Ondoku annual contracts are not automatically renewed.
If you wish to renew your contract, you must complete the renewal procedure yourself.
In this article, we will introduce the "renewal method" for annual contracts and "what happens if you do not renew."

* If your desired start date is after the payment date, please notify us by email at least 3 business days in advance. We cannot accommodate requests if the notification and payment are out of sequence.
(Example) Payment on March 20 → Desired start date: April 1
Please notify us by email 3 business days before March 20.
We cannot accommodate requests even if notified on the day of March 20.

The username will be the addressee on the invoice.
If you have registered an incorrect username:
You can change the username this way.
A quotation is issued at the same time as the invoice, so it is very easy to download even if you need a quotation for internal approval.
Invoices can be created easily with a single button.
Because of this, you may accidentally create unnecessary invoices.
Deleting or canceling invoices cannot be done by the customer.
If you have accidentally created multiple invoices, please contact us via the inquiry form to request deletion.
Quotations and invoices without payment or contact for more than 3 months will be deleted as expired.
If payment is received while multiple invoices exist and no invoice number is specified, the plan for the invoice with the most recent date will be activated.
The designated bank for transfers is SBI Shinsei Net Bank.
Other accounts are currently being prepared.
Since there is a branch name and account number, you can make transfers from other banks. Of course, transfers between SBI Shinsei Net Bank accounts are also easy.
Accounts other than SBI Shinsei Net Bank are currently being prepared. Thank you for your understanding.
In principle, the plan is activated within 24 hours after confirming the transfer.
If the username and the name of the remitter are different, we cannot confirm the payment. Please be sure to notify us via the inquiry form.
* If you are in a hurry, we can accommodate plan activation if you inform us of the approximate payment date even before the funds arrive.
In that case, please contact us via the inquiry form after issuing the invoice.
Furthermore, if payment cannot be confirmed even after 7 days have passed since the notified payment date, the account plan will be suspended.
Status represents the payment situation after the invoice has been issued.
Once the status becomes Paid, you can download the receipt.

After the plan is activated, you can download the receipt from the Invoice Issuance History.
If you do not renew your annual contract, what happens to your Ondoku account and the audio you created?
Once the expiration date passes, it will automatically revert to a Free Plan (5,000 characters/month).
When you transition to a Free Plan, history and data will be automatically deleted after 30 days.
Once deleted, the data is also removed from the server. Please note that once data is deleted, it cannot be restored.
If you wish to delete data immediately, please use the deletion function or bulk deletion function.
With the newly introduced "Deletion" function, you can now easily delete your previous spoken data yourself! We will introduce how to use the Deletion function and Bulk Deletion function, as well as points to note.
It is a **prohibited act** to use audio created while using a paid account after transitioning to a free account without credit notation.
If you continue to use it, credit notation is mandatory. If you cannot provide credit notation, please stop using it.
If it was a Business Plan, this is an exempt item, and audio created during your contract can continue to be used.
