Terms of Service

Last Updated: October 2, 2026 | Effective Date: October 2, 2026

Section 1 (Purpose)

These Terms of Service ("Terms") govern the terms and conditions under which SOV ("Company") provides the Android application 'OneTap NetFilter' ("Service"), and define the rights, duties, and responsibilities between the Company and users.

Section 2 (Service Provision & Features)

The Service provides local on-device network security and privacy protection features, including:

  1. Android VpnService-based local DNS query inspection and local loopback filtering.
  2. Real-time proactive blocking of known malicious domains, phishing sites, and trackers.
  3. User-customizable domain allowlist and blocklist management.
  4. Local threat statistics and filtering diagnostic logs.

Section 3 (Paid Services, Subscriptions & Free Trials)

  1. Premium Membership Options: The Service offers essential features for free and enhanced security features through auto-renewing subscriptions and a one-time lifetime pass.
  2. Zero-Friction 3-Day Free Trial:
    1. To allow seamless evaluation of premium features, the Company offers an instant 3-day (72-hour) free trial upon first activation, requiring no account creation and no payment method registration.
    2. This 3-day trial is strictly limited to one (1) per physical device.
    3. Repetitive abuse, including repeated reinstallation, cache clearing, or identifier spoofing to bypass the trial limit, is automatically detected and blocked by our cloud verification system.
    4. Because no payment method is collected for this trial, you will NEVER be automatically charged when the 3-day trial expires; the service simply transitions into an expired state.
  3. Subscription Pricing & Billing:
    1. Subscription prices, currencies, and billing intervals are determined as displayed on the in-app subscription screen and Google Play checkout sheet prior to confirmation, and are charged to your designated payment method upon approval.
    2. Unless a promotional trial is explicitly specified, billing commences immediately upon subscription confirmation.
    3. If a promotional trial is applied, your subscription will automatically roll over into a paid subscription at the stated regular price upon expiration of the trial period unless canceled beforehand.
  4. Auto-Renewal & Recurring Billing:
    1. Subscriptions automatically renew on each billing cycle unless canceled by the user before the renewal date.
    2. The exact price, currency, and renewal period are clearly displayed in the in-app subscription screen and Google Play checkout sheet prior to confirmation.
  5. Cancellation & Avoidance of Charges:
    1. You may cancel your subscription at any time.
    2. To avoid being charged for the next billing cycle, you must cancel the subscription at least 24 hours before the current period ends.
    3. How to Cancel: Open the Google Play Store app > tap your Profile icon (top-right) > Payments & subscriptions > Subscriptions, select 'OneTap NetFilter', and tap [Cancel subscription]. Uninstalling the app does not automatically terminate or cancel your subscription.
  6. Refund Policy: In-app purchases and subscription refunds are governed directly by Google Play Store Refund Policies and applicable consumer protection laws.

Section 4 (Disclaimer of Warranties & Limitation of Liability)

  1. The Service operates based on open-source community filter lists. We do not guarantee 100% detection or blocking of all potential online threats or trackers.
  2. The Company shall not be held liable for any communication disruption or service access restrictions caused by user-configured domain blocking or allowing rules, absent willful intent or gross negligence.
  3. The Company is not liable for temporary service interruptions arising from factors beyond reasonable control, such as carrier outages, hardware failures, or OS system updates.

Section 5 (User Obligations)

Users agree to comply with applicable laws and these Terms. Users shall not decompile, reverse-engineer, or misuse the Service for unlawful activities or infringe on the rights of third parties.

Section 6 (Intellectual Property)

All trademarks, user interface designs, and proprietary source code related to the Service are the exclusive intellectual property of the Company. Third-party open-source filter lists (such as AdGuard DNS Filter) and open-source libraries belong to their respective copyright holders and are licensed under their applicable open-source terms.

Section 7 (Amendments & Governing Law)

The Company reserves the right to amend these Terms in accordance with applicable laws. These Terms shall be governed by and construed in accordance with the laws of the Republic of Korea.
