Privacy Policy

Data Protection Policy

This data protection policy (hereinafter: “Privacy Policy”) informs you of our privacy practices at our general company website under but also for the features and services we are offering during and after the on-boarding process at

In summary, as explained further detail at, we endeavour to empower you with self-sovereign identity and seamless addition of integrity, authenticity and privacy to any kind of digital service (hereinafter “Vereign Services”) and your associated digital identity account (hereinafter: “Vereign Identity”).

After your successful on-boarding we are providing you at with the central user interface of your Vereign Identity, enabling you to check and edit your identity, individual profiles and stored interaction information (hereinafter: “Vereign Dashboard”) .

We will also offer you to install certain plug-ins for other applications and services starting with - but not limited to your Microsoft Office 365, Gmail account, LibreOffice and Roundcube based email web clients (hereinafter collectively: “Vereign Extensions”). Additional Vereign Extensions will be gradually available one after another. In case activated by you such Vereign Extensions will sent data to your Vereign Dashboard. Consequently, Vereign Dashboard will show you any respective data and interactions- you choose to use Vereign Extensions for.

I. Name and contact details of the controller

Vereign AG

For questions with regard to this Privacy Policy or other concerns in this subject area, you may contact our data protection team directly via:


II. General information

At Vereign we respect your personal data. Naturally, our data protection practice complies with applicable law including but not limited to the Swiss Data Protection Act (“Swiss DPA”) and its Ordinance (“Swiss DPO”). Also we are fully compliant with the General Data Protection Regulations (“GDPR”) of the European Union and its local adaptations including but not limited to the German Federal Data Protection Act (“Bundesdatenschutzgesetz”).

As a matter of principle, we collect and use personal data as much as necessary to provide our services requested by you (Art. 6 para. 1 Lit. b GDPR). A notable exception applies where a contractual basis is not apparent and the processing of personal data can only be authorised via your explicit consent (Art. 6 para. 1 Lit. a GDPR). In such a situation we will explain to you the exact purposes and consequences of the concerned data processing and you may at any time retrieve your consent given to us. In no event will we sell your personal data to any third party for any business or political agenda.


III. Allowed purposes for collecting and processing your personal data

Our collection and processing of your personal data under this Privacy Policy is limited to the extent necessary to fulfil the following rather apparent purposes:


1. Contact Forms and Job Offerings

On our website we provide you with:

a) Contact forms like “count me in” button

We are providing you with the opportunity to get in touch with our team and you may send us a respective email, asking us to keep you informed about our projects and related events and other announcements. In particular we offer you a “count me in” button, which provides your chosen mail client with our contact email address In case you explain to us in such an email, you would like to participate in our projects or at least you would like to be informed about further developments, events and other news, we will include your provided email address, in an email list we use in case of the purposes just outlined above.

After you gave us your contact details (/email address), you may at any time retract your consent and object to any further usage of your emails address for the mentioned purposes. In order exercise such a right to object future usage of your email address, please just write us another email to and we will delete your email address from our list without undue delay.

b) Applications for advertised job offerings

On our website we may also provide you with the opportunity to apply for advertised job positions, within our company group. In case you choose to apply to such a particular job offering, we will use your name, contact details and all other provided information exclusively for the relevant application process. In case you choose to opt for “Send me further details about other vacancies” we will also use your contact details and all other provided information to keep you informed about future job positions, even after the job offering you applied to has been filled. But of course, you may retract your consent any time (see also below: VII. Rights of the data subject).


2. Creating your Vereign Identity

You may choose to create a Vereign Identity at, in this case we will use account information (provided by you during the on-boarding, including but not limited to your email address or telephone number) for the purposes of creating and validating your Vereign Identity. In particular, as explained during the on-boarding process, you will receive an email and/or text message in order to verify the provided contact details by means of a unique code.

