Privacy Policy

Effective date: November 15, 2026

This is an English translation of the Korean original. If the two differ, the Korean version prevails.

Information we collect

• Push subscription details: the push address (endpoint) and encryption keys issued by your browser, and your browser type (User-Agent)
• Reminder content: title, note, notification time, and repeat rule (including start and end dates). Titles and notes are stored encrypted with AES-256-GCM.
• Google account information (only if you sign in): your email address, name, and Google account ID. We never receive your Google password.
• Session information: a session cookie (a random value) that remembers your sign-in status and this browser’s reminders. Our server stores only a hash of this value.
• Delivery history: when each notification was sent, the push service’s response code, and whether it was marked done or snoozed
• Access logs: request records generated automatically while the server is running
• Analytics: information that Google Tag Manager and Google Analytics collect through cookies, such as the pages you visit, when you visit, the page that referred you, your browser and device type, and your approximate location (see “Analytics tools” below)

If you don’t sign in, we don’t collect anything that can identify you, such as your name, email address, or phone number — each browser is identified only by a random session. If you sign in with Google, we use the Google account information above only to sign you in and to store your reminders in your account.

How we use your information

We use reminder information only to send web push notifications at the times you set, to process done and snooze actions, and to show delivery status. We use analytics data only to understand how the site is used and to improve the service.

Retention and deletion

• Clicking “Delete all data from this browser” at the bottom of the main page (“Delete my account and data” when you’re signed in) deletes your data immediately.
• Session cookies expire after 180 days without use and are deleted immediately when you sign out.
• Reminders and account information are deleted automatically after 180 days without any visits or activity.
• Delivery history is deleted after 90 days.

Sharing with third parties

To deliver notifications, encrypted notification content passes through your browser maker’s push service (Google FCM, Mozilla, Apple, etc.). Analytics data is collected and processed by Google (see below). We don’t share your information with any other third parties.

Analytics tools

To understand how the site is used, we use Google’s analytics tools, including Google Tag Manager and Google Analytics.

• These tools use cookies and similar technologies to collect information such as the pages you visit, when you visit, the page that referred you, your browser and device type, and your approximate location. We don’t send information that directly identifies you, such as your name or email address, and we never send reminder titles or notes.
• The collected information is processed by Google and may be stored on servers in other countries, including the United States. For details, see How Google uses information from sites or apps that use its services and the Google Privacy Policy.
• If you’d rather not have this information collected, you can install the Google Analytics Opt-out Browser Add-on or block cookies in your browser settings. Blocking analytics cookies doesn’t affect any reminder features.

Ads and cookies

To keep the service free, this site may show Google AdSense ads.

• Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website and other websites.
• Google uses advertising cookies to show you personalized ads. You can opt out of personalized advertising in Google Ads Settings, and you can opt out of other third-party vendors’ use of cookies for personalized advertising at www.aboutads.info.
• To learn how Google uses data, see How Google uses information from sites or apps that use its services.
• Reminder features rely on a session cookie (wpr_sid) that is strictly necessary to provide the service. This cookie is never used for ads or analytics.

Sensitive information

Health-related details, such as medication names, can count as sensitive information if you put them in a reminder title. Where possible, please use general wording like “Lunchtime meds.” This service is a reminder aid and is not a substitute for medical advice or medication management.

Changes to this policy

We’ll post any changes to this policy on this page at least 7 days before they take effect. For changes that significantly affect you, such as changes to what we collect or how we use it, we’ll post them at least 30 days in advance.
