Privacy Policy

What we collect

Britain 2036 collects minimal data, all of it related to how people use the simulator. We do not require registration, login, or any personal information to use the tool.

Scenario data: When you view a simulation report, we log the policy lever positions you chose, the time horizon, and the philosophy preset (if any). This is the core data that lets us report on aggregate usage patterns — for example, the average migration target users set, or which presets are most popular.

Request metadata: We record a one-way cryptographic hash of your IP address (not the IP itself), your browser's user agent string, and the referring URL. The IP hash exists solely for rate limiting and basic abuse prevention — it cannot be reversed to recover your actual IP address.

Challenge submissions: If you submit a model challenge via the methodology page, we store the content you provide (issue type, description, edge reference) and optionally your email address if you choose to include one for follow-up. Your IP address is recorded alongside challenge submissions for rate limiting purposes.

What we don't collect

We do not use cookies, tracking pixels, or third-party analytics services (no Google Analytics, no Meta Pixel, no advertising trackers). We do not collect names, email addresses (unless you voluntarily provide one in a challenge submission), demographic information, device identifiers, or location data beyond what can be inferred from an IP hash. We do not fingerprint browsers.

Analytics

We use our own privacy-friendly, cookieless analytics — a self-hosted instance of Umami running on the same server as this site. It records aggregate page views, referring sites, approximate country, and broad device and browser type.

It does not set cookies, does not give you a persistent identifier, and does not follow you across other websites. Unique visits are estimated using a one-way hash that rotates daily and is never stored in raw form. The data stays on our own server and is never sent to any third-party analytics company — this is first-party measurement we run ourselves, not Google Analytics or any external tracker.

Leaderboard

If you choose to add your Britain to the public leaderboard, we store the policy settings you submitted, an optional display name (yours to choose, moderated for profanity), the scores the engine produces from your settings, your archetype and any badges earned, plus an anonymised IP-hash for rate-limiting. No cookies are set, and no personal data is stored. Submission is opt-in — the board only contains Britains people have actively asked to publish.

Display names that turn out to be abusive or otherwise out of bounds may be hidden or removed. You can request removal of any leaderboard entry by emailing us with the run id shown on the results page.

The board also contains a small number of illustrative model entries(prefixed “EXAMPLE —” and shown as diamond markers) based on UK political manifestos, historical governments, and well-known international models. These are anchors to populate the trade-off space — they're clearly labelled as not-real-submissions wherever they appear.

How we use the data

Scenario data is used in aggregate to understand how people interact with the simulator. We may publish aggregate statistics (e.g., “the average user sets a net migration target of 180k”) but will never publish or share individual scenario records in a way that could identify a specific user.

Challenge submissions are reviewed to improve the model. If a challenge leads to a model update, it may be cited in a public changelog. We will only contact you via email if you provided one and only regarding the specific challenge you submitted.

Data storage and retention

All data is stored on a private server in the United Kingdom. Scenario logs and challenge submissions are retained indefinitely for aggregate analysis purposes. You may request deletion of any challenge submission by contacting us with the reference ID provided at the time of submission.

Third parties

We do not sell your personal data, and we never share data that could identify you. We may share aggregated, anonymised, non-personal insights — for example, statistics on how people collectively use the simulator — including with clients of our professional version. These aggregates contain no personal data and cannot be traced back to an individual. The social sharing features (Twitter/X, LinkedIn, WhatsApp) use standard share URLs — no data is sent to those platforms until you actively click a share button, and at that point the interaction is governed by the respective platform's privacy policy.
