Terms of use
Effective November 11, 2026
These terms are an agreement between you and Zithron Inc. of Alberta, Canada ("we", "us"), which makes HushKin. By using the HushKin app or this website, you agree to them. Please also read our privacy policy.
HushKin isn't medical advice
HushKin helps you keep a record. It doesn't give medical advice, diagnose anything, or suggest doses, times or what's normal. Always talk to a doctor, midwife, nurse or pharmacist about your health or your child's.
In an emergency, call your local emergency number straight away: 911 in the USA and Canada, 999 in the UK, 112 in Nigeria where available. More support lines
1. Using HushKin
- HushKin is for parents, carers and people who are pregnant. You need to be old enough to agree to these terms where you live, or have a parent or guardian agree for you.
- Use it for your own family's records. Don't use it to break the law, to harm anyone, or to try to break, copy or get around how the app works.
- Resources and support lines in the app link to official websites run by others. We check them, but we don't control them, and they may change.
- Milestone checklists are the source's own words, shared with credit (for example, the US CDC's "Learn the Signs. Act Early."). They're for keeping a record, not for judging how a child is doing.
2. Your information is yours
- You own what you put into HushKin. It's stored on your phone, and we don't receive it.
- Because it's on your phone, keeping it safe is in your hands: back up regularly, keep your backup password, your HushKin PIN and its recovery code somewhere safe. We can't recover them, because we never have them.
- If your phone is lost or reset, or you delete the app, your records go with it unless you have a backup.
3. Premium (later)
HushKin doesn't sell anything yet. If we offer Premium, such as Family Sync:
- it will be billed by Apple's App Store or Google Play, under their terms;
- any free trial and the price will be shown before you buy;
- you can cancel any time in your App Store or Google Play account, and refunds are handled by them;
- if a subscription ends, nothing is deleted from your phone.
We'll update these terms before Premium is offered.
4. What belongs to us
The HushKin name, logo, app and website are ours or licensed to us. You may use the app for your own family, but not copy, sell or rebuild it.
5. No guarantees
We work hard to make HushKin reliable, but it's provided "as is". As far as the law allows, we don't promise it will always work without errors or that it suits every purpose. Nothing in these terms takes away rights you have by law as a consumer.
6. Limits on our responsibility
As far as the law allows, we're not responsible for losses that come from using or not being able to use HushKin, including lost records, or from relying on anything in it instead of professional advice. Where the law doesn't allow these limits, they apply only as far as it does.
7. Stopping
You can stop using HushKin at any time: Settings, then Delete all data, or uninstall the app. We may stop offering HushKin or parts of it; if we do, the records on your phone stay yours, and we'll give notice where we can so you can back up.
8. The law that applies
These terms are governed by the laws of the Province of Alberta and the federal laws of Canada that apply there. If you live elsewhere, you keep any protection the law where you live gives you.
9. Changes to these terms
If we change these terms, we'll update the date at the top. For important changes, we'll tell you in the app before they apply.
