Privacy Policy

Established: October 29, 2026
Last updated: November 9, 2026

This is an English translation of the Japanese original. If the two differ, the Japanese text prevails.

Introduction

This policy explains what information is handled, and how, on Essel's website "essel.app" (the "Site") and through contact emails. We will provide a separate privacy policy for each Essel app (see "Policies for each app" below). We have tried to keep this short and honest.

Who we are

Name: Essel
Business: App development studio (Japan)
Contact: info@essel.app

Information collected through the Site

The Site is static. It does not use analytics, advertising, cookies set by Essel, or forms.

Web fonts

The Site loads web fonts from Google Fonts. When you open a page, your browser sends requests directly to Google (fonts.googleapis.com / fonts.gstatic.com), and information such as your IP address and user agent is sent to Google. For details on how Google handles this information, see Google's Privacy Policy.

Hosting

The Site is served by Cloudflare Pages. Cloudflare may process access logs (such as IP addresses) to keep the service secure and to deliver content. For details, see Cloudflare's Privacy Policy. Essel itself does not collect or keep these logs.

Browser storage

The Site may store a small amount of data in your browser's localStorage, such as the number of visits and the stars you have lit, only for on-screen effects. This data stays on your device and is not sent to any server. You can delete it at any time from your browser settings.

Policies for each app

We will provide a separate privacy policy for each Essel app. What information an app handles, which third-party services it uses, which permissions it asks for, and the age it is meant for all differ from app to app. Each app's policy will be available from its store listing.

If this page and an app's policy differ, the app's policy prevails for that app.

No apps have been released yet, so there are no app-specific policies at this time. We will add a page for each app when it is released.

Principles common to all our apps

• We do not include advertising or analytics SDKs unless the app's own policy says so.
• Data you enter into an app is stored only on your device, unless the app clearly says otherwise.
• We request permissions only when they are needed for a feature.
• If an app uses third-party services, this will be stated in that app's policy.

Information you send us by email

If you contact us by email, we use your email address and message only to reply, to reproduce reported bugs, and to contact you if needed. We keep them for one year after our correspondence ends, and then delete them.

Requests about your information

If you would like us to disclose, correct, delete, or stop using information we hold about you, please email info@essel.app. After verifying your identity, we will respond without undue delay in accordance with applicable law.

Disclosure to third parties

We do not provide the information you give us to third parties, except as provided by law. Service providers needed to display or deliver the Site, such as Google and Cloudflare, may receive information through technical processes, as described in the relevant sections above.

Children's privacy

The Site is not intended for children. We do not intentionally collect information through the Site from anyone under 13.

Some Essel apps may be used by children. Each app's policy will describe its intended age group and how it handles children's information. Parents and guardians, please read the app's policy before using it.

Changes to this policy

We review this policy as needed. If we revise it, we will update the "Last updated" date on this page.

Governing law

This policy is interpreted in accordance with Japanese law. This policy was originally written in Japanese, and if there is any doubt about its interpretation, the Japanese version prevails.
