Privacy Policy

Effective date:

This policy explains what information (“the app”), published by (“we”, “us”), collects, how it is used and the choices you have. Contact us any time at .

1. Information we collect

Account information (you give us)

• Email address: to create and secure your account and send confirmation and password-reset emails.
• Password: stored only as a secure hash by our authentication provider; we never see it.
• Username: shown inside the app and on the public leaderboard.
• Invite code you enter (optional): links your account to the friend who invited you.

Payout information (you give us when you withdraw)

• Lightning Address or FaucetPay account email: used only to send the BTC you withdraw, and kept with the withdrawal record for accounting and fraud checks.

App activity (created when you use the app)

• Your BTC balance, mining sessions and mining days, boosts, game results, completed tasks, check-in streak, invited friends and withdrawal history.
• A record of each action that showed an ad (date, time and purpose), used for daily limits and fraud prevention.

Advertising data (collected by Google AdMob)

The app shows ads from Google AdMob. Google may collect your device’s Advertising ID, IP address, approximate location derived from it, device and app information, and ad interactions, to show and measure ads and to prevent fraud. In the EEA, UK and Switzerland we ask for your consent through Google’s consent form before ads are personalised. See how Google uses information from apps that use its services.

Notifications

If you allow notifications, the app schedules a reminder on your phone when a mining session ends. This happens on your device; no notification data is sent to us.

We do not collect your contacts, photos, precise location, phone number, bank or card details, or any crypto wallet private keys.

2. How we use information

• To run the app: keep you signed in, save progress, calculate mining rewards and pay withdrawals.
• To show the public leaderboard (username, total mined and rank only, never your email).
• To prevent cheating, multiple accounts, fake invites and other abuse, including manual review of withdrawals.
• To show ads that fund the rewards.
• To answer support requests.

Legal bases (EEA/UK): performance of our contract with you (running your account and paying withdrawals), legitimate interests (security and fraud prevention) and consent (personalised ads).

3. Sharing

We do not sell your personal information. We share it only with service providers that run the app for us:

• Supabase: hosts our database and handles sign-in (data encrypted in transit).
• Google AdMob: serves and measures ads, as described above.
• Your payout provider: when you withdraw, the Lightning Address or FaucetPay email you entered is used to send the payment through that network or service.

We may disclose information if the law requires it.

4. Bitcoin rewards

The app pays small amounts of BTC funded by advertising. It does not mine cryptocurrency on your device and does not use your phone’s processor or battery to mine. See the Official rules.

5. Keeping and deleting your data

We keep your data while your account exists. Withdrawal records may be kept for up to 5 years where accounting or anti-fraud laws require it. You can delete your account at any time:

• In the app: Profile → Delete account, or
• On the web: delete your account here, or
• By emailing from your account email.

Deletion is immediate in our live database. Copies may remain in encrypted backups for up to 30 days. Any unwithdrawn BTC balance is lost when the account is deleted. Data held by Google AdMob is governed by Google’s own retention policies.

6. Security

All traffic between the app and our servers is encrypted (HTTPS). Database access is restricted so each user can only read their own data, and every balance change happens on the server.

7. Children

The app is for adults aged 18 and over and is not directed to children. If you believe a child has created an account, contact us and we will delete it.

8. Your rights

Depending on where you live (including under the GDPR, UK GDPR and US state laws such as the CCPA), you may have the right to access, correct, export or delete your data, or to object to certain processing. Email and we will respond within 30 days. You can change your ad consent any time in Profile → Ad privacy choices. You may also complain to your local data protection authority.

9. Changes

If we change this policy we will update the date above and, for important changes, tell you in the app.
