Privacy notice

OnRing is a service of Mill Standard, Inc. Contact: info@millcorn.com.

Account and calling information

We process your phone number to verify ownership, sign you in and restore your account. We process destination numbers and call records, including time, duration and charges, to connect calls, maintain your history, calculate your balance and protect the service.

Device permissions

Contacts access is optional; you can enter a number manually. Contact names stay on your device. If you enable OnRing contact discovery, phone-number hashes are transmitted for a real-time match against other users who have allowed discovery. Lookup lists and relationship graphs are not stored. Only your own phone hash and discovery preference are retained until you disable discovery or delete your account. Microphone access is used for call audio. You can change these permissions in your device settings.

Payments and mobile top-ups

Our payment processor handles payment details. OnRing keeps purchase and transaction references to credit your balance, manage bundles, handle refunds and avoid duplicate payments. For mobile top-ups, the recipient number and selected product are processed to deliver the recharge.

Welcome trials and invitations

Welcome trials and optional invitations use a random installation identifier and its hash to prevent repeated rewards. A one-way phone digest prevents repeated welcome trials after account deletion. We retain invitation attribution and restricted bonus accounting records, and use payment-instrument fingerprints supplied by our payment processor for fraud prevention. We do not access advertising identifiers or track you across other companies’ apps. Share invitations only with people who expect them.

Service providers

We use providers for hosting, number verification, call delivery, payment processing and mobile top-ups. They receive the information needed to perform those services.

Retention and your choices

You can request account deletion in the app under Account Delete account. New calls and purchases stop while active calls, payments, recharges and subscription cancellations are completed. We then remove personal account and contact-number data and revoke sessions. A pseudonymous verification counter is retained for up to 24 hours to prevent SMS-limit abuse. Restricted financial records may be retained for accounting, disputes and legal obligations. Contact us about access, correction or retention.
