Privacy Policy

Effective date: July 4, 2026 · Version 1.2

This Privacy Policy explains how GYST Baby LLC, the owner and operator of the GYST Baby application ("GYST," "we," "us," "our"), handles information. By using GYST you agree to this policy.

The short version

The information you enter stays in your hands: on your device and, if you're signed in to iCloud, synced through your own private iCloud account so your plan appears on your other devices. We do not operate accounts, we do not run servers that collect your data, and we do not sell your information or use it for advertising. We cannot read what's in your iCloud.

What is stored on your device

When you set up and use GYST, the following is stored locally on your device:

• Your due date or your child's birthday, and an optional name or nickname.
• Your plan: generated tasks, appointments, milestones, and the items you check off.
• Events, notes, and questions you add.
• Shopping-list details you enter (stores, links, prices, who's buying).
• Family members and caregivers you add (a name and role only — used to organize buying and sharing; we never contact them and they are not accounts).
• Developmental milestones you mark as observed.
• Your reminder and notification preferences.

This information stays on your device and within your device's own backup/sync (for example, an encrypted device backup you control). We do not receive it.

iCloud sync

If you are signed in to iCloud, GYST stores your information in your private iCloud database using Apple's CloudKit service, so the same plan appears on your iPhone, iPad, and Mac. That data lives in your Apple Account, is protected by Apple's iCloud security (encrypted in transit and on Apple's servers), and is accessible only to you — not to us. We have no servers and no way to read it. If you sign out of iCloud or disable iCloud Drive for GYST in your device settings, your information simply stays on the device. Apple's handling of iCloud data is governed by Apple's own privacy policy.

Notifications

If you enable reminders, GYST schedules local notifications on your device through the operating system. You can change or revoke notification permission at any time in your device settings.

What we do not do (current version)

• We do not collect, transmit, or store your personal information on our servers.
• We do not sell or rent your information.
• We do not use third-party advertising or tracking SDKs.
• We do not knowingly build profiles about you or your child.

Children's privacy

GYST is intended for adults (18+) organizing their own pregnancy or parenting journey. It is not directed to children, and we do not knowingly collect personal information from children. Information you choose to record about your child is stored on your device under your control. If you believe a child has used GYST to provide information to us, contact us and we will address it.

Sharing with family (share-sheet exports)

GYST includes share buttons that compose a plain-text summary (for example, a shopping list, your to-do list, a weekly update, or milestone progress) and hand it to your device's standard share sheet. Nothing is shared automatically and nothing passes through our servers — the content goes only where you send it (for example, Messages or email), under the terms of the app you send it with. Think before you share information about your child, and get permission before sharing information about other people.

Baby shower wish list (optional)

If you choose to publish a wish list, only the item names, notes, and quantities you pick are copied to the public area of your own iCloud container under a long random link code, so guests with the link can view them at gystbaby.com/wishlist. Guests who mark an item as purchased may enter a first name, which is stored alongside the item in your iCloud container and shown to you in the app. Our website passes these requests through without storing anything — no accounts, no cookies for guests, no analytics. Taking the list down in the app deletes the published records and the link stops working. Prices, stores, and your other GYST data are never published.

Future features (products, sponsors)

As GYST grows, we may add features such as shared household plans, optional analytics, product links, affiliate programs, or sponsored content. Before any feature that changes how information is collected, used, or shared takes effect, we will update this policy, update the version and effective date, and ask you to review it. When affiliate or sponsored features are added, we will disclose material connections clearly and, where required, comply with U.S. Federal Trade Commission guidance. We will describe at that time exactly what (if anything) is collected, why, and your choices.

Third-party links

If GYST links to third-party products, retailers, registries, or websites, those parties have their own privacy practices that we do not control. Review their policies before providing information to them.

Your choices and rights

• Delete everything: Settings → "Erase all data" permanently removes your plan, events, tasks, and questions from the app on your device; if iCloud sync is active, the deletion syncs to your private iCloud database and your other devices as well.
• Notifications: manage or revoke permission in your device settings at any time.
• Because we do not collect your information on our servers in this version, there is nothing for us to access, correct, or delete on our side. Depending on where you live, you may have additional rights under laws such as the GDPR or CCPA/CPRA; if and when we begin collecting personal information, this policy will explain how to exercise them.

Security

No method of storage is perfectly secure, but keeping your information on your own device — rather than on our servers — reduces exposure. Protect your device with a passcode and keep your operating system up to date. You are responsible for the security of your device and backups.

Data retention

Your information remains on your device until you delete it (by erasing data in Settings or removing the app). We do not retain copies of it.

International users

GYST is operated from the United States and reflects U.S. guidance and law. If you use GYST from elsewhere, you are responsible for compliance with your local laws, and local data-protection rights may apply.

Changes to this policy

We may update this policy. Material changes will be reflected in a new version and effective date, and you will be asked to review the current version. Prior accepted versions remain available in Settings.
