Rollin Terms of Service
Effective date: October 29, 2026
1. Operator and acceptance
Rollin is operated by 難波隼士 (Hayato Namba). It lets groups share goals and record challenges, offers and achievements. Please agree to these Terms before use. Minors must obtain a parent or guardian's consent. Keep registration details accurate, protect your credentials and contact us if you learn of unauthorized use.
2. Content and safety
You retain rights to your display name, group, goal, challenge, offer and other content. You must have the necessary rights and grant the operator a non-exclusive license limited to providing, displaying, maintaining and safeguarding the service. Content is shared with other users according to participation and viewing permissions. Do not post sensitive information or other people's personal information.
Infringement, illegal or obscene content, threats, harassment, discrimination, impersonation, unauthorized disclosure of personal information, unauthorized access, service disruption and abuse of rewards, free allowances or purchase entitlements are prohibited. You can report and block users in the app and unblock them in Settings. We review reports and inquiries and may remove content, restrict use or suspend accounts according to the violation. Continuous monitoring or immediate action is not guaranteed. Email us to appeal an action.
3. Free use and premium
Free accounts may own up to three groups. Joining another person's group does not count. Creating a fourth or later group requires premium. Premium includes additional features displayed in the app, such as viewing a partner's avatar. Existing groups are not automatically deleted when access expires, but further creation and other premium actions may be restricted. Previously granted benefits follow your account entitlements. No new lifetime benefit is promised. Apple displays the conditions of official offer codes.
4. Auto-renewing subscriptions, cancellation and restoration
Premium is a monthly auto-renewing subscription. Check the app and Apple App Store purchase confirmation for the price, currency, included features and subscription period. Payment is charged to your Apple ID. The subscription renews automatically unless cancelled at least 24 hours before the current period ends. Renewal is charged within 24 hours before the period ends.
Manage or cancel on your iPhone through Settings → your name (Apple ID) → Subscriptions → Rollin. After ordinary cancellation, access continues until the paid period ends. Refunds follow Apple's procedures and terms. To restore, use the same Apple ID used for purchase and select Rollin Settings → Plan & benefits → Restore purchases. Entitlements are confirmed by the server. Deleting the app or your account does not cancel your subscription.
Apple's Standard End User License Agreement (EULA) also applies: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
5. Account deletion, service changes and liability
Delete your account in Settings → Account → Delete account and complete the confirmation steps. See the Privacy Policy for associated data deletion and retention exceptions. Recovery of deleted accounts or rewards is not guaranteed.
Avatars and rewards are supplementary features with no guaranteed cash value, financial benefit or goal achievement. We take reasonable security measures but do not guarantee uninterrupted operation, completeness or fitness for a particular purpose. Maintenance, failures or safety needs may require changes, interruption or termination. Where possible, we announce significant changes or termination in advance in the app or on the public site. Liability is determined by applicable law; nothing excludes liability for intent or gross negligence or liability that consumer protection or other law does not allow us to exclude.
6. Privacy, amendments and governing law
Personal information is handled under the Privacy Policy. We announce changes to these Terms and their effective date in the app or on the public site and obtain consent where required by law. Japanese law governs these Terms. Disputes are subject to the Japanese courts with jurisdiction under applicable law, without limiting mandatory consumer protections.
