Privacy Policy
Last updated: October 7, 2026
Yoakashi is a reader for the comics and manga you bring. This page lists what the app keeps on your device, what it sends and to whom, and why. Yoakashi shows no ads, runs no tracking, and we never sell your data.
On your device
- The comics and manga you import, the servers you connect, your reading progress, chapters you download for offline reading, and your settings live in the app’s own storage on your iPhone, iPad, or Mac.
When you sign in with an Epiphani account
- Signing in is optional. When you sign in, Epiphani Studios stores your library list (series, covers, reading status and position, categories, reading mode) and your reading progress with your account, so every device you sign in on stays in step.
- Signing out on a device stops it syncing. To have your account’s library data deleted, email us at the address below.
Downloads and iCloud
- Chapters you download are shared with your other devices through your own iCloud (Apple’s iCloud Drive), governed by Apple’s Privacy Policy.
New-chapter alerts
- When you turn on notifications, the server your series are read from keeps the list of series you follow, which ones you want alerts for, and your device’s Apple push token, so it can tell you when a new chapter appears. The alert text names the series and the chapter.
Feedback and diagnostics
- When you send feedback, the report carries your message, a picture of the app window, the app and iOS versions, and your device model.
- If the app closed unexpectedly, a diagnostics report (recent app activity, device state, and a random install identifier) is sent the next time you open it, so we can fix the cause. The install identifier is created by the app and is not your Apple ID.
- Crash summaries from iOS (the kind of crash and the app version) are included in the diagnostics the app sends.
Series details from public catalogs
- To show release schedules and to match a series across catalogs, the app sends the series title to MangaUpdates and MangaDex. Only the title is sent.
Servers you connect
If you connect your own Komga, OPDS, or Suwayomi server, Yoakashi talks to that server directly with the address and credentials you provide, to show you your library. Those credentials are stored on your device.
Children’s privacy
Yoakashi is not directed to children under 13. The content in Yoakashi is whatever you import or host yourself, so please use the App Store age rating as your guide for suitability.
Changes to this policy
If this policy changes, the updated version will be posted on this page with a new “last updated” date.
