Proxy Guard

Skyen Systems ("we", "us", or "our") operates the Proxy Guard mobile application ("Proxy Guard" or the "App"). This Privacy Policy explains how we collect, use, disclose, and protect information when you use the App.

Proxy Guard does not require you to create an account, sign in with email, or provide a password. Premium access is tied to your Apple App Store or Google Play account on your device, not to a separate Proxy Guard profile.

Depending on how you use Proxy Guard, we may collect:

• Device identifier: an anonymous device ID generated on your device to manage VPN configuration, subscription entitlement, and device limits for Premium plans.
• Subscription data: hashed store purchase identifiers, product ID (e.g. premium_weekly, premium_monthly, premium_yearly), renewal and expiry dates, and platform (iOS or Android). We do not receive your full payment card details — billing is handled by Apple or Google.
• VPN service data: server region selection and technical data needed to issue and manage WireGuard VPN configurations (such as assigned client addresses and peer keys). This is required to establish your VPN connection.
• Advertising data: where ads are shown, Google AdMob and its ad partners may collect your device advertising identifier, approximate location derived from IP address (country/region level only), device and app information required to render an ad, and ad interaction data such as impressions and clicks. This is described in full in Section 12 (Advertising).
• Analytics data: app events and usage metrics (for example, screen views, connect/disconnect funnel events, subscription and ad-related events) collected via Firebase Analytics to understand product performance and improve the App. These events are not used to log your browsing history or VPN destination traffic.
• Push notification token: if you allow notifications, a Firebase Cloud Messaging (FCM) token may be stored so we can send engagement reminders (for example, re-engage or connect prompts). You can disable notifications in your device settings.
• App settings: preferences you configure in the App (such as auto-connect or kill switch), stored locally on your device.
• Support communications: information you voluntarily provide when contacting us (such as device model, OS version, and description of your issue).

Advertising and your VPN traffic: Advertising is displayed inside the App interface only. Neither Google AdMob nor any ad partner has access to your VPN traffic, browsing history, DNS queries, or the destinations you connect to. Our no-logs commitment above is unaffected by the presence of advertising in the App.

• Provide VPN connectivity and server selection.
• Validate and manage Premium subscriptions through the App Store or Google Play.
• Enforce device limits and restore purchases on supported devices.
• Serve and measure third-party advertising in the free version of the App.
• Analyze aggregated app usage (via Firebase Analytics) to improve stability and features.
• Operate feature flags and configuration via Firebase Remote Config.
• Send optional engagement notifications if you grant notification permission.
• Maintain security, prevent abuse, and improve the App.
• Respond to support and data-deletion requests.

We use trusted third parties to operate Proxy Guard:

• Google Firebase — Firestore and Cloud Functions for subscription validation and VPN configuration; Firebase Analytics for app event measurement; Remote Config for feature flags (including ad-related switches); and Cloud Messaging for optional engagement notifications. See Firebase Privacy and Google Privacy Policy.
• Google AdMob — third-party advertising served in the free version of the App. In relation to advertising, Google acts as an independent controller under its own privacy policy. See Google Privacy Policy and How Google uses information from apps that use its services.
• Apple App Store / Google Play — in-app purchase and subscription billing. Payment and refund policies are governed by Apple or Google.
• WireGuard — open-source VPN protocol used to encrypt your connection. See wireguard.com.

We do not sell your personal information.

6. Data Storage and Retention

Subscription entitlement records, VPN configuration metadata, and related backend records are stored in Firebase for as long as needed to provide the service or as required by law. Analytics events are processed by Google under Firebase Analytics retention settings. Advertising data is retained by Google in line with its own retention policies. Local app data remains on your device until you uninstall the App or clear app data. You may request deletion of backend records associated with your device — see Data Deletion.

