We attach great importance to the protection of your personal data and take great care to ensure compliance with the protective provisions relating to privacy and the processing of personal data, in particular European Regulation n°2016/679 of 26 April 2016 on the protection of individuals with regard to the processing of personal data and on the free movement of such data and Law n°78-17 of 6 January 1978, known as the "Data Protection Act", as amended in 2018 (the "Legislation in Force").
We invite you to carefully read this privacy policy (the "Policy"), which contains important information on how we collect, use and communicate some of your personal data that you send to us in order to meet your needs but also to optimise and improve the quality of the services we offer you.
For the purposes of these Terms of Use, "you", "your" or "the User" means the natural person whose personal data is collected for processing hereunder and who is a "data subject" within the meaning of the Applicable Law, as defined below :
"User Account" means the account created by the User on the Solution enabling him/her to access the Service.
1. Who are we?
The Hyperline solution (the "Solution"), available at the URL https://app.hyperline.co, which enables its users to run subscriptions billing for their SaaS product (the "Service"), as well as the showcase website available at the URL www.hyperline.co (the "Showcase Website"), are provided to you by the company Hyperline, a simplified joint stock company with a capital of €1,528.49, registered with the Paris Trade and Companies Register under no. 909 894 305, with its registered office at 38 rue René Boulanger, 75010 Paris ("we", "us" or "our").
You can contact our Data Protection Officer at the following email address: support@hyperline.co
When you visit the Showcase Website, for the purpose of informing you about the Solution and the Service, we act as a "data controller" within the meaning of the Legislation in force.
In the context of your use of the Service through the Solution, we are also acting as a "data controller" within the meaning of the Legislation in force.
2. Personal data collected
2.1 Information provided by the User
When you use the Solution or browse the Showcase Website, some of your personal data such as your identification data (name, first name, gender, date of birth), your contact details (email address, postcode), your IP address, your location data, and your browsing history on the Solution or the Showcase Website may be processed. We also reserve the right to keep an archive of all contacts you make with us.
When you use the chat assistant on the Showcase Website, we process the messages you write and, if you choose to give it, your email address (see section 2.5).
2.2 Information automatically collected
We may monitor your use of the Showcase Website, the Service and the Solution through cookies and other similar tracking devices. For example, we may track the number of times you use the Showcase Website, the Service or the Solution, the data traffic on the Solution, your IP address, your location data and your browsing history. This information helps us to determine the profile of our users and allows us to establish statistics, traffic volumes and use of the various elements of the Solution and the Showcase Website in order to improve their ergonomics and interest.
On the Showcase Website, we do not seek to know who you are unless you tell us (for example by giving your email address in a form or in the chat assistant). We do use pseudonymous identifiers, such as a browser identifier set by our analytics tool, which let us recognise the same browser across visits without knowing your name. From your IP address, we also identify the company or organisation from whose network you are browsing (its name, website, industry and size), when that network belongs to a company. These identifiers and the company identified may be linked to your visits and to your conversations with the chat assistant, so that our sales team can follow up with the companies interested in our services. For more information on the use of cookies, please see the dedicated section below.
2.3 Information provided by third parties
As part of the Services, we may receive information about you from third parties who hold personal data about you that you have indicated to us, including third party payroll, payment or other providers connected to the Solution. This information will be automatically added to the information collected about you, in order to best meet your needs and to optimize and improve the quality of the services we offer you.
2.4 Using data from connected Google Services
If we have received your personal data because you have chosen to Sign in with Google, we will process your personal data to perform any contract we have entered into with your employer or in relation to any steps we take at the request of your employer prior to entering into a contract. In particular, this includes providing you with access to the Hyperline application.
Hyperline provides a billing and revenue management application aimed at business customers. If we have received personal data because you have chosen to connect your Google Drive and/or your Gmail account, we will collect your data from this service in order to enhance the billing, contract, and customer document management experience and improve your productivity when using the Hyperline application. In particular, this includes access to your Google user data from within the Hyperline application where you can view your data in the relevant context of a billing software application and manage your professional relationships.
Additional Limits on Use of Your Google User Data
Notwithstanding anything else in this Privacy Policy, if you provide us with access to data from connected Google services, our use of that data will be subject to the additional restrictions set out below. For the avoidance of doubt, we process data received from connected Google services solely in the capacity of a processor on your behalf, and not as a controller:
- We will only use access to data from a connected Google Service to provide our Hyperline web billing and revenue management Plateform on a read-only basis, allowing users to read and view relevant emails, billing-related communications, and view associated Google Drive files or contracts. Hyperline will not write, modify, or delete any data, emails, or files within your connected Gmail or Google Drive services. Furthermore, our use of data is limited to providing or improving user-facing features that are prominent in the requesting application's user interface.
- We will not transfer this data to others unless doing so is necessary to provide and improve features that are prominent in the user interface, comply with applicable law, or as part of a merger, acquisition, or sale of assets.
- We will never use Google User data for serving advertisements, including retargeting, personalized, or interest-based advertising.
- We will not allow humans to read this data unless we have your affirmative agreement for specific messages, doing so is necessary for security purposes such as investigating abuse, to comply with applicable law, or for our internal operations and even then, only when the data have been aggregated and anonymized.
- Hyperline's use and transfer to any other app of information received from Google APIs will adhere to Google API Services User Data Policy, including the Limited Use requirements.

- a pseudonymous browser identifier, a hashed form of your IP address (your IP address itself is not stored), the country and network you connect from, and the company identified from your IP address where applicable;
- your email address and the name of your company, only if you choose to give them in the conversation;
- a summary of your needs drawn from the conversation (such as your company's size, pricing model or the tools you use), so that our team can follow up appropriately.
Your messages are sent to the providers listed in section 5 to generate the answers. Please do not share sensitive information in the chat.
