Stored answer

For a German law firm, I’d shortlist **Plausible**, **Matomo**, and **Fathom**. The right choice depends less on a “GDPR-compliant” label than on what you configure and what data you collect. | Tool | Good fit when… | Trade-off | |---|---|---| | **Plausible** | You want simple reports—visits, referrers, popular pages, and basic goals—with minimal setup. Its provider says site data is stored in Germany on EU-owned infrastructure, and its analytics are cookieless. ([ingest.plausible.io](https://ingest.plausible.io/contact?utm_source=openai)) | Less suited to detailed user journeys or complex analysis. | | **Matomo On-Premise** | You want more detailed reports and control over where analytics data is hosted. You can run it on infrastructure you manage, but you take on maintenance and security responsibilities. ([matomo.org](https://matomo.org/faq/new-to-piwik/data-sovereignty-where-your-analytics-data-is-stored/?utm_source=openai)) | More setup and administration. Its features and configuration can affect whether consent is needed. | | **Fathom** | You want a lightweight hosted service and are comfortable reviewing its processor and data-transfer documentation. Fathom says EU visitor analytics traffic is routed through an EU-based CDN. ([usefathom.com](https://usefathom.com/legal/security?utm_source=openai)) | Verify the current data flow, subprocessors, and contract terms for your firm before choosing it. | **My practical starting point:** Plausible for straightforward website statistics; Matomo On-Premise if you need richer analytics and can manage hosting. Fathom is another lightweight hosted option. **Important Germany-specific caveat:** Don’t assume that “cookieless,” “anonymous,” or EU-hosted automatically means you can skip consent. Germany’s §25 TDDDG generally requires consent to store information on, or access information from, a visitor’s device unless a narrow exception applies. German regulators have also taken a strict view of analytics in some contexts. Whether consent is required depends on the actual implementation, not just the product name. ([gesetze-im-internet.de](https://www.gesetze-im-internet.de/ttdsg/__25.html?utm_source=openai)) For a law firm, I’d also configure analytics to **exclude contact-form contents, names, email addresses, client or matter identifiers, and sensitive information in URLs**; minimize IP/device data and retention; and document the tool, purposes, lawful basis, and any processor arrangement in your privacy materials. If analytics requires consent, block it until the visitor opts in and provide an easy way to refuse or withdraw consent. Have German privacy counsel review the final setup—especially if you want analytics to run without a consent banner.
