Tegaki Terms of Service

Tegaki (App) / Last updated: November 6, 2026

Effective date: the date the App was released on the App Store

This is a translation for convenience. The Japanese version prevails. This does not limit rights that you cannot waive under the consumer protection laws of the country where you live.

日本語版（正本）

Summary: This is a paid app for individuals (a subscription) that lets you write by hand, with Apple Pencil or your finger, over the events in the Calendar app on your iPad or iPhone. There is no account to create. Your handwriting and settings are saved only on your device (iPad or iPhone) and in your own iCloud. The developer cannot see their contents. Apple handles billing, cancellation and refunds. The developer makes every effort to support new versions of iOS and iPadOS, but features may change when Apple's or Google's systems change. If the App is discontinued, you will be told 90 days in advance. You can export your handwriting at any time. Of course, the developer is not exempt from liability for damage caused intentionally or through serious carelessness. These terms follow the laws of Japan (this does not limit rights that you cannot waive under the consumer protection laws of the country where you live).

Article 1. About these terms

1. These terms are the rules for using “Tegaki” (てがきカレンダー; the “App”). By downloading the App from the App Store, or by starting to use it, you agree to these terms.
2. The license to use the App is Apple's standard license agreement (Licensed Application End User License Agreement, https://www.apple.com/legal/internet-services/itunes/dev/stdeula/). These terms add the details of the service, the fees and the scope of responsibility. If the two conflict, Apple's agreement prevails in matters between you and Apple.
3. The App is available in the countries and regions where it is offered on the App Store. The App Store shows which countries and regions these are.

Article 2. Supported devices and OS

1. The App works on iPad with iPadOS 17 or later and on iPhone with iOS 17 or later. For handwriting, we recommend an iPad with Apple Pencil (on iPhone, you mainly write with your finger).
2. The App can also be opened on a Mac (with Apple silicon), but this is meant for supplementary use (such as checking events and handwriting), and the same experience as on iPad is not guaranteed. A Mac has no Apple Pencil, so handwriting is done with a trackpad or mouse.

Article 3. What the App provides

The App provides roughly the following features. The details are described in the App Store description and on the support page.

1. Handwriting: You can write freely on the day, week, month and year pages with the pen, marker, eraser and lasso (to circle and move). Handwriting is saved linked to the date cells, so even when a cell grows because more all-day events are added, the handwriting follows the place where you wrote it.
2. Showing and creating events: The App shows the events in the Calendar app on your device (events of the accounts added in the Settings app, such as iCloud and Google). All-day events are all shown; none are left out. You can also create events by tracing over or circling your handwriting.
3. iCloud sync: Your handwriting syncs through your iCloud (private database) between devices signed in with the same Apple Account.
4. Showing public holidays, importing handwriting from the web version “手書きカレンダー”, and exporting handwriting (a data file (JSON) of all the handwriting saved on this device, and a PDF of the page that is open; Settings > Data > “Export Handwriting”).

The App does not communicate directly with Google's servers. Google Calendar events are shown after iOS or iPadOS syncs them through the Google account added in the Settings app on your device.

Article 4. No account needed; your data stays with you

1. The App has no accounts managed by the developer (no registration or login).
2. Your handwriting, your settings and the saved copy of your events are stored only on your device and in your own iCloud. The developer does not receive them and cannot view or restore them.
3. The space used in iCloud counts toward your own iCloud storage (this is how Apple's system works).
4. For details, please read the Privacy Policy.

Article 5. Fees (subscription)

1. What you buy: The features of the App are provided by subscription. The plans and prices are as shown in the App Store and on the purchase screen. Monthly: ¥300 (every month). Yearly: ¥2,400 (every year; ¥200 per month). Both include tax. The price shown in the App Store is the one that applies. Both come with a 14-day free trial (item 4).
2. Automatic renewal: The subscription renews automatically unless you cancel it at least 24 hours before the end of the current period, and the fee for the next period is charged to your Apple Account.
3. Apple handles billing, cancellation and refunds:
   • Apple charges the fee to your Apple Account. The developer does not receive card details or similar information.
   • You can cancel in the Settings app on your device: tap your name (your Apple Account; called Apple ID on iOS and iPadOS 17), then Subscriptions. After you cancel, you can keep using the App until the end of the period you have paid for. If you cancel in the middle of a period, the rest of that period is, as a rule, not refunded (Apple decides whether a refund is possible. If Apple's terms for your country or the law there say otherwise, those apply.)
   • Refunds follow Apple's rules, and you request them from Apple (https://reportaproblem.apple.com/). The developer cannot give refunds directly.
   • If you live in the EU (European Union), the law gives you a right of withdrawal (a right to cancel a purchase within a set period without giving a reason). Other countries may have a similar right. Apple sets how the period is counted and the conditions, and they are in the Apple Media Services Terms and Conditions for your country. For subscriptions, this applies only to the first subscription, not to each renewal. For digital items, this right can end once the supply has started. The developer cannot carry out these steps, so please follow Apple's steps.
   • The seller of the App's subscriptions is Apple (in Japan, iTunes K.K.). Purchases are made under the Apple Media Services Terms and Conditions (https://www.apple.com/jp/legal/internet-services/itunes/jp/terms.html), and the information required by Japan's Act on Specified Commercial Transactions is Apple's information contained in those terms. As the provider of the App, the developer is responsible within the scope of these terms. In the EU (European Union), the seller is Apple Distribution International Ltd., and purchases are made under the Apple Media Services Terms and Conditions for your country (Irish version: https://www.apple.com/legal/internet-services/itunes/ie/terms.html. For other countries, use “Choose your country/region” on that page).
4. Free trial: If you are new, you can try all the features free for 14 days (once per Apple Account; if you have used the trial before, you are charged when you buy). When the trial ends, it automatically becomes a paid period. If you do not want to move to a paid period, cancel at least 24 hours before the trial ends.
5. After the trial or after cancellation: “View Only”: Even when your subscription is not active, the App does not disappear.
   • You can: view events and handwriting, move between pages and zoom, receive from iCloud, erase all handwriting on this device, export handwriting (data file, PDF), and change settings.
   • You cannot: write, erase or move anything new, create events from handwriting, create, edit or delete events, or import from the web version (you can still edit events in the Calendar app on your device).
   • Exporting handwriting works in View Only. Import (restore) exported data files while you are subscribed.
   • If you subscribe again, everything works as before.
   • The developer does not delete your handwriting or settings, or make them unviewable, because of your subscription status.
   • If there is a problem with your payment when a paid period renews, you can keep using the App during Apple's billing grace period (up to 16 days). This does not apply to the first payment when a free trial turns into a paid period; in that case, the App is View Only until the payment is confirmed.
6. Price changes: When the price changes, you will be told in advance through Apple's system. You may be asked to agree before your subscription renews.
7. Restoring purchases: When you change devices, for example, sign in with the same Apple Account and tap Settings > Purchase > “Restore Purchases” in the App.

