HanziHeart is an app brand/trading name operated by Gladiolus Limited.

For HanziHeart account, app, subscription, or technical support, contact hanziheart-support@gladiolus.dev.

Subscriptions

HanziHeart subscriptions are managed through the app store account used for purchase. Subscription price, renewal period, free-trial details, and cancellation information are shown before purchase in the app and by the relevant app store.

iOS: Open Settings, tap your name, tap Subscriptions, select HanziHeart, then manage or cancel the subscription. You can also use the App Store account screen to manage subscriptions.

Android: Open Google Play, tap your profile icon, choose Payments & subscriptions, then Subscriptions, and select HanziHeart to manage or cancel.

Refunds: App store refund requests are handled by Apple or Google under their own refund policies. HanziHeart support can investigate account, access, or restore-purchase issues, but app store billing and refund decisions are normally handled by the relevant app store.

If restore purchases does not behave as expected, include your HanziHeart account email, app version, device model, app store platform, and approximate purchase time when contacting support. Do not send payment card details.

Helpful official links: manage Apple subscriptions, request an Apple refund, manage Google Play subscriptions, and request a Google Play refund.

Affiliate Codes and Friend Invites

Creator affiliate codes identify the creator who introduced a new customer to HanziHeart and must be claimed within the new account’s first seven days, before any subscription. An eligible new customer receives one free month through Apple; the creator receives attribution and any separately agreed commission, not an Apple free-month reward. Friend referral codes begin with HH-. They give the invited friend the same one-month offer and let the inviter earn one free month after Apple confirms the friend’s qualifying subscription.

Friend referrals are available only from active paid Apple App Store subscribers. The invited friend must use a new HanziHeart account, must not previously have held a subscription, and must claim the referral within seven days of creating it. Each new account can claim one friend referral, and each inviter can receive credit for up to 10 friends who start qualifying invited subscriptions in a rolling 365-day period. Uncompleted claims do not consume this reward limit. Apple’s offer eligibility, storefront, redemption, expiry, and subscription conditions also apply.

If an invite link does not work

If HanziHeart is already installed, open the original link again. It should open the app and retain the code.
If you installed from the landing page, copy the displayed code and enter it in HanziHeart during onboarding or from the code-redemption area.
Check the code type: creator links use aff; friend links use ref, and friend codes begin with HH-.
Make sure the invited friend is signed into the intended HanziHeart account and Apple App Store account and that the HanziHeart account was created within the last seven days.
For a creator code, continue to Apple when prompted to redeem the reserved one-month offer. If the offer is still being prepared, retry the same creator code later.
If Apple rejects an offer, check the storefront, offer eligibility, expiry, and subscription state shown by Apple. One-time Apple offer codes cannot be reused.
If the inviter’s reward is pending, allow time for Apple and the subscription service to confirm the friend’s subscription, then reopen the referral screen.

If the problem continues, email hanziheart-support@gladiolus.dev with your HanziHeart account email, the referral or affiliate code, the approximate claim time, and the error shown. Do not send passwords, payment-card details, or another participant’s personal information.

See the Terms of Use for the complete programme rules and the Privacy Policy for information about referral data.

Account and Data Deletion

You can ask us to delete or anonymise personal data associated with your HanziHeart account, subject to legal, security, fraud-prevention, backup, tax, accounting, dispute-resolution, and app-store transaction requirements.

If an in-app deletion option is available in your version of HanziHeart, you can use that option from the account or settings area. If you cannot access the app, cannot find the in-app option, or prefer to request deletion outside the app, email hanziheart-privacy@gladiolus.dev using the email address linked to your HanziHeart account where possible.

Please include the email address used for your HanziHeart account, the sign-in method you used, whether you want account deletion or only deletion of specific app data, and any support ticket reference if you previously contacted us.

Do not send payment card details, passwords, unnecessary identity documents, or unrelated private messages. We may need to verify that the requester controls the relevant HanziHeart account before deleting data.

We aim to delete or anonymise account-controlled data within 30 days of verifying a valid deletion request, unless we need more time or must retain limited information for legal, security, fraud-prevention, backup, tax, accounting, dispute-resolution, or app-store transaction reasons.

Imported screenshots are read on your device and are not uploaded, so there is no screenshot image for us to delete from our systems. App data stored only on your device is removed when you delete the app or clear its data on your device.

Deleting a HanziHeart account does not automatically cancel an Apple App Store or Google Play subscription. You must cancel subscriptions through the app-store account used for purchase.

AI Transparency

HanziHeart uses AI to read the text you submit and to produce the literal meaning, natural meaning, emotional read, tone, and suggested reply. The text you choose to read is sent through our backend to an AI model provider (currently DeepSeek) to generate the result. AI outputs can be wrong, incomplete, or unsuitable for your situation.

Imported screenshots are read on your device and are not uploaded. Always review a read before acting on it, and use your own judgement before sending any suggested reply.
