Nvivio

Nvivio is cookieless analytics from Monto Bleu BV, a Belgian private company in Tremelo that the Belgian business register shows as active since 2014. In its default mode the script sets no cookie, stores nothing on the visitor's device and never writes the IP address to disk.

A visitor is recognised by a daily code that is thrown away after 26 hours, which also means a returning visitor cannot be told from a new one. A separate cookie mode, from the Starter plan, trades that away for recognition over months and then needs consent.

The product leans on wording. The overview opens with a sentence about the period, then up to six findings that each carry the number behind them, and a comparison between two periods names the source, page, country or campaign that explains the change.

Underneath sit funnels of two to eight steps, goals with a value, a Bots page that separates AI crawlers, imports from GA4, Plausible, Umami, Fathom and Matomo, a REST API, an MCP server for assistants such as Claude, iPhone and Android apps, a WordPress plugin and a dashboard in the 24 EU languages.

The vendor is open about the stack, and it is American: the database and login run at Supabase in Frankfurt, while Cloudflare carries the script, the event queue and site settings. Both companies are US-based and rely on contractual clauses and, for Cloudflare, the Data Privacy Framework. Mistral AI in France writes the AI insights. There is no independent certification, and the free plan keeps detailed data for 30 days. Prices exclude VAT, and Belgian customers pay 21 percent.

What Nvivio does well

• Free for two sites, with every plan priced in euros from €14 a month and two months free on yearly billing
• Belgian company with a registered enterprise number and VAT number, and a published DPA and subprocessor list
• No cookies and no stored IP address by default, so no banner is needed in that mode
• REST API, MCP server, mobile apps and a WordPress plugin on offer, plus imports from five other tools
• Reports open with a sentence and name what changed, rather than leaving the reading to you

Where Nvivio falls short

• Database host Supabase and edge provider Cloudflare are both US companies, as the vendor itself states
• Visitors are only recognised within one day in the default mode, so returning visitors are not reliable
• Detailed data is kept 30 days on Free and 6 months on Starter; only daily totals last longer
• No independent security certification published, and no self-hosted edition

Standout feature. Every report starts with the question it answers, and the overview names the source or page behind a change before you open a chart.
