LANGUMU — TERMS AND CONDITIONS
Last updated: 2 June 2026
Please read these Terms and Conditions carefully before accessing or using the Langumu Service.
================================================================================
1. INTERPRETATION AND DEFINITIONS
================================================================================
1.1 Interpretation
Capitalised terms have the meanings given in this Section or where otherwise
defined in these Terms. Definitions apply regardless of whether terms appear
in the singular or plural.
1.2 Definitions
"Company," "We," "Us," or "Our" means Langumu, operated by Theorie Best
(KvK no. 42014778), registered in the Netherlands, reachable at
[CONTACT EMAIL — TO BE ADDED].
"Service" means the Langumu website at langumu.com, including all related
features, practice tools, AI-powered content, study materials, and any
associated applications.
"User Content" means any text, answers, written exercises, or other content
You submit through the Service.
"Access Package" means a one-time purchase granting access to premium features
of the Service for a fixed period, subject to the usage limits described
on the purchase page.
"AI-Powered Feature" means any feature of the Service that generates or
processes content using artificial intelligence, including AI-generated
practice questions, writing feedback, and explanations.
"Digital Content" means data produced and supplied in digital form, including
the personalised practice questions, feedback, and explanations generated for
You through AI-Powered Features.
"You" means the individual accessing or using the Service.
================================================================================
2. AGREEMENT TO TERMS
================================================================================
By accessing or using the Service, You confirm that You have read, understood,
and agree to be bound by these Terms and our Privacy Policy. If You do not
agree, You must stop using the Service immediately.
================================================================================
3. ELIGIBILITY
================================================================================
You must be at least 16 years old to use the Service. This age requirement
reflects the General Data Protection Regulation (GDPR), which sets 16 as the
minimum age for digital consent in the Netherlands.
If You are under 18, You may only use the Service with the consent and
supervision of a parent or legal guardian.
You confirm that You meet these requirements when You register. We may take
reasonable steps to verify your age and may suspend or close accounts where
the requirement is not met.
================================================================================
4. NATURE OF THE SERVICE — IMPORTANT DISCLAIMER
================================================================================
Langumu is an independent study platform. We are not affiliated with, endorsed
by, or in any way connected to DUO (Dienst Uitvoering Onderwijs), the Dutch
government, or any official examination body.
The practice questions and study materials provided by Langumu are:
- Independently created, comprising AI-generated content and human-written
or human-edited material
- Inspired by the format and topics of the inburgeringsexamen
- Not copies of official exam questions
- Not guaranteed to appear on any official examination
Langumu does not guarantee that use of the Service will result in passing any
official examination. Results depend entirely on the individual effort and
preparation of each user.
================================================================================
5. CONTENT — AI-GENERATED AND HUMAN-EDITED
================================================================================
The practice questions, explanations, feedback, and study materials on Langumu
are created through a combination of artificial intelligence and human
authorship. Our editorial process involves human review, editing, and — in
many cases — original writing by our team, applied on top of any AI-generated
output. As a result:
- Some content is wholly written by human authors; some is AI-generated and
subsequently reviewed and edited by a human; and some is produced by a
combination of both methods.
- Regardless of the production method, all published content has been
subject to human oversight before being made available on the Service.
- Because a human editorial contribution is applied to every piece of
content, the Service as a whole — and each individual item of content —
is protected by copyright and other applicable intellectual-property rights
(see Section 9).
- AI-generated elements may contain errors, inaccuracies, or outdated
information, and You should verify important information through official
sources such as the DUO website (duo.nl).
- AI explanations are educational aids, not authoritative legal or official
guidance.
- We make no warranty that any content — whether AI-generated or
human-written — is complete or error-free.
AI-Powered Features are a study aid and are not a substitute for official
preparation materials or guidance from DUO.
================================================================================
6. USER CONTENT
================================================================================
By submitting User Content (such as written exercises), You represent that You
have the right to submit it and that it does not violate any applicable law or
third-party rights.
You grant Us a non-exclusive, worldwide, royalty-free licence to host, store,
process, and analyse Your User Content for the purpose of providing the
Service to You — for example, to generate feedback on your exercises.
Where We use User Content to maintain or improve the Service, including
improving AI models, We do so using aggregated, anonymised, or pseudonymised
data wherever reasonably possible. Any personal data contained in User Content
is processed in accordance with the GDPR and our Privacy Policy, and You may
exercise your data-subject rights (including objection and erasure) as
described there.
