CivAtlas / Privacy

Privacy and your reading preferences.

This page describes the current English Web edition. It does not describe the separate WeChat mini-program.

Reading preferences stay in this browser

The interactive atlas uses browser local storage to remember the selected story, era and region, playback speed, timeline mode, active panel and reading scroll positions. Language preferences may also remain from earlier visits. The current Web edition offers English.

This information is used locally to restore your reading state. The application does not upload it to a user account or provide cross-device synchronization. There is no sign-in or account registration.

You can remove these preferences using your browser's site-data controls for atlas.2358.ai. Clearing site data resets your reading position and choices. Blocking local storage still allows reading, but preferences may not survive a later visit.

Loading the site sends web requests

Pages, history data, scripts, fonts and illustrations are served as site resources. As with other websites, the hosting infrastructure receives the information needed to deliver a request, such as an IP address, requested URL and browser request headers. The Web edition is hosted on Vercel; its infrastructure may process request and security logs.

The application does not use advertising cookies or a third-party advertising script. It does not request your device location, microphone or camera. Browser caching may retain site resources to make later visits faster.

Basic visit statistics and your choice

CivAtlas is configured to use Vercel Web Analytics for aggregate visit reports on atlas.2358.ai, subject to the service being enabled and your privacy choices. Reports can include page views, referring-page information, device and browser information, and approximate countries, regions or cities inferred from requests. Vercel uses a visitor-identification hash derived from incoming requests, discarded after 24 hours, rather than third-party analytics cookies. This does not mean every web request is anonymous; hosting and security processing still apply. Referring-page information depends on the browser and the referring site's policy. Analytics does not request precise device location.

Before sending a page view, this site removes query parameters and fragments from the current page URL, rejects unrecognized page paths, and suppresses repeated views of the same path within one document. It does not send search terms, local reading progress, map selections or playback actions to analytics. Local development and preview domains do not collect these visits.

Your privacy preferences take priority. Do Not Track or Global Privacy Control prevents analytics collection here, even if you select Enable. You can also disable it for this browser below. That choice is stored locally under civatlas.analytics.disabled.v1; clearing site data removes this choice along with reading preferences. This control does not delete previously collected reports or disable necessary hosting requests.

Feedback you choose to share

Opening feedback loads an embedded form from Tally. The service receives the connection information needed to deliver it, together with the public page, project and story context shown in the dialog. This site excludes unrelated URL queries, fragments, search terms and local reading records from that context.

When you submit, Tally processes the fields you choose to fill in, including any optional contact address, in the project’s form account. Contact details are optional. This site does not request a name or account, does not publish responses, and does not upload local reading preferences as part of feedback. The service may process its own technical or security information; this is not a promise that every request is anonymous.

The interactive atlas may show a small feedback invitation after you have spent two minutes in the foreground and actively opened three different stories. Closing the invitation or opening feedback saves a 30-day reminder preference in this browser. Only its expiry time is stored; the stories counted for the invitation stay in memory for this visit and are not sent to Tally or analytics.
