How Plume shares personal information depends on the OpenSync Site used. Generally, Plume shares personal information with people and businesses that help operate the OpenSync Site and otherwise when Plume is legally permitted or required to do so.

Plume shares personal information with the following categories of recipients:

  • Professional advisors, such as lawyers, accountants, insurers and information security and forensics experts.

  • Potential or actual acquirers or investors and their professional advisers in connection with any actual or proposed merger, acquisition or investment in or of all or any part of our business. We will use our best efforts to ensure that the terms of this OpenSync Privacy Policy apply to personal information after the transaction or that users receive advance notice of changes to personal information processing.
  • Competent law enforcement, government regulators and courts when we believe disclosure is necessary (i) to comply with the law, (ii) to exercise, establish or defend legal rights, or (iii) to protect the vital interests of users, business partners, service providers or another third party.
  • Our affiliates and subsidiaries, such as Plume's entities in Poland, Slovenia, Switzerland and Taiwan.
  • Other third parties with consent.

When Plume shares anonymized data, Plume takes administrative measures to prohibit efforts by recipients to re-identify anonymized data.


Plume uses technical, physical, and administrative safeguards intended to protect the personal information that we process from unauthorized access and use.

Our safeguards are designed to provide a level of security appropriate to the risk of processing your personal information and include (as applicable) measures to ensure the ongoing confidentiality, integrity, availability, and resilience of processing systems and a procedure for regularly testing, assessing and evaluating the effectiveness of technical and organizational measures for ensuring the security of the processing of personal information. Like any other organization, Plume cannot fully eliminate security risks associated with the processing of personal information.

You are responsible for maintaining the security of your account credentials. Plume will treat access to the OpenSync Site through your account credentials as authorized by you.

We may suspend your use of all or part of the OpenSync Site without notice if we suspect or detect any breach of security. If you believe that information you provided to Plume or your account is no longer secure, please notify us immediately at [email protected].

If we become aware of a breach that affects the security of your personal information, we will provide you with notice as required by applicable law. When permitted by applicable law, Plume will provide this notice to you through the email address associated with your account or other permitted method associated with your account.



Plume retains personal information for as long as necessary to carry out the purposes described above. Plume also retains personal information for as long as Plume believes necessary to comply with our legal obligations, resolve disputes and enforce our legal agreements.

When determining the relevant retention period, Plume considers a user's purpose for using the OpenSync Site, retention periods in Plume's data deletion procedures and requirements of data protection laws.

At the end of the relevant retention period, Plume either deletes or anonymizes personal information or, if Plume cannot delete or anonymize the personal information, then Plume segregates and securely stores personal information until deletion or anonymization is possible. Plume uses anonymized data subject to applicable law.


Choices about personal information depend on a user's place of habitual residence and the applicable OpenSync Site.

(i) Plume needs the personal information to perform a contract (such as the OpenSync Terms of Use)

We may have other legitimate interests and if appropriate we will make clear our legitimate interests at the relevant time.

In some cases, we also may have a legal obligation to collect personal information from users. If we ask you to provide personal information to comply with a legal requirement, we will make this clear at the relevant time and advise you whether providing your personal information is mandatory and the possible consequences if you do not provide your personal information.
