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 want to share Tarteel with loved ones, consider the Family Plan which allows up to 5 individual Premium accounts on one subscription at great value. Learn more here: Family Plan.
Already paying for Premium? Go to tarteel.ai/pricing and click "Switch to Family Plan". If you pay annually, you get a credit for the time you have not used. Read How do I switch from Premium to the Family Plan?.
