Needs review

Shortlist Stormly when you need Dutch-contracted, e-commerce-first product analytics: SKU-aware report packs, Shopify/Adobe-oriented setup, inbox-style AI anomaly narratives, and a public DPA. Skip when you need cookieless privacy web stats only (consider Plausible, Simple Analytics, or Pirsch), open-source self-hosting, verified ISO/SOC on a public cert page, or a subprocessor chain free of US-group cloud and Azure OpenAI.

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.

Stormly

  • AI agent for trends, anomalies, and root-cause style digs

    Stormly positions an AI agent that watches connected e-commerce data for trends and anomalies (for example conversion drops or product spikes), then delivers plain-language findings—often to the inbox—with root-cause style exploration for questions like mobile conversion drops or regional return spikes. AI assistant access is plan-dependent; the public DPA documents Azure OpenAI (Microsoft) handling of assistant queries with a 30-day retention window and property stripping rules. Best for merchandising and growth leads who want narrative answers without waiting on a data team.

  • SKU-aware e-commerce report library (plus custom builds)

    Ready reports target commerce questions: New Arrivals Performance (early SKU winners/laggards), Unviewed & Unsold Products, cart abandonment and revenue contribution by product/category, Conversion Journey and funnels by device/region, A/B test insights, Aha Moment Discovery, cross-selling analysis, and broader library items (retention, CLV, forecasting, SQL report, and more). Vendor materials state custom reports are included without a separate fee when a needed view is missing—useful for mid-market retailers that outgrow generic event charts.

  • Shopify, Adobe Commerce, Segment, and GTM-oriented connections

    Homepage setup emphasizes linking Shopify, Adobe Commerce, or Segment quickly, with Google Tag Manager also listed among integrations. The DPA describes additional programmatic paths (JS library, import, custom endpoints, third-party sources). Fits stores already on common commerce stacks; teams on exotic storefronts should validate event coverage and product-feed depth in a pilot before replacing an existing analytics stack.

  • End-user tracking with IP anonymization defaults

    Per the DPA, IP addresses for end-user analytics are not stored in full: the last octet is removed and geo/timezone are derived from the anonymized value. Web integrations automatically capture first-party cookie user ids, page/referrer/UTM context, and device metadata; app properties depend on client or CDP configuration. This is still full product analytics (not cookieless aggregate-only web stats)—clients remain responsible for consent banners and lawful basis for shopper tracking.

  • Public DPA, security architecture, and Dutch contracting

    B2B buyers can download a Data Processing Agreement (effective 2023-09-06) and a Security Architecture page listing subprocessors, encryption expectations, backup retention (analytics backups up to six months), and logical tenant isolation. Contracts and DPA are governed by Dutch law with Amsterdam courts. Useful for EU procurement packages—but US-group subprocessors (AWS, Vultr, Azure OpenAI) still require transfer and CLOUD Act diligence.

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.

No public SOC 2/3 report located.

GDPR / EU data protection
Vendor claimed

NL entity; public privacy policy and DPA (GDPR-oriented); IP last-octet anonymization for end-user analytics; SCCs language for restricted transfers in DPA.

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

EU entity / no known US parent, but public client subprocessors include AWS, Vultr, and Microsoft Azure OpenAI (US-group companies). Account path historically also lists Amazon SES and Stripe. Residency claims do not remove US-group legal exposure. Indicative only—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

Downloadable DPA PDF linked from stormly.com/dpa (effective 6 September 2023); audit rights and subprocessor notice described; Security Architecture lists subprocessors.

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
Partial

Product includes an AI assistant via Azure OpenAI; not positioned as a high-risk AI system marketing claim. Buyers should map AI assistant use to their own AI Act / internal AI policy—vendor does not publish a full AI Act conformity package on the pages reviewed.

Not applicable

Product analytics / telemetry; not marketed as an AI system core offering.

Considerations & known limitations: Stormly vs TelemetryDeck
Considerations & known limitationsLogo: StormlyStormlyLogo: TelemetryDeckTelemetryDeck
US-group cloud and AI subprocessors
Medium

Despite Dutch HQ and EU residency marketing, client data paths publicly include AWS, Vultr, and Microsoft Azure OpenAI. Transfer tooling (SCCs) and encryption of backups are documented, but CLOUD Act / US legal process risk remains a diligence item for sovereignty-sensitive buyers.

