A) Negotiations with clients regarding the conclusion of contract for use of the Application and the provision of a free demo version - those interested in using the Application for the needs of their business may contact OnSinch and enter into negotiations about the terms of the contract. For this purpose, OnSinch processes the following personal data of interested parties: first and last name, e-mail, telephone, organization, job title, ID number, VAT number, invoicing data, account number. The data is processed until the conclusion of the contract or for a period of 1 year from the end of the negotiations, shall the contract not be concluded.

In such case, OnSinch processes data in the scope of first and last name, e-mail, telephone and other data provided by the third party in their inquiries for the purpose of processing such inquiries.

F) Improving the OnSinch communication and push notifications - OnSinch company collects information about the activity of website users, including data obtained using cookies. Based on the collected data, OnSinch monitors statistics regarding the engagement of website users. Each user can change the cookie settings and manage their consent with data collection in their browser settings.

G) Newsletter –OnSinch processes the data of users subscribed to the newsletter in the scope of first and last name and email address, and only if the user has given consent to such processing. The user may revoke the consent at any time free of charge, by sending an email to the contact address of OnSinch or by clicking on the relevant link in the footer of the messages sent.

H) Allowing end users to register to the client’s Application using Facebook and Google tools – to facilitate the login and registration of end users to the client’s Application, the Application enables simplified registration and login of the end user using their existing profile on Facebook or Google services. In order for simplified login to be possible, the end user must actively choose such option and give the Application consent to access public data on the relevant profile and to transfer it to the client. If such consent is granted, OnSinch processes data in the scope of public data on the end user's profile (name and surname, email, profile photo) for the purpose of transferring them to the registration form in the client’s Application. Upon completing the registration, OnSinch does not process personal data as the controller. The client becomes the controller thereof and OnSinch remains mere processor carrying out the operation of storing data in the client's Application.


OnSinch is a processor of personal data collected by individual clients during the course of operating the Application managed by them. Clients are thus controllers of personal data who determine the purposes and means of processing end users' data, while instructing OnSinch to carry out mere operation of storing collected data in the Application.

Under this mechanism, OnSinch does not have access to the content of the stored data and information and cannot influence their scope, content or format. The controller (client) with whom OnSinch has concluded a contract for the processing of personal data is responsible for fulfilling obligations imposed by GDPR on data controllers. OnSinch does not carry out any data processing operations other than the storage operation.

OnSinch has adopted the maximum standard of technical, organizational, security and other measures to prevent unauthorized or accidental access to data, change, destruction, loss or other unauthorized handling thereof.

OnSinch ensures that employees and other persons authorized to process data do so only to the extent and for the purpose of fulfilling the contract concluded with the client, all of this pursuant to applicable legal regulations. OnSinch takes professional care in fulfilling its obligations under the GDPR.

OnSinch, as a processor, may process data collected by the client only for the duration of the obligations arising from the contract for use of the Application or from the contract for the processing of personal data in accordance with GDPR.


Clients, end users and other third parties may voluntarily decide whether or not to provide personal data to OnSinch. However, provision thereof may be necessary for the use of certain services or for the use of OnSinch’s products. For example, it is not possible to allow the client to use the Application without knowledge and processing of his personal data, nor to allow the end user simplified registration without allowing access to his other existing profiles.
