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 Cloudflare Pages; 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.
Visit statistics
This Cloudflare Pages edition does not load Vercel Web Analytics or a replacement visit-analytics script. No page views, search terms, map selections, reading progress or playback actions are sent to a visit-analytics provider by the application.
A previous Vercel analytics preference may remain in this browser under civatlas.analytics.disabled.v1. It is not used to enable analytics on this edition. Hosting infrastructure still receives the information needed to deliver and protect web requests, as described above.
Links and advertising
History bibliographies display reference titles without external website links. Internal links open the atlas, reading pages or review notes.
No advertisements are currently enabled. If advertising is introduced, this notice must be updated to identify the provider, explain its cookies or data use, and provide the required consent or privacy choices before those services run. A future plan to use advertising does not mean it is active today.
Changes to this notice
This notice applies to the features described above. Revisit it when the site adds services that change how information is handled. For the site's content and editorial limitations, read About & methods.
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.
