How We Handle Personal Data
Fuji Bit Inc. ("we") handles the information collected by the mobile app "Procedure Manuals Are Novels" (the "App") in compliance with applicable data protection laws, as described below. This page organizes the contents of our Privacy Policy by type of information.
The App does not collect your name, email address, phone number, postal address, precise (GPS) location, contacts, or photos. There is no account registration.

2. Sharing with Third Parties

4. How to Stop Data Collection
- Personalized ads: choose "Don't allow" on the "About ads" screen shown on first launch and you will not see interest-based ads (non-personalized ads are still shown). You can change this later in "Ad settings" in Settings.
- Tracking (iOS): choose "Ask App Not to Track" in the dialog shown on first launch and the IDFA will not be used. You can change this later in Settings > Privacy & Security > Tracking.
- Advertising ID (Android): reset or delete it in Settings > Privacy > Ads (or Settings > Google > Ads, depending on the device).
- Votes: no vote data is sent unless you vote. You can delete your rating at any time with the "Clear" button on the rating sheet.
- Everything: once you uninstall the App, nothing more is sent.
5. Requests for Access or Deletion
To request access to or deletion of your vote data stored in Cloud Firestore, contact us at the address below. Because the App has no accounts, we may ask for the maxim numbers you voted on and the approximate dates of your votes to identify your data. For information collected by Pangle, please contact Pangle via its privacy policy above.
6. Security
Firebase security rules limit access to vote data: you can read and write only your own votes, and everyone can read only the aggregate scores. App Check blocks access from anything other than the genuine App.
