Duolingo was built with a singular goal: to bring high-quality education to everyone
on the planet by harnessing the power of technology. And while we started with
language learning, Duolingo has become so much more than that: we've developed
an on-demand English proficiency test, we've produced award-winning podcasts,
we've launched Duolingo ABC to help kids learn to read, and we've done all of this by
creating content that's both entertaining and effective.
Since our launch 10 years ago, we've continued to test and evaluate our teaching and
assessment methods to ensure our courses are free, fun, and effective—highlighted
by a recent study showing how learning French or Spanish on Duolingo leads to
comparable outcomes as learning at a U.S. university.
Our team is made up of some of the smartest minds in education and technology, and
together, we have revolutionized many aspects of online learning. Here are just a few
of the most exciting educational and technological advancements we've made in the
last 10 years!
|English - Espafiol - Deutsch - Portugués
Desarrollamos Duolingo con un Unico objetivo: llevar la educacién de alto nivel a
todas las personas en el mundo con el poder de la tecnologia. Si bien empezamos
con el aprendizaje de idiomas, Duolingo se ha convertido en mucho mas que eso:
desarrollamos un examen de dominio de inglés bajo demanda, hemos creado
podcasts que han sido galardonados y lanzamos Duolingo ABC para ayudar a los
ninos a aprender a leer. Logramos todo esto al crear contenido que no solo es
divertido, sino también efectivo.
Desde nuestro lanzamiento hace 10 anos, probamos y evaluamos constantemente
nuestros métodos de ensenanza y evaluacion para asegurarnos de que nuestros
cursos son gratis, divertidos y efectivos (algo resaltado por un estudio reciente que
demostroé que alguien que aprende francés o espanol en Duolingo obtiene resultados
similares a alguien que estudié en una universidad de EE. UU.).
Nuestro equipo esta integrado por algunas de las mentes mas brillantes en la
educacion y tecnologia y, juntos, hemos revolucionado muchos aspectos del
aprendizaje en linea. jA continuacién hablaremos de solo algunos de los avances
educativos y tecnolégicos que logramos en los ultimos 10 anos!

In reply to Kirill Nikolaev - 2 years
I've successfully completed this week's
assignment. However, for recursive squares,
is "The 'main()' method must directly call the
public method 'drawSquare()".
[MainCallsAllPublicMethods]" really
necessary? As only the pattern has to be
drawn, isn't the program's logic to only call for
draw(n, x, y, len)? This, of course, does not
affect points in any way, shape, or form, but is
slightly frustrating :)

Great!

At Duolingo, we care about your personal data, so we have prepared this Privacy Policy to explain how we
collect, use and share it.
This Privacy Policy (“Privacy Policy”) details the personal data Duolingo, Inc. (“Duolingo”, “we", “us” or “our”)
receives about you, how we process it and your rights and obligations in relation to your personal data.
Duolingo, Inc., a company registered at 5900 Penn Ave, Second Floor, Pittsburgh, PA 15206, United States of
America is the data controller for the purposes of the General Data Protection Regulation ("GDPR") and any
relevant local legislation (“Data Protection Laws").
By using or accessing the Service, you agree to the terms of this Privacy Policy. Capitalized terms not defined
here have the meanings set forth in the terms and conditions (the “Terms and Conditions”), located at
www.duolingo.com/terms. We may update our Privacy Policy to reflect changes to our information practices. If
we do this and the changes are material, we will post a notice that we have made changes to this Privacy
Policy on the Website for at least 7 days before the changes are made, and we will indicate the date these
terms were last revised at the bottom of the Privacy Policy. Any revisions to this Privacy Policy will become
effective at the end of that 7 day period.
If you are an employee, worker or contractor of Duolingo, the information about how we handle your personal
information is available in the Duolingo internal knowledge base. With respect to employees based in Europe,

