Terms of Use
Last updated: 21 August 2026
These Terms of Use apply to the Yuika mobile app and website. By using Yuika you agree to them.
1. Apple standard EULA
Yuika is distributed on the Apple App Store under Apple’s standard Licensed Application End User License Agreement. That agreement is incorporated here by reference:
https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
If anything in this page conflicts with Apple’s standard EULA for an App Store download, Apple’s EULA controls for that download.
2. The service
Yuika helps you understand Japanese administrative documents. Outputs are guidance only — not legal, tax or immigration advice. Always verify amounts, deadlines and instructions against the original document and official sources.
3. Yuika Premium (auto-renewing subscription)
Free accounts include a monthly scan allowance. Yuika Premium is an auto-renewing in-app subscription that unlocks unlimited document scans.
- Yuika Premium Monthly — length: 1 month.
- Yuika Premium Yearly — length: 1 year.
Price is shown in the app in your local currency before you confirm the purchase (charged to your Apple ID or Google Play account). Payment is charged at confirmation of purchase. The subscription renews automatically unless you cancel at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours prior to the end of the current period. After purchase you can manage or cancel in your store account settings (iOS: Settings → Apple ID → Subscriptions; Android: Google Play → Payments & subscriptions).
Any unused portion of a free trial, if offered, is forfeited when you purchase a subscription.
4. Privacy
How we handle your data is described in our Privacy policy.
