Why a Grammarly Charge Can Look Unknown
1. The charge belongs to a different Grammarly account
Many users have more than one Grammarly login.
What this means: The charge is real, but tied to an account you forgot about.
2. The charge is a normal renewal you did not recognize
If you have not looked at Grammarly billing recently, a scheduled renewal can feel unexpected.
What this means: The charge may be valid, but surprising.
3. The payment method was used by another person
A shared card or shared device can create confusion.
What this means: The charge may still be legitimate from Grammarly’s side, but unauthorized from yours.
