Frequently asked questions

What's the difference between Free, Gulu Family and Gulu Plus?

• Free: all logging features on your device, plus family sync for up to 3 phones or tablets per family.
• Gulu Family (US$1.99 a month or US$14.99 a year in the US): sync for more than 3 devices, and Apple Watch.
• Gulu Plus (US$3.99 a month or US$29.99 a year in the US, with a 14-day free trial on yearly): everything in Gulu Family, plus AI features (voice and photo logging, AI summaries on demand, alerts and doctor-visit briefs).

Elsewhere, Apple's converted local prices apply; the App Store price is the one that counts. A paid plan covers the whole family: when one person subscribes, every member can use it.

How do I invite family members?

1. Go to More → Family Sync, sign in with your email and create a family.
2. Tap "Get invite code" and share the 6-character family code. A code is valid for 24 hours and works for up to 5 phones.
3. Your family member installs Gulu, goes to More → Family Sync → Join a family and enters the code.

Before you create or join a family, the app explains what will be uploaded and asks for your consent. A free family can sync up to 3 phones or tablets (see the next question). Every member can see all of the family's records, so share the code only with people you trust. The family owner can remove a member by swiping left on them in the member list.

How many devices can a free family have? What about a 4th?

A free family can sync up to 3 phones or tablets, counted in the order they joined. Apple Watch doesn't take a place, but needs Gulu Family or Gulu Plus.

• Without Gulu Family or Gulu Plus, a 4th device that tries to join is asked to upgrade. It does not join and uploads nothing, but it still works normally on its own.
• The family owner can free up a place by swiping left on an unused device in the member list; the new device can then join.
• If a paid plan ends while the family has more than 3, the 3 that joined first keep syncing and the newer ones stop. Logging on those devices carries on and no data is deleted; syncing resumes when you resubscribe or remove an older device.

We each created a profile for our baby. Will joining a family create duplicates?

If the family you join already has a baby, the app asks whether it is the same child. If you choose to merge, the records on your phone move to the family's baby and are not duplicated.

How do I pair my Apple Watch?

1. On your iPhone, sign in with your email and make sure your family has Gulu Family or Gulu Plus (Apple Watch isn't included in Free).
2. Install Gulu on your watch.
3. Open Gulu on your iPhone, go to More → Apple Watch and tap "Pair".
4. Open Gulu on your watch. It asks your iPhone for a pairing code by itself and finishes in a few seconds.

Your watch syncs the same records as your iPhone and follows its baby, caregiver, units and language. To stop syncing, tap "Unpair" on the same screen.

I have a new phone or reinstalled the app. How do I restore my purchase and records?

Purchase: sign in to the App Store with the Apple Account you used to subscribe, then tap "Restore Purchases" on the More → Gulu Plus screen in the app. If a family member subscribed to Gulu Family or Gulu Plus, just join their family; there is nothing to restore.

Records: if you are in a family (free or paid), sign in with the same email on the new phone to return to it, and your records sync down. Without family sync, records live only on the old device: make a JSON backup there first, then use "Restore from backup" on the new device (see "Exports and backups" below).

How do I upgrade from Gulu Family to Gulu Plus?

On the More → Gulu Plus screen, choose a Gulu Plus option and confirm the purchase. The upgrade takes effect immediately and AI features are available straight away; Apple refunds the unused part of your Gulu Family period on a prorated basis. Both plans are in the same subscription group, so you are not charged twice.

To downgrade from Gulu Plus to Gulu Family, go to Settings → Apple Account → Subscriptions on your iPhone, choose Gulu and select Gulu Family. The downgrade takes effect at your next renewal; until then you keep Gulu Plus.

How do I cancel my subscription?

On your iPhone, go to Settings → Apple Account → Subscriptions, choose Gulu and tap "Cancel Subscription". Cancel at least 24 hours before the current period ends, or it will renew. Deleting the app or your Gulu account does not cancel your subscription.

Refunds are handled by Apple: request one at reportaproblem.apple.com.

What happens to my records when a paid plan ends?

The family returns to Free: AI features stop and Apple Watch stops syncing. If the family has more than 3 phones or tablets, the 3 that joined first keep syncing and the newer ones stop. All records on every device stay, and you can keep logging. Nothing on our servers is deleted because the plan ended, and syncing picks up where it left off when you resubscribe.

How do I delete my account?

Go to More → Account → Delete Account. All devices on the account, including your watch, are signed out at once. If no one else is in the family, the family and all its records are deleted from our servers immediately; if other members remain, the family continues and the records you entered stay visible to them. Deleting your account does not delete the records on your phone and does not cancel your Apple subscription.

How do I export or back up my records?

• Export CSV: in More → Export, choose the baby and date range, then share or save the file. It opens in Excel or Numbers.
• Backup (JSON): in More → Backup. A backup contains all babies and records and can be fully restored. When restoring, choose "Merge" (keeps your existing data) or "Replace" (deletes current data first, then imports; this cannot be undone).

You keep these files yourself; we don't receive them.

My records aren't syncing. What should I do?

Check that both devices are online and in the same family. If the family has more than 3 phones or tablets, or for Apple Watch, also check that the family's Gulu Family or Gulu Plus plan is active. If it still doesn't work, export the "write log" from the app's settings and send it to us. The write log records only when each save happened, its type and whether it worked; it contains no notes or names.

The AI got something wrong. What should I do?

Just edit or delete that entry. AI output can be wrong and is not medical advice. If you have concerns about your baby's health, talk to a doctor; in an emergency, call your local emergency number.

Where is my data stored, and who can see it?

Without family sync, records stay on your device. Once you create or join a family (free or paid), records are stored on our servers in the United States and every member of your family can see them. You can withdraw consent under More → Account → Family sync consent; withdrawing means leaving the family. AI features are part of Gulu Plus only and are used only with your consent. See the Privacy Policy, or email us with any other data questions.
