This Privacy Policy explains what the Android app Dial Deck (package name com.himavarshan.dialdeck, "the app") accesses on your device and how it is handled. The app is published by Himavarshan Reddy ("the developer", "I", "me"). You can contact me at himavarshanreddy@gmail.com.
Dial Deck can be your phone's default Phone app. It then shows the screen for incoming and outgoing calls, lets you answer, decline, hold, mute and end calls, shows your recent calls (Recents), favourites and contacts, notifies you of missed calls, and can block numbers. Its home-screen widget shows your favourites and, while Dial Deck is your Phone app, your recent calls; tapping a name calls that person, or opens a chat in WhatsApp or a new message, depending on the mode you chose. Calls themselves are carried by your phone's own calling service and your mobile carrier.
| Permission / access | What it is used for |
|---|---|
| Call log (READ_CALL_LOG, WRITE_CALL_LOG) | Only while Dial Deck is your default Phone app: showing Recents in the app and widget, missed calls and the calls with a contact. It changes your call history only when you delete calls or clear your history, and to mark missed calls as seen. |
| Contacts (READ_CONTACTS, WRITE_CONTACTS) | Showing names, numbers and photos. It changes a contact only when you ask: starring or unstarring a favourite, or choosing a ringtone for that contact. |
| Phone (CALL_PHONE, READ_PHONE_STATE) | Placing calls, and knowing when a call ends so Recents refresh. No phone number, IMEI or other identifier of your phone is read. |
| Calls (as the default Phone app) | Android hands Dial Deck your calls so it can show the call screen and act on your taps. Optional call screening checks incoming numbers against your contacts on the phone if you turn on blocking of unknown or private callers. |
| Notifications, full-screen alerts, wake lock | Showing incoming, ongoing and missed calls; showing the call screen over the lock screen; turning the screen off when the phone is at your ear. |
| Start at boot (RECEIVE_BOOT_COMPLETED) | Keeping the widget up to date after a restart. No data is accessed. |
All of the information above is read and used only on your phone, to show it to you and to do what you tap. Numbers you block are kept in Android's own blocked-numbers list. If you choose to message someone, Dial Deck hands their number to WhatsApp or your Messages app, whose own privacy policies then apply. "Reply with a message" on a ringing call is sent by your phone's own messaging service. If you tap Share contact (or Share number), Android's share sheet opens and Dial Deck hands that one contact card, or number, to the app you pick; nothing is shared unless you choose an app.
Your settings (appearance, colour, widget choices), the order of your favourites, the number you chose for each contact, your quick replies, and a short diagnostic log of what the call screen and call engine did, in which every phone number is shortened to its last two digits. This stays in the app's private storage and is removed when you uninstall the app. The app does not use cloud backup.
Dial Deck does not collect or share your personal data. It has no internet permission, so it cannot send anything by itself.
Test reports (only if you send one): Settings › Help › Send test report opens your own email app with a report addressed to me. It contains the diagnostic log described above, crash details, your phone model, Android version and the app version. Every phone number in it is shortened to its last two digits; it contains no names, no full numbers and no call history. Nothing is sent unless you press send in your email app. I use reports only to fix problems. Send feedback works the same way: it opens your email app, and only what you write is sent.
Data on your phone stays until you delete it or uninstall the app. Test reports and feedback emails you send are kept only as long as needed to fix the problem; email me and I will delete them.
You can stop using Dial Deck as your Phone app at any time (Android Settings › Apps › Default apps › Phone app); it then stops reading your call log. You can withdraw any permission in Settings › Apps › Dial Deck › Permissions, or uninstall the app, which removes everything it stored.
Your data stays in Android's protected storage for the app and in Android's own call log, contacts and blocked-numbers lists. Because the app never transmits data, there is no server or account that could be breached.
The app is not directed at children under 13 and does not knowingly collect information from anyone.
Depending on where you live, you may have rights to access or delete personal data. Since the app collects nothing, there is no data held about you, except a test report or email you chose to send, which I will delete on request.
If this policy changes, the updated version will be posted on this page with a new "Last updated" date.