7. Permissions

The App may request access to:

• Internet and network — required to connect to VPN servers, validate subscriptions, load advertising, and sync analytics/configuration.
• VPN / network extension — required to establish the encrypted VPN tunnel on your device.
• Notifications — optional; used for engagement reminders if you grant permission.
• App tracking (iOS) — on iOS, the App may present Apple’s App Tracking Transparency prompt. If you decline, your Identifier for Advertisers (IDFA) is not used for tracking across apps and sites owned by other companies.

8. Children's Privacy

Proxy Guard is not directed to children under 13 (or the minimum age in your region). We do not knowingly collect personal information from children, and advertising in the App is not directed to children. Contact us if you believe a child has provided us data.

9. Your Rights

Depending on your location, you may have the right to:

• Access, correct, or delete personal data we hold about you.
• Object to or restrict certain processing.
• Control tracking and advertising identifiers through your device settings (see Section 12).
• Lodge a complaint with a data protection authority.

To request deletion of backend data, visit Data Deletion or email info@skyensystems.com.

10. Security

We use industry-standard measures including encrypted connections (HTTPS/TLS) for communication with our servers, WireGuard encryption for VPN traffic, and Firebase security rules. No method of transmission or storage is 100% secure.

11. International Transfers

Your data may be processed in countries where our service providers and VPN infrastructure operate, including the United States. Analytics and advertising data may be processed by Google on its global infrastructure. We take steps to protect your information in line with applicable law.

Proxy Guard displays third-party advertisements through Google AdMob, a service provided by Google LLC. Advertising allows us to offer a free tier of Proxy Guard at no cost. Advertising is not shown to Premium subscribers.

12.1 Who Serves the Ads

Ads are served by Google AdMob and its authorised ad partners. In relation to advertising, Google acts as an independent data controller and processes data under its own privacy policy. We do not control which specific ads are shown to you, and we do not receive your advertising identifier from Google for our own marketing databases.

12.2 What Advertising Data Is Collected

When an ad is requested or displayed, the following may be collected:

• Your device advertising identifier (Google Advertising ID on Android; Identifier for Advertisers (IDFA) on iOS, only where tracking is permitted)
• Approximate location derived from IP address (country/region level only)
• Device and app information required to render an ad (device model, operating system version, app version, screen size, language)
• Ad interaction data, such as impressions, clicks, and whether an ad was dismissed
• Limited signals used for frequency capping, ad measurement, and fraud prevention

12.3 Advertising Does Not Affect Our No-Logs Commitment

Ads are rendered within the App interface. Ad networks receive no information about your VPN sessions. Specifically, they do not receive:

• Your browsing history or the websites you visit
• Your DNS queries
• The contents of your internet traffic
• The destination addresses or server regions of your VPN sessions
• Your VPN configuration data, client addresses, or peer keys

The approximate location associated with an ad request is derived from the IP address seen by the ad network at that moment and is used only to serve region-appropriate advertising.

12.4 Personalised and Non-Personalised Ads

On iOS, we may request permission through Apple’s App Tracking Transparency framework before accessing the IDFA for tracking purposes. If you decline, the App does not use the IDFA for cross-app tracking.

Ad serving and personalisation are also subject to Google’s policies and your device advertising settings. You can further limit advertising identifiers through the controls in Section 12.5. Upgrading to Premium removes ads entirely.

12.5 Your Device Controls

• Android: Settings → Privacy → Ads → Delete or reset your advertising ID (wording may vary by OS version)
• iOS: Settings → Privacy & Security → Tracking → turn off “Allow Apps to Request to Track”

12.6 What We Do Not Do

• We do not share VPN activity, connection logs, or traffic data with advertisers — we do not hold this data in the first place
• We do not sell your personal information
• We do not direct advertising to children
• We do not use sensitive personal data for advertising

Removing ads entirely is available by upgrading to a Premium subscription.

13. Changes to This Policy

We may update this Privacy Policy from time to time. We will post the revised version at this URL and update the "Last updated" date above.
