Needs review
Shortlist TelemetryDeck for multi-platform app analytics when on-device double-hash anonymization, cookieless signals, open SDKs, and a German-operated SaaS matter more than self-host or profile-heavy product suites. Skip when you need website-only simplicity (Plausible/Pirsch), full self-host control (Matomo/Plausible CE), or Mixpanel/Firebase-class identity and ecosystem depth—and have legal review the vendor’s “not personal data / not Art. 28 processor” DPA model plus AWS/Azure subprocessors.

Click, move, and scroll heatmaps with Attention Maps
Aggregated overlays show where visitors click, hover, and scroll. Contentsquare documents Attention Maps (engagement, not only clicks) and, on the wider platform, zone-based heatmaps that attach conversion context to page elements. Use this when a page-level bounce rate does not explain the layout. Coverage is limited to sessions the tag actually captures and to pages the recorder can reconstruct.
Session replay with claimed automatic masking
Replays mouse movement, clicks, taps, and scrolls so UX and engineering can watch a single journey. Official pages describe event-triggered recording, comments, and jump-to-replay from heatmaps or surveys. Contentsquare states that card and bank details are masked automatically. You still must suppress other personal data with blocking scripts or field exclusion. This is a browser reconstruction, not a server-side log archive.
Surveys, feedback widgets, and Engage research
On-site surveys and feedback widgets (Ask) plus user interviews and unmoderated tests (Engage). The DPA treats this as Voice of Customer. Observe and survey visitor data is hosted on AWS Ireland. Interview and user-test recordings are retained for 2 years per the DPA. Engage adds extra subprocessors (Twilio, Daily.co, Postmark, Tremendous). Response volume is plan-gated.
Funnels that open the matching recordings
Build step funnels and open sessions that converted or dropped at a step. That pairing is the reason teams keep a recorder next to GA-style charts. Advanced journey and multi-session funnel work sits on Contentsquare product analytics (Heap lineage), not on the classic Hotjar-only recorder. Funnel depth and comparison features are plan-dependent.
Error and speed context on the Contentsquare platform
The unified platform adds JavaScript error lists ranked by impact and speed analysis tied to behavior. Classic standalone Hotjar was weaker here. Full network-waterfall debugging is a platform capability. If you refuse the DXA transition you may not get this layer. Errors are only as good as what the browser tag can see.
Multi-platform SDKs and HTTP signal ingest
Official clients for Swift (Apple platforms including visionOS), Kotlin/Android, JavaScript, Flutter, React/React Native, Vue, and a one-line web snippet, with community Unity, Rust WASM, and Vapor clients. Any runtime can POST to the documented ingest API. Suits cross-platform product teams; not a drop-in replacement for a full marketing tag manager suite.
On-device salt-and-hash user anonymization
Client SDKs salt and hash user identifiers on device; the server applies a second salt and hash so neither side can reverse the original ID. App analytics docs state IPs are never stored for signals; timestamps are rounded to the hour. Limit: publishers must not put personal data in custom metadata, or the anonymization model breaks for that payload.
Cookieless app and web tracking model
No analytics cookies for product signals: apps keep a local anonymized identifier; web derives a hashed identifier from date, site, and partial IP context without storing full IPs. Aimed at leaner consent UX and simpler App Store privacy labels versus cookie-based trackers—still confirm legal posture for your jurisdiction and configuration.
Product dashboards, funnels, TQL, and notebooks
Pre-built overview and AARRR-style customer journeys (acquisition, activation, retention, revenue), technical metrics (devices, versions, errors), visual funnel builder, Explore for raw signal types, TelemetryDeck Query Language for advanced insights, and Notebooks mixing live charts with markdown. Test mode separates IDE/dev traffic from production.
Volume-based SaaS with free tier and plan retention
Commercial model is monthly event/signal volume with a free tier and paid plans that differ on included volume and how long data stays query-ready (cold storage may hold older data). Free accounts can stop ingesting when the budget is exhausted; paid plans warn and may auto-upgrade after sustained overage. Check current limits on the vendor dashboard—no self-host option.