At the end of the Vereign Identity creation, you will be asked to agree to detailed terms of use (hereinafter “Terms and Conditions). However, in the case of inconsistencies between these Terms and Conditions and this Privacy Policy, the latter shall prevail. Or, in other words: nothing in our Terms and Conditions shall challenge our commitments given to you in this Privacy Policy.


3. Maintaining your Vereign Identity

Except as explained in this Privacy Policy, we will process and transfer you data only in case you trigger such a process and transfer. In case you attach particular parts of your Vereign Identity (your chosen profile) to an email or document the included data will be transferred to the recipient of your choice. By doing so you also establish a live connection between this recipient and your chosen profile (claims of your identity). Consequently when you choose to update shared details of your Vereign Identity, this update will be automatically shared as an update with the recipient of your choice.

In case of an account recovery processes has been triggered, we will use your provided contact details in order to safeguard that the processes has been triggered by you and to guide you through the necessary steps. Furthermore, in order to provide you with an audit-log of your Vereign Identity we collect technical information, as shown to you in your Vereign Dashboard tab “Activity”. This audit log provides you with tamper-proof evidence of all your “vereigned” actions. Data stored for this security feature is:

- Internet Protocol Address (IP address)

- Universally Unique Identifier of your used computer device (“UUID”)

- The category of your activity (e.g. login into your Vereign Dashboard, creation of profiles and claims just as well as sending emails or signing documents)

- Time and Date of your activity

- Blockchain Hashes (that have been written on a blockchain, see clause II no. 4 below)



4. Blockchain hashes

In certain events while using Vereign Services and as part of your audit log (as described in the previous section under clause II no. 3 above) a hash function is mathematically obfuscating data categories (hereinafter: “Input Data”), and this hash is subsequently written to a public Blockchain network administrated by Æternity Establishment.

In short, such a cryptographic hash function and subsequent transfer shall allow you (and your chosen recipients) to verify the authenticity and integrity of sent and received Input Data with the aid of the Blockchain hash. As long as a copy of the Input Data exists, the Blockchain hash will provide evidence that this copy of data is authentic and has not been altered (after being hashed). By itself the Blockchain hash is just a seemingly random sequence of characters identified by an abstract one time transaction identifier.

All activities where Input Data is hashed, are shown to you in detail under the tab “Activity” in your Vereign Dashboard. Such events are: Login into your Vereign Dashboard, creation of profiles and claims just as well as sending emails or signing documents. The data categories of the Input Data are shown to you in connection with the respective activity and may deviate from event to event. The following data categories are currently used for the Input Data:

- Date/time

- Device name

- Device IP

- Device UUID

- User UUID

- Claim Name

- Claim Value

- Recipient list

- Profile name

- Profile UUID

- Thread name

- Email ID

- Document name

Given the complexity of this Input Data the resulting Blockchain hash is practicable infeasible to invert, without having access to the original Input Data anyway (e.g. your vereigned email, profile or document). We even add another layer of random values to further increase the unlikeliness that a powerful computer could “brute force” the hash and thereby understand what information had been contained in the Input Data.

That also means as soon as you chose to erase the original Input Data (e.g. erase you Vereign Identity and all associated data) the abstract hash on the Blockchain will have no counterpart and will consequently not represent personal data anymore. Thereby it is technically feasible to separate your personal information from the abstract hash, leaving the abstract hash on the Blockchain without relevance for you and your personal information.

But please note, in case you have chosen to share your personal data via Vereign Services with other recipients these recipients will still have access to the confirmational value of the stored hash – due to the fact that they are still in possession of the Input Data (e.g. your email, profile or document you have chosen to share with this recipient). Same applies, in case your recipients share your data with others. This even applies in case a recipient forwards your information to others without your consent. However please understand, such a breach of confidence would be a matter between you and your recipients of communication.


5. Vereign Extensions

In case you choose to install and activate any of our Vereign Extensions any of your “vereigned” interactions will be sent to our servers and will be shown in your Vereign Dashboard accordingly.

