Psychotherapie.com enables you, through encrypted Written Cognitive Psychotherapy (WCP), to pursue intelligent psychotherapeutic self-help known only to two people — you and your psychotherapist. For our encrypted communication, we use AES-256-GCM, the most trusted symmetric encryption standard. AES-256-GCM is the industry standard, employed by banks, governments, and the military. Security depends on the password — choose at least 20 random characters. One key encrypts, the same key decrypts. Encryption and decryption are performed entirely in your browser, regardless of your operating system, via the Web Crypto API, which encrypts and decrypts directly in the browser using AES-GCM. Your data is not stored anywhere. No data leaves your device. No data-breach risk.
Encrypt and decrypt the file we use for communication here. First, select whether you wish to encrypt or decrypt. Then choose the communication file and enter your password. When you press the "Encrypt file" or "Decrypt file" button, you will receive the corresponding encrypted or decrypted file.
The source code is entirely contained in this file — no external dependencies. Encryption standard: AES-256-GCM with PBKDF2 key derivation. No file and no password is transmitted to the server. Encryption is performed exclusively in your browser.
Excerpt from our Privacy Policy
Forget everything you think you know about psychotherapist client confidentiality during psychotherapy. Anyone entering psychotherapy within the public health system today renders themselves vulnerable. The uncomfortable truth is: Genuine confidentiality has become technically and legally impossible in that realm. Engaging with the public health system turns you into a "transparent patient."
To maximize the security of your data, Dr. Dietmar Luchmann, LLC, operates domiciled in the USA and works entirely outside European health systems. There is no billing with health insurance companies, no reporting to authorities, no connection to ePA, ELGA, or EPD. The following principles describe how your data is handled when using this website and when engaging informationally with Dr. Dietmar Luchmann, LLC.
Psychotherapie.com and Dr. Dietmar Luchmann, LLC, do not collect data from website visitors. No cookies are set, no third-party analytics tools are deployed, no tracking mechanisms are used. You can visit this site without leaving digital traces that are within the control of Dr. Dietmar Luchmann, LLC.
The data privacy of psychotherapy begins even before registration — with the prospective client.
Dr. Dietmar Luchmann, LLC, recommends setting up a separate email address with a provider that allows encryption for all communication related to your psychotherapy. Choose an address that does not contain your real name; avoid addresses like firstname.lastname@provider.com. Instead, choose a neutral designation that allows no inference of your identity. This is a simple measure with significant protective effect. Even the best encryption is of little use if your email address itself makes you identifiable.
Furthermore, Dr. Dietmar Luchmann, LLC, recommends the use of a Virtual Private Network (VPN). While a VPN does not offer absolute anonymity because you can be tracked online today via many characteristics other than just your IP, a VPN significantly increases your data privacy, ensuring that practically no one other than you and your psychotherapist is aware of the psychotherapy.
