This policy (together with our Terms of Use, Cookie Policy and any other documents referred to in it) sets out the basis on which any personal data, personally identifiable information, or personal information (“personal data”) we collect from you, or that you provide to us, through our sites will be processed by us. This policy does not cover any personal data we collect offline or that we process as a service provider for clients.

Recipients in Third Countries: The personal data that we collect or receive about you may be transferred to and processed by recipients that are located inside or outside the EEA+ and which are not recognized from an EEA+ law perspective as providing for an adequate level of data protection. When interacting with our site or contacting Oktana, you transfer personal data to the United States. To the extent your personal data are transferred to countries that do not provide for an adequate level of data protection from an EU or UK law perspective, we will base the respective transfer on appropriate safeguards (Art. 46 GDPR/UK GDPR), such as standard data protection clauses adopted by the European Commission, and any supplementary measures as necessary in order to adequately protect your personal data. You can ask for a copy of such appropriate safeguards by contacting us at trust [at] oktana [dot] com.

Period of Data Storage: Your personal data will be retained for as long as necessary to provide you with the services requested. When Oktana no longer needs to use your personal data to comply with contractual obligations, we will remove it from our systems and records and/or take steps to properly anonymize it so that you can no longer be identified from it, unless we need to keep your information, including personal data, to comply with statutory retention periods e.g. for tax purposes for a legally prescribed time period thereafter, or if we need it to preserve evidence within statutes of limitation. With regard to personal data collected through cookies or similar technologies, details are provided in the Cookie Policy.

If you have declared your consent for any personal data processing activities, you can withdraw this consent at any time with future effect.

We acknowledge the possibility, under certain conditions, for the individual to invoke binding arbitration.

CALIFORNIA CONSUMER PRIVACY ACT SUPPLEMENT

This section applies to all users (users are referred to below, simply as “you”, “your”, “yours”) who are consumers residing in the state of California, U.S., according to the “California Consumer Privacy Act of 2018” (the “CCPA”), as updated by the “California Privacy Rights Act” (the “CPRA”) and subsequent regulations. For such consumers, this section supersedes any other possibly divergent or conflicting information contained in the above privacy policy.

This portion of the document uses the term “personal information“ as defined in the California Consumer Privacy Act (CCPA/CPRA).

Notice at collection
Categories of personal information collected, used, sold, or shared

In this section we summarize the categories of personal information that we’ve collected, used, sold, or shared and the purposes thereof. You can read about these activities in detail in the section titled “Detailed information on the processing of Personal Data” within this document.

  • We have collected the following categories of personal information about you: identifiers, commercial information, internet or other electronic network activity information and employment related information.

  • We do not collect sensitive personal information.

  • We will not collect additional categories of personal information without notifying you.

Pursuant to CCPA requirements (Section 1798.140), Oktana shared the below user information categories for business reasons in the past year:

  1. Identifiers: Marketing, Service delivery

  2. Commercial Information: Service delivery, Auditing

  3. Employment-related Information: Auditing

  4. Internet Activity: Detection of security events, internal research and site optimization

Sale or sharing of your personal information

For our purposes, the word “sale” means any “selling, renting, releasing, disclosing, disseminating, making available, transferring or otherwise communicating orally, in writing, or by electronic means, a consumer’s personal information by the business to a third party, for monetary or other valuable consideration”, as defined by the CCPA. This means that, for example, a sale can happen whenever an application runs ads, or makes statistical analyses on the traffic or views, or simply because it uses tools such as social network plugins and the like. 

Oktana does not sell your personal information.

 

For our purposes, the word “sharing” means any “sharing, renting, releasing, disclosing, disseminating, making available, transferring, or otherwise communicating orally, in writing, or by electronic or other means, a consumer’s personal information by the business to a third party for cross-context behavioral advertising, whether or not for monetary or other valuable consideration, including transactions between a business and a third party for cross-context behavioral advertising for the benefit of a business in which no money is exchanged”, as defined by the CCPA.


Please note that the exchange of personal information with a service provider pursuant to a written contract that meets the requirements set by the CCPA, does not constitute a sale or sharing of your personal information.

Your right to opt out of the sale or sharing of your personal information and how you can exercise it

We sell or share your personal information with the third parties listed in detail in the section titled “Detailed information on the processing of Personal Data” within this document. These third parties are categorized in accordance with the different purposes of processing.

You have the right to opt out of the sale or sharing of your personal information. This means that whenever you request us to stop selling or sharing your personal information, we will abide by your request. Such requests can be made freely, at any time, without submitting any verifiable request. To fully exercise your right to opt out, you can contact us at any time at trust [at] oktana [dot] com.

