Yellz Monthly Ranking Reward Official Rules (English)

The Japanese version of these Rules is authoritative; this English version is a reference translation.

1. Scope of these Rules

1. These Rules set out the conditions of the reward that gives Premium features to top contributors in the monthly contributor rankings of the Service (the “Reward”).
2. The Service's Terms of Service, Privacy Policy and Community Guidelines also apply. If they differ from these Rules regarding the Reward, these Rules prevail.
3. We are the sole sponsor of the Reward.

2. Apple and Google

Yellz is the organizer of this Reward. Apple is not involved and is not a sponsor.

The Reward is sponsored and administered solely by us. Apple Inc. and Google LLC (including their affiliates) are not sponsors of the Reward and are not involved in any manner in sponsoring, administering or judging it. Please direct any questions about the Reward to us, not to Apple or Google.

3. Periods

1. The Reward applies to each monthly ranking period. A monthly period is a calendar month in Coordinated Universal Time (UTC), from 00:00 UTC on the 1st of the month until immediately before 00:00 UTC on the 1st of the next month. In Japan and Korea this is from 9:00 on the 1st until immediately before 9:00 on the 1st of the next month.
2. The Reward starts with the monthly ranking for November 2026 (UTC) and continues until we announce its end.
3. Weekly rankings, all-time rankings and per-artist rankings are not eligible for the Reward.

4. Territory and eligibility

You are a participant if you meet all of the following:

1. You live in a country or region where the Service is distributed (the Service is not distributed in the European Union (EU), the European Economic Area (EEA), the United Kingdom or Switzerland). Residents of countries or regions where the Reward is prohibited or restricted by law are not eligible. You declare your country of residence when you receive the Reward.
2. You meet the eligibility requirements of the Terms of Service (age 13 or older outside Korea; age 14 or older in Korea). Only adults aged 18 or older may receive the Reward, subject to the applicable country’s age-of-majority determination. Minors remain displayed in rankings but are not eligible for the Reward. Users whose age category is unset or unknown are also ineligible. Adult status is checked when candidates are created and before approval and grant.
3. You have a Service account that is not suspended.
4. Your contributor profile is set to “Public” and has a nickname. If your profile is private or has no nickname, you will not appear in rankings and are not eligible for the Reward.
5. You are not one of our officers, employees or contractors, or a member of their household (they may appear in rankings but are not eligible for the Reward).

5. No purchase necessary

1. No purchase, payment or entry is necessary to participate in or receive the Reward. Having or not having a Premium subscription does not affect points, rank or winning.
2. Purchases in the Service (including in-app purchases and web purchases) cannot be used to gain or improve eligibility, points, rank or the chance of winning.
3. There is no separate entry procedure. Anyone who meets the conditions in Section 4 is considered based on their monthly ranking position. If you do not wish to participate, set your contributor profile to “Private”.

6. How ranks are determined

6.1 Points

Contribution points are awarded when a contribution to the shared database is confirmed or accepted. The current values are below (we may change them and will give notice in advance).

• Points are never awarded twice for the same event.
• Points may not be awarded for “Thanks” or correction reports between accounts that we determine are not independent of each other, such as accounts linked to the same payment method.

6.2 Calculation

1. Your score for a period is the sum of point changes that occurred within that period (UTC) — that is, at the time of confirmation, acceptance, reversion and so on. It is based on when a contribution was confirmed or accepted, not when it was submitted. Negative points from reversions are included.
2. Participants with a total of zero or less are not ranked.
3. The ranking scopes eligible for the Reward are:

- Global: all contributions combined. - By country: totals per country of the venue of the performance the contribution relates to. This is not the participant's country of residence or nationality. Contributions not linked to a performance are not counted by country.

1. Ranks are in descending order of score. Participants with equal scores share the same rank, and the next rank skips accordingly (for example, 1st, 2nd, 2nd, 4th).
2. Ranks are assigned among accounts that are not suspended, have a public contributor profile and a nickname, and are not excluded by the fraud review (Section 8). Ranks close up after private profiles, accounts without a nickname, suspended accounts and fraud-review exclusions are removed. Age does not exclude users from rankings or change their points or ranks. Each ranking shows the top 100.

