Privacy policy
FlutterTrends is a static site. The only tracking it runs is Google Analytics 4, used to measure traffic patterns. This page explains what GA4 sees, what we don't do, and how to opt out.
What we collect
We use Google Analytics 4 (GA4), Google's traffic-measurement product, to understand which pages get visited and roughly where visitors come from. GA4 sets two first-party cookies in your browser (_ga and _ga_*) and reports anonymised events to Google's servers. Each event includes:
- The URL of the page you're on and the URL that referred you
- A truncated IP address (GA4 drops the last octet before the data is stored, per Google's IP-anonymisation policy)
- Your country and approximate region (derived from the truncated IP)
- Browser, operating system, and device-type strings from your User-Agent header
- A randomly generated client identifier stored in the
_gacookie, so repeat visits within ~2 years can be counted as one visitor
We do not enable Google Signals, Google Ads linking, or any cross-site personalisation features. We never send personal data (names, emails, account IDs) to GA4 — there are no accounts on FlutterTrends and no forms on the site, so there's nothing to send.
What we don't do
- No advertising tags. No Google Ads, no Facebook Pixel, no LinkedIn Insight, no remarketing or retargeting tags of any kind.
- No third-party JavaScript beyond the GA4 snippet (loaded from
googletagmanager.com). - No user accounts, no logins, no comments, no contact forms, no newsletter sign-ups.
- No selling or sharing of data with third parties beyond Google's standard GA4 processor relationship.
- No fingerprinting or tracking-pixel networks.
How to opt out
Several straightforward options:
- Install Google's official Analytics Opt-out Browser Add-on — disables GA4 across every site you visit.
- Use a content blocker (uBlock Origin, AdGuard, Brave's built-in shields, Safari's privacy controls) — all standard blocklists block
googletagmanager.com. - Browse in Firefox with Enhanced Tracking Protection set to "Strict", or in Safari with Intelligent Tracking Prevention — both block GA4 cookies by default.
- Block the cookies in your browser settings:
_gaand_ga_*on this domain.
If you opt out, the site works exactly the same — GA4 has zero impact on what you see or how pages render.
Server logs
The host (Hetzner) keeps standard nginx access logs containing IP addresses, request paths, response codes, and User-Agent strings, rotated per the host's standard log-retention policy. These are operational logs only, never joined with GA4 data, and never used for tracking individual visitors.
Data sources we fetch
During the daily build, FlutterTrends's server fetches package data from pub.dev and stargazer counts from github.com. These are server-to-server calls — your browser is not involved and no information about you flows to either source from this site.
Your rights (GDPR / UK GDPR)
If you're in the EU, EEA, UK, or any jurisdiction with similar privacy law, you have the right to access, correct, or delete the personal data we hold about you. In practice the only personal data we have is what GA4 stores, keyed by your _ga cookie — the easiest way to delete it is to clear cookies for this domain. For a formal request, contact us at the email below; we will route deletion requests to Google as the GA4 processor.
Changes
If we change what GA4 collects, add another tracker, or introduce forms or accounts that touch personal data, this page will be updated and dated before that change ships. Last updated: 2026-05-06.
