DayRipple Privacy Policy

Effective date: July 15, 2026

DayRipple (the “Service”) treats your personal information with care and complies with applicable laws, including the Personal Information Protection Act of Korea.

1. Personal information we collect

Allowing calendar access does not, by itself, send any events off your device. We store the external calendar items above only for calendars you turn on with “Share with space members” on a device (only that device uploads them), and we never collect event notes, locations, attendees, or device calendar and event identifiers.

Payments are processed by the Apple App Store or Google Play. The Service does not collect or store payment method details such as card or bank account numbers.

PostHog usage statistics and Sentry error reports do not include your email, nickname, space names, relationship type, invite codes / links, the titles or memos of events, anniversaries, or to-dos, or payment transaction IDs / tokens. Except for the ads for free users in Russia and Belarus described below, we do not collect advertising identifiers; we also do not collect location, contacts, or photos, we do not track your activity across other companies’ apps or websites, and we do not use screen recording or session replay.

Ads for free users in Russia and Belarus: In-app purchases are not available in these two countries, so we show ads only to users there who have not paid, and give them higher free limits in return. Ads are served through the SDK of the ad mediation company Appodeal and its ad networks (myTarget(VK), BidMachine, Bigo Ads, Mintegral), and these companies process the ad info above under their own privacy policies. On the devices of users in other countries, we never start the ad SDK and collect no ad info. What you enter, such as events, anniversaries, and to-dos, is never sent to ad companies.

2. Purposes of use

• Member identification and login
• Sharing events, anniversaries, and to-dos among invited space members
• Showing the external calendar events you chose to share, and their last sync time, to members of the same space in their calendar and widgets (times are converted to the viewer’s time zone)
• Sending event / anniversary reminders and member-activity push notifications
• Where you have separately allowed it, sending re-engagement notifications tailored to your language, time zone, and current space status
• Verifying space lifetime and extra-seat entitlements and adjusting access on refund or cancellation
• Improving features through anonymous usage-flow analysis, only where you have explicitly allowed it
• Responding to errors and crashes and preventing duplicate charges and fraudulent use
• Showing ads to free users in Russia and Belarus and measuring ad performance

3. Retention and deletion

• When you delete your account, we promptly delete your account, profile, memberships, device tokens, product-improvement analytics choice, and the events, anniversaries, and to-dos you created.
• Spaces you used alone are deleted in full. Shared spaces where other members remain are transferred to those members, but content you created is deleted.
• A shared space’s purchase entitlement may remain on the space to protect other members, with its link to the deleted account removed.
• Shared external calendar events are replaced in full with the latest content when you open the app (if sharing is on on several devices, the content from the device that synced last), and events that ended more than 7 days ago are removed at the next sync.
• If you turn off calendar sharing or the external calendar connection on a device, the events you shared to that space are deleted right away (or at the next connection if you are offline). If sharing is also on on another device, they appear again the next time that device syncs, so turn it off on each device where you turned it on. Logging out deletes the events you shared to that device’s spaces just before you log out. Leaving or being removed from a space, or having your access to it suspended, immediately deletes the events you shared in that space.
• Shared events that have not been synced for more than 14 days (for example, if you were offline when logging out) are deleted by a daily cleanup job; they are uploaded again the next time you open the app on a device where sharing is on.
• PostHog is used in an anonymous analytics mode that does not create account IDs or personal profiles. On logout or account deletion, the device’s anonymous analytics identifier is reset, and already-aggregated anonymous statistics are not re-identified or linked to any specific account.
• Sentry error reports are retained for as long as operationally necessary, then deleted. New errors after account deletion do not include the deleted account’s internal user ID, and you can request deletion of existing error reports through the contact channel.
• Payment records required by applicable law, such as the Act on the Consumer Protection in Electronic Commerce, are stored separately for the statutory period, then destroyed.

Payment refunds and data retention

• If a space lifetime pass is refunded or canceled, paid features stop and the free limits apply again.
• Extra-seat transaction records and space data are not destroyed immediately. Members over capacity may have their access suspended rather than their data deleted.
• Once capacity is restored with a valid lifetime or extra-seat entitlement, suspended members are automatically reinstated in join order. Account deletion requests are handled separately from this policy.

4. Sharing with third parties and outsourcing of processing

The Service does not sell personal information. Ad info is provided to the ad companies below only when showing ads to free users in Russia and Belarus. The external calendar events you turn on with “Share with space members” (titles, dates, times, calendar name and color), the time zone of the uploading device, and the last sync time are, at your choice, visible to members of that space, including members who join later.

The following companies process data as our processors to operate the Service.

5. Your rights

Product-improvement analytics is off by default; we do not initialize PostHog or send usage statistics before you choose to allow or decline. Your choice is stored on your account and device and is honored after reinstall or a device change. You can turn analytics off at any time in the app settings, after which no new PostHog events are sent. You can turn external calendar sharing off per calendar in the app settings (on each device where you turned it on). You can also edit your profile and delete your account in the app settings; if you cannot access the app, you can use the web deletion request. On iOS, the advertising identifier is not sent if you decline tracking (you can change this at any time in Settings → Privacy & Security → Tracking); on Android, you can reset or delete your advertising ID in the Ads menu of your device settings.
