Privacy Policy
Effective Date: October 10, 2026
Application: Plato POS (iOS / iPadOS) — Developed by Michael Sebastian (msyusw)
1. Overview and Core Philosophy
Plato POS is engineered for food & beverage enterprises with a privacy-first, on-device architecture. Your menu recipes, transactions, table reservations, and financial ledger remain under your strict ownership. Plato POS operates locally on your Apple device and does not sell, broker, or monetize your restaurant's business data.
2. Google Sheets & Google Drive Integration (Limited Use Policy)
Plato POS provides an optional feature allowing restaurant owners to manage menu catalogs and review sales reports directly using Google Sheets.
Google API Limited Use Disclosure:
Plato POS's use and transfer to any other app of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
When you choose to connect your Google Account via official OAuth 2.0 PKCE, Plato POS requests the following specific permissions:
https://www.googleapis.com/auth/spreadsheets: Used solely to read menu item names, categories, modifier groups, and prices from your designated Plato spreadsheet, and to write cashier shift summaries and transaction logs.https://www.googleapis.com/auth/drive.file: Used exclusively to create a single dedicated spreadsheet titled "Plato POS - Katalog Menu & Pembukuan" in your personal Google Drive and open it for your restaurant management. Plato POS never accesses, reads, or modifies any other files in your Google Drive.https://www.googleapis.com/auth/userinfo.email: Used solely to display your connected account email in the app's settings interface.
Strict Storage and Data Handling:
- Google OAuth access and refresh tokens are encrypted and stored exclusively in your local device's hardware-backed Apple Keychain.
- Tokens and spreadsheet contents are never transmitted to any third-party intermediary servers. All communications occur directly between your iPad and Google's official endpoints (
https://sheets.googleapis.com) via encrypted HTTPS/TLS 1.3. - We do not use Google user data to train generalized artificial intelligence or machine learning models.
- You can revoke Plato POS's access to your Google Account at any time from within the app settings or via Google Account Security Settings.
3. Local Storage & Apple Private CloudKit
All core point-of-sale data—including orders, cash shifts, staff clock-in records, table layouts, and modifier groups—is stored locally on your device via SwiftData. If you enable Apple iCloud Sync, data is synchronized through your private CloudKit database container tied to your Apple ID. We have no access to your iCloud container.
4. Local Network & Hardware Connections
Plato POS connects to local kitchen hardware (ESC/POS thermal receipt printers via Wi-Fi or Bluetooth) and synchronizes orders in real-time across Waiter devices and Kitchen Display Systems (KDS) using Apple Bonjour peer-to-peer networking (_exresto-sync._tcp). This network communication remains entirely confined to your restaurant's local Wi-Fi router.
5. In-App Purchases and Billing
Subscription management and software licensing are processed securely by Apple StoreKit. We never collect or store payment card details, bank credentials, or billing addresses.
6. Your Rights and Data Deletion
Under global privacy regulations (including GDPR, CCPA, and Indonesia's UU Perlindungan Data Pribadi / UU PDP):
- You may export your menu and transaction data at any time via CSV or Google Sheets.
- You may permanently wipe all local databases using the "Reset Database" feature in Settings.
- Disconnecting Google Sheets instantly purges the OAuth tokens from your Apple Keychain.
