1. Scope, controller and contact
Zentron Technology Co.,Ltd. (Zentron, we or us) is responsible for the processing described in this policy. It covers zentronoutdoor.com, website support and dealer enquiries, and the ZEN LINK mobile app. App functions depend on the version, compatible device and operating system.
Our published address is Room 301, 12th Floor, Waiyun Building, No. 46 Futian South Road, Futian Street, Shenzhen, Guangdong 518000, China. For privacy questions, complaints or requests concerning your information, contact:
2. Website enquiries, registration and repairs
When you contact us or submit a service form, we process the details you provide: name, email, telephone number, device model and serial number, purchase date and seller, shipping or return address, problem description, and relevant photos or purchase documents. Repair references and status records support follow-up and after-sales service.
Dealer applications include contact details, country, business website, company size, sales regions, expected quantities and the experience or product information you choose to provide. We use them to assess and respond to the application.
Email verification processes your email address and verification code to confirm access to that address. Required fields are identified on the form; omitting them can prevent the requested service. Provide only relevant information and redact unrelated personal details from attachments. A service request does not itself authorise promotional messages.
3. Website access, cookies and browser storage
When you visit the website or use online services, hosting and delivery providers may process your IP address, browser and operating-system information, requested URLs, access times and response or security logs to deliver pages, handle requests and protect services. The static website is delivered through Cloudflare; service forms communicate with Zentron’s service platform.
The language recommendation stores the last reminder time in browser local storage under zentron-language-reminded-at and in the cookie zentron_language_reminded_at. The cookie lasts seven days; the local timestamp remains until cleared and is used to calculate a seven-day reminder interval. The repair form uses session storage under zentron:rma:number to remember your repair reference within the browser session.
You can clear or block cookies and browser storage in your browser settings. This may repeat language prompts or require you to re-enter a repair reference. The website uses Google Analytics 4 to measure page visits and website use. Google may process page URLs, referrers, browser and device information and interaction events, and use cookies to distinguish visits. Processing requiring consent needs appropriate information and a choice; this policy is not a substitute for that consent.
Loading a dealer map sends map and network requests to Google Maps. Using the nearby-dealer function requests your browser’s location permission. Starting an embedded video connects to YouTube. These providers may process device, IP, location or interaction information and use their own storage under their policies. External links, app stores and sharing destinations have their own terms.
4. App location, orientation and weather
After location permission is granted, ZEN LINK can process latitude, longitude, altitude, accuracy and timestamps, including precise location where permitted, to show your position and create or view markers. Compass and motion readings support orientation. Saved markers and the last known position are stored on your phone.
The current App uses foreground location. Live map updates stop when the App is in the background or the map is inactive. The current permission workflow does not request or start background location tracking.
When the App is in the foreground, online and already authorised for location, it may retrieve weather automatically by sending latitude, longitude and the selected language to WeatherAPI.com. iOS or Android may also require location permission to read a Wi-Fi network name or discover a device; this is separate from team location sharing.
5. Phone, network and connected-device information
For discovery, pairing and connections, the App can read your phone brand or model, a phone identifier used for pairing, Bluetooth device identifiers and the current Wi-Fi network name. First Bluetooth pairing sends the phone identifier and brand or model to the compatible thermal device.
The App reads and stores the connected device’s model, serial number, firmware or core version and settings for recognition, controls, media access, updates and troubleshooting.
Connection and firmware-update records are queued locally and can be sent automatically to Zentron when internet access is available. They include product type, serial number, firmware versions, mobile platform, App and operating-system version information, and phone time. Update records can include download times, update status and error or result descriptions.
6. Optional team location sharing
Where available, creating or joining a team sends an installation identifier, request identifier, nickname, chosen colour, device model and, when selected, serial number to the Zentron team service. Team names or invitation codes are included for the chosen action.
While you belong to a team and keep the map active in the foreground, latitude, longitude and heading are sent to the team service. Members receive shared profiles, device details, positions, headings and update times. This does not automatically publish your saved marker history.
