Privacy Policy

Your GutC diary is stored on your device. No GutC account is required, and we do not automatically receive or remotely access your entries. We separately receive emails and attachments you choose to send to support.

Information you enter is stored on your device. This includes your name or nickname and goals; medication, weight, meals, hydration, wellbeing, bowel, urine, period, blood pressure, blood glucose and test records; expenses, inventory, insurance notes, contact details and receipt photos. Depending on the features you choose, the app uses it to display records and charts, provide reminders, estimate period dates for reference and create backups.

Connecting Apple Health is optional. GutC displays the weight, waist circumference, BMI, blood pressure, blood glucose and period data you allow it to read. It does not copy this source data into its journal storage, full backups or CSV exports.

If you separately enable and authorize writing, GutC also saves blood pressure and blood glucose entries you make to Apple Health. You can change permissions in device settings. Data remaining in Apple Health after deletion in GutC must be managed separately in the Health app.

Entries made on your Watch are sent to the paired iPhone and kept on the Watch until sent. The Watch also stores settings and summaries needed for schedules and recording. Your full diary and receipt photos are not copied to it. If delivery is delayed, check the iPhone's record list.

Widgets receive only the summaries they need. Medication names and doses are hidden in notifications and widgets by default, but general schedule information may appear. Check the app's detail display options and your device's lock and notification preview settings.

Apple handles payments and account authentication. The app checks access using product details, transaction IDs, purchase and end dates, and refund and renewal status verified by Apple. We do not receive your card number, Apple Account password or verification codes, and health entries are not sent to Apple to verify a subscription.

If you send subscription details such as a transaction ID to support, we can use Apple's official tools to check that GutC transaction and its subscription status. This does not give us access to your Apple Account's full purchase history.

We use the email address, display name, message and attachments you send to info@hedeonix.com, along with our replies, to resolve your request and check errors or subscriptions. We process only what is needed for the support you requested and obtain separate consent where required by law.

Emails opened from the app are prefilled with app and operating-system versions. Optional app diagnostic files contain versions, feature status, errors and processing details; subscription support files contain product details, transaction IDs, purchase and end dates, and related information. Neither file includes health entries, and app diagnostic files also exclude account and transaction IDs.

Drafting an email or creating a file does not send it. You review the contents and choose whether to send them; you can ask for help without a file. Do not send health entries, full backups, passwords or verification codes.

Recovering records after changing devices or reinstalling requires a full backup or CSV file saved beforehand. GutC's health record storage is excluded from whole-device backups such as iCloud backups, so create a backup within GutC before deleting the app or changing devices.

Full backups are encrypted with a password you choose. We do not keep the password or a recovery key and cannot restore access if you forget it. A CSV exported from GutC is an unencrypted file of tabular data. You can import the records it contains back into the app. Use a full backup to transfer photos, your profile and reminder schedules as well.

You choose where to save or share backups, CSV files and photo copies. Deleting records in GutC does not delete copies saved outside the app; delete those separately where they are stored.

Device records are generally kept until you delete them. Delete All removes health records, your profile, medication schedules, widget data and scheduled reminders from this device. Some app settings, such as language, remain unchanged. Deleting the app may cause you to lose your records.

Bowel and urine entries without notes or unusual observations are automatically deleted when you restart the app or save a new bowel or urine entry, once more than 30 days have passed since the recorded date. Entries with notes or unusual observations, entries in the older format, and other records such as weight, medication or periods are excluded from this rule.

Even when you add an old entry or restore a backup, the 30 days are counted from the date recorded in the entry. Export records as CSV before deletion if you want to view them long term.

We promptly delete support emails when they are no longer needed to handle your request. Where the law requires retention, we separately keep only the necessary information from consumer complaints and dispute resolution for three years, and from contracts, statutory cancellations, payments and service delivery for five years, then delete it.

These statutory periods follow Korea's Act on Consumer Protection in Electronic Commerce and Article 6 of its Enforcement Decree. After the retention period, electronic information is deleted in a manner designed to prevent recovery and paper records are shredded. Apple Health data and App Store transactions are managed separately by those services.

The app has no advertising or usage analytics tools. We do not sell health entries or use them for advertising or AI model training.

The informational website has no feature for entering or uploading health entries. Website access information may be processed to operate and secure the site and address technical issues.

You can view, edit, delete and export device records in the app; we cannot open or delete them for you. Viewing, backing up, exporting and deleting remaining records stays available after a subscription ends, subject to the automatic deletion rule in section 8. You can grant or withdraw Apple Health, notification, camera and photo permissions in device settings.

To request access, correction, deletion, restriction of processing or withdrawal of consent for support information you sent us, contact info@hedeonix.com. We verify your identity using only what is necessary and handle your request. If a legal retention requirement or another lawful limit applies, we explain why.

Information stored on the device uses operating-system protection. Only staff handling support can access support material, to the extent needed, and we do not reuse it for health analysis or AI training.

The GutC app does not automatically send users' names or health entries to Hédéonix.

Privacy contact: Hédéonix, represented by Yeonsun Shin, info@hedeonix.com. In Korea, privacy complaints and dispute mediation are also available through the Privacy Infringement Report Center (privacy.kisa.or.kr) and the Personal Information Dispute Mediation Committee (kopico.go.kr).

We announce policy changes and their effective date in the app or on the website. Where separate consent is required, we explain the change and obtain consent first.

Korean is the original language of this policy; Hédéonix's English version is an official translation. If versions from the same revision differ in meaning, the Korean original governs.

Our Korean and English replies to App Store reviews and support requests are official replies. If translations differ, the Korean original provided to you governs; where we replied in English without a Korean original, that English reply governs. Other translations, including automatic translations, are for reference unless separately designated as official or the law provides otherwise.

This language rule does not limit legally required notices, consent or your rights. Please report translation errors to support. We will review them and make any necessary corrections.
