Enter the key from your Kavio Labs account. Without a key the theme runs a 14-day trial. After the trial the store keeps working and this page shows a reminder. The links on the tab lead to your licences, this documentation and support.
No. It installs as a theme extension, adds its own templates and events, and ships no OCMOD. Uninstalling removes its events and settings and switches the store back to the stock theme.
OpenCart keeps stock per option value, not per combination. A coat with a Colour option and a Size option cannot know that "navy, size M" is sold out. With one product per colour and a Size option, every size of every colour has its own stock. The Style attribute links the colourways: cards show all colours and the product page switches between them. A Colour option still works too, if you prefer it.
The quick-add bar does not appear on some cards. It appears when the size is the only required option of the product, the product is in stock, and prices are visible. Products with more required options, such as engraving text, open their product page instead.
Yes. Atelier crops them to 3:4 on cards and in the gallery; the first product image is shown uncropped. For the best result, use 3:4 portraits at 900 x 1200.
They are Atelier's own illustrations, coloured by the preset. Set your own images on the Home page tab to replace them.
No. OpenCart has no guest newsletter list. The band links to the newsletter page for signed-in customers and to registration for guests, where the newsletter box is part of the form.
No. The fonts are self-hosted and preloaded, there is one stylesheet layer and one small script, and images load lazily below the fold. Atelier adds no tracking and makes no external requests.
Nothing visible to shoppers. The store keeps the theme, and the settings page shows a reminder. The licence covers updates and support for 12 months.
