NoDial: Block Outgoing Calls

■ Block the numbers you've decided not to call
NoDial is an Android app that physically stops calls your willpower alone can't. Add the number of someone you've decided to stop contacting, and calls to that number simply won't go through — no need to delete the contact.

■ Not a "contact vault." An outgoing wall.
NoDial doesn't work like apps that hide or lock your contacts. It uses Android's built-in call redirection system (CallRedirectionService) to intercept and stop outgoing calls to any number you've registered. Whether you remember the number by heart or write it down somewhere else, a call to a blocked number simply won't connect.

■ Built with no "undo" button
There's no button in NoDial to remove a number once it's been added. That's by design — so a weaker moment can't talk you out of it. If you want to unblock a number, you'll need to either close your account from within the app or uninstall the app entirely. Closing your account deletes your account, registered numbers, and history immediately and permanently. The door out is always there — it just requires a clear-headed decision to walk through it.

■ Pricing: your first number is free, always
NoDial lets you block one phone number and use every feature, completely free, with no payment information required. If you want to block a second number or more, you'll need Premium ($4.99/month, auto-renewing), which removes the limit on how many numbers you can block. Payment is handled through Google Play Billing, and you can cancel anytime from your Google Play subscriptions page. Refunds are not prorated and follow Google Play's standard refund policy.

■ Emergency numbers are never blocked
911, 999, 112, and other major emergency numbers are excluded at the system level from the very start — they can never be added as blocked numbers. Even if you try to register one by mistake, the app will refuse it. Your ability to call for help in an emergency is always protected.

■ We don't know who you are
NoDial is built around strict privacy by design. It never collects personal information like your email address, password, name, or contacts. The only things stored on our server are a device-generated identifier (a UUID) created when you open the app, and an optional nickname you choose. The phone numbers you register are hashed before they're ever sent to our server, so we have no way of knowing who you are or which numbers you've blocked.

■ Switching phones or uninstalling
NoDial is tied to your device, so there's no account transfer when you switch phones. On a new device, you'll set up a new account and re-add your blocked numbers. If you had a Premium subscription on your old device, note that closing your account or uninstalling the app does not automatically cancel your Google Play subscription. Before switching devices, we recommend canceling your subscription from the Google Play subscriptions page on your old device first.

■ NoDial might not be for you if:
• You want to block incoming calls (NoDial only blocks outgoing calls — you'll still receive incoming calls normally)
• You need formal invoices for business accounting (Google Play automatically issues a purchase receipt, but we don't provide separate business invoices)

■ Requirements
• Android 10 (API level 29) or higher
• A device that supports call redirection (CallRedirectionService)
• An internet connection (required for registration and sync)
