Terms and Conditions

1. Purpose of the contract

ControlarGastos offers a web application to record and analyse personal and shared expenses between individuals, with features for splitting, tagging, debts between members, charts and an assistant based on artificial intelligence.

2. Acceptance and registration

To use the authenticated features you must create an account by providing a valid email and a password. By registering you declare that:

• You are at least 14 years old.
• The data you provide is truthful and up to date.
• You accept these Terms, the Privacy Policy, the Legal Notice and the Cookie Policy.

The email may require verification before the account is enabled. Acceptance is deemed to be given at the moment of registration and is renewed with each sign-in.

3. User account

You are responsible for the confidentiality of your credentials and for the activity carried out from your account. The Service keeps one active session per device using a rotating-token system: if we detect anomalous use of your refresh token, we will automatically revoke the entire session family.

You must immediately report any unauthorised access by writing to [email protected].

4. Plans and subscriptions

The Service is offered in plans with different fees and features. The specific characteristics of each plan are published within the Service and may be updated with reasonable prior notice.

The paid plans are still being defined. In the meantime, new Pro and Premium subscriptions are managed through a waiting list and no amount is charged. When the paid plans go live, specific conditions (price, billing period, cancellation and refund policy) will be published and notified to those on the list.

5. Acceptable use

You undertake not to:

• Share your account with third parties or transfer it.
• Carry out mass scraping, automated data extraction or reverse engineering of the Service.
• Overload the Service with automated requests or circumvent the quota systems.
• Upload personal data of third parties without their consent beyond what is strictly necessary for sharing shared expenses.
• Use the Service for unlawful or fraudulent activities or activities that infringe the rights of third parties.

6. Artificial intelligence features

The assistant and receipt analysis use artificial intelligence models served by external providers (currently OpenRouter, Inc., based in the United States). By using these features you accept that the strictly necessary data (the messages you send to the assistant, the receipt image you choose to upload) is transferred to that provider solely to process your request.

These models can make mistakes: you should not treat the assistant's responses or the automatic receipt extraction as definitive information without reviewing it.

7. User data

The financial data you enter (expenses, income, debts, items, tags, merchants, amounts) is yours. ControlarGastos:

• Does not share it with third parties for commercial purposes.
• Does not use it to train artificial intelligence models.
• Does not publish it or aggregate it for external analysis.

The specific processing is governed by the Privacy Policy.

8. Suspension and cancellation

You can request the cancellation of your account at any time from within the Service itself or by writing to [email protected]. After cancellation we will keep your data for a grace period of 30 days in case you decide to reactivate the account; once that period has elapsed it will be permanently deleted.

Before cancelling, we recommend that you export the information you want to keep using the tools the Service makes available to you.

The provider may suspend or close accounts that breach these Terms, that compromise the security of the Service or that are used for unlawful activities, notifying the user where possible and respecting legally recognised rights.

9. Limitation of liability

The Service is offered "as is" to the extent permitted by law. It does not constitute accounting, tax, legal or financial advisory services. The provider is not liable for:

• Accounting, tax or legal decisions based on the Service's calculations without verification by a professional.
• Indirect losses, loss of profit or loss of opportunity.
• Occasional unavailability of the Service or outages attributable to external providers.

The foregoing applies without prejudice to the mandatory rights recognised to consumers under the applicable legislation.

10. Changes to the service and to the terms

The provider may modify the Service (add, remove or change features) and these Terms to adapt them to the evolution of the product, the applicable regulations or operational decisions. When the changes are substantial they will be communicated with reasonable notice by email or via a prominent notice within the Service.

11. Applicable law and jurisdiction

These Terms are governed by Spanish law. For the resolution of any dispute the parties submit to the courts and tribunals that have jurisdiction under the applicable procedural rules, respecting the mandatory jurisdiction rules applicable to consumers.