provide your email address you can unsubscribe any time by emailing literacy-feedback@duolingo.com or by
clicking the unsubscribe link in any Duolingo ABC emails. Your Duolingo ABC data is backed up into Apple’s
iCloud which allows you to synchronize and restore the data onto another Apple device.
6. Sharing your personal data with third parties
Duolingo shares your personal data only when it is necessary to offer the Service, legally required, or
permitted by you.
We will provide personal data to hosting providers such as Amazon Web Services, search engine providers
such as Google, analytics providers such as Crashlytics, and support providers such as ZenDesk.
These data processors help us bring you the Service. For example, we may share your information in order to
detect where or how you encountered a bug when using our mobile application. In connection with these
operations, our service providers will have access to personal data for a limited time. When we utilize service
providers for processing any personal data, we implement contractual protections limiting the use of that
personal data to the provision of services to Duolingo.
We will be required to access and disclose personal data in response to lawful requests, such as subpoenas or
court orders, or in compliance with applicable laws. Additionally, we will access and share account or other
personal data when we believe it is necessary to comply with law, to protect our interests or property, to
prevent fraud or other illegal activity perpetrated through the Service or using the Duolingo name, or to
prevent imminent harm. This will include accessing and sharing personal data with other companies, lawyers,
agents or government agencies.
Duolingo will share the complete and accurate results of Duolingo English Tests with such institutions,
including universities, potential employers, or other third parties, (collectively, “Score Recipients”) as specified
when you send your results after finishing a test or when you apply a coupon sponsored by the Score Recipient
before starting a test. These results will include your test score, a video of the interview section of your test,
and your written responses to certain parts of the test. We will also share your full name, date of birth, e-mail
address, and the photo you take of yourself. We will never share examination results with any party without
your approval, except that anonymized examination results will be used by Duolingo and its partners to
improve the examination and for research and analysis. We will not share your Testing ID with any Score
Recipients, except with your consent upon initiation of a dispute by a Score Recipient.
If the ownership of all or substantially all of the Duolingo business, or individual business units or assets
owned by Duolingo that are related to the Service, were to change, your personal data will be transferred to

MISSION APPROACH TEAM CAREERS RESEARCH PRESS CONTACT US

Our teaching approach

We believe that anyone can learn a language with Duolingo. Our free, bite-size lessons feel more like a game

than a textbook, and that's by design: Learning is easier when you're having fun.

But Duolingo isn't just a game. It's based on a methodology proven to foster long-term retention, and a

curriculum aligned to an international standard. Let's explore how language learning happens with Duolingo!
Real-life communication
Language is ultimately a communication tool. Duolingo takes a
functional approach by focusing on what learners actually want to do
with a language.

-

Lessons focus on a real-life goal — for instance, ordering at a
restaurant. Learners develop the vocabulary and grammar needed to
achieve that goal through lots of varied practice in reading, writing,
listening, and speaking.

and reading and listening comprehension — all valuable skills for real-
world language practice!
Continuous improvement
At Duolingo, we're committed to improvement. Test questions are \
embedded throughout our courses to measure how learners are
progressing — and to show where Duolingo can improve.
We use the results to develop new and better courses, expand our
universe of language-learning tools, update our materials as
languages evolve, and ensure we're continuing to offer the best
language education in the world. Like language, we never stand still. - L

Personalized education.
Everyone learns in different ways. For the first time in history, we can
analyze how millions of people learn at once to create the most effective
4 educational system possible and tailor it to each student.

Our ultimate goal is to give everyone access to a private tutor experience
through technology.

Making learning fun.

It's hard to stay motivated when learning online, so we made Duolingo so

fun that people would prefer picking up new skills over playing a game.

Along with commonly used phrases like ";Ddnde esta el bafo?" (Where
is the bathroom?), Duolingo learners also encounter sentences like “Tu
0so bebe cerveza" (Your bear drinks beer).
Why the quirky sentences? They're memorable and more fun to learn.
Our unexpected content also pushes learners to think carefully about
the language they're learning.
A balanced approach
Duolingo allows learners to discover patterns on their own without
5 needing to focus on language rules — the same way you learned your
{7 ding to f L l th l d
) ° first language as a child. This approach, called "implicit learning,” is
OO0 ideal for developing a strong foundational knowledge of a language
and its rules.
But explicit instruction is useful for some concepts. So Duolingo offers
both! In addition to lessons, learners can access Tips for explanations
on grammar, pronunciation, and helpful phrases.

Recursive Squares Checkstyle
I've successfully completed this week's
assignment. However, for recursive squares,
is "The 'main()' method must directly call the
public method 'drawSquare()'.
[MainCallsAllPublicMethods]" really
necessary? As only the pattern has to be
drawn, isn't the program's logic to only call for
draw(n, x, y, len)? This, of course, does not
affect points in any way, shape, or form, but is
slightly frustrating :)

In hiragana, each character represents a syllable. For example, 5L/ is
p,.....-..n-m.a simbal 14 mnaan~ amias Pan vian fia s ant kot B maaan~9
A word of part of a word that contains one vowel sound. For example, "cat" has one
syllable, but "banana" and "pineapple” have three.
Lnaraceern rronunciauon
su like in "super" (sometimes
El sounds like just "s" at the end of
a word)
L shi like in “she”

In hiragana, each character represents a syllable. For example, 5L/ is
pronounced ushi. It means cow. Can you figure out what 3’[; means?

¢ Back Recursive Squares Checkstyle @

Recursive Squares Checkstyle
I've successfully completed this week's
assignment. However, for recursive squares,
is "The 'main()' method must directly call the
public method 'drawSquare()'.
[MainCallsAllPublicMethods]" really
necessary? As only the pattern has to be
drawn, isn't the program's logic to only call for
draw(n, x, y, len)? This, of course, does not
affect points in any way, shape, or form, but is
slightly frustrating :)
