Privacy Policy

The Truth—before the policy

Before going into the actual “policy” that we literally never read, let me give you some “Bluntly Honest Warnings about Anonymity or the So-called Anonymous Statistics”—applicable for not just my website, but consider this for any website on the Internet:

Although all statistics I save is technically “anonymous,” or so it is said by every other website. However, it is possible to connect multiple meta-data from internal or external sources, matching those time-stamps and other information it is possible to identify someone often quite easily. Example:

If you are just visiting this website, without logging in or without giving me any information, I still already know your public IP address, name of your Internet Service Provider, your neighbourhood or city level location, the time-stamp of your visit, the amount of time you spent on which page, details of the device you used, i.e: weather it is a phone or a computer, the model of the device, name and version of the browser/app, name and version of the operating system, your screen resolution or size (unless you are actively hiding your track by using some tool). And it has nothing to do with the cookies, it does not matter whether you allow them or block. This much information you are giving up literally the moment you click a link or visit “any website” you browse on the Internet, period.

In most cases these information are constantly collected and archived indefinitely. Now if I have any additional meta information about you, like the time you exactly browse my website, I would be able to match that time-stamp with my statistical record, and find out who you are and what you did here. One trick phone call to your ISP might also reveal your exact address. It is that easy!

(The actual) Privacy Policy


This website is single handedly created and managed by myself (Mohammad Tauheed), i.e: There is no team/party involved who may have access to the server and its content. I respect your privacy, and I handle your data with utmost security and confidentiality. I use standard cookies and/or sessions and certain third-party services to improve your experience of using the website (

Understanding ‘Cookies’

Consent to use of cookies

Cookies collect information about how visitors use the site, for instance which pages visitors go to most often, and if they get error messages from web pages. These cookies do not collect information which identifies a visitor, and I will not use cookies to collect personally identifiable information about you. All information is aggregated and therefore anonymous. By using the website you agree that I can place these types of cookies on your device.

Also, all third-party plugins may have different policies for anonymity.

2. Your public IP address with time-stamp is logged and kept on record. This also allows the system to obtain and record certain publicly available meta-information aggregated from your IP address, which may include your ‘city, neighbourhood or country-level’ location and basic information about your internet connection. This is a standard practice invariably applied at any website on the internet.

Your interactions with any third-party run embedded media (Example: embedded YouTube video, issue book, SoundCloud audio, Facebook post and video, Instagram post, Tweets, Flickr photos etc.) within website may have different terms and privacy policy set by the respective owners/operators of the embedded media or contents. Those policies may greatly vary from’s privacy policy. If you have an active “third-party cookie” blocking on your browser, you should be safe from these external cookies.

7. Your connection from your browser to server may be routed through a CDN (Content Distribution Network), i.e: CloudFlare. (Details in the following paragraphs).

8. Physical location and local laws: I am primarily based in Bangladesh.

Generally you are being served from the nearest CDN server. No matter where the contents are physically served from, I adhere to the local (Bangladeshi) laws of Information and Communication Technology for data protection, privacy, abuse and other statutory issues.
