JaiSupport
Need help, found a bug, or want to suggest something? Email alpetraapps@gmail.com. I read every message and usually reply within two business days. It helps to include your phone model, your Android or iOS version, and the app version shown in Settings › About Jai.
Please don’t send your baby’s records or medical questions. For any doubt about your baby’s health, talk to your pediatrician.
Getting started
Do I need an account?
No. Jai has no account. Open the app, add your baby and start logging.
How do I add another phone?
On the phone that has your baby: Settings › Family › Add phone, which shows a QR code. On the new phone, choose Join a family and read the code. Both phones need Jai open, on the same Wi‑Fi. A family can have up to 5 phones, on Android and iPhone.
Syncing
The phones aren’t syncing.
- Check that both phones are on the same Wi‑Fi network, with Jai open.
- Guest networks and networks with client isolation keep phones from seeing each other. Try another network or a hotspot.
- iPhone: in Settings → Jai, “Local Network” has to be on.
- Android: on some phones (Xiaomi, Samsung, Huawei), take Jai out of battery optimization.
- If it says the app versions differ, update Jai on both phones.
Does it sync when Jai is closed?
Android: yes, with Sync in the background on, which is why a quiet notification shows. iPhone: only with Sync away from home on. On home Wi‑Fi alone, iOS doesn’t allow it, so the iPhone sends and gets everything when you open Jai.
Does it sync away from home?
With Sync away from home on, which is a Premium option. Entries travel sealed with your family’s key, and not even the developer can open them.
How do I remove a phone?
A phone can leave at any time with Settings › Family › Leave the family, and the others don’t need to do anything. Removing another phone restarts the family: each phone that stays reads a new QR code. No records are lost.
Your data
Where are my records?
On your family’s phones. They aren’t stored on a server the developer can restore from. See the Privacy Policy for the details.
How do I move to a new phone?
If another phone in your family has the records, join the family from the new phone. Otherwise, use Settings › Your data › Export a backup, then Import a backup on the new phone. Milestone photos stay on the old phone.
I deleted the app. Can I get my records back?
Only from another phone in your family, a backup file you exported, or your phone’s own Google or Apple backup, if it had one. The developer has no copy.
How do I delete my data?
- This phone: Settings › Your data › Delete this phone’s data. This can’t be undone.
- The server: Settings › Your data › Delete the data on the server. This turns off sync away from home for the whole family, and every phone keeps its entries.
- Usage statistics: turn them off in Settings › Your data.
There is no account to delete.
Premium
What is free, and what is Premium?
Free: unlimited logging, the last 48 hours of history, growth, full backups, Wi‑Fi sync and one baby. Premium adds the full history, 7‑ and 30‑day summaries, widgets and the lock screen timer, reminders, more babies, color themes, the CSV table and sync away from home. Nothing is ever deleted: older history is only hidden.
Does one purchase cover the whole family?
Yes, up to 5 phones in the same family, on Android and iPhone.
How do I cancel?
Subscriptions are billed and cancelled in the store you bought from, not in the app. Deleting the app doesn’t cancel them.
- iPhone: Settings → tap your name → Subscriptions.
- Android: Google Play Store → your profile → Payments and subscriptions → Subscriptions.
If you cancel a free trial at least 24 hours before it ends, you aren’t charged.
I paid, but Premium isn’t unlocked.
Open the Premium screen and tap Restore purchases, signed in with the store account you bought with. On other phones, check that they are in the same family. If that doesn’t work, email me with the approximate purchase date.
Can I get a refund?
Refunds are handled by the store. iPhone: reportaproblem.apple.com. Android: your Google Play order history.
Requirements
- iPhone: iOS 17 or later. There is no iPad version.
- Android: Android 8.0 or later.
