Data Sent to Developers

A transparent explanation of what data yomito collects and sends to developers.

Summary

By default, no data is sent to yomito developers. The only data that may reach our servers is Crash Reports, and even those require your permission. Everything else stays safely on your phone.

Crash Reports

Crash report submission is optional and disabled by default. You will be asked whether you want to enable it when you first open the app, and you can change this choice at any time.

What IS sent

• Stack traces — technical code details of what caused the app to crash or force-close.
• The Android version you're using.
• Your phone brand and model (Manufacturer).
• The installed yomito app version number.
• App release type (debug, release, or nightly).

What is NOT sent

• Your name, email, or personal identity.
• Reading history or comic lists.
• Usernames, passwords, or account credentials.
• Downloaded comics or other media files.
• Favorites, bookmarks, or reading statistics.
• Search history.
• Device IDs (IMEI, Android ID, Advertising ID).
• Location / GPS data.
• Behavioral tracking data (user habits).

Where does error data go?

Crash reports are sent to Sentry.io, a secure third-party crash reporting service encrypted via HTTPS. Only yomito developers can access this data to fix bugs. Reports are stored for approximately 90 days, then automatically deleted.

How to enable / disable

Go to Settings -> Services -> Send crash reports to toggle it on or off whenever you want.

Synchronization Data

If you enable the Synchronization feature and connect to a sync server, your selected data (reading history, favorites, bookmarks) will be sent to that server. yomito does not operate an official sync server — you must choose or host your own server.

Note

You are responsible for the privacy policy of the sync server you use. yomito developers do not receive your sync data, unless you use a server specifically created by our developers.

Data that NEVER leaves your phone

All data below is purely stored in your phone's local storage and is never sent to yomito developers:

• Reading history and chapter progress.
• Favorites list and bookmarks.
• Downloaded comic image files.
• Reading statistics and time tracked.
• App settings and appearance customizations.
• Comic title search history.
• Image cache and parser data.
• Cookies from comic source websites.

Data sent to Third-Party Services (Not yomito)

Some optional features will send data directly to third-party services, not to yomito:

Service	Data Sent	Your Control
Comic source websites (Kaguya, Mangadex, etc.)	Comic title search keywords, your IP address.	You choose which sites to enable.
Tracker services (MyAnimeList, AniList, Shikimori)	Chapters read progress, ratings.	Optional; you can disconnect at any time.
Discord	Comic title / chapter being read (for Rich Presence status).	Optional; you can disconnect at any time.

Note

The services above are not controlled by yomito. Please review the privacy policy of each service before connecting.

What we do NOT do

• NO Google Analytics or similar third-party analytics trackers.
• NO tracking of what comics you read.
• NO behavioral profiling or user activity monitoring.
• NO ad networks (AdMob, Facebook Pixel, pop-up ads, etc.).
• NO location tracking.
• NO selling or monetizing user data.

Transparency

yomito is a 100% open-source project. You can directly view the source code that manages data collection and error reporting at github.com/zannbjir/toto. Community members actively review our code to ensure these privacy claims are accurate.

You're in Control

Settings -> Services

• Enable or disable automatic error reports.
• Connect or disconnect tracker service accounts.
• Configure sync server connections.
• Revoke third-party authorizations.

Privacy FAQ

Does yomito track what comics I read?

No. Your reading history is only stored on your phone, unless you enable the Synchronization feature to a server of your choice.

Who can see crash reports?

Only yomito developers, through the Sentry.io dashboard. No outside parties or other companies have access to this data.

What if I don't want to send any data at all?

Simply disable the crash report option in Settings -> Services -> Send crash reports. The app works 100% normally without sending a single byte of data to yomito.

Is my data encrypted?

Yes. Crash reports are sent over a secure connection (HTTPS). Local comic data is also stored in an internal phone database secured by the Android system.
