Terms of Use

Updated

Last updated: October 15, 2026

These Terms govern your use of BookNotion (including the Z plan), the BookNotion iOS app, the BookNotion browser extensions and the websites booknotion.site and z.booknotion.site (the "Service"), provided by Blue Office Inc., 2F Ginza Otake Residence, 1-22-11 Ginza, Chuo-ku, Tokyo 104-0061, Japan ("Blue Office", "we", "us"). By creating an account or using the Service, you agree to these Terms and to our Privacy Policy.

1. The Service

BookNotion imports your Kindle highlights and other highlights you choose, saves them to your Notion workspace, and sends you reminders of what you have read. Some features require a paid plan (the Z plan).

BookNotion is not affiliated with, endorsed by or sponsored by Amazon or Notion. Kindle is a trademark of Amazon.com, Inc. or its affiliates; Notion is a trademark of Notion Labs, Inc.

2. Your account

You must be at least 16 years old (or the age of digital consent where you live) to use the Service. Keep your login details secure; you are responsible for activity under your account. Give us accurate information, including a valid email address.

3. Your content

Your highlights, notes and other content remain yours. You give us a limited license to store, process and copy your content only as needed to provide the Service, including writing it to Notion and including it in reminders, and to create aggregated statistics as described in our Privacy Policy. You are responsible for making sure you have the right to save the content you import, and for using it in line with the terms of Amazon, Notion and other services you connect.

4. Subscriptions, free trials and payment

  • Plans and prices are shown before you buy. Prices include applicable taxes unless stated otherwise.
  • Free trial. New Z plan subscriptions may start with a free trial (usually 7 days, or longer with a partner code or referral link). Unless you cancel before the trial ends, your subscription starts automatically and you will be charged.
  • Automatic renewal. Subscriptions renew automatically at the end of each billing period (monthly or yearly) at the then-current price until you cancel. We will give you advance notice of any price increase.
  • Where you buy matters.
    • In the iOS app: purchases are made through Apple's App Store and are governed by Apple's terms. Manage or cancel them in your Apple ID settings. Refunds are handled by Apple.
    • On the web in Japanese yen: payments are processed by Stripe on our behalf.
    • On the web in US dollars: Link, Stripe's consumer service, sells the subscription to you as reseller and merchant of record. Link's terms of sale apply in addition to these Terms, and Link handles taxes, payments and refunds for that purchase.
  • Cancellation. You can cancel at any time from the plan settings on z.booknotion.site (or in your Apple ID settings for App Store purchases). Cancellation takes effect at the end of the current billing period, and you keep access until then.
  • Refunds. Except where required by law or stated otherwise by the seller (Apple or Link), payments are non-refundable and we do not provide refunds for partial periods. If something is wrong with your charge, contact us and we will look into it.
  • Right of withdrawal (EEA, UK and similar laws). If you are a consumer with a statutory right to withdraw from a purchase, you may have the right to withdraw within 14 days. Because the Service starts immediately, by starting a paid subscription you request immediate performance and acknowledge that you may lose this right once the Service has been fully provided, to the extent allowed by law. Nothing in these Terms limits rights you have under mandatory consumer protection law.

5. Acceptable use

Do not: overload or interfere with the Service; access it by automated means other than the features we provide; reverse engineer it except as allowed by law; resell or provide it to others as a commercial service; use another person's account; or use it to infringe anyone's rights or break the law.

6. Third-party services

The Service works with services we do not control, including Amazon Kindle, Notion, Apple and Google. Changes to those services may affect or interrupt BookNotion, for example if Amazon changes its notebook pages. Your use of those services is governed by their own terms.

7. Changes and availability

We may change, add or remove features. We may suspend the Service temporarily for maintenance or for reasons outside our control. If we discontinue a paid feature or the Service, we will give you at least 30 days' notice where possible and refund any prepaid amount for the period after it ends.

8. Suspension and termination

You may stop using the Service and delete your account at any time. We may suspend or close your account if you seriously or repeatedly break these Terms, or if required by law; where reasonable, we will tell you why first.

9. Intellectual property

The Service, including its software, design and our trademarks, belongs to Blue Office or its licensors. These Terms do not give you any rights to them other than the right to use the Service.

10. Disclaimers

The Service is provided "as is". We work hard to keep imports and syncing accurate and reliable, but we do not guarantee that the Service will be uninterrupted or error-free, or that every highlight will be imported. Keep your own copies of important content.

11. Limitation of liability

To the extent permitted by law, Blue Office is not liable for indirect or consequential damages, or for loss of data or profits, and our total liability for any claim relating to the Service is limited to the amount you paid us in the 12 months before the claim. These limits do not apply to liability that cannot be limited by law, including liability for our intentional misconduct or gross negligence.

12. Changes to these Terms

We may update these Terms. If a change is material, we will notify you by email or in the Service at least 30 days before it takes effect. If you continue to use the Service after that, the updated Terms apply; if you do not agree, you can cancel before the change takes effect.

13. Governing law and disputes

These Terms are governed by the laws of Japan, and the Tokyo District Court has exclusive jurisdiction in the first instance. If you are a consumer, you also keep the protection of the mandatory laws of the country where you live and may bring a claim in its courts.
