Terms of service and data protection

What Casas de la Costa is and what it is not

Casas de la Costa is an IT service: an internet platform for publishing and searching property listings and for putting buyer and seller in touch. We are not an estate agency, an agent or an intermediary.

  • We do not sell or buy properties, nor do we act on behalf of the buyer or the seller.
  • We do not visit, value or check the properties, nor do we guarantee that the listings are true.
  • We do not negotiate prices or charge commission on sales. We do not receive or hold money from the transactions.
  • We do not draft or sign contracts. The templates and explanations on the site and from Marina are for guidance: for your transaction, consult a lawyer.

The sale takes place solely between the buyer and the seller, under their own responsibility.

Your account

You must be of legal age, give true details and keep your password safe. You can close your account whenever you like by writing to us: we will delete your data except what the law requires us to keep.

What you publish

You are responsible for what you publish: that the listing is truthful, that you have the right to sell the property or the owner's instruction, and that the photos are yours. We may remove listings and accounts that breach these terms or the law.

Price of the service

Searching and contacting is free. Publishing costs what the prices page says. What you pay for is the use of the platform, never a commission on the sale. Prices

Liability

We use reasonable means to keep the platform working and secure, but we are not liable for agreements, payments or breaches between users, or for damage caused by other users' listings or messages.

Data protection agreement

Who is responsible for what

For the data in your account and your use of the platform, we are the controller, as explained in the privacy policy. Privacy policy

When you receive another person's data through the platform (for example, the name and contact details of a buyer or a seller), you become responsible for what you do with it: use it only for that sale, do not pass it on to third parties or use it for advertising, and delete it when it is no longer needed.

Agencies and developers: data processing agreement

If you are an agency or a developer and you upload personal data of your clients or of other people to the platform, you are the controller of that data and we process it on your behalf, only to provide you with the service, in accordance with Article 28 of the General Data Protection Regulation.

  • We process that data only on your instructions, which are to use the platform as described.
  • We keep the data confidential and apply security measures: encrypted connection, encrypted passwords, daily backups and restricted access.
  • We use as sub-processors the hosting provider and the email provider, with servers in the European Union, and Google and Anthropic for Marina. We will let you know if they change.
  • We help you respond to people's rights and we notify you without delay if there is a security breach affecting that data.
  • When you close the account, we delete that data or return it to you, unless the law requires it to be kept.

You guarantee that you have the right to process that data and that you have informed those people.

Governing law

These terms are governed by Spanish law. Version of 02/10/2026.
