Cala collects no data. None. Everything you enter — properties, owners, cadastral values, rental income — is stored only on your device (in the app's local storage) and never transmitted anywhere. Cala has no accounts, no analytics, no advertising, no tracking, and no servers of its own. The app works entirely offline.
We do not collect, transmit, sell or share personal data. The app makes no network requests to us — there is no "us" to send anything to. Deleting the app deletes all data.
In-app purchases (Cala Pro) are processed entirely by Apple through your Apple ID. We receive no personal information about you from a purchase. Apple's privacy policy applies to the transaction: apple.com/legal/privacy.
Deadline reminders are local notifications scheduled on your device. They involve no server and no data transfer.
The app links to official websites (e.g. the Spanish tax agency) and to this support site. These open in your browser; their own privacy policies apply there.
