Personal Data
Personal data (personenbezogene Daten) encompasses all information relating to identified or identifiable natural persons -- from names and email addresses to IP addresses, location data, and usage data. Their processing is subject to GDPR requirements and requires clear Consent or another legal basis.
Why is personal data relevant?
Companies must be able to demonstrate at any time on what legal basis data is being processed. Processing is often based on Consent or a contractual necessity. Without a clear legal basis, a legal risk arises.
Technical contexts of processing
Personal data arises not only in forms but also in server logs, APIs, or when integrating Third-party providers systems. Hosting environments and the Server location also play a role in the legal assessment.
Data minimization and purpose limitation
According to the principle of Data minimization , only data required for a specific purpose may be collected. Furthermore, a regulated Data processing agreement is necessary when external service providers are involved in processing.
Common mistakes and misconceptions
Not only names or payment data qualify as personal data. IP addresses, device identifiers, or combined metadata can also allow conclusions about individuals. A purely technical perspective without legal context therefore falls short.
Practical perspective
At BTECH Solutions, we classify every data field by GDPR relevance during the concept phase. Contact forms process only name, email, and message -- IP addresses are automatically deleted from server logs after 7 days. Through Environment variables , we control which data is logged in each environment. All transmission is TLS-encrypted via SSL certificate , and external data flows are contractually secured through Data processing agreement .
