Use the form below — it routes straight to our support inbox with everything we need to help. It helps if you include your device model and OS version, and — if you can — the app version. The quickest way is More → Help & about → Report a problem in the app, which attaches all three automatically. We never ask for your care logs; they stay on your device. Prefer to write directly instead? email us.
We only receive what you type here — your on-device care logs are never included.
You get full access during a 14-day free trial. After that, LittleRhythm Pro is $8.99/mo billed yearly ($107.98/yr, save $48) or $12.99/mo — the complete app either way, no separate feature tiers.
Yes — like any App Store / Play Store subscription, billing starts automatically unless you cancel before the trial ends. You can check or cancel anytime from your device's subscription settings; there's no separate LittleRhythm account to manage it from.
Refunds are handled by Apple or Google, not by us directly — we don't have access to process payments. Request one through Apple's "Report a Problem" or Google Play's subscription page. If you're stuck, submit a case above and we'll point you the right way.
On your device, encrypted — sleep, feeding, health notes, medications, milestones, all of it. We don't run a LittleRhythm account system and don't collect your care logs on a server of ours. See the full Privacy Policy for the details.
No. We don't sell or rent personal information, and we don't use advertising or cross-app tracking SDKs. A small number of optional features (AI insights, voice cloud assist, crash reporting) send limited, minimized data to named providers only when you turn them on — never your raw care logs.
An optional Pro feature that phrases your on-device insights in plain language. Only a pseudonymized summary (ages in weeks, counts, intervals) is sent — never names, photos, or free-text notes — through our broker to Anthropic (Claude), under a zero-retention, no model-training configuration. It's off unless you turn it on, and you can turn it off anytime.
Voice logging only listens when you tap the mic. Speech-to-text runs through your device's own OS recognizer (Apple or Google); we don't intentionally retain audio. Turning the transcript into a log entry happens on-device first, with optional cloud assist (text only, no audio) for phrases the on-device model can't handle — and only with your consent.
Create an encrypted export (or use your platform's own device backup), then import it on the new device. Your data is portable and yours — there's no account to sign back into.
Caregiver sync (Pro) keeps the same care log across a household's phones — including across iPhone and Android — without us ever running a sync server. Only end-to-end encrypted blobs are written to a cloud folder you choose (iCloud, Google Drive, Dropbox, etc.); the encryption key is shared device-to-device by scanning a QR code and never travels over the network. We can't read your data or even see that a sync happened.
Rotate the household key from within the app. A fresh encrypted snapshot is written under the new key and the old files stop being readable to the removed device — immediately, without needing to contact us.
Because everything lives on-device and encrypted, losing the device or deleting the app without a backup means that local copy of your data is gone with it. If you'd set up an export, a platform device backup, or caregiver sync to another phone, you can restore from one of those. We recommend keeping at least one of those current.
Subscriptions are billed by Apple or Google, not by us. Manage or cancel from your device's App Store / Play Store account settings — restore a prior purchase from within the app if needed.
Open LittleRhythm on the new device and use Restore purchase. It is on the first screen you see, and on the subscription screen (More → Help & about → Unlock LittleRhythm Pro). Your entitlement is tied to your Apple ID / Google account, not to the phone.
Please tell us: your device model, OS version and app version — or report from More → Help & about → Report a problem, which attaches them for you — plus what you were doing right before it happened, and whether it's repeatable. That context is the single biggest thing that speeds up a fix.
Yes — pick "Feature request" in the form above and describe what you're trying to do. We read every submission, even if we can't reply individually to every one.
Usually within 1–2 business days. Every case gets a short reference number
(like LR-7F3A9C) so you can refer back to it if you follow up.
In the app, open More → Privacy & data → Backup, then tap Delete all my data. This permanently wipes the on-device database, the encryption key, and any backups the app created. Because your data lives only on your device, this removes it completely — including rendering any residual encrypted sync copies unreadable. Need help? Email us or use the form above.
