All PDF processing in the App (including imposition processing) is completed locally on the user’s device.

3.1 Regarding Purchase Processing by App Stores

Purchase processing for the App is handled through each app store operated by Apple Inc. and Google LLC. Information that users have registered with each store (Apple ID, Google account, payment information, etc.) is handled by the respective operator. This information is not disclosed to us.

We receive receipts or tokens indicating the fact of purchase from each store, but these are used only for verification purposes within the App (on the user’s device) and are not transmitted to our servers.

For information about personal information handling at each store, please see:

3.2 Voluntary Provision via Contact Form

The App provides a contact form. If a user voluntarily contacts us through this form, the content of the inquiry and the return contact information (email address, etc.) are sent from the user’s device directly to our email address.

We use this information solely for responding to the inquiry, and delete it within two years after the response is complete.

4. Purpose of Use

Information voluntarily provided by users under Section 3.2 is used only for the following purposes:

Responding to and addressing inquiries
Improving the App (when aggregated in a non-identifying manner)

We do not use personal information for any other purposes.

5. Provision to Third Parties

We do not provide collected personal information to third parties except in the following cases:

When we have obtained the user’s consent
When required by law
When necessary to protect a person’s life, body, or property, and obtaining the user’s consent is difficult

6. Security Measures

We have implemented the following measures to prevent leakage, loss, or damage of information provided through the contact form:

Encryption of communication channels (HTTPS / TLS)
Minimization of access rights to received inquiry information
Deletion within a reasonable period after the inquiry has been addressed

Users may request the following with respect to personal information they have provided to us through the contact form, based on Japan’s Act on the Protection of Personal Information:

Notification of purpose of use
Disclosure
Correction, addition, or deletion
Cessation of use or erasure

To make such requests, please contact us at the contact information listed at the end of this Policy. After identity verification, we will respond within a reasonable period in accordance with applicable law.

8. Children’s Privacy

Although the App is not specifically targeted at any particular age group, we do not knowingly collect personal information from children under 13 (or under 16 for residents of the European Economic Area and the United Kingdom). As described in the preceding section, the App is designed not to actively collect personal information in the first place.

Users residing in the European Economic Area (EEA) and the United Kingdom have various rights under the GDPR and UK GDPR regarding personal data (access, rectification, erasure, restriction of processing, data portability, objection, and the right to lodge a complaint with a supervisory authority).

We do not actively collect personal data from users in connection with the use of the App. Only information voluntarily provided through the contact form constitutes personal data we hold. To exercise rights regarding such data, please contact us at the contact information at the end of this Policy.

10. For California Residents (CCPA / CPRA)

Residents of California have various rights under the California Consumer Privacy Act (CCPA) and California Privacy Rights Act (CPRA) regarding personal information.

We do not sell or share any personal information with third parties.

Since we do not actively collect personal information from users in connection with the use of the App, the data subject to disclosure requests is limited to information voluntarily provided through the contact form.

11. Cookies and Similar Technologies

The App does not use cookies or similar tracking technologies.
