OTO operates in markets that read in two directions and write in three languages. Localization is not a translation layer bolted on top — it runs from the dashboard a picker uses to the SMS a customer receives. ## Two different questions “What language is this in” has two answers, and confusing them is the usual source of trouble. | Audience | Who decides | | - | - | | **Your team**, working in the dashboard and the apps | Each person, for themselves. A warehouse manager in Riyadh and an operations lead in Istanbul can work in different languages on the same account. | | **Your customers**, reading a message or a tracking page | You, per message, when you author the content. See [Customer Notification](https://docs.tryoto.com/modules/customer-notification/overview.md). | > [!TIP] > > **Your interface language is not your customer's** > > Switching your own dashboard to English does not switch what the customer receives, and it should not. A team can work in whatever language suits it while every customer still reads their own. > > The practical consequence: if a customer reports a message reading oddly, changing your own settings will not reproduce it. Look at the content itself, in [Customer Notification](https://docs.tryoto.com/modules/customer-notification/overview.md), on the language tab they actually received. ## Interface languages The dashboard and the mobile apps are available in **English**, **Arabic** and **Turkish**. Arabic runs the interface **right-to-left** throughout — navigation, tables, forms and the apps — rather than translating the words and leaving the layout facing the other way. > [!NOTE] > > **Right-to-left is a layout problem, not a translation problem** > > Translated strings in a left-to-right layout is the common half-measure, and Arabic-speaking teams recognize it immediately: the text is right but everything is in the wrong place. > > Full RTL means the whole interface mirrors. It is the difference between software that has been translated and software that was built for the market. ## Country, currency, timezone and date format Each person sets their own regional preferences at **Settings → My Profile → Country and Region**. | Field | Behavior | | - | - | | **Country** | Detected and fixed — it anchors the rest, so it is not edited by hand. | | **Currency** | Follows from the country and is not separately editable. An account in the Kingdom reports in SAR. | | **Timezone** | Selectable. This is the one that matters most, and the one most often left wrong. | | **Date Format** | Selectable, e.g. `DD/MM/YYYY`. | > [!WARNING] > > **Check the timezone before you trust a report** > > Timezone decides where a day starts, which decides which day an order counts in, which decides whether a [preparation SLA](https://docs.tryoto.com/modules/hubs-management/overview.md) was met. > > A person whose timezone is set to the wrong city sees the same data as everyone else and draws different conclusions from it — and nothing on screen indicates a mismatch. It is worth checking on every account at setup, particularly for staff who joined from another market. ## What reaches the customer | | | | - | - | | **Messages** | SMS, email and WhatsApp content is authored per language, on its own tab. See [SMS](https://docs.tryoto.com/modules/customer-notification/sms.md), [Email](https://docs.tryoto.com/modules/customer-notification/email.md) and [WhatsApp](https://docs.tryoto.com/modules/customer-notification/whatsapp.md). | | **Branded pages** | Tracking and return pages carry their own language tabs, so the page matches the message that led to it. See [Branded pages](https://docs.tryoto.com/modules/customer-notification/branded-pages.md). | | **Order statuses** | Status descriptions are maintained in each supported language, so a tracking page reads naturally rather than showing an English status inside an Arabic page. | | **Documents** | The [carrier pickup list](https://docs.tryoto.com/modules/shipping-management/shipping-and-tracking.md) carries a language selector, so the manifest a driver signs is in the language they read. | ## Related * [Customer Notification](https://docs.tryoto.com/modules/customer-notification/overview.md) — where customer-facing language is set. * [Users, roles & permissions](https://docs.tryoto.com/platform/users-roles-and-permissions.md) — the profile these settings live on. * [Hubs Management](https://docs.tryoto.com/modules/hubs-management/overview.md) — working hours, which interact with timezone. ## Related topics - [Warehouse picking methods and waves](https://docs.tryoto.com/modules/warehouse-management/picking-methods.md) - [Last-mile delivery in OTO FLEX](https://docs.tryoto.com/modules/oto-flex/delivery.md) - [Product catalog and SKU configuration](https://docs.tryoto.com/modules/inventory-management/product-configuration.md) This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
