TelemetryDeck

Germany· Web Analytics

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.

Swetrix

Cookieless traffic analytics with hashed sessions
Lightweight script captures pageviews, referrers/UTMs, devices, and city-level geo without cookies or client-side storage. Per the Data Policy, IP and User-Agent are hashed in memory with a daily rotating salt; only a random session id is stored—so you get sessions without long-term cross-day visitor retention.
Funnels, custom events, and goals
Instrument signups, purchases, and other conversions as custom events; build multi-step funnels and goals in the dashboard. Useful for product and growth teams who need drop-off analysis without bolting on a second product-analytics SaaS.
Real-user performance and client error tracking
Records Web Performance API timings (TTFB, DNS, TLS, render, full page load) and optional JavaScript errors with stack/context by page and browser. Bridges marketing traffic views with engineering signals that pure pageview tools omit.
Opt-in Cloud session replays with privacy modes
Cloud projects can call startSessionReplay() to record DOM and interactions; default modes mask text/inputs. Replays are not created by ordinary pageviews—customers must enable them and own consent, masking, and page exclusions. Cloud-only versus Community Edition.
AGPLv3 open source with Docker self-host CE
Core platform is public on GitHub under GNU AGPLv3; Community Edition deploys via official Docker docs with MySQL, ClickHouse, and Redis. CE includes core analytics, events, sessions, funnels, performance, and errors—but not all Cloud extras (replays, some alerts/org/AI features).
Alerts, API, GA import, and team access
Configure alerts to email, Slack, Telegram, Discord, webhooks, or push; pull or push data via the API; import GA4 history; invite organisations with roles or share password-protected/public dashboards. Fits agencies and multi-site operators who outgrow single-user tools.

TelemetryDeck

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: Swetrix vs TelemetryDeck
Assurance & compliance	Swetrix	TelemetryDeck
Independent security / no-logs audit	Not found Searched marketing, DPA, privacy, and data policy; no public independent audit PDF located. Open-source code is available for review.	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	Not found No public ISO 27001 certification claim found on primary pages.	Not found No public ISO 27001 certificate page located.
SOC 2 / SOC 3	Not found No public SOC 2/3 report found.	Not found No public SOC 2/3 report located.
GDPR / EU data protection	Vendor claimed UK company; public GDPR/PECR discussion in Data Policy; cookieless design with non-stored IPs for standard analytics; Hetzner DE hosting; public DPA. Optional replays may be personal data depending on configuration—customer assesses legal basis.	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 No known US parent; primary analytics on Hetzner DE. Material exception: Sentry (US) processes End User error data per DPA; Privacy Policy also lists AWS and OpenRouter (US) for customer email/AI. Indicative medium exposure—not a clean bill. 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 DPA at swetrix.com/dpa incorporated by Terms; acceptance by use of Service; signed copy on request.	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 web analytics, not an AI system. Optional Ask AI / OpenRouter is ancillary; confirm if your deployment enables it.	Not applicable Product analytics / telemetry; not marketed as an AI system core offering.

Considerations & known limitations: Swetrix vs TelemetryDeck
Considerations & known limitations	Swetrix	TelemetryDeck
US-group subprocessors (Sentry, AWS, OpenRouter)	Medium Primary analytics hosting is Hetzner DE, but Sentry (US) is an End User error-tracking sub-processor on the DPA, and AWS/OpenRouter appear for customer email/AI. Orgs with strict no-US-cloud rules need explicit acceptance or self-host CE to avoid those paths.	Not listed
Session replay is opt-in and controller-owned	Medium Cloud replays can capture DOM and inputs unless masked. Customers must enable startSessionReplay(), configure privacy modes/exclusions, and provide notices/consent where required—misconfiguration can reintroduce personal data risk that standard cookieless pageviews avoid.	Not listed
No public ISO/SOC or third-party audit	Medium Assurance relies on first-party policies, Hetzner infrastructure claims, and open source. Enterprise questionnaires that hard-gate on certs will stall until materials are provided under NDA or produced.	Not listed
Cloud vs Community Edition feature gap	Low Self-host CE is free and covers core analytics, but replays and several Cloud growth/ops features are limited or Cloud-only. Budget and feature planning must not assume feature parity.	Not listed
Daily salt rotation limits retention metrics	Low Cookieless design deliberately prevents classic multi-day visitor retention. Teams that need that metric class need another product or consented identity.	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.

Fit

Swetrix

Best fit when

SMEs, agencies, and product teams replacing GA4 who need cookieless traffic stats without a cookie banner driven only by analytics
Engineering-minded buyers who want error tracking and real-user performance in the same privacy-first dashboard as pageviews
Teams that may enable Cloud session replays later but can treat them as explicit opt-in with their own legal basis
Operators willing to run Docker Community Edition (MySQL/ClickHouse/Redis) when Cloud commercial terms or feature limits do not fit
Buyers who need a public B2B DPA, API access, GA4 import, and multi-channel alerts under a UK legal entity

Poor fit when

Enterprises that require published ISO 27001 / SOC 2 certificates or independent audit PDFs before shortlist
Policies that forbid any US-group subprocessors (Sentry is listed for End User error data; AWS/OpenRouter appear for customer services)
Use cases that depend on long-term cookie-based retention or cross-device identity graphs
Buyers who only want free hosted analytics with no paid Cloud tier and no self-host operations burden
Sites that will run session replays on sensitive flows without capacity to configure masking, exclusions, and consent

Consider instead when

When: You only need minimal cookieless pageviews/referrers with the smallest possible product surface
Consider: Plausible Analytics or Simple Analytics
Swetrix adds funnels, errors, RUM, and Cloud replays; peers stay closer to pure traffic analytics.
When: You need deep on-prem control, plugins, and mature enterprise self-host packaging
Consider: Matomo (self-host or managed EU hosts such as Matomo by Stackhero)
Heavier ops and optional cookies; stronger fit for large controlled deployments.
When: You must stay inside Google advertising measurement and free GA4 ecosystem tooling
Consider: Google Analytics
Trade privacy, consent, and transfer complexity for ads integration and zero software fee.

TelemetryDeck

Best fit when

Mobile/desktop/web app teams that instrument events in code (Swift, Kotlin, Flutter, RN, JS) rather than only a website script
Product orgs prioritizing cookieless, double-hashed identifiers and leaner App Store privacy narratives versus ad-tech SDKs
Teams leaving Firebase Analytics or Mixpanel who accept a simpler event model for privacy-oriented defaults
European buyers wanting a German legal entity and EU-region hosting (Azure NL, AWS Frankfurt, Hetzner DE) with public privacy docs
Indie and small teams that want a free tier to start and volume-based paid plans as signal volume grows

Poor fit when

Organizations that must self-host the full analytics stack on their own infrastructure
Website-only traffic measurement without native app SDKs (Plausible/Pirsch are usually better fits)
Buyers that require public ISO 27001/SOC 2 certificates or a conventional Art. 28 processor DPA without the vendor’s anonymization legal model
Teams needing deep identity graphs, CRM-style user profiles, or full product-analytics marketing suites
Workloads that forbid US-group cloud providers entirely (AWS and Microsoft Azure are in the public host list)

Consider instead when

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
