I don't track my gambling activities either, because I don't gamble that much... I mostly visit sports betting sites unless I feel like having some fun outside of sports betting.
You can find everything you need to monitor your gambling on the site itself, unless you want to track extra details like the time you spend on them. I'm not sure, but there should be some external tools to do that, or you could simply create one (if you have the knowledge) to track the time you spend on a specific URL.
Hi promise, not keeping records of your bets because you do not gamble much? Fair, but in the future you may want to improve your game sense, and software such as Toggl Track, RescueTime or ActivityWatch can auto-log how long you spend on those betting pages and you don’t need to know dev skills for that. Heck, you can even get some crazy stats by URL just through a Chrome extension like Web Activity. Track smart, not blind, just sayin, bruh.
