DataLumio Blog (found at blog.datalumio.co) is operated by DataLumio, the team behind datalumio.co. This page explains what information we collect from visitors, why we collect it, and what choices you have. We wrote it in plain language on purpose — no legal jargon dump, just what’s actually happening when you read our articles on data analysis, dashboards, and data cleaning.
If anything here is unclear, reach out to us directly using the contact details near the bottom of this page.
Who This Policy Covers
This policy applies to blog.datalumio.co and any pages, forms, or tools linked from it. It does not automatically cover other DataLumio products or services hosted on datalumio.co — those may have their own privacy terms, which we’ll link to separately where relevant.
Information We Collect
We keep the list of what we collect fairly short, because we don’t need much to run a blog well.
Information you give us directly. If you subscribe to our newsletter, leave a comment, or fill out a contact form, we collect whatever you type into that form — typically your name, email address, and the content of your message.
Information collected automatically. Like most websites, our server and analytics tools pick up some technical details automatically when you visit: your IP address, browser type, device information, pages viewed, time spent on the site, and the site that referred you here. None of this identifies you personally on its own, but combined with other data it could, which is why we’re upfront about it.
Cookies and similar technologies. We use cookies (small text files stored on your device) to remember preferences, understand how visitors use the blog, and, if applicable, to support advertising. See the Cookies section below for the full breakdown.
How We Use Your Information
We use the information above to:
- Keep the blog running smoothly and troubleshoot problems when they come up
- Understand which articles are useful (and which ones fall flat) so we can write better ones
- Respond to questions submitted through contact forms
- Send newsletter updates to people who’ve asked for them
- Detect and prevent spam, abuse, or security issues
- Meet legal obligations where they apply
We don’t use your data to build a profile for resale, and we don’t sell your personal information to data brokers.
Cookies and Tracking Technologies
We may use a mix of the following, depending on what’s active on the blog at any given time:
- Essential cookies that let core site features work correctly
- Analytics cookies (for example, Google Analytics) that help us see aggregate patterns in traffic — think “how many people read this post,” not “who specifically read it”
- Advertising cookies, if we run ads through a network like Google AdSense, which may use cookies to show ads based on your browsing activity across sites
You can control or delete cookies through your browser settings at any time. Blocking cookies won’t stop you from reading the blog, though some features may behave a little differently.
Third-Party Services
We rely on a small number of outside services to keep the blog functional, and each of them may process some of your data on our behalf:
- Analytics providers (e.g., Google Analytics) to measure traffic and engagement
- Email delivery tools to send newsletters to subscribers
- Advertising networks, if ads are running on the site, to serve and measure ad performance
- Hosting and infrastructure providers that store the site’s files and databases
Each of these providers has its own privacy practices, and we choose partners who take data protection seriously. We don’t hand your information to third parties for their own independent marketing purposes.
How Long We Keep Your Data
We keep newsletter and contact form data for as long as it’s useful — generally until you unsubscribe or ask us to delete it. Analytics data is usually retained in aggregate or anonymized form after a set period, per the retention settings of the tools we use. If you’d like something deleted sooner, just ask.
Your Privacy Rights
Because our readers come from all over the world, we try to honor the stronger of whatever rights apply to you, rather than picking the bare minimum.
If you’re in the EU or UK (GDPR): You have the right to access, correct, delete, or export your personal data, to object to or restrict certain processing, and to withdraw consent at any time where processing is based on consent. You can also lodge a complaint with your local data protection authority.
If you’re in the US, particularly California (CCPA/CPRA): You have the right to know what personal information we’ve collected about you, to request deletion, to correct inaccurate information, and to opt out of the sale or sharing of personal information — which, to be clear, we don’t do.
Everyone else: Even if no specific law requires it, we’ll honor reasonable requests to access, correct, or delete your data. Just email us.
To exercise any of these rights, contact us using the details below. We’ll respond within a reasonable timeframe and may need to verify your identity first.
Children’s Privacy
DataLumio Blog isn’t directed at children, and we don’t knowingly collect personal information from anyone under 13 (or the relevant minimum age in your region). If you believe a child has provided us with personal data, contact us and we’ll remove it.
Data Security
We take reasonable technical and organizational steps to protect the information we hold — things like restricting access, using secure connections, and working with reputable service providers. That said, no method of transmission or storage is completely immune to risk, so we can’t guarantee absolute security.
International Data Transfers
Because our tools and hosting may be based in different countries, your data could be processed outside of the country you’re visiting from, including the United States. Where required, we rely on appropriate safeguards to protect data that crosses borders this way.
Links to Other Websites
Our articles sometimes link out to other sites — tools we reference, sources we cite, or resources we think you’ll find useful. Once you leave blog.datalumio.co, this policy no longer applies. We’d encourage you to check the privacy practices of any site you visit.
Changes to This Policy
We may update this page from time to time as our practices, tools, or legal requirements change. When we do, we’ll update the “Last updated” date at the top. If a change is significant, we’ll try to make it noticeable rather than burying it.
