Privacy Policy
This policy explains what information the amplian app ("the app") collects, how it is used, and the choices you have. The app is provided by NOVA BRIDGE TRADING LIMITED, UNIT 411A3, 4/F. POLY CENTRE,15 YIP FUNG ST., FANLING HK ("we", "us").
Information we collect
Account information. When you create an account we collect your email address and a password. We store your password only in a securely hashed form; we cannot read it. You may also set a nickname and your preferred temperature and measurement units.
Device schedules. The schedules ("recipes") you create for your devices are stored on our servers so that they are available on any phone you sign in on.
Security information. When you register we record the IP address and a random identifier of the app installation. We use them only to prevent abuse, such as automated sign-ups.
Device and environment data. Device control is provided through the platform of our service provider, Tuya. When you use the app, the following is processed by Tuya on our behalf: your gardens and their names, your devices and their settings, sensor readings (temperature, humidity, VPD), and a history of device activity. Your Tuya account is created automatically from an internal identifier; your email address is not shared with Tuya. This data is stored in Tuya's United States data center.
Wi-Fi details. When you add a device, the Wi-Fi network name and password you enter are used to connect the device to your network.
Information stored only on your phone. Your sign-in session, the garden you last selected, and your dashboard layout are stored only on your phone.
Permissions
- Bluetooth is used to find and set up new devices.
- Location (Android only) is required by Android for Bluetooth scanning. It is requested only while you add a device; the app does not use or store your location.
What we do not do
The app does not show ads, does not use third-party analytics or advertising SDKs, does not track you across other apps or websites, and does not sell your personal information.
How we use information
We use the information above only to provide the app: to sign you in, to let you set up and control your devices, to show your environment data, to keep your schedules, and to protect the service from abuse.
Service providers
We share information only with service providers that help us run the app:
- Tuya — device connection, control and data, as described above.
- Railway and Neon — hosting of our servers and account database.
- Cloudflare — network security and delivery for our servers.
Data retention
We keep your account information and schedules for as long as your account exists. When you delete your account, they are deleted as described in Delete your account.
Security
All communication between the app and our servers is encrypted (HTTPS). Passwords are stored only as secure hashes.
Children
The app is not directed to children under 13, and we do not knowingly collect information from them.
Your rights
You can view and change your account information in the app, and you can delete your account at any time (see below). Depending on where you live, you may have additional rights, such as to request a copy of your data. To make a request, contact [email protected].