Article 6. What you must not do

Please do not do the following.

1. Take apart, modify or analyze (reverse engineer) the App, or copy and distribute, lend or sell it.
2. Use the App to do anything against the law or public order and morals, to infringe the rights of others (such as copyright or privacy), or to cause trouble for others.
3. Use the App in a way that breaks the terms of the services it works with, such as those of Apple or Google.
4. Misuse the App's systems to use paid features without paying.

Article 7. Updates and maintenance

1. The developer is an individual. Support for new versions of iOS and iPadOS and for new iPad and iPhone models is on a best-effort basis. It may not come right away, or it may not be possible.
2. The App depends on Apple's systems (Calendar, iCloud, Apple Pencil and others) and on Google Calendar syncing through iOS and iPadOS. When Apple or Google changes its specifications, features may change or stop working. In that case, the developer will tell you as soon as possible and look into other ways.
3. Support for older versions of iOS and iPadOS may end after notice (the supported OS versions are listed in the App Store description).
4. Features of the App may be added, changed or removed after notice.

Article 8. If the App is discontinued

1. If the App is discontinued, the developer will announce it at least 90 days in advance, in the App and on the support page.
2. A way to export your handwriting (the data file and the PDF in Settings > Data > “Export Handwriting”) is available, and it will be kept working until the end. Your handwriting stays in your iCloud, but it cannot be read once the App is gone, so please export it before the end.
3. Automatic renewal stops when the service ends. Periods you have already paid for are handled under Apple's rules.
4. Events you created in the App are ordinary calendar events in the Calendar app on your device (and in Google Calendar and other services), so they remain even if the App is gone.

Article 9. Disclaimer and limits of liability

1. The App is provided as it is at the time. The developer does not guarantee that it is free of defects in every environment and use, that it works without interruption, or that it suits a particular purpose. Public holidays of countries other than Japan are reference information based on public data (python-holidays), and their accuracy is not guaranteed.
2. The developer is not exempt from liability for damage caused by the developer's intent or gross negligence. Every clause of these terms is to be read in that way.
3. For damage caused by the developer's minor negligence, the developer's liability is limited to the total of the fees you paid for the App in the 12 months just before the damage. This limit applies only to minor negligence, not to intent or gross negligence.
4. The developer cannot control the following, so the developer is not liable for them unless the developer acted with intent or gross negligence:
   • outages, specification changes or the end of services of Apple (App Store, iCloud, iOS and iPadOS) or Google
   • failure or loss of your device, bugs in iOS or iPadOS, network outages
   • loss of data caused by your own actions (deleting, changing accounts, turning off iCloud, and so on)
   • billing, renewal and refunds of App Store subscriptions, which Apple handles and in which the developer cannot take part
5. We recommend keeping copies of important handwriting with device backups and iCloud (and with the data file from “Export Handwriting”).
6. These terms do not limit the rights that Japanese laws, such as the Consumer Contract Act, give you.
7. Paragraphs 1, 3 and 4 do not limit the rights that consumers have under the laws of the country where they live, including rights about defects and rights about liability for damage caused by defective products.

Article 10. Rights

1. The rights to the App (program, design, icon and text) belong to the developer. These terms give you the right to use the App personally; they do not transfer those rights to you.
2. The rights to the handwriting you write and the events you create with the App belong to you. The developer has no rights to them at all (and does not receive them in the first place).

Article 11. Changes to these terms

1. These terms may be revised to follow changes in laws or in features.
2. When the terms change, the developer will announce the new content and the effective date in the App and on the support page at least 30 days before the effective date (except for minor changes and changes in your favor).
3. If you keep using the App on or after the effective date, you are considered to agree to the changed terms. If you do not agree, please cancel your subscription and stop using the App.

Article 12. Governing law and courts

1. These terms are interpreted under the laws of Japan.
2. If a problem arises about the App, we will first try to solve it by talking it through via the support contact.
3. If it is still not solved, the district court or summary court with jurisdiction over the developer's address is the court of first instance. However, this does not prevent you from bringing a case before a court that the law allows you to use as a consumer.
4. Rights that you cannot waive under the consumer protection laws of the country where you live are not limited by these terms.
5. If you are a consumer living in the EU (European Union), the consumer protection rules of the country where you live that cannot be changed by contract apply to you, even though paragraph 1 chooses the laws of Japan. Despite paragraph 3, you can also bring a case before the courts of the country where you live.
