Terms of Service

Last updated: 2026-07-08 / Established by XTV LLC

These Terms of Service ("these Terms") govern the conditions of use of the outgoing-call blocking application "NoDial" ("the Service") provided by XTV LLC ("we" or "the Company"). By using the Service, you are deemed to have agreed to all provisions of these Terms.

Article 1 — Scope of Application

1. These Terms apply to all matters relating to the use of the Service between us and the user.
2. If you do not agree to these Terms, you may not use the Service.
3. Any individual rules, guidelines, or other policies posted by us in connection with the Service ("Supplemental Rules") shall form part of these Terms. In the event of any conflict between these Terms and Supplemental Rules, the Supplemental Rules shall prevail.

Article 2 — Service Description

1. The Service is an application that uses Android OS's Telecom Framework to technically block outgoing calls to phone numbers that the user registers in advance.
2. The main features of the Service are as follows:
   1. Blocking of outgoing calls to registered numbers (via CallRedirectionService.cancelCall)
   2. A pricing model in which the first number is free, with a monthly-subscription Premium plan required only to block a second number or more (see Article 4)
   3. In-app display of the call attempt history for registered numbers
3. The Service is designed as a "tool that respects the user's willpower" and does not coerce the user.

Article 3 — Account and Authentication

1. To use the Service, users must install the Service's application on their device and create an account.
2. We do not collect personal information such as email addresses, passwords, names, phone numbers, or home addresses when creating an account. The account identifier is a unique identifier (UUID) generated on the user's device.
3. Users may optionally set a nickname, which is used for display purposes only.
4. Possession of a device on which the Service application is installed shall be deemed sufficient evidence of identity. We may treat any operations performed from that device as operations by the account holder.
5. The Service does not provide an account transfer feature. If access to an account is lost due to a device change, damage, or loss, previously registered numbers, history, and other data cannot be recovered (see Article 6).

Article 4 — Fees and Payment

The Service is operated under two pricing plans: the Free Plan and the Premium Plan.

1. Free Plan
   1. Without any additional registration or entry of payment information, users may register up to one phone number to block and may use all features of the Service.
   2. Users who were already using the Service before the effective date of these Terms and had already registered two or more phone numbers may continue to use, as their Free Plan allowance, the number of registrations they held at the time of migration.
2. Premium Plan
   1. To register a second phone number to block or more, the user must subscribe to the Premium Plan.
   2. The Premium Plan is priced at ¥500 per month (tax included) where displayed for Japan, or $4.99 per month where displayed for other regions. The displayed price is determined by Google Play based on the device's configured region.
   3. Subscribing to the Premium Plan removes the limit on the number of phone numbers that may be blocked.
   4. The Premium Plan is an auto-renewing subscription offered through the Google Play Billing system provided by Google LLC. The payment method and billing process are governed by Google Play's terms.
   5. The Premium Plan automatically renews for the same term and price unless the user cancels at least 24 hours before the next renewal date.
3. Cancellation
   1. The Premium Plan may be canceled at any time from the "Subscriptions" section of the Google Play app. The Service provides an in-app link to the Google Play subscription management screen.
   2. Even after cancellation, the Premium Plan remains active until the end of the period already paid for. No prorated refunds are issued.
4. Handling After Cancellation or Expiration
   1. When the Premium Plan's paid term expires, the plan automatically reverts to the Free Plan.
   2. For registered numbers beyond the Free Plan allowance (one number, or the number of registrations held at the time of migration as described above), the blocking feature is temporarily suspended. The registration data for these numbers is not deleted and remains stored.
   3. If the user subscribes to the Premium Plan again, the suspended blocking feature is promptly restored.
5. Refunds
   1. Refunds are handled in accordance with Google Play's refund policy. We do not provide refunds independently of Google Play.
6. Receipts and Purchase History
   1. Receipts and purchase history for the Premium Plan are issued by Google Play and can be viewed by the user through the Google Play app. We do not issue receipts independently.

Article 5 — Withdrawal and Uninstallation

1. Withdrawal (from within the app)
   1. Users may withdraw from the Service at any time from the settings screen within the app.
   2. Once the withdrawal process is complete, the user's account, registered numbers, call attempt history, and other data are deleted immediately. This deletion is irreversible, and the data cannot be recovered afterward.
   3. If a user subscribed to the Premium Plan withdraws from the Service, the Google Play subscription is not automatically canceled. To stop the subscription, the user must separately cancel it from the Google Play app's subscription management screen. We display a warning to this effect on the withdrawal screen within the app to alert users.
   4. If a user withdraws without canceling the Google Play subscription, the subscription will continue to auto-renew and charges will continue to be incurred. We are not liable for any disadvantage this may cause the user.
2. Uninstallation
   1. If the user deletes the Service application from their device, our server will detect the cessation of the periodic heartbeat signal from the application.
   2. If no communication is received from the device for 5 consecutive days after the heartbeat ceases, the account, registered numbers, history, and other data are automatically deleted (see Article 6).
   3. As with withdrawal above, uninstalling the app alone does not automatically cancel a Google Play subscription; charges will continue to be incurred. The subscription can still be canceled from the Google Play app's subscription management screen even after uninstallation.

