WhatConverts review 2026: price, GDPR and when call tracking is worth it

WhatConverts is an American lead tracking tool that gathers calls, forms, chat and e-commerce in one place. The strength is call tracking: the tool swaps the phone number on the site depending on where the visitor came from, so every call can be tied back to ad, campaign and ideally keyword. For ad-driven businesses it is one of the few solutions that really answers the question “which ad gave the customer?”.

What impresses

The attribution is broad: calls, forms, chat and e-commerce land in the same view, and user ratings are among the highest in the category: 4.9 out of 5 on both G2 and Capterra. Smartest of all is the feedback loop to Google Ads: qualified leads can be sent back as conversions, so bidding is trained on real business rather than clicks.

The company behind it is bootstrapped and profitable since 2014, with no venture capital owners, which usually means a stable product that does not pivot every other year. The security work is SOC 2 Type 2 audited and a data processing agreement exists in the EU version.

What concerns us

The list is heavier here, and for Swedish conditions it is decisive.

All data is stored and processed in the USA (AWS) under US law. The privacy policy states no transfer mechanism for EU data, which is a red flag in our Schrems III traffic light. That is not a footnote but the core of the assessment below.

Prices are in USD and usage fees are added on top of the subscription. Swedish numbers cost about USD 3 per number and month plus 6 cents per minute, which makes the total monthly cost hard to predict. For a business with many incoming calls, the usage fees can quickly exceed the subscription itself. On top of that, the entry plan at about USD 30 only tracks calls and SMS; if you want form tracking, Plus at about USD 60 is required.

Less dramatic but worth knowing: the interface is English-only, call recording requires an active consent setup in Sweden, and international tracking numbers normally require address verification, which is extra friction right at the start, when you most want to get going quickly.

Who should choose something else?

Start here, because it is the most important line to draw: healthcare clinics, law firms and others where the calls themselves are sensitive personal data should not place recorded patient calls or client conversations on American servers without a clear transfer mechanism. If the Schrems III question is decided badly, that is the wrong place to be.

What remains is the group WhatConverts is actually built for: businesses that advertise for tens of thousands of kronor per month, live on incoming calls, want to know exactly which campaign and keyword generate leads, and can accept USA data storage and USD prices. For them, the tool is in a class of its own.

Three alternatives with different strengths

• Matomo: EU-based analytics with multi-channel attribution in the cloud plan from EUR 29/month. No call tracking, but good for forms and clicks.
• Plausible: simple, cookie-free and cheap from USD 9/month. All data in Europe. No deep attribution or call tracking.
• Google Analytics 4: free and powerful, but data is processed in the USA and IMY has already sanctioned Swedish companies for unlawful use.

Verdict: 3.1 out of 5

The product quality justifies a considerably higher score. In our review of the field, WhatConverts is one of the most complete lead tracking tools, especially for phone. But the rating is set for Swedish conditions, and there the USA data storage, the unclear transfer terms and the variable USD costs drag down the whole. If you advertise heavily by phone and have good control of data protection issues it can be a strong choice. In all other cases: start with UTM parameters and an EU-friendly analytics tool.
