7.6 Customer will promptly notify Klaviyo of any non-compliance discovered during the course of an audit and provide Klaviyo any audit reports generated in connection with any audit, unless prohibited by applicable law or otherwise instructed by a regulatory or governmental authority.

7.7 Any audits are at Customer’s expense. Customer shall reimburse Klaviyo for any time expended by Klaviyo or its Sub-processors in connection with such audits.

7.8 Klaviyo shall audit its Sub-processors on a regular basis and will, upon Customer’s request, confirm their compliance with data protection law and the obligations set upon Sub-processors according to the data processing agreement concluded with them. Customer may request Klaviyo to conduct further audits only in the event reasonably justified, and in such cases Klaviyo will conduct further audits to the extent permissible.

7.9 Customer acknowledges and agrees that, taking into account the state of the art, the costs of implementation and the nature, scope, context and purposes of processing as well as the risk of varying likelihood and severity for the rights and freedoms of natural persons, the security measures set out in Schedule 2 are appropriate to ensure the security of the Customer Personal Data. 


Klaviyo will promptly notify Customer in writing in the event of any breach of this DPA, Applicable Data Protection Laws or any instruction by Customer in connection with the processing of Customer Personal Data under this DPA. Without limiting the generality of the foregoing, Klaviyo shall notify Customer in writing without undue delay after becoming aware of any Security Incident, and reasonably cooperate in the investigation of any such Security Incident and any obligation of Customer under Applicable Data Protection Laws to make any notifications to individuals, supervisory authorities, governmental or other regulatory authority, or the public in respect of such Security Incident.

Klaviyo’s notification of or response to a Security Incident under this clause 8 will not be construed as an acknowledgement by Klaviyo of any fault or liability with respect to the Security Incident.


Klaviyo shall (a) if requested to do so by Customer by the date of termination or expiry of the Agreement, return a copy of all Customer Personal Data or provide self-service functionality allowing Customer to do the same; and (b) within 90 days of the termination or expiry of the Agreement, delete and use all reasonable efforts to procure the deletion of all other copies of Customer Personal Data processed by Klaviyo or any Sub-processors.


This DPA will commence on the Effective Date and, notwithstanding any termination of the Agreement, will remain in effect until, and automatically expire upon, Klaviyo’s deletion of all Customer Personal Data as described in this DPA.

 (c) This Addendum shall not be interpreted in a way that conflicts with rights and obligations provided for in Swiss Data Protection Laws.

 (d) Any references to legislation (or specific provisions of legislation) means that legislation (or specific provision) as it may change over time. This includes where that legislation (or specific provision) has been consolidated, re-enacted and/or replaced after this Addendum has been entered into.

2.2 Hierarchy

In the event of a conflict or inconsistency between this Addendum and the provisions of the Clauses or other related agreements between the Parties, existing at the time this Addendum is agreed or entered into thereafter, the provisions which provide the most protection to data subjects shall prevail.

2.3 Incorporation of the Clauses

 (a) In relation to any processing of personal data subject to Swiss Data Protection Laws or to both Swiss Data Protection Laws and the GDPR, this Addendum amends the DPA including as further specified in Schedule 3 of this DPA to the extent necessary so they operate:

  (i) for transfers made by the data exporter to the data importer, to the extent that Swiss Data Protection Laws or Swiss Data Protection Laws and the GDPR apply to the data exporter’s processing when making that transfer; and

  (ii) to provide appropriate safeguards for the transfers in accordance with Article 46 of the GDPR and/or Article 6(2)(a) of the Swiss Data Protection Laws, as the case may be.

 (b) To the extent that any processing of personal data is exclusively subject to Swiss Data Protection Laws, the amendments to the DPA including the SCCs, as further specified in Schedule 3 of this DPA and as required by clause 2.1 of this Swiss Addendum, include (without limitation):

  (i) References to the “Clauses” or the “SCCs” means this Swiss Addendum as it amends the SCCs and

  (ii) Clause 6 Description of the transfer(s) is replaced with:

“The details of the transfer(s), and in particular the categories of personal data that are transferred and the purpose(s) for which they are transferred, are those specified in Schedule 1 of this DPA where Swiss Data Protection Laws apply to the data exporter’s processing when making that transfer.”

  (iii) References to “Regulation (EU) 2016/679” or “that Regulation” or “GDPR” are replaced by “Swiss Data Protection Laws” and references to specific Article(s) of “Regulation (EU) 2016/679” or “GDPR” are replaced with the equivalent Article or Section of Swiss Data Protection Laws extent applicable.

  (iv) References to Regulation (EU) 2018/1725 are removed.

  (v) References to the “European Union”, “Union”, “EU” and “EU Member State” are all replaced with “Switzerland”.

  (vi) Clause 13(a) and Part C of Annex I are not used; the “competent supervisory authority” is the Federal Data Protection and Information Commissioner (the “FDPIC”) insofar as the transfers are governed by Swiss Data Protection Laws;

  (vii) Clause 17 is replaced to state:

“These Clauses are governed by the laws of Switzerland insofar as the transfers are governed by Swiss Data Protection Laws”.

  (viii) Clause 18 is replaced to state:

“Any dispute arising from these Clauses relating to Swiss Data Protection Laws shall be resolved by the courts of Switzerland. A data subject may also bring legal proceedings against the data exporter and/or data importer before the courts of Switzerland in which he/she has his/her habitual residence. The Parties agree to submit themselves to the jurisdiction of such courts.”

Until the entry into force of the revised Swiss Data Protection Laws, the Clauses shall also protect personal data of legal entities and legal entities shall receive the same protection under the Clauses as natural persons.

2.4 To the extent that any processing of personal data is subject to both Swiss Data Protection Laws and the GDPR, the DPA including the Clauses as further specified in Schedule 3 of this DPA will apply (i) as is and (ii) additionally, to the extent that a transfer is subject to Swiss Data Protection Laws, as amended by clauses 2.1 and 2.3 of this Swiss Addendum, with the sole exception that clause 17 of the SCCs shall not be replaced as stipulated under clause 2.3(b)(vii) of this Swiss Addendum.

2.5 Customer warrants that it and/or Customer Affiliates have made any notifications to the FDPIC which are required under Swiss Data Protection Laws.
