Privacy Policy for RuleNet: Block WiFi & Internet
Effective date: October 31, 2026 Application: RuleNet: Block WiFi & Internet (RuleNet) Package name: com.krepelstudio.rulenet Developer: Krepel Studio Website: https://krepelstudio.com/ Contact: Krepelstudio@gmail.com
Krepel Studio ("we", "us", or "our") provides RuleNet: Block WiFi & Internet ("RuleNet" or the "App"), an Android application for controlling individual applications' access to Wi-Fi and mobile data.
This Privacy Policy explains the information RuleNet needs to access, how it is processed and stored, the Android permissions used, and the choices available to you. RuleNet is designed as a local firewall. Its main network-control functions operate on your device without an account or a remote VPN server operated by Krepel Studio.
To provide its functions, RuleNet processes the following information locally:
Installed applications: application names, icons, package identifiers, and associated Android application identifiers, to display your apps and apply rules to the correct app.
Your firewall settings: the selected Wi-Fi-only, mobile-data-only, or no-internet rule for each configured app, whether that rule is enabled, and other information needed to maintain your configuration.
Network state: available Wi-Fi and mobile networks, their connection status, and related Android network information needed to apply the chosen restriction.
Temporary connection information: network packets and technical connection details, including IP addresses, ports, protocols, and DNS-related information when necessary to enforce the active rule.
App preferences: your selected language, theme, vibration setting, onboarding completion, and relevant permission and service states.
Purchase entitlement: limited information about whether Lifetime Pro has been purchased or restored through Google Play.
The installed-app list, firewall rules, and traffic information are used for RuleNet's operation on your device. They are not uploaded to Krepel Studio's servers. RuleNet does not create an account or build a browsing profile from this information.
RuleNet uses Android's VpnService to apply network restrictions to selected applications. When you activate a rule, Android may ask you to approve a local VPN connection.
The local VPN processes relevant network traffic in device memory so that RuleNet can allow a connection over the selected network or block it. RuleNet does not operate a remote VPN server, proxy, or traffic-collection service. It does not transmit your network packets, browsing history, DNS logs, or lists of visited destinations to Krepel Studio.
RuleNet does not keep a history of network packets or DNS requests. It does not install its own security certificates, intercept or decrypt HTTPS content, or change your country or public IP address through a remote VPN server.
When a connection is allowed, the traffic is sent over the applicable Wi-Fi or mobile network to the destination requested by the other application. The destination service, that application, your network provider, and the operating system may process information under their own terms and privacy policies. RuleNet does not control those third parties' data practices.
Android may display a VPN indicator and a foreground-service notification while local protection is active. Another VPN generally cannot operate simultaneously in the same Android user profile. Disabling or revoking the VPN, or force-stopping RuleNet, can interrupt protection and may restore ordinary network access.
Depending on your Android version and the active features, RuleNet uses the following permissions and system capabilities:
VPN service authorization: to create and operate the local firewall. The VPN service is protected by Android's BIND_VPN_SERVICE mechanism, and user authorization is requested through the Android VPN confirmation screen.
Installed-app visibility (QUERY_ALL_PACKAGES): to list available installed applications and let you configure their network access individually.
Internet and network state (INTERNET, ACCESS_NETWORK_STATE, CHANGE_NETWORK_STATE): to identify available networks and route allowed connections through the appropriate network.
Foreground service: to keep enabled network restrictions operating while the RuleNet interface is not open, with the applicable Android foreground-service declarations.
Notifications (POST_NOTIFICATIONS where applicable): to show information about an active service and its status, subject to your Android notification settings.
Device startup (RECEIVE_BOOT_COMPLETED): to attempt to restore previously enabled protection after a restart when Android permits it; this does not override your decision to disable protection.
Vibration (VIBRATE): to provide optional interface feedback when you enable it in RuleNet's settings.
Google Play Billing: to offer and restore the optional one-time Lifetime Pro purchase.
On Android versions that require additional permission for applicable local-network connections, RuleNet may request that permission when needed and explain its purpose.
RuleNet does not require Accessibility Service, access to notification content, device location, contacts, camera, microphone, SMS, call logs, or unrestricted access to personal files for its core firewall functionality. You can manage or revoke applicable permissions in Android settings. Some restrictions cannot operate without VPN authorization.
RuleNet offers an optional Lifetime Pro upgrade as a one-time purchase through Google Play. Google Play processes payments and maintains transaction records under Google's own policies.
To provide or restore Pro access, RuleNet may receive limited purchase-related information from Google Play, such as the product identifier, purchase status, purchase token, and acknowledgment state. RuleNet uses this information only to determine your purchase entitlement.
Krepel Studio does not receive your full payment-card information through RuleNet and does not operate a separate payment-processing server for the App. For details about Google's handling of data, see https://policies.google.com/privacy.
RuleNet does not display advertisements in either the Free or Pro version. It does not use Google AdMob, an advertising SDK, or an advertising identifier for personalized ads.
The approved RuleNet configuration does not include third-party analytics, advertising trackers, or a cloud traffic-monitoring service. Your installed-app list and network activity are not used for advertising, marketing profiles, or sale to data brokers.
We do not sell your personal information or share your locally processed firewall rules, installed-app inventory, DNS queries, or packet contents with advertisers or data brokers.
RuleNet uses Android system services to provide its firewall functionality and Google Play Billing for purchases. Google may independently process information needed to operate Android, Google Play, and purchase services under its own privacy policies. Applications whose connections you allow may continue to communicate with their intended external services.
If you voluntarily contact Krepel Studio by email, we receive the information you include in your message and use it to respond to your request or provide support.
RuleNet stores your selected application rules and preferences in its private application storage on your device. Temporary network packets and connection details are processed in memory and are not retained as traffic or DNS logs.
Locally stored settings remain until you change them, clear RuleNet's application data, or uninstall the App, subject to Android's device and backup behavior. RuleNet does not provide its own cloud synchronization or account-based backup service.
Google Play manages its own purchase records according to Google's policies. If you contact us by email, support correspondence may be retained as needed to handle your request and applicable legal obligations. You may request deletion of information you have voluntarily sent to us by contacting Krepelstudio@gmail.com, subject to any legal retention requirements.
RuleNet is designed to keep its firewall settings in Android's application-private storage and to process network traffic locally. It does not upload network packet logs or install certificates to inspect secure connections.
No application or network system can guarantee absolute security. The security and privacy of connections that reach other applications' servers also depend on those applications, their encryption practices, your network, and Android.
You can choose which applications to configure, change a saved rule, turn a rule on or off, or revoke RuleNet's VPN authorization in Android settings. You can also change the App's language, theme, and vibration preferences.
You can remove locally stored RuleNet information by clearing the App's data or uninstalling it. This does not automatically delete Google Play purchase records or email messages you previously sent to us.
Depending on your location, privacy laws may give you additional rights concerning personal information held by Krepel Studio. You can contact Krepelstudio@gmail.com to ask about access, correction, or deletion of information you have provided directly to us. We cannot access or retrieve data that remains only on your device.
RuleNet is a general-purpose network-control tool and is not specifically directed at children under 13 or the applicable age of digital consent. We do not knowingly collect children's personal information through a RuleNet account or developer-operated traffic server. If you believe you have provided us with a child's personal information in a support message, please contact us.
We may update this Privacy Policy when RuleNet's functionality, permissions, integrations, or legal requirements change. The updated version will show a revised effective date. We encourage you to review the policy periodically.
