Yes, Affinity really is free. You can use every tool in the Pixel, Vector, and Layout studios, plus all of the customization and export features, as much as you want, with no restrictions or payment needed. If you’re on a Canva premium plan, you’ll also be able to unlock Canva’s powerful AI tools within Affinity.
When created a Canva account for Affinity 3, the setting “train AI using information about your general usage which includes fonts, colours, search queries and instructions you input. This does NOT include any of your uploaded images, videos, or designs” was on, “Allow your content to improve AI” was off.
For now it’s configurable at https://www.canva.com/account/privacy-preferences and I think they’ll have a hard landing on the face if they ever change it.
