01Scope & contact
This notice covers browsing lynzrc.com, product availability and purchase enquiries, and the LynzRC Free and LynzRC Pro iOS apps. Free 2.4.1 is available on the App Store with visual tracking and compatible legacy Bluetooth two-axis servo gimbal control. Pro 2.4 is awaiting Apple review. The sections below describe each edition's data handling. Website enquiries are free and help confirm compatibility, app availability and purchase arrangements. They collect no payment or deposit. The contact is LynzRC / XK, using the email below.
02App filming & on-device processing
Camera images, detection and visual tracking are processed on your phone. Videos you choose to record are saved on the device; automatic diagnostics upload no videos, photos or original camera frames. The apps do not read or upload contacts. Free sends no diagnostics to our server. The available 2.4.1 release provides visual tracking and compatible legacy Bluetooth two-axis servo gimbal control. Pro provides compatible DockKit gimbal control. Sharing diagnostics is not a condition of using purchased features.
03Encrypted models & Apple’s key service
Both editions use Apple Core ML model encryption. The first load of an encrypted model requires an internet connection: Apple’s system retrieves and securely stores the decryption key automatically. Loading the same model afterward normally needs no further key download. Inference still takes place on your phone; key retrieval does not send camera images to LynzRC. Apple’s system service handles the key request. If it fails, the app asks you to reconnect and retry.
04Optional Pro performance diagnostics
Server diagnostic uploads in Pro are off by default. Only after you explicitly opt in within the app does LynzRC receive an allowlisted, de-identified projection of performance and fault diagnostics over HTTPS, such as app version, frame rate, processing time, memory use, thermal state and gimbal call results. Upload packages contain no video, original frames, contacts, email, account or device identifiers, or model weights. Each upload has a separate reference number for receipt verification and deletion requests. You can turn sharing off at any time in settings; this stops new uploads and clears the local pending queue. Receiving a network request involves necessary connection information, and operational logs may record access or faults.
05Diagnostic retention & deletion
Pending diagnostic uploads expire after 24 hours, with a total pending-content limit of 8 MiB. The app clears expired queue records while running and never uploads expired data; records left while the app is closed are handled the next time it runs. This limit applies to the automatic upload queue; videos and diagnostic exports you save locally remain under your control. Server diagnostics are removed by a scheduled task once they are 7 days old, with a cleanup interval of no more than 15 minutes. To request earlier deletion of received diagnostics, email support below with the upload reference shown in the app. Withdrawing upload consent does not automatically delete data already received. Website enquiries follow the separate retention arrangements below.
06Information you provide
The form collects your email, country or region, app or app + gimbal interest, iPhone model, iOS version, gimbal quantity of interest and any RC vehicle or message you choose to add. We record your contact consent and whether you separately opt in to app launch and kit availability updates. Link campaign tags may be saved with the registration to understand where it came from.
07How we use it
LynzRC uses this information to check phone and equipment compatibility, confirm purchase and delivery arrangements and follow up on your interest registration by email. Please only include information relevant to your registration.
08Processing & storage
LynzRC receives and stores your submission on its own server and notifies the team through its configured email service. If notification is not yet sent, your registration remains saved while the team notification is pending. Subsequent correspondence is handled by our email service.
09Browser storage & website operation
The site remembers language and manually chosen price-reference region preferences in your browser and keeps a registration receipt during the current browsing session. Automatic region suggestions use language-region and timezone settings locally in the browser, without requesting precise location or a third-party IP lookup. Choosing Auto reference clears the manual region preference. The site includes no advertising or third-party analytics scripts. The registration service temporarily uses the access IP for submission rate limits; operational server logs may contain access and error information.
10External links & stored records
Bilibili, YouTube, hardware brand websites and package release sources are external services with their own data-handling rules. Submitted details are retained for enquiry follow-up, and the site does not currently delete registrations automatically. Contact XK to request deletion when follow-up is no longer needed. Administrator backups and email records may also contain the submitted details.
11Launch and availability updates are your choice
We send app launch and kit availability updates only if you separately opt in. Leaving this option unchecked does not affect your registration or compatibility check. You can unsubscribe by email at any time.
12Do not submit payment or sensitive details
This form does not take payment and does not ask for payment passwords, card numbers, a full shipping address or identity documents. Please do not include these in your message.
13Corrections, deletion & unsubscribing
To change or delete submitted information, or unsubscribe from app launch and kit availability updates, contact us from the email address used in your registration and describe your request so we can verify and process it.
