Information about this website, the resources we share, and how its features work.
Using this website
Datumwell provides information about training data, articles, and research demos. Descriptions and examples help you evaluate fit; they do not guarantee suitability for a particular application. A tailored data engagement requires an agreed scope and usage conditions.
Dataset licensing and attribution
Each linked resource has its own license and usage conditions. This website does not replace those conditions. For EmbodiedTrace, consult the dataset card and its attribution notice before using or redistributing any assets.
EmbodiedTrace includes generated annotations marked as weak labels. They are not recorded human thoughts or verified object outcomes. Its derived action targets have not been separately executed on a robot.
Privacy and browser storage
Website analytics
PostHog and Google Analytics 4 run by default when you visit this website. There is no analytics consent popup or footer preference. These services measure visits, dataset download-link clicks, content engagement and confirmed inquiry submissions, using browser storage and first-party cookies to connect actions. Both respect Do Not Track and Global Privacy Control signals. Google advertising storage, advertising personalization and Google signals are disabled. We do not send contact emails, project names, requirements, search text or form contents as analytics events. Session replay and automatic interaction capture are disabled. URL query strings and fragments are removed from event URLs; only selected campaign labels are included. The separate aggregated Vercel statistics remain as described below.

Account features paused
Sign-in and personal subscriptions are temporarily unavailable. Community reading is public and does not load an authentication service. Previously created account records are not deleted by this interface change; contact allen@datumwell.io to request account-data deletion.
The site's theme and language preferences are stored in your browser's local storage when available. Language is also carried in internal page links so your selection can persist when storage is unavailable. You can remove stored preferences by clearing this site's browser storage.
We use Vercel Web Analytics to understand visits and page views through aggregated statistics, including referring sites, device and browser types, and approximate location. It does not use third-party cookies. We do not send the request form's email or requirements as analytics events. See Vercel Web Analytics privacy information for details.
The website is served by Vercel and requests fonts from Google Fonts. Visiting it involves requests to those services, which can receive connection information such as your IP address. Their policies describe their handling of that information: Vercel privacy policy and Google privacy policy.
External links and contact
The dataset and episode studio are hosted on Hugging Face. External sites apply their own terms and privacy policies. See also Resend’s privacy policy. When you submit a collaboration request, we store your contact email, requirements, optional Hugging Face username, project context and receipt in private Vercel Blob storage. Requests are scheduled for deletion after 180 days through daily maintenance. We use these details to review and respond to the request. A notification containing your request is sent through Resend to allen@datumwell.io; email copies may remain in the correspondence mailbox. Vercel processes the form API request. A one-way keyed hash of your connection IP and recent submission timestamps are used for abuse prevention; expired rate records are removed by daily maintenance. Request IDs and keyed hashes contain no contact details. Form contents are not sent as analytics events. You can ask allen@datumwell.io to access, correct or delete your request; applicable provider and correspondence retention may also apply. A saved-request confirmation means the database accepted the request, while notification delivery is retried separately through an hourly authenticated maintenance task. Vercel stores the request outside mainland China; our mainland-China server triggers maintenance without receiving form contents or storage credentials. Do not include secrets or sensitive personal information.