6.3 Finalization

1. A monthly ranking is finalized by our daily aggregation once two days have passed after the end of the period and no fraud review involving its candidates is still open. If a review continues, finalization is delayed.
2. A finalized ranking is not recalculated. Point changes after finalization do not change the finalized ranks or Reward eligibility. However, we may revoke the Reward under Section 8.

7. Reward and number of winners

1. Eligible: adults ranked 10th or higher in a finalized monthly ranking (global or by country) who meet the Reward eligibility conditions in Section 4. Because of ties, more than ten participants may qualify in a single ranking. Excluding minors or users whose age category is unset or unknown from the Reward does not promote adults from outside the eligible ranks.
2. Reward: “Yellz Premium, 1 month (30 days)” free of charge (approximate retail value JPY 480, the monthly price in Japan).
3. Number: even if you place in more than one scope in the same month (for example, global and a country), you receive one Reward per month. The number of winners each month In principle there are 10 winners per scope, which may increase because of ties. The total each month depends on the number of country rankings that are eligible. There is no cap.
4. Delivery: we deliver the Reward by one of the following, depending on how you subscribe to Premium. The Reward cannot be exchanged for cash or other goods, transferred, resold or refunded.

- Subscribed through the App Store: an App Store offer code - Subscribed through Google Play: a Google Play promo code - Subscribed on the web (Stripe) or not subscribed: a web purchase coupon (100% off for one month, single use)

1. Terms of use for each code (expiry, eligible regions, effect on an existing subscription, etc.) follow the conditions of each store or payment provider. If a code cannot be used because its conditions do not fit, contact support@yellz.app within the receiving deadline and we will provide the Reward another way.

8. Prohibited conduct and disqualification

1. The following are prohibited. If we determine that you have engaged in them, we may remove you from rankings, decline to grant the Reward, or revoke a granted Reward and related points and badges.

- Creating or using multiple accounts; lending, transferring or selling an account - Collusion with others, trading rewards, or using bots or automation for proposals, support, reviews or “Thanks” - Posting false performance information or setlists, or any other violation of the Community Guidelines

1. We detect suspected multiple accounts through overlapping signals such as the same payment method, and a person reviews them before a ranking is finalized. Depending on the result, all or some of the related accounts are excluded. Sharing a household or device alone does not lead to immediate disqualification; we consider other circumstances as well.
2. Participants whose accounts are suspended or deleted before notification or delivery are not eligible for the Reward. The same applies if an account is deleted or suspended after finalization but before delivery; the Reward is not granted retroactively even if a suspension is later lifted.
3. We review each Reward candidate individually before granting. We may decline to grant the Reward if we determine that a candidate has violated these Rules for the reasons above or otherwise.

9. Winner notification and delivery

1. After finalization and our review, we notify each winner privately by an in-app notice and deliver the code. We do not publish winners' names or contact details (rankings show the nickname and other public profile data).
2. The deadline to receive or use the Reward is 30 days after notification. If the code is not received or used by the deadline, the Reward expires and is not reissued.
3. We do not ask for additional personal information such as your name, address or phone number to deliver the Reward. Adult status is checked with your stored age category; we do not collect dates of birth.
4. Any data or communication charges needed to use the code are your responsibility.

When receiving the Reward, the winner selects and declares their country of residence. A country outside distribution is treated as declining the Reward. No new email address is collected. The declared country is used only to process the Reward.

10. Personal information

1. To administer the Reward we use the following information already collected by the Service:

- Account identifier, contribution points and their history, and ranking positions - Public profile nickname, public ID and level (shown in rankings) - Overlapping signals for fraud review (such as the same payment method; review records do not store the payment method value itself) - Stored age category to check Reward eligibility (not published in rankings) - Subscription channel (App Store / Google Play / web) to choose the delivery method

1. Records of Reward candidates, reviews and grants are accessible only to administrators, and administrative actions are logged in audit records. The retention period is 3 years from the grant (or from the decision, if not granted).
2. Otherwise, our Privacy Policy applies.

11. Changes and cancellation

If there is widespread fraud, a system failure, a change in law or other unavoidable circumstances, we may change these Rules or the Reward, or suspend or cancel the Reward. We will announce changes that are disadvantageous to participants in the app or by other reasonable means before they take effect. Winners of monthly rankings finalized before the announcement will, as a rule, receive the Reward under the previous conditions.

12. Liability and governing law

Limitations of liability, governing law and jurisdiction for the Reward follow the Terms of Service.

13. Contact
