Privacy Policy
Summary: Nkall works on your phone. NK Suite does not run servers for Nkall and does not collect, upload, sell or share your contacts, call history, messages or personal data. Nkall has no ads, no analytics and no tracking, and it does not use the internet.
1. Who we are
Nkall is a phone dialer, contacts and SMS app made by G S Nithin Krishna under the NK Suite name. Questions about this policy: support@nksuite.app.
2. Data Nkall uses, and why
Everything below is read and processed on your phone only.
| Data / permission | Why Nkall uses it |
|---|---|
| Contacts | To show, search, edit, merge and back up your contacts, and to show where each one is saved. |
| Accounts on your phone | Only the names of accounts that can hold contacts (for example your Google email) and whether each one's contact sync is on, so you can choose which to show. |
| Phone, phone state and call log | To place and answer calls as your default phone app, show your recent calls and show the caller's name. Used only while Nkall is your default phone app. |
| SMS and MMS | To receive, show, sort and send your texts and pictures, only while Nkall is your default SMS app. Message sorting (OTP, transactions, spam and so on) happens on your phone. |
| Call screening | To block spam and hidden numbers before they ring, when you allow it. |
| Microphone | Only while you use voice search, so your phone can turn your speech into text. Nothing is recorded or kept. |
| Alarms and full-screen alerts | To ring reminders on time and show the incoming call, alarm and emergency screens over the lock screen. |
| Notifications | To show calls, missed calls, texts and reminders. |
| Light sensor and screen brightness | Only while Auto App Theme is on. Readings are used instantly and never saved. |
3. Spam warnings, caller ID and Insights
Suspected spam: when a number that is not in your contacts calls, Nkall checks your network's number check, the caller name your network sends and this phone's call history to warn you. The check happens on your phone; nothing is sent anywhere.
Caller ID: when your phone network sends a caller's registered name with a call (in India, the CNAP name), Nkall shows it for numbers that are not in your contacts and remembers it only on your phone. Nkall never looks numbers up on the internet. You can clear these names in Organise.
Insights: your call, text and contact statistics are worked out on your phone each time you open them and are never saved or sent.
4. What Nkall stores on your phone
- Settings: App Lock, theme, swipe actions, chosen contact sources, speed dials, contact tags, archived contacts, the last number you dialled and your MY INFO details.
- Call history copy: so your full call history can be saved as a PDF, Nkall keeps its own copy of your call log (number, name, type, date and length), including calls you later delete from the phone.
- Contact copy for Restore and Bin: each contact as it is now, its last 2 earlier versions, and deleted contacts for 30 days.
- Reminders, call notes, family groups, emergency contacts and calling-card pictures. Ringtones you make from a song are saved in the Ringtones/Nkall folder.
Nkall never uploads any of this to NK Suite. If your phone's own backup (Android backup to your Google account) is turned on, Android may include Nkall's app data in that encrypted backup, which is stored in your own Google account under Google's privacy policy. NK Suite cannot see or access it.
5. What Nkall changes
Nkall changes your contacts only when you ask it to: when you back up contacts into an account, edit or delete a contact, merge duplicates, restore a contact or an earlier version of it, or set a ringtone for a person or a group.
6. Backups
Contact backups happen only when you start them:
- Google account: contacts are copied into the account you choose, and Google syncs them under Google's own privacy policy.
- SD card: a .vcf file is saved in "Nkall Backups" on the memory card, after you allow it.
- .vcf file: saved in Documents/Nkall or wherever you choose.
Anyone who has a .vcf file can read the contacts in it, so keep backup files somewhere safe.
7. App Lock and voice search
App Lock uses Android's own screen lock. Your fingerprint, face, PIN, pattern or password are checked by Android; Nkall never sees or stores them.
Voice search uses your phone's speech recognition service (on the phone itself when your phone supports it), provided by your phone maker or Google under their own privacy policy. Nkall only receives the text and keeps no recording.
8. Other apps
If NDriveONE File Manager (another NK Suite app) is installed, Nkall can use it to pick a picture or choose where to save a file such as your call history PDF. The file goes straight from Nkall to NDriveONE on your phone; nothing is uploaded. WhatsApp, email apps and the accounts on your phone work under their own terms.
9. Data sharing and selling
Nkall does not share or sell any data. MY INFO details leave your phone only when you share them yourself, and only the ones you tick.
10. Contacting us
If you email us from Contact Us, we receive only what you choose to send (your email address, message, any screenshot you attach and the app version) and use it only to reply to you.
11. Children
Nkall is not directed at children under 13 and does not knowingly collect any of their data.
12. Your choices and deletion
You can allow or remove any permission at any time in Menu > App Settings > Permissions, or in your phone's settings. Uninstalling Nkall removes its data from your phone. Backups you saved stay where you saved them until you delete them.
13. Changes
If this policy changes, the updated version will be posted on this page and shown in the app, with a new effective date.