Article 6 — Device Changes and Lost Devices

1. The Service does not provide an account transfer feature. In the event of a device change, damage, or loss, the user must create a new account on the new device and re-register the numbers to block.
2. The old device's account will be deleted either through the withdrawal process described in Article 5 or by the automatic deletion triggered when no communication is received from the old device for 5 days.
3. If the user had subscribed to the Premium Plan on the old device, that subscription is not automatically canceled by deletion of the account. Before giving up the old device, users are strongly encouraged to cancel the subscription from the Google Play app's subscription management screen.
4. For users planning a device change, the recommended approach is to first create a new account and re-register numbers on the new device, then withdraw from the Service on the old device and cancel any active subscription there.

Article 7 — Emergency Numbers

1. The Service is designed so that major emergency numbers in various countries — including 110, 119, 118, 911, 112, and 999 — cannot be registered by the user and, even if somehow registered, are automatically excluded from blocking.
2. In the unlikely event that an emergency call is blocked by the Service, we accept no liability whatsoever for any damage arising from such an event.
3. Users should use alternative means of communication (public phones, another person's device, etc.) in emergencies and must not rely solely on the Service.

Article 8 — Personal Use Restriction

1. The Service is designed exclusively for personal use. Use by corporations or organizations, use for business purposes, and use for expense reimbursement purposes are outside the intended scope of the Service.
2. We do not issue receipts, qualified invoices, or invoices of any kind.
3. If you wish to use the Service on a corporate basis, please contact us separately.

Article 9 — Prohibited Conduct

Users must not engage in any of the following conduct when using the Service:

1. Any act that violates laws, these Terms, or public order and morals
2. Any act that infringes the rights of other users, third parties, or the Company
3. Registering a third party's phone number for the purpose of harassment, stalking, or any other improper purpose
4. Any act that damages the reputation, honor, or brand of the Company
5. Reverse engineering, modifying, copying, or redistributing the Service
6. Exploiting vulnerabilities in the Service
7. Evading payment through unauthorized means
8. Any other conduct that the Company deems inappropriate

Article 10 — Intellectual Property Rights

1. All intellectual property rights in the content, software, trademarks, logos, and other materials displayed in connection with the Service belong to us or to third parties who have licensed such rights to us.
2. Users must not infringe these intellectual property rights when using the Service.

Article 11 — Disclaimer and Scope of Warranty

1. We make no warranty of any kind regarding the completeness, accuracy, usefulness, or fitness for a particular purpose of the Service.
2. Because the Service operates via Android's telephony control API (Telecom Framework), the following limitations exist:
   1. Customizations by device OEMs or battery optimization settings may prevent the Service from launching or limit its functionality.
   2. Internet-based calls such as LINE calls and WhatsApp calls are not covered.
   3. Calls made from a different device, a public phone, or another person's device cannot be blocked.
   4. The Service normalizes numbers to E.164 format where possible to handle variations such as withholding caller ID or formatting differences (e.g., +81 format vs. leading-zero format), but cannot guarantee complete matching in all cases.
3. We accept no liability for any damage arising from the limitations described above or from the use or inability to use the Service.
4. Our liability shall in no event exceed the total amount paid by the user to us during the 12 months immediately preceding the event giving rise to the liability.

Article 12 — Service Changes and Termination

1. We may change the content of the Service or discontinue providing it, provided that we give users advance notice.
2. If we discontinue the Service, we will notify users before the termination date. Users subscribed to the Premium Plan should cancel it from the Google Play subscription management screen before termination. From the termination date, all user accounts, registered numbers, history, and related data will be deleted.

Article 13 — Changes to These Terms

1. We may amend these Terms.
2. When amendments are made, we will notify users of the content and effective date through in-app notifications. For changes to fundamental matters such as the billing structure or methods of withdrawal, we will obtain renewed consent from users.

Article 14 — Mail-Order Sales and Right of Withdrawal

1. The Service constitutes mail-order sales as defined under the Act on Specified Commercial Transactions (Japan).
2. The Premium Plan offered through the Service is digital content and a digital service that becomes available for use immediately upon completion of payment. Owing to this nature, the Premium Plan is not subject to the statutory right of withdrawal (cooling-off period) under the Act on Specified Commercial Transactions.
3. To cancel the Premium Plan mid-term, users may cancel at any time from the Google Play app's subscription management screen. Cancellation takes effect from the next renewal date, and no prorated refund is issued for the period already paid for.
4. Withdrawal from the Service as a whole shall be effected through the withdrawal process described in Article 5.

Article 15 — Minors

1. If a user is a minor (under 18 years of age), the use of the Service requires the consent of a parent or legal guardian.
2. If it becomes apparent that a minor has used the Service without the consent of a parent or legal guardian, we may accept a request for cancellation of the contract from the minor or the parent or legal guardian.

Article 16 — Governing Law and Jurisdiction

1. These Terms are governed by the laws of Japan.
2. All disputes arising from or in connection with the Service or these Terms shall be subject to the exclusive jurisdiction of the Tokyo District Court as the court of first instance.
