Upgrade Steps

There are two ways to start a paid plan.

1 Log in to Reading Forest

First, log in to Reading Forest. The Login Guide explains how, with screenshots.

2 Open the Pricing page

Open the Pricing page.

From inside Reading Forest, you can also open Settings from the menu (File → Settings), go to the "Plan" tab, and click "Pricing".

3 Choose: free trial or subscribe

In the box for the plan you want, click one of the following.

The Personal Plan box on the Pricing page, with the Start 30-Day Free Trial button and the Subscribe without trial link below it outlined in red

  • "Start 30-Day Free Trial": your trial starts right away. No card entry screen appears. After the message "Your 30-day free trial has started!", you return to Reading Forest. If you are trying it free, you are done.
  • "Subscribe without trial": takes you to the checkout page in step 4. If you have already used your trial, the button reads "Subscribe" instead and also takes you to step 4.

When you subscribe to the Group plan, enter the number of users (2–100, including yourself) and check the monthly price shown before you continue.

4 Enter your payment details on the checkout page

You are taken to the checkout page of Stripe, our payment provider. The plan and price are on the left; the payment form is on the right.

Fill in the following. The email field already shows the address you registered with Reading Forest.

  • Card number (JCB, Visa, Mastercard, American Express, Diners Club, Discover)
  • Expiration date (MM/YY) and security code (CVC)
  • Cardholder name
  • Country or region

The plan is priced in Japanese yen (¥380 per month for the Personal plan). Depending on where you are, Stripe may also show the price in your local currency, as in Figure 2; you can choose JPY there. Depending on your device and browser, buttons for Apple Pay and similar services may appear at the top. If you have a promotion code, enter it with "Add promotion code" on the left.

Secure Payment

Your payment information is processed by Stripe's secure payment system. Card information is encrypted and is not stored on our servers.

5 Press "Subscribe"

Check the details and click "Subscribe".

Billing starts on the day you subscribe

Subscribing this way has no trial period. You are charged for the first month on the day you subscribe ("Total due today" on the checkout page), and then automatically every month until you cancel. To cancel, see How to Cancel Your Paid Plan.

When payment is complete, a confirmation page appears; click the button on that page to return to Reading Forest, where all paid features are now available.

Upgrade Complete!

You can now use all the features of your paid plan. Enjoy Reading Forest!

What You Can Do After Upgrading

Unlimited Books (Works) per File

While the free plan limits you to 20 books (works) per file, paid plans let you add unlimited books (works) to a single file. Manage all your reading history in one place without splitting files.

Detailed Notes & Quotes

Save memorable phrases and important content as notes for each book. Search and revisit them anytime.

Data Export

Export your reading records in Excel / CSV / Markdown / HTML / BibTeX formats. Great for integration with other tools or data backup.

Share with Family & Teams (Group Plan)

Share reading records with family members or team members. Recommend books to each other or prepare for book clubs.

Frequently Asked Questions
