For translating Tutanota we use Phrase. This is a great tool specially designed for software translation from a start-up in Hamburg, Germany.

We hope that you will enjoy using Tutanota in your local language even better.

If you want to protect your privacy even further, read our tips on how to leave Google behind.

Tutanota language

You can use Tutanota in more than 30 languages already. The language of the Tutanota email client and apps is automatically defined by your browser or system settings. You can also switch the language under Settings - Appearance in your mail client.

The language of the Tutanota website can be switched by clicking on the world symbol in the lower right corner.

Translation instructions

If you already are a translator, please follow the instructions below.

Once you have translated a key, please proofread it and then make sure to also verify your translation. Only by verifying it, you will be able to see changes made to the original English version. As Tutanota grows in functionality, we are adding texts continuously, so please check in regularly.

Styleguide

During translation please try to keep the length of the text similar to the existing English and German versions. This will make the integration much easier. Also please make sure that you leave the placeholders in their predetermined position.

In the translation project 'Tutanota', which is for your Tutanota mail client, we have only one placeholder (while n can be any given number): {n}. This placeholder needs to remain as it is and must not be changed.

In the translation project 'Website', we use markdown for formatting the texts on the website. Please make sure to leave any markdown symbols as they are. You can remember this easily by following these simple instructions:

Copy the English text into your translation. Only translate texts. These texts can also be within square brackets [ ] or within single or double stars **. Make sure that the markdown symbols from the English version match your translated texts exactly. Make sure NOT to translate placeholders. This is texts within curly brackets within standard brackets ({ }).

These placeholders lead to links or images and must remain exactly as they are in the translation.

From time to time, we need to update keys as Tutanota evolves over time as well. These keys will then become 'unverified' in your language version to indicate that the key needs to be adapted. To view the changes in the English original, simply click on 'View changes' while updating the translation key in your language.

If you have questions about this, please get in touch via email or meet us on Reddit.
