What you write stays yours
This policy describes what data the Nuji app processes on iOS and Android, where that data is stored, who can access it, and what you can do with it. The journal is the most personal part of an app like this, so we built Nuji so that what you write never reaches us.
In short
- There is no account and no server of our own. Your journal, your voice notes and your settings exist only on your phone, and we neither see nor receive them.
- Reflections are created on your device, based on rules. We don’t send your text anywhere, and we don’t use it to train artificial intelligence.
- In the free version, Google AdMob shows ads, and for this Google processes device and usage data. With a Premium subscription there are no ads.
- We use no analytics and no crash reporting service of our own, and we sell no data.
1. The controller
The developer of the app and the controller under this policy is: [kitöltendő: name], [kitöltendő: address]. Contact for privacy matters: hello@nuji.hu. We respond to requests within 30 days at the latest. Data processing is governed by the General Data Protection Regulation (GDPR) of the European Union and the Hungarian Act on the Right to Informational Self-Determination.
2. Data that stays on your phone
The app stores the data below exclusively in your phone’s own storage, which other apps cannot access. We don’t transmit it anywhere, and we can’t access it either. The purpose in every case is for the app to work and for you to be able to read back what you recorded.
| Data | What it contains |
|---|---|
| Journal entries and drafts | The text of your morning, evening and gratitude journals and the classic templates. |
| Mood and body sensation | The mood and body sensation you mark on each entry. |
| Voice notes | The audio files (.m4a) recorded for your journal, only if you record any. |
| Saved affirmations | The sentences you marked as favorites. |
| Rituals and settings | The steps of your morning and evening sequence, reminder times, quiet hours, and your first name if you enter it. |
| Statistics | Your streak, minutes spent practicing and exercises completed, from which the mood map and the yearly summary are made. |
| Subscription status | A flag showing whether you have a valid Premium subscription. We never see your payment details. |
The reflections you receive on your entries are created on your device using rule-based text processing, with no language model and no network connection. Reminders are local notifications: your phone’s operating system schedules and displays them, with no server involved.
The home screen widget receives the daily affirmations for the next two weeks through a shared storage that only the app and the widget can access. The widget sees nothing from your journal.
3. Backup and deletion
Because nothing is stored on our side, we cannot restore your entries if you lose or replace your phone. Your phone’s own backup may, however, contain the app’s data: an iCloud or computer backup on iPhone, and Google’s automatic backup on Android. These are managed by Apple or Google in your account, under their own privacy terms, and you can also switch them off in your phone’s settings.
To delete all data, delete the app from your phone. This permanently removes the journal, the voice notes and all settings from the device. If your phone has a backup, you can remove the copy stored there by deleting the backup.
4. Ads: Google AdMob
In the free version, an ad banner appears on the home screen, and a full-screen ad may appear after you finish an exercise. The ads are served by Google AdMob (Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland). With a Premium subscription, the app neither requests nor shows ads.
What data Google processes
To serve ads, the Google SDK may collect the following from your phone: the device model, the operating system version, the IP address and the approximate location estimated from it, the app identifier, interactions with ads (impressions, taps), and the advertising identifier. On Android this is the Google advertising ID, and on iPhone it is Apple’s advertising identifier (IDFA), but the latter only if you have allowed tracking in your iPhone settings. The Google SDK has no access to your journal, your voice notes or any other data stored on your phone.
Purpose and legal basis
The purpose is to show ads, measure impressions and filter out abuse, which finances keeping the free version available. Personalized ads and the use of identifiers stored on the device require your consent (GDPR Article 6(1)(a)). Without consent, Google can only show non-personalized ads, for which it processes limited data on the basis of a legitimate interest in operating the ad system and preventing fraud (GDPR Article 6(1)(f)).
