Privacy Policy

Effective: September 27, 2026

This English version is provided for convenience. If it differs from the Japanese version, the Japanese version prevails.

Artlet Lab ("we", "us") sets out this privacy policy for how information is handled in the mobile application "BoothLog" (the "App").

2. Our approach

What you record in the app (checkouts, tallies, items, prices, images, journal entries, settings and so on — "your records") is stored only on your device.

We do not collect your records. Your records are never sent to our servers. The app has no account registration.

The app connects to the internet only to show ads and to check purchases (see section 4).

3. Information stored on your device

Your records are stored on your device and are deleted when you delete the app.

When you choose "Export", the app turns your records into a file and hands it to the destination you choose. You decide where it goes; we are not involved.

4. Information sent to external services

The app communicates with external services only for the following purposes.

RecipientInformation sentPurpose
Google AdMob (Google LLC)IP address, device type and OS, app information, ad views and taps, etc.Showing ads, preventing fraud, measuring ad performance
App Store (Apple Inc.) / Google Play (Google LLC)Information needed to process a purchase and to check whether you have purchasedPurchasing paid features and checking purchase status

Ads. Ads are shown only if you have not made the purchase. Only non-personalized ads (ads not based on your interests) are shown. The app does not use advertising identifiers (Android Advertising ID or iOS IDFA). On iPhone, the app does not ask for permission to track you across other apps and websites.

For how Google handles information, see How Google uses information from sites or apps that use its services.

Purchases. Payments are processed by Apple or Google. We do not receive your credit card or other payment details. The app only checks whether you have made the purchase and stores the result on your device.

Transfers abroad. The recipients above are companies based in the United States, where data protection rules may differ from those in Japan.

Your records themselves are not sent to these recipients either.

5. Device features

The app does not collect your location. On Android, a "location" item may be shown because of how nearby devices are discovered, but the app neither collects nor stores your location.

6. Sharing with other people

Records you share through "Record together" or by handing over a file are stored on the other person's device. We cannot delete records that have been passed to someone else's device.

7. Analytics

The app does not use analytics or any tools for collecting usage data.

8. Age

The app is not directed at children under 13.

9. Your requests

Since we do not hold your records, you can view, correct and delete them within the app. For questions about this policy, please contact us at the address in section 1.

10. Changes to this policy

We may change this policy. If we make important changes, we will announce them on this page.