To provide AI-Powered Features, User Content may be processed by trusted
third-party AI service providers acting on our behalf, which may be located
outside the European Economic Area (EEA). Where this occurs, We rely on
appropriate safeguards, such as the European Commission's Standard Contractual
Clauses. Our current service providers are listed in our Privacy Policy.
You agree not to submit content that is unlawful, offensive, harmful, or that
infringes the rights of others.
================================================================================
7. PROHIBITED USES
================================================================================
You may not:
- Attempt to reverse engineer, copy, scrape, or reproduce the Service or
its content
- Use the Service for any commercial purpose without prior written consent
- Circumvent any technical or security measures
- Share account credentials or allow others to access your account
- Submit false information during registration
- Use the Service in any way that violates Dutch or EU law
================================================================================
8. ACCESS PACKAGES, BILLING, AND REFUNDS
================================================================================
8.1 Free tier and Access Packages
Langumu offers a free tier and the following paid Access Packages:
- 1 Week Access (7 days) — EUR 14.90
- 1 Month Access (30 days) — EUR 24.90
- 2 Month Access (60 days) — EUR 39.90
Each Access Package is a one-time purchase. There is no automatic renewal and
no recurring charge. You will not be charged again unless You choose to buy a
new package.
AI-Powered Features within each Access Package are subject to usage limits.
The applicable limits for each package are displayed on the purchase page
before You proceed to payment.
8.2 Prices and payment
Current prices are shown on the purchase page before You proceed to payment. Payments are processed
securely by Stripe; by purchasing, You also agree to Stripe's terms of
service. We may change prices or usage limits at any time, but changes do not
affect a package You have already bought.
8.3 What You are buying
The premium features of the Service — including AI-generated practice
questions, writing feedback, and explanations — are personalised Digital
Content generated for You on demand. Supply of this Digital Content begins the
first time You use any AI-Powered Feature after purchase. Access to a package
ends at the close of the purchased period.
8.4 Right of withdrawal (14 days)
As a consumer in the EU, You have the right to withdraw from your purchase
within 14 days, without giving a reason, unless You have lost that right under
clause 8.5.
8.5 Consent to immediate supply and loss of the right of withdrawal
Because the premium features are supplied immediately and on demand, We ask
You at checkout — by a separate box that You must actively tick before payment
— to confirm that:
(a) You expressly request that supply of the Digital Content begins
immediately, before the end of the 14-day withdrawal period; and
(b) You acknowledge that, once supply begins, You lose your right of
withdrawal.
We confirm this to You by email after your purchase. Accordingly:
- If You have not yet used any AI-Powered Feature, supply has not begun,
and You may withdraw within 14 days for a full refund.
- Once You use any AI-Powered Feature, supply of the personalised Digital
Content has begun with your prior express consent, and your right of
withdrawal no longer applies. No refund is due for the remainder of the
access period.
We use artificial intelligence to generate this content, and each interaction
creates a real, immediate cost to Us that cannot be recovered. This is why
supply is treated as beginning at first use.
8.6 Your statutory rights are not affected
Clause 8.5 concerns only the 14-day right of withdrawal. It does NOT affect
your mandatory rights under EU and Dutch law where Digital Content or a
digital service is defective, fails to work, or does not match its
description. If that happens, You remain entitled to the remedies the law
provides — such as bringing the content into conformity, a price reduction,
or a refund — regardless of whether You have used an AI-Powered Feature.
8.7 How to request a refund
Where You are entitled to a refund (for example, because You have not used
any AI-Powered Feature, or because clause 8.6 applies), contact us at
[CONTACT EMAIL — TO BE ADDED] within the applicable period. Eligible refunds are
returned to your original payment method.
================================================================================
9. INTELLECTUAL PROPERTY
================================================================================
All content on the Service — including but not limited to questions, study
materials, AI explanations, design, and code — is the exclusive property of
Langumu or its licensors.
Where content on the Service has been generated in whole or in part using
artificial intelligence, a human author has in every case reviewed, edited,
selected, arranged, or otherwise contributed original creative or intellectual
effort to that content before it is published. This human contribution
constitutes original authorship for the purposes of copyright law, and the
resulting works are protected accordingly.
You may not copy, reproduce, distribute, sell, or create derivative works from
any part of the Service without prior written permission.
The name "inburgeringsexamen" and related exam names are official government
terminology and are used purely for descriptive purposes. Langumu makes no
claim of ownership over these terms.
================================================================================
10. PRIVACY AND GDPR
================================================================================
Langumu processes personal data in accordance with the GDPR and Dutch privacy
law. Please refer to our Privacy Policy at langumu.com/privacy for full
details on what data we collect, why, and your rights as a data subject.
