Terms of use
Last updated 17 August 2026. Provided by Nurhak Altin, the Netherlands. Contact: hallo@hodierna.app
Hodierna is not a medical device and gives no medical advice. It records what you type and reminds you at intervals you set. It cannot tell whether your baby is well, and a quiet phone never means anything is fine.
For anything clinical — feeding, weight, a temperature, a rash, or simply a feeling that something is off — contact your kraamzorg, verloskundige, huisarts or consultatiebureau. In an emergency call 112. Trust that instinct over anything on a screen.
1. What this is
Hodierna is a logbook for recording the care of a baby. You write things down; it keeps them, shows them back to you, and shares them with people you choose. That is the whole of what it promises.
2. Your account
You need an account, and you must be 16 or older to hold one. Keep your sign-in details to yourself; anything done through your account is treated as done by you. Tell us promptly if you think someone else has access.
3. Your data is yours
You keep every right in what you write. We claim no ownership of your entries, photos or documents, and we do not use them to train models or to advertise to you.
You give us only the permission needed to run the service: to store your content, to show it to the people you have invited, and to process it as you have asked (for example, when you ask a question of your own documents).
4. Sharing with other people
When you invite someone, you decide what they may do and when their access ends. You are responsible for who you invite. Anyone with permission to add entries can write in your logbook, and what they write is subject to these terms too.
If a professional carer records care here as part of her job, her employer may have its own legal duties about that record. Those duties are theirs. Hodierna is the tool, not the record-keeper of last resort.
5. Free and paid
The logbook is free, with no time limit and no entry limit. Premium adds document storage, search over those documents, and the AI features, at the prices shown in the app.
- Subscriptions are billed by Apple or Google, not by us, and renew until cancelled. Cancel in your Apple or Google account settings.
- A free trial converts to a paid subscription unless cancelled at least 24 hours before it ends.
- Refunds are handled by Apple or Google under their policies. We cannot issue them.
- If a payment fails or a subscription ends, the logbook keeps working. You lose the Premium features. Nothing you wrote is deleted or locked.
- AI features carry a fair-use allowance, shown in the app. It exists so that one unusual account cannot make the feature unaffordable for everyone.
If you are an EU consumer buying directly from us on the web, you have a 14-day right of withdrawal. Because access is immediate, you are asked to agree that performance begins at once, which ends that right — that consent is requested explicitly at checkout, not buried here.
6. Prices may change
If a price changes you will be told before it applies to you, and an existing subscription keeps its price until its next renewal. A price that was sold as one-off stays one-off.
7. What we ask of you
Do not use Hodierna to store someone else's records without their knowledge, to break the law, or to attack the service. Do not attempt to reach data that is not yours — access is checked on the server, and attempts are treated seriously.
8. Availability
We try to keep the service running and we do not promise it always will be. Hodierna is built to work offline precisely because networks and servers fail: your phone holds a complete copy, and you can log a feed at 3am whether or not anything else in the world is working.
We may change or discontinue features. If a feature you paid for is withdrawn, you will be told in advance and offered a refund of the unused part.
9. Ending it
You can delete your account at any time from the app. Everything is removed within 30 days.
Before that, export your data — it is one action in the app and it is yours to keep. We may suspend an account that is being used to attack the service or to harm someone, and we will say why.
If Hodierna itself shuts down, you will get at least 90 days' notice and an export of everything.
10. Liability
Hodierna is provided as it is. To the extent the law allows, we are not liable for indirect or consequential loss, and our total liability is limited to what you have paid in the previous 12 months.
Nothing here limits liability for death or personal injury caused by negligence, for fraud, or anything else that cannot lawfully be limited. If you are a consumer, your statutory rights under Dutch and EU law are unaffected by anything in this document.
To say the important part again: do not use this app as a reason to delay contacting a professional. It does not know anything about your baby's health.
11. Law
Dutch law applies, and the Dutch courts have jurisdiction. As a consumer you may also bring proceedings in the country where you live.
12. Changes to these terms
If these terms change materially you will be told in the app before the change takes effect. Continuing to use Hodierna after that means you accept them; if you do not, delete your account and take your data with you.
