REM, WalletOn and all WDI Applications
Privacy Policy

World Data (WDI) beliefs in giving users absolute control over their private data, enabling them to be SELF-SOVEREIGN.

Collection and Use of Non-Personal Information

We collect data in a form that does not, on its own, permit direct association with any specific individual. We may collect, use, transfer, and disclose non-personal information for any purpose. The following are some examples of non-personal information that we collect and how we may use it:

  • We may collect information such as occupation, language, zip code, area code, unique device identifier, referrer URL, location, and the time zone where a World Data product is used so that we can better understand customer behavior and improve our products, services, and advertising.
  • We may collect information regarding customer activities on our World Data Cloud & App services.
  • This information is aggregated and used to help us provide more useful information to our customers and to understand which parts of our World Data & App services are of most interest. Aggregated data is considered non‑personal information for the purposes of this Privacy Policy.
  • We may collect and store details of how you use our services, including search queries. This information may be used to improve the relevancy of results provided by our services. Except in limited instances to ensure quality of our services over the Internet, such information will not be associated with your IP address.

With your explicit consent, we may collect data about how you use your device(s) and applications in order to help app developers improve their apps.

Disclosure for collecting data related to contact lists and images.


The REM ID and WDI REM Play are Sovereign apps that protect users’ data privacy and security. They do this by storing data locally on the user’s device rather than in the cloud, which means the data is inaccessible to third parties, including the app developer.

When it comes to contact lists and images, both sovereign apps use the following principles to collect and use data:

  • **Data minimization: Only the necessary data for the app to function is collected.
  • **Consent: Users must explicitly consent to collecting their data.
  • **Transparency: Users are given clear information about how their data is collected and used.
  • **Data security: The data is stored securely and protected from unauthorized access.

For example, both apps referred to above are sovereign apps that allow users to send messages to each other. The app would only collect the contact information of the users using it. This information would create a contact list, permitting users to find each other easily. The app would also collect the images that users send to each other. These images would be stored locally on the user’s device and not shared with third parties.

By following these principles, both sovereign apps can help protect users’ data’s privacy and security.

Taking Control of Your Data

At REM ID or WDI REM Play, we respect your right to control your personal information. That’s why we built your data as yours, residing solely on your device and never shared with us or any third party. When you’re ready to move on, you have the ultimate power: uninstall the app from your phone. This instantly and permanently deletes all your data, including any personal information you entered or generated within the app. We don’t retain backups or copies, so what you remove is truly gone. Remember, once uninstalled, we cannot recover your data or information, so ensure you’ve saved anything essential before letting go.

Protection of Personal Information

World Data uses the W3C standards and principles to implement self-sovereign identity for its REM ID app.  Please note that standards have not being completed so World Data may use proprietary algorithms to ensure end user control of his/her private data.

Location-Based Services

To provide location-based services on World Data products, World Data and our partners and licensees, such as maps data providers, may collect, use, and share precise location data, including the real-time geographic location of your World Data computer or device. Where available, location-based services may use GPS, Bluetooth, and your IP Address, along with crowd-sourced Wi-Fi hotspot and cell tower locations, and other technologies to determine your devices’ approximate location. Unless you provide consent, this location data is collected anonymously in a form that does not personally identify you and is used by World Data and our partners and licensees to provide and improve location-based products and services. For example, your device may share its geographic location with application providers when you opt-in to their location services.


Customer mobile numbers will not be shared or sold to third parties.

As part of our commitment to protecting end user privacy, we want to assure you that we will not share or sell your mobile number to any third parties. This means that your mobile number will be kept strictly confidential and used only for purposes related to providing you with our products and services.

By keeping your mobile number private, we aim to provide you with peace of mind and ensure that your personal information is kept secure. We use industry-standard security measures to safeguard your data and have strict policies and procedures in place to ensure that your information is handled with the utmost care.
