Tegaki Support

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

This is a translation for convenience. The Japanese version prevails.

Summary: This page collects the contact information and the frequently asked questions for “Tegaki”, an app for iPad and iPhone. The developer is an individual and usually replies within about 3 business days. The developer helps with how to use the App and with bugs, but some things are out of the developer's reach, such as refunds and problems with your Google account itself. Your handwriting is saved only in your iCloud, so the developer cannot see or restore its contents.

Support is provided by one developer in Japan. You can write in English or Japanese. Replies are prepared with the help of machine translation and may take a few business days.
Example subject: “Tegaki: events do not appear”
Information that helps us solve the problem sooner:
- your device (iPad or iPhone) model and its iOS or iPadOS version (Settings > General > About)
- the version of the App (shown in the App's settings)
- what you did and what happened (with screenshots, if possible)
- the type of your Apple Pencil (1st generation / 2nd generation / USB-C / Pro)
You do not need to send the contents of your handwriting or events by email. If you do send them, they are deleted once your question has been dealt with (Section 12 of the Privacy Policy).

Reply time

The first reply comes within about 3 business days (not counting Saturdays, Sundays and Japanese public holidays). The App is run by one person, so replies may be late during longer holidays. In that case, this page will say so.
If a solution takes time, you will be told how it is going.

What the developer cannot help with

Refunds: Apple decides on refunds. Please request one at https://reportaproblem.apple.com/. The developer cannot process refunds. The right of withdrawal for people in the EU (European Union) is also handled by Apple (see “How do I cancel a purchase in the EU?” below).
Restoring handwriting: Your handwriting exists only on your device and in your iCloud, and the developer can neither see it nor take it out. The developer cannot bring back handwriting that has disappeared.
Problems with your Google account, iCloud or Apple Account itself (passwords, two-factor authentication, full storage and so on): please ask Google or Apple support.
Breakdown or repair of an iPad, iPhone or Apple Pencil
Bugs in the Calendar app on your device itself (the events in the App are what the Calendar app on your device has synced. Anything that does not appear in the Calendar app does not appear in the App either.)
Custom work (changes for companies, features for particular people)

Frequently asked questions

How do I show my Google Calendar events?

The App does not connect directly to Google. When you add your Google account in the Settings app on your device, iOS or iPadOS syncs the calendars, and the App shows them.

Settings > Apps > Calendar > Calendar Accounts > Add Account > Google (on iOS and iPadOS 17: Settings > Calendar > Accounts)
Sign in to Google and turn on the switch for Calendars (you can turn off Mail and Contacts if you do not need them)
Open the built-in Calendar app on your iPad or iPhone, and check that your Google events appear
Open Tegaki, and when you are asked for access to your calendars, choose “Allow Full Access” (the reason is in the Privacy Policy)
In the App's settings, check that the calendars you want to show are ticked

Events do not appear

Please check these in order.

Does the event appear in the built-in Calendar app on your iPad or iPhone? If not, it is a sync problem (check the steps above, and Settings > Apps > Calendar > Calendar Accounts > Fetch New Data).
Is Settings > Privacy & Security > Calendars > Tegaki set to Full Access?
Is that calendar ticked in the App's settings?
Are you looking at the right date, week or month? (Tap “Today” at the top of the screen to go back to today.)
If it still does not appear, close the App once and open it again.

Handwriting does not sync with my other device

Are both devices signed in to iCloud with the same Apple Account?
Is Settings > your name (your Apple Account; called Apple ID on iOS and iPadOS 17) > iCloud > (See All) > Tegaki turned on?
Is there iCloud storage left? (Handwriting uses your iCloud storage.)
Are both devices connected to the internet? Sync can take from a few seconds to a few minutes. Opening the page again brings in the changes.
Even if you write on the same page on both devices at the same time, the App is made to keep the strokes from both (please contact us if any disappear).

How do I cancel?

