Privacy Policy

• Baby activity records (feeding times and amounts, sleep sessions, diaper changes, growth measurements, health events, and custom entries) entered manually by you. • A device identifier generated on your device, used solely to identify your device within a family sync group. • Your selected country, language, and unit preferences. • The version of these terms you accepted and the timestamp of acceptance. • Questions and limited activity context submitted to the AI assistant during a session (see Section 3). • Photos and videos you choose to add to Memories — stored only on your device and never transmitted to our servers (see Section 4).

• We do not collect your name, email address, phone number, or any other personal identifier unless you voluntarily include it in a note or AI message. • We do not collect precise or approximate location data. • We do not use third-party advertising SDKs or analytics that track you across apps. • We do not use your baby's activity data or AI session data to train AI models. • We do not upload, access, or store photos or videos from the Memories feature on our servers.

When you use the AI assistant, your question and relevant activity context (such as recent feeding or sleep summaries) are transmitted to a third-party AI provider to generate a response. IMPORTANT LIMITATIONS: • This data is transmitted to an external AI provider that we do not control. Once data leaves our servers en route to the AI provider, it is subject to that provider's own privacy policy and data retention practices. • We do not permanently store AI session messages on our own servers beyond the time needed to forward the request and return the response. However, we cannot guarantee or represent what the AI provider retains or how long they retain it. • The AI provider used depends on your region. Users in mainland China are served by a provider operating within China (Aliyun / DashScope). Users outside mainland China are served by an international provider. Each provider has its own independent privacy policy. • Do not include sensitive personal information, medical details, or information you would not want transmitted to a third-party AI provider in your AI assistant messages.

The Memories feature lets you capture and keep photos and videos of your baby's milestones. All media files you add to Memories are stored exclusively on your device's local storage. • We do not upload, access, or transmit your Memories photos or videos to our servers or to any third party. • Media files are never included in family sync transfers. • Deleting a memory from the app permanently removes both the record and the associated media files from your device. • We have no ability to recover media files deleted through the app or through device storage management. You are solely responsible for backing up media you wish to preserve. We recommend exporting important photos and videos to your device's photo library or a cloud backup service of your choice.

Activity records exist solely for your own reference and, when Family Sharing is enabled, to sync to your family's devices. We do not analyse, aggregate, or monetise your baby's activity data. Device identifiers and legal acceptance records are stored on our servers solely to operate the sync service and to maintain an audit record of consent as required by applicable law.

When you enable Family Sharing, activity records are temporarily stored on our servers in encrypted form during transit. Records are deleted from our servers after all devices in your family group have confirmed receipt. Only devices that share your family group code can access your sync records. Memories (photos and videos) are not included in Family Sharing sync. Media files remain local to the device on which they were added. We make reasonable efforts to protect synced data, but we do not guarantee that data will be available, intact, or recoverable at any time. You are responsible for maintaining your own local backups.

Local data remains on your device until you delete the app or clear its data. We have no ability to recover locally deleted data. Sync records are deleted from our servers after all family members have acknowledged receipt. AI session data is not retained on our servers beyond the time needed to generate a response; however, the third-party AI provider may retain it per their own policy (see Section 3). Legal acceptance records (device ID, accepted versions, and timestamps) are retained for as long as required by applicable law. When retention is no longer required, records are deleted.

Data in transit is protected by TLS encryption. We apply industry-standard practices to protect data at rest on our servers. No method of electronic transmission or storage is completely secure. We cannot guarantee the absolute security of data you transmit to us or data we hold, and we disclaim liability for unauthorised access, disclosure, alteration, or destruction of your data to the fullest extent permitted by applicable law.

LemonTree is designed to be used by adults to record data about their children. We do not knowingly collect personal information directly from children. The app is not directed at children under 13 (or the applicable age of digital consent in your jurisdiction) and requires users to confirm they are 18 or older. If you believe we have inadvertently collected information from a minor, please contact us and we will delete it promptly.

Depending on your country or region, you may have the right to access, correct, or request deletion of data we hold about your device identifier and legal acceptance records. Users in the European Economic Area have rights under the GDPR, including data portability. Users in mainland China have rights under the Personal Information Protection Law (PIPL). These rights apply only to data held on our servers. We have no access to data stored locally on your device, including Memories media files. To exercise your rights, please use the Send Feedback option in Settings. We will respond within 30 days. We cannot guarantee retrieval or deletion of data that has already been transmitted to a third-party AI provider, as that data is subject to the provider's own policies.

We use third-party services to operate LemonTree, including cloud storage providers (for sync and legal records) and AI providers (for the AI assistant). These providers operate under their own privacy policies and terms of service, which we encourage you to review. While we take reasonable steps to select providers that meet applicable legal standards, we cannot guarantee their practices and disclaim liability for how third-party providers handle data to the fullest extent permitted by applicable law.

We make no representation about the accuracy, completeness, or reliability of data stored in or transmitted through LemonTree. All records are entered manually by users, and we are not responsible for errors, omissions, or inaccuracies in user-entered data.

When we make material changes to this policy, we will increment the version number and prompt you to review the updated policy in the app. Continued use of the app after the effective date of a revised policy constitutes your acceptance of the changes.
