Privacy Policy

Short version: We only collect the information you choose to give us, and we process it with your consent, or on another legal basis; we only require the minimum amount of personal information that is necessary to fulfill the purpose of your interaction with us; we don't sell it to third parties; and we only use it as this Privacy Statement describes.

What Information Nextjournal Collects and Why


Information From Website Browsers

If you're just browsing the website, we collect the same basic information that most websites collect. We use common internet technologies, such as cookies and web server logs. This is stuff we collect from everybody, whether they have an account or not.

The information we collect about all visitors to our website includes the visitor’s browser type, language preference, referring site, additional websites requested, and the date and time of each visitor request. We also collect potentially personally-identifying information like Internet Protocol (IP) addresses.

We collect this information to better understand how our website visitors use Nextjournal, and to monitor and protect the security of the website.


Information From Users With Accounts

If you create an account, we require some basic information at the time of account creation. You will create your own user name and password, and we will ask you for a valid e-mail address. You also have the option to give us more information if you want to, and this may include "User Personal Information."

"User Personal Information" is any information about one of our users which could, alone or together with other information, personally identify him or her. Information such as a user name and password, an e-mail address, a real name, and a photograph are examples of “User Personal Information.” User Personal Information includes Personal Data as defined in the General Data Protection Regulation.

User Personal Information does not include aggregated, non-personally identifying information. We may use aggregated, non-personally identifying information to operate, improve, and optimize our website and service.


Why We Collect This Information

  • We need your User Personal Information to create your account, and to provide the services you request, including to provide the Nextjournal service or to respond to support requests.
  • We use your User Personal Information, specifically your user name, to identify you on Nextjournal.
  • We use it to fill out your profile and share that profile with other users if you ask us to.
  • We will use your e-mail address to communicate with you, if you've said that's okay, and only for the reasons you’ve said that’s okay. Please see our section on e-mail communication for more information.
  • We use your User Personal Information for internal purposes, such as to maintain logs for security reasons, for training purposes, and for legal documentation.
  • We limit our use of your User Personal Information to the purposes listed in this Privacy Statement. If we need to use your User Personal Information for other purposes, we will ask your permission first. You can always see what information we have, how we're using it, and what permissions you have given us in your user profile.


Our Legal Basis For Processing Information

Under certain international laws, Nextjournal is required to notify you about the legal basis on which we process User Personal Information. Nextjournal processes User Personal Information on the following legal bases:

  • When you create a Nextjournal account, you provide your user name and an e-mail address. We require those data elements for you to enter into the Terms of Service agreement with us, and we process those elements on the basis of performing that contract. We also process your user name and e-mail address on other bases. If you have a paid account with us, there will be other data elements we must collect and process on the basis of performing that contract. Nextjournal does not collect or process a credit card number, but our third-party payment processor does.
  • When you fill out the information in your user profile, you have the option to provide User Personal Information such as your full name, an avatar which may include a photograph, your biography, and a URL to a third party website. We process this information on the basis of consent. All of this information is entirely optional, and you have the ability to access, modify, and delete it at any time.
  • Generally, the remainder of the processing of personal information we perform is necessary for the purposes of our legitimate interests. For example, for security purposes, we must keep logs of IP addresses that access Nextjournal, and in order to respond to legal process, we are required to keep records of users who have sent and received DMCA takedown notices.
  • If you would like to request erasure of data we process on the basis of consent or object to our processing of personal information, please contact us.

What Information Nextjournal Does Not Collect

We do not intentionally collect sensitive personal information, such as social security numbers, genetic data, health information, or religious information. Although Nextjournal does not request or intentionally collect any sensitive personal information, we realize that you might store this kind of information in your account, such as in an article or in your public profile. If you store any sensitive personal information on our servers, you are responsible for complying with any regulatory controls regarding that data.

If you're a child under the age of 13, you may not have an account on Nextjournal. Nextjournal does not knowingly collect information from or direct any of our content specifically to children under 13. If we learn or have reason to suspect that you are a user who is under the age of 13, we will unfortunately have to close your account. Please see our Terms of Service for information about account termination. Other countries may have different minimum age limits, and if you are below the minimum age for providing consent for data collection in your country, you may not use Nextjournal without obtaining your parents' or legal guardians' consent.

