2. Information we obtain
| Information | When obtained | Purpose |
|---|---|---|
| Email address | At trial application or purchase | Sending the license key; communications about the Service |
| License status and expiration date | When a license is issued or renewed | License management |
| Device identifier (a random string) | When the add-in is first launched | Enforcing the limit of one PC per license. It does not include your name, IP address, hardware information or similar data |
| Payment-related information | When a paid plan is purchased | Payment processing and contract management. Payment information such as credit card numbers is obtained and processed directly by Stripe, Inc.; we do not obtain or hold it. However, for contract management we may view, through Stripe's dashboard, the email address, whether a payment succeeded, the plan purchased and the Stripe customer ID. If a Team plan is paid by invoice (bank transfer, available in Japan), the company name for the invoice is registered with Stripe (we do not store it in our license data), and Stripe confirms the transfer |
| Company name and team name | At Team plan application | Contract management; display in the admin console and in the notification emails sent to members |
| Members' email addresses | When a Team plan administrator assigns a license | Sending license keys to members; showing assignment status to the administrator. This information is provided by the subscriber (administrator), not by the members themselves |
| Your Excel environment (Windows, Mac or web, and its version; the KoreDefo version) | When the add-in checks the license | Responding to inquiries and bug reports; improving platform support. It does not include the contents of Target Files |
| Usage status (date and time of last check, whether registered to a PC) | When the add-in checks the license | Showing usage status to the Team plan administrator; license management |
| Admin console sign-in information (email address, sign-in date and time) | When a Team plan administrator signs in to the admin console | Identity verification for the admin console |
| Identifier generated from the IP address | When a trial application, contact or key resend form is submitted | Preventing abuse such as mass submissions in a short time. Stored only in a form that cannot be converted back to the original IP address (a hash value), and deleted after about one day |
| Where your visit came from (which site or ad, e.g. Google Search, X) | When you apply for a trial or a paid plan | Understanding which ads and posts work. It does not include anything that identifies you |
Information we do not obtain: the contents of Target Files, your name, phone number or address (except where you choose to provide them when contacting us).
About the Team plan: the check criteria published by the administrator (which check items are used, their severity, and the allowed fonts setting) are stored on our servers and delivered to each member's add-in. Even in this case, the contents of Target Files are never transmitted.
3. Purposes of use
- To issue, authenticate and renew license keys
- To contact you about the end of your trial and about payments
- To send important notices about the Service
- To respond to inquiries
- To allow the administrator, under the Team plan, to assign licenses, suspend their use and check usage status
- To investigate bugs and improve platform support
- To prevent abuse
4. Provision to third parties and outsourcing
We operate the Service using the following external services. We provide information to these providers only to the extent necessary for them to provide their respective services.
- Stripe, Inc. (payment processing)
- Resend (email delivery)
- Supabase (database hosting)
Other than the above, we do not provide personal information to third parties without your consent, except as required by law.
5. Retention period
We retain personal information for as long as necessary to achieve the purposes set out in "3. Purposes of use", and delete it without delay once it is no longer necessary. However, where retention is required by law, we retain it for the period set by that law.
6. Security measures
License keys are issued in a format that allows forgery or tampering to be detected by a cryptographic signature, and all communications are encrypted with TLS. Access to the database is restricted to the extent necessary for business purposes.
7. Requests for disclosure, correction, deletion, etc.
You may request disclosure, correction, suspension of use or deletion of the personal information about you that we hold. Contact us through the contact form. After verifying your identity, we will respond in accordance with applicable laws.
