    • • To stop SMS messages, reply STOP. For assistance, reply HELP or contact support@radiocheck.app.

    9. SMS COMMUNICATIONS

    Radio Check sends SMS text messages to users who have opted in through our website opt-in form (radiocheck.app/optin) or through the Radio Check mobile app. Message frequency depends on the user's selected check-in cadence (weekly, monthly, quarterly, or yearly). Message and data rates may apply.

    Mobile information (phone numbers) collected by Radio Check will NOT be shared with third parties or affiliates for marketing or promotional purposes. Mobile opt-in data and consent is not shared with any third parties.

    Users can opt out of SMS communications at any time by replying STOP to any message. For assistance, reply HELP or contact radiocheck.app/support.

    10. CONTACTS AND CONTACT MATCHING

    Radio Check lets you optionally find people from your phone Contacts who are already using the app.

    When you choose Find Contacts on Radio Check, we ask for your explicit consent before any upload occurs. If you tap Not Now, no Contacts data is uploaded for matching.

    If you consent, Radio Check accesses contact phone numbers on your device and securely sends normalized phone numbers to our server for one-time matching against existing verified Radio Check accounts.

    We use this matching result only to show which contacts can be invited to your squad. We do not upload names, notes, or full contact cards for storage as an address book, and we do not sell Contacts data.

    You can revoke Contacts permission at any time in iOS Settings for Radio Check.

    In-app location: Unit → Find Contacts on Radio Check.

    11. CHANGES TO THIS POLICY

    We may update this Privacy Policy from time to time. We will notify you of any material changes by posting the updated policy on this page and updating the "Last updated" date.
