Terms of Service

Last updated: November 9, 2026

Who provides the app

Stille Post is provided by:

Deutsche Gesellschaft für Taubblindheit gGmbH
Hollestraße 1, 45127 Essen, Germany
Email: info@gesellschaft-taubblindheit.de

These terms apply to the use of the app and of our server. By using them, you agree to these terms.

Children under 16 may use the app and our server only with the consent of their parents or guardians.

What the app is

Stille Post turns spoken language into text. This happens on your device or, if you turn that on, over a server. If you want, the app translates the text into another language and reads typed messages aloud with a voice of your device.

The recognized text can contain errors. Words can be missing, wrong, or assigned to the wrong person. The translation can be incorrect as well. Check the correctness of important content before relying on it. In emergencies and for medical, legal or financial decisions, do not rely on the transcript alone.

The app is free of charge. These terms govern the use of the app and the server.

Recording other people

The app records what other people say. The spoken word is protected by law.

Tell everyone present that the app is writing down what they say.

You are responsible for abiding by this rule. We cannot check whom you record.

When using “Remember voice”, the app stores a voiceprint of a person on your device. Using that, the app recognizes the person again later and assigns a saved speaker label. Only remember a voice if the person explicitly agrees. Delete the voice if the person asks you to.

Saving, copying, and passing on

Before you save or copy a transcript, obtain the consent of everyone who participated in the conversation. Having told them that the app is recording is not enough.

The same applies before you pass a transcript on to others.

Our server

You can configure the app to send the audio to a server for transcription. The preset is our server at stille-post-server.almost-senseless.tech. With translation on, the server also translates the text. What the server receives is described in the Privacy Policy.

The app signs in to the server by itself. To do that it creates a random identifier on your device. These credentials are private. Do not pass them on.

We strive for high availability of the server. We cannot guarantee it, however. We may change, limit or discontinue the service at any time. Local transcription is not affected by this.

Do not misuse the server. This includes unlawful content, attacks on the server and deliberate overload. In case of misuse we may block your access to the server.

You can enter a different server. Its operator's terms apply to its use.

Processing on your behalf

When you transcribe audio through our server, we process the audio, the recognized text and the translation on your behalf. This is processing under Art. 28 GDPR. This section serves as the processing agreement. It applies in cases where the GDPR applies to your use.

We turn the audio into text and translate it if you wish. We process the data only for that purpose. We only process it during the recording and store neither audio nor text persistently. We do not use the data for our own purposes. For example, we do not train machine learning models with it.

The data concerns you and every person whose voice the app records. The audio may contain any kind of information. This includes specially protected information under Art. 9 GDPR.

Your settings in the app serve as our instructions: transcription language and, optionally, whether to translate and the target language for translation. We process the data only according to these instructions. If a law obliges us to do something else, we tell you beforehand, as far as the law permits.

Everyone with access to the server on our side is bound to confidentiality. The connection to the server is encrypted. We protect the server with technical and organizational measures under Art. 32 GDPR.

Our sub-processor is STRATO GmbH. STRATO runs the server's hardware in Germany. By accepting our Terms of Service, you agree to this sub-processing. We use further sub-processors only after informing you first. You may then object.

Should people wish to exercise their rights under the GDPR, we will provide you with support. We will also support you if a data breach occurs. If a breach affects your data, we inform you without undue delay on our website. We provide you with the information you need to demonstrate compliance. We allow you, or an auditor you appoint, to carry out audits of our service.

We do not store audio or text. They are therefore deleted at the end of every recording.

Liability

We provide the app and the server free of charge. We do not guarantee that the service is suitable for commercial, legal or medical purposes.

We do not warrant that the recognized or translated text is correct or complete or that the server is reachable.

Changes

We may change these terms, for example when the app gains new features. A new version is shown after the app is updated. We then ask for your consent again.

Law

German law applies. Mandatory consumer rights of your place of residence remain unaffected.
