Terms of use
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, it never interprets a measurement, 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 the people who see your baby: your midwife, health visitor, paediatrician or doctor, and in the Netherlands your kraamzorg, verloskundige, consultatiebureau or huisarts. In an emergency call your local emergency number — 112 across the EU, 911 in the United States and Canada, 999 in the United Kingdom. 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.
It is not a medical record system, it is not certified as one, and it is not a substitute for the records your care providers keep. Nothing in it is designed to diagnose, treat, monitor or predict anything.
2. Who you are contracting with
Hodierna is made by Nurhak Altın in the Netherlands. Contact: hallo@hodierna.app, which reaches a person rather than a queue.
When you buy a subscription or a credit pack, your contract for that purchase is with Apple or Google, who sell it as merchant of record. Your contract for using the app is with us.
3. 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.
4. 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. That permission ends when you delete the content or the account.
5. Sharing, and professional carers
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 log can write in your logbook, and what they write is subject to these terms too.
A professional carer cannot find you or let herself in. She is either invited by you, or she asks and you approve; an organisation that rosters her produces a request, never access. Grants to professionals carry an end date and stop on their own.
If a professional records care here as part of her job — including notes about the mother's recovery — her employer has its own legal duties about that record, and for that content they are the responsible party. Hodierna is the tool, not the record-keeper of last resort, and it is not a substitute for the record her employer is legally required to keep.
6. Free and paid
The logbook is free, with no time limit and no entry limit, and it works with no signal. That is not a trial and it does not expire.
Two separate things are sold, and they work differently on purpose:
- Premium adds document storage, search over those documents, and the full archive. It is sold monthly, yearly, or once for good, at the prices shown in the app.
- AI credits are bought in packs, separately from any plan. They are spent by the optional AI features — turning a sentence or a photographed page into entries, indexing a document, asking a question of your documents — at the rates shown in the app. Credits work on any plan, including the free one.
About subscriptions:
- Billing is by Apple or Google, not by us. A subscription renews until you cancel it, which you do in your Apple or Google account settings.
- A free trial converts to a paid subscription unless cancelled at least 24 hours before it ends.
- If a payment fails or a subscription ends, the logbook keeps working. You lose the Premium features. Nothing you wrote is deleted or locked.
About credits:
- They do not expire, and they are not a subscription. Buying credits does not sign you up to anything.
- They are spent when an AI operation runs. If the operation fails, the credits are returned to your balance automatically.
- Credits already spent cannot be refunded, and unspent credits are not exchangeable for money.
- They belong to your account and cannot be transferred to another account.
7. Refunds and your right to change your mind
As a consumer in the EU you have a 14-day right of withdrawal on digital content. Because Apple and Google sell these purchases as merchant of record, that right is exercised through them: their checkout is where you consent to immediate delivery, and their refund process is the one that applies.
We cannot issue a refund for a store purchase — we never receive the payment and have no ability to reverse it. Ask Apple or Google. If they refund you, the corresponding Premium access or credits are removed.
We do not currently sell anything directly on this website. If that ever changes, the withdrawal right and the way to exercise it will be set out at checkout, not buried here.
8. 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.
9. 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.
10. 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.
11. Ending it
You can delete your account at any time from the app. The request waits seven days, during which you can cancel it, and then everything is destroyed — see deleting your account.
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.
12. Liability
Hodierna is provided as it is. We are liable for damage caused by our intent or gross negligence, for death or personal injury, and for anything else that cannot lawfully be excluded — none of that is limited here. Beyond it, and to the extent Dutch law allows against a consumer, we are not liable for indirect or consequential loss, and our total liability is limited to what you have paid us in the previous 12 months.
If you are a consumer, your statutory rights under Dutch and EU law apply in full and nothing in this document reduces them. Where a term here would be unreasonable against a consumer, the statutory rule wins.
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, and it will never tell you that something is fine.
13. Law and disputes
Dutch law applies, and the Dutch courts have jurisdiction. As a consumer you keep the protection of the mandatory law of the country you live in, and you may bring proceedings there.
You can also use the European Commission's online dispute resolution platform. We would rather you emailed us first — hallo@hodierna.app — because most of this is fixable.
14. 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.
