This Privacy Policy explains more specifically what information Nufisys SARL (together, “Nufisys,” ”Nufisys SARL”, “we” or “us”) collect and receive from End Users (“you”) through Nufisys' websites and applications, which we refer to collectively as “the Service.” The Service includes the following software offered by Nufisys SARL:

Please note, if you use any of the applications listed above, you are the End User of a Nufisys service account. You can find these and other defined terms used in this policy in our Glossary at the end of this page.


Although significant changes are rare, this policy may be amended as new features, technology, or legal requirements arise, so please check back from time to time. We'll notify you if we make a significant change and, where required, seek your consent.

What information does Nufisys collect and receive?

The Nufisys services are built around two main categories of applications:

1.       Nufisys language learning applications are built to help you learn new languages in a community. That means you can input, upload, or store text, images, and other data (e.g. voice) that you choose (collectively, “Content”) with other users of the application.

2.       Nufisys information sharing applications are built to share different type of useful information with other users of the applications. Examples of such information include service-providers and their location, real-time traffic information, neighborhood safety information etc.

Nufisys content is shared anonymously. This means, we do not expose the identity of the user who shared content to other users.

To provide the above service in an efficient and transparent manner we also collect and receive the following types of information:


Basic subscriber information. To share new entries with other users, we collect and receive basic information like your email address. 

Log data. When you use Nufisys Apps, we collect data to understand how you and others access and use the Service, as well as information about actions you take when using the Service (such as the act of creating or sharing an entry). This includes the use of cookies. This information helps us provide the Service to you, learn how the Service is used, and identify and suggest ways we can make the Service more useful to you.            

Location information. We collect the IP address you use to connect to the Service, and — if you choose to share it — your location information from a mobile device. This helps us localize the Service for you and, depending on your location settings, allows us to show you relevant content accessible from your account.

Device information. We collect information about the number and type of devices you use to connect to the Service, as well as information about the operating systems on those devices (e.g., iOS, Android, Windows) to ensure the Service works as expected for you. Learn more about information our applications collect from your device on our Data Usage page.

We also may link your subscriber information with data we receive from our partners and other third parties to help understand your needs and provide you with a better experience.  For example, if you create or log into a Nufisys App account using your Google Apps credentials via single sign-on, we will have access to certain information such as your name and email address as authorized in your Google Apps profile settings.

How do Nufisys Apps use my information?

We have specific rules for how and when we use the information we collect and receive. We describe these below.

What do Nufisys Apps do with my information?

We are committed to protecting the privacy of your information. Below, we describe the ways in which we use the information we collect and receive to provide, maintain, and improve the Service; to provide troubleshooting and customer support; to protect the Service for all our users; to contact you; and to administer Nufisys Apps accounts.

We use a number of technologies to help you get the most out of the Service. Our systems automatically analyze your data to power Nufisys Apps features and to continually improve the Service for you in a way that does not require anyone to look at your Content. This may include, for example:

Making sure you find what you're looking for when you search your account.

Showing you information most relevant to how you are or could be using the Service at a specific time or location.

Suggesting actions for you to take based on information you've stored.

Suggesting Nufisys service features or products to you that we think will help you get the most out of our Service.

To provide troubleshooting and customer support, our Customer Support team may need to access your information, such as your account email address and information about the Nufisys application you are using, subject to the protections described above. 

As part of our efforts to protect your account and the functionality of the Service, our systems may analyze the entries you share via your Nufisys App account to detect spam, malware, or other potential security concerns. If we determine that such material constitutes a Terms of Service or User Guidelines violation, we may block delivery of or unshare the problematic material, much like a spam filter works for your email inbox.

Learn more about steps you can take to protect your account, such as using strong passwords, two-step verification, and encryption.

In accordance with your communication preferences, we'll occasionally contact you to announce new products and features we build for you, share tips for using Nufisys App more efficiently, make special offers, and provide information about how Nufisys Apps work with products and services from our business partners.

Would someone at Nufisys ever view my Content?

By default, every content you share through Nufisys services can be viewed by all other users of the applications.

To help refine or improve the technology, we may review portions of your Content. For example, if a new feature suggests related entries that are relevant to your Content, we may give you an opportunity to provide us feedback on how well the feature is performing along with a sample of the Content in question, so we can make sure this feature provides appropriately tailored suggestions.

