Privacy Policy

Privacy Policy

The DU Caller software ("DU Caller", "we", "us", or "our") values your privacy. In this Privacy Policy ("Policy"), we describe how we collect, use, and disclose information that we obtain about visitors to our website, users of our mobile application DU Caller (the "App"), and the services available through our Site and our App (collectively, the "services").

By using our App or any of our services, you agree that your personal information will be handled as described in this Policy. Your use of our App or Services, and any dispute over privacy, is subject to this Policy.

Being a collaborative community the top-priority of DU Caller will always be the relationship with its community. We are therefore firmly committed to the security and protection of the personal integrity of our Users of the Services and their contacts.

This Privacy Policy describes what personal information You may share with DU Caller, as data controller, and other Users when activating and using the DU Caller Services, how DU Caller receives, collects and uses this data and how You may opt-out at any time, altogether preventing use of the data shared via the Services.

1. Information Collected and Received

Installation and Use

When you install and use the DU Caller Apps, DU Caller will collect, process and retain personal information from You and any devices You may use in Your interaction with our Services. This information may include the following: geo-location, Your IP address, device ID or unique identifier, device manufacturer and type, device and hardware settings, ID for advertising, ad data, operating system, operator, IMSI, connection information, screen resolution, usage statistics, device log and event information, incoming and outgoing calls and messages, times and date of calls, duration of calls, version of the DU Caller Apps You use and other information based on Your interaction with our Services. DU Caller may use the information collected from, and in connection with, all of our services to provide, maintain, and improve them, to develop new ones, and to protect DU Caller and its users. DU Caller also uses this information to provide you with tailored content, such as search results and advertisements more relevant to You.

User Profile

Where the User registers a user profile in the DU Caller Apps and via SMS or inbound call verification confirms being the holder of a certain number, the information up-loaded to the profile section of the DU Caller Apps will be received and stored by DU Caller until the User changes or deletes such data or terminates the Services. Compulsory information when creating a profile page is the User's first name, last name and phone number and additional information that may be provided at the User's option include, but is not limited to, photo, gender, street address and zip code, country of residence, email address, professional website, Facebook page, Twitter address and a short status message. DU Caller may supplement the information provided or collected with information from third parties and add it to information provided by You. For example, collection and use of demographic information that is publicly available and additional contact information as allowed by applicable national laws.

Please note that any content uploaded to and displayed in the user profile by the User is not moderated by DU Caller. The User is solely liable for the publication of such content.


In addition, You may provide us with Your user identifier information regarding certain third party services, i.e. Facebook, Google+, LinkedIn and Twitter, necessary for the application to interoperate with such third party services. In that case DU Caller will store and process also that information (and also a mapped photo where applicable), for as long as You use the Services and will not use this information for any other purpose than required in order to obtain interoperability and functionality in relation to such third party services. Please note that we never store any passwords to the mentioned third party services.

Contact Information

Where the DU Caller Apps are obtained from other sources than Apple App Store or Google Play, You may share the names, numbers and email addresses contained in Your device's address book ("Contact Information") with DU Caller for the purpose described below under Enhanced Search. If you provide us with personal information about someone else, you confirm that they are aware that You have provided their data and that they consent to our processing of their data according to our Privacy Policy.

Where the DU Caller Apps are obtained from Google Play, we will only use permitted Contact Information to make our Services more relevant to You and Your engagement with the DU Caller community.

In addition to Contact Information, if You choose to activate use of a third party social network service, such as Facebook, Google+, LinkedIn or Twitter, within the DU Caller Apps, DU Caller may up-load, store and use the list of identifiers associated with said services linked to the Contact Information in order to enhance the results shared with other Users.

Please note that no other Contact Information than the phone numbers and thereto attached names and email addresses will be received, stored and used from the User's address book. Other numbers or information that may be contained in your device's phone book will be filtered away and will therefore not be stored or used by DU Caller. Addresses, passwords and credit card numbers and any other similar information will automatically be prevented from being entered into the DU Caller database by our safety algorithms, that filters any numbers and other information stored in the phone book in a number sequence not compatible with that used for telephone numbers. Please also note that You can always choose not to share Contact Information with DU Caller and if You have shared information and changed Your mind, You can easily delist Your number or opt-out to render your entire Contact Information unavailable for search in the database for Enhanced Search.