Leaving the map, losing connectivity or moving the App to the background pauses the live connection but does not leave the team. Returning can resume sharing. Use leave-team or, where applicable, disband-team to end participation. Share another person’s information only with appropriate authority.
7. App media, feedback and diagnostics
The App processes device photos and videos when you browse, download or save them. Photo-library access supports saving and maintaining the App album. Exported copies remain in the system photo library until deleted separately.
Submitting App feedback sends your description, email, product type, serial number, mobile platform and App version information, and phone time. An available local device diagnostic archive can be attached. Pending feedback may be stored locally and sent when connectivity returns; automatic connection and update logs are separate from this voluntary feedback.
8. Purposes and legal grounds
We use the described information to answer enquiries, assess dealer applications, verify email access, administer device registration and repairs, provide App device, map, weather and team functions, deliver firmware updates, troubleshoot and protect service security and reliability.
Where a legal basis is required, processing rests on providing a requested service or taking requested pre-contractual steps, consent where required for optional processing, legitimate interests in responding to enquiries and maintaining secure, reliable services subject to your rights, or legal obligations. Accepting terms or continuing to browse does not replace required consent or system permissions.
9. Recipients and third-party services
Zentron receives the submitted service, connection, update, feedback and team information. Team members receive information shared within their team. Hosting, technical support, email delivery and repair or shipping providers may process information needed for their respective tasks; information should be limited to those tasks.
Google Analytics 4 processes website usage information; Google Maps processes map requests and associated network or device information; WeatherAPI.com receives weather-query coordinates and language. Google’s policy also covers YouTube. Review the providers’ policies:
https://policies.google.com/privacy
https://www.weatherapi.com/privacy.aspx
https://www.cloudflare.com/privacypolicy/
Information may also be disclosed to comply with lawful requests, protect rights or establish, exercise or defend legal claims. Further uses or disclosures that require consent are subject to the required notice and consent.
10. Storage, retention and security
App preferences, device records, markers, media caches and pending logs or feedback are stored on your phone. Team credentials and recoverable sessions use operating-system secure storage. The App uses live team positions for the active session rather than saving a team-position history.
Service records are kept for the time needed to complete the request, maintain repair or warranty records, investigate technical or security issues, comply with legal obligations or resolve claims. Retention depends on the record and purpose; ask us about the records relevant to you. Deleting local App data does not delete records already received by a service or media exported elsewhere.
Available platform protections and access controls reduce the risk of loss or unauthorised access. No transmission or storage system guarantees absolute security. Avoid sending passwords, payment-card details or unrelated sensitive information in support requests.
11. International processing
Zentron is based in China. Processing locations also depend on the service and provider involved, so information may be processed outside your country. Applicable international-transfer requirements must be met, including appropriate safeguards where required. Contact us for the locations and transfer arrangements relevant to your information; this policy does not claim that all data stays on your phone or in one country.
12. Permissions, choices and your rights
Review App permission status and change location, Bluetooth, nearby-device, local-network or photo-library access in system settings where supported. Refusal or withdrawal may prevent the associated function. It stops affected future access, but does not automatically delete service records, end team membership or remove exported media.
You may request access, correction or deletion of information we hold. Depending on applicable law, you may also restrict or object to processing, receive portable data, withdraw consent, appoint an authorised representative or complain to a competent data-protection authority. Withdrawal does not affect previously lawful processing. We may need proportionate information to verify your request and must observe legal retention duties. We respond within applicable statutory periods and do not penalise you for exercising these rights.
13. Children and guardians
The services are intended for people able to use the products and services lawfully. Minors should involve a parent or guardian and comply with applicable age requirements. If you believe a child has provided personal information without the required authority, contact us so that we can review the information and take appropriate action, including deletion where required.
14. Policy changes
We update this page and its date when privacy practices change. Material changes will be communicated through appropriate notices; new permissions or consent will be requested where required before the corresponding processing. Contact the address in section 1 with questions about this policy or an earlier version.
