Nibbud Privacy Policy

Effective date: 10 October 2026

Last updated: 10 October 2026

1. About this policy

Nibbud helps children explore letters, numbers, handwriting, listening activities, and stories.

This Privacy Policy explains how information is handled when you use the Nibbud mobile app or contact us for support. It is written for parents, legal guardians, and other adults responsible for a child’s use of the app.

Nibbud is operated by Huy Nguyen, based in Viet Nam (“we,” “us,” or “our”). You can contact us at nibbud.com.

2. Information stored on your device

Nibbud works without a Nibbud account. The app stores information on your device so it can remember your preferences and learning progress.

This information includes:

• An optional name or nickname, an age value, and a selected illustrated avatar.
• Language, sound, and narration preferences.
• Completed lessons and stories, the last selected lesson, and dates on which learning rewards were earned.
• Your arrangement of stickers in the reward garden.

A child’s real name is not required. You may leave the name blank or use a nickname. The age field is a local profile setting, not a request for a date of birth or proof of identity.

The app also processes touch movements and activity responses on your device to provide immediate learning feedback. Unfinished tracing and activity state may be held temporarily during an app session.

Nibbud does not upload this profile information, learning progress, or tracing activity to us. We cannot remotely view or retrieve it.

3. Advertising, tracking, and device permissions

Nibbud does not display advertisements or include third-party advertising, behavioral analytics, or crash-reporting SDKs. We do not use advertising identifiers to track children or build advertising profiles.

The app does not request access to your camera, microphone, contacts, photo library, or precise location. Narration plays audio; it does not record your child’s voice.

We do not sell or rent personal information, or share it for targeted advertising.

4. Device services and backups

Some features depend on services supplied by your device or operating system.

Narration. Nibbud passes lesson text to your device’s text-to-speech service. Available languages, voice quality, and whether speech requires a network connection depend on the selected voice, speech engine, and device settings. Nibbud does not send your child’s profile or learning history as part of a narration request. You can disable narration in the app’s settings.

Backups. Nibbud does not provide its own cloud account or progress synchronization service. However, your operating system may include app data in a device backup or device transfer, depending on your settings. Those copies are managed through the relevant device or backup provider.

App stores and diagnostics. Apple or Google may process information when you download, update, or purchase an app, or enable platform diagnostics. We may receive store reports or diagnostic information made available through their developer services, depending on your settings and the platform’s practices. This is separate from Nibbud uploading your local learning records.

These services are subject to their providers’ privacy policies and controls.

5. Information you send when contacting us

If you contact us, we receive your email address and the information you choose to include, such as a description of a problem, your device model, or an attachment.

We use this information to answer your request, troubleshoot problems, and maintain relevant support records. Please avoid sending a child’s full name, photographs, voice recordings, or other unnecessary personal information. Remove personal details from screenshots before sending them.

Our email or support service providers process correspondence to help us handle your request. We may also disclose relevant information where legally required or necessary to establish, exercise, or defend legal claims.

Contacting support does not subscribe you to marketing messages.

6. Children’s privacy

Nibbud is designed for children, including children under 13. Children can use its learning activities without creating an account or providing personal information to us.

Parents and guardians can choose whether to enter a local nickname and can review or change the profile on the device. The app does not provide public profiles, messaging, or public sharing of children’s work.

If you believe a child has sent personal information directly to us, contact Nibbud. We will review the request and delete information that is unnecessary or that we are required to delete.

If a future feature involves collecting children’s personal information, we will provide the required notices and obtain parental consent where required before that collection begins.

7. Retention and deletion

Local app information remains on your device until it is changed or removed. You can edit the profile in the app, including clearing the optional name.

To remove all local app information, use your device’s app-data deletion controls or delete the app and its associated data. Offloading or archiving an app may preserve its data. Copies in device backups may remain until you remove them through the backup provider’s controls, and restoring a backup may restore app information.

We cannot remotely erase or recover information that exists only on your device.

Support correspondence is kept for as long as reasonably needed to resolve your request and handle related follow-up, unless a longer period is required for legal obligations or a legal dispute. You can ask us to delete correspondence by contacting Nibbud.

8. Your privacy rights

Depending on where you live, you may have rights to access, correct, delete, or receive a copy of personal information we hold about you, restrict or object to certain processing, or withdraw consent where processing relies on consent. You may also have the right to complain to your local data protection authority.

For support correspondence, we process information as necessary to respond to your request and provide support, to pursue our legitimate interest in resolving product issues where applicable, or to meet legal obligations.

To make a request, contact Nibbud. We may ask for limited information to verify the request and will respond within the time required by applicable law.

These requests concern information we actually hold. Your local profile and learning records are managed on your device.

9. Security and international processing

Local app information relies on your device’s security protections. Protect your device with an appropriate passcode and keep its operating system updated.

If you contact us for support, your correspondence may be handled in Viet Nam and in other countries where our email or support providers operate. This is separate from the learning information stored locally in the app. Where applicable law requires safeguards for international transfers, we will use the required safeguards. You can contact us for information about the providers and safeguards relevant to your support request.

No device, storage system, or communication service can be guaranteed completely secure.

10. Changes to this policy

We may update this policy to reflect changes to Nibbud or applicable requirements. We will update the date above and provide appropriate notice of material changes. Where a change requires consent, we will obtain it before beginning the relevant processing.
