Open source

Open source describes software which uses a source code that the broad public can view, modify and use. Open source software can be used for free in most cases, however many commercial tools are also based on open source software. Therefore, it is not always easy to distinguish between programmes which are open source and those which are not. We have defined three criteria to categorise tools in the table above as open source:

  1. The tool was programmed based mostly on open source code and open source software and is transparent about it.
  2. The tool providers state that their tool is open source.
  3. The tool can be re-programmed, modified and adapted by externals.

Data protection

The column about data protection indicates the degree of data protection granted when using the tool. Data protection was evaluated according to the following criteria:

  1. Are the servers located in Europe, outside Europe or is their location not indicated?
  2. Is the data protection declaration clearly understandable and easy to find for users? Can settings be changed easily?
  3. Have there been any data protection scandals about the tool or the organisation providing the tool over the last years?
  4. Is it part of the organisation’s free business model to commercially generate user data?
  5. Who owns the data and can users decide whether their data is locally stored on their own servers?
  6. Is it transparent and clear where data is stored and who can access it?
  7. Is there an option for end-to-end encryption?
  8. What are the default privacy settings?

We do not prioritise any questions. If you have feedback or questions regarding the evaluation, please contact us via