Settings > your name > Subscriptions > the subscription of this App > Cancel Subscription (on iOS and iPadOS 17, your name opens Apple ID). Apple's guide: https://support.apple.com/en-us/118428
After you cancel, you can keep using the App until the end of the period you have paid for. After that, it becomes “View Only” (Terms of Service, Article 5).
If you cancel during the free trial, you are not charged. Please cancel at least 24 hours before the trial ends.

How do I cancel a purchase in the EU?

If you live in the EU (European Union), the law gives you a right of withdrawal. Within 14 days of receiving your receipt, you may be able to cancel your first subscription without giving a reason (this does not apply to each renewal). Apple carries out this process, and the developer cannot.

Please follow the steps under “Right of withdrawal” in 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). You choose the order from the purchase history of your Apple Account.
For digital items, this right can end once the supply has started. Apple decides whether the purchase can be canceled.
Canceling a subscription is a separate step (see “How do I cancel?”).

When the free trial ends, does my handwriting disappear?

No. You can still view your events and handwriting. Only writing, erasing and moving anything new, creating and editing events, and importing from the web version stop (Terms of Service, Article 5). Exporting handwriting (Settings > Data > “Export Handwriting”) also works in View Only. If you subscribe again, everything works as before.

How do I restore my purchase?

In the App, tap Settings > Purchase > “Restore Purchases”. Make sure you are signed in with the same Apple Account you used when you bought. If you are told that there is no purchase to restore, check whether this App is listed in Settings > your name > Subscriptions (on iOS and iPadOS 17, your name opens Apple ID).

It says there is a problem with my payment

If renewing a paid period fails, for example because your card has expired, Apple tries to charge again during a grace period of up to 16 days. You can keep using the App during that time. Please update your payment method in Settings > your name > Payment & Shipping (on iOS and iPadOS 17, your name opens Apple ID). When the grace period is over, the App becomes View Only, and it returns to normal when the payment goes through. If the first payment when a free trial turns into a paid period fails, there is no grace period, and the App is View Only until the payment is confirmed.

How do I delete all my data?

Handwriting (including iCloud): In the App, Settings > “Erase All Handwriting on This Device”. If iCloud can be used, the handwriting in iCloud is erased too, and it also disappears from your other devices (you are asked to confirm twice).
Deleting only the iCloud data by hand: Settings > your name > iCloud > Manage Account Storage > Tegaki > Delete Data (on iOS and iPadOS 17, your name opens Apple ID)
Data on the device: it is deleted when you delete the App (the data in iCloud remains).
Events: events created in the App are ordinary calendar events, so delete them in the Calendar app or in Google Calendar.
The App's data does not reach the developer, so there is no need to ask the developer to delete it. If you want an email you sent to support deleted, please let us know by email.

When I change my iPad or iPhone

On the new device, sign in to iCloud with the same Apple Account
Install the App from the App Store (if you have bought it before, it installs at no charge). With the same Apple Account, your subscription carries over automatically. If it does not, tap “Restore Purchases” in the App.
When you open the App, your handwriting is brought in from iCloud (this can take a few minutes, depending on the amount)
To show your Google events, add your Google account in the settings of the new device too (the steps above)
To be safe, before you let the old device go, connect it to the internet and open the App once, so that no handwriting is left unsent to iCloud

I want to switch between the pen and the eraser with a double-tap or squeeze on Apple Pencil

In Settings > Apple Pencil, you can choose what a double-tap (2nd generation and Pro) and a squeeze (Pro) do. The App follows the action you choose there. If you choose “Switch between current tool and eraser”, it switches between the pen and the eraser. With an Apple Pencil that has no double-tap (1st generation, USB-C), switch with the toolbar at the bottom of the screen (the “tap with two fingers” switch of the web version is not in the app version).

Can I use it on iPhone or Mac?

You can use it on iPhone (iOS 17 or later). On iPhone, you write with your finger (“Draw with Finger” in the toolbar). If you use the iCloud of the same Apple Account on iPad and iPhone, your handwriting syncs. It also opens on a Mac, but there it is meant for supplementary use (checking and simple writing). A Mac has no Apple Pencil, so handwriting is done with a trackpad or mouse.