Some processing — including AI-Powered Features and payment handling — involves
trusted third-party service providers (such as our AI provider and Stripe),
some of which may be located outside the EEA under appropriate safeguards.
These providers are described in our Privacy Policy.
Your rights under the GDPR include:
- The right to access your personal data
- The right to correction or deletion
- The right to object to processing
- The right to data portability
To exercise any of these rights, contact us at [CONTACT EMAIL — TO BE ADDED].
================================================================================
11. SERVICE AVAILABILITY AND CHANGES
================================================================================
We may add, change, suspend, or remove features of the Service, and We may
carry out maintenance that temporarily interrupts access. We will try to limit
disruption to paying users.
If We permanently discontinue the Service, or permanently remove a paid
feature that was a material part of an Access Package You have purchased, We
will refund the unused, proportionate part of that package. This does not
apply where your access is terminated because You breached these Terms
(see Section 12).
================================================================================
12. TERMINATION
================================================================================
We may suspend or terminate Your access at any time if You violate these Terms
or engage in conduct that we reasonably believe is harmful to the Service or
other users. Upon termination, all rights granted to You cease immediately.
If Your access is terminated due to a violation of these Terms, no refund will
be issued for any unused portion of a purchased Access Package.
You may delete your account at any time by contacting us or using the account
settings page.
================================================================================
13. DISCLAIMER OF WARRANTIES
================================================================================
The Service is provided "as is" and "as available" without warranties of any
kind, whether express or implied. To the fullest extent permitted by Dutch and
EU law, Langumu disclaims all warranties including fitness for a particular
purpose, accuracy, and uninterrupted availability.
We do not warrant that the Service will be error-free or that practice content
reflects the exact content of any official examination.
Nothing in this Section affects the mandatory legal guarantees that apply to
consumers under EU and Dutch law (see clause 8.6).
================================================================================
14. LIMITATION OF LIABILITY
================================================================================
To the maximum extent permitted by applicable law, Langumu's total liability
to You for any claims arising from use of the Service shall not exceed the
greater of (a) the total amount You paid to Langumu in the 12 months before
the claim arose, or (b) EUR 50.
Langumu is not liable for:
- Failure to pass any official examination
- Indirect, incidental, or consequential damages
- Loss of data or interruption of service
- The accuracy of AI-generated content
Nothing in these Terms limits liability for death, personal injury, or fraud
caused by our negligence, or any other liability that cannot be excluded under
Dutch mandatory law.
================================================================================
15. GOVERNING LAW AND DISPUTES
================================================================================
These Terms are governed by the laws of the Netherlands.
If You are a consumer, You keep the protection of the mandatory consumer-law
provisions of the country where You live, and nothing in these Terms takes
those protections away.
Disputes may be brought before the competent court in the Netherlands. If You
are a consumer in the EU, You may also bring proceedings in the courts of the
country where You live, and We will bring proceedings against You only in that
country.
If You have a complaint, please contact us first at [CONTACT EMAIL — TO BE ADDED] so We
can try to resolve it directly. Depending on your country, You may also be
able to refer the dispute to a competent alternative dispute resolution (ADR)
body or your national consumer authority. Information and guidance for EU
consumers is available through the European Commission's "Your Europe" portal.
================================================================================
16. FORCE MAJEURE
================================================================================
We are not liable for any failure or delay in providing the Service caused by
events beyond our reasonable control, including outages of hosting, network,
payment, or AI service providers, cyber-attacks, power or internet failures,
or acts of government.
================================================================================
17. ASSIGNMENT
================================================================================
You may not transfer your rights or obligations under these Terms to anyone
else. We may transfer ours — for example, if We sell or reorganise the
business — provided this does not reduce your rights as a consumer. We will
notify You if this happens.
================================================================================
18. CHANGES TO THESE TERMS
================================================================================
We may update these Terms from time to time. When we make material changes, we
will notify You by email or by a prominent notice on the Service at least 14
days before the changes take effect.
Continued use of the Service after the effective date constitutes acceptance
of the updated Terms.
================================================================================
19. SEVERABILITY
================================================================================
If any provision of these Terms is found to be invalid or unenforceable under
applicable law, that provision will be modified to the minimum extent necessary
or severed, and the remaining provisions will continue in full force and effect.
================================================================================
20. ENTIRE AGREEMENT
================================================================================
These Terms, together with our Privacy Policy, form the entire agreement
between You and Us regarding the Service and replace any earlier agreements on
the same subject. If there is a conflict between these Terms and the Privacy
Policy on a data-protection matter, the Privacy Policy applies.
