Converting Linea from a subscription to lifetime purchase
Before you can change from a recurring subscription payment to a single lifetime purchase, you must first cancel your existing subscription (or allow your free trial period to expire).
Here are the steps to follow to cancel your existing Linea Sketch subscription:
• Open iOS Settings > Tap your name/account at the very top of the screen
• Tap Subscriptions > Linea Sketch > Canel Linea Sketch (Monthly or Yearly)
Next you must wait between 48 and 72 hours for the subscription cancellation to take effect.
Once the cancellation finishes processing you should see the Lifetime Purchase option appear once again in Linea's In-app Settings > Linea Premium Status. Purchasing the one-time option enables all Premium features for the life of the product and is a great way to avoid recurring payments.
