This policy describes Quall Studio 1.0.0, its apps and the separate OBS plugin. Veneri & Quellis Ltda. is responsible for distribution. Privacy questions and requests: suporte@queven.com.br.
Content you choose to use
The app uses your camera, microphone, screen and scripts for features you activate. Transmission sends this content to the device you connect. In camera teleprompter mode, local recording records the camera without the reading text. Recording does not automatically turn on the microphone.
Screen sharing may include visible notifications and personal information. A receiver can record or broadcast what it receives. Check the source and recipient before starting. Content saved or sent by another app also follows your choices and that app’s policies.
No account is required. The app includes no advertising, advertising tracking, analytics or automatic reporting to the distributor. Quall does not provide a cloud server to receive media or scripts from your sessions.
Connection and pairing
Local discovery shows a generic Quall label with a temporary random identifier, address, port, available capabilities and device role. It does not publish your personal name or persistent identifier. After authenticated pairing, the connected device receives the identity, name and information needed for the session. Initial pairing uses the sender’s six-digit PIN; links compatible with this version can resume without entering it again.
The app stores identity, peers and pairing secrets in private app files or preferences. It adds no separate encryption layer at rest for these files. The information is not anonymous. Protect your device and share the PIN only with intended participants.
Media uses DTLS-SRTP; scripts and commands use data channels protected by DTLS. After pairing, signaling containing identity, connection descriptions and metrics is also encrypted and authenticated by the application. Local discovery, addresses, ports, service presence and traffic volume remain visible on the network. Use a trusted network. Manual addresses and network configuration determine the connection’s reach. All participants need a compatible version; links from previous versions require a new PIN pairing.
Files and retention
Scripts, preferences, identity and pairing information persist between app launches. There is no general automatic expiry. Forget paired devices removes peers saved on that device. It does not delete scripts, identity, logs, recordings or copies on other devices, and does not guarantee that an active session ends.
Manage recordings in Gallery, Photos or their destination folder. Clearing app data or uninstalling can remove private app files according to the operating system. Exported videos, photo libraries and copies in other apps must be managed separately.
Android declares allowBackup=false for app data. Photo libraries, exports, system copies and services such as iCloud depend on device settings. Ending a session does not delete every copy.
Diagnostic records
The app keeps local technical logs and counters to explain errors and operation, including in distribution builds. Filters reduce exposure of PINs, keys, identifiers, addresses and content in the handled logging paths. They cannot guarantee removal of every piece of information entered as free text.
Records remain in operating system logging facilities or local files. On Android, reception session counter files rotate by count: creating new reports can automatically delete older ones. This does not set an expiry in days for all records. On Windows, app log files have no automatic expiry. A separate virtual camera integration, when used, keeps its own records. The Microsoft Store edition does not include or install the virtual camera component. This optional output works when the separate component is already installed on Windows; installing it may require administrator permission. Quall Studio's core features work without this component. System log retention depends on the operating system. Logs are not automatically sent to support.
Before voluntarily sending a screenshot or file to support, review it and hide personal information, addresses, PINs and secrets. Avoid sending personal media or internal files unnecessarily.
Permissions and choices
You can review and revoke permissions in system settings. Denying a permission can make the corresponding feature unavailable. Permissions vary by platform.
- Camera and microphone: for video and audio you activate.
- Screen capture: to share content authorized through the operating system.
- Local network: to discover and communicate with selected devices.
- Photos, Gallery or files: to save and access content for the selected feature.
- Android notifications and foreground services: to indicate and maintain active operations.
- Android USB: for compatible accessories you connect and authorize.
Separate OBS plugin
The plugin receives content sent through Quall. OBS records or broadcasts the scene according to your configuration. The plugin stores identity and pairing information; properties and scene collections may store the address and PIN. Hiding a PIN in the interface does not encrypt the scene file.
Review and remove private information before sharing OBS settings, scenes, screenshots or logs. The plugin is separate from the iPhone and iPad app.
Website, support and requests
Quall support pages have no collection form or first-party analytics. When you open our website, policy or support pages in a browser, Locaweb hosting may record technical request data, such as IP address, date, time and the requested page, to deliver pages, maintain security and diagnose faults. Retention follows the needs of these purposes and applicable legal obligations, under the provider’s policy.
Sending email provides your address, message and any attachments for support. This is separate from app sessions. We do not sell session data or use it for advertising.
For questions about data use or requests to access, correct or delete information you provided to support, contact suporte@queven.com.br. Files on your devices and recipients’ copies are managed by their users. The distributor cannot access or remotely delete them.
