Dexwell considering this - also for others who are interested, this is is a proposed description of the feature:
Feature Description:
An existing Kagi user, paying or not, known as the referring user invites a new user via:
- A referral link
- A direct email
If the new user signs up for the Kagi Premium tier then:
- The referring user is awarded a single referral bonus.
- The new user will be awarded a referred bonus.
The referral bonus is one free month of Kagi Premium - the referring user must already be a premium user.
The referred bonus is one free month of Kagi Premium after 3 months of paid premium usage (4th month free).
The referral bonus stacks and are burned down until the referring user has run out of referral bonuses.
Once a referring user no longer has referring bonuses stacked up their card will be charged as usual.
