Privacy Policy

This policy explains how JJ BROS STUDIO LTD handles information when you use the Ikigai Daily iPhone app, Android app or website. The mobile apps have no user accounts and keep your favourites, creations and preferences locally. The free app experience may show Google AdMob ads. Android 2.0.1 is intended for adults aged 18 or over and does not ask for a date of birth. Google Play availability for Android 2.0.1 is restricted to adults. The earlier Android 2.0 age prompt and settings retained by existing installs are described below. The app stores handle the optional one-time Remove Ads purchase.

1. Who We Are

Ikigai Daily is operated by JJ BROS STUDIO LTD, which is the controller of information it receives directly.

2. Information Stored in the Mobile App Builds

The iPhone and Android apps may store the following on your device so their features work:

• favourite card identifiers;
• custom-card text and design choices, and temporary files created when you save or share a card;
• chosen subjects and card types, language, text size, appearance and onboarding state;
• on existing Android 2.0 installations, the saved age group and, for some under-18 users, the saved date they become eligible as adults. Android 2.0's optional date-of-birth entry was not stored;
• the cards you have already seen, the cards you asked to see less of, and the reading preferences the app works out on your device from your favourites and Show less choices;
• counters that space out full-screen ads and the occasional card for our own Documni app;
• reminder frequency, scheduled card identifiers and notification settings;
• wallpaper and widget preferences; and
• a local flag recording that the store has confirmed Remove Ads.

iOS uses Apple storage such as UserDefaults and app-group storage; Android uses private app storage such as SharedPreferences. We do not operate a server that receives this information. Notifications are scheduled locally and can be changed in the app or device settings. The apps do not request your contacts or precise location and do not ask for your name or email address.

Device and cloud backups

If device backup is enabled, Apple or Google may include some private app data in an iCloud, Android or other device backup. A backup may restore that information when you reinstall the app or set up another device. Those backups are controlled by your platform account and provider; JJ BROS STUDIO LTD cannot view or delete them. To remove backup copies as well as the live app data, manage the relevant device backup in your Apple or Google account settings.

3. Advertising in the Free Mobile App Builds

Android 2.0.1 is intended for adults aged 18 or over and does not ask for or collect a date of birth. Google Play availability for Android 2.0.1 is restricted to adults. The earlier Android 2.0 release asked an optional date-of-birth question to decide whether to show ads; it did not store the date entered. It kept the resulting age group on the device and, for some under-18 users, the date they become eligible as adults. On existing Android 2.0 installs, a saved under-18 status remains ad-free until its saved adult-eligibility date, and a saved unknown-age status remains ad-free. Adults who have not bought Remove Ads may see ads, subject to the consent choices required in their region. This describes Android 2.0.1 and earlier Android 2.0 behavior, not the iPhone app or other Android builds.

The free iPhone and Android apps use the Google Mobile Ads SDK (AdMob) and Google's User Messaging Platform. Google and participating ad partners may automatically collect or share the following data for advertising, measurement, analytics, security and fraud prevention:

We receive aggregated advertising and revenue reports. We do not send Google the content of your favourites, custom cards, reminder topics or wallpaper choices. Google says Mobile Ads SDK data is encrypted in transit. Its exact processing can depend on your device, consent, region, SDK version and the ad that is served.

In the UK, EEA and other regions where required, the app presents Google's consent choices before requesting production ads. You can refuse personalised advertising and still use the free content; you may instead receive non-personalised, contextual or limited ads. On iOS, cross-app tracking and IDFA access also depend on the App Tracking Transparency choice. Where Google requires an in-app privacy options entry point, it appears in Settings. Device-level ad and tracking controls remain available in iOS or Android settings.

A verified one-time Remove Ads purchase stops the app from requesting and displaying AdMob ads. It does not erase data Google or an ad partner processed earlier. Learn more in the Google Privacy Policy, Google advertising information and Google's privacy controls.

4. App Store and Google Play Billing

Remove Ads is a one-time, non-subscription purchase. Apple processes iOS purchases through the App Store and Google processes Android purchases through Google Play. The relevant store handles your store account, payment method, billing address, purchase history, refunds and payment security under its own terms and privacy policy. We do not receive your full card or bank details.

The app asks the store for product pricing and purchase or entitlement status so it can complete or restore Remove Ads. We may receive store-provided transaction, entitlement and aggregated sales records for fulfilment, accounting, fraud prevention and support. A local entitlement flag is retained on the device; the store keeps its own purchase record according to its retention rules.

5. Card Information and External Links

The text on every card, including the story shown when you tap Info, is built into the app. Opening Info does not contact Wikipedia or any other service, and we do not send your reading activity to anyone. Your cards work offline; the apps use the network only for advertising and consent (section 3) and the app store (section 4).

Some links open outside the app, and only when you tap them: Read more on Wikipedia, a picture's source or licence, and, for readers with ads, the occasional card for our own Documni app, which opens documni.com. Your device opens the page in your browser or another app it chooses. That site receives ordinary connection information, such as your IP address and the page you asked for, under its own privacy policy; for Wikipedia this is the Wikimedia Privacy Policy.

