One-Time Lifetime Payment Option for Narwhal2 App

Dear Narwhal Team, I hope this message finds you well. I am a user of the Narwhal2 app and appreciate the excellent experience it provides. I would like to suggest the implementation of a one-time lifetime payment option for users who prefer not to commit to a subscription model. By introducing this payment choice, you can cater to a broader audience, including those who prefer a single upfront payment rather than a recurring subscription. This flexibility could potentially attract more users and enhance the overall user satisfaction. Thank you for considering this feature request. I look forward to the continuous improvement of Narwhal2.
