Mouseflow

Denmark· Web Analytics

Needs review

Shortlist when you need session replay, heatmaps, friction scoring, and journey/funnel analysis from a Danish SaaS with public DPA and pin-able EU (Belgium) or US (Iowa) Google Cloud residency. Skip when you only need cookieless pageview analytics, must avoid US-group cloud or US affiliate processing, or require self-host—consider etracker, Friendly Analytics, or a self-hosted stack instead.

Germany· Web Analytics

Needs review

Shortlist Sitesights when you need German-operated cookieless web analytics with real-time dashboards, funnels, page flow, and a server-side API—especially agencies and SaaS teams that want Hetzner Germany hosting claims without running Matomo. Skip when you need public ISO/SOC audits, long-term visitor identity, session replay, or a fully published subprocessor pack; consider Plausible Analytics or self-hosted Matomo instead.

Mouseflow

Full-session replay without sampling
Records complete visitor journeys—clicks, scrolls, navigations, device context—for later playback, starring, tagging, and sharing. Mouseflow markets 100% recording (no sampling) so rare bugs and checkout failures are not lost to traffic samples; filter by source, device, page, or friction events before reviewing.
Heatmaps with segment and period comparison
Click, scroll, movement, and attention heatmaps overlay page layouts so teams see ignored CTAs and fold issues. Compare devices, campaigns, or time ranges side by side to measure redesign impact without running a separate heatmap product.
Friction Detection and Mina AI prioritization
Automated scores surface rage clicks, dead clicks, hesitations, form abandons, and JavaScript errors, with links into the underlying replays. Mina AI answers natural-language questions about sessions and heatmaps so analysts spend less time manual-filtering queues.
Journey maps, funnels, forms, and surveys
Multi-page Journey Analytics, conversion funnels, field-level form analytics, and on-site feedback surveys sit in one workspace so drop-off diagnosis does not require four vendors. Useful for CRO and ecommerce teams closing the loop from path → leak → fix.
EU or US data residency on Google Cloud
Public subprocessors list Google Cloud EMEA Limited with Belgium (EU) and Iowa (USA) storage. Signup geography determines default region (EU customers → EU; Americas/Oceania → US). Confirm contracted region and subprocessor annex before treating residency as guaranteed.
Privacy controls, DPA, and Visual Privacy Tool
Vendor defaults include IP masking, keystroke exclusion for EU visitors, and field/element masking; customers must still audit HTML for PII. A public B2B DPA is available for electronic signature, with SCCs/DPF language for international transfers.

Sitesights

Cookieless 48-hour rotating session hash
Standard tracking does not set cookies. Sitesights generates a server-side salted hash from IP, User-Agent, and site id with a salt that rotates every 48 hours, so long-term cross-day visitor re-identification is intentionally broken. Useful when teams want essential traffic metrics without a cookie-consent banner solely for analytics—confirm legal basis with counsel for your jurisdiction and data fields (including geo).
Sub-1 KB client script plus WordPress and Shopify plugins
Drop-in client snippet marketed as under 1 KB, with official WordPress and Shopify integration paths for non-engineers. Fits marketing sites and stores that need quick instrumentation without a heavy tag manager stack.
Server-side REST API with C# and Node libraries
Send page views and events from your backend with API-key auth so ad blockers cannot strip the beacon. MIT-licensed C# and Node.js libraries on GitHub speed integration; keep API keys off the client. Preferred path for accuracy-critical SaaS and app backends.
Real-time overview with campaign and device filters
Live dashboard for visitors, pageviews, and sessions with advanced filters, UTM/campaign views, geo, browser, OS, screen size, and daytime patterns. Aimed at operators who want essential marketing analytics in one place rather than a full product-analytics suite.
Custom funnels and page-flow journey maps
Build multi-step funnels and visual page-flow maps to see entry paths, routes, and exits. Helps conversion and UX work without session replay. Depth is journey-oriented, not identity-graph product analytics.
Multi-project workspaces with roles for agencies
Group sites and apps into projects, assign roles/permissions, and invite clients or teammates. Marketing materials reference high ceilings for team seats and properties on paid plans—verify current limits on the official pricing page.

