Privacy

What Dash Documentation Boilerplate stores about a visit, what it does not store, and where the numbers go — described from the code that does it.

This page describes what the code in this repository actually does. Each claim below corresponds to something readable in lib/analytics_tracker.py, and the test suite holds the two together.

What is stored about a visit

Every request that is not a bot or network machinery records one row:

• the time of the request;
• the path requested;
• a device type (desktop, mobile, tablet, bot);
• the User-Agent string your browser or client sent;
• a visitor key — a keyed one-way hash of your network address and

User-Agent, truncated, used to tell one visitor from another within the retention window;

• a location, if and only if the network edge in front of this site sent

one (see below).

Crawler rows additionally carry the vendor identity the classifier determined — which bot it was, and whether it verified.

What is NOT stored

• Your IP address. It is read from the request so the site can tell one

visitor from another and so the edge's country header can be matched to it, and then it is reduced to the visitor key and discarded. It is not written to disk. (An operator running their own copy of this template can set ANALYTICS_KEEP_CLIENT_IP=1 to keep it. This site does not.)

• Anything from a third-party lookup service. Earlier versions of this

template sent visitor addresses to a geolocation API. That code was removed — not disabled — in release 1.6.44. This app makes no outbound request about you.

• Cookies for analytics. The visitor key is computed per request from

what your client already sent. Nothing is stored in your browser to track you. Signing in sets a session cookie, which is what keeps you signed in.

Where location comes from

From the network edge, or not at all. Cloudflare sits in front of this site and adds headers describing where a request entered its network: CF-IPCountry always, and CF-IPCity, CF-Region, CF-IPLatitude and CF-IPLongitude when the zone is configured to send them. Whatever arrives is stored; whatever does not is simply absent. There is no lookup and no fallback to one.

You can see which of those headers this host is actually receiving — they are listed in the geo.headers_seen field of https://boilerplate.2plot.dev/healthz.

Network machinery is counted nowhere

The 2plot network's own traffic — health checks, deploy batteries, link audits — carries a marker in its User-Agent and is dropped before anything is recorded. It is not in these numbers, by design.

How long it is kept, and where it goes

Rows are pruned on a retention window and the file is capped in size. A daily summary — counts by day, by page, by country, by crawler vendor — is sent to the 2plot network hub. The summary carries no visitor keys, no addresses and no User-Agent strings: it is counts.

Signing in

Sign-in is handled by Clerk. What Clerk stores about an account is governed by Clerk's own privacy policy. This site keeps the identifier it needs to decide what you may see.
