Nimbata
Nimbata is a US based call tracking and conversation analytics platform. It performs Dynamic Number Insertion on websites to attribute phone calls to marketing channels, records and transcribes calls and stores caller metadata. Because call data is processed in the United States and includes recordings, prior consent and Article 46 GDPR transfer safeguards are required.
What does Nimbata do?
What Nimbata does and how it processes data
Nimbata is a call tracking and conversation analytics platform aimed at marketers who want to attribute inbound phone calls to the campaigns, keywords or pages that triggered them. After installing a JavaScript snippet on the site, Nimbata performs Dynamic Number Insertion (DNI): each visitor sees a unique tracking number that forwards to the operators real phone line. Calls are routed through Nimbata, where they are recorded, transcribed, scored and attributed back to the original marketing source.
Cookies and trackers set by Nimbata
The Nimbata script sets first party and third party cookies plus localStorage entries that identify the visitor, store the source attributes (utm, gclid, fbclid, referrer) and persist the assigned tracking number for the session. These cookies are not strictly necessary: they exist for advertising attribution. They therefore require prior opt in consent under Article 5(3) of the ePrivacy Directive and Article 7 GDPR before any value is written to the browser.
Call recording, transcription and special category risk
Nimbata also captures the call audio and produces a written transcript. Both are personal data under the GDPR, and the spoken content may unexpectedly reveal special category data (health, religion, political opinions). In France, Germany, Spain and the UK the supervisory authorities expect a clear announcement before the call is recorded, the option to object, and a documented retention period. Sensitive content such as health complaints must trigger additional safeguards under Article 9 GDPR.
International data transfers
Nimbata is a United States company and processes call recordings, transcripts and tracking data on AWS US regions. Transfers from the EEA to the United States require an Article 46 GDPR safeguard. The most common path is the EU US Data Privacy Framework if Nimbata is certified, otherwise the EU Standard Contractual Clauses with a transfer impact assessment. Document the chain in the record of processing activities and inform the data subjects in the privacy notice.
Practical compliance steps
Gate the Nimbata snippet behind a Consent Management Platform so it loads only after opt in. Add a clear pre call announcement (recorded message or human prompt) and offer a way to continue without recording. Sign a Data Processing Agreement with Nimbata, list it in the record of processing as a US processor and document the transfer safeguard. Restrict access to the recordings to specifically named users, set a retention policy (typically 6 to 12 months) and purge older calls automatically.
Alternatives and exit strategy
EU based alternatives include CallTrackingMetrics with EU residency, Dialogtech, Salesmsg with EU hosting, AdCalls (NL), Adversitement and Aircall (FR). They reduce the transfer risk but still require consent for the cookies and an announcement for the recording. Plan an exit strategy by exporting call data and recordings in a standard format and by signalling the change in the cookie policy.
Nimbata and the GDPR
Nimbata is classified as “Analytics”. On a site that targets European visitors, it must only load after the visitor consents, and it must be listed in your cookie policy.
- Legal basis
- Article 6(1)(a) GDPR (consent) for call tracking cookies and analytics; Article 6(1)(f) GDPR (legitimate interest) for the underlying business use, balanced against the call recording obligations; Article 6(1)(a) GDPR specific consent (often opt in announcement) for call recording itself.
- Risk level
- high
- Applicable regulations
- GDPR, ePrivacy Directive 2002/58/EC, national rules on call recording (CNIL guidance in France, BDSG in Germany, AEPD guidance in Spain, ICO guidance in the UK)
Impact assessment (DPIA)
A DPIA is recommended because Nimbata combines call recording, transcription and behavioural tracking, three operations that the EDPB and several supervisory authorities consider high risk individually. Document the recording purpose, the retention period, the access controls inside Nimbata, the announcement message to the caller, and the US data transfer chain. Reassess the DPIA when adding speech analytics, sentiment scoring or automated lead routing.

What Nimbata sets and contacts
- Tracking method
- JavaScript snippet performing Dynamic Number Insertion (DNI) on website pages, plus first party and third party cookies that link a visitor session to the inbound phone call. Calls themselves are captured server side through Nimbata phone numbers; recordings, transcripts and caller metadata are stored in the Nimbata back end.
- Server location
- United States (Nimbata operates from the US with cloud infrastructure on AWS US regions)
- Data transferred outside the EU
- Personal data, including caller phone numbers, call recordings and transcripts, is transferred to the United States. Transfers must be covered by Article 46 GDPR safeguards (EU Standard Contractual Clauses plus a transfer impact assessment) or by the EU US Data Privacy Framework if Nimbata is certified.

Frequently asked questions about Nimbata
Can't find your question? Write to us, we answer fast.
What cookies and trackers does Nimbata install on my site?
Nimbata sets first party and third party cookies plus localStorage entries on every page where the script is active. They identify the visitor (a nimbata_visitor id), persist the attribution parameters (utm, gclid, fbclid, referrer) and reserve a tracking phone number for the session. Some flows also load Google Analytics and Facebook pixels triggered by Nimbata. All of these are non essential cookies and require prior opt in consent.
Do I need consent before loading Nimbata?
Yes. The tracking cookies are not strictly necessary because they exist for advertising attribution, not for delivering the requested service. Article 5(3) of the ePrivacy Directive and Article 7 GDPR require prior opt in consent before any value is written to the visitor browser. Gate the snippet behind a Consent Management Platform and only load it after a clear opt in.
What is the lawful basis for processing through Nimbata?
Two stacked bases usually apply. Consent (Article 6(1)(a) GDPR) covers the cookies and the analytics. Legitimate interest (Article 6(1)(f) GDPR) can cover the underlying marketing measurement once consent has been obtained, but it does not replace the consent requirement for cookies and call recording. The call recording itself often requires its own explicit consent or strict legitimate interest with a clear announcement, depending on the Member State.
Does Nimbata transfer data to the United States?
Yes. Nimbata is a US company and hosts call recordings, transcripts and tracking data on AWS US regions. The EEA to US transfer must be covered by a valid Article 46 GDPR safeguard, either the EU US Data Privacy Framework (if Nimbata is certified) or the EU Standard Contractual Clauses combined with a documented transfer impact assessment. The transfer must be disclosed in the privacy notice.
Do I need a DPIA for Nimbata?
Yes, a DPIA is strongly recommended. Nimbata combines large scale online tracking, call recording and automated transcription, three operations the EDPB places on the list of high risk processing. Document the recording purpose, the retention period, the access controls inside Nimbata, the announcement message to the caller and the US transfer chain.
How do I implement Nimbata compliantly?
Block the Nimbata snippet by default and only load it after granular opt in. Add a pre call announcement (recorded or live) and offer a no recording path. Sign a Data Processing Agreement with Nimbata, list it in the record of processing as a US processor, document the transfer safeguard. Restrict back office access to specifically named users, set a 6 to 12 month retention period for recordings and purge older calls automatically.
What are GDPR friendly alternatives to Nimbata?
EU oriented alternatives include CallTrackingMetrics with EU residency, Dialogtech, AdCalls (Netherlands), Adversitement, Aircall (France), Sipgate and Salesmsg with EU hosting. They reduce transfer risk but do not remove the consent and announcement requirements. Server side call attribution with anonymised number pools is another option for low risk use cases.
How do I update my cookie policy after adding Nimbata?
Add a Nimbata section to the cookie policy that lists each cookie (name, purpose, duration, third party), explains the call recording, names the US processor and references the transfer safeguard. Map the lawful basis (consent for the cookies and the recording), the retention period and the data subject rights. Update the privacy notice and the record of processing activities in the same release and rerun your cookie scanner to confirm the inventory.
