FAQ

Yumo Yumo is a personal financial operating system built around Proof of Expense. It turns receipts, routines, and price memory into actionable guidance and contribution history.

Upload or scan an eligible receipt. Our system extracts totals, line items, merchant context, and hidden-cost signals using AI and OCR. Validated contributions may generate bINT — the in-app reward accounting unit — subject to published caps, eligibility rules, and trust checks.

Proof of Expense (PoE) is Yumo Yumo's core mechanism: every reward and insight is backed by a real-world spending event. A verified receipt becomes proof — not speculation, not engagement farming. It anchors the entire reward system to actual economic activity.

Hidden costs are the price components not directly visible to shoppers — brand premiums, retail margins, import costs, and the inflation wedge. Yumo Yumo estimates these from real public data (e.g. TÜİK/CPI) and receipt signals to create a transparency metric, not a financial projection.

By contributing eligible receipts and participating in product-defined contribution events. Each validated receipt is scored by quality, trust, and hidden-cost signals. The resulting bINT record follows deterministic rules, daily caps, anti-duplicate gates, and level-based limits.

bINT is Yumo Yumo's in-app reward accounting unit — it's what you earn and see inside the app. INT is the token on Solana. bINT settles to INT at 1:1 when claim rails are open, subject to eligibility, wallet checks, jurisdiction, and legal review.

INT can be claimed to your wallet, staked for long-term incentives, or used within the ecosystem as rails open. Transfers, staking, and program participation follow published terms, eligibility gates, and sanctions screening.

No. Yumo Yumo provides spending awareness and receipt-grounded contribution records. Nothing in the app is investment advice, a price prediction, or a promise of future value.

Receipt data is treated as sensitive. Receipt images may be stored briefly for processing and integrity checks, then targeted for deletion. Structured records are kept only as needed for product, compliance, and abuse-prevention. We never expose personal payment details.

The reward system uses deterministic rules, daily caps, anti-duplicate gates, trust scoring, and level-based limits. There is no secret minting — every bINT record is traceable to a verified contribution event.

The platform is open. Some features, reward eligibility, and token claims may require account verification, wallet checks, and jurisdiction review depending on your region.
