Privacy policy

This is an English translation. If there is any difference in meaning, the Japanese version prevails.

TypingStep ("the Site") is run on the principle of collecting as little personal information as possible. This policy explains what information the Site handles and why.

1. Without logging in

Your practice records (stars, speed and accuracy for each lesson, and your weak keys) are stored only in your browser (localStorage) and are not sent to the Site's server.

2. When you log in

You can log in with an account from an external service such as Google. When you log in, the Site receives and stores only the following:

• The user ID issued by the external service: the original value is not stored. It is converted into a form that cannot be reversed (a hash) and is used only to recognize you when you log in again with the same account.
• Your practice records: stars, speed, accuracy and date for each lesson, and a summary of your weak keys, so that you can continue practicing on other devices.
• The date your account was created and the date of your last login

We do not collect or store your email address, name or profile picture (Google login requests only an ID that identifies you).

3. Cookies

• A cookie that keeps you logged in (up to 30 days)
• A temporary cookie used for security checks during login (10 minutes)
• A cookie that remembers the display language you chose (up to 1 year)

We do not use cookies for advertising or analytics.

4. Sharing with third parties

We do not share stored information with third parties, except where required by law.

5. Deleting your data

You can delete all information stored on the server at any time with "Delete account" on My page. Deleted data cannot be restored.

6. Contact Us

If you have any questions about this policy, please use our contact page.

7. Changes

We may revise this policy as needed. Important changes will be announced on the Site.
