Mobile App Privacy Notice.

This Mobile Privacy Notice supplements Rozper's main Privacy Policy for people who install and use the Rozper mobile app (our softphone and messaging client for calls, SMS, and video meetings on iOS and Android).

Websites and desktop apps mostly collect data you type in. A mobile app is different: it can ask the operating system for access to hardware and on-device data — your microphone, contacts, camera, and location — and it runs with a background process that can send you push notifications. This notice explains, specifically, what the mobile app asks for, why, and how you stay in control. Where this notice is silent, the main Privacy Policy continues to apply.

We wrote this notice separately, rather than folding a short paragraph into the main policy, because permission prompts are the moment most people actually think about mobile privacy — you get a system dialog asking to allow or deny, and we want the answer to “why does it need that” to be easy to find at exactly that moment.

The app only requests an OS-level permission when a feature you use needs it, and only at the point you first try to use that feature. You can decline any permission and still use the parts of the app that don't depend on it.

• Microphone. Required to place or receive a voice call, or to speak during a video meeting. Audio is only captured while you are actively on a call or meeting.
• Contacts. Optional. If you grant access, the app can match phone numbers in your address book so incoming calls show a name instead of a raw number, and so you can dial a contact directly. Contact data used for this matching is processed on your device wherever technically feasible.
• Camera. Required only for video meetings or sending photo/video messages. The camera is not accessed in the background or outside an active session you started.
• Push notifications. Used to alert you to incoming calls, messages, or missed-call summaries when the app is not in the foreground. You can disable categories of notification individually in-app or at the OS level.
• Location. Not used for advertising or general tracking. Where the app requests location, it is to support emergency-calling compliance in jurisdictions that require a caller's location to be made available to emergency services, or equivalent regulatory obligations tied to placing calls from a mobile device. If your plan or region does not require this, the app does not request location.

We do not request any permission we cannot tie to a specific, named feature above, and we do not sell the data obtained through these permissions. If a future release adds a feature that needs a new permission, we will prompt for it at the time you use that feature and update this notice to describe it.

Separate from the permissions above, the app collects a smaller set of technical data automatically, similar to most mobile applications:

• Device identifiers. App instance identifiers, device model, OS version, and push notification tokens, needed to route notifications and calls to the right device.
• Crash and diagnostic logs. Automatically generated when the app crashes or a call fails to connect, so our engineering team can fix the underlying issue. These logs are scoped to app behaviour, not the content of your calls or messages.
• App usage analytics. Aggregate information such as which screens are opened and how often features are used, so we can prioritise what to improve. We use this in aggregated or de-identified form wherever feasible.

Call and message content itself is handled under the same rules as the main Privacy Policy: it is processed on behalf of the customer account the app is signed into, under that customer's instructions.

Every permission described in Section 2 is controlled by your device's operating system, not by Rozper directly, which means you can review or revoke it at any time without contacting us:

• iOS. Settings → Rozper → toggle Microphone, Contacts, Camera, Notifications, or Location individually.
• Android. Settings → Apps → Rozper → Permissions, with the same set of toggles, or long-press the app icon → App info → Permissions.

If you revoke a permission the corresponding feature will stop working as expected — for example, revoking Microphone access means you will not be able to speak on a call — but the rest of the app continues to function. Uninstalling the app removes locally cached data and stops all on-device data collection described in Section 3 going forward.

The Rozper mobile app is a business communications tool. It is not directed to children, and it is not designed, marketed, or intended for use by anyone under 16. We do not knowingly collect personal information from children through the app. If you believe a child has an account or has otherwise provided us with personal information, contact privacy@rozper.com and we will investigate and delete it as appropriate.

This notice only adds mobile-specific detail on permissions, device data, and OS-level controls. Everything else — who we are, how long we retain data, your access and deletion rights, how we share data with sub-processors, international transfers, and how to contact us — is governed by the main Privacy Policy. If anything here appears to conflict with that policy, the more specific mobile-related term in this notice controls for the mobile app, and the main Privacy Policy controls for everything else.

Does the app listen to my microphone when I'm not on a call? No. Microphone access is only active during an active call or video meeting you initiated or answered.

Do I have to allow contacts access? No, it is optional. Without it you can still dial numbers manually; you just won't get automatic caller-ID name matching from your address book.

Why would the app ever need my location? Only where local law requires a caller's location to be available for emergency-calling purposes from a mobile device. It is not used for advertising, and the app does not request it if that requirement doesn't apply to you.

What happens to on-device data if I uninstall the app? Locally cached data is removed with the app itself, and no further device data described in Section 3 is collected once it's uninstalled.
