extension collects nothing at all. The website keeps simple, anonymous visit counts so we know which maps people use.

The browser extension

The MapScores extension shades neighbourhood grades onto the map search pages of realtor.ca and rew.ca.

• It collects nothing. No analytics, no tracking, no account, and no ID of any kind.
• It never reads listings. It doesn't read, store or send listing details, prices, addresses, photos or anything else from those sites. It uses only the map's position and zoom, plus the spot you tap on the map, so it knows which neighbourhoods to shade and which one to describe. Neither leaves your browser.
• It only downloads public MapScores data. Its only network requests go to mapscores.com for the same public neighbourhood shapes and statistics the website uses. Those requests carry no identifier and nothing from the page you're on, and they aren't counted in our visit stats.
• Settings stay on your device. Your lens, opacity and on/off choices are kept in Chrome's local extension storage (chrome.storage.local), and a one-hour copy of the downloaded MapScores data in the extension's own cache. Removing the extension deletes both.

We don't sell or share data, because the extension has none to sell or share. MapScores isn't affiliated with realtor.ca or rew.ca.

The website

No cookies, no third-party trackers. mapscores.com doesn't set cookies and doesn't load any advertising, analytics or social-media tracking scripts.

Visit stats

A small script of our own (/t.js) sends one note to our server when a page loads, and another when you use the map: switching a lens or persona, opening a neighbourhood, sharing, or searching. Each note holds:

• the page path and which action it was (for example, which lens);
• the other website that linked you here, if any (just its domain), and any campaign tags in the link;
• your screen width and whether you're on a phone, tablet or computer;
• a rough location (country, province and city) that our host, Cloudflare, works out from your connection;
• a visitor ID. It's a scrambled code (a one-way hash) made from your IP address, your browser's user-agent and today's date. It changes every day, so it can't follow you from one day to the next, and it can't be turned back into your IP address. Your IP address itself is never stored.

The notes are stored in our own database at Cloudflare and are used only to count visits and see which maps and lenses are useful. Searches are counted by type (address, street or town), not by what you typed.

Address search

As you type in the search box, the text goes to two address lookups: the BC Government's address geocoder (through our server) and Photon, a public geocoder run by Komoot that your browser contacts directly. We don't store what you typed. Our server may keep the lookup result for a day so the same search is faster next time, but it isn't linked to you.

“Request your city” form

If you ask us to add a city, we store the place you asked for, its map location, the search that led there and, only if you give it, your email address. We use the email only to tell you when that city's map is live, and we never share it.

Other services the pages load

Like most websites, pages load a few files from other services, which see your IP address as part of any normal web request: fonts from Google Fonts, the map library from unpkg, and map tiles from OpenFreeMap. None of them are used to track you on our behalf.

The map uses your browser's session storage for a moment when you jump between cities, to keep the animation smooth. It's deleted as soon as the next map opens.
