Month to Month Privacy Policy

Version 1.2 · Effective date: November 1, 2026

This is a translation. If it differs from the Korean version, the Korean version prevails.

Change history: 1.2 (2026-11-01) Section 1: your logs are not included in the account backup that comes back after you delete and reinstall the app. 1.1 (2026-10-31) Added the English version, with sections on data stored outside your country and Do Not Track. The content follows the Korean version 1.1 (effective October 13, 2026).

1. Your logs are stored only on this device

The period logs, symptoms, mood, notes, and usual cycle length you enter in Month to Month are stored only on your phone. They are not sent to us, the operator. We cannot receive or see them.

• If you have your phone's own backup or device transfer turned on, the app's data may be included in that backup, depending on your device settings. Your logs are not included in the account backup that comes back when you delete and reinstall the app. Deleting the app deletes the logs on your device. This is a function of your device's operating system. Month to Month does not upload your logs to any other storage on its own.
• A file made with "Create backup file" is encrypted with a password you choose. We do not know the password and cannot open the file. The file is saved to a place you choose, such as a messenger, a files app, or a drive.
• A file made with "Export as CSV" is not encrypted. Check where you save or send it.
• If you turn on "Fertile window reference" in Settings, the range is calculated on this device only from the period logs already stored here. It is shown on screen and is not saved separately or sent to us. The on/off setting is also stored only on this device.

2. Information we process

Error information does not include the contents of your logs (dates, flow, symptoms, mood, notes), your email address, or your IP address. If you turn off Settings > "Send error reports", nothing is sent. We keep error information on a server that we operate ourselves in South Korea.

Month to Month has no sign-up. We do not collect your name, email address, age, location, contact details, or device identifiers. We do not collect app usage statistics.

3. Permissions (all optional)

• Notifications: The app asks only when you turn on reminders for the estimated date. You can use the app without allowing them.
• Face ID and fingerprint: Used only to unlock the app lock with biometrics. Your biometric data never leaves your device.

4. How to delete your data

• Tap Settings > "Delete all logs" to delete the logs on this device.
• Uninstalling the app also deletes the logs on your device. Backup files you already made and your phone's backups remain where you saved them. Please delete them there yourself.

5. Children under 14

Because there is no sign-up or data collection, the app does not ask your age.

6. Do Not Track

Month to Month does not respond to Do Not Track (DNT) browser signals. We do not track you across other companies' apps or websites.

7. Changes to this policy

We post the updated policy in the app and at https://dalmada.hyunjins.co.kr/legal/privacy_en.html and update the effective date. For important changes, we notify you in the app.

8. Data stored outside your country

The only information we send to a server is error information, and only if you leave "Send error reports" on. It is sent to and stored on a server in the Republic of Korea (South Korea). If you live outside Korea, this information is transferred to Korea. By agreeing to this policy and the Terms of Use, which you do when you start using the app, you consent to this transfer.

• Information transferred: error type and where it happened, app version, OS and device model. It does not include your logs, email address, or IP address.
• Where it is stored: a server in South Korea that we operate ourselves.
• Retention: 90 days.
• How to stop it: turn off Settings > "Send error reports". Everything else in the app keeps working.

Korean privacy law: Korea has the Personal Information Protection Act. The Personal Information Protection Commission (PIPC) supervises it. Japan's Personal Information Protection Commission publishes a report on the Korean system: https://www.ppc.go.jp/files/pdf/korea_report.pdf

How we protect your data:

• Your logs never leave your device, so we cannot access them.
• Error information is stored on a server we operate ourselves, and only we can access it.
• Error information does not include your logs, email address, or IP address.
