5. Data Quezlo collects
Quezlo collects no personal data through Cricket Ground Studio. Quezlo runs no server for Cricket Ground Studio. We do not receive your matches, profiles, stream keys, videos or purchases. Only the services listed below receive data, and only in the cases described.
6. Data that leaves your device when you choose
These transfers happen only when you, or your staff, start them.
| What | Sent to | When | Editions |
|---|---|---|---|
| Live video and sound | YouTube (Google) (privacy policy) | Only when you press Go live with a YouTube stream key. What happens to the video on YouTube follows its own rules. | Android phone app, Windows laptop studio |
| Live video and sound | Facebook (Meta) (privacy policy) | Only when you press Go live with a Facebook stream key. What happens to the video on Facebook follows its own rules. | Android phone app, Windows laptop studio |
| Live video and sound | Any RTMP server you type (yours or a service you choose) | Only when you press Go live with that address. That server's owner decides what happens to the video. | Android phone app, Windows laptop studio |
| Player card link: name, role, city, country, shirt number, Player ID, batting and bowling style (never CNIC, phone or date of birth) | Anyone you send the link to. The card page is hosted by Netlify at groundstudio-players.netlify.app. (privacy policy) | Only when you share your player card as a link or QR code. The card details are inside the link, so anyone who has the link can read them. When someone opens the link, Netlify sees their IP address; the card details after the # are not sent to Netlify's server. | Android phone app |
| Posters, videos, scorecards and match files | The app you choose in the share sheet (for example WhatsApp) | Only when you tap Share. | Android phone app |
| Recordings, highlights, posters and the copied scorecard text | Whoever you send them to yourself | The Windows app has no share sheet. It saves files in folders you choose and can copy the scorecard text to the clipboard. You send them yourself, for example with WhatsApp. | Windows laptop studio |
| Crash report: app version, time, phone make and model, Android version and technical error details | The app and person you choose in the share sheet (for example email to us) | Only when you tap Send report after a crash. | Android phone app |
| Match package, result and backup files | A ground's tournament website | Only when you download or upload these files yourself. The Windows app has no direct connection to any website. | Windows laptop studio |
| Live video (bonding) | Your own relay server | Only if you set up the optional relay. The server is yours, not Quezlo's. | Windows laptop studio |
| Video, scores and control commands | Your own camera phones, IP cameras, laptop and crowd scoreboard on the same local network | While you use these features. This traffic stays on your local network. | Android phone app, Windows laptop studio |
7. Third-party services and SDKs
These companies receive data in the cases below. Each one handles it under its own privacy policy (linked).
| Service | What it does | Data it receives | Editions |
|---|---|---|---|
| YouTube (Google) | Live stream destination you choose | The video and sound you stream, sent with your stream key | Android phone app, Windows laptop studio |
| Facebook (Meta) | Live stream destination you choose | The video and sound you stream, sent with your stream key | Android phone app, Windows laptop studio |
| Netlify | Hosts the player card page | The IP address and browser details of people who open a player card link | Android phone app |
| GitHub (Microsoft) | Update check | Your IP address, the app version, the repository name and any access token you entered, only when you press Check for update under Settings → Updates. The update file and its signature are downloaded from GitHub. | Windows laptop studio |
| Apple App Store | App download and in-app purchases | Apple handles payment and your Apple ID. Quezlo never sees your card details. | iPhone, iPad and Mac app |
| Google AdMob and Google User Messaging Platform | Banner ads and the ad consent form (iPhone and iPad only) | IP address (used to estimate a general location), device and app information, device identifiers other than the advertising ID, ad views and taps, and diagnostics | iPhone, iPad and Mac app |
8. Advertising
The iPhone and iPad app shows banner ads from Google AdMob to free users. There are no ads on the Mac, for Pro users, in the Android phone app or in the Windows app.
- Before any ad loads, Google's consent form (User Messaging Platform) is shown where the law requires it.
