Privacy Policy
What data 9sBlog handles and why: server request logs, a coarsened IP prefix on comments, and the settings your own browser keeps. No accounts, and updated as the site changes.
9sBlog is a technology blog. It has no accounts to sign up for and asks for no personal information to read it. This page explains the data the site handles, because “we take your privacy seriously” means nothing without saying what actually happens — and it is kept current as the site changes.
Where “we”, “us” and “the site” appear below, they mean 9sblog.com.
The short version
- No accounts, no logins, no newsletter, no sign-up of any kind.
- The fonts are served from this site, not from Google, so reading a page does not report you to a third party.
- The only data you actively hand over is a comment, if you choose to leave one.
- When advertising is enabled, Google AdSense and its partners may set cookies to show ads; you can opt out (see Advertising below).
- When new services are added to the site, this page is updated to describe them before they go live.
What is collected, and why
Server request logs. Like every website, the server records the requests it receives — the page asked for, the time, the browser’s user-agent string, and the network address it came from. These logs exist to keep the site running and to spot abuse, and they rotate and are deleted on a short schedule. The site sits behind Cloudflare, which also processes requests in order to serve and protect the site; Cloudflare’s own handling is covered by its privacy policy.
Comments. If you leave a comment, the site stores the name you type, the comment text, and the time. It also stores a coarsened version of your network address — only the first three groups of an IPv4 address (for example 203.0.113.0), which is enough to slow down spam but not enough to identify you. Comments are held and read before they appear. Nothing about a comment is published except the name you chose and the words you wrote; the address prefix is never shown. Ask, and your comment and the data attached to it will be removed.
Settings you keep in your own browser. The colour theme, your reading list, and any reactions you tap are stored in your browser’s local storage on your own device. They never reach the server, are never sent anywhere, and are visible only to you. Clearing your browser’s site data clears them.
Search. The on-site search runs entirely in your browser against a prebuilt index. What you type into it is not sent to the server and is not recorded.
Cookies and third parties
The site’s own pages set no first-party tracking cookies. Some cookies can still be set:
- Cloudflare may set a security cookie (such as
__cf_bm) to tell automated abuse from real visitors. - Third-party services. Some articles link out to other sites, and some pages may embed or load services provided by other companies. Following an outbound link, or a service loaded into a page, can let that third party set its own cookie under its own privacy policy — this only involves data you send to, or interactions you have with, that third party. Where an outbound link earns the site a commission, the article says so at the link. Any such service the site relies on is named here.
Advertising
This site is supported in part by advertising, served by Google AdSense. Google and third-party vendors use cookies and similar technologies to serve ads based on your prior visits to this and other websites, so the ads you see may be tailored to your interests. You can turn off personalized advertising at Google Ads Settings, review how Google uses data from sites that use its services at Google’s partner-sites page, and opt out of other third-party ad cookies at aboutads.info. For visitors in the EEA, the UK, and Switzerland, a consent prompt asks your choices before any advertising cookies are set. Advertising cookies are third-party; the site’s own pages still set no first-party tracking cookies.
Affiliate links
Some articles include affiliate links. If you follow one and buy something, the site may earn a commission — the price you pay is exactly the same. Any article that carries affiliate links shows a clear note saying so at the top. A commission never decides what the site recommends; suggestions are based only on what actually helps.
Your requests
To have a comment and the data attached to it removed, or to ask what is held about you, write to [email protected]. Requests are handled without a lawyer and without a form.
Changes
If this policy changes, the updated version replaces this page and the date below changes with it. There are no registered users to email, so the version here is always the one that applies.
