Building a privacy-respecting analytics stack post-GA4

Google Analytics 4 is still the world's most-used analytics platform in 2026, but the cracks show. EU privacy authorities have fined organizations using GA4 with inadequate measures. Cookie consent banners required for GA4 drive bounce rates up. Users notice and resent third-party tracking.

The privacy-respecting alternatives are mature enough now to replace GA4 for most use cases.

What "privacy-respecting" means

• No personal data collection. No IP addresses logged (or only anonymized hashes), no fingerprinting, no third-party cookies.
• EU/local data residency. Data stored where you operate, not transferred to the US.
• No cookie banner required. If no personal data is collected, GDPR doesn't trigger consent requirement.
• Transparent. Open source preferred, clear documentation of what is collected.

Plausible Analytics

Founded specifically to be GDPR-friendly. Hosted in EU. Open source, self-host or pay $9-99/mo for cloud.

Strengths:

• Cookie-free by design.
• Simple, clean dashboard.
• Lightweight script (~1KB).
• Goals, funnels, custom events.
• Fast (sub-second dashboard load).

Weaknesses:

• No user-level analytics. Privacy benefit, analytical limitation.
• No session recording.
• Limited custom dimensions vs GA4.

Right for: Content sites, SaaS marketing pages, anywhere page-level analytics is enough.

Umami

Open-source alternative, very similar to Plausible. Self-hosted free, Umami Cloud paid.

Strengths:

• Fully self-host friendly. Runs on Postgres or MySQL.
• Multi-site dashboard.
• API for custom integrations.
• Active development.

Weaknesses:

• Less polished than Plausible.
• Smaller feature set.

Right for: Teams wanting full control via self-hosting, smaller sites.

PostHog

Open source. Behaves like a full Mixpanel/Amplitude replacement: events, funnels, session recording, feature flags, A/B testing.

Strengths:

• Comprehensive product analytics, not just page views.
• Feature flags and experimentation in same tool.
• Self-host or cloud.
• Free tier generous.

Weaknesses:

• Heavier than Plausible/Umami.
• Privacy stance is more nuanced — does collect user-level data when configured.
• Self-hosting requires more ops.

Right for: Product teams wanting full Mixpanel-like analytics with self-host option.

Matomo

Long-running, formerly Piwik. Mature, but heavier than the new generation.

Strengths:

• Most mature open-source analytics.
• Closest to GA4 in feature breadth.
• Self-host or cloud.

Weaknesses:

• UI feels dated.
• Heavier than alternatives.
• Some features require paid plugins.

Russian alternatives

For Russian/CIS audiences, two strong options:

• Yandex Metrika. Free, powerful, fast. Heatmaps, Webvisor session recording, very granular data. Tied to Yandex ecosystem.
• Self-hosted ClickHouse-based custom analytics. For teams with engineering capability — full control, no third-party.

What to track

Minimum for any site:

• Pageviews with URL.
• Referrers.
• Country (from IP, then discarded).
• Device type.
• Goals: form submissions, purchases, signups.

What's tempting but rarely useful:

• Mouse movement heatmaps (interesting once, useless after).
• Session replay (privacy hot, rarely improves decisions).
• User fingerprinting (illegal in many jurisdictions, low ROI).

Cookie consent — actually optional?

With privacy-respecting analytics that collect no personal data, you may not need a cookie banner under GDPR. ePrivacy Directive still requires consent for non-essential cookies, but if you set zero non-essential cookies, you're clear.

Plausible and Umami explicitly do not set cookies. Matomo can be configured cookie-less. PostHog requires configuration.

Result: faster pages, higher conversion, no annoying banners. Real measurable benefit.

Migration from GA4

• Run both in parallel for 2-4 weeks.
• Compare key metrics — pageviews, conversions, sources.
• Adjust dashboards based on new platform's strengths.
• Document what GA4 features won't carry over.
• Remove GA4 once team is confident.

Verdict

Plausible or Umami for content and SaaS marketing sites. PostHog for product analytics. Matomo for GA4-replacement at scale. Yandex Metrika for Russian audiences. All allow ditching the cookie banner for analytics, lifting conversion and trust simultaneously.
