Privacy Policy
Last updated: 2026-08-29
1. The short version
Your files and your data stay on your device. The free tiers of our products (Shikibu, Subtitle Toolkit, KitchenOS) process everything locally and never upload your documents, subtitles, or kitchen data to our servers. The only data we collect is what's needed to run the paid services (account, purchase, and subscription records).
2. What each product does with your data
- Subtitle Toolkit (free + Pro): all SRT and video processing happens in your browser. Files never leave your device. The Pro purchase is recorded via our payment processor.
- KitchenOS (free desktop): offline-first; recipes, inventory, and orders live in a local database on your machine. Premium adds cloud sync of kitchen data you explicitly push.
- Shikibu: EPUB editing happens locally. Pro includes a bundled offline dictionary; no reading data is sent to us.
- Lingua Mundi API: lookup requests are processed by the API. Usage is associated with your account for rate limiting and billing.
3. Accounts and payments
Accounts are provided by Clerk (identity provider) and purchases are processed by Stripe. We store only what our own services need: your account identifier, what you purchased, and subscription status. We never see or store your full card number — payments are handled by Stripe under their own privacy policy.
4. What we do NOT collect
- We do not sell or rent personal data.
- We do not use advertising trackers or cross-site ad networks.
- We do not read your documents, subtitles, EPUBs, or kitchen data.
5. Cookies and local storage
The apps use local browser storage to remember your language preference and (where applicable) your sign-in session. No third-party advertising cookies are used.
6. Data retention and deletion
You can delete your account at any time from the product dashboard, which removes your account and associated records. Local app data is deleted when you remove the app's data folder or uninstall.