What exact data will be transferred depends on the chosen Vereign Extension, therefore individual Vereign Extensions may be covered by dedicated privacy policies. However, nothing in our additional privacy policies regarding Vereign Extensions (if any) shall challenge our commitments given to you in this Privacy Policy. In the case of inconsistencies with such additional privacy policies, this Privacy Policy shall prevail.

On the other hand any activated Vereign Extensions will, after login verification, have access to your profiles as you have set up in Vereign Dashboard.


6. Keeping you up to date

As long as you choose to continue to use our Vereign Services we will keep you informed about our software development and additional Vereign Extensions. Also we may may ask about your user experience and other relevant feedback. For these reasons, we might reach out to you by using the contact details you choose to provide during your creation of a Vereign Identity.


7. Customer support and your Feedback

Also we provide you with the opportunity to give us your feedback, e.g. via a quick feedback function in your Vereign Dashboard (upper right corner in your Vereign Dashboard). In case you choose to address a certain issue or question via this functionality, we will automatically send your name, email address and phone number along with your feedback. This contact information has the sole purpose to help our support team to answer any question or mitigate your concern. After the support team has addressed your issue, your contact information and your feedback will be archived for 12 months - afterwards this information will either be anonymised or erased in its entirety.

Regardless of the channel you use to provide us with your feedback, as an open source company your collaboration and engagement is crucial for us. We need interested participants to test and try out the Vereign Services and provide us with feedback. If you choose to engage in such software testing and providing us with feedback, in the spirit of the open source community, this is also a main reason you are providing your related personal data to us and this purpose forms our legal relationship in the meaning of Art. 6 para. 1 Lit. b GDPR. We commit ourselves to exclusively use your related personal data for this purpose of testing and improving Vereign Services.


8. Secure Payment Gateway

The Payment Card Industry Data Security Standard (“PCI DSS”) is a set of security standards designed to ensure that all companies that accept, process, store or transmit credit card information maintain a secure environment.

In order to provide you with a such a secure, PCI DSS compliant, payment option we are using Strip Inc., as a payment gateway provider. As soon as you are choosing to provide us with your payment details in the billing section of your Vereign Dashboard, Stripe Inc, is using cookies for the purposes of user authentication, fraud detection, fraud prevention. A full disclosure of Stripe Inc. use of cookies, including persistent cookies, is documented online at Placing these Stripe cookies and the subsequent data processing by Stripe Inc. is an essential part of a secure and compliant payment operation and we cannot offer any service that depends on your payments if these cookies are disabled.


9. IP-Addresses and webserver log files

In order to allow for the requested website of Vereign Dashboard to be displayed in your browser, we need to temporarily store and process your IP address. The legal basis for this temporal storage of personal data is Art. 6 para. 1 Lit. f of the GDPR.

After your individual session has ended, your IP address will be saved anonymously in log files of our web server. The information in our log files includes:

- the exact pages you accessed in our URL(s)

- date and time of your request

- the name of your telecommunication provider

- your browser type

- your operating system

- your anonymised IP address

We will use this non-personal data exclusively to safeguard the functionality of the website. Such log files are highly relevant for optimising our webpage and to safeguard the security of our information technology systems.


10. Cookies and the Matomo web analysis service

We use “cookies” on our internet pages. Cookies are text files stored on your computer that help increase the ease of use, efficacy and safety of our internet service.

First and foremost the temporary use of cookies in the form so called “session cookies” is technically mandatory in order to allow to display the requested website in your Browser accurately. Such cookies will be erased after you individual session (after you have closed the browser tab displaying our website).

Also during payment processes, we need to use cookies of our payment gateway provider to provide you with a secure and compliant payment option (see above clause II no. 8 for further information).   