Not listed
No public ISO/SOC or independent audit
Medium

Enterprise security questionnaires may stall without ISO 27001/SOC 2 packs. DPA offers information/audit rights—plan time for NDA evidence requests.

Not listed
Azure OpenAI retains assistant context 30 days
Medium

AI queries and aggregate report results are stored on Microsoft Azure OpenAI for 30 days per DPA. Property stripping reduces some identifiers, but misconfigured event properties could still expose sensitive content—govern AI use and property hygiene.

Not listed
Controller privacy policy vs security architecture drift
Low

Privacy policy (controller, effective 2019) still emphasizes Vultr USA wording in places, while Security Architecture (client data) lists Hetzner/AWS/Vultr/Azure. Ask for a single current subprocessor and region matrix at contract time.

Not listed
Not a privacy web-analytics substitute
Low

Full product analytics with cookies/identifiers for web integrations—not a cookieless aggregate counter. Consent UX remains on the client.

Not listed
US-group cloud and CRM subprocessorsNot 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 modelNot 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 auditNot 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-stopNot 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 productNot listed
Low

Only client SDKs are open source. Organizations that must keep analytics databases on-prem cannot use TelemetryDeck as a full stack.

Fit

Stormly

Best fit when

  • Merchandising, product, UX, and growth teams on Shopify or Adobe Commerce who need SKU, cart, and assortment analytics without a dedicated data science org
  • Retail brands that want ready e-commerce report templates (new arrivals, unviewed/unsold, funnels, A/B, aha moments) plus vendor-built custom reports
  • EU buyers who want a Dutch legal entity, Amsterdam courts, and a downloadable DPA/Security Architecture package
  • Teams that value AI-generated trend/anomaly narratives delivered to the inbox more than building every chart from a blank event schema
  • Stacks already using Segment or Google Tag Manager as the event pipe into analytics

Poor fit when

  • Publishers or marketing sites that only need lightweight privacy-friendly page analytics (not product/SKU depth)
  • Orgs that require open-source self-hosting or full control of a private analytics warehouse as the default
  • Procurement policies that forbid US-group subprocessors (AWS, Vultr, Microsoft Azure OpenAI) even when EU regions are claimed
  • Assurance programs that require public ISO 27001/SOC 2 evidence before pilot (not found on vendor pages reviewed)
  • Companies operating blockchain products/services—restricted by Stormly’s terms

Consider instead when

  • When: You only need privacy-oriented website metrics (pageviews, sources) rather than SKU-level product analytics

    Consider: Plausible Analytics, Simple Analytics, or Pirsch Analytics

    EU web-analytics peers; different category from e-commerce product analytics

  • When: You need deep general-purpose product analytics, large ecosystem, and mature multi-product SaaS event modeling

    Consider: Mixpanel or Amplitude

    US incumbents; stronger breadth, different jurisdiction and commercial model

  • When: You primarily need free/universal marketing acquisition reporting already embedded in the stack

    Consider: Google Analytics (incumbent) or dual-run GA for marketing + Stormly for product/merch

    GA is not SKU-first product analytics; Stormly is not a GA replacement for every report

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

Open questions for due diligence

Stormly

  • Can Stormly provide a current region map (which data classes live on Hetzner vs Vultr vs AWS) under NDA for our DPIA?
  • Are ISO 27001, SOC 2, or penetration-test summaries available on request for enterprise security review?
  • Which event properties from our Shopify/Adobe feed are excluded from Azure OpenAI prompts by default in our tenant?
  • Do custom report builds and SQL access sit only on the custom tier, and what SLAs apply?
  • Has the 2019 controller privacy policy been superseded for hosting wording relative to the Security Architecture list?

TelemetryDeck

  • Will counsel accept the public non-processor DPA/AVV model for your app’s identifier and metadata configuration?
  • Can TelemetryDeck provide TOMs, subprocessor list for the analytics plane, and any ISO/SOC or pen-test reports under NDA?
  • Which exact AWS/Azure services and accounts process customer organization data versus anonymized signals?
  • What contractual options exist to exclude or pin HubSpot and other US SaaS tools for account administration?
  • Current free-tier and paid plan event limits and retention windows for your expected volume (confirm on live plans UI)?
