Rights under State Laws. Certain states in the U.S., including California, Colorado, Connecticut, Delaware, Florida, Indiana, Iowa, Montana, Oregon, Tennessee, Texas, Utah, and Virginia provide (or will in the future provide) their state residents with rights related to their Personal Information. Some such rights apply generally, but certain of such rights will only apply to a limited set of individuals or in limited circumstances, depending on a person’s jurisdiction of residence. To the extent that these laws apply, you may exercise the following rights:

• Right to Know and Access Information. Note that much of the information you are entitled to know or access is disclosed in this U.S. Privacy Notice. With that said, you have the right to know about our Personal Information processing practices. You also have the right to know and access the categories of Personal Information we collect, with whom we share or sell that Personal Information, and, in some cases, what specific Personal Information we associate with you or your account.
• Right to Data Portability. If you request a copy of your specific Personal Information, then we will provide it in an easily accessible format.
• Right to Deletion or Erasure. You may request that we delete the Personal Information we have collected about you. Depending on the applicable law, in some cases we are required or permitted to retain your Personal Information, even if you validly request that we delete or erase it.
• Right to Correct Information. You may request that we correct or rectify any inaccuracy in the Personal Information that we have collected about you.
• Right to Opt-out of Targeting Advertising, Sales, or Profiling. You may opt-out of our use of your Personal Information for targeted advertising, sales, or profiling in furtherance of decisions that produce legal or similarly significant effects.

To exercise any privacy rights to which you are entitled under applicable law, contact us using the contact information provided within this Privacy Notice.

Appeal. If we deny your request relating to your Personal Information, you may have the right to request an appeal of our decision, depending on your state of residence. To initiate an appeal, follow the instructions provided in the communication denying your request, or contact us using the contact information provided in this Privacy Notice.

Non-Discrimination. You may have the right not to experience discrimination by us for exercising the rights listed in this section, depending on your state of residence. What we mean by discrimination is denying you access to our Services or limiting the quality of our Services.

Email communications. You may control how you receive certain types of email communications by unsubscribing within the body of the communication. Note that some messages are required, including Service-related messages such as transaction confirmation messages, legal notices, or updates to which you may not opt-out.

This Privacy Notice applies only to our Services. Our Services may contain links to third party services including those that permit online transactions. We have no control over the privacy practices or the content of any of our business partners, advertisers, sponsors, or other third parties we link to from our Services. Checkmk does not endorse, approve, or certify these other services, and we do not guarantee the accuracy, completeness, efficacy, or timeliness of the information contained on those services. You should check the applicable Privacy Notice of the applicable third-party service provider when linking to other services.

Checkmk uses several criteria to determine how long we should keep categories of Personal Information. We may retain your Personal Information for the time period reasonably necessary to achieve the business purposes outlined in this Privacy Notice to the extent permitted by applicable law. Checkmk is under no obligation to monitor or delete information uploaded to our Services by you or other users beyond the scope required by applicable laws.

Please understand that residual copies of Personal Information can be stored in locations or formats that make complete erasure extremely difficult. The best way to ensure you control your information is to give us only the Personal Information that you are completely comfortable sharing with us.

Checkmk takes reasonable steps to secure your Personal Information. We maintain physical, electronic, and procedural safeguards to ensure that any Personal Information maintained is stored and processed responsibly. However, no internet transmission is ever fully secure, and we cannot guarantee that information transmitted via our Services will always remain confidential.

We may update or change this U.S. Privacy Notice from time to time. We will post the changes on our Services and will indicate the effective date. Your continued use of Services after the changes are effective constitutes your acceptance of the U.S. Privacy Notice as so updated.
