# Frequently asked questions

> Short answers about apps, light and dark mode, the PC Builder, compare, reviews and promotions.

## Does Kelvin need any apps?

No. Everything in these docs works without an app. Three free or optional apps add to it:

* **Search & Discovery** (Shopify, free): the filters on collection and search pages, and the frequently bought together products.
* **A reviews app**, if you want star ratings written for you: cards and product pages read the `reviews.rating` and `reviews.rating_count` metafields such an app writes. Kelvin's own [reviews with Verified purchase](https://docs.kwebby.com/kelvin/guides/product-reviews.md) need no app.
* **A subscriptions app**, only to charge a monthly [Care+ plan](https://docs.kwebby.com/kelvin/guides/care-plus-protection-plans.md) every month at checkout.

## Can I make dark mode the default?

Yes. In **Theme settings → Colors**, set **Default color mode** to Dark, Light or Auto (follows the visitor's device). Visitors can still switch with the monitor in the utility bar. Turn **Show the color mode switch** off to keep everyone on the default: with the switch hidden, choices visitors made earlier are ignored too. See [Light and dark mode](https://docs.kwebby.com/kelvin/guides/light-and-dark-mode.md).

## Why is there no Auto button on the switch?

The switch is a single monitor: screen on is light, powered off is dark. When a visitor switches back to the mode your default would show, Kelvin forgets their choice, so the store follows your default again, and the device's setting when the default is Auto.

## Can I set dark-mode colors myself?

Yes. Every color scheme in **Theme settings → Colors** has a light palette and a dark palette, side by side. Change both when you change your brand colors. There is also a **Logo for dark mode** in **Theme settings → Logo**.

## Does the PC Builder or compare send data anywhere?

No. The current build, saved builds and the compare list are kept in the shopper's own browser. Nothing goes to an outside service. A build reaches you only when the shopper adds it to the cart and checks out.

## How many products can shoppers compare?

Two to four, set in **Theme settings → Compare → Products to compare at once** (4 on install). See [Compare](https://docs.kwebby.com/kelvin/guides/compare.md).

## Where do the specs on product cards come from?

From product metafields in the namespace `specs`, listed in **Theme settings → Product cards → Spec rows**. See [Spec rows](https://docs.kwebby.com/kelvin/guides/spec-rows.md).

## Are the countdowns and stock numbers real?

Yes. A countdown needs the real end time of your offer and removes itself when it ends; it never restarts. The low stock line reads your real inventory. See [Deal countdowns](https://docs.kwebby.com/kelvin/guides/deal-countdowns.md) and [Badges and pre-order](https://docs.kwebby.com/kelvin/guides/badges-and-pre-order.md).

## Can shoppers save products to a wishlist?

Kelvin has no wishlist, as Shopify's theme rules leave that to apps. Shoppers can keep up to four products in the compare tray and save PC builds on their device.

## Does Kelvin support B2B and wholesale?

Yes. The [Quick order list](https://docs.kwebby.com/kelvin/sections/quick-order-list.md) shows quantity rules and price breaks from your B2B catalogs. See [Quick order and B2B](https://docs.kwebby.com/kelvin/guides/quick-order-and-b2b.md).

## Which languages are included?

English, French, German, Italian and Spanish, plus right-to-left layouts for languages such as Arabic and Hebrew. See [Languages and right-to-left](https://docs.kwebby.com/kelvin/guides/languages-and-right-to-left.md).
