Privacy & data

The short version

You can explore the whole map without an account and without giving us anything. We measure traffic to understand how people find and use the site — in aggregate, not to identify you. We never store your IP address, we don’t run ads, and we don’t track you across other websites.

What we store

• If you make an account — your email, your @nickname, and the profile and privacy settings you choose. Friends and bookmarks are saved to your account so they follow you between devices. This lives in Supabase, protected by row-level security, and you can delete it by deleting your account.
• An anonymous browser marker — a random token stored in your browser (not linked to any identity) so the free AI guide can apply its “questions per day” limit. Clearing your browser storage removes it.
• AI questions — the questions asked of the guide are logged (with a one-way hashed marker, never a raw IP) so we can measure cost, improve answers, and stop abuse. Don’t type anything private into it.
• Analytics — anonymous, aggregate usage data (see below).

Analytics, specifically

We use two privacy-respecting analytics tools: Vercel Web Analytics and Google Analytics 4. They tell us things like how many people visit, which countries and devices they use, where they arrived from (the referring site or search engine), which pages and objects they open, and roughly how long they stay. It’s about the audience in aggregate — not about following a named person.

To keep it honest, Google Analytics here is configured to:

• never store your IP address — Google truncates it and we ask for IP anonymisation on top;
• run no advertising features — no Google Signals, no ad-personalisation, no cross-site or cross-device ad tracking;
• honour Do Not Track and Global Privacy Control — if your browser sends either signal, clAIp loads no analytics for you at all: no script, no cookie, nothing.

Analytics that aren’t suppressed by that signal set a small first-party cookie so a visit can be counted as one session rather than many. You can opt out at any time by turning on Do Not Track, using Google’s opt-out add-on, or blocking analytics with your browser or an extension — the map works exactly the same either way.

What we don’t do

• We don’t sell or share your data with data brokers or advertisers.
• We don’t store raw IP addresses anywhere.
• We don’t track you across other websites or build an ad profile.
• We don’t need an account for you to use the map, cards, search or time slider.

Your choices

Turn on Do Not Track / Global Privacy Control to switch analytics off entirely. Clear your browser storage to drop the anonymous marker. If you have an account, you can delete it — which removes your profile, friends and bookmarks.
