Privacy

Saved buildings

Your saved collection and light or dark theme preference are stored in your browser’s local storage. The collection is not sent to our server. Remove saved buildings on the collection page, clear site storage in your browser, or export your collection before switching devices.

Weekly email digest

Email registration is available only when the mailing service is connected. Registration requires your consent and email confirmation. The service stores your email address, subscription status and confirmation time to send the digest. Every edition includes an unsubscribe link. Unsubscribing disables future sends; an email address and delivery history can remain to honour that preference and prevent duplicate mail. RSS does not require an email address.

Delivery and security

When email is enabled, Cloudflare processes subscription requests and Resend delivers mail. Short-lived hashed request identifiers may be used to limit automated signups. Do not submit sensitive personal information through the signup form. Confirmation links expire; unsubscribe links must be kept private.

Site traffic

Cloudflare hosts this site and processes requests to deliver pages and protect the service. Traffic analytics may be enabled by the site operator. Official ticket and source links lead to other websites with their own privacy policies.

Your controls

Use the unsubscribe link in any digest email to stop delivery. Collection controls are available on Saved buildings. If email delivery is not enabled, no subscription address can be submitted through this site.

Watchlists and challenge scores

Your followed buildings, reviewed updates and quiz best scores are stored in this browser. They are not sent to a site account. Remove a followed building or clear scores using the relevant page controls; clearing site storage removes all local preferences. Watchlist exports contain your selected project IDs and reviewed event IDs. Shared skyline links contain the selected towers and poster title in the URL, so avoid private information in titles.