| Assurance & compliance | Hotjar | TelemetryDeck |
|---|---|---|
| Independent security / no-logs audit | On request / NDA Vendor claims annual external penetration tests and publishes a Trust Portal with pentest reports behind access. No public independent no-logs audit (this is a recorder, not a no-logs VPN). | Not found Vendor claims no IP storage and open SDK code for inspection; no public third-party no-logs or security audit report found in this pass. |
| ISO 27001 | Vendor claimed Contentsquare states it is ISO 27001 certified (also claims ISO 27017, 27018, 27701). Certificates are on the Trust Portal; not independently downloaded for this draft. | Not found No public ISO 27001 certificate page located. |
| SOC 2 / SOC 3 | Vendor claimed Trust portal and security pages claim a SOC 2 Type II report. Report not independently downloaded. | Not found No public SOC 2/3 report located. |
| GDPR / EU data protection | Vendor claimed EU parent and contracting entity for non-Americas Hotjar Services. Public DPA, SCCs, and GDPR language. Customer is controller and must supply a lawful basis for visitor capture. | Vendor claimed EU (German) controller entity; privacy policy and Privacy FAQ document anonymization, non-storage of IPs for signals, and EU hosting regions. Vendor asserts analytics signals are not personal data—validate with counsel for your config. |
| US CLOUD Act exposure (indicative) | Partial Assessment, not a vendor slogan. French parent and no known US parent, but AWS and Azure host visitor data, Content Square, Inc. and Zendesk process support data, and US regions exist. Not legal advice. | Partial German GmbH, no known US parent, EU regions named—but public hosters include AWS and Microsoft (US groups) and HubSpot (US) for CRM. Indicative medium exposure. Not legal advice. |
| Data processing agreement (B2B) | Vendor claimed Public Contentsquare DPA incorporated by the MSA. Execution of the MSA or an order form is treated as execution of the DPA and SCCs. | Partial Public DPA at telemetrydeck.com/dpa (German AVV prevails). Document asserts TelemetryDeck is not Art. 28 processor/joint controller because signals are anonymized; TOMs on request. Not a classic processor AVV—legal review required. |
| EU AI Act | Not applicable Core product is analytics and replay, not an AI system sold as such. Sense AI and survey LLMs exist as optional features. Confirm AI Act role if you enable those modules. | Not applicable Product analytics / telemetry; not marketed as an AI system core offering. |
| CSA STAR | Vendor claimed Security page displays a STAR badge. Scope and level not independently verified. | Not listed |
| Considerations & known limitations | Hotjar | TelemetryDeck |
|---|---|---|
| No longer an independent Maltese company | High Acquired in 2021 and described as merged into Contentsquare on 1 July 2025. New contracts are Contentsquare entities. A scheduled DXA transition from 18 August 2026 can move data and retire the old UI unless you elect to stay. Practical impact: vendor risk, product roadmap, and DPA counterparty are the French group, not Hotjar Ltd. | Not listed |
| US-group cloud and US support path | Medium Visitor data sits on AWS and Azure. Zendesk (USA) and Content Square, Inc. handle support. US regions are default for some geographies. Practical impact: an Ireland region does not remove US-group infrastructure from a CLOUD Act discussion. | Not listed |
| Session replay can capture extra personal data | Medium The vendor asks customers to block non-permitted personal data and claims card masking. Misconfigured tags still record inputs or on-screen PII. Practical impact: you need a suppressions review and a consent story before go-live. | Not listed |
| SaaS tag only | Low No official self-hosted or open-source edition. Practical impact: skip this product if residency rules require your own servers. | Not listed |
| Optional LLM features add extra processors | Low Sense AI and survey AI use AWS Bedrock and Azure OpenAI. Practical impact: disable those features or map their regions if procurement treats LLMs as a separate transfer. | Not listed |
| US-group cloud and CRM subprocessors | Not listed | Medium Even with EU regions, AWS and Microsoft Azure are US-group providers; HubSpot processes customer CRM data in a US SaaS path. Buyers with strict no-US-cloud policies need written architecture confirmation or another vendor. |
| Anonymization / non-processor legal model | Not listed | Medium Public DPA states TelemetryDeck is neither processor nor joint controller for service data. Strong if true for your configuration; risky if custom metadata reintroduces personal data or if counsel disagrees with the anonymization analysis. |
| No public ISO/SOC or independent audit | Not listed | Medium No ISO 27001, SOC 2, or independent no-logs audit found publicly. Enterprise security questionnaires may need NDA materials or alternate assurance. |
| Free-tier ingest hard-stop | Not listed | Low Free plans discard events after the included monthly budget; overage data is not recoverable. Production apps on free tier need monitoring or a paid plan. |
| No self-hosted product | Not listed | Low Only client SDKs are open source. Organizations that must keep analytics databases on-prem cannot use TelemetryDeck as a full stack. |
When: You want session replay and heatmaps from an independent European vendor, not the Contentsquare group
Consider: Mouseflow
Danish SaaS with selectable EU or US Google Cloud residency and a public DPA.
When: You only need page or privacy-oriented analytics without replaying mouse paths and form fields
Consider: Plausible Analytics or etracker
Lighter measurement. Not a substitute for session replay.
When: You want a no-contract recorder and will accept a US vendor
Consider: Microsoft Clarity
Free Microsoft product. Different jurisdiction and contract posture than Content Square SAS.
When: You need a US-native event warehouse more than qualitative replay
Consider: Mixpanel or Amplitude
Product analytics incumbents. Pair with a recorder only if you still need heatmaps.
When: You only need privacy-friendly website analytics with a simple script
Consider: Plausible Analytics or Pirsch Analytics
Stronger web-first UX; weaker native multi-platform SDK story than TelemetryDeck
When: You must self-host analytics and own the database
Consider: Matomo (self-host) or Plausible Community Edition
TelemetryDeck is managed SaaS only
When: You need Firebase/Google ecosystem depth or free crash+remote-config adjacency
Consider: Firebase Analytics (accept Google jurisdiction and tracking model)
Different privacy and lock-in trade-offs
When: You need enterprise product analytics with rich identity and experimentation packaging
Consider: Mixpanel or Amplitude
Heavier privacy/cookie surface; more suite features
