BUKU 3 is a simple loyalty app that helps users stay active, make eligible purchases, redeem receipt codes, collect entries, and follow their progress toward monthly and annual rewards in a clear and trusted way.

Users can create an account with their phone number, verify access using an OTP code, and complete their profile. After registration, the platform may award a Welcome Entry, which appears in the user’s entry history with the source shown as Welcome Entry.

Users can also invite friends using a referral code. When a valid referral is completed, entries may be awarded to both users, and the source is shown as Referral Free Entry.

Receipt redemption is one of the main ways users collect entries. After making an eligible purchase, users can enter the receipt code manually. On mobile, users can also scan a receipt so the code can be detected more easily before submission. When a valid receipt code is accepted, entries are added with the source shown as Purchase.

The platform may also provide Weekly Free Entries so users can continue participating in monthly and annual reward activities. BUKU 3 also includes streak tiers, where users complete tier activities step by step. Streak tiers do not have a fixed time limit. When one tier is completed, the next tier unlocks, and entries are awarded based on that tier with the source shown as Streak Entries.

Users can view their entry history, active rewards, reward information, notifications, referral activity, streak progress, and public reward recipient updates. This helps users clearly understand how their entries were collected and how their loyalty activity is progressing.

BUKU 3 gives users a simple loyalty journey: make eligible purchases, redeem receipts, collect entries, complete streak tiers, and stay updated on monthly and annual rewards. Users with more valid entries may have stronger participation in reward activities, based on the official platform rules, eligibility checks, and verification process.

The app is designed to keep loyalty participation simple, transparent, and easy to follow.