I want to move my handwriting from the web version to the App

The handwriting of the web version (“手書きカレンダー”, which runs in a browser) is saved in Google Drive, separately from the iCloud of the app version. You can import it with these steps.

In the settings of the web version, press “手書きを書き出す（iPad アプリ用）” (export handwriting, for the iPad app) → one JSON file goes into the Files app
In the App, choose that file in Settings > Data > “Import from the Web Version”
It goes into the month, week, day and year pages, at the same places as in the web version

Importing the same file twice does not make duplicates. Strokes you erased in the web version do not come back. Please import while you are subscribed (or in the trial). After that, the web version and the app version do not sync.

This import supports two formats. Besides the JSON exported by the web version, you can also import a data file (JSON) exported by this App itself, from the same “Import from the Web Version” (see the next question).

How do I export my handwriting?

In the App, tap Settings > Data > “Export Handwriting”, and choose “Data File (JSON, All Pages)” or “This Page as PDF”. When it is ready, you can use “Share…” to save it in the Files app, or send it by AirDrop or Mail. Exporting works without a subscription.

A data file puts all the handwriting saved on this device (month, week, day and year) into one JSON file, and you can import it again from Settings > Data > “Import from the Web Version” (please import while you are subscribed). Importing the same file twice does not make duplicates. Importing only adds: strokes that you erased in the App after exporting do not come back when you import again (the record of the erasing wins). If you want to put everything back as it was, first erase everything with Settings > Data > “Erase All Handwriting on This Device”, and then import. The data file is for importing back into this App (its contents are readable text (JSON), and the format is described for developers in the design document and README). To keep a copy that people can read, make a PDF of each page. Files up to about 200 MB (tens of thousands of strokes) are expected. Larger files may take a long time to import, or may fail.

A PDF is the page that is open now, as one sheet (paper, events, holidays and handwriting; the line for the current time is not included).

Tap “Hide” at the right end of the toolbar, and the toolbar becomes a small round button at the bottom left. Tap the tool mark on the round button to bring the toolbar back; it hides again automatically when you start writing on the paper. The ↶ on the round button is “Undo”. Touch and hold the round button to move it to the bottom right, or to go back to always showing the toolbar. This setting is remembered on each device.

How do I zoom in and out?

Spread two fingers to zoom in, and pinch to zoom out. Month and year pages open at the same size, no matter how many events or how much handwriting they have. Pages with many events or a lot of handwriting can be scrolled down (with two fingers when “Draw with Finger” is on). When you pinch to zoom out, you can see the whole calendar. The device remembers the zoomed-in size for each page type. It does not remember the zoomed-out size.

How much can I write on one page?

You can write up to 19,000 strokes on one page (when you go past 15,000, you are told once). The Notes area of the month page and the “Free Notes” area below 24:00 on the day page are open all the way down from the start. Their length has a limit (about 4 screens on the month page of an iPad). You can check the current number in Settings > About > “Page with the Most Strokes”.

What if my iPad and iPhone have different versions?

The “Free Notes” area below 24:00 on the day page is a feature from version 1.1. On a device still on 1.0 or 1.0.1, it is not shown, but it has not been deleted (it appears when you update that device). Strokes written near 24:00, and strokes moved below 24:00 with the lasso, are also not visible on older versions (they have not been deleted). Please update both your iPad and your iPhone to the latest version. Note that if you use “Erase All Handwriting” on a device with an older version, the handwriting in that area is erased too.

How do I change the display language?

The App's display switches to match the language of your device. It supports 10 languages: Japanese, English, Chinese (Simplified and Traditional), Korean, French, German, Spanish, Italian and Portuguese. On devices set to any other language, the App is shown in English.

