Terms of Use
The authoritative version of these Terms of Use is the Hungarian one; this English translation is for information only.
Effective: 2026-11-04. The same text is also available in the app.
The provider and the scope of these terms
The Resty baby diary mobile app and the resty.hu website are developed and operated by Beszteri Lajos, a private individual (hereinafter: the “provider”). Contact: lajos.beszteri@gmail.com. Hosting provider: Rackhost Zrt. (6722 Szeged, Tisza Lajos körút 41., Hungary).
These Terms of Use apply to the use of Resty. By installing and using the app you accept them; if you do not agree, do not use the app. The processing of personal data is described in a separate privacy notice (in the app and at resty.hu/adatkezeles/en).
The service
Resty is a free baby diary: it helps you record and review your child's sleep, feeding, growth, health, medicines and daily activities. It has no ads, purchases or subscriptions.
The app works fully without an account and without an internet connection: in that case all data stays on your phone only. You only need to create an account if you want to share the log with your family or use cloud backup.
The app's features may be extended, changed or discontinued.
Not a medical device
Resty is not a medical device: it does not make a diagnosis and does not replace a medical examination or advice. Its recommendations (e.g. sleep times), statistics and alerts (e.g. fever) are for information only, are based on international recommendations, and do not take your child's individual health condition into account.
If you are worried about your child's health, contact your paediatrician or the out-of-hours medical service; in an emergency, call 112.
Account and family sharing
An account may only be created by a person aged 18 or over. Only record data about a child you are responsible for (as a parent or guardian), or whose parent has agreed to it.
Keep your password secret. Only give the invite code to someone you want to share the log with: anyone who joins with the code can see and edit the data of every baby in the family.
You can delete your account at any time in the app (Family & sync → Delete account) or at resty.hu/fiok-torles/en.
Acceptable use
You may only use the app lawfully and for its intended purpose. It is prohibited to overload or disrupt the server, to attempt unauthorised access to another person's account or family, and to modify or reverse-engineer the app beyond what the law permits.
If someone seriously breaches these rules, the provider may suspend or delete their account; data stored on the phone is not affected.
Data and backup
Your entries are yours. Without an account the data exists only on your phone: if you delete the app or lose the phone, the data is lost too. To avoid this, turn on cloud backup (this requires an account).
The provider strives to keep the server running continuously and securely, but as a free service it does not guarantee uninterrupted availability. During maintenance or a failure the app keeps working on the phone, and syncing catches up later.
If the provider were to discontinue the server-based service (family sharing, cloud backup), it will notify you in the app at least 30 days in advance; the data on your phone will remain even then.
Liability
The app is provided free of charge and in its current state. The provider is not liable for decisions made on the basis of the app's data, recommendations and alerts, for the correctness of the data entered by the user, or for damage caused by failures of the internet connection, the phone or the app store.
Reminders (sleep and medicine reminders) are aids based on the settings entered by the user: their delivery depends on the phone's settings and operation (e.g. silent mode, battery saver, restart) and is therefore not guaranteed. The user is responsible for giving the medicine or vitamin, for its dose and for keeping to the times.
This limitation of liability does not apply to damage caused intentionally or by gross negligence, or to a breach of contract that harms life, physical integrity or health (Hungarian Civil Code, Ptk. 6:152. §), and it does not affect the rights to which a consumer is entitled by law and which cannot be excluded.
Intellectual property
The app (code, design, texts, icons) is the intellectual property of the provider. You receive a free, non-exclusive, non-transferable right to use it on your phone for your own non-commercial purposes. The open-source components used are subject to their own licences.
The growth charts are based on the public reference data of the WHO.
App stores
Google Play’s or the Apple App Store’s own terms also apply to downloading the app. Google and Apple are not parties to this agreement: the provider, not they, is responsible for the app, its content and its support, within the limits described under “Liability”.
Changes and termination
The provider may amend these Terms of Use (e.g. because of a new feature or a change in the law). It will inform you in advance about material changes in the app and on resty.hu; continuing to use the app after a change takes effect means you accept the amended terms.
The agreement ends when you delete the app and (if you have one) your account.
Complaints and disputes
You can send questions and complaints to lajos.beszteri@gmail.com or through the app’s “Send feedback” form; we reply within 30 days at most (in the case of the feedback form, only if you provided your e-mail address).
These Terms of Use are governed by Hungarian law; this does not deprive a consumer of the mandatory consumer protection rules of their country of residence. As a consumer you may also turn to the conciliation body or court of your place of residence.