In case you provide us with your respective consent in our “cookie banner”, we will additionally place so called “tracking cookies” in your browser and we will analyse the data stored by such tracking cookies on your machine using “Matomo” web analysis software. Such cookies will remain in your browser for longer periods than the individual session. The purpose of this data processing is to improve our internet sites and for this we need to understand what function or information proves useful or at least interesting to our visitors. For this purpose, information of usage (generated by the “tracking cookies”) is transferred to our server and stored for respective usage-analysis purposes. But your IP address is already stored in the cookie simply in an anonymised form only, and it is only recorded in this form by our web analysis software so that you remain as anonymous as feasible as an individual user in the context of the analysis. In detail in such “tracking cookies” we store:

  • Anonymised user IP
  • Date and time of access
  • Screen resolution
  • User’s time zone
  • Files downloaded and clicked on
  • Links to external domains (outlink)
  • Page generation speed (how long did it take until the visited page was displayed)
  • Visitor location: country, region, city (geolocation)
  • Browser language
  • User’s browser type

However, if you do not wish to agree to the use of such “tracking cookies” anymore, you can erase them or even prevent their use with a corresponding setting in your browser software. You can also object to the use of data recorded by “tracking cookies” by clicking the following link. In this case, an “opt-out cookie” is placed in your browser, which means that Matomo will not record any session data at all. Important: If you delete your cookies, this means that the opt-out cookie will also be deleted and that you must reactivate it, if necessary. If you do wish to place an opt-out cookie right now, please opt out below.


Matomo Cookie Preference


IV. Interfaces to other Service Providers

In the course of development we will include more and more options for you to enhance your Vereign Identity with other service providers. But it will always be your choice either to use or not to use such third party providers and to link your Vereign Identity to such service providers.

While personalising your Vereign Identity you may choose to add profile pictures under During this process we provide you with an option to include your avatar pictures as uploaded to a non-affiliated third party provider “Gravatar” (, In case you choose this option we will send the hash of your email address via an encrypted connection to this third party provider. In the event there is a user account matching the hashed email, Gravatar will provide your avatar picture to your Vereign Identity.


V. Data erasure and storage period

At any time after you have entrusted us with your personal data, e.g. to create and maintain a Vereign Identity, you may object to any further usage of your personal data (including but not limited to your email address or telephone number or any other personal data you have chosen to include in a profile or recorded interaction in the dashboard application). In order to exercise the right to object future usage of personal data, please just write us an email to indicating your request and we will delete your account will be blocked within two weeks after we have received your authenticated mail.

In case you choose to write us an unauthenticated mail (not using the Vereign Services), we may ask you to provide us with sufficient evidence that you are indeed entitled to the Vereign Identity you claim to represent.

As a safety feature, after receiving such a request for deletion, we will reach out to you through any of the communication data you have choose to provide to your Vereign Identity. In case you indeed wanted to erase your Vereign Identity, these communication serve as confirmation of receipt of your requested deletion. In case you did not intent to delete your Vereign Identity, and any associated data, please reach out to us using

For a transition period of two months after a request for deletion we will keep your stored data (identity claims, emails and documents), and you may reactivate your Vereign Identity during this period, for such an reactivation please reach out by using But after this transition period of two months your data will be erased in a non recoverable way.  

Without such a specific request your personal data will be erased as soon as the defined purpose of storing the data ceases to apply.

However, please note there may be explicit legal obligations or at least recognised interests of our company in line with EU GDPR and other applicable legislation to keep some of your personal data stored (or at least recoverable) for a certain retention period, even after the original purpose of storing your data ceases to apply, or you have exercised your right to object further usage of your personal data (Art. 6 para. 1 Lit. c and d GDPR). In such a case, the data will be erased if a storage period stipulated by the aforementioned rules or legitimate interests expires. In particular in case you choose to communicate with another Vereign recipient via Vereign Extensions, these other recipients using Vereign Services will keep a respective copy of your email conversation or exchanged document in their interaction history (as long as they choose to store this information), even after you decided to erase your account and personal data.
