Growline Tracker Privacy Policy
Developer: Dojoism
Last updated: May 9, 2026 · Publisher: Dojoism · App: Growline Tracker · Contact: support@dojoism.com
Growline is a personal health record tool for families. We are designed around a simple promise: your child's data belongs to you, not to us. We do not operate any servers that store your child's health data. We have no interest in your child's growth records beyond making Growline work on your devices.
Who We Are
Growline is built and operated by Dojoism. This Privacy Policy describes how the Growline iOS application handles personal information.
What Data Growline Handles
Growline lets you record information about a child you care for, including child profile details, growth measurements, derived percentiles, developmental milestones, illness episodes, vaccinations, attached photos, free-text notes, and feeding or sleep observations.
The following are accessed only when you explicitly enable them inside Growline. You can disable any of them at any time in iOS Settings:
- Apple Health (HealthKit): read or write height, weight, and head circumference samples for the child you designate, when you enable import or auto-sync.
- Photos: only the photos you choose to attach to a measurement, milestone, or photo entry. Growline does not scan or browse your photo library.
- Notifications: used to remind you of upcoming pediatric checkups, due vaccines, monthly growth letters, and your custom measurement schedule.
Growline does not collect third-party tracking data, advertising identifiers, profiling analytics, location data, microphone data, contacts, calendar access, or data sold, rented, or shared with brokers.
Where Your Data Is Stored
All measurements, photos, milestones, illness records, vaccines, and notes are stored locally using Apple's SwiftData framework on the device you record them on.
If you are signed in to iCloud, Growline uses Apple's private CloudKit database to sync your archive across your own Apple devices. This data is held in your iCloud account, accessible only to you. Dojoism cannot read it.
We do not operate any servers that store your child's health data, photos, or growth records. There is no Growline cloud account and no Growline backend that has access to your records.
Why We Handle Data
All data handling exists for a single purpose: to make the app work on your devices. Specifically:
- Display your records, charts, and timeline.
- Calculate growth percentiles using public WHO, CDC, and UK90 reference standards entirely on your device.
- Generate visit summary PDFs, monthly Growth Letters, and exportable archives.
- Sync your archive across your devices via your private iCloud, if you choose.
- Send local reminders for checkups, vaccines, and growth letters, if you grant notification permission.
We do not use your data for advertising, profiling, machine learning model training, or any commercial purpose beyond running the app.
Your Rights
You can export your full archive at any time as a JSON file from Family → Export Data. The export includes every measurement, milestone, illness, vaccine, photo, and growth letter, and is suitable for re-import into Growline or for your own records.
Deleting a child profile is a two-step confirmation. Deleted profiles are soft-deleted for 30 days so you can restore them, after which they are permanently removed from the device and your iCloud private database.
Because all your data lives on your device and in your private iCloud, you have full direct access. You can edit any record, restrict synchronization by signing out of iCloud, or stop using the app at any time.
Children's Privacy
Growline is intended for use by parents and caregivers of children. The app operates on a parental consent model: a parent installs the app, accepts these terms, and creates a profile for their child. The child is a profile within the parent's app; the child does not have an account of their own and does not interact with Growline directly.
Growline does not knowingly collect personal information directly from children under 13 or the equivalent age in your jurisdiction.
Apple Health (HealthKit) Data
If you grant Growline permission to access Apple Health, the app may read height, weight, and head circumference samples and write the same back to Apple Health for the child profile you designate. HealthKit data never leaves your device or iCloud, is never sent to Dojoism, and is never used for advertising or analytics. You can revoke any individual HealthKit permission at any time in iOS Settings.
Medical Disclaimer
Growline is a personal health record tool for families. It is not a medical device and does not provide medical advice, diagnosis, or treatment. Growth charts and percentiles are reference tools; they are not a measure of a child's health or your parenting. Always consult a qualified pediatrician for any concerns about your child's growth or development.
International Users
Because Growline does not transmit your records to any Dojoism server, your data does not cross borders by way of our infrastructure. Apple's iCloud services may store your data in regional data centers per Apple's own policies.
We acknowledge applicable regional laws including the EU General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA), the UK Data Protection Act, and the People's Republic of China Personal Information Protection Law (PIPL). Because Dojoism itself does not collect or process your child's records, most obligations under these laws apply to Apple as the iCloud service provider rather than to Dojoism.
Required Apple Privacy Manifest Disclosures
Per Apple's privacy framework, Growline declares health and fitness data, photos or videos, and other user content for app functionality only. None of them are linked to any tracking purpose.
API access is used for storing preferences, SwiftData/iCloud sync internals, development performance instrumentation, and checking space before exporting large archives.
Changes to This Policy
We may update this Privacy Policy as Growline evolves. Material changes will be communicated through an update note in the app and reflected in the Last updated date at the top of this page. Continued use of the app after a policy update constitutes acceptance of the revised terms.
