The GDPR gives you the right to export it and delete it. Before connecting anything, check these three things. To give your data to an AI without losing control you need three things: your data must live in a place that is yours and separate from everyone else's, it must be encrypted, and you must decide what each assistant can read and what it can change. If any of these is missing, you are not sharing data: you are giving it away. Almost all of us have pasted things into a chat without thinking about where they ended up: routines, client notes, half-finished ideas. It works, but it leaves an uncomfortable feeling that is hard to ignore. At Traiker, that discomfort is part of why we exist. ## Where does your data live? It is the first question worth asking of any tool. When you paste information into a chat, it stays inside that application, mixed with your history and subject to its rules. If you switch assistants tomorrow, you don't take it with you. That is why at Traiker we bet on the opposite model: your data in your own database, with the assistant querying it when needed, for example through [MCP](https://traiker.com/en/blog/what-is-mcp-memory-chatgpt-claude-grok). The information is not scattered across conversations; it lives in one place you can review, export or delete. ## Why a database for each person? Because isolation is the easiest defence to understand. If every user has their own database, a mistake on someone else's account does not expose yours, and deleting your account means deleting something concrete, not filtering rows inside a giant table. It is the design decision we are building Traiker on. It costs more to maintain than a shared database, but when we are talking about workouts, health or clients, we prefer to pay that price. ## What encryption should you demand? At the very least, that data travels encrypted and is encrypted when it is stored. This is not a quirk of ours: the [General Data Protection Regulation](https://eur-lex.europa.eu/eli/reg/2016/679/oj) expressly cites pseudonymisation and encryption among the appropriate security measures in its article 32. Also ask who holds the keys. Saying something is “encrypted” means little if anyone inside the company can decrypt it without leaving a trace. ## What can the assistant do with it? Reading and writing are not the same thing. It is reasonable for your assistant to read your gym history to answer you; it is less reasonable for it to modify records without warning. MCP's own [specification on tools](https://modelcontextprotocol.io/specification/2025-06-18/server/tools) recommends always keeping a person in the loop with the ability to reject invocations. In practice, we look for three things: seeing which tools the assistant has within reach, ensuring that tools which write data ask for confirmation, and being able to revoke access in one click. ## What rights do you have? If you live in the European Union, the GDPR gives you the right to access your data, to take it with you in a structured format (portability, article 20) and to ask for it to be deleted (article 17). The [Spanish Data Protection Agency (AEPD)](https://www.aepd.es/derechos-y-deberes/conoce-tus-derechos) explains them quite well. Our advice is to check this before you need it: try exporting your data from a tool on day one. If you can't, you already know how much control you have. It is a two-minute test that says a lot about a service. ## Frequently asked questions ### Is it safe to connect my data to ChatGPT or Claude? It depends on where it is stored, how it is encrypted and what permissions you grant. The connection protocol is only the pipe. ### What happens to my data if I stop using the service? You should be able to export it in a structured format and ask for it to be deleted. The GDPR recognises both rights. ### Can the assistant change my data without asking me? It shouldn't. The MCP specification recommends that a person be able to reject any action, and a good service asks for confirmation before writing.
