It is a personal website that I have created as a retirement hobby. I get to work on it sporadically when I am not busy doing chores and other activities. Much of the content is related to items that I collected in my packsacks during my teaching career. Occasionally I may add a few web pages based on something more contemporary that has happened in my life since I retired from teaching.
As far as I am concerned anyone lurking out there on the Internet may freely visit my website while remaining completely anonymous. I am not attempting to collect any personal information about the visitors to my website.
The only way I would know that you have visited my website is if you are one of the rare individuals who sends me an email message. Over the years I have received a few email messages from people thanking me for creating the website and explaining why they found it useful. I have received a few emails from people asking me a question related to the content of my website. I have received far too many emails from businesses trying to sell me something, especially their website creation services.
Hey this is my retirement hobby website! I want to create it myself. I am not interested in your sales pitch about how your staff or new robot could create a much better website than my shoddy efforts.
A cookie file might be saved on your computer
I have created one cookie for some of my web pages. It is a functional cookie and not a tracking cookie. On my web pages with large photos you may see the following line above the first large photo.
Zoom photos: 40% 50% 60% 70% 80% 90% 100% 120% 140% 160% 180% 200% of screen width.
This is a multiple choice question. You have an opportunity to mouse click on one of the percentages. Your web browser software will save the percentage you selected as a small file on your computer. This small file is called a cookie. The programming code of my web page will then read the percentage in the small cookie file and display all of the large photos on the web page zoomed to that percentage of your screen width. If you visit other web pages on my website with large photos then they will also be displayed zoomed to the percentage of your screen width that is saved in the cookie file.
You can change your answer as often as you like by selecting other percentages. The contents of the cookie file will be changed each time to the most recent percentage you have selected. All of the large photos will adjust their size accordingly.
In a few days after you visit my website the cookie file will expire and be automatically deleted by your web browser software. You can delete the cookie before then as part of the process of deleting your web browser's history and cache files.
Advertisements from Google's Adsense program
Many of the web pages of my website contain advertisements provided by Google's Adsense program. I just insert a few lines of programming code provided by Google into each of my web pages and then Google's computers decide which advertisements to display. A vast network of advertising agencies and businesses provide the advertisements.
Here is a link to a web page that Google has created to explain how Google uses the information it receives when you visit a website such as mine to display the advertisements you see from its Adsense program.
