This Privacy Policy applies to the BIG Contacts Android app (Google Play package com.kl8techgroup.thebigcontactbook, product name TheBIGContactBook, version 1.0.0). The app is operated by KL8 Tech Group (ABN 77 923 391 849), NSW Central Coast, Australia.

BIG Contacts is a contact book designed for low vision. The default theme is yellow on true black; you can also choose white on black, black on white, or yellow on deep navy. Text size can be set to 100%, 115%, 130%, or 145%. It shows your contacts with giant text, spaced Australian phone numbers, a full-screen number magnifier, on-device text-to-speech (en-AU), an A–Z jumper, a speed-dial photo row, favourites, and ICE (in case of emergency) contacts. It includes a large dial pad and a list of recent outgoing calls placed from this app only (stored locally, up to 40). It works on phones and tablets; placing calls requires telephony where the device supports it.
BIG Contacts does not ask you to create an account or sign in. The app has no internet permission and does not send your contact data, settings, or call history to KL8 Tech Group or any server we operate. We do not run analytics, crash reporting, or advertising in this app.
Information stays on your phone or tablet, in two places:
Calls and SMS are handed off to your phone's dialer and messaging apps. We do not receive call or message content.
The app requests only what it needs for contact and calling features:
The app does not request location, microphone, call log, internet, or advertising ID permissions.
Voice find and voice message dictation use your phone's built-in speech recognition service (often Google on Android). When you use those features, audio is processed by that provider under its own privacy policy. KL8 Tech Group does not receive your voice audio or transcripts. Other app data is not sent to us; only this system speech feature may involve your device's speech provider.
Spoken readouts (for example, reading a name or number aloud) use on-device text-to-speech with an Australian English voice (en-AU) where available. That processing stays on the device unless your system routes TTS through a network service — check your device settings if you are unsure.
Android backup is allowed for this app. If you use Google or your phone maker's device backup, app data in private storage may be included in your backup to your own account. That is between you and your backup provider; KL8 does not receive it.
There is no account to delete. Deleting a contact inside BIG Contacts removes it from app storage. Uninstalling the app or clearing its storage in Android settings wipes all data stored in app private storage. Contacts the app saved into the phone's address book remain there until you delete them in the Contacts app.
If you email us at ktb@kl8tech.group, we only see what you choose to send in that message.
BIG Contacts is a general contact tool and is not directed at children. We do not knowingly collect personal information from children through the app because we do not receive app data on our servers. If you believe a child has contacted us by email with personal information, write to us and we will delete it.
Under the Privacy Act 1988 (Cth), you may contact us about privacy concerns. Because app data stays on your device, access and correction are usually handled on your phone (for example, in Contacts or app settings). Email ktb@kl8tech.group and we will respond within 30 days. You may also complain to the Office of the Australian Information Commissioner (OAIC).
We may update this policy from time to time. The “Last updated” date at the top of this page shows when it was last revised. Continued use of the app after changes means you accept the updated policy.
