Helio Family Finance · last updated 13 October 2026
Helio Family Finance is a budgeting service run by Oleksandr Slobodianiuk, an individual based in Porto, Portugal. There is no company behind it yet. He is the controller of your personal data under the GDPR. Contact: hello@heliofamily.com.
From version 2.0, the Helio iPhone app uses the same service. In this version, you sign in with Apple or Google. Voice entry, receipt scan, PDF statement import, the Assistant chat and the “Talk to Helio” voice call use OpenAI, through our server and without your user id, and only after you tap Allow on a consent screen; you can turn the consent off in Settings. CSV import never leaves your device. Our server keeps no AI request content. OpenAI may keep API requests for a limited period under its own terms and does not use API data for training. The full policy for version 2.0 is at /app-privacy.html.
A free plan is open to anyone with a Google account on the web. From version 2.0, it is also available with an Apple or Google account in the iPhone app. You load your own bank statements, the service sorts the operations into categories, and shows you where the money went. From version 2.0, Premium is an auto-renewing App Store subscription in the iPhone app; see the Terms of Service.
A statement file is read in your browser. The file itself is not uploaded. Only the operations read from it are written to your household, after you confirm them.
We process this data to give you the service you signed up for: to show your operations, categorise them and keep your rules. The legal basis is performance of a contract (GDPR Article 6(1)(b)). For the waiting list it is your consent (Article 6(1)(a)), which you can withdraw at any time.
In Google Cloud Firestore, region europe-west1 (Belgium), inside the European Union.
Google Cloud (Firebase) is our processor: it provides sign-in, the database and the servers that run
the service. From version 2.0, in the iPhone app, OpenAI is also our processor for the AI features described above. We do
not sell your data or share it for advertising. Your household's data is visible to the members
of that household, and to us only when you ask for help with it.
The website and the cabinet keep your language and theme choice, and the cabinet keeps a temporary copy of your operations for speed, in your browser's own storage. Firebase Authentication keeps your sign-in there too. There are no advertising or tracking cookies.
Until you delete it. Waiting-list addresses are kept until the paid plans open or until you ask us to remove yours.
In the cabinet, open your profile and choose “Delete my account and data”. It cannot be undone.
Backups of our database are taken daily and each is kept for 30 days, so deleted data can remain in backups for up to 30 days before it expires.
You can also ask us to delete your data by email.
Under the GDPR you have the right to access your data, to have it corrected, to have it erased, to receive a copy in a portable format, to object to processing and to restrict it. Write to hello@heliofamily.com and we will answer within one month. You also have the right to complain to the supervisory authority. In Portugal that is the CNPD (Comissão Nacional de Proteção de Dados, cnpd.pt).
