Hosting and ordinary requests
Vercel hosts the site and therefore processes ordinary request information needed to deliver and secure it, including the requested URL, IP address, browser and device headers, timestamps, and server logs. The application also includes Vercel Web Analytics and Speed Insights, which receive page-view and performance measurements.
PostHog analytics and session replay
In production, the site initializes PostHog through the first-party /ingest proxy when a PostHog key is configured. It records page views and page leaves, anonymous device and session identifiers, interaction analytics and heatmaps, web-vital and network-timing measurements, and session replay when enabled by the PostHog project. The deployed project configuration also enables replay-related console recording.
The code configures PostHog person profiles as identified-only and does not call an identify method. Proxying analytics through optimism.fun does not make PostHog the operator: analytics events and replay data are still processed by PostHog in its US service. Avoid entering secrets or sensitive personal information anywhere on the site.
Cookies and browser storage
The initial HTML response does not set an application cookie. The problem table saves a visitor’s visible-column preference in localStorage, and PostHog stores anonymous device, session, and configuration state in browser storage. Clearing site data removes those local values, although provider-side records may remain under the retention settings of the relevant service account.
Newsletter subscriptions and feedback
A newsletter subscription sends the submitted email address to Resend and adds it to the configured optimism.fun audience. If Resend is unavailable or unconfigured, the fallback writes the email address, signup source, and timestamp to Vercel runtime logs instead. Every newsletter is intended to include Resend’s unsubscribe mechanism.
The feedback dialog submits a rating, message, optional reply email, current page, and browser user-agent information to the application. When Resend is configured, the handler emails the rating, message, page, and optional address to the operator; otherwise it writes the handled feedback fields to Vercel runtime logs.
Optional founder-fit interview
The founder-fit interview sends the full conversation with each request to the configured model path. Hosted deployments use Vercel AI Gateway and its configured model provider, currently MiniMax in this code; a directly configured environment can use Anthropic instead. The application treats the interview as stateless and does not write those answers to its Neon research database.
Research data, external assets, and links
Server-side research jobs query public data services and can store indicator records, sourced candidates, trends, and administrative publishing records in Neon Postgres. Those jobs are for the published research rather than visitor form submissions. The homepage also requests its globe texture from unpkg.com, which receives normal network request metadata, and outbound links are governed by the destination’s own policies.
Sharing, retention, and choices
Personal or device data is shared only along the service paths described above: Vercel for hosting and measurements, PostHog for analytics and replay, Resend for subscriptions and feedback delivery, and the AI gateway and model provider for an interview a visitor chooses to use. The repository does not define one fixed retention period for those providers, so their configured account settings control retention.
Visitors can browse without submitting the newsletter, feedback, or interview forms; clear local site data to remove browser-stored preferences and identifiers; use the unsubscribe link in an email; or use the contact page for an access or deletion request. A request may require enough detail to locate the relevant provider-side record.
