This Privacy Policy explains how Salon24h collects, uses, stores, and shares information when you use the Salon24h website and mobile app. Last updated: August 24, 2026.
We collect the following types of information: (a) Account information: full name, phone number, email, and password (encrypted) when you register or log in; (b) Business information: salon/store name, address, phone number, logo, and bank account details (for generating payment QR codes) provided by the salon owner; (c) Your customer data: names, phone numbers, service history, and notes entered by the salon owner/staff to manage their own customers; (d) Operational data: appointments, orders, payment transactions, inventory, and staff commissions; (e) Device information: push notification tokens (Firebase Cloud Messaging) used to send new-appointment notifications; (f) Usage logs: login activity and access times, used to keep the system secure.
We use the information we collect to: provide and operate Salon24h's features (appointment booking, customer/staff management, POS sales, inventory, reporting); send instant push notifications when a new appointment is assigned to a staff member; generate bank-transfer QR codes for payment transactions; issue receipts; provide technical support when you contact us; and improve service quality and fix issues.
We do not sell your personal information to third parties. Information is only shared: (a) with technical service providers necessary to operate the system, such as Firebase (Google) for push notifications and server hosting providers for data storage; (b) when generating a payment QR code, the salon's bank account name and number are sent to the bank/NAPAS partner's QR image service to render the scannable code; (c) when required by law or to protect the legitimate rights of Salon24h and its users.
Data is transmitted over encrypted connections (HTTPS). Account passwords are one-way encrypted and never stored as plain text. Data access is role-based (owner, manager, staff) — each account only sees data relevant to its role and branch. Data is retained for as long as the account remains active and as required by applicable law.
The Salon24h mobile app may request the following permissions, used strictly for the purposes described and never collected covertly: Bluetooth — to connect to a thermal receipt printer via Bluetooth; Local Network — to connect to a thermal receipt printer over LAN; Push Notifications — to receive new-appointment alerts; Internet — to sync data with the server. Receipt data printed via Bluetooth/LAN is sent directly from your device to the printer and does not pass through Salon24h's servers.
You may request access to, correction of, or deletion of your personal information by contacting us using the details in Section 9. Salon owners can manage, edit, or delete their own customer/staff data directly within the system.
Salon24h is not directed at users under the age of 13, and we do not knowingly collect personal information from children.
We may update this Privacy Policy from time to time. The most recent update date is shown at the top of this page. Continued use of the system after changes take effect constitutes acceptance of the updated policy.
