Privacy Policy
Each app handles different data. Each app’s own policy comes before this common policy.
This policy explains how SR (“we”) handles personal information in apps published as SR Labs Korea. App-specific details are listed in section 6.
1. What we handle and why
| Data | Purpose | Retention |
|---|---|---|
| Content you create (notes, ink, attachments, etc.) | Provide app features | See each app’s policy |
| Account details used to sign in or connect (email, Google account identifier, etc.) | Sign-in and Drive connection | See each app’s policy |
| Purchase records | Unlock and restore paid features | Processed by Google Play. We never receive card details |
| Crash reports and usage statistics | Improve quality | Only with your consent; deleted once no longer needed |
| Access logs (IP, time, device info — apps with a server only) | Security and troubleshooting | Recorded automatically, deleted periodically |
2. Sharing
We do not sell personal information or share it for advertising. Our apps contain no ads. Payments are processed by Google Play, Google sign-in by Google, and, if you choose, storage by Google Drive; their privacy policies also apply. Mnote downloads its handwriting model through Google ML Kit and recognizes ink on your device; Google may receive feature-usage and diagnostics data in the process.
3. Your choices
- You can delete your data, disconnect Drive, or withdraw diagnostics consent in the app settings at any time.
- Use “Delete account & data” in the app (“탈퇴” in Dalbit Saju), or contact us below to request deletion without using the app.
4. Security
All connections use HTTPS. How data is stored differs by app: Dalbit Saju encrypts birth dates and times with AES-256 on our server, and Mnote encrypts notes on your device before uploading them to Google Drive (only you hold the recovery key; if it is lost, we cannot recover your data). See each app’s policy for details.
5. Children
Our apps are not directed to children under 14.
6. App-specific details
Dalbit Saju
- Information needed for sign-up and chart calculation is stored on our servers — see saju.ssrr.app/privacy
- Birth dates and times are stored encrypted and deleted as soon as you delete your account.
Mnote
- Notes are stored only where you choose: on device, in your Google Drive (hidden app folder), or on a server you run.
- Notes sent to Google Drive are encrypted on your device first. Home-server mode is not end-to-end encrypted, so that server’s operator can read them. Either way, notes never pass through our servers.
- The only Google permission requested is the app folder scope (
drive.appdata); we cannot read your other Drive files.
