Privacy Policy
Last updated: September 28, 2026
ChunkIt ("we", "us", "our") is an English learning app made by Hagen Creative to help students prepare for the English examination with stories, vocabulary and flashcards. This policy explains what information we collect, why we collect it, and the choices you have. By using ChunkIt, you agree to this policy.
1. Information we collect
Account information. When you create an account we collect:
- Your email address and a securely hashed password (email sign-up), or
- Your Google or Apple account ID and the email address they share with us (Google / Apple sign-in).
- The username and nickname you choose.
Learning progress. So your progress is saved and synced across devices, we store:
- Stories you have completed and game results.
- Flashcard review history and schedule.
- Words you bookmark and your review list.
Purchases. If you buy Premium, payment is handled entirely by the Apple App Store or Google Play. We never see or store your card details. We only receive and keep the purchase record (product, transaction ID, expiry date) needed to unlock Premium for you.
Invites. If you use or share an invite code, we record which accounts are linked by that code so both sides receive their bonus.
Help & feedback. If you send us feedback or report a problem, we receive:
- Your message and any details you choose (such as the word or story concerned).
- A screenshot, only if you choose to attach one from your photo library.
- A reply email address, only if you enter one.
- Your device model, operating system and app version, to help us fix the problem.
Basic usage data. We record simple events such as when the Premium screen is opened or a purchase is started, together with an install ID and, if you are signed in, your account, to understand how the app is used and fix problems.
2. Information that stays on your device
- The word and story database used for offline learning.
- Pronunciation audio, which is generated by your device's built-in text-to-speech.
- Study reminders, which are scheduled locally on your device. You can turn them off in your device settings at any time.
3. How we use your information
- To create and secure your account and let you sign in.
- To save and sync your learning progress.
- To verify purchases and provide Premium features.
- To send account emails, such as sign-up verification codes.
- To improve the app and fix bugs.
We do not sell your personal information, and we do not show third-party ads.
4. Sharing with others
We only share information with services that help us run ChunkIt:
- Apple and Google, for sign-in and in-app purchases.
- Our hosting and email providers, which store data and deliver emails on our behalf.
We may also disclose information if required by law.
5. How long we keep it
We keep your information for as long as your account exists. You can delete your account in the app at any time (Profile > Account > Delete account). When you do, we permanently delete your account, sign-in details, learning progress, purchase records and any feedback you sent while signed in. Basic usage events are kept only without any link to you. Apple and Google keep their own records of your purchases under their own privacy policies. See how to delete your account for all the options, including by email.
6. Your rights and choices
You can ask us to access, correct or delete your personal information, or to delete your account, at any time by emailing us at the address below. We will respond within a reasonable time. These rights are provided under Taiwan's Personal Data Protection Act.
7. Security
Passwords are stored only as secure hashes, and access to our servers is restricted. No system is 100% secure, but we work hard to protect your information.
8. Students under 18
ChunkIt is designed for high school students. If you are under 18, please use the app with the knowledge of a parent or guardian. Parents who believe their child has given us information they should not have may contact us and we will delete it.
9. Changes to this policy
We may update this policy from time to time. When we do, we will change the "Last updated" date above. Significant changes will also be announced in the app.
