Article 1. Purpose

These terms set out the conditions for using Postmark Lane (the “Service”), a block placement puzzle game provided by Goyo (“we”), and the rights and duties of Goyo and of you as a user.

Article 2. Definitions

  1. “Service” means the app Postmark Lane as distributed on Google Play and App Store and Apps-in-Toss.
  2. “User” means a person who uses the Service under these terms.

Article 3. Applying and changing these terms

  1. These terms apply once we post them on the Service's policy screen or a public web page.
  2. We may change these terms so long as the change does not break applicable law.
  3. When we change them we give the effective date and the reason from 7 days before that date, and from 30 days before for an important change that is unfavourable to you.
  4. If you do not agree with a change you can stop using the Service. If you keep using it after the notice period, we treat that as agreement.

Article 4. Eligibility

  1. Game progress stays on your device. Only Apps-in-Toss sends an HMAC of your anonymous Toss key, daily completed-run counts, reward balance, ledger and payout keys to our AWS server in Seoul. We do not collect names or contact details.
  2. We may refuse or restrict use if you use someone else's information, have previously been restricted for breaking these terms, or try to obtain records in the Service by illegitimate means.

Article 5. What the Service provides

  1. We provide an endless block puzzle where you place three pieces on an 8×8 map and complete rows or columns.
  2. We may change the rules, difficulty, rewards, screens, and features to keep the Service stable and to improve it. We give notice of important changes in advance.

Article 6. Using the platforms

  1. You must also follow the terms of Google Play or App Store or Apps-in-Toss, wherever you downloaded or run the Service. Distribution, updates, and payment are governed by that platform's policies.
  2. A platform outage, policy change, or end of support may temporarily limit your use of the Service.

Article 7. Toss promotion

  1. Games are unlimited. On Apps-in-Toss and in earlier free editions, the Unlimited Pass removes ads and allows one ad-free continuation per game. The paid Google Play and App Store editions have no ads or in-app purchases.
  2. Only in Toss, the 1st, 5th and 15th final game completed each Korean calendar day award 10, 20 and 30 delivery stamps (60 per day). Abandoned and practice games are excluded; continuation is the same game.
  3. Exchange 1,000 stamps for KRW 100 in Toss Points, up to KRW 500 per day. Exchanges end when the budget is exhausted or at 2026-12-31 23:59:59 KST. Uncertain payouts remain pending and are never paid twice. Stamps cannot be purchased or transferred.

Article 8. In-app purchases and refunds

  1. The paid Google Play and App Store editions are bought from the store and include no in-app purchases. Purchase and refunds of the app follow the policies of the store where you bought it.
  2. On Apps-in-Toss and in earlier free editions, the Unlimited Pass is bought with that platform's in-app payment and restored with the same platform account. It removes ads and allows one ad-free continuation per game.
  3. Refunds follow applicable law and the payment policies of the platform where you paid.
