1. What is our Zero-Knowledge Policy?

We employ a Zero-Knowledge architecture, which ensures that we do not have access to your encryption keys, or the content of your communications. This means we can’t read your messages or access your files. Only you and those you choose to share with can access them.

 

When you use our services, the personal information you provide (such as your mobile number or email address) is encoded at the source on your device using a one-way hash algorithm. This algorithm converts the data into a unique unbreakable code that even we cannot read. There is no point in time when your data is visible to the servers or service administrators.

 

We make your content readable to you alone. Most encryption systems only encrypt your data during transmission. This means that anyone with physical access to the servers on which your data is stored (such as the company’s staff) could have access to it.

The one-way encoding process we use is comprehensive – even with physical access to the servers, third-parties and even Suraxa cannot read your data. All they can see are sequentially numbered rows of encoded undecipherable data.

 

Your message content and data for your third-party service providers (such as Gmail, Outlook, or Google Drive) are never sent to the Suraxa servers. If you choose to have a Suraxa IM account or Suraxa Cloud account, your content and data will follow the same comprehensive encryption process and will be stored on the Suraxa server. In both cases, your device will encrypt the message content and send it to the server.  Your third-party service provider and even Suraxa will not be able to decrypt and read your content. Only you have the ability to decrypt and read your data. The encryption key required to decrypt the data you share with a contact is sent via a separate channel using a separate Suraxa server. This encryption key is also encrypted by your device and only you will be able to decrypt it, even Suraxa will not be able to access this data.

 

All data passing through the client is encrypted by default and plain data (in a readable format) never leaves your device unless you specifically select it. Your private encryption key used to encrypt the data is never shared with anyone, even Suraxa does not have it.

You can also sync your contacts with the Suraxa servers so that you can connect with your contacts. This contact data also follows our strict Zero Knowledge policy, which means that it is encoded at the source using a one-way hash algorithm. This algorithm converts the data into a unique unbreakable code that even we cannot read. There is no point in time when your contact data is visible to the servers or service administrators.

 

At registration, you have the option to enter an email address so that we can send you marketing and promotional updates. This information will be encrypted but it will not be converted using a one-way hash algorithm into a unique unbreakable code because we may need to read the data so that we can send you marketing and promotional updates and for password recovery purposes.

 

Some of the data you provide may need to be decrypted for lawful purposes and for compliance with our legal obligations.

 

Moreover, our decentralised design means that data isn’t stored in a single location, which reduces the risk of data breaches and enhances your privacy.

 

2. Information We Do Not Collect:

We prioritise your privacy and have intentionally designed our services to minimise the amount of personal data we collect and store. We follow the principle of data minimisation, collecting only what is necessary for providing and improving our services.

Zero-Knowledge Architecture: Critical to our privacy approach is our Zero-Knowledge architecture. This design ensures that we do not have access to certain types of sensitive data, maintaining a boundary between us and your personal content.

Encryption Keys: Your encryption keys are generated and stored on your device. These keys are never transmitted to us or any third parties, and they remain entirely within your control.

Content of Communications: We do not have access to the content of your communications, including messages, emails, files, or shared content. This data is encrypted and can only be decrypted with your unique encryption keys. Only you and the people you choose to share with can access this content.

Passwords: Your passwords are stored using advanced hash functions. This means we don't know and can't access your password.

Our Zero-Knowledge policy reinforces our commitment to privacy by ensuring that your most sensitive data remains under your control at all times. This design means that even in the unlikely event of a data breach, your sensitive data remains secure and inaccessible.

 

3. What Information We Collect:

The data we collect depends on how you interact with Suraxa, the choices you make, including your privacy settings, and the products and features you use. We categorise this information based on when and why it is collected as follows:

  • Information Required for Purchase: To purchase our services, we may need to collect certain personal identification information from you. This information allows us to process your order and provide you with the services you've purchased. It can include:
    • Payment information
    • Billing address
    • Email address
    • Name
  • Information Required for Using the Services: To create an account and use our services, we may need to collect certain personal identification information and sensitive user information from you. This information enables us to set up your account, enable secure login, and personalise your experience. This can include:
    • Username
    • Encrypted password
    • Phone number
    • Contacts
  • Information Collected During Use Of Services: While using our services, we may collect certain non-identifying and sensitive information. This information helps us understand how our services are being used, track and improve performance, secure our services, and personalise your experience. It can include:
    • IP address
    • Device ID and Hardware Information
    • Browser Type and version
    • Operating system Information
    • Network information
    • Account activity (e.g. Features used, settings changed)
       
