Using ChatGPT privately: why your personal data doesn't belong there either

Even for personal use, you shouldn't put personal data into ChatGPT and similar tools. Everything you paste is processed on someone else's servers. The safe way: remove personal details locally, before the text leaves your device.

Updated

The same rule applies in private life: personal data does not belong, unprotected, in ChatGPT or any other AI tool. Everything you paste leaves your device and is processed on the provider’s servers, often outside the EU. The safe way is to remove personal details locally before you hand the text to the AI.

Why this matters for personal use too

It is not only about companies. As a private individual, you quickly paste very personal things into an AI tool: your own CV, a medical letter, a rental contract, a letter from an authority, bank statements, or a message about your family. The moment you do, you have given up control over that data. You cannot be sure how long it is stored or what else it is used for.

What an AI provider can do with the text

Content you enter can be stored, analyzed, and, depending on the provider and your settings, used for training. For harmless questions that is fine. For names, addresses, health details, or financial data it is different, because those details can be linked to you and to other people.

The simple solution: anonymize locally

You do not have to give up AI. Remove personal details before the text leaves your device:

  1. Open the document or text locally in a tool that runs on your device, for example Stript.
  2. Review the personal data. Names, addresses, phone numbers, IBANs, and more are highlighted. You confirm them.
  3. Anonymize and use the AI. Copy the version with placeholders into ChatGPT or Claude and ask your question.
  4. Restore the answer. Put the real details back locally afterward.

Typical personal uses

  • Improve a job application and CV without revealing your address and contact details.
  • Have a medical letter or finding explained in plain language without transmitting health data.
  • Summarize contracts and letters from authorities.
  • Draft personal emails without exposing other people’s names.

Frequently asked questions

Isn’t this overkill for private use? It is about habit. Getting used to removing personal data before using AI protects you and others, without giving up the benefit of AI.

Do I still get the full benefit of the AI? Yes. The AI answers your question just the same, only with placeholders instead of real names. You keep the mapping locally.
