Jettae Privacy Policy
Effective date 2026-10-12
NodeOnWorks ("we", "us") respects the privacy of children and parents who use Jettae (the "App"), our clock-learning app for children. This policy applies to the App and to our customer support.
At a glance
- The App has no sign-up and does not collect any personal information such as a child's name, age, photo or location.
- Learning progress is stored only on the device and is never sent to our servers.
- We use no third-party tools for advertising, analytics, tracking or crash reporting.
- Payments are processed by Apple and Google. We never receive payment details.
- The only time we receive personal information is when a parent emails our support team.
1. Information handled in the App
a. Information we do not collect
The App does not collect or transmit any information that can identify a user, including names, dates of birth, email addresses, phone numbers, photos, voice, location, contacts or advertising identifiers (IDFA/AAID). The App has no chat, message board or other features that let users communicate with each other.
b. Information stored only on the device
Learning progress, game results, collected stickers and app settings (such as sound and theme) are stored only on the user's device. We cannot access this information, and it is deleted when the App is deleted.
c. Notifications
If the App offers reminders or other notifications, they are local notifications that run entirely on the device and never pass through our servers. You can turn them off at any time in your device settings.
d. In-app purchases
Purchases and purchase restoration are processed by Apple (App Store) or Google (Google Play). We do not receive your name, card number or other payment information; the App only checks, on the device, the purchase status provided by the store. Personal information in the payment process is handled under each store's privacy policy.
e. Statistics provided by the stores
If users have agreed on their device to share data with developers, Apple and Google may provide us with statistics that cannot identify individuals, such as download counts and crash reports. We do not use these statistics to identify anyone, and use them only to improve the App.
2. Personal information handled when you contact support
When a parent emails support@nodeonworks.com, we handle personal information as follows.
| Information | Purpose | Retention |
|---|---|---|
| Email address, name (if provided), message content, attachments, device and app details (if provided) | Responding to your inquiry, purchase and refund guidance, resolving disputes | 3 years after the inquiry is closed, as required by Korean consumer protection law for complaint and dispute records; then deleted without delay |
Please include only what we need to help you. There is no need to send us your child's personal information, such as their name or photo.
3. Children's privacy
Although the App is designed for children, it does not collect children's personal information. Our support is intended for parents. If we learn that a child has contacted us directly, we will not use that information without parental consent, and we will promptly delete anything beyond what is needed to respond.
United States (COPPA): We do not knowingly collect personal information from children under 13. If we become aware that a child has sent us personal information, we will delete it. Parents may contact us at support@nodeonworks.com to review or delete any such information.
4. Sharing with third parties
We do not sell, rent or share your personal information with third parties, except where required by law (for example, a lawful request from a law enforcement authority).
5. Service providers and international transfers
We use the following service to send, receive and store support emails. Its servers are located outside Korea.
| Item | Details |
|---|---|
| Recipient | Google LLC (Google Workspace email) |
| Contact | https://support.google.com/policies |
| Countries | The United States and other countries where Google operates data centers |
| When and how | Transmitted over the network when support emails are sent and received |
| Information | Email address, name (if provided), message content, attachments |
| Purpose | Sending, receiving and storing support emails |
| Retention | Same as Section 2 |
If you do not wish your information to be transferred, you may choose not to contact us by email, although we will then be unable to reply by email.
6. Deletion
When the retention period ends or the purpose has been fulfilled, we delete personal information without delay, using methods that make electronic files unrecoverable.
7. Your rights
You and your child's legal guardian may ask at any time to access, correct, delete or stop the processing of personal information we hold about you or your child. Email support@nodeonworks.com and we will respond without delay, within the period required by law. Learning progress exists only on the device, so it can be removed immediately by deleting the App.
EU/UK (GDPR): We process support emails based on our legitimate interest in responding to your request and, where relevant, to perform our contract with you. You have the right to access, rectify, erase, restrict, port and object to the processing of your data, and to lodge a complaint with the supervisory authority in your country.
Japan (APPI): Support emails are stored on servers of a business located in a foreign country (such as the United States), as described in Section 5. The United States does not have a comprehensive privacy law equivalent to Japan's, but Google LLC maintains appropriate measures to protect personal information.
8. Tracking technologies
The App does not use cookies, advertising identifiers or any other technology to track users.
9. Security
We protect personal information with measures such as two-step verification on our support email account and limiting access to the person responsible for privacy.