Assurance & compliance: Mouseflow vs Sitesights
Assurance & compliance	Mouseflow	Sitesights
Independent security / no-logs audit	Partial Vendor claims third-party penetration/vulnerability tests and offers a Security Kit; no public independent no-logs audit report found for download without request.	Not found No public third-party security or no-logs audit PDF located on the official site or docs.
ISO 27001	Vendor claimed Vendor states data centers maintain ISO 27001; request Security Kit for certificate scope—not independently re-verified against a public registry in this draft.	Not found No public ISO 27001 certificate found on official pages.
SOC 2 / SOC 3	Partial Privacy page mentions SOC 2 Type II-certified infrastructure; compliance/About emphasize SOC 1 Type II for data centers; FAQ prefers SOC 1 as internal standard. Confirm report type/scope via Security Kit.	Not found No public SOC 2/3 report found on official pages.
GDPR / EU data protection	Vendor claimed Danish entity; public GDPR page, DPA, IP masking, EU residency option, SCCs/DPF transfer language. Customer remains responsible for consent and PII exclusion from HTML.	Vendor claimed German controller (Drude, Grossert GbR); cookieless hashing and EU hosting claims in docs/privacy. Confirm DPA and legal basis for IP/geo with counsel.
US CLOUD Act exposure (indicative)	Partial Danish entity, no known US parent; session data on Google Cloud (Belgium/Iowa) and US affiliate Mouseflow, Inc. may process Customer Data. EU residency does not eliminate US-group cloud risk. Indicative only—not legal advice.	Partial EU entity / no known US parent; product hosting claimed on Hetzner Germany. Marketing site lists Cloudflare (US); payments via Paddle; full SaaS subprocessor list not public. Indicative only—not legal advice.
Data processing agreement (B2B)	Vendor claimed Public DPA at mouseflow.com/legal/data-processing-agreement/ with electronic signature; SCCs and DPF language included.	Not found No standalone public DPA download found during research; request under contract for B2B processing.
EU AI Act	Not applicable Behavior analytics SaaS with optional AI assistants (Mina, MCP); not positioned as a high-risk AI system product for this checklist.	Not applicable Web analytics product; not marketed as an AI system under the EU AI Act.
PCI DSS (data center)	Vendor claimed Vendor states data centers maintain PCI DSS compliance; not a substitute for customer PCI scope on payment pages—mask card fields.	Not listed

Considerations & known limitations: Mouseflow vs Sitesights
Considerations & known limitations	Mouseflow	Sitesights
Google Cloud (US-group) hosts session data	Medium Even EU-region (Belgium) storage uses Google Cloud EMEA Limited. Material for DPIAs that treat any US-group cloud as in scope for CLOUD Act/transfer analysis.	Not listed
US affiliate processes Customer Data	Medium Mouseflow, Inc. (Texas) is listed for consulting, support, maintenance, implementation, and development on Customer Data—not only a marketing office.	Not listed
Session replay can capture unexpected PII	Medium Defaults mask IPs/keystrokes/sensitive fields, but customers must audit DOM/HTML, forms, and custom variables; incidental PII is a shared-responsibility risk in this category.	Not listed
ISO/SOC claims are data-center scoped	Low Public materials emphasize infrastructure certifications; SOC 1 vs SOC 2 wording differs across pages—verify current reports rather than assuming org-wide SOC 2.	Not listed
SaaS-only (no self-host)	Low Closed multi-tenant SaaS only; no official on-prem path if residency or operator control requirements demand it.	Not listed
No public independent security audit	Not listed	Medium ISO 27001, SOC 2, and third-party security audits were not found on public pages. Enterprises may need to commission questionnaires or wait for vendor artifacts under NDA.
Incomplete public subprocessor list	Not listed	Medium Hetzner (product) and Cloudflare (marketing site) are documented; backups, email, support, and monitoring vendors for the SaaS are not fully listed. Ask for a current subprocessor annex.
US-group CDN on marketing site	Not listed	Low Privacy policy lists Cloudflare Inc. (US) for the public website CDN. Separate from claimed Hetzner product data path, but relevant to overall vendor surface area.
48-hour hash limits long-term visitor analytics	Not listed	Low By design, the rotating salt prevents durable cross-day visitor recognition. Teams needing retention cohorts or multi-week funnels by person must model events differently or choose product-analytics tools.
On-premise availability is marketing-only detail	Not listed	Low About page claims on-prem hosting; docs do not provide a self-serve install guide. Treat as sales-assisted until scope is confirmed in writing.