- Ads are non-personalised and treated as child-directed, with content rated G at most, unless the user is a known adult who has consented. This version does not ask your age, so all ads are served this way today.
- The app does not ask for tracking permission (App Tracking Transparency), so Google's SDK cannot read your advertising identifier (IDFA).
- Google's SDK may still collect the IP address, device and app information, ad views and taps, and diagnostics to show ads, measure them and prevent fraud. Google is responsible for this data under its own policy.
- You can change your choice at any time in the app menu: Ad privacy choices.
9. Device permissions
The app asks for a permission only when you use the feature that needs it. You can refuse or withdraw any permission in your device settings; only that feature stops working.
Android phone app (Package name: pk.groundstudio.app)
| Permission | Platforms | Why |
|---|---|---|
| Camera | Android | Films the match for live streaming and recording, scans QR codes, and lets the phone work as an extra camera. Used only while one of these screens is open or you are live or recording. |
| Microphone | Android | Adds ground sound and commentary to the live stream and recordings, sends sound from a camera phone to the control phone, and records voice-overs in the video editor. Used only while one of these is in use. |
| Internet and network state | Android | Sends the live stream and connects to your camera phones, IP cameras and laptop. |
| Wi-Fi state, change Wi-Fi state and Wi-Fi multicast | Android | Finds your camera phones, IP cameras (ONVIF), DroidCam and the laptop on your local network, and creates a Wi-Fi Direct camera network. |
| Nearby Wi-Fi devices | Android 13 and newer | Needed only to create or join a Wi-Fi Direct network for camera phones. Declared as never used for location. |
| Location (precise) | Android 12 and older only | Older Android versions require it to use Wi-Fi Direct. The app never reads, stores or sends your location. |
| Notifications | Android 13 and newer | Shows the "Live video and recording" notification while you are live or recording. |
| Foreground service (camera, microphone, connected device) | Android | Keeps the live stream or recording running when the screen is off or you switch apps. A notification is always shown while it runs. |
| Keep awake (wake lock) | Android | Stops the phone from sleeping while you are live or recording. |
| Storage (write) | Android 9 and older only | Saves posters, designs and videos to the gallery. Newer Android versions need no permission for this. |
Photos, videos and music are picked with the system picker, so the app does not ask to read your gallery. The email picker uses the system account chooser and does not ask for access to your accounts.
Windows laptop studio
| Permission | Platforms | Why |
|---|---|---|
| Camera and microphone | Windows | Uses the USB or HDMI cameras and microphones you pick for the live stream, recordings, the stump mic and the walkie-talkie. Windows privacy settings control this access. |
| Local network and Windows Firewall | Windows | Lets phones on your Wi-Fi connect as cameras and open the scoring, umpire, commentator and crowd pages. Phones find the laptop by mDNS. The optional "Full power" setting adds a firewall rule for this program on Private networks only, and you can undo it. |
| Internet | Windows | Sends the live stream, checks for updates when you press Check for update, and connects to your own relay server if you set one up. |
iPhone, iPad and Mac app (Bundle ID: pk.groundstudio.cricketGroundStudio)
| Permission | Platforms | Why |
|---|---|---|
| Network (internet) | iOS, iPadOS, macOS | Talks to the App Store for purchases and, on iPhone and iPad, loads ads. |
| Tracking (App Tracking Transparency) | iOS, iPadOS | Not requested. The app does not track you across other companies' apps and websites. |
This version does not use the camera, microphone, photo library, location, contacts or local network.
10. What we do not do
- No analytics or tracking SDK in any edition.
- No crash-reporting SDK. A crash note stays on your device until you choose to send it.
- No location tracking. The location permission on Android 12 and older is used only for Wi-Fi Direct.
- We do not sell your data.
- No Quezlo account and no cloud sync. If we add them, we will update this policy first.
- The Android phone app removes the ONNX Runtime telemetry component, so the background remover sends nothing to Microsoft.
