Good day to you!
Well, there are also other details the gameprovider, or better say, even the casino, may track, such as device, IP, and other settings saved via cookies.
Technically, I would say you gain no advantage over the casinos. Mainly also because the martingale does not work in the long run, according to our findings.
"The Martingale strategy is in many ways similar to betting on a strong favorite in a football match. The probability of losing one bet is not very likely, but you have to repeat it many times and wager a lot of money to achieve substantial profits. You will probably manage to be in the green at first, but sooner or later, the favorite will lose and your bankroll will be gone. Similar progressions happen with the Martingale strategy."

But everyone has his own style, and if you like it this way, I wish you best of luck, of course!
I hope you won't face any issues regarding the "strategy." though. As previously mentioned, certain casinos may aggressively pursue the closure of a player's account if they suspect that the player is engaging in unusual behavior.
That does not, however, imply that the player is abusing anything, in my opinion.
