Privacy Policy

Last Updated February 10, 2023

TransferChain was founded on the premise of impregnable privacy and security for the cloud. Our mission is to provide a privacy and security enhancing cloud solution that is unrivaled within the industry.

TransferChain prioritizes privacy in the design, architecture and operation of its products and services. We respect and understand the importance of your privacy and are therefore committed to extending complete protection to the personal information of our customers who use our products and services. Ensuring complete transparency in our practices for using and storing any data is our number one priority.

Legal Framework

This Privacy Policy (this “Policy”) has been prepared by TransferChain AG (“TransferChain” or “We”) having its principal address at Lättichstrasse 6, 6340 Baar, Switzerland.

In line with our commitment towards maximum privacy and transparency, we prepared this Privacy Policy that covers any data you choose to provide to us through the usage of TransferChain Platforms. For the processing of personal data received in connection with career opportunities at TransferChain and the hiring process, please see Privacy Policy for Prospective Employees here.

Capitalized terms used in this Policy but not defined separately shall have the meanings assigned to them in TransferChain’s Terms of Use.

1. Information You Provide

Our overarching objective is to collect as little user information (including personal data) as possible in order to provide a completely private user experience when using our Services. Nevertheless, Your content (including, but not limited to audio, visual and video works and alphanumeric figures and signs) can never be accessed or used to identify any individual.

Personal data processing is limited to the following:

i. Account Information (“Personal Data”)

  • Email Address. In cases where, You choose to register for our products or services on TransferChain with the email option, and/or You volunteer to participate in the beta testing of new applications and/or features, and/or You contact the TransferChain Support Team, and/or You choose to subscribe to our email newsletter, we will be receiving Your email address. However, even if You provide Your email address directly to us, TransferChain is not capable of associating an email address with customers’ content (including, but not limited to audio, visual and video works and alphanumeric figures and signs) uploaded to TransferChain's blockchain based end-to-end encrypted platform, in any way.
  • Performance Information. In order to provide our Services in accordance with our contractual relationship (like the information we need regarding the amount of Your storage), we process activity usage of the Services. Examples include: the size information of the stored content, the amount of transferred content etc. This is solely done for the purpose of providing the necessary account size limits (e.g. 1 TB of storage).
  • Payment Data. If You upgrade Your account to one of our paid offers, You may, depending on Your preferred method of payment, need to provide certain payment and billing information via our third-party secure payment processor (Stripe, Inc). In that regard, please also see Stripe Inc.’s Privacy Policy here. If You delete Your account, we will also wipe Your Stripe profile.

ii. Content Uploaded by You (“Content”)

This is the content (including, but not limited to audio, visual and video works and alphanumeric figures and signs) our customers upload to our systems for the use of services provided by TransferChain. We maintain the confidentiality and accessibility of Content uploaded to our blockchain based distributed cloud systems, through an end-to-end encryption of each file with encryption keys that are generated, derived, encrypted entirely on the client-side, splitting each file into pieces on the client-side, and distributing pieces to the safest providers around the world, while utilizing our blockchain with the user and file authentication and authorization. As a result, any data that is uploaded to TransferChain can only be accessed by You and the intended recipients.

We would like to once again make it very clear that TransferChain acts as a data controller only with respect to the Personal Data and it has no access to and capability to access and/or process Content. Hence, it is of crucial importance that TransferChain should not be considered a data controller related to Content.

iii. De-Identified Website Analytics

We do not use cookies. No personally identifiable information (PII) is collected, and absolutely no cookies are implemented. TransferChain uses privacy-preserving Fathom Analytics on marketing websites to analyze our website performance anonymously. We don’t know who each visitor individually is when they browse our website.

All Content is only stored by TransferChain until deleted by the user. Once the Content is deleted from TransferChain Platform, it cannot be restored.

The collection, use, and disclosure of Your information will be subject to the privacy policies of such third-parties, and not this Privacy Policy. We urge You to read the privacy and security policies of third parties.
