Information Collected and Received


When You install the NumberBook Social App, NumberBook Social will collect some technical information from Your device in order to be able to provide You with the Services, namely Your IP address, the unique device ID number and what operating system, operator, screen resolution and version of the NumberBook Social App You use. This information is used to verify that the User device is properly registered and will not be used to identify You personally or be transferred to third parties. We will, however, use this data for statistics and user support as long as You use the Services.

For details regarding permission usage in connection with installation on the Android platform, please see the NumberBook Social FAQ at ( http address)

User Profile

Where the User registers a user profile in the NumberBook Social App and confirms being the holder of a certain number via an sms, the information up-loaded to the profile section of the NumberBook Social App will be received and stored by NumberBook Social 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 including, 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.

Please note that the User personally is responsible for any Content up-loaded to and displayed in the user profile.



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 NumberBook Social 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

If You decide to share your Contact Information with NumberBook Social, we will only use Contact Information for the sole purpose of recognizing and recommending You to people You may know within the NumberBook Social community. Sharing your Contact Information with NumberBook Social is necessary if You wish to use the NumberBook Social Chat service. If You decide not to share your Contact Information with NumberBook Social, you will not be able to access and use NumberBook Social Chat. You will only be able to benefit from a limited access to and use of the Service.

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 NumberBook Social App, NumberBook Social 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 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 NumberBook Social. Addresses, passwords and credit card numbers and any other similar information will automatically be prevented from being entered into the NumberBook Social 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 NumberBook Social 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. However if you choose not to share your Contact Information with NumberBook Social, you will not be able to use the NumberBook Social Chat and you will have a very limited access to the Service.

Call Block

Where a User within the Services reports a phone number as spam, NumberBook Social 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.

Information not collected

NumberBook Social does not collect emails, addresses or other contact information from its users’ mobile address book or contact lists other than names and mobile phone numbers. We do not collect location data, but users may voluntarily share their location with other users via the Service. However, for iPhone and Windows phone Users, their location should be accessible in order to be able to access and use the Caller ID service.

In NumberBook Social Chat service, the contents of messages that have been delivered by the Service are not copied, kept or archived by NumberBook Social in the normal course of business. The Service is meant to be an SMS replacement, using data service through a User’s phone (either via cell network or Wi-Fi). Users type their messages, which are sent via data service to our servers, and routed to the intended recipient (who must also be a NumberBook Social User), if that recipient is online. If the recipient is not online, the undelivered message is held in NumberBook Social’s server until it can be delivered. If the message is undelivered for thirty (30) days, the undelivered message is deleted from our servers. Once a message has been delivered, it no longer resides on our servers. The contents of any delivered messages are not kept or retained by NumberBook Social— the only records of the content of any delivered messages reside directly on the sender’s and recipient’s mobile devices (and which may be deleted at the user’s option). Notwithstanding the above, NumberBook Social may retain date and time stamp information associated with successfully delivered messages and the mobile phone numbers involved in the messages, as well as any other information which NumberBook Social is legally compelled to collect. Files that are sent through the Service will reside on our servers after delivery for a short period of time, but are deleted and stripped of any identifiable information within a short period of time in accordance with our general retention policies.
