We do not require an account or collect personal information to use Calgary Weather Map. Your temperature-unit preference (°C/°F) is stored only in your browser's localStorage and never leaves your device.
The "find my location" feature uses your browser's Geolocation API, with your explicit permission each time. Your coordinates are sent only to our server to look up weather for that point, and are not stored or logged against you.
When the map first loads, we also use an approximate, city-level location derived from your IP address by our CDN (Cloudflare)to highlight the Calgary district you appear to be in. This uses information Cloudflare already sees as it delivers the site — no data is sent to any third party, and nothing is stored. If your IP isn't within our coverage area, nothing is highlighted.
Weather data is sourced from Open-Meteo. Map tiles are served by OpenStreetMap contributors. See our Cookie Policy for details on cookies and local storage.
Any changes to this policy will be reflected on this page with an updated date.