We do not intentionally collect User Personal Information that is stored in your articles or other free-form content inputs. Information in your articles belongs to you, and you are responsible for it, as well as for making sure that your content complies with our Terms of Service. Any personal information within articles a user has created or contributed to is the responsibility of the repository owner.


Repository Contents

Nextjournal employees do not access private articles unless required to for security reasons, to assist the article owner with a support matter, or to maintain the integrity of the service. Our Terms of Service provides more details.

If your article is public, anyone (including us and unaffiliated third parties) may view its contents. If you have included private or sensitive information in your public article, such as e-mail addresses or passwords, that information may be indexed by search engines or used by third parties. In addition, while we do not generally search for content in your articles, we may scan our servers for certain tokens or security signatures, or for known active malware.

How we share the information we collect

We do share User Personal Information with your permission, so we can perform services you have requested or communicate on your behalf. For example, if you purchase an additional service on our platform, we will share your account name to allow the integrator to provide you that service.

We do not share, sell, rent, or trade User Personal Information with third parties for their commercial purposes.

We do not host advertising on Nextjournal. An article may occasionally embed content from third party sites, such as YouTube, and that content may include ads. While we try to minimize the amount of ads our embedded content contains, we can't always control what third parties show. Any advertisements on individual Nextjournal pages or in Nextjournal articles are not sponsored by, or tracked by, Nextjournal.

We do not disclose User Personal Information outside Nextjournal, except in the situations listed in this section or in the section below on Compelled Disclosure.

We do share certain aggregated, non-personally identifying information with others about how our users, collectively, use Nextjournal, or how our users respond to our other offerings, such as our conferences or events. For example, we may compile statistics on the usage of open source licenses across Nextjournal. However, we do not sell this information to advertisers or marketers.

We do share User Personal Information with a limited number of third party vendors who process it on our behalf to provide or improve our service, and who have agreed to privacy restrictions similar to our own Privacy Statement by signing data protection agreements. Our vendors perform services such as payment processing, customer support ticketing, network data transmission, and other similar services. While Nextjournal processes all User Personal Information in the United States, our third party vendors may process data outside of the United States or the European Union.

We may share User Personal Information if we are involved in a merger, sale, or acquisition. If any such change of ownership happens, we will ensure that it is under terms that preserve the confidentiality of User Personal Information, and we will notify you on our website or by e-mail before any transfer of your User Personal Information. The organization receiving any User Personal Information will have to honor any promises we have made in our Privacy Statement or in our Terms of Service.


Public information on Nextjournal

Much of Nextjournal is public-facing. If your content is public-facing, third parties may access and use it in compliance with our Terms of Service, such as by viewing your profile or articles or pulling data via our API. We do not sell that content; it is yours. However, we do allow third parties, such as research organizations or archives, to compile public-facing Nextjournal information.

Your Personal Information, associated with your content, could be gathered by third parties in these compilations of Nextjournal data. If you do not want your Personal Information to appear in third parties’ compilations of Nextjournal data, please do not make your Personal Information publicly available

If you would like to compile Nextjournal data, you must comply with our Terms of Service regarding scraping and privacy, and you may only use any public-facing Personal Information you gather for the purpose for which our user has authorized it. For example, where a Nextjournal user has made an e-mail address public-facing for the purpose of identification and attribution, do not use that e-mail address for commercial advertising. We expect you to reasonably secure any Personal Information you have gathered from Nextjournal, and to respond promptly to complaints, removal requests, and "do not contact" requests from Nextjournal or Nextjournal users.

Similarly, projects on Nextjournal may include publicly available Personal Information collected as part of the collaborative process. In the event that a Nextjournal project contains publicly available Personal Information that does not belong to Nextjournal users, we will only use that Personal Information for the limited purpose for which it was collected, and we will secure that Personal Information as we would secure any User Personal Information. If you have a complaint about any Personal Information on Nextjournal, please see our section on resolving complaints.

How You Can Access and Control the Information we Collect

If you're already a Nextjournal user, you may access, update, alter, or delete your basic user profile information by editing your user profile or contacting support. You can control the information we collect about you by limiting what information is in your profile and by updating out of date information.

Data Portability

As a Nextjournal User, you can always take your data with you.


Data Retention and Deletion of Data

Generally, Nextjournal will retain User Personal Information for as long as your account is active or as needed to provide you services.

