Sheet2 of 2

This Privacy Policy explains how FYCK Limited ("us", "we", or "our") collects, uses, and safeguards information when you use Kerno (the "Service"), including our website at kerno.io, the Kerno web application, and the Kerno CLI. By using the Service, you agree to the collection and use of information in line with this policy.

Terms used here have the same meaning as in our Terms of Service, which together with this Privacy Policy make up your agreement with us.

1. Definitions

  • Service means Kerno, operated by FYCK Limited, including the website, web application, and CLI.
  • Personal Data means data about a living individual who can be identified from that data, or from that data combined with other information in our possession.
  • Usage Data means data collected automatically, either generated by use of the Service or from the Service infrastructure itself.
  • Cookies are small files stored on your device.
  • Data Controller means the person who determines the purposes and manner in which Personal Data is processed. For this policy, we are the Data Controller of your data.
  • Data Processor means any person who processes data on behalf of the Data Controller. We may use service providers to process your data more effectively.
  • Data Subject is any living individual who is the subject of Personal Data.

2. Information We Collect

We collect several types of information to provide and improve the Service.

Personal Data

While using the Service, we may ask you to provide personally identifiable information that can be used to contact or identify you. This may include:

  • email address;
  • first name and last name;
  • billing address, state, province, ZIP or postal code, and city;
  • cookies and usage data.

Usage Data

We may also collect information that your browser or device sends when you access the Service. This Usage Data may include your IP address, browser type and version, the pages you visit, the time and date of your visit, the time spent on those pages, device identifiers, and other diagnostic data.

Cookies and Similar Technologies

We use cookies and similar technologies to operate the Service and to understand how it is used. Cookies are files with a small amount of data that may include an anonymous unique identifier. The Kerno web application uses session cookies to keep you signed in, preference cookies to remember your settings, and security cookies to protect your account. Our website and web application also use analytics cookies set by the providers named in section 12. You can instruct your browser to refuse cookies or to tell you when one is being sent, though some parts of the Service may stop working without them.

3. How We Use Your Data

FYCK Limited uses the collected data to:

  • provide and maintain the Service, and notify you about changes to it;
  • let you use interactive features of the Service;
  • provide customer support;
  • gather analysis so we can improve the Service;
  • monitor usage of the Service;
  • detect, prevent, and address technical issues;
  • carry out our obligations and enforce our rights under any contract between you and us, including billing and collection;
  • send you account and subscription notices, such as expiration and renewal notices;
  • fulfill any other purpose for which you provide the information, or any other purpose with your consent.

4. Retention of Data

We retain your Personal Data only for as long as necessary for the purposes set out in this policy, and to comply with our legal obligations, resolve disputes, and enforce our agreements. We generally retain Usage Data for a shorter period, except where it is used to strengthen security or improve the Service, or where we are legally required to keep it longer.

5. Transfer of Data

Your information, including Personal Data, may be transferred to and maintained on computers located outside your jurisdiction, where data protection laws may differ. If you are located outside the United States and provide information to us, please note that we may transfer the data to the United States and process it there. Your submission of information represents your agreement to that transfer. We take all steps reasonably necessary to ensure your data is treated securely and in line with this policy.

6. Disclosure of Data

We may disclose Personal Data we collect, or that you provide:

  • if required to do so by law or in response to valid requests by public authorities;
  • to contractors, service providers, and other third parties who support our business;
  • to fulfill the purpose for which you provided it;
  • with your consent in any other case.

7. Security of Data

The security of your data is important to us, but no method of transmission over the internet or method of electronic storage is completely secure. While we strive to use commercially acceptable means to protect your Personal Data, we cannot guarantee its absolute security.

8. Your Rights Under GDPR

If you are a resident of the European Union or European Economic Area, you have certain data protection rights. We aim to take reasonable steps to let you correct, amend, delete, or limit the use of your Personal Data. To ask what Personal Data we hold about you, or to have it removed from our systems, email us at hello@kerno.io. In certain circumstances you have the right to:

  • access, update, or delete the information we hold about you;
  • have inaccurate or incomplete information rectified;
  • object to our processing of your Personal Data;
  • request that we restrict the processing of your personal information;
  • be provided with a copy of your Personal Data in a structured, machine-readable, and commonly used format;
  • withdraw consent at any time where we rely on your consent to process your information.

We may ask you to verify your identity before responding to such a request. Please note that we may not be able to provide the Service without some necessary data. You also have the right to complain to a data protection authority about our collection and use of your Personal Data.

9. Your Rights Under CalOPPA

Under the California Online Privacy Protection Act, we agree to the following:

  • you can visit our site anonymously;
  • our Privacy Policy link includes the word "Privacy" and can be found on our website;
  • you will be notified of any privacy policy changes on this page;
  • you can change your personal information by emailing us at hello@kerno.io.

We honor Do Not Track signals. Do Not Track is a preference you can set in your web browser to tell websites that you do not want to be tracked. You can enable or disable it in your browser's settings.

10. Your Rights Under CCPA

If you are a California resident, you can learn what data we collect about you, ask us to delete your data, and ask us not to sell or share it. You can ask us to disclose:

  • the categories of personal information we have collected about you;
  • the categories of sources from which we collect it;
  • the business or commercial purpose for collecting it;
  • the categories of third parties with whom we share it;
  • the specific pieces of personal information we have collected about you.

You can also ask us to delete the personal information we hold about you. In some cases, deletion may be accomplished through de-identification. If you delete your personal information, you may not be able to use certain features that require it.

We do not sell or rent your personal information to third parties. You are the owner of your Personal Data and can request disclosure or deletion at any time. We will not discriminate against you for exercising your rights. To exercise your California rights, email us at hello@kerno.io.

11. Service Providers

We may employ third-party companies and individuals to help us provide, operate, and analyze the Service. These third parties have access to your Personal Data only to perform tasks on our behalf, and they are obligated not to disclose or use it for any other purpose.

12. Analytics

We use third-party analytics providers to understand how the Service is used. We currently use Google Tag Manager, which loads Google Analytics, and PostHog. These providers may collect information such as your device, browser, the pages you visit, and your interactions with the Service, and they process it in line with their own privacy policies. PostHog processes this data on servers in the European Union. We encourage you to review the privacy practices of Google and PostHog.

On our website at kerno.io these analytics run only after you accept them. We ask on your first visit, and you can change your answer at any time through the cookie preferences link in the footer. Rejecting analytics removes the cookies these providers have already set.

13. Payments

For paid plans, we use third-party payment processors. We do not store or collect your payment card details. That information is provided directly to our payment processors, whose use of your information is governed by their own privacy policies. Our processors adhere to the standards set by PCI-DSS, which help ensure the secure handling of payment information. We currently use Stripe, whose privacy policy is available at stripe.com/privacy.

14. Links to Other Sites

The Service may contain links to sites that we do not operate. If you click a third-party link, you will be directed to that third party's site. We have no control over, and assume no responsibility for, the content or privacy practices of any third-party site. We strongly advise you to review the privacy policy of every site you visit.

15. Children's Privacy

The Service is not intended for use by children under the age of 18. We do not knowingly collect personally identifiable information from children under 18. If you become aware that a child has provided us with Personal Data, please contact us, and if we learn that we have collected such data without parental consent, we will take steps to remove it.

16. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new policy on this page and updating the effective date above. Where appropriate, we will also let you know by email or a prominent notice on the Service before the change takes effect. You are advised to review this policy periodically.
