Privacy Policy

Last updated 30 October 2026

CoinKing is run by Randeep Singh (sole trader) (ABN 62 863 175 880), in Australia ("we", "us"). This policy explains what personal information the CoinKing app collects, why, who we share it with and what you can do about it. We handle personal information in line with the Australian Privacy Principles in the Privacy Act 1988 (Cth).

What we collect

Information	Why
Your mobile phone number	To log you in with an SMS code, and to keep to one account per person.
Your first name (optional)	To greet you in the app and show your invites who you are.
Your payout email, and your PayID and the name on your bank account if you choose bank transfer	To send your PayPal payments, gift cards and bank transfers, and to spot the same payout details being used by several accounts.
A device identifier (Android ID, stored only as a one-way hash) and Google Play Integrity results	To stop fraud: emulators, modified apps and multiple accounts on one phone.
Your SIM card's country and whether a VPN is on, when you cash out	To check that cash-outs come from Australia.
Coins earned, offers completed, cash-outs and support requests	To run your wallet, pay you, answer support requests and meet tax record-keeping rules.
Mini-game scores and the words you find	To pay coins for finished games, keep your best scores and stop cheating.
App crash reports	To fix bugs (Firebase Crashlytics).
A notification token, and when you last opened the app	To send you notifications about coins, cash-outs, support replies and occasional news such as new offers or bonus events. You can turn these off in the app.
Promo codes you redeem and daily mission progress	To pay those bonuses once and stop abuse.
Which apps you use and for how long (usage access), only if you allow it	So playtime offers can credit coins for minutes played in partner games. Shared only with the playtime partner for offers you start.

We do not collect your contacts, photos, precise location or payment card details, and we never sell your personal information.

Offer partners

Offers in the Earn tab are run by our partners, including Tapjoy, adjoe and web offerwall providers named in the app. When you open a partner's offers, the partner receives your CoinKing user ID (a random code, not your name or number) so it can tell us when you earn coins. Partners also collect information on their own, such as your device's advertising ID, the apps you install from their offers and your progress in them, under their own privacy policies, which they show before you start.

Advertising

The mini-games show banner and full-screen ads, and you can choose to watch a short video ad to continue a game or save a check-in streak. Ads never give coins. Ads are served by Google AdMob and, through AdMob, by AppLovin, Unity Ads and Meta Audience Network. These networks may use your advertising ID, internet address and how you interact with ads to show and measure ads, under their own privacy policies. Google describes its use in How Google uses information from sites or apps that use its services. You can reset or delete your advertising ID in your phone's Settings > Privacy > Ads.

Service providers

Google Firebase (login, database, server functions, notifications, crash reports). Data is stored in Google Cloud's Sydney region.
Google Play Integrity (device checks).
Tremendous (sends PayPal payments and gift cards to your payout email) and PayPal.
Our bank (sends bank transfers to your PayID).

Some of these providers may process information outside Australia, including in the United States. We use providers that protect information under contracts and recognised security standards.

How long we keep it

We keep your account information while your account is open. When you delete your account we delete your name, payout email and notification settings straight away, and replace your phone number with a one-way code. We keep records of coins earned and payments made, without your contact details, for 5 years, because Australian tax law requires business records and because we need them to prevent fraud. Crash reports are kept for 90 days.

Your choices and rights

See your coins and cash-outs in the app's Wallet at any time.
Change your name, payout email and PayID in the app.
Turn notifications and usage access on or off at any time.
Delete your account in the app (Profile > Delete account) or on our account deletion page.
Ask us for a copy of the personal information we hold about you, or to correct it, by emailing support@sardarjidevelopers.com.

Age

CoinKing is for people aged 18 and over. We do not knowingly collect information from anyone under 18, and we close accounts we find belong to someone under 18.

Security

Information is encrypted in transit and stored with Google Cloud. Only the account holder and our admins can read an account, and every change to coins happens on our servers, not in the app.

Complaints and contact

Email support@sardarjidevelopers.com with any question or complaint about privacy. We will reply within 30 days. If you are not happy with our answer, you can contact the Office of the Australian Information Commissioner at oaic.gov.au.

Changes

If we change this policy we will update the date above, and tell you in the app if the change is significant.