How you can limit it
In the EEA, when you first launch the free version, Google’s consent dialog asks whether you agree to personalized ads, and on iPhone Apple’s tracking permission request appears after that. You can change your decision at any time in the app under Profile, Ad privacy settings. On iPhone you can also block tracking under Settings, Privacy & Security, Tracking. On Android you can delete or reset the advertising ID under Settings, Google, Ads. Turning ads off completely requires a Premium subscription. You can read about Google’s data processing in Google’s Privacy Policy and on the page about how Google uses information from sites or apps that use its services.
5. Purchases and subscriptions
You can buy a Nuji Premium subscription through the payment system of the Apple App Store or Google Play. They handle the payment entirely, and we never see card numbers or billing details. On the phone, the app only checks with Apple’s or Google’s system whether you have a valid subscription. The legal basis for this processing is the performance of a contract (GDPR Article 6(1)(b)). The stores’ own data processing is described in the privacy notices of Apple and Google.
6. Permissions the app requests
- Notifications: so that the ritual and other reminders arrive at the time you set. You can decline, and the app works without them.
- Microphone: the app asks only when you first record a voice note in the journal. The recording stays on your phone.
- Photos (add only, on iPhone): so that you can save a shareable affirmation card to your gallery. The app has no access to your existing photos.
- Background audio (on iPhone): so that an exercise doesn’t stop when the screen is locked.
- On Android, additionally: internet (purchases and ads), vibration (for the breathing rhythm), running at startup (so reminders survive a restart), and reading the advertising ID for the ads in the free version.
7. What we do not collect
The app has no account registration, and no email address or password. We don’t ask for access to your precise location, your contacts, the camera or your existing photos. We don’t ask for HealthKit or Health Connect access. We use no analytics tool, no crash reporting service of our own and no marketing tracking code, and we don’t analyze the text of your journal in any form outside your phone.
8. Notification about the iPhone launch
While the iPhone app has not been released, you can sign up on the website to be told when it becomes available. We ask only for your email address, and we store it only after you confirm it with the button in the email we send. We keep the address with our email service provider (Resend) and use it to announce the release and, rarely, for Nuji news. The legal basis is your consent. Every email contains an unsubscribe link, and you can ask us at any time at hello@nuji.hu to delete your address.
9. Transfers outside the EU
We ourselves do not transfer any data. Resend may also store the email addresses for the launch notification in the United States. Google may also process the data collected for ads outside the European Union, for example in the United States. This happens on the basis of the EU-US data privacy framework or the standard contractual clauses approved by the European Commission.
10. Your rights
Under the GDPR you have the right of access, rectification, erasure, restriction of processing, data portability, objection, and withdrawal of consent.
- You can view, edit and delete the data stored on your phone in the app at any time, and you can remove all of it at once by deleting the app. Because we do not have this data, we cannot fulfill requests concerning it, and there is no need to.
- For data related to ads you can turn to Google, and you can reset your advertising ID in your phone’s settings.
- For questions and requests you can reach us at hello@nuji.hu.
- For a complaint you can turn to the Hungarian National Authority for Data Protection and Freedom of Information (NAIH) (1055 Budapest, Falk Miksa utca 9-11., postal address: 1363 Budapest, Pf. 9., naih.hu), or to the court of your place of residence.
11. Children
Nuji is not made for children, and it is not listed in the App Store’s Kids category or in Google Play’s family program. We knowingly do not process data about users under 16, and because there is no account, we do not collect personal data regardless of age group.
12. Security
The app’s data sits in storage isolated by the operating system, which other apps cannot access. Its protection depends on the protection of your phone, so we recommend using a screen lock and your phone’s built-in encryption, which is on by default on today’s iPhones and Android phones. Communication with Google and the stores takes place over an encrypted channel.
13. Changes to this policy
If the app’s data processing changes, for example because we add a new service provider, we will update this policy before the change and change the effective date as well. Use of the app is governed by Apple’s Standard License Agreement on iPhone and by the Google Play Terms of Service on Android. If you have questions, you will find help in the help center.
