Haedurok

Privacy policy

Effective date: September 19, 2026

IBRDOS Co., Ltd. ((주)아이비알도스, the “Company”) explains how information is handled by Haedurok. Contact dev@ibrdos.com for privacy questions and rights requests.

1. Records stay on your device

Haedurok records the last date you completed everyday tasks such as cleaning, laundry or replacements and shows the days since. It has no account creation or sign-in. Items and records are not sent to an application server operated by the Company. The Company cannot remotely view or recover your device-local records.

The app stores item names, categories, creation timestamps, completion dates and internal identifiers to manage items, calculate elapsed days and display history. Language and appearance preferences are stored on the device to preserve your choices. You do not need to include your real name, contact details or other personal information in item names.

2. Backup and deletion

Settings lets you export items and records as a JSON file or restore them from a file. A backup contains item names, categories, completion dates, internal identifiers, creation timestamps and the export timestamp. It does not include language or appearance preferences. Backup files are plain text and are not encrypted by the app. Manage access to shared devices and the location where you save a file.

Export uses your operating system’s file sharing interface. If you choose a cloud storage, email or other external service, the backup is sent to that service under its privacy practices. It is not automatically uploaded to the Company. Restore reads the file you select and, after confirmation, replaces all items and records on this device with the backup contents.

You can delete individual records or items, or delete all records in Settings. Deleting an item also deletes its history. Delete all records removes items and records, preserves language and appearance preferences, and cannot be undone. Exported files and copies held by external services are not deleted by the app; manage them separately at their storage location.

Uninstalling the app, deleting app data through the operating system or changing devices may affect device-local data. Operating-system backup and restore features may process app data under the provider’s settings and procedures. Haedurok does not provide account-based synchronization or recovery copies on a Company server.

3. Advertising and privacy choices

Haedurok displays a Google AdMob banner at the bottom of All records using the Google Mobile Ads SDK. Watching an ad or consenting to optional advertising processing is not required to use the recording features.

The advertising service may use IP addresses and approximate location derived from them, ad impressions and responses, app interactions, diagnostics, performance information and app/device-related identifiers for advertising, measurement, analytics and fraud prevention. The Company does not attach item names, categories, completion dates or backup contents to ad requests.

The app requests non-personalized ads. On iOS, it checks Apple’s App Tracking Transparency (ATT) system permission before loading Google UMP or the advertising SDK or requesting ads. With permission, Google advertising services may process device and advertising information to deliver ads and measure their effectiveness. If permission is denied, restricted or unavailable, no ads are requested and the app’s core features remain available. Permission is checked again when returning from system settings. The Android AD_ID permission is removed. Android 13 and later restrict advertising-ID access without this permission; on Android 12L and earlier, advertising-ID processing may depend on operating-system and Google services settings. Non-personalized advertising does not eliminate all advertising SDK data processing after authorization.

Depending on your region and applicable requirements, Google User Messaging Platform (UMP) may show a privacy choice form. Where applicable, the advertising privacy entry in Settings lets you review or change your choices. The app does not request ads when ad requests are not permitted. Recording features remain available.

The advertising SDK sends related information from your device to Google services, and it may be processed outside your country. See the Google Privacy Policy and How Google uses information from apps that use its services for processing and deletion practices. Deleting app records does not delete advertising information already transmitted.

4. Support and external pages

If you contact dev@ibrdos.com, the Company uses your sender email address, message, voluntarily attached files and correspondence to review and respond to your inquiry. Send only information relevant to your request. Do not send passwords, identity documents, payment details or other sensitive information. App records and backup files are not automatically attached to support messages.

The Company deletes inquiry information when the support purpose is complete. Information subject to a legal retention obligation is retained as required by that obligation. You may request access to or deletion of support information at the address above. Uninstalling the app or clearing its records does not delete emails already sent.

Privacy and support documents can be read inside the app. When you open an external link, visit the website or send an email, the relevant website, browser or email provider’s terms apply to those communications. The external storage and sharing services you choose are also subject to their providers’ communications and privacy practices.

5. Permissions and safeguards

The app does not request camera, microphone, contacts, photo-library or GPS location permissions. Backup restore accesses the file you choose through the system file picker. An advertising service’s approximate location inference from an IP address is separate from GPS permission.

The app uses device-local storage and system file selection and sharing features, and validates the format and size of imported data. The Company limits access to support information it receives to those who need it for the support purpose. Use device locks and file-access settings to protect your records and exported backups.

6. Your rights

Contact dev@ibrdos.com to request access, correction, deletion, restriction of processing, withdrawal of consent or other rights provided by applicable law for information held by the Company. A legal guardian or authorized representative may also submit a request. The Company uses the minimum information needed to verify and respond through the applicable procedures. For device-local records the Company does not hold, it can explain how to view or delete them in the app.

For privacy assistance in Korea, contact the KISA Privacy Infringement Report Center or the Personal Information Dispute Mediation Committee.

7. Children and policy changes

Haedurok is not designed or marketed primarily for children. A guardian who believes a child has sent personal information to the Company may contact the address above for deletion or assistance.

Changes to processing practices and their effective date will be communicated in the app or on an information page. A separate consent process applies where required by law.
