Privacy Policy

Kami Grid
GalleryG, LLC
Last updated: September 1, 2026

This Privacy Policy explains how we handle information when you use the Kami Grid app (the “App”). We offer the App for iPhone, iPad, and Android phones and tablets.

This Policy applies to use of the App and to inquiries about the App. The App does not create accounts.

We are responsible for the handling of user information in the App.

2. What the App does not do

The App does not include the following. It also has no mechanism that sends your name, email address, or photos from the App screens to us.

  • Analytics
  • Advertising or collection of advertising identifiers
  • Crash reporting
  • Cross-app tracking
  • Account registration, sign-in, or cloud sync

Photos, capture settings, and in-app preferences stay on your device. The App cannot upload photos to our servers. We have no way to view the content of your photos.

3. Information handled on the device

3.1 Photos

The App captures photos with the camera, imports images, overlays a frame, and exports. All of this processing stays on the device.

Original images are stored in the App’s private storage on the device. Frames are not burned into the saved original; they are drawn at display time. Thumbnails and capture settings (paper size, grid, tone, and similar) are also stored only on the device.

If you export, the App composites the frame and tone and sends that image to the destination you choose (Photos, another app, or a share target). What happens next is governed by that destination.

3.2 App settings

Settings you choose, such as grid, paper orientation, and paper size, are stored on the device and restored the next time you use the App.

3.3 Device features (permissions)

The camera is used to take photos.
The photo library (or the system image picker) is used when you pick images to import and when you choose a destination for export.

The operating system asks for each permission when the related feature is used. If you deny it, that feature will not work. You can later revoke access in system settings. Paid features do not require you to grant these permissions.

4. Subscriptions and payments

The App offers one auto-renewing subscription.

Charging, payment, renewal, and cancellation are handled by Apple on iPhone and iPad, and by Google on Android. We do not receive card numbers or other payment instruments.

To determine whether a subscription is active, we use RevenueCat, Inc. (United States). We do not assign you our own account ID. RevenueCat uses an anonymous identifier created on the device. In that process, RevenueCat may process:

  • an anonymous identifier created on the device
  • device type, operating system, and app version
  • locale and currency information
  • IP address as part of network communication
  • purchase records (receipts or purchase tokens, product identifiers, subscription period)

Photos, names, and email addresses are not included. We do not collect advertising identifiers (such as IDFA or Google advertising ID).

Cancel the subscription in the account settings of the store where you purchased it. Deleting the App does not end the subscription.

5. Off-device transmission, processors, and transfers abroad

The only user information the App sends off the device is the information needed for the subscription check in Section 4. The only information-collection module we embed is the RevenueCat SDK. We do not embed analytics, advertising, or crash-reporting modules.

We entrust processing of that information to RevenueCat, to the extent needed to determine subscription status. Apple and Google handle purchase information under their own terms for store billing and subscription management.

RevenueCat is a U.S. company and processes data in the United States, including on cloud infrastructure it uses. This may constitute a transfer of personal data to a third party in a foreign country under Japan’s Act on the Protection of Personal Information. We require, by contract, purpose limitation, security measures, and limits on onward transfer. We require third parties that process data on our behalf to provide protection consistent with this Policy and applicable law.

In outline, the United States has no single federal privacy statute equivalent to Japan’s Act. Protection is provided through sector-specific rules and state laws (including the California Consumer Privacy Act). The EU has not issued an adequacy decision for the United States as a whole. Government authorities may, under defined conditions, compel disclosure. For more detail, see the Personal Information Protection Commission of Japan’s reference on the U.S. system.

RevenueCat’s measures include encryption in transit (TLS) and access control. Its practices are described in its own policy.

We may disclose information where required by law, to protect rights, or as part of a business transfer, in each case only as permitted by law. We do not sell personal information. We do not “share” it for cross-context advertising.

6. Information we receive directly

The App does not send us your name, email address, or photos.

If you email us, we use the sender address, the message, and any name you include, to reply, to manage the inquiry, and to meet legal obligations. This may become personal data we hold.

7. Purposes of use

We and our processors use information only for:

  • providing and maintaining the App, and carrying out capture, storage, and export that you request
  • determining subscription status, restoring purchases, and providing paid features
  • answering inquiries
  • preventing abuse, handling faults, and complying with law
  • responding to requests for disclosure, correction, deletion, and similar rights under this Policy

We do not use information for other purposes. If we need a new purpose, we will update this Policy first and obtain any consent required by law.

8. Legal bases (EEA and United Kingdom)

If you are in the European Economic Area or the United Kingdom, we process information on these bases:

  • performance of a contract, to provide the features you request (on-device photo handling and subscription status)
  • legitimate interests (answering inquiries and running the service securely), only where those interests are not overridden by your rights
  • compliance with legal obligations
  • consent, where the law requires it

Transfers outside the EEA or UK (to RevenueCat in the United States) are made with contractual safeguards and in accordance with applicable law.

9. Security

Photos and in-app settings are stored in the App’s private storage, which the operating system isolates from other apps.

Information sent off the device for the subscription check uses encrypted transport (HTTPS / TLS). We do not retain payment instrument numbers.

When we hold inquiry emails, we limit access to what is needed to handle them.

10. Retention and deletion

Photos and settings on the device are removed when you delete them in the App, or when you delete the App. We do not keep copies. If the operating system retains caches or backups, that is governed by the OS.

We keep inquiry emails for as long as needed to reply and keep a record, then delete them. If we must retain them for law or a dispute, we keep them only until that purpose ends.

Purchase records held by RevenueCat, Apple, and Google may be kept under those companies’ rules and as required for accounting and law. To ask us to delete subscription-related information we can control, use the contact in Section 12. We will act as required by law, including instructing our processor where appropriate.

The App does not create accounts, so there is no account-deletion flow. The authoritative way to remove on-device data is to delete it in the App or delete the App.

11. Your choices

You can refuse or revoke camera and photo-library access in system settings. Features that do not need those permissions remain available.

You can cancel the subscription in the store account settings.

You do not need an analytics, advertising, or tracking opt-out, because the App does not perform those activities.

12. Access, correction, deletion, and other requests

To ask us to disclose, correct, delete, stop using, stop providing to a third party, or port information we hold, write to the address below. After we confirm your identity, we will respond without undue delay as required by law.

Photos and settings on the device are not held by us; delete them in the App. To request deletion of purchase records processed by RevenueCat, use the same contact.

Where the law of the EEA, the United Kingdom, California, or another place gives you further rights (access, correction, deletion, restriction, objection, withdrawal of consent, lodging a complaint with a supervisory authority, or opting out of sale or sharing), you may exercise those rights. We do not sell personal information and we do not share it for cross-context advertising.

Please contact info@tenpera.com first. If we cannot resolve the matter, you may complain to the Personal Information Protection Commission of Japan or to the supervisory authority where you live.

13. Children

The App is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe a child has provided personal information, contact us. We will delete it once we have confirmed the request.

14. Changes

If we change this Policy, we will update this page and the date at the top. For material changes, we will try to give reasonable notice. Use of the App after a change is posted is subject to the updated Policy.

15. Governing law

This Policy is governed by the laws of Japan. If a lawsuit arises between you and us about the App, the courts with jurisdiction over our head office have exclusive jurisdiction in the first instance, unless applicable law requires a different forum or gives you non-waivable rights.
