CallerOne

Caller One helps you understand incoming calls, manage phone activity and discover local service providers from one focused Android app.

CALLER ID AND CALL TOOLS
• Identify incoming callers when Android’s caller-screening role is enabled and information is available.
• Search a phone number manually before calling back.
• Use the in-app dial pad and call screen when Caller One is selected as your default phone app.
• Review recent calls on your device.
• Open call, SMS, WhatsApp, WhatsApp Business, Telegram and UPI actions through the relevant installed app.

SPAM AND FRAUD CONTEXT
Caller One can show community and system-generated risk context when sufficient reliable evidence is available. Labels are informational—not a guarantee of identity, safety or payment recipient. Always verify sensitive requests and confirm the payee inside your payment app.

CONTACTS AND PROFILES
• Browse your contacts and keep optional profile fields private, public or visible to your contacts.
• Create a personal profile, Digital ID, business, service-provider or job-seeker listing.
• If you separately opt in to contact contribution, eligible saved names and numbers can help improve directory information. Normal contact display stays on your device, and contribution can be stopped.

LOCAL SERVICES WITHOUT EXACT LOCATION
Search by city or approximate nearby area. Providers can list service categories, experience, availability, rates and a service radius. Caller One displays a city or approximate distance—not exact customer or provider coordinates.

USEFUL EXTRAS
• User-enabled floating caller card for caller context over other apps.
• Open supported documents with Caller One from Android’s “Open with” menu. There is no document browser inside the app.
• Reversible account deactivation, permanent data deletion, profile visibility controls and ad privacy choices.

PERMISSIONS AND PRIVACY
Caller One asks for permissions for the feature you choose. Call Log access is used only while Caller One is the default Phone handler. Contacts require Android permission; optional server contribution requires a separate disclosure and consent. Approximate foreground location is used for local services. The floating caller card needs “Display over other apps.” Caller One does not read your SMS inbox or collect background location.

Caller One contains ads. Ads are not shown on the system floating caller card, lock screen or active-call controls. Availability and caller information may vary by country, device, carrier and available evidence.