Fit

Mouseflow

Best fit when

CRO, UX, and ecommerce teams that need full session recordings linked to heatmaps and funnels
Mid-market orgs wanting public session-volume packaging and unlimited seats rather than per-seat DX platforms
EU buyers who can accept Google Cloud hosting if Customer Data is pinned to the Belgium region
Teams that want vendor friction scoring and Mina AI triage instead of manual replay queues only
Procurement that requires a signable DPA, SCCs/DPF language, and a published subprocessor list

Poor fit when

Sites that only need cookieless aggregate web analytics without DOM session replay
Hard sovereignty mandates that forbid US-group cloud (Google Cloud) or any US legal entity in the support path
Buyers requiring open-source or official self-hosted deployment
Enterprises standardized on Contentsquare/FullStory-class platforms who need deep custom DX integrations already covered there

Consider instead when

When: You need cookieless traffic analytics without session replay depth
Consider: etracker or Friendly Analytics
Different category focus: measurement and privacy defaults vs high-fidelity replay
When: You want free heatmaps/replays and accept Microsoft as processor
Consider: Microsoft Clarity
Lower cost of entry; different privacy and commercial model
When: You need enterprise digital-experience analytics with heavy customization
Consider: Contentsquare or FullStory
Higher implementation and procurement weight
When: You need Swiss/EU product hosts with no Google Cloud visitor path
Consider: Friendly Analytics or fusedeck
Confirm each peer’s subprocessor list independently

Sitesights

Best fit when

EU teams replacing GA4 with cookieless SaaS and wanting funnels/page-flow beyond a bare traffic counter
Agencies and freelancers managing many client sites with projects and role-based invites
Engineering-led installs that prefer server-side pageview/event ingestion against ad blockers
WordPress or Shopify properties that want official plugin paths plus a light client script
Orgs that value a German GbR legal entity and Hetzner Germany hosting claims over US multi-region analytics

Poor fit when

Product analytics requiring long-term user identity, cross-device stitching, or CDP-style profiles (48h hash by design)
Buyers who need public ISO 27001, SOC 2, or independent audit PDFs before shortlist
Teams that require self-serve open-source self-host as the primary deployment (on-prem only claimed, not documented as OSS)
UX research needs for heatmaps or session replay
Procurement that requires a complete public subprocessor list without an NDA conversation

Consider instead when

When: You want a minimal EU cookieless SaaS or a well-known self-host option
Consider: Plausible Analytics
Simpler metric set; strong self-host story. Sitesights markets deeper funnels/page-flow and multi-project agency features.
When: You need full self-host control, on-prem by default, or mature open-source governance
Consider: Matomo (self-hosted)
Heavier stack, deeper feature surface, and you operate the data plane yourself.
When: You need identity-rich product analytics, retention cohorts, or event warehouses
Consider: Mixpanel or similar product-analytics platforms
Different category—Sitesights is website/app growth analytics, not a full product analytics suite.
When: You need heatmaps, recordings, or UX feedback loops
Consider: Hotjar, Microsoft Clarity, or EU UX-analytics tools
Sitesights focuses on traffic, events, funnels, and flows—not session replay.

Open questions for due diligence

Mouseflow

Will the order form / DPA annex hard-pin EU (Belgium) residency for our account, including backups and AI features?
Which categories of Customer Data does Mouseflow, Inc. (Texas) access in day-to-day support?
Can the current ISO 27001 / SOC report package be validated (scope, dates, legal entity) via the Security Kit?
Are AI (Mina) and MCP features processed only in the same residency region as session storage?
What is the published retention default per plan and the process/SLA for deletion after offboarding?

Sitesights

Will the vendor sign a B2B DPA and provide a complete subprocessor list (backups, email, support, monitoring)?
Is the Hetzner Germany residency contractual for all analytics tenant data, including DR/backups?
What is the formal on-premise offering (SLA, update model, supported regions) versus SaaS-only?
Are any ISO 27001 / SOC 2 / penetration-test reports available under NDA?
How should geolocation fields and IP hashing be assessed under your counsel's GDPR legal-basis analysis?
