We will NEVER sell your personal data to anyone.

Quaderno carries out all processing operations in strict compliance with European privacy laws and never sells personal data to anyone. You are in control of your personal information at all times.

Quaderno values your privacy and strives for its services to be safe and enjoyable for everyone. This policy sets out and explains how Quaderno collects and processes personal data, the purposes for processing and how we protect it.

Quaderno is committed to the Internet and to its users. This is why one of its main commitments is to provide the most secure and confidential service possible, ensuring the privacy of users' communications and personal data.

This policy is split into sections. For your convenience, the link to each of those sections is as follows:

Why do we process personal data?

This policy applies when Quaderno process your personal data for various purposes when you interact with us, such as:

  • Create and facilitate accounts for users of our services.
  • Improve and develop the quality, functionality and user experience of our products and sites.
  • Offer customer support for our products and services.
  • Detect, mitigate and prevent security threats and abuse, and perform maintenance, and debugging.
  • Manage and send marketing preferences and content.
  • Create interest profiles in order to promote relevant products and services (profiling).

What personal data do we process?

Our guiding principle is to collect only what we need. Here’s what that means in practice:

Identity and access

When you sign up for Quaderno, we ask for identifying information such as your name, email address, and maybe a company name. That’s so you can personalize your new account, and we can send you product updates and other essential information. We may also send you optional surveys from time to time to help us understand how you use our products and to make improvements. With your consent, we will send you our newsletter and other updates. We sometimes also give you the option to add a profile picture that displays in our products.

We’ll never sell your personal information to third parties, and we won’t use your name or company in marketing statements without your permission either.

Billing information

If you sign up for a paid Quaderno product, you will be asked to provide your payment information and billing address. Credit card information is submitted directly to our payment processor and doesn’t hit Quaderno servers. We store a record of the payment transaction for purposes of account history, invoicing, and billing support. We store your billing address so we can charge you for service, calculate any sales tax due, send you invoices, and detect fraudulent credit card transactions.

Product interactions

We store on our servers the content that you upload, receive or maintain in your Quaderno account. This is so you can use our products as intended, for example, to create invoices. We keep this content as long as your account is active. If you delete your account, we’ll delete the content within 6 months. For such data we are the Processor and base our processing upon the agreement with the customer (the Controller).

General geolocation data

For most of our products, we log the full IP address used to sign up a product account and retain that for use in mitigating future spammy signups. We also log all account access by full IP address for security and fraud prevention purposes, and we keep this login data for as long as your product account is active.

Website interactions

We collect information about your browsing activity for analytics and statistical purposes such as conversion rate testing and experimenting with new product designs. This includes, for example, your browser and operating system versions, your IP address, which web pages you visited and how long they took to load, and which website referred you to us. If you have an account and are signed in, these web analytics data are tied to your IP address and user account until your account is no longer active. The web analytics we use are described further in our Cookies Policy page.

Anti-bot assessments

We use CAPTCHA across our applications to mitigate brute force logins and as a means of spam protection. We have a legitimate interest in protecting our apps and the broader Internet community from credential stuffing attacks and spam. When you log into your Quaderno account, the CAPTCHA service evaluates various information (e.g., IP address, how long the visitor has been on the app, mouse movements) to try to detect if the activity is from an automated program instead of a human. The CAPTCHA service then provides Quaderno with the spam score results; we do not have access to the evaluated information.

Advertising and cookies

Quaderno runs contextual ads on various third-party platforms such as Google, Facebook, and LinkedIn. Users who click on one of our ads will be sent to the Quaderno marketing site. Where permissible under law, we may load an ad-company script on their browsers that sets a third-party cookie and sends information to the ad network to enable evaluation of the effectiveness of our ads, e.g., which ad they clicked and which keyword triggered the ad, and whether they performed certain actions such as clicking a button or submitting a form.

We also use persistent first-party cookies and some third-party cookies to store certain preferences, make it easier for you to use our applications, and perform A/B testing as well as support some analytics.

A cookie is a piece of text stored by your browser. It may help remember login information and site preferences. It might also collect information such as your browser type, operating system, web pages visited, duration of visit, content viewed, and other click-stream data. You can adjust cookie retention settings and accept or block individual cookies in your browser settings, although our apps won’t work and other aspects of our service may not function properly if you turn cookies off.

You have more information about the cookies we use in Quaderno in our Cookies Policy page.

Voluntary correspondence

When you email Quaderno with a question or to ask for help, we keep that correspondence, including your email address, so that we have a history of past correspondence to reference if you reach out in the future.

We also store information you may volunteer, for example, written responses to surveys. If you agree to a customer interview, we may ask for your permission to record the conversation for future reference or use. We will only do so with your express consent.

For the purposes mentioned in the section “Why we process personal data”, Quaderno does not process any sensitive personal data about you.

How is personal data collected?

In general, Quaderno collects personal data directly from you. If you purchase Quaderno’s products or services via a partner company, we may collect information about you from the partner company.

Quaderno will also use cookies and other tracking technologies when you use our services, in order to optimize your experience of Quaderno and our products. For more info about the cookies Quaderno makes use of, please visit our Cookies Policy page.

Marketing and profiling

When you interact with Quaderno e.g. by visiting our websites, downloading content, attending webinars, and as part of using our services, Quaderno will be processing your personal data based on legitimate interest. One of our legitimate interests is the processing of personal data for direct marketing purposes.

Quaderno uses your personal data to provide relevant content to you through direct marketing on social media platforms and emails, webpages or in a service, based on your preferences. The personal data processed are aggregated details about you such as IP address, interests (where you have clicked, etc.), username and device. This is done through technologies like cookies and is called profiling. Quaderno will also be able to combine this information with information about the customer relationship we may have with your company.

The purpose of the profiling is to deliver customized marketing to you, improve your user experience with our services / websites and deliver products that our customers are satisfied with. Quaderno’s services are generally used as tools for work-related purposes, and your behavior in these tools says little about your personal life. No sensitive data is processed. Your personal data is therefore processed from a business perspective in a way that we believe does not conflict with your freedoms and rights as an individual.

Quaderno uses email as a tool to communicate marketing, however only if you have consented in accordance with national marketing legislation (if needed). If you have consented, you will always have the possibility to opt out as described below, or when you receive an email containing marketing.

Right to opt-out of marketing communications

You have the right to opt out of receiving marketing communications from Quaderno and being subject to profiling. You can do this by either:

  • Following the instructions for opt-out in the relevant marketing communication
  • Contacting us via e-mail at

Please note that even if you opt out from receiving marketing communications, you may still receive administrative communications from Quaderno, such as invoices and notifications necessary to manage your account or the services provided by us.


We encourage you to review this policy regularly. If we make significant changes to it that materially alter our privacy practices, we may also notify you by email prior to the changes taking effect. You hereby agree that this shall constitute adequate notice in this regard.

All changes to this policy automatically take effect on the sooner of the day you visit our sites or use our services, or 30 calendar days after they are initially posted on this website.
