WHY SGTM

sGTM = server-side Google Tag Manager — tracking that runs on your server instead of in the visitor's browser. What does that mean? →

Up to 40% of your data quietly disappears.

Ad-blockers, ITP, and cookie restrictions choke client-side tracking. Server-side bypasses that straight from your domain — and brings back the data that was quietly slipping away.

No commitments, no excuses, nothing holds you with us. Nine concrete reasons to give it a try.

Czech support with a real human

No call center, no bots. You write and a person from the team that builds DataNostro replies directly — within 4 hours on business days.

Annual plan = 2 months free

You pay for 10 months, use 12. Up to CZK 6,000 saved a year on the BUSINESS plan.

Nothing locks you in with us

Anytime, you download all your data and your entire configuration in a single ZIP and leave. No notice period, no conditions.

Your data stays in the EU

We run in a top-tier data center in Germany. Data doesn't travel to the USA, we comply with GDPR, and we'll sign a processing agreement with you.

Invoices that suit your accountant

Invoices in CZK and EUR, imported with one click into Pohoda, Money, or ABRA. No bank currency-exchange fees.

Sklik, Heureka, and Seznam — natively