There is no language item in the App's own settings. To use a different language for the App only, choose it in the Settings app on your device:

Settings > Apps > Tegaki > Language (on iOS and iPadOS 17: Settings > Tegaki > Preferred Language)
On a device shown in Japanese: 「設定」›「アプリ」›「てがきカレンダー」›「言語」 (on devices in Japanese, the App's name is “てがきカレンダー”)

If the item is not there, it appears after you add the language you want to use in Settings > General > Language & Region. When you add it, if you are asked which language to use for the display of your device, choose to keep your current language.

Changing the language does not change the shape of the paper or the position of your handwriting (you can choose the week start in the App's settings).

How do I change the holiday country?

Choose it in the App's Settings > Holidays > “Holidays to Show”.

Automatic: shows the holidays of the country of your device's region (Settings > General > Language & Region > Region).
A country or region: choose one from the list. For countries whose holidays differ by state or region, such as the United States, Germany and Canada, choosing a state or region next adds the holidays of that region. If you do not choose a state or region, only the holidays common to the whole country are shown.
None: no holidays are shown.

If you have been using the App, it stays on “Japan” after you update to 1.2. The holidays of Japan are calculated by the App itself, as before (checked against the announcements of the Cabinet Office of Japan).

About holidays outside Japan:

The holiday data comes from python-holidays (MIT License). The full text of the license is in the App, in Settings > About > “Open Source Licenses”.
Some holidays, such as those based on the lunar calendar or the Islamic calendar, are estimates, and “(est.)” is added after their names. They may fall on a different day from the actual one.
In countries where the government decides the days off and the substitute working days in an announcement each year, such as China, the settings row says that a year is an estimate made before the announcement, when that year's announcement is not yet in the data. The days off for that year may differ from the actual announcement.
When the settings row says that there is no holiday data, the App has no holiday data for that country or region (no holidays are shown). When it says that there is no data from a certain year on, the holiday data from that year onward is missing.
Holiday names are shown in the display language when the data has names in it, and otherwise in English or another language. The names of states and regions are written as they are in the data (in English or the local language).
Holidays outside Japan are reference information (Terms of Service, Article 9). The holiday data is built into the App, and it is renewed with updates of the App.

The holiday setting is saved only on this device (you can choose separately on your iPad and your iPhone). Changing the holiday setting does not change the shape of the paper or the position of your handwriting.

If you find a mistake in a holiday, please tell us by email at the contact above, with the country or region, the date and the correct name of the holiday.

My week handwriting is gone. What should I do?

Handwriting on week pages is saved separately for weeks that start on Monday and weeks that start on Sunday. Check that Settings > Week Starts On is the same as when you wrote it. This setting is per device, so use the same setting on your iPad and iPhone to see the same week handwriting. Switching never deletes handwriting. Handwriting in a month page's cells for days of the previous or next month also comes back when you switch back. Words written across a weekend appear split into a Saturday part and a Sunday part when weeks start on Sunday. They join up again when you return to Monday.

Known limitations

Item	Details
Colors of single events	Colors given to single events in Google Calendar cannot be shown. Events are shown in the color of their calendar (because the sync of iOS and iPadOS brings only one color per calendar).
Sync interval	How often Google events reach your device depends on the “Fetch New Data” setting of iOS and iPadOS. With “Automatically”, new data may be fetched only while the device is charging and on Wi-Fi. To see changes right away, choose a setting such as “Every 15 Minutes”, or open the Calendar app and pull down to refresh.
Features only in Google	Email notifications for events, creating new Google calendars, and Google Tasks are not supported.
Calendar permission	iOS and iPadOS have no permission for only reading. Even just showing events needs “Full Access”.
iCloud needed	Syncing handwriting needs a sign-in to iCloud. Without signing in, you can still use the App on the device only.
Handwriting across cells	Handwriting is saved for each date cell. When the height of the cells changes because more all-day events are added, strokes written across cell borders may look slightly out of place.
Relation to the web version	The web version and the app version are separate apps, and their handwriting does not sync.
