This policy covers how personal information is handled in yodaka (“the app”), provided by KnotsLab LLC (“we”).
What we do not collect
The app collects nothing that identifies you.
- There are no accounts. We never ask for your name, email address, or phone number
- The app contains no advertising or analytics code, so nothing goes to a third-party service
- We do not ask for access to your location, contacts, photos, camera, or microphone
- We do not serve ads
What stays on your device
As you read, the app stores the following on your device.
- Passages, works, and writers you have liked
- Markers and notes
- Bookmarks (where you stopped)
- Reading records (time, characters, dates)
- Lists you made
- Display settings (typeface, theme, text size, and so on)
None of it is sent to our servers. Deleting the app deletes it from the device.
What goes to iCloud
Turn on iCloud sync and your markers, notes, likes, bookmarks, reading records, lists, and book colours are stored through Apple’s CloudKit in your own iCloud private database, shared between devices signed in to the same Apple Account.
That is your iCloud, not our server, and we cannot read it. Apple’s privacy policy governs data held in iCloud.
Turn sync off and no further changes are sent. To remove what is already there, delete the app’s iCloud data in iOS Settings.
To receive sync changes, the app registers for remote notifications. These are the silent notifications CloudKit uses: nothing is displayed, and you are never asked for notification permission.
When the app connects
The app makes network requests in these cases.
- Fetching texts, indexes, writer information, and dictionaries from our delivery server (
content.yodaka.app) - Downloading a font (retrieved from Apple’s servers)
- Buying or restoring a purchase through the App Store (handled by Apple)
None of these send anything that identifies you. Our delivery server keeps access logs — source IP address, timestamp, and the file requested — as any web server does. We keep them to run the service reliably and to prevent abuse, and we do not use them to identify individuals.
Purchases
yodaka Premium is bought and restored through the App Store, and Apple handles it.We never receive card numbers or other payment details. To check whether you own it, the app reads a receipt Apple has signed, on the device.
Links to other sites
Links to sources (Aozora Bunko, Project Gutenberg), dictionary attributions, and our own contact page take you to other sites. What happens there is governed by their own policies.
Children
The app carries age ratings that reflect the content of the works it holds. It collects nothing that identifies anyone, at any age.
Changes
If this policy changes, we update this page and the date at the top.
