Masa is a back-office app for hotels. Each hotel company that signs up gets its own private account, and only that company's users can see its invoices, suppliers, products and stock.
Contact: marios.kouranis@gmail.com
Account details: your name, username, role, the hotel you work at and, if you choose to use it, the email address of your Google account.
When you sign in with Google we receive only your name, email address and Google account ID, to sign you in or to create your company's account. We do not get your password, contacts, files or any other Google data.
Business data you or the system enter: invoices (including those imported from AADE myDATA), suppliers, products, prices, stock counts and orders. If you connect myDATA, we store your myDATA username and subscription key encrypted and use them only to fetch your received invoices.
Only to run the app: to let you sign in, to show you the data for your hotel and to keep a record of who changed what.
We do not sell, share or use your data for advertising.
Data is stored in a PostgreSQL database hosted by Supabase (EU, Frankfurt). The app runs on Vercel and Render. Sign-in uses a secure, http-only session cookie.
You can ask to see, correct or delete your personal data, or to unlink your Google account, by writing to the contact email above. An administrator can also disable your account at any time.
Το Masa είναι εφαρμογή back office για ξενοδοχεία· κάθε εταιρεία βλέπει μόνο τα δικά της δεδομένα. Κρατάμε μόνο τα στοιχεία του λογαριασμού σας (όνομα, ρόλος, ξενοδοχείο και, αν το επιλέξετε, το email Google) και τα επιχειρηματικά δεδομένα (τιμολόγια, προμηθευτές, προϊόντα, απόθεμα) και, αν συνδέσετε το myDATA, τα κλειδιά του κρυπτογραφημένα. Δεν τα πουλάμε ούτε τα μοιραζόμαστε. Για διαγραφή ή διόρθωση στοιχείων γράψτε στο marios.kouranis@gmail.com.
