Article 4 (Fees and Payment)

Free trial: For 7 days from registration, you may use the Light plan (50 uses per cycle) free of charge. The free trial applies to the Light plan only. The Standard and Max plans are not eligible for the free trial and are charged from the time you sign up (you may upgrade during or after the trial)
Starting the trial: A credit card is required to start the trial. If you cancel during the trial period (within 7 days), no charge is made. If you do not cancel, the Light plan fee is charged automatically after the 7 days and renews monthly on the same date. You can cancel at any time from the settings screen in the app
One trial per person: The free trial is limited to one per person (one account). If you sign up with an email address or credit card that has already used a free trial, the trial does not apply and the regular fee is charged from the time you sign up
Deleting your account is different from cancelling. If you delete your account, your subscription is cancelled immediately, and you cannot use the Service for the rest of the paid period, nor is that remaining period refunded (any remaining add-on uses are likewise forfeited). If you wish to use the Service until the end of the current cycle, please use "Cancel" instead of deleting your account
Light plan: ¥480 per month (tax included), OCR 50 uses per 30-day cycle
Standard plan: ¥880 per month (tax included), OCR 100 uses per 30-day cycle
Max plan: ¥1,280 per month (tax included), OCR 200 uses per 30-day cycle
Add-on pack: ¥330 (tax included), OCR +50 uses (one-time purchase; no expiry date, valid until used up and carried over across cycles). Add-on packs can be purchased and used only while you have an active plan. If your plan ends following cancellation, or if you delete your account, any remaining uses are forfeited and cannot be refunded (except in the cases described below)
The 30-day cycle begins on the date of subscription (or on the date the trial starts), and the plan's base usage count is reset every 30 days (any remaining add-on uses are not reset and carry over)
Payments are processed via Stripe. Credit cards, debit cards and similar payment methods may be used
Subscriptions renew automatically. You may cancel at any time, and even after cancellation you may continue to use the paid features until the end of the current cycle
Deletion of Data After a Long Period Without a Subscription: While you are on a paid plan, your data is never deleted, regardless of how often you use the service. Only accounts that remain for 90 consecutive days without a paid plan and without a free trial will have their data deleted automatically. Before deletion we will notify you four times by email (when the account becomes subject to deletion, and 30 days, 7 days, and 1 day before). If you resume use during this period, the scheduled deletion will be cancelled. Events, tasks, and scan results shared with a group are not deleted; only the author's name is replaced with "A member who left". Please see the Privacy Policy for details
If payment cannot be confirmed: If payment (credit card payment) cannot be confirmed, we will provide a grace period of approximately 7 days. If your card information is not updated during this period, use of the paid features will be temporarily suspended. Your data will not be deleted, and once payment resumes you may continue to use the Service with the same account
As a general rule, fees already paid (including unused add-on uses) are not refunded. However, this does not apply where you were unable to use the Service for reasons attributable to us (such as a serious malfunction of the Service), where there is an obvious payment error such as a duplicate charge, or where a refund is otherwise required by law. Please contact us for refund inquiries
Fees may be changed without prior notice. In the event of a change, we will give notice in advance within the Service
