한국어 버전: 개인정보 처리방침

1. Information We Collect

DaySeed only collects the following. • Email address (account creation and magic-link authentication) • Seed definitions (name, color, time range) and completion records you enter • Notification permission status on your device • A single photo you choose to submit (used to extract event details) • Your nickname and email when you set up sharing (shown to your partner) • A device push token for notifications • Anonymous usage statistics (which features are used and how often; not linked to your account; can be turned off in Settings › Data) • Purchase receipts and premium entitlement status (RevenueCat) • Advertising identifier (only with App Tracking Transparency consent on iOS, Google AdMob) The photo is discarded immediately after extraction; dayseed does not store this photo. We do not collect precise location or contacts. If you turn on "Show device calendar", events from the iOS Calendar are read and displayed on your device only. They are never sent to our servers or shared with your partner.

2. Purposes

Collected information is used only for the following purposes. • Account authentication and verification • Syncing seeds and records across your devices • Sending timed reminders • Extracting event details from a photo you choose to submit • Notifying your sharing partner about event changes • Understanding feature usage and improving the Service (anonymous statistics you can turn off) • Serving ads and processing premium purchases

3. Retention

Your data is securely retained as long as your account is active. When you delete your account, all personal data is permanently removed immediately. The photo you submit when adding an event from a picture is an exception: it is discarded immediately after extraction and is never stored on our servers or in logs.

4. Third-Party Sharing

We do not sell or share your personal data with advertisers, data brokers, or analytics vendors. The Service is operated through these processors. • Supabase (database and authentication) — United States • Apple Push Notification Service / Firebase Cloud Messaging (notification delivery) • OpenAI (vision AI model provider used to read event details from your photo) — only the single photo you choose is sent, and dayseed does not store it. The provider may retain it for a period under its own policy • PostHog (anonymous usage statistics) — uses a random identifier not linked to your account or email; can be turned off in Settings • Google AdMob (advertising) and RevenueCat (premium purchases) — see "Advertising and Purchases" • Kakao (place search) — only the search text you type is sent and is not stored These processors handle only the minimum data required to operate the Service, under their own security policies.

5. Your Rights

You may exercise the following rights at any time. • Access, correct, or delete your data • Revoke notification permission (device settings) • Delete your account (Settings → Delete account)

6. Security

All traffic is encrypted via HTTPS. The database enforces row-level security so each user can only access their own data. Sign-in uses magic links instead of passwords, eliminating password breach risks.

7. Children's Privacy

DaySeed does not knowingly collect personal information from children under 14. Users under 14 require guardian consent.

8. Advertising and Purchases

DaySeed serves ads via Google AdMob. The following information may be processed. • Advertising Identifier (IDFA): used only with App Tracking Transparency (ATT) consent on iOS • Device information: for ad delivery optimization • Approximate location (IP-based): for regional ad targeting Premium purchases are processed via RevenueCat and the Apple App Store. Purchase receipts and an anonymized user identifier are stored by RevenueCat. Payment details (card numbers, etc.) are handled exclusively by Apple and are never shared with DaySeed.
