聯絡

WordBook(字裡行間)由一個人開發。有任何問題、錯誤回報或建議,請寄到 candanweng@gmail.com,通常一到兩天內會回覆。

回報問題時,如果能附上這幾項會快很多:使用的裝置與系統版本、發生問題的那本書和玩法,以及當時的畫面截圖。

常見問題

我換了手機/重灌了 App,完整版要怎麼拿回來?

「設定 → 完整版 → 還原購買」,或在付費牆上按「還原購買」。用同一個 Apple ID 或 Google 帳號登入即可,不需要重新付費,也不需要任何帳號或收據。

我的書和進度會跟著一起回來嗎?

不會。App 沒有伺服器,也沒有帳號,所有內容只存在你自己的裝置上。換機或刪除 App 之後,書架、進度、統計、成就與摘句本都要重新開始。這是「不收集任何資料」的代價。

贊助開發者會解鎖功能嗎?

不會。「設定 → 關於 → 贊助開發者」裡的三個項目純粹是自願的心意,不會改變 App 的任何行為,也不會解鎖完整版。要解鎖功能請購買完整版。

完整版是訂閱嗎?

不是。完整版是一次性買斷,不會自動續訂,也不會有任何後續扣款。

匯入 EPUB 失敗怎麼辦?

App 支援標準的 EPUB 2 與 EPUB 3 檔案。有 DRM 保護的檔案(例如從其他電子書商店買的書)無法開啟,這是檔案本身被加密,不是 App 的問題。PDF 與 mobi 目前不支援。

如果是沒有 DRM 的 EPUB 仍然打不開,歡迎寄信告訴我,附上檔案的話我可以直接查。

線上書庫連不上?

書庫的書目來自 Gutendex,檔案來自 Project Gutenberg,兩者都是外部服務,偶爾會有維護或連線問題。除了瀏覽書庫之外,App 其餘功能完全離線可用。

每日挑戰的連續天數斷了?

連續天數以你的裝置時區為準,跨過一整天沒有完成當天的題目就會歸零。手動調整裝置時間不會補回已經斷掉的紀錄。

要怎麼清除全部資料?

「設定 → 關於 → 清除所有資料」會清空書架、進度、統計與摘句本。已購買的完整版不受影響,重新還原即可。刪除 App 同樣會清掉所有資料。

隱私

App 不收集任何個人資料。詳見隱私政策

Contact

WordBook is made by one person. For any question, bug report or suggestion, write to candanweng@gmail.com — replies usually come within a day or two.

When reporting a problem, these details make it much faster: your device and OS version, which book and puzzle type it happened in, and a screenshot of what you saw.

Common questions

I changed phones or reinstalled. How do I get the full version back?

Settings → Full version → Restore purchase, or tap "Restore purchase" on the paywall. Sign in with the same Apple ID or Google account and it comes back at no cost — no account, no receipt needed.

Do my books and progress come back too?

No. The app has no server and no accounts; everything lives only on your own device. After switching phones or deleting the app, your shelf, progress, statistics, achievements and commonplace book start over. That is the cost of collecting nothing.

Does sponsoring the developer unlock anything?

No. The three items under Settings → About → Sponsor the developer are purely voluntary. They change nothing about how the app behaves and do not unlock the full version. To unlock features, buy the full version.

Is the full version a subscription?

No. It is a one-time purchase. Nothing renews and nothing is charged again.

An EPUB will not import.

The app reads standard EPUB 2 and EPUB 3 files. Files with DRM — books bought from other ebook stores, typically — cannot be opened, because the file itself is encrypted. PDF and mobi are not supported.

If a DRM-free EPUB still will not open, write to me; send the file and I can look at it directly.

The online library will not load.

The catalogue comes from Gutendex and the files from Project Gutenberg, both outside services that occasionally go down for maintenance. Everything except browsing that library works fully offline.

My daily streak reset.

The streak follows your device's time zone: miss a full day without finishing that day's passage and it goes back to zero. Changing the device clock by hand does not restore a streak that has already broken.

How do I clear everything?

