Minha Carteira de Trabalho Digital está no aplicativo.

Because minha has to agree with carteira, and carteira is a feminine singular noun.

• meu = my for a masculine singular noun
• minha = my for a feminine singular noun

Examples:

• meu aplicativo = my app
• minha carteira = my wallet / my work card

It is the official Brazilian Digital Work Card, a government document/app-based record related to employment.

Literally:

• carteira = card, booklet, wallet, document holder
• de trabalho = of work / for work
• digital = digital

As a full expression, Carteira de Trabalho Digital is best understood as the name of a specific official document/service, not just a random combination of words.

Because this is being treated like the official name of a document or service.

In ordinary Portuguese, you usually do not capitalize common nouns the way English often does. But official names, app names, program names, or document names may appear capitalized, especially in government or institutional contexts.

So here capitalization signals:

• this is likely a specific official thing
• not just any generic digital work card

Because está is used for location or temporary state, while é is used more for identity, definition, or essential characteristics.

Here, the meaning is that the digital work card is in / is on the app, so location is the key idea.

• está no aplicativo = it is in/on the app
• é um aplicativo = it is an app

So está is the correct choice.

No is a contraction of:

• em = in / on / at
• o = the

So:

• no = in the / on the

Here:

• está no aplicativo = is in the app / is on the app

This contraction is extremely common in Portuguese.

Other examples:

• na = em + a
• nos = em + os
• nas = em + as

Because aplicativo is a masculine noun.

So the article is:

• o aplicativo = the app

And:

• em + o = no

If the noun were feminine, you would use na instead.

Examples:

• no celular = on the phone
• na conta = in the account

Yes. In Brazilian Portuguese, aplicativo is the standard word for app.

In everyday speech, many Brazilians also say app, especially in tech contexts, but aplicativo is very common and sounds fully natural.

So:

• no aplicativo = in the app / on the app

Yes. Carteira can mean several things depending on context, including:

• wallet
• card holder
• ID/work document
• even school desk in some contexts

In this sentence, the phrase Carteira de Trabalho Digital clearly refers to the official work document, not a wallet.

Context is what tells you the meaning.

Examples:

• Minha carteira está na bolsa. = My wallet is in my bag.
• Minha Carteira de Trabalho Digital está no aplicativo. = My Digital Work Card is in the app.

De often connects nouns in Portuguese, similar to of in English.

So:

• Carteira de Trabalho = Work Card / Card of Work

Even when English would prefer a noun used like an adjective, Portuguese often uses de + noun instead.

More examples:

• cartão de crédito = credit card
• sapato de couro = leather shoe
• mercado de trabalho = job market

Yes, that is grammatically correct.

In Brazilian Portuguese, possessives often appear with an article:

• a minha
• o meu
• as minhas
• os meus

So both are possible:

• Minha Carteira de Trabalho Digital está no aplicativo.
• A minha Carteira de Trabalho Digital está no aplicativo.

The version without the article can sound a bit more direct or formal in some contexts, which fits app or official language well.

Both can work as translations, depending on the kind of English being used.

Portuguese uses em / no / na in many cases where English might choose:

• in
• on
• sometimes even at

So está no aplicativo can correspond naturally to:

• It’s in the app
• It’s on the app

If the meaning is that the document is available through the app, English speakers often say in the app or on the app depending on personal preference and dialect.

A simple approximate pronunciation for an English speaker is:

MEE-nya kar-TAY-ra djee tra-BA-lyoo jee-jee-TAUW es-TAH noo a-plee-kah-CHEE-voo

A few notes:

• minha has a ny sound, like in canyon
• trabalho has lh, which sounds like a palatal ly
• digital in Brazilian Portuguese often sounds closer to jee-jee-TAUW
• está has stress on the last syllable: -tá
• aplicativo has stress on -ti-: a-pli-ca-TI-vo

The accent in está shows the stressed syllable and helps distinguish pronunciation.

• está = is
• stress falls on the last syllable: es-TÁ

Accent marks in Portuguese are important because they often tell you:

• where the stress goes
• sometimes how the vowel sounds
• sometimes they distinguish words that would otherwise look similar

It sounds neutral to formal, especially because it refers to an official document and uses standard wording.

Nothing in it is slangy or unusually casual. It would fit well in:

• an app interface
• a government website
• customer support language
• an informational message

Yes, but the original order is the most natural and straightforward.

Original:

• Minha Carteira de Trabalho Digital está no aplicativo.

Possible variations:

• A minha Carteira de Trabalho Digital está no aplicativo.
• No aplicativo está minha Carteira de Trabalho Digital. — grammatical, but less natural in everyday use unless you want emphasis

Portuguese allows some flexibility, but the original sentence is the best basic model for learners.

Because digital is describing the whole expression Carteira de Trabalho.

So the structure is roughly:

• [Carteira de Trabalho] Digital
• [Work Card] Digital

Portuguese adjectives often come after the noun they describe. Here, digital comes after the full noun phrase, which is natural in Portuguese naming style.

If you translated the structure too literally into English, it might look odd, but in Portuguese it works normally.

It specifically refers to the digital version because of the word Digital.

Without that word, Carteira de Trabalho could refer to the traditional work document more generally. With Digital, it clearly points to the app-based or electronic version.

So Digital is doing important work here: it tells you this is not the physical booklet/card.
