Hi Goronmon,<p>My name is Eva Schweber and I work for AgileBits, the folks who make 1Password.<p>While it is true that we think it is important for our potential customers to know that we may charge for a future version of 1Password, we have only done this once in the 9 years that 1Password has been available. And that was after a significant upgrade from 1Password 3 to 1Password 4 when we rewrote the entire app from scratch.<p>Customers who purchased 1Password 4 for iOS have received free upgrades (including Pro Features) to 1Password 5 and 1Password 6. The same is true for our 1Password 4 for Mac customers, who received 1Password 5 (our current version) for free.
