Red Sheet Privacy Policy

1. What this policy covers

This policy covers the Red Sheet app for iPhone and iPad (赤シート in Japanese), and any email you send us for support. Red Sheet turns photos, scans and PDFs of your own textbooks, workbooks and notes into pages. It hides the answers you wrote in colored pen or under markers, the way a red, green or blue plastic sheet does. It also helps you study, with ○ / × grading and spaced review. Red Sheet is provided by WGroup (“we”, “us”). It needs iOS or iPadOS 17 or later, and it works in Japanese and English.

2. What we receive, and what we don’t

Your pages never reach us. We never receive your pages, edits, grades, review schedule, Notebooks, Subjects or settings. Red Sheet creates no account, and there is no server of ours to send anything to. The app itself has no analytics.

The app goes online only to reach Apple’s iCloud, if you turn on iCloud Sync (section 5).

We receive only what you send us by email (section 11).

3. What is stored on your device

What you make with Red Sheet is stored in the app’s own storage on your iPhone or iPad:

• your pages (the original images);
• your edits: boxes, eraser marks, marker strokes and Always Show;
• your grades and your review schedule;
• your Notebooks and Subjects;
• your settings.

Hiding runs on your device, without the internet. None of this is sent to us. Your iPhone’s or iPad’s own iCloud Backup, or a backup to a computer, also includes this app’s data, as it does for any app.

4. Camera, photos and files

Camera. Red Sheet uses the camera only while you scan a page (with the iOS document scanner) and while you use Live, which puts a sheet over the camera image. Camera frames are processed on your device and are not stored. Only a page you capture, with the scanner or Live’s shutter button, is saved, on your device. The app asks for camera access once, with the iOS prompt. You can change your answer at any time in the Settings app on your iPhone or iPad.

Photos. You choose photos in the iOS photo picker. The app receives only the photos you pick. It never asks for access to your photos.

Files. You can choose PDFs and images in the Files app.

5. iCloud Sync

iCloud Sync stays off until you turn it on, on each device, in Settings › iCloud Sync. When it is on, your pages, edits and grades are also stored in your own private iCloud database (Apple’s CloudKit). Other people can’t see it, and neither can we. Apple handles it under the Apple Privacy Policy. To sync, your devices must use the same Apple Account.

6. Ads

The app shows no ads. Google’s ads software (Google Mobile Ads) is included for a later version, but the app never starts it, so it requests no ads and sends nothing to Google. If the app ever shows ads, we will change this policy first and say so here.

7. Purchases

The app has no in-app purchase. Everything is free: capturing pages, hiding, all three sheets (red, green and blue), bands, revealing answers, the Edit tools (Box, Eraser, Marker), Live, PDF import, ○ / × grading, Review (spaced repetition and stats such as Mastery), iCloud Sync, and backup and restore. There is no page limit.

8. Backup and restore

Backup is free for everyone. In Settings › Backup, Export Backup puts everything in your Library into one .zip file and opens the iOS share menu, where you choose where it goes (the Files app, AirDrop and so on). The file holds every Notebook, each page’s original image, your edits and your grades. The app does not encrypt it. Once you save it somewhere else, that place’s terms apply.

Restore from Backup reads a .zip file you pick in the Files app. It adds what’s missing and never overwrites newer data.

If your last backup is more than 30 days old, the app may show a reminder on the Library. It is not a notification, and it needs no permission.

9. Children

Red Sheet is made for students, including minors. It has no account, collects nothing itself and shows no ads. Parents and guardians can send any question to wecanmakeit.vn@gmail.com.

10. Deleting your data

• Everything on your device: delete the app. Everything it stored on the device is removed.
• Your copy in iCloud: if iCloud Sync was on, delete it in the Settings app on your iPhone or iPad: Settings › [your name] › iCloud › Manage Storage.
• Backups you exported: they are your own files. Delete them where you saved them.

We hold none of your pages, so there is nothing for us to delete, except support emails (section 11).

11. When you contact us

If you email us, we receive your email address, your name if your email shows it, and what you write or attach. We use it only to reply to you, and we delete it when it is no longer needed.

12. For users in Japan (Act on the Protection of Personal Information)

• The app never sends your pages, edits, grades or settings to us. We do not receive or handle them.
• If you turn on iCloud Sync, your data is stored in your own iCloud and handled under Apple’s privacy policy. We cannot see it.
• The only personal information we may hold is what you send us by email (section 11). Purpose of use: replying to you.
• Support emails are stored with our email provider, Gmail (Google LLC, USA), whose servers may be outside Japan. Security measures: access to the support mailbox is limited to the people who answer it and protected with two-factor authentication, and emails are deleted once they are no longer needed.
• We do not give personal information to anyone else without your consent, except as the law permits.
• To ask us to disclose, correct, stop using or delete the personal information we hold about you, or to make a complaint, email wecanmakeit.vn@gmail.com.
• Operator: WGroup. If you ask, we will tell you our address and the name of our representative without delay.

13. Changes to this policy

If this policy changes, we will post the new version on this page with a new date.
