What does this Cookie Policy cover?
This Cookie Policy explains how we use cookies and other similar technologies on our websites that link to our Privacy Policy, as well as in our emails. It also outlines your choices around managing these cookies and similar technologies.
Managing your preferences
If you are looking to manage your preferences on our Sites relating to cookies and similar technologies, you can do so by blocking cookies in your browser. Most browsers let you remove or reject cookies. To do this, follow the instructions in your browser settings. Many browsers accept cookies by default until you change your settings.
If you are looking to manage your preferences on www.bookbub.com relating to cookies and similar technologies (including opting-out), you can do so at any time here: Manage cookie preferences.
If you do not accept our cookies, you may experience some inconvenience in your use of our Site. For example, we may not be able to recognize your device, and you may need to log in every time you visit our Site.
What types of technologies does the Company use?
We may use any or all of the following "technologies" on our Site and in our emails:
Cookies:
A cookie is a very small text file that may be placed on your browser or in the storage on your device. There are two types: "session cookies" and "persistent cookies":
Session cookies are cookies that disappear from your device or browser when you close your browser.
Persistent cookies stay on your device even after you close your browser.
Please note that both the Company and third-party service providers may set cookies via our Site. These "third-party cookies" are set by domains other than those we control, and may recognize your device across different websites.
Pixel tags:
A pixel tag is a single pixel, transparent GIF image with a unique identifier that can recognize certain types of data on your device (similar to how cookies do). They are used to operate and improve the Site and our email practices, including to help deliver cookies, count visits and understand usage and email campaign effectiveness.
For example, we may include pixel tags in emails to understand how you interact with that email, such as whether you opened the email, whether you forwarded it, whether you clicked on a link in the email that directed you to our Site, etc. These pixels may collect the time, location and operating system of the device you use to read the email.
Other similar technologies:
We may also use other tracking technologies for similar purposes as described in this Cookie Policy. Such technologies include:
Local storage technologies, like HTML5, that provide cookie-equivalent functionality but can store larger amounts of data on your device outside of your browser in connection with specific applications.
Web beacons, also known as pixel tags or clear GIFs, which are used to demonstrate that a webpage or email was accessed or opened, or that certain content was viewed or clicked.
When we refer to cookies and "similar technologies" in this Cookie Policy, such reference includes reference to the pixel tags discussed above, HTML5 local storage / local shared objects, and other equivalent tracking technologies.
Why do we use cookies and similar technologies?
The purposes for which we use these technologies may fall into one of the following categories:
Strictly necessary technologies: these technologies are essential in order to enable our Site to provide the function you have requested, such as by helping to ensure that the content of a page loads quickly and effectively.
Functionality technologies: these technologies allow us to provide enhanced personalization and functionality, such as tailoring content to you, remembering your choices and preferences on the Site (e.g. language, text size, etc.) or remembering search parameters.
Analytics technologies: these technologies collect information on how users interact with our Site and enable us to improve how it operates, and improve our business more broadly. In particular, for more details about how Google uses data in the context of Google Analytics, please visit https://www.google.com/policies/privacy/partners/.
Advertising technologies: these technologies are deployed on the Site and collect information about your browsing habits in order to provide advertising which is more relevant to you and your interests. For example, they may remember the websites you have visited and share that information with other parties such as advertising technology service providers. In particular, for more details about how certain service providers use data in the context of advertising, please visit Google, Facebook, Rakuten Advertising, or AppLovin.
Social media technologies: these technologies are used when you share information using a social media sharing or "like" button on our Site or social media platform. This information may be linked to advertising activities.
How can you manage your consent?
You can control or limit how cookies and similar technologies are used by taking the following steps:
Blocking cookies in your browser. To do this, follow the instructions in your browser settings.
Managing your preferences on www.bookbub.com (including by opting-out) at any time here: Manage cookie preferences.
Pixel tags in emails can typically be blocked by default by configuring your preferences in your email client to block external images or setting it to show "plain text only" emails.

Also, to learn more about targeting and advertising cookies and your choices more widely, you can go to the Network Advertising Initiative or the Digital Advertising Alliance's WebChoices.
We retain personal information for as long as necessary to fulfill the purposes for which we collected it. These purposes may include satisfying any legal, accounting, or reporting requirements; establishing or defending legal claims; or fraud prevention.
To determine the appropriate retention period for personal information, we consider the amount, nature, and sensitivity of the personal information; the potential risk of harm from unauthorized use or disclosure of your personal information; the purposes for which we process your personal information and whether we can achieve those purposes through other means; and the applicable legal requirements.
When we no longer require the personal information we have collected about you, we will either delete or anonymize it or, if this is not possible (for example, because your personal information has been stored in backup archives), then we will securely store your personal information and isolate it from any further processing until deletion is possible. If we anonymize your personal information (so that it can no longer be associated with you), we may use this information indefinitely without further notice to you.
We are headquartered in the United States and may use service providers that operate in other countries. Your personal information may be transferred to the United States or other locations where privacy laws may not be as protective as those in your state, province, or country.
Users in the UK should also read the information provided about transfers of personal information to recipients outside the UK, contained in the Notice to UK Users section below.
You can only use Chirp if you reside in the United States or Canada.
The Sites and Services may contain links to websites, mobile applications, and other online services operated by third parties. In addition, our content may be integrated into web pages or other online services that are not associated with us. These links and integrations are not an endorsement of, or representation that we are affiliated with, any third party. We do not control websites, mobile applications, or online services operated by third parties, and we are not responsible for their actions. We encourage you to read the privacy policies of the other websites, mobile applications, and online services you use.
Our Sites are not directed at children under 18. If a parent or guardian becomes aware that their child has provided us with information without their consent, they should contact us (BookBub, Chirp), and we will delete such information as soon as reasonably practicable.
We employ technical, organizational, and physical safeguards designed to protect the personal information we collect. However, security risk is inherent in all Internet and information technologies, and we cannot guarantee the security of your personal information.
We often receive testimonials and comments from users who have had positive experiences with our Services, and we occasionally publish them. We obtain the user's consent prior to posting any feedback on a public area of our Sites.