- No YouTube or Facebook sign-in or API access. The app only uses the stream key you paste.
- No ads in the Android phone app or the Windows app.
11. Security
- Live streams to YouTube and Facebook use RTMPS (encrypted) with certificate checks. A custom server you type may use plain rtmp://, which is not encrypted.
- Local network links (camera phones, IP cameras, the laptop's phone pages and the crowd scoreboard) use plain HTTP and are not encrypted. Use them on a Wi-Fi network you trust.
- The crowd scoreboard uses a long secret link. The laptop's browser pages need a phone code and lock for 10 minutes after 5 wrong tries. The walkie-talkie uses an encrypted (https) link with a certificate made on each laptop.
- Keep your stream keys secret. Anyone with your key can stream to your channel.
- Windows updates are installed only if they carry our digital signature. Licence keys are checked offline with a digital signature.
- On Android, app data is in the app's private storage and is excluded from cloud backup.
12. How long data is kept
- Your data stays on your device until you delete it, or delete or uninstall the app. Quezlo keeps no copy.
- Videos you streamed stay on your YouTube or Facebook channel until you delete them there.
- Emails you send us are kept as long as we need them to help you. Ask us and we will delete them.
13. Deleting your data
The same steps are also on https://quezlotech.com/delete-account.
Android phone app
- Organizer: open Settings and tap Delete all my data. Player: open your Profile and tap Delete all my data.
- The app asks you twice, then clears everything and closes.
- If that does not work, open Android Settings → Apps → Cricket Ground Studio → Storage → Clear storage. Uninstalling the app also removes its data.
Removed: Matches, teams, players, your profile, tournaments, designs, sponsors, settings, stream keys and the crash note.
Not removed: Photos and videos you saved to the gallery, videos on your YouTube or Facebook channel, and player card links you already sent (the details are inside the link). Delete those in the gallery or on that platform.
Windows laptop studio
- Close Cricket Ground Studio.
- Press Windows key + R, type %APPDATA%\Ground Studio Desktop and press Enter. Delete that folder.
- To remove the program, open Windows Settings → Apps and uninstall Cricket Ground Studio.
Removed: Matches, teams, players, imported tournament data, settings, stream keys, the licence key and logs.
Not removed: Recordings, posters and backups you saved in other folders, and a small record of the trial start date (no personal data). Delete your files yourself.
iPhone, iPad and Mac app
- Delete the app from your device. This removes your scores, settings and the ad consent choice.
- Deleting the app does not cancel a subscription. Cancel it in your Apple ID settings (Settings → your name → Subscriptions).
- Purchases are recorded by Apple, not by Quezlo. To reset ad choices first, use Ad privacy choices in the app menu.
Removed: Everything the app stored on the device.
Not removed: Your purchase history with Apple, and data Google holds under its own policy for ads you saw.
Data held by Quezlo. Quezlo holds no account or app data for Cricket Ground Studio. If you emailed us, you can ask us to delete those emails.
14. Your rights
You can ask us what personal data we hold about you, and ask us to correct or delete it, or stop using it. Email [email protected]. We answer within 30 days. If you are not happy with our answer, you can complain to the data protection authority where you live.
15. Children
Cricket Ground Studio is made for clubs, grounds and academies. It is not directed at children.
- A player under 13 can only have a profile if a parent or guardian ticks the box confirming they are filling it in.
- The CNIC field appears only for players aged 18 or older. It is optional, never shown to others and never sent anywhere. It stays on the phone.
- We do not knowingly collect personal data from children. Quezlo receives no player data at all.
- In the iPhone and iPad app, ads are non-personalised and treated as child-directed (content rated G at most) unless the user is a known adult who has consented through Google's consent form. Choices can be changed in the menu under Ad privacy choices.
16. Changes to this policy
We update this page when the app changes, and change the effective date at the top. If a change affects what data is collected or shared (for example, adding accounts, cloud sync or new ads), we update this policy before the change goes live.