  • Personal and Sensitive User Information: While our Zero-Knowledge architecture prevents us from accessing certain sensitive information, such as your encryption keys and the content of your communications, we may still collect other sensitive information as necessary to provide our services. For example: Account credentials: We collect and store your account credentials, such as your username and password, to enable you to log in and use our services. Your password is stored using advanced hash functions so we can't access it.
  • Your Contacts And Others. Phonebook, and Contacts Information that you permit are collected by us in order to allow you to communicate with other users. Users with whom you communicate can store or reshare your information (including your phone number or messages) with others on and off our Services.
  • Sensitive Information from Google OAuth Services – GMail and Google Drive: In order for our users to use Suraxa Cloud efficiently, users have the option to connect their Cloud accounts, which are hosted on Google with Suraxa. At the time of connecting these accounts, we will require users to undertake a Google OAuth consent. During this stage, users will be required to authorise Suraxa to access certain pieces of information. The information that we collect from our users are:
      • Google Contacts API: Suraxa uses the “./auth/contacts.readonly” api as it is essential for the application to function effectively. This permission enables the application to access contact information, specifically email addresses, which is crucial for its encryption functionality. The Suraxa application utilises the provided scope to retrieve contact email addresses from the user's account. This information is used to locate the corresponding public keys associated with each contact. These public keys play a pivotal role in the encryption process.
        When a user composes and sends an email through the application to one of their contacts, the application employs a dual-key encryption mechanism. The data within the email is encrypted using a data key. This data key is then further encrypted using the recipient contact's public key and the sender's private key.
         
      • GMail API: Suraxa uses the "https://mail.google.com/" permission as the application functions as an email client, enabling users to connect various email hosting accounts. Suraxa allows users to manage their emails, including reading, organising folders, composing, and sending secure emails. For secure emails received, the application decrypts and displays content.
         
      • Google Drive API for productivity and Drive Syncing at client level: Suraxa uses the "/auth/drive" allows the Suraxa app to securely sync encrypted files on user's Google Drive. Consent is obtained to access Drive for uploading new files, downloading, editing, and re-uploading existing files. This sync functionality ensures auto-updates across user's multiple devices using Suraxa application.
         
  • Information Collected From Third Parties:  We may receive information about you from other sources to help us correct or supplement our records, improve the quality or personalisation of our services, and prevent or detect fraud. We may also collect information from third parties if you choose to use third-party integrations or connect your Suraxa account with a third-party service.

 

4. How We Collect Information

We collect information from you in various ways when you use our services. Here is a breakdown of how we gather your data:
 

Information Provided by the User:

Most of the personal information we collect is provided directly by you. For instance, you give us your name, email, and billing address when you purchase our services; your username and encrypted password when you create an account; and your communications preferences when you update your settings or preferences.

 

Information Collected Automatically

Some information is collected automatically when you use our services. This includes non-identifying information and certain sensitive information related to your use of the services. Examples of automatically collected data include your IP address, device ID, browser type, and account activity. We may use technologies like cookies, log files, or analytic tools to help us collect this data.

 

Information Collected Through Audit Trails

In some cases, and particularly when any of our user subscribe to our audit trail feature, we collect data on user activity for auditing purposes for any content owned by that user. These audit trails log the actions that any user, whether it be the content owner or any user with whom this content has been shared and they have been given access to, perform, such as but not limited to viewing, modifying, or sharing. This allows the owner of the content to track and monitor how their content is being used.

 

It's important to note that even when a user who has accessed another user's content deletes their account with Suraxa, the audit logs pertaining to their activity remain intact for the content owner's audit purposes. The Audit log for any content includes but is not limited to, time, user id, device related information, IP data

 

Information Collected from Third-Party Sources

We may also receive information about you from third parties. This can happen if you choose to use third-party integrations, connect your Suraxa account with a third-party service, or when we contract with third parties to improve the quality or personalisation of our services, or to prevent or detect fraud.

 

Decentralised Data Collection

Owing to the decentralised nature of Suraxa, some of the information we collect is gathered locally on your device rather than centrally. This ensures that you maintain full control over your data. For example, your encryption keys are generated and stored on your device and never transmitted to us or any third parties. This local data collection contributes to your privacy and security.

 

 

5. Why We Collect Information

We collect your information for various purposes. The data we gather helps us to provide and improve our services, to personalise your experience, and to communicate with you effectively. Here's a more detailed look at why we collect your data:

  • To Provide and Maintain Our Services: We need certain information to deliver our services to you and ensure they function as intended. For instance, we require your account credentials to create your account and enable you to log in, and we use your billing information to process your purchases. Some of our unique features, like "Lock Content to Device" or "Watermarking," require specific data (like your device ID) to function correctly.

 

  • To Improve User Experience: We use data about how you use our services to understand and analyse the usage trends and preferences of our users, to improve our services, and to develop new products, services, features, and functionalities. For example, knowing your device type and operating system helps us identify platform-specific limitations and communicate these to you to enhance your experience.
     
  • To Ensure Privacy and Security: We collect certain data to safeguard your privacy and ensure the security of our services.

  • Our Commitment to Zero-Knowledge: Our Zero-Knowledge architecture means that we limit our access to your personal data to what's strictly necessary to provide the service. We don’t use your personal data for anything beyond this, as we can't access the content of your communications or your encryption keys. This commitment ensures that your privacy is respected and protected at all times.

 

7. Legal Grounds for Processing Your Information

We process your personal data based on certain legal grounds, depending on the nature of the data and the specific context in which we collect it. The legal bases for our processing of your personal data typically fall into one of the following categories:

  • Consent: We may process your data if you have given us explicit consent to use your personal information for a specific purpose. For example, we require your consent to use your data to provide you with promotional communications.
  • Performance of a Contract: We may process your data when it's necessary for the performance of a contract to which you are a party, or in order to take steps prior to entering into a contract. For instance, we need to process your payment information to fulfill our contract and provide you with the services you purchase.
  • Legal Obligations: We may process your data when we're required to by law. For instance, we may need to collect and store your data to comply with legal obligations relating to tax, to respond to legal requests, or prevent fraudulent activities.
  • Legitimate Interests: We may process your data when it's necessary for the purposes of the legitimate interests pursued by us or by a third party, provided those interests are not overridden by your interests or fundamental rights and freedom. For example, we may process your data to protect you, us, or others from threats (such as security threats or fraud), comply with laws, enable or administer our business, manage corporate transactions, or understand and improve our relationships with customers.

 

 

 

8. Information Sharing and Disclosure:

 At Siccura Ltd, we uphold stringent measures to maintain your privacy. We only share your personal data under limited circumstances, as outlined below:

  • When and Why We Share Information: The scenarios in which we might share your information include providing our services, complying with legal obligations, protecting the rights and safety of our users and third parties, and in connection with corporate transactions (like a merger or acquisition).
     
  • Third Parties with Whom Information May Be Shared: We may share your data with certain third parties in alignment with our services and operational requirements. These third parties could include service providers and advisors, law enforcement, and potential business partners.
     
  • Access to Your Information: As per our commitment to a Zero-Knowledge policy and our decentralised architecture, the content of your communications and your encryption keys are accessible only to you. However, certain data, such as your contact information and billing details, may be accessed by our team when necessary to provide our services or support. Any request for access to your data is handled strictly, with a strong emphasis on preserving your privacy and maintaining our services' security.
     
  • Audit Trail Information: For users who subscribe to our audit trail feature, the audit logs generated by accessing and manipulating data may be shared with the data owner. This process is conducted in a manner that respects all users' privacy and is compliant with our privacy policy.
     
  • Data for “Data Privacy and Security”: Certain information, such as your device ID, is used to execute functions for data privacy and security. This information is essential for our services' operation but is not visible or accessible to any third party, nor to Suraxa.

9. Data Security:

At Siccura Ltd, we prioritise your data security and take extensive measures to protect your information against unauthorised access, alteration, disclosure, or destruction. We are dedicated to providing a safe and secure environment for our users.

  • Security Measures: We employ a range of security measures including the use of secure networks, encryption, and anonymisation techniques such as data hashing. Our servers and computer environments are safeguarded by robust physical and electronic security measures. Access to your personal data by our team is strictly controlled and limited only to those who require it to perform their job functions.
  • Zero-Knowledge and Decentralisation: A core aspect of our commitment to data security is our Zero-Knowledge architecture. This means that the content of your communications and your encryption keys are never visible to us. Only you have access to this sensitive information, which ensures that we can’t use your personal data beyond what is necessary to provide the service.
     

Furthermore, our services employ a decentralised architecture. This means that some data is stored locally on your device rather than on central servers. This design further minimises the risk of your data being compromised.

  • Data Hashing: We use data hashing techniques to ensure the confidentiality of your sensitive information. Hashing is a form of cryptography that transforms data into a unique, fixed length string of text, which is virtually impossible to reverse-engineer. This ensures that even if your data were intercepted in some manner, it would remain unintelligible without the correct hash key.
  • Data Breach Notification: Despite our stringent security measures, no method of transmission over the internet or electronic storage is 100% secure. In the unfortunate event of a data breach, we commit to notify you and the relevant authorities, as required by law, promptly. We will also take all reasonable steps to mitigate the effects and to prevent any further data breaches.

  • Deleting your account will result in the loss of all data and content associated with your account. Be aware that this includes the decryption keys for your secured data, rendering all such data irretrievable. Please also note that data shared with other users will remain accessible to them, as they have already been granted the decryption key and access rights, even after you delete your account. We plan to develop functionality in the future to render all shared data useless in such scenarios, should that be required.
     
  • Decentralised Data RetentionDue to our decentralised architecture, some of the data is stored locally on your device. When you delete your data or account, it removes the information from your device. However, any shared data, or data stored on the devices of other users due to our decentralised nature, may remain accessible to those users or on those devices, unless they also delete it.
     
  • Audit Trail: Please note that, if you have subscribed to our Audit Trail feature, the audit log data associated with other users’ actions on your shared data will be retained, even if those users delete their accounts. This allows us to preserve the integrity of the audit trail for you.