The app accesses the contacts on the phone in order to display the contacts that were recorded and so the app can record or ignore calls from specific contacts. The contacts information is NOT transmitted nor stored on any server.

Name tagging

We may also associate a name with a phone number through the name tagging functionality, which allows a User who receives a call from a phone number which is not associated with a name in the DU Caller database to indicate a name to be associated with that number. A name will only be associated with a number through this functionality if a sufficient number of independent Users, based on our algorithm, have indicated the same name for the relevant number.

Call Block

Where a User within the Services reports a phone number as spam, DU Caller stores that phone number in combination with the User's RegisterID in order to maintain the User's spam list online but also for the purpose of building a community based spam blocking directory. On the Android platform, the User can also add a name to the phone number in question that will only be visible to that User.


With the DU Caller app You are provided with an SMS and MMS messaging service. In order to facilitate the delivery of your messages through the app, DU Caller may store your messages in encrypted form for a limited period of time. However, DU Caller does not monitor the content of such messages.

Recording Call - Microphone access

We do not hold any recordings or user information on our own servers. DU Caller records phone calls. All recorded calls are recorded on the phone using the microphone on the device. The recorded files and related notes are stored on the phone's storage and NO server is involved with recording phone calls. The recorded calls are not stored on our own server and can only be stored locally or on a third party cloud storage service such as Google Drive or Dropbox.


The app requests permission to access the phone's storage only in order to store the recorded calls and play the recorded files afterwards. The app does not access any other files nor excess user's photos.

2. Use, Sharing and Disclosure of User and Contact Information

Information related to the User or Contact Information will be used to:

i. Display the name associated with a certain number at a manual number search against the DU Caller database.

ii. Automatically display the caller's name when a call is received, as enabled by the Enhanced Search functionality, as described below, to Users who have activated that functionality, and indicate possible common connections with the caller or when an incoming call may be spam.

iii. Display the "who viewed my profile" and "availability" functionalities of the Services.

iv. Provide selected DU Caller partners with limited information in order to enhance user experience, service functionality and data accuracy, provided that these partners adhere to strict confidentiality provisions no less protective of your rights than this Privacy Policy.

v. Enable the DU Caller Name Search, as described below, to Users who have activated that functionality.

vi. Contact You from DU Caller for verification purposes or with information pertaining to the Services, e.g. newsletter e-mails and similar notifications, and verify provided User Profile information with third party providers.

vii. Deliver messages through the DU Caller app.

viii. Enable You to use and share Your user information in connection with Your use of third party services.

(i) Customize, maintain, measuree, improve our Services and develop new ones.

(j) Personalize, measure and improve our advertising and use geo-location information to provide You with location based information and services (such as more relevant advertising, search results and other personalized content).

Enhanced Search functionality and database

To improve the Services, DU Caller has created a searchable database where the Users generate the content and via the Enhanced Search functionality are offered access to this database, containing Contact Information from those Users who permit such aggregation. In return these Users are allowed to access to the database by querying it. Queries against the database are only allowed through the DU Caller Services by Users who have explicitly approved of the Service's functionality and integrity restrictions as contained in the DU Caller Privacy Policy.

The queries against the DU Caller Enhanced Search database are processed only if a numeric phone number is attributed to the query and only if no results are published by an associated or partnering database of DU Caller. The response given to the queried number will be the associated name to that number, if any name is available.

It is important to notice the following distinctions. As an integrity and security measure, only numeric queries are allowed against the DU Caller database for Enhanced Search, i.e. there will be no result to a name query. Name searches may, however, give result via the Services if a partnering or associated database to DU Caller has numbers available to the name queries. The Users contributing to Enhanced Search can therefore rely on that the Contact Information provided, as a personal integrity precaution, will not enable anyone searching for the number to a certain person direct access to that number. In some cases, Users may, however, use the Services to forward a request to a named person in order to get in touch, please see below about the DU Caller Name Search service.

