Your data in Evolfit
Last updated: 8 August 2026
This page explains what happens to the data you share with your trainer through Evolfit, including health data. If you got here from the initial questionnaire or from an email of theirs, this is the long version of the notice you read there.
Who is responsible for your data
Your trainer is responsible for your data: they decide what it is used for and they are who you can complain to. Their contact details are in the email they invited you with. Evoltix Solutions is the company that builds and hosts Evolfit, and processes your data solely on their behalf, under a data processing agreement. If you cannot find that email, write to contact@evoltixsolutions.com and we will put you in touch.
What data is collected
Your contact details (name, email, phone and town) and what is needed to plan: sex, date of birth, height, weight and the measurements you record over time, your goals and your training experience. And health data: illnesses or conditions, injuries, regular medication, and allergies or intolerances. If your trainer switches the portal on, also what you log about your workouts and your answers to the review questionnaires. Progress photos only exist if you or your trainer upload them.
What it is used for
So that your trainer can build and follow up your training and nutrition plans, and to talk to you about them. Nothing else: it is not sold or shared with third parties for commercial purposes, and it is not used for advertising or profiling.
On what legal basis
With your explicit consent, which you give by ticking the box in the initial questionnaire or in the link your trainer sends you. You can withdraw it whenever you want by telling them, without affecting what was done before. Withdrawing it means they will no longer be able to use your data to plan: it is not a button in the app, it is a conversation with the person who trains you.
Artificial intelligence and your plan
Draft plans are proposed by an artificial intelligence model, which is sent your profile including your health conditions. No plan reaches you until your trainer has reviewed and approved it: the model proposes, the person decides and signs off. Progress photos are only sent if your trainer explicitly asks for them to be described, and that needs your separate consent.
Who else handles it
Amazon Web Services hosts the database and the photos on its servers in Frankfurt (European Union). Amazon Bedrock generates the draft plans, with the computation inside the European Economic Area. Resend sends the emails: sending happens in the European Union, but it stores the sending metadata (who, when and what subject) in the United States. All of them work under contract and may only use the data to provide that service.
How long it is kept
For as long as you and your trainer keep working together, and afterwards for as long as they consider necessary to account for their work. They decide that period, not Evoltix. If you ask them to delete your data and they agree, it is really deleted: the photos and the portal account too.
What you can ask for
To access your data, correct it, erase it, object to the processing, restrict it, and ask for it in a format you can take with you. You ask your trainer, who is the controller; if they pass it on to us, we help them do it. If you think it has not been handled properly, you can complain to the Spanish Data Protection Agency (aepd.es).
