Privacy Policy
Last updated: October 22, 2026
Solo Stack Lab is run by one person (Shinya). This page explains what data the site's tools collect when you visit, how affiliate links work, and how we handle email you send us.
Analytics tools
We use two tools to understand how the site is used and to fix what is hard to use.
- Cloudflare Web Analytics measures page views and page-load performance. Cloudflare states that it does not track individual end users across its customers' sites. See Cloudflare's privacy policy.
- Microsoft Clarity captures how you use and interact with the site through behavioral metrics, heatmaps and session replay (for example clicks, scrolling and the pages you view). Website usage data is captured using first-party and third-party cookies and other tracking technologies. By using this site, you agree that we and Microsoft can collect and use this data. For more about how Microsoft collects and uses data, see theMicrosoft Privacy Statement.
You can limit this by blocking cookies and trackers in your browser settings or with a content blocker. We do not ask you to enter personal information anywhere on the site, and we do not use these tools to identify who you are.
Affiliate links
Some links on this site are affiliate links. When you click one, the company behind the link, or the affiliate network it uses, may set cookies or use similar technology to record that you came from this site, so that a commission can be credited if you sign up or buy. We do not control these cookies. Please read the privacy policy of the service you visit. See our affiliate disclosure for which programs we have joined.
Email you send us
If you email us, we use your email address and what you write only to reply and to check the content of your message. We do not sell it or pass it to third parties, except where the law requires it.
Links to other sites
Reviews link to the tools they cover and to other sites. We are not responsible for how those sites handle your data.
Changes to this policy
We may update this policy when the site's tools change. When we do, we change the "Last updated" date above.
