Premium subscriptions are individual, and should only be used by one person. You can use your same account on all your personal devices if you have more than one.
If you're looking to share Tarteel with your loved ones, we recommend the Family Plan which allows you to have up to 5 individual Premium accounts on 1 subscription. This way, everyone's activity remains on their own Tarteel account and they get to use and experience Tarteel Premium at an unbeatable value.