We may retain certain User Personal Information indefinitely, unless you delete it or request its deletion. For example, we don’t automatically delete inactive user accounts, so unless you choose to delete your account, we will retain your account information indefinitely.

If you would like to cancel your account or delete your User Personal Information, you may do so in your user profile. We will retain and use your information as necessary to comply with our legal obligations, resolve disputes, and enforce our agreements, but barring legal requirements, we will delete your full profile (within reason) within 90 days. You may contact us to request the erasure of the data we process on the basis of consent within 30 days.

After an account has been deleted, certain data, such as contributions to others' articles and transcluded elements, will remain.

Our Use of Cookies and Tracking


Nextjournal uses cookies to make interactions with our service easy and meaningful. We use cookies (and similar technologies, like HTML5 localStorage) to keep you logged in and remember your preferences. We also use cookies to identify a device, for security reasons. By using our website, you agree that we can place these types of cookies on your computer or device.

Tracking and Analytics

We use a number of third party analytics and service providers to help us evaluate our users' use of Nextjournal, compile statistical reports on activity, and improve our content and website performance. We only use these third party analytics providers on certain areas of our website.

We do not currently respond to your browser's Do Not Track signal, and we do not permit third parties other than our analytics and service providers to track Nextjournal users' activity over time on Nextjournal. We do not track your online browsing activity on other online services over time.


How Nextjournal Secures Your Information

Nextjournal takes all measures reasonably necessary to protect User Personal Information from unauthorized access, alteration, or destruction; maintain data accuracy; and help ensure the appropriate use of User Personal Information.

In the event of a data breach that affects your User Personal Information, we will act promptly to mitigate the impact of a breach and notify any affected users without undue delay.

Transmission of data on Nextjournal is encrypted using SSH, HTTPS, and SSL/TLS but no method of transmission, or method of electronic storage, is 100% secure. Therefore, we cannot guarantee its absolute security.


Nextjournal's Global Privacy Practices

We store and process the information that we collect in Germany in accordance with this Privacy Statement (our subprocessors may store and process data outside of Germany). However, we understand that we have users from different countries and regions with different privacy expectations, and we try to meet those needs even when Germany does not have the same privacy framework as other countries'.

We provide the same standard of privacy protection — as described in this Privacy Statement — to all our users around the world, regardless of their country of origin or location. We collect only the minimum amount of personal data necessary for our purposes, unless you choose to provide more. We encourage you to only give us the amount of data you are comfortable sharing. We offer you simple methods of accessing, correcting, or deleting the User Personal Information we have collected. We provide our users notice, choice, accountability, security, and access, and we limit the purpose for processing.


How We Respond to Compelled Disclosure

Nextjournal may disclose personally-identifying information or other information we collect about you to law enforcement in response to a valid subpoena, court order, warrant, or similar government order, or when we believe in good faith that disclosure is reasonably necessary to protect our property or rights, or those of third parties or the public at large.

In complying with court orders and similar legal processes, Nextjournal strives for transparency. When permitted, we will make a reasonable effort to notify users of any disclosure of their information, unless we are prohibited by law or court order from doing so, or in rare, exigent circumstances.


How We, and Others, Communicate With You

We will use your e-mail address to communicate with you, if you've said that's okay, and only for the reasons you’ve said that’s okay. For example, if you e-mail our Support team with a request, we will respond to you via e-mail.

Depending on your e-mail settings, Nextjournal may occasionally send notification e-mails about new features, important policy changes, or offer customer support.

We also use Intercom, a third party platform, to offer customer support. Please see their privacy policy to see how contacting us on this platform affects your privacy.

Resolving Complaints

If you have concerns about the way Nextjournal is handling your User Personal Information, please let us know immediately. We want to help. You may e-mail us directly at with the subject line "Privacy Concerns." We will respond promptly — within 45 days at the latest.


Changes to our Privacy Statement

Although most changes are likely to be minor, Nextjournal may change our Privacy Statement from time to time. We will provide notification to Users of material changes to this Privacy Statement through our Website at least 30 days prior to the change taking effect by posting a notice on our home page or sending e-mail to the primary e-mail address specified in your Nextjournal account. For changes to this Privacy Statement that do not affect your rights, we encourage visitors to check our Site Policy repository frequently.