Settings → About → Clear all data empties the shelf, progress, statistics and commonplace book. A full version you have bought is unaffected — just restore it. Deleting the app clears everything as well.

Privacy

The app collects no personal data. See the privacy policy for details.

Rhythms — Terms of Use

Terms of Use — Rhythms

Terms of Use — Rhythms

Last updated: 15 August 2026

This End User Licence Agreement (“Agreement”) is between you and Candan Weng, an independent developer (“we”, “us”), and governs your use of the Rhythms iOS application (“the App”). By downloading or using the App you agree to it. If you do not agree, do not use the App.

This Agreement is concluded between you and us alone, and not with Apple. We, not Apple, are solely responsible for the App and its content.

1. Licence

We grant you a personal, non-transferable, non-exclusive licence to use the App on any Apple-branded device that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions. The App is licensed to you, not sold.

You may not sell, rent, sub-licence or redistribute the App, nor reverse engineer, decompile or disassemble it except to the extent that applicable law expressly permits despite this restriction.

2. Rhythms Pro and tips

The free version of the App limits how many tasks you may keep. Rhythms Pro removes that limit and adds backup and restore. Pro is available three ways, all unlocking identical features:

PurchaseLengthPrice
Rhythms ProOne-off, permanentUS$19.99
Rhythms Pro (Yearly)1 year, auto-renewingUS$9.99 per year
Rhythms Pro (Monthly)1 month, auto-renewingUS$0.99 per month

Prices are set per region by the App Store; the amount shown on the Apple confirmation screen is the amount charged.

Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically for the same period unless auto-renew is turned off at least 24 hours before the current period ends; your account is charged for renewal within 24 hours before that point. You can manage or cancel a subscription in Settings › Apple Account › Subscriptions. Cancelling stops future renewals; it does not refund the period already paid for.

The one-off purchase never expires and never renews. Buying it while a subscription is active does not automatically cancel the subscription — cancel it yourself in the Subscriptions screen.

Tips are optional consumable purchases that unlock nothing. They are a voluntary thank-you and are not refundable by us.

All purchases are processed by Apple. We cannot issue refunds; requests go to Apple at reportaproblem.apple.com.

3. Your data and backups

Your tasks stay on your device. We operate no server, hold no copy of your data, and cannot recover it for you. See the Privacy Policy for detail.

You are responsible for your own backups. Deleting the App, losing the device, or a device or operating-system fault will destroy your data permanently. The App provides Settings › Backup › Export a backup for this purpose. We are not liable for lost tasks, history or backup files.

Reminders are scheduled locally by iOS. Their delivery depends on iOS settings, notification permission, Focus modes, low-power states and system limits on how many notifications an app may schedule. We do not guarantee that any given reminder will be delivered, and the App must not be relied on where a missed reminder would be harmful — including medication, medical, legal or financial deadlines.

4. Acceptable use

Use the App lawfully. Do not use it to store unlawful content, and do not attempt to circumvent purchase verification or the free-version limits.

5. Maintenance and support

We are solely responsible for any maintenance and support for the App. Apple has no obligation whatsoever to furnish any maintenance or support services. Support is provided on a best-effort basis at candanweng@gmail.com; see the support page.

6. Warranty

The App is provided “as is” and “as available”, without warranty of any kind to the fullest extent permitted by law.

In the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the App to you. To the maximum extent permitted by applicable law, Apple has no other warranty obligation whatsoever with respect to the App. Any other claims, losses, liabilities, damages, costs or expenses attributable to a failure to conform to any warranty are our sole responsibility.

Nothing in this Agreement excludes rights you have under mandatory consumer protection law in your country, which are not affected.

7. Limitation of liability

To the extent permitted by law, we are not liable for indirect, incidental or consequential loss, or for loss of data, arising from your use of the App. Where liability cannot be excluded, our total liability is limited to the amount you paid for the App in the twelve months before the claim.

8. Product claims

We, not Apple, are responsible for addressing any claims by you or a third party relating to the App or your possession and use of it, including: (i) product liability claims; (ii) any claim that the App fails to conform to an applicable legal or regulatory requirement; and (iii) claims arising under consumer protection, privacy or similar legislation, including in connection with the App’s use of HealthKit or HomeKit frameworks, if applicable.

