Privacy Policy
Last Updated 2026-06-16
1. Data Collection
colurnn collects information that you voluntarily provide to us and information that is automatically collected when you visit our website. Voluntarily provided information includes your email address when you subscribe to our newsletter, your name and message when you use our contact form, and any other information you choose to share with us through direct communication. Automatically collected information includes your IP address, browser type and version, operating system, referring website URL, pages visited on our site, time spent on each page, and the date and time of your visit. We collect this information through standard web server logs and analytics tools. We do not collect sensitive personal information such as financial data, health information, or government identification numbers. Our website is a blog and documentation resource — we do not process payments, manage user accounts with passwords, or store any financial credentials.
2. Use of Data
We use the information we collect for the following purposes: to deliver our newsletter to subscribers who have opted in; to respond to inquiries submitted through our contact form; to analyze website traffic and usage patterns to improve our content and user experience; to identify and fix technical issues with our website; to understand which topics and articles are most valuable to our readers so we can prioritize future content; and to comply with legal obligations when required. We do not use your personal information for automated decision-making or profiling. We do not sell, rent, or trade your personal information to third parties for their marketing purposes. Any data analysis we perform is conducted in aggregate form to understand trends and patterns, not to track or profile individual users.
3. Data Storage
Your personal data is stored on secure servers provided by our hosting and email service providers. We select providers that maintain industry-standard security certifications and data protection practices. Newsletter subscriber data is stored by our email marketing platform, which maintains SOC 2 compliance and encrypts data both in transit and at rest. Website analytics data is stored by our analytics provider and is retained for a maximum of 26 months before automatic deletion. Contact form submissions are stored in our email system and are retained for as long as necessary to respond to your inquiry and for our legitimate business records. We do not store your data longer than necessary for the purposes described in this policy. When data is no longer needed, it is securely deleted or anonymized so that it can no longer be associated with you.
4. User Rights
Depending on your jurisdiction, you may have the following rights regarding your personal data: the right to access the personal data we hold about you; the right to request correction of inaccurate or incomplete data; the right to request deletion of your personal data; the right to restrict or object to certain types of data processing; the right to data portability, allowing you to receive your data in a structured, machine-readable format; and the right to withdraw consent at any time for processing activities based on your consent. To exercise any of these rights, please contact us at [email protected]. We will respond to your request within 30 days. For newsletter subscribers, you can unsubscribe at any time by clicking the unsubscribe link included in every email we send. If you are a resident of the European Economic Area, you also have the right to lodge a complaint with your local data protection authority.
5. Third-Party Services
colurnn uses a limited number of third-party services to operate our website and deliver our content. These services may have access to certain personal data as necessary to perform their functions. Our third-party service providers include: our website hosting provider, which stores and serves our website content; our analytics provider, which helps us understand website traffic and usage patterns; our email marketing platform, which manages our newsletter subscriber list and delivers emails; and our content delivery network, which ensures fast page loading times for visitors worldwide. We carefully select third-party providers that maintain strong privacy and security practices. Each provider is contractually obligated to protect your data and use it only for the purposes we specify. We do not share your data with any third parties for advertising or marketing purposes beyond our own newsletter communications.
6. Data Security
We implement appropriate technical and organizational measures to protect your personal data against unauthorized access, alteration, disclosure, or destruction. Our security measures include: encryption of all data transmitted between your browser and our servers using TLS/SSL protocols; secure storage of personal data with encryption at rest; regular security reviews and updates of our website and infrastructure; access controls that limit employee access to personal data on a need-to-know basis; and monitoring for suspicious activity and potential security incidents. While we strive to protect your personal data, no method of transmission over the internet or method of electronic storage is completely secure. We cannot guarantee absolute security, but we are committed to implementing and maintaining reasonable security measures that reflect the sensitivity of the data we process and current industry standards.
7. Children's Privacy
colurnn is a technical blog and documentation resource designed for professional developers and business users. Our website and services are not directed at children under the age of 16, and we do not knowingly collect personal information from children under 16. If we become aware that we have inadvertently collected personal data from a child under 16, we will take immediate steps to delete that information from our systems. If you are a parent or guardian and believe that your child has provided personal information to us, please contact us at [email protected] so we can take appropriate action. We encourage parents and guardians to monitor their children's internet usage and to help enforce this policy by instructing their children to never provide personal information through our website without permission.
8. Policy Updates
We may update this Privacy Policy from time to time to reflect changes in our practices, technologies, legal requirements, or other factors. When we make material changes to this policy, we will notify you by posting the updated policy on this page with a revised 'Last Updated' date. For significant changes that materially affect how we handle your personal data, we may also provide additional notice through our newsletter or a prominent announcement on our website. We encourage you to review this Privacy Policy periodically to stay informed about how we collect, use, and protect your information. Your continued use of our website after any changes to this policy constitutes your acceptance of the updated terms. If you disagree with any changes, you should discontinue use of our website and contact us to request deletion of your personal data.
