Lucarna

Terms of Use

Last updated: 22 October 2026

These terms apply when you use Lucarna, an app from Itworked Systems, a company registered in Türkiye ("we"). By using Lucarna you accept them. If you downloaded Lucarna from Apple's App Store, Apple's standard license agreement applies as well.

What Lucarna is, and what it is not

Lucarna asks one older person a few small questions each day, chosen by their family, and tells the family when a question with a deadline gets no answer by its time. It reports facts only. It does not interpret answers or judge anyone's health.

A notification can fail to arrive: a phone may be switched off, out of battery, out of signal, or set to silence notifications. Lucarna tells the family what it knows, and says so when it does not know. Do not rely on Lucarna as the only way to know someone is all right.

Who may use Lucarna

• Family members must be 18 or older.
• The person looked after must agree for themselves, on their own phone. None of their answers are shared until they do.
• They must be able to understand what they are agreeing to and decide for themselves. If a court has appointed someone to make decisions for them, Lucarna is not yet available for that situation.

The person looked after stays in control

They can see on their phone who sees their answers, turn off any question, and stop sharing at any time. No family member can turn a question they turned off back on, or undo Stop sharing. Please respect their choices.

Your account

You sign in with Apple or Google. Keep your phone and your sign-in secure. You are responsible for what is done with your account, and for inviting only people the person looked after would want to see their answers. You can delete your account at any time in the app (see Delete your Lucarna account).

Using Lucarna fairly

Do not:

• use Lucarna to watch someone who has not agreed, or who cannot agree;
• try to make Lucarna ask about things it refuses to ask (for example falls or measurements), or present it as an alarm or a safety service;
• try to get around Lucarna's security, or access anyone else's data;
• use Lucarna in a way that breaks the law.

We may suspend an account that does.

Paying for Lucarna

Lucarna is paid for with a plan: a subscription bought in the app from Apple's App Store or Google Play. One plan pays for one family, and anyone in the family can start it once the person looked after has agreed to share their answers. Lucarna asks the person the family's questions only while a plan pays for the family.

• Price: there is a monthly and a yearly plan. The app shows the price in your store's currency before anything is charged.
• Free days: your first plan starts with 14 free days where your store offers them to your account. The app says so before you start. After the free days the plan's price is charged, unless you cancel at least 24 hours before they end.
• Renewal: the plan renews by itself at the end of each month or year, and your store account is charged, until you cancel. Cancel at least 24 hours before the end of a period, and nothing more is charged.
• Cancelling: in your App Store or Google Play subscriptions. The plan then runs to the end of the period already paid for. Deleting your Lucarna account, or the app, does not cancel it.
• Who can change it: only the person whose plan it is, in their own store account. Everyone in the family can see whose plan it is and until when.
• One family each: a plan pays for one family. If you are in more than one family, another family needs a plan started by someone else in it.
• Payments and refunds: Apple or Google sells you the plan and takes the payment, and their terms apply, including for refunds. A refunded plan ends at once.

When a plan ends, Lucarna stops asking the person the family's questions, so nobody is told when a question gets no answer. The answers so far stay, and the plan can be started again at any time. If the price changes, your store tells you before it applies and, where its rules require, asks you to agree.

Changes to Lucarna and to these terms

We keep improving Lucarna and may change or stop features. If we change these terms, we update this page and the date at the top.

Our responsibility

We build Lucarna with care, but we provide it as it is and cannot promise it will always work. Nothing in these terms limits responsibility that the law does not allow us to limit, or your rights as a consumer.

Ending

You can stop using Lucarna and delete your account at any time. A family can stop looking after someone at any time in Settings.

Law

These terms are governed by the laws of the Republic of Türkiye, and disputes go to the competent courts and enforcement offices of Türkiye. If you are a consumer, you also keep the protection of the mandatory laws of the country where you live, and you can take a dispute to the courts or consumer bodies there.
