Personalize Data For Users in Free Plan

Hello Glide Members!
I am in the process of making a glide PWA for my local Church’s Choir. I would like to personalize Data however, the free plan only allows us to have 10 signed in users. Due to these reasons, I have allowed only Choir Officials to sign in while the other 60 choir members are not signed in. Is there any way to differentiate different choir members in the database to unofficially personalize Data in the free plan. I am only a kid so I can’t really afford to upgrade plans. I did try to use device information to personalize the data, but when users have the same phone brand and model, this workaround doesn’t work. Anyone with ideas feel free to reach out! :smiley:
