Privacy Policy

FileString exists to keep your files as private as you want them. We take your privacy just as seriously.

Last modified: March 15, 2018

The FileString Service is designed to enable users to share their files with control such that users are able to protect, track, push updates and revoke access to those shared files by recipients. In order to enable sharing, tracking and analytics, each user must have a service identity. To create your service identity, we must collect basic information from you. As you use our service, we want you to be clear how we’re using information and the ways in which you can protect your privacy.

Our Privacy Policy explains:

  • What information we collect.
  • Why we collect it.
  • How we use it.

We’ve tried to keep this as simple as possible, but if you’re not familiar with terms such as “personal information”, “IP addresses”, and “cookies”, you can read about these terms at the bottom of this page. Your privacy matters to FileString so whether you are new to FileString or a long-time user, please do take the time to get to know our practices – and if you have any questions contact us through our website contact form.

Information we collect

We collect information to provide services to all of our users – from figuring out basic stuff like which language you speak, to more complex things like enabling you to share and protect your files and analyze and track how other people are using them.

We collect information in two ways:

  • Information you give us. For example, the FileString service requires you to sign up for an account. When you do, we’ll ask for personal information including your name, email address, telephone number or billing information. We also gather information from you when you have problems using the service or have suggestions about how to improve the service.
  • Information we get from your use of our service. We may collect information about the service that you use and how you use them, such as how you use features of our software or who and how you share files with other people. We may collect this information while you are using our website, desktop software or mobile device software. This information includes:
    • Device information
      We may collect device-specific information (such as your hardware model, operating system version, unique device identifiers, and mobile network information). FileString may associate your device identifiers with your FileString Account.
    • Activity Information
      When you use our website or software, we may automatically collect and store certain information in our secure database. This may include:

      • Details of how you used our service, such as features you used and other users with whom you share files.
      • Your MAC address, Device ID or IP address.
      • Device event information such as crashes, system activity, hardware settings, browser type, browser language, and the date and time of your request.
      • Cookies that may uniquely identify your browser or your FileString Account.
      • Aggregate data about your service usage including the volume of files you share and how often you manage those files.
    • Unique application numbers
      Each FileString software client application includes a unique version number. This number and information about your installation (for example, the operating system type) may be sent to FileString when you install or uninstall the application or when that service periodically contacts our servers, such as for automatic updates.
    • Local storage
      We may collect and store information (including personal information) locally on your device using mechanisms such as browser web storage (including HTML 5) and application data caches.
    • Cookies and anonymous identifiers
      We use various technologies to collect and store information when you visit a FileString service, and this may include sending one or more cookies or anonymous identifiers to your device. We also use cookies and anonymous identifiers when you interact with services we offer to our partners, such as content services or FileString features that may appear on other sites.

How we use information we collect

We use the information we collect from our service to provide, maintain, protect and improve the service and to protect FileString and our users. We may also use this information to offer you tailored services.

When you contact FileString, we may keep a record of your communication to help solve any issues you might be facing. We may use your email address to inform you about our service, such as letting you know about upcoming changes or improvements.

We use information collected from cookies and other technologies to improve your user experience and the overall quality of our services.

We will ask for your consent before using information for a purpose other than those that are set out in this Privacy Policy.

FileString may process personal information on our servers in many countries around the world. We may process your personal information on a server located outside the country where you live.

Information we share

We do not share personal information with companies, organizations and individuals outside of FileString unless one of the following circumstances apply:

  • With your consent. We will share personal information with companies, organizations or individuals outside of FileString when we have your consent to do so. We require opt-in consent for the sharing of any personal information.
  • With company or domain administrators or people you designate as co-owners or re-sharers of your files. If your FileString Account is managed for you by a domain or company administrator, then your domain administrator who provides user support to your organization will have access to your FileString Account information (including your email and other data). Your domain administrator may be able to: View statistics regarding your account, such as statistics regarding your usage of our service and software; change your account password; suspend or terminate your account access; access or retain information stored as part of your account; receive your account information in order to satisfy applicable law, regulation, legal process or enforceable governmental request; restrict your ability to change certain account settings.
  • For external processing
    We provide personal information to our affiliates or other trusted businesses or persons to process it for us, based on our instructions and in compliance with our Privacy Policy and any other appropriate confidentiality and security measures.
  • For legal reasons
    We will share personal information with companies, organizations or individuals outside of FileString if we have a good-faith belief that access, use, preservation or disclosure of the information is reasonably necessary to: Meet any applicable law, regulation, legal process or enforceable governmental request; enforce applicable Terms of Service, including investigation of potential violations; detect, prevent, or otherwise address fraud, security or technical issues; protect against harm to the rights, property or safety of FileString, our users or the public as required or permitted by law.

We may share aggregated, non-personally identifiable information publicly and with our partners. For example, we may share information publicly to show trends about the general use of our services.

If FileString is involved in a merger, acquisition or asset sale, we will continue to ensure the confidentiality of any personal information and give affected users notice before personal information is transferred or becomes subject to a different privacy policy.

Information security

We work hard to protect FileString and our users from unauthorized access to or unauthorized alteration, disclosure or destruction of information we hold. In particular:

  • We encrypt your personal information and your files within our service and software.
  • We require user authentication to access your FileString account and FileString services.
  • We periodically review our information collection, storage and processing practices, including physical security measures, to guard against unauthorized access to systems.
  • We restrict access to personal information to FileString employees, contractors and agents who need to know that information in order to process it for us, and who are subject to strict contractual confidentiality obligations and may be disciplined or terminated if they fail to meet these obligations.


Our Privacy Policy applies to the FileString service and software and any services provided to and you and through FileString by our partners or affiliates but excludes services that have separate privacy policies that do not incorporate this Privacy Policy.


We regularly review our compliance with our Privacy Policy. When we receive formal written complaints, we will contact the person who made the complaint to follow up. We work with the appropriate regulatory authorities, including local data protection authorities, to resolve any complaints regarding the transfer of personal data that we cannot resolve with our users directly.


Our Privacy Policy may change from time to time. We will post any privacy policy changes on this page and, if the changes are significant, we will provide a more prominent notice (including, for certain services, email notification of privacy policy changes). We will also keep prior versions of this Privacy Policy in an archive.
