Yoyaco Privacy Policy

Developer: Toshihiro.nakao
Effective date: October 31, 2026

Toshihiro.nakao ("we", "us") has established this Privacy Policy to explain how the iOS / iPadOS app "Yoyaco" (the "App") handles your information.

1. Our Approach

The App helps shops manage reservations and customers at the front desk. Everything you enter stays on your device (and in your own iCloud if you turn on sync). We never receive any of it.

• The App does not send information to our servers (we do not operate any)
• No account or sign-in is required
• There is no advertising, usage analytics, or tracking
• The App contains no third-party SDKs

2. Information the App Handles

The App stores the following information that you enter, and uses it to manage reservations and work out open time slots.

• Customer details: membership number, name and phonetic reading, phone number, email address, date of birth, and notes
• Reservation details: date and time, status (tentative, confirmed, visited, cancelled, and so on), staff member, menu and options, and notes
• Staff and menu details: names, display colors, days off and working hours, durations, and preparation and cleanup times
• Shop settings: shop name, business type, opening hours and breaks, closed days, slot length, and how many guests can be served at once
• App settings: whether setup is complete, whether to use sync, suggestions you chose to skip, and similar preferences

The record that lets you undo recent actions is kept in memory only while the App is running and is discarded when you quit the App.

About your customers' personal information

You will enter personal information about your shop's customers into the App. As the party collecting that information from your customers, you are responsible for handling it properly, including explaining to them how it will be used, in line with applicable privacy laws. We cannot receive or view any customer information you enter.

3. Where Your Data Is Stored

• On your device: All information is stored on your device. The App works without a network connection.
• iCloud (when sync is turned on with Premium): To keep your own devices signed in to the same Apple Account in sync, the data is stored in the private area of your iCloud. Only you can access this area; we cannot. You can turn sync off in Settings.
• Device backups: Depending on your device settings, the data may be included in iCloud Backup or in backups to your computer.

Deleting the App removes the data stored on your device. Data synced to iCloud stays in iCloud (see "8. Deleting Your Data" for how to remove it).

4. Access to Device Features

The App does not ask for access to your camera, photos, location, microphone, contacts, or calendars.

• Background updates: Only when iCloud sync is in use, the App receives silent notifications from iCloud and updates in the background so that changes made on your other devices come through. The App does not send notifications that appear on screen.
• Checking for new versions: To see whether a new version is available on the App Store, the App queries Apple's public App Store lookup service at most once every 12 hours. It sends only the App's identifier and the country (Japan), never customers, reservations, or anything else you enter. The query goes to Apple; nothing is sent to us.

5. On-Device Processing

• Search: So that you can find reservations and customers from your device's search, the App adds reservation details to a search index on your device. The index stays on your device and is never sent to us.
• Siri and Shortcuts: When you check or make a reservation through Siri or Shortcuts, the App looks up and saves reservations on your device. Speech recognition is performed by Apple and handled under Apple's privacy policy. We never receive what you say.

6. In-App Purchases

Payment for Premium (a one-time purchase) is processed by Apple through the App Store. We never receive your credit card or other payment details. The App only receives the purchase record from the App Store to confirm whether you have bought Premium.

7. Sharing With Third Parties

Because we do not receive the information handled in the App, we do not share it with any third party. Even if disclosure were requested under law, we could not disclose information we do not hold.

8. Deleting Your Data

• You can delete customers and reservations one at a time in the App. Deleting a customer also deletes all of that customer's reservations.
• "すべてのデータを削除" (Delete All Data) in Settings removes all customers, reservations, staff, and menus at once (shop settings such as opening hours are kept).
• When sync is on, deletions in the App are also applied to your other synced devices and to iCloud.
• Deleting the App removes the data on your device. To remove data left in iCloud, open your device's Settings, go to iCloud storage management, and delete the App's data.

9. Children

The App is a business tool for shops and is not directed at children under 13.

10. Changes to This Policy

We may update this Policy when the App's features change or when laws are revised. Any updated Policy takes effect when it is posted on this page.

11. Information We Receive When You Contact Us

The contact form on the support page is provided by Google Forms (Google LLC). What you enter there (such as the email address to reply to and your message) is used only to respond to you and to investigate problems and improve the App, and is not shared with third parties except where required by law. We delete it once we no longer need it after your inquiry has been handled. Google's privacy policy also applies to the form. Using the App never sends this information to us.
