We are constantly working to improve our software for both existing and new users. Like all app developers, we have to balance building a sustainable future for our software with the needs of our customers. By letting our customers buy only the licences they want, we think our licensing model is the best way of achieving this.
Were we to provide a single licence covering all operating systems and major updates, we would have to either charge significantly more or move to a subscription model. We prefer the “pay upfront for what you need” approach because there are so many subscription services out there now that we don’t want to add yet another monthly bill to your expenses. We also don’t want you to have to worry about being locked out of your writing because you missed a subscription payment.