The database may also - via a "social graph" algorithm - be used to show the User what other Users he or she, directly or indirectly, has in common with another User and to suggest other contacts they may have in common. Please note that, if You are presented as a person that the User who made the query may know or as a "similar" person, some of Your profile information entered by you, excluding phone number, will be disclosed to such User.

Name Search

Your name and telephone number and any other information You choose to submit on Your User Profile will be visible to the person You reach out to when requesting a contact via the DU Caller Name Search service. Your request will be forwarded to that person via an SMS and he or she may choose to share the phone number with You (of which You in such case will be informed of via a push notification), or not, at his or her own discretion, but may also block further request from You or to opt-out of the service altogether at any time. Nobody will under any circumstances receive more than three contact requests via the DU Caller Name Search service during any 24 hours and has anybody received nine requests during the last 72 hours, that person will not receive additional requests for the next 72 hours. Excessive requests not delivered will be put on hold in chronological order, unless the recipient actively allows further requests to be forwarded.

Via the DU Caller Name Search service You may be recommended, via a push notification, when there are new contacts that you may know and be interested in getting in touch with.

Opt-Out and Delist Numbers

If a User chooses to disable the Enhanced Search functionality, the Contact Information made available by that User is disabled and will thereafter not be accessible for queries. If any persons do not wish to have their names and phone numbers made available through the Enhanced Search or Name Search functionalities, they can exclude themselves from further queries by notifying DU Caller via


In addition to the above DU Caller may disclose information related to the Users and Contact Information if we believe such action is necessary to:

(i) Comply with the law, or legal process served on us

(ii) Protect and defend our rights or property (including the enforcement of our agreements);

(iii) Act in urgent circumstances to protect the personal safety of Users or members of the public.

DU Caller may share Your personal data with trusted third party service providers and partners. DU Caller will always require these third parties to take appropriate organizational and technical measures to protect your personal data and traffic data and to observe the relevant legislation.

The following is a description of how DU Caller may share information about You with trusted third party partners:

(i) DU Caller uses a third party partner company in order to send You or a third party you wish to contact SMS when you use the Services. In order to send you the SMS, we send the third party company Your and the relevant third party's phone numbers. This third party SMS partner is contractually obligated only to use these phone numbers for the transmission of requested SMS.

(ii) DU Caller may use Push Notification Services to notify you about up-dates and important information. In such cases, Your phone number may be part of the notification. This message is sent to the push notification service provider, for delivery to Your device. You may, however, at any time-opt out or disable push notifications in the DU Caller Apps.

(iii) DU Caller may allow you to use third party services to create your user profile or log in to use our Services, share information with such third parties, or to connect your user profile with the respective third parties. Those third parties may automatically provide us with access to certain personal information retained by them about You (e.g., content viewed by you, content liked by You and information about the advertisements you have been shown or may have clicked on). You control the personal information You allow us to have access to through the privacy settings on the respective third party service and the permissions You give us when You grant us access to the personal information about You retained by the respective third party service. By associating an account managed by a third party with Your DU Caller user profile and authorizing us to have access to this information, You agree that we may collect, use and retain the information provided by these third party services in accordance with this Privacy Policy.

(iv) For the provision of free versions of the Services, DU Caller may also collaborate with a few selected third party advertising networks, which in such case may be provided limited information related to the freemium User's device (but no other User or Contact Information).

(v) DU Caller, or a third party on its behalf, may collect and use your email address, telephone number and ID for advertising (including, but not limited to, content viewed by you, content you have commented on and information about the advertisements you have been shown or may have clicked on) through the DU Caller Apps and share this information with third party advertisers and networks. Such third parties may use this information and information collected from other sources in order to provide measurement services and targeted ads. You can limit or opt-out of the collection and use of Your information for ad targeting by third parties via Your device settings.

You are at no time under any obligation to provide any of such data. Any and all information which is voluntarily submitted in feedback forms or any surveys that You accept to take part in is used for the purposes of reviewing this feedback and improving the DU Caller software, products and websites.