6. The Website

The website at ikigaidaily.app has no user accounts. If you choose a language, the site stores that choice in a first-party cookie so it can open the same language next time. The value remains in your browser and is not used for advertising or audience measurement. You can remove it by clearing site data for ikigaidaily.app.

Our hosting, content-delivery and security providers necessarily process technical request data such as IP address, requested URL, date and time, browser or user-agent information, response status and security signals. This is used to deliver the site, prevent abuse, diagnose failures and maintain security.

We use Google AdSense to support the website through advertising. Google and its advertising partners may process your IP address, browser and device information, pages visited and interactions with ads. They may use cookies or other local storage to deliver and measure ads, prevent fraud and, where permitted by your choices, personalise advertising. See how Google uses information from sites that use its services.

Google and other advertising partners may use advertising cookies to serve ads based on your earlier visits to this or other websites. You can turn off personalised advertising in Google My Ad Center. Google's partner information linked above explains these services; some third-party advertising providers also offer their own controls through YourAdChoices.

Google's privacy message provides advertising choices where applicable, including for visitors in the EEA, UK and Switzerland. You can change or withdraw consent using the privacy and cookie settings link provided by that message. Declining consent does not prevent you from reading our public content. Non-personalised or limited ads may still appear, depending on your region and choices. We do not currently load a separate audience-measurement service.

Selecting an email link opens your email provider; the website does not contain an Ikigai Daily contact-account form. If you email us, we receive the address, message and attachments you choose to send. External links, including Wikipedia and app-store links, are governed by the destination provider's privacy policy.

7. Why We Use Information

Depending on the information and where you live, we rely on:

• performance of a contract or steps you request, such as delivering and restoring Remove Ads;
• consent for personalised advertising, tracking or optional audience measurement where consent is required;
• legitimate interests in operating, securing, improving and supporting the apps and website, provided those interests are not overridden by your rights; and
• compliance with tax, accounting and other legal obligations.

You may withdraw consent through the in-app privacy options, iOS or Android settings or by clearing browser site data. Withdrawal does not affect processing that was lawful before it.

8. Sharing and International Processing

We use information only as described in this policy. Relevant data may be processed by Google and its ad partners, Apple, Google Play, and website hosting or security providers. Wikipedia and other linked sites receive information only when you open one of their pages yourself. We may also disclose limited information if required by law, to protect people or the service, or as part of a corporate transaction subject to appropriate safeguards.

We do not sell your favourites, custom cards or support details for money. Some privacy laws use "sale" or "sharing" broadly for personalised advertising; the consent and device controls described above let you refuse that advertising where applicable. Providers may process information outside the UK or your country under their legal transfer mechanisms.

9. Retention and Deletion

• Mobile-app data remains locally until you remove items, clear app storage or delete the app. A platform backup can retain a copy until you manage or delete that backup.
• The website language preference remains until you clear the browser's site data, it expires or the browser removes it.
• Support correspondence is kept only as long as reasonably needed to answer the request, maintain a support record, resolve disputes and meet legal obligations, then deleted or anonymised.
• Transaction and accounting records are kept for the period required by tax, accounting, fraud-prevention and legal rules.
• Security logs are retained for the period reasonably needed to operate and protect the site, subject to the hosting provider's retention settings.

Google, Apple and Google Play set their own retention periods for data they control, and so do sites you open from a link. Full local and third-party deletion options are explained on the Data & Deletion page.

10. Your Privacy Rights

Depending on your location, you may have rights to access, correct, delete or receive a copy of personal information, restrict or object to processing, and withdraw consent. You may also complain to your local data-protection authority. In the UK, this is the Information Commissioner's Office.

Because there are no Ikigai Daily accounts and local app/browser data is not sent to us, we usually cannot identify or retrieve it. You can act on it directly using our deletion guide. For information held by JJ BROS STUDIO LTD, such as a support email, contact us. We may need enough information to verify and locate the request. Requests about data controlled by Google, an app store, a site you opened from a link or a backup provider should be made through that provider's privacy tools.

11. Security

We minimise the information we receive, use platform-private storage for mobile-app preferences, use HTTPS for network traffic under our control, and limit access to support and operational information. Providers such as Google state that their Mobile Ads SDK encrypts data in transit. No device, transmission or storage system can be guaranteed completely secure, so we review safeguards as the service changes.

12. Children

Ikigai Daily has no user accounts and does not ask children for a name, email address or precise location. Android 2.0.1 is intended for adults aged 18 or over, does not ask for a date of birth, and has Google Play availability restricted to adults. The earlier Android 2.0 release asked an optional date-of-birth question for ad eligibility but did not store the date entered. Existing Android 2.0 installs may retain the resulting age group and, for some under-18 users, an adult-eligibility date. Saved under-18 status remains ad-free until that date; saved unknown-age status remains ad-free. If a parent or guardian believes a child sent personal information in a support message, contact us so we can investigate and delete it where appropriate.

13. Changes and Contact

We may update this policy when the apps, website, providers or legal requirements change. The current version and revision date will remain at ikigaidaily.app/privacy.

Questions or privacy requests can be sent to ikigai@jjbrosstudio.com. You can also read our Terms of Use and Data & Deletion guide.
