YohakuArticle 1 — Application
These Terms govern the iOS app “Yohaku” and the official brand website (together, the “Service”) provided by Tomokichi (the “Operator”). By downloading the App or using the Service, you agree to these Terms.
Article 2 — The Service
Yohaku lets you leave time with nothing planned by giving it a name and times, then review those spaces on Today, Week and Month. Core features are free and no account is required.
Article 3 — Advertising
The App carries advertising from its first release. In the free version, an anchored banner ad appears on screens such as Today, Week and Month. Ads are intended to stay unobtrusive, but complete non-interference is not guaranteed. Advertising uses an external provider (Google Mobile Ads), and the Operator does not individually select which ads appear or in what order. Ads do not appear after the “Remove ads permanently” purchase described in Article 4.
Article 4 — In-app purchase
The App offers one non-consumable, one-time product: “Remove ads permanently” (¥400, tax included). Buying it permanently stops ads as a thank-you for supporting development. It does not unlock extra core features, and it is neither a subscription nor a product that expires.
On the same Apple Account, the purchase can be restored from Settings. Purchases, restores and refunds follow Apple’s terms, and Apple decides whether a refund is granted. The tax-inclusive price shown on the App Store product page and the in-app purchase screen is authoritative.
Article 5 — License
Subject to these Terms, the Operator grants a personal, non-exclusive, non-transferable right to use the App.
Article 6 — Prohibited conduct
You must not:
1. Violate law or public order
2. Gain unauthorized access, disrupt operations, or abuse system vulnerabilities
3. Evade payment or forge purchase entitlements
4. Manipulate ads fraudulently (including invalid clicks)
5. Unlawfully copy or redistribute the App
6. Reverse-engineer where not permitted by law
7. Abuse the support form or harass others
8. Engage in any other conduct the Operator reasonably finds inappropriate
Article 7 — Data
Space records are stored on your device. There is no Yohaku cloud sync, device-to-device sync, export or import. You manage your own device. Records may be lost if you delete the App, lose or damage the device, or face OS issues; the Operator cannot restore lost spaces.
Article 8 — Notifications
Notifications are an aid only and delivery is not guaranteed. Do not rely on them as a critical planner or alarm. OS settings, device state, power saving and permission may prevent delivery.
Article 9 — Medical disclaimer
The App is not a medical device and does not guarantee medical, psychological or health outcomes. Seek qualified help if you have health concerns.
Article 10 — Disclaimer
The Service is provided “as is.” The Operator does not warrant completeness, accuracy, continuity, uptime or freedom from defects, except where mandatory law such as the Consumer Contract Act limits this disclaimer.
Article 11 — Limitation of liability
Except for willful misconduct or gross negligence, and to the extent permitted by law, the Operator is not liable for damages from use or inability to use the Service. Where mandatory law disallows full exclusion, liability is limited to what the law allows.
Article 12 — Changes, suspension, termination
The Operator may change, suspend or end the Service for OS support, law, ads, purchases, maintenance, security or similar reasons.
Article 13 — Changes to these Terms
These Terms may be revised. Revised Terms take effect when posted in the App or on the official website.
Article 14 — Governing law and jurisdiction
These Terms are governed by Japanese law. Unless mandatory consumer law provides otherwise, the Tokyo District Court has exclusive first-instance jurisdiction.
Article 15 — Contact
Questions: in-app support, the shared support form, or support@tmkch.io.
