Last updated: May 20, 2026

This Privacy Policy explains how Dome ("the app") handles your information. Dome is developed and operated by Back After Sento, an independent app developer based in Japan ("we," "us," or "our").

We built Dome to be private by design. The short version: Dome does not collect your personal information, and we have no access to the contents of your home data. The longer version is below.

The short version

  • We do not collect, store, or have access to your personal information.
  • We do not run servers that receive your home data. Your data lives on your device.
  • If you subscribe, your data can sync through your own Apple iCloud account, which is governed by Apple's privacy terms — not ours. We cannot see it.
  • We do not use analytics, advertising, tracking, or marketing tools.
  • We do not sell, rent, or share your information with anyone.

What data Dome stores, and where

When you use Dome, you create data such as your home and item names, maintenance tasks and their history, notes, photos you add, parts and manuals you record, and your in-app preferences.

This data is stored locally on your device.

If you are a subscriber, this data may also be synced to your own private Apple iCloud account using Apple's CloudKit service. This sync happens between your devices through Apple's infrastructure. We do not operate this infrastructure, we are not sent a copy of your data, and we cannot access the contents of your iCloud data. Apple's handling of iCloud data is governed by Apple's Privacy Policy.

For free users, a very small piece of technical information (such as whether a shared home's owner has an active subscription) may sync through iCloud so that shared homes work correctly. This contains no personal information about you and no contents of your home data.

Information we do not collect

Dome does not collect or transmit any of the following to us or to any third party:

  • Your name, email address, phone number, or account credentials
  • Your device location
  • Your contacts
  • Analytics, usage statistics, or behavioral data
  • Advertising identifiers or tracking data
  • The contents of your home, items, tasks, notes, or photos

Dome does not require you to create an account with us. We have no login system and no user database.

Photos

If you add a photo to an item, that photo is stored on your device and, for subscribers, in your own iCloud account along with your other data. Photos are never uploaded to us or to any third party.

Scanning

Dome may let you scan a label or model number to help fill in item details. This scanning happens entirely on your device using Apple's on-device technology. No image or scan data is sent to us or to any third party.

Notifications

Dome uses local notifications to remind you about maintenance tasks. These notifications are scheduled and delivered entirely on your device. They are not sent through any server and do not transmit information about you.

Sharing a home

If you subscribe, Dome lets you share a home with other people (for example, your partner or housemates) using Apple's built-in sharing technology (CKShare). When you share a home:

  • The people you invite are identified by their own Apple iCloud accounts.
  • Sharing is handled through Apple's infrastructure. We do not see who you share with or what is shared.
  • The people you invite can view and update the shared home. We do not control or monitor this activity.

You can stop sharing or remove participants at any time from within the app.

Subscriptions and payments

Dome offers optional paid subscriptions and a one-time purchase. All payments are processed by Apple through the App Store. We never see or store your payment details, credit card information, or billing address. Apple's handling of your purchase information is governed by Apple's terms and privacy policy.

We receive only the anonymous subscription status that Apple provides (whether a subscription is active), which the app uses to enable paid features. This is not linked to your identity by us.

Diagnostics

If you have enabled "Share With App Developers" in your device's iOS settings, Apple may share aggregated, anonymized crash and diagnostic reports with us through App Store Connect. This is a feature provided and controlled by Apple, not by Dome. These reports help us fix bugs and do not identify you. You can turn this off in your device's privacy settings at any time.

Data retention and deletion

Because your data is stored on your device (and, for subscribers, in your own iCloud account), you are in control of it.

  • To delete your data, delete it within the app or delete the app from your device.
  • For subscribers, you can also remove Dome's data from your iCloud account through your device's iCloud settings.
  • You can export your data at any time from within the app. Export generates a file on your device; nothing is transmitted to us.

Because we do not hold your data, we cannot delete it on your behalf — but you can delete all of it yourself at any time using the methods above.

Children

Dome is not directed to children and is not intended for use by children under the age of 13. We do not knowingly collect personal information from children. Because we do not collect personal information from anyone, this applies to all users regardless of age.

Your rights

Because we do not collect or hold your personal information, most data-rights requests (such as requests to access, correct, or delete data we hold about you) do not apply — there is nothing for us to access, correct, or delete. You remain in full control of your data on your own device and in your own iCloud account.

California residents

If you are a California resident, the California Consumer Privacy Act (CCPA) gives you certain rights regarding your personal information. We do not collect, sell, or share personal information as defined by the CCPA. We do not have personal information about you to disclose or delete.

Residents of Japan

In accordance with Japan's Act on the Protection of Personal Information (APPI), we confirm that we do not acquire, hold, or use personal information through the Dome app. We do not provide personal information to third parties.

Changes to this policy

We may update this Privacy Policy from time to time. If we make material changes — for example, if we introduce optional analytics or new features that involve data collection — we will update this page and revise the "Last updated" date above. Any future data collection will be optional and clearly disclosed.