If we become aware of a potential violation of our Terms of Service or User Guidelines, we may suspend or close your account until the problematic material is removed.

To test and improve our product offerings for our users, we use aggregated data that does not contain any personal information, does not identify any person, and cannot be connected to any specific user. This policy is not intended to apply to such anonymized/de-identified data.

How do Nufisys Apps share or disclose my information?

Nufisys is not in the business of selling or renting your information. Here are instances when we may disclose your information — and then only the minimum information necessary:

Operate, develop, and improve the features and functionality of the Service

Communicate with you as described elsewhere in this policy

We do not share your information with any third parties for their own advertising purposes.

In the event of a merger, sale, or reorganization of all or part of our business, information covered by this policy may be transferred in connection with that deal. 

As described on our Cookie Information page, we contract with third-party advertising networks in order to deliver relevant Nufisys Apps advertisements to you across the Internet and to manage our communications with you. We do not use your Content for these purposes. In addition, we may share with partners or Service Providers a hashed identifier to serve you relevant Nufisys Apps ads when you visit partners' and providers' websites, applications or platforms. We may, for instance, participate in the Twitter Tailored Audience and Facebook Custom Audience services. To learn more about the privacy controls that Twitter and Facebook offer and honor for those respective services, please visit here for Twitter and here for Facebook. You may opt out of certain ad targeting and retargeting services by visiting the Digital Advertising Alliance's opt-out page, or the Network Advertising Initiative's opt-out page.

We also may share information about you with third parties whenever you consent to or direct such sharing. This includes, for example, if you connect your Nufisys Apps account with a third-party app in our App Center.

How does Nufisys respond to legal requests for my information?

We vigilantly protect the privacy of your account. We will not disclose your information to law enforcement or other governmental authorities unless we believe it is required to comply with warrants, court orders, subpoenas, or other lawful government requests. This may include responding to legal requests from jurisdictions outside of the United States where we have a good faith belief that the response is required by law in that jurisdiction, affects users in that jurisdiction, and is consistent with internationally recognized standards of due process.


We narrowly interpret all information requests, and we only disclose Content in your account that is specifically responsive to a government warrant or where you have provided your explicit consent. In accordance with our user notice policy, we will notify you if we believe we are compelled to comply with a third party's legal demand for your information, and we routinely push back on government orders to delay user notice that we view as overly broad. You can find more information in our current Transparency Report.


In addition, in rare cases, we may share your information as necessary to investigate or take action regarding illegal activities, suspected fraud, or potential threats against persons, property or the systems on which we operate the Service, or as otherwise necessary to comply with our legal obligations.


How can I manage my information stored in Nufisys Apps?

Consistent with our first law of data protection—your data is yours—in most cases, you can manage your information simply by logging into your account and editing your information directly within the Nufisys Apps service.


However, if you prefer, you can contact us at to ask us to provide access to, correct, update, or delete your personal information. Please note that we may ask you for proof of account ownership and/or identity before fulfilling your request. We will comply with such requests to the extent required by applicable law or the US-Swiss Privacy Shield and US-EU Privacy Shield.


What happens if I want to stop using Nufisys Apps?

If you stop using the Nufisys service at any time, the content you shared will remain available to other users.

There is no way you may delete content you already shared on Nufisys services. Therefore, unless it was unpublished by Nufisys, it will continue to be accessible to you and others who may access the Service.


What happens if Nufisys closes my account?

If Nufisys deactivates your account due to a TOS violation, then you may contact us to request deletion of your account data, and we will evaluate such requests on a case by case basis, pursuant to our legal obligations.


Where do Nufisys Apps store my information?

When you use Nufisys Software on your computing device, such as by using one of our downloadable applications, some of your data will be stored locally on that device.

When you sync your computing device with the Service, that data will be replicated on servers maintained in Europe. This means that if you store information in or submit data to the Nufisys website or Nufisys Software and sync such Nufisys Software with the Nufisys service, you acknowledge your personal information will be transmitted to, hosted, and accessed in Europe.

Data privacy laws or regulations in your home country may differ from those in Europe. We will collect, store, and use your personal information in accordance with this Privacy Policy and applicable laws, wherever it is processed.

How do Nufisys Apps comply with data transfer rules?

If you are a resident of the European Economic Area (“EEA”) or Switzerland, please note that we use standard contractual clauses approved by the European Commission to transfer your personal Information from the EEA or Switzerland to the United States and other countries.