9. Intellectual property

If a third party claims that the App or your possession and use of it infringes that party’s intellectual property rights, we, not Apple, are solely responsible for the investigation, defence, settlement and discharge of that claim.

The App, its name and its design remain our property. This Agreement transfers no ownership.

10. Legal compliance

You represent and warrant that (i) you are not located in a country subject to a U.S. Government embargo, or that has been designated by the U.S. Government as a “terrorist supporting” country; and (ii) you are not listed on any U.S. Government list of prohibited or restricted parties.

11. Third-party terms

You must comply with applicable third-party terms of agreement when using the App — including, where relevant, the Apple Media Services Terms and Conditions.

12. Third-party beneficiary

Apple and its subsidiaries are third-party beneficiaries of this Agreement, and upon your acceptance of it, Apple has the right (and is deemed to have accepted the right) to enforce this Agreement against you as a third-party beneficiary of it.

13. Termination

This licence ends if you stop using and delete the App, or if you materially breach this Agreement. Sections 6 to 9 and 12 survive termination.

14. Changes

We may update this Agreement. The current version is always published here with its date, and material changes will be noted in the App’s release notes. Continuing to use the App after a change means you accept the updated terms.

15. Governing law

This Agreement is governed by the laws of Taiwan (Republic of China), without regard to its conflict-of-laws rules, save where mandatory consumer protection law in your country of residence provides otherwise.

Frequently asked

What makes Rhythms different from other habit apps?

Most apps schedule by the calendar: “every Sunday”. Rhythms can also schedule by how long it has actually been: “seven days after I last did it”. If you meant to change the sheets on Sunday and got to it on Wednesday, a calendar app pushes you back to Sunday — four days later. Rhythms starts the seven days from Wednesday, which is what you actually wanted.

A task shows a strikethrough. Why?

It was completed today and the new cycle it earned has not come due yet. Once it comes due again — or the day rolls over — it returns to the list normally.

I completed something by mistake

Tap Undo on the message that appears at the bottom. That puts the task’s schedule and its history back exactly as they were. Only the most recent completion can be undone.

Reminders never arrive

Notifications are probably switched off for Rhythms. Open Settings › Notifications › Rhythms and allow them, or use the “Reminders are off” banner at the top of the task list, which links straight there.

Where are my tasks stored? Is there sync?

On your device only. There is no account and no cloud sync in this version. Use Settings › Backup › Export a backup to keep a copy — that file is the only thing that survives losing or replacing the phone.

I bought Pro but a new phone shows the free version

Settings › Restore purchases, signed in with the same Apple Account that made the purchase. Restoring brings back Pro; it does not bring back your tasks — for those you need a backup file.

Why is my task no longer in Today?

Tasks overdue by more than three of their own cycles (at least a day) move out of Today so they stop crowding it, and a line at the top says how many. Tap it to see them under Overdue. Nothing has been deleted.

What does a tip do?

Nothing, deliberately. Tips are a thank you and unlock no features — Pro already covers those. Tipping is entirely optional.

Rhythms Pro

Pro removes the limit on how many tasks you can keep and adds backup and restore. There are three ways to get it, and they unlock exactly the same features:

PurchaseLengthPrice
Rhythms ProOne-off, permanentUS$19.99
Rhythms Pro (Yearly)1 year, auto-renewingUS$9.99 per year
Rhythms Pro (Monthly)1 month, auto-renewingUS$0.99 per month

Prices are shown in your own currency inside the app and may differ by region; the amount on the App Store confirmation screen is the one that is charged.

Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically for the same period unless auto-renew is turned off at least 24 hours before the end of the current period; your account is charged for renewal within 24 hours before the period ends. The one-off purchase never expires and never renews.

Use of Rhythms is governed by our Terms of Use (EULA).

How do I manage or cancel a subscription?

Settings › Apple Account › Subscriptions on your device, where you can turn off auto-renew at any time. Subscriptions are managed by Apple; we cannot cancel or refund them on your behalf. Refund requests go through reportaproblem.apple.com.
