Privacy Policy
What we collect
- Account: username, an optional email address, and a salted password hash (we never store your password itself); your native language and daily goal.
- Sign-in records: IP address, browser user agent and times of sign-in, used for security.
- Reading data: books and versions you read, progress, words you look up, and anonymous reading metrics used to adjust difficulty.
- Texts you import and the versions generated from them.
- Payments: handled by Creem. We receive an order ID, the pack you bought, the amount and status — never your card details.
- Visit statistics: anonymous page-view counts without tracking cookies. Your IP address is used only in memory to look up your country (with a local copy of the DB-IP database) and to count unique visitors per day: we store the country code and a one-way hash of the IP made with a random key that is replaced every day, never the IP itself. Statistics are deleted after 90 days.
How we use it
To run the Service: generating glosses and translations, keeping your shelf and vocabulary in sync across devices, granting and charging tokens, preventing abuse, and improving reading difficulty. We do not sell personal data and do not show ads.
Who processes it
- Our servers are hosted by Alibaba Cloud in Japan.
- Text you read or import is sent to AI model providers (currently DeepSeek and Zhipu GLM) to generate glosses and translations, or to the provider you configure with your own API key.
- Payments are processed by Creem (Merchant of Record) and its payment partners.
Your browser
We store your sign-in token, settings, your own API key (if you add one) and local reading data in your browser’s local storage. Clearing site data removes them.
Retention and your rights
We keep account data while your account exists. You can ask us to export or delete your account and data by emailing the address below; we reply within 30 days. Payment records are kept as long as tax and accounting rules require.