We use any personal information collected from you in connection with the submission of your opt-out request solely for the purposes of complying with the opt-out request. Once you have opted out, we are required to wait at least 12 months before asking whether you have changed your mind.

Your privacy rights under the California Consumer Privacy Act and how to exercise them

The right to access personal information: the right to know and to portability

You have the right to request that we disclose to you:

  • the categories of personal information that we collect about you;

  • the sources from which the personal information is collected;

  • the purposes for which we use your information;

  • to whom we disclose such information;

  • the specific pieces of personal information we have collected about you.

You also have the right to know what personal information is sold or shared and to whom. In particular, you have the right to request two separate lists from us where we disclose:

  • the categories of personal information that we sold or shared about you and the categories of third parties to whom the personal information was sold or shared;

  • the categories of personal information that we disclosed about you for a business purpose and the categories of persons to whom it was disclosed for a business purpose.

The disclosure described above will be limited to the personal information collected or used over the past 12 months.

If we deliver our response electronically, the information enclosed will be “portable”, i.e. delivered in an easily usable format to enable you to transmit the information to another entity without hindrance, provided that this is technically feasible.

The right to request the deletion of your personal information

You have the right to request that we delete any of your personal information, subject to exceptions set forth by the law (such as, including but not limited to, where the information is used to identify and repair errors on Oktana web properties, to detect security incidents and protect against fraudulent or illegal activities, to exercise certain rights etc.).

If no legal exception applies, as a result of exercising your right, we will delete your personal information and notify any of our service providers and all third parties to whom we have sold or shared the personal information to do so — provided that this is technically feasible and doesn’t involve disproportionate effort.

The right to correct inaccurate personal information

You have the right to request that we correct any inaccurate personal information we maintain about you, taking into account the nature of the personal information and the purposes of the processing of the personal information.

The right to opt out of sale or sharing of personal information and to limit the use of your sensitive personal information

You have the right to opt out of the sale or sharing of your personal information. You also have the right to request that we limit our use or disclosure of your sensitive personal information.

The right of no retaliation following opt-out or exercise of other rights (the right to non-discrimination)

We will not discriminate against you for exercising your rights under the CCPA. This means that we will not discriminate against you, including, but not limited to, by denying goods or services, charging you a different price, or providing a different level or quality of goods or services just because you exercised your consumer privacy rights.

However, if you refuse to provide your personal information to us or ask us to delete or stop selling your personal information, and that personal information or sale is necessary for us to provide you with goods or services, we may not be able to continue a commercial relationship.

How to exercise your rights

To exercise the rights described above, you need to submit your verifiable request to us at trust [at] oktana [dot] com.

For us to respond to your request, it’s necessary that we know who you are. Therefore, you can only exercise the above rights by making a verifiable request which must:

  • provide sufficient information that allows us to reasonably verify you are the person about whom we collected personal information or an authorized representative;

  • describe your request with sufficient detail that allows us to properly understand, evaluate, and respond to it.

We will not respond to any request if we are unable to verify your identity and therefore confirm the personal information in our possession actually relates to you. Making a verifiable consumer request does not require you to create an account with us. We will use any personal information collected from you in connection with the verification of your request solely for the purposes of verification and shall not further disclose the personal information, retain it longer than necessary for purposes of verification, or use it for unrelated purposes.

If you cannot personally submit a verifiable request, you can authorize a person registered with the California Secretary of State to act on your behalf. If you are an adult, you can make a verifiable request on behalf of a child under your parental authority. You can submit a maximum number of 2 requests over a period of 12 months.

How and when we are expected to handle your request

  • We will confirm receipt of your verifiable request within 10 days and provide information about how we will process your request.

  • We will respond to your request within 45 days of its receipt. Should we need more time, we will explain to you the reasons why, and how much more time we need. In this regard, please note that we may take up to 90 days to fulfill your request.

  • Our disclosure(s) will cover the preceding 12-month period. Only with regard to personal information collected on or after January 1, 2022, you have the right to request that we disclose information beyond the 12-month period, and we will provide it to you unless doing so proves impossible or would involve a disproportionate effort. Should we deny your request, we will explain to you the reasons behind our denial.

  • We do not charge a fee to process or respond to your verifiable request unless such request is manifestly unfounded or excessive. In such cases, we may charge a reasonable fee, or refuse to act on the request. In either case, we will communicate our choices and explain the reasons behind it.
