Most tools make you choose: capable but invasive, or private but limited. Otus takes the pragmatic route — realtime dashboards, funnels, e-commerce revenue and server-side ad conversions, without letting Google, Meta or TikTok load a single line of code in your visitors' browsers.

Most teams get here with three tools: something to measure, something to send conversions back to the ad platforms, and something to make the numbers readable. Otus is all three.
Conversion forwarding
Pragmatic, not purist
Take Google, Meta and TikTok off your site and their bidding goes blind. That's the reason most privacy migrations stall halfway: someone in performance marketing does the maths and the project quietly dies.
The purist answer is to accept the loss. Ours is to send conversions from your server instead, so the optimisation keeps running and nothing third-party ever loads for your visitors.
You decide which conversions go where. Nothing is forwarded unless you configure it, and the ad platforms only ever see what you chose to send them.
Google Ads, Meta Conversions API, TikTok Events API.
Visualizations
Prebuilt, and actually useful
Realtime, engagement, acquisition and e-commerce, ready the moment data arrives. Nobody has to configure an exploration, choose dimensions, or work out which of four similar-looking numbers is the one they meant. Every report answers a question someone actually asked.
Funnels
Build them yourself, today
Pick two to eight steps, choose your window, done. In full tracking mode the window follows a user across visits, up to seven days. In cookieless mode a session is the maximum scope, so the funnel covers a single visit.
E-commerce and custom events
Revenue, not just traffic
There's a standard set waiting for you, from view_item through purchase and refund. Send the ones your store actually uses and revenue shows up alongside the traffic. Anything outside that set, you define as a custom event.
Export
Your data, whenever you want it
Download what you need as CSV, or have a daily job push it into your warehouse. It's your data, so getting it out shouldn't be a project.
Tracking modes
Cookieless by default, so usually no banner
Otus ships cookieless. Nothing is stored in your visitors' browsers, which for most sites means there's nothing to ask permission for. Switch to full tracking mode when you need returning visitors and cross-visit funnels, and Otus works with any CMP that supports Google Consent Mode.
No third-party pixels
Your visitors meet your site, not your ad platforms
Everything above runs without Google, Meta or TikTok loading code in a browser. Conversions leave from your server, which means the ad platforms get the numbers they need and never get a foothold on your site.
Infrastructure
Hosted in Germany, end to end
Servers in Germany. No US or Chinese processors anywhere in the chain, including the models behind the AI features. That last part is where most privacy-first tools quietly fall over.
Installation
Simple to integrate
If standard tracking is all you need, integration is a small job. Drop the tag into your template, or use the GTM template, the WordPress plugin or the Shopify pixel. Nothing to build, nothing to schedule with a developer.
When you want more than the basics, adding events is well documented and stays readable. No tag manager archaeology, no fifty-page implementation guide.
Events and goals in the docsAuto-tracked events
The basics track themselves
Page views, engagement and outbound clicks come as standard, with no triggers to define or variables to map. E-commerce and custom events are yours to add when you want them.

Works with industry standard
Otus follows Google Consent Mode, so any consent platform that supports the standard works out of the box. No banner to replace, nothing to reconfigure.
Every Monday, a written report on what changed and what deserves a look. It reads your traffic, conversions and funnels the way an analyst would, and tells you the two or three things that actually moved. Aggregated data only.
Then ask it why. The chat has read access to your analytics and answers from your data, not from a search engine. Currently in beta and getting better.
Both run on EU-hosted models. Your visitors' data stays in Europe, including when the AI touches it.
