Privacy Policy

Last updated: 18 March 2019


We take the protection of our users (“User/you/your”) personal data very seriously and strictly comply with applicable data protection laws and regulations. In our privacy policy below (“Privacy Policy”) we provide you with an overview of what data we collect for what purpose and how we ensure the protection of the data.

The controller is Gaiwan GmbH, c/o Arne Brasseur, Kinzigstr. 26, 10247 Berlin/Germany (“we/us/our”).

In general Lambda Island aims to only store, process, or share the minimum information necessary. The less we know about you, the better. We do need to know certain things in order to provide services, communicate with you, or meet legal requirements. In this document you can find a complete overview of what we collect and store.

Information gathering and usage

The use of is possible without sharing any personal data. Free content like blog posts, “freebie” episodes, or ebook guides can be perused anonymously. Other content and services require the creating of a Lambda Island account. We store the email address and username of Lambda Island account holders. We do not require a username to correspond with your real name.

Lambda Island accounts are not publicly visible, but public interactions on the site such as leaving comments are visible together with your username.

When you buy products or services from us we ask for the information needed to create an invoice. In this case we store your name, address, EU VAT registration ID, and the products or services you purchased.

Your Data

Lambda Island uses third-party vendors and hosting partners to provide the necessary hardware, software, networking, storage, and related technology required to run Lambda Island. You retain all rights to your data; we will never share your personal data with a third-party without your prior authorization, and we will never sell data to third-parties. We transfer data with third-parties necessary to our ability to provide our services, all of whom are GDPR-compliant and provide the necessary safeguards required if they are outside of the EU.

Third parties that we work with currently include

This list is not meant to be exhaustive, and other GDPR compliant services may be added in the future without notice.

Your rights

Right of access

You have the right to be informed at any time and free of charge about the personal data stored about you.

Right to rectification

You have the right to rectify inaccurate personal data about you. Taking into account the purposes of the processing, you have the right to have incomplete personal data completed (for example, by providing an additional statement).

Right to be forgotten

You have the right to have us delete any personal data concerning you that we store. We have the obligation to erase your personal data without undue delay where one of the following grounds applies, as long as the processing is not necessary:

Right to data portability

You have the right to ask for and receive the personal data we store about you in a structured, commonly used and machine-readable format. You also have the right to transfer this data to another controller without hindrance by the controller to whom the personal data have been provided, provided that the processing is based on a consent or on a contract to which the data subject is a party and that the processing is carried out by means of automated procedures.

Furthermore, in exercising your right to data portability, you have the right to have personal data transmitted directly from one controller to another where technically feasible — and when doing so does not affect the rights and freedoms of others.

You have the right to withdraw your consent regarding the use, processing or transmission of your data at any time in writing or by email to us.

In the event of consent withdrawal, we will no longer process and immediately delete your stored data. This does not apply if we can prove compelling grounds for processing that are worthy of protection and which outweigh your interests, rights and freedoms or in case the processing serves to assert, exercise or defend legal claims. For example, we will continue to use data if it is still necessary for tax purposes.

Duration of Storage

We store your data as long as your account is active, or as long as it is needed for legal or tax filing purposes.
