Beta use

taihaa is currently a beta product. Features may change, break, or be removed as the app is improved. The beta is provided for testing, learning, and feedback.

Your content

You are responsible for the texts, URLs, translations, notes, vocabulary, source links, and other content you add to taihaa. Do not upload or import content you do not have permission to use.

URL import

URL import is a convenience feature for public article pages. It may fail, extract incomplete text, or return formatting errors. It does not bypass paywalls, login walls, or site restrictions. You should review and edit imported text before saving it as a lesson.

Translation suggestions

Translation suggestions may come from your saved vocabulary, shared user-created dictionary entries, imported dictionaries, or future automated sources. Suggestions may be wrong or incomplete. You are responsible for reviewing and editing saved translations.

Learning features

Segmentation, pinyin, Jyutping, text-to-speech, sentence translations, translation fields, review scheduling, and other learning tools are learning aids. They may be incomplete or incorrect and should not be treated as official language instruction.

Base language

English is currently the only fully supported base language for the v2.0 public beta. Other base-language options may be added later, but they should not be assumed to be fully supported yet.

Taihaa Plus

Reading, saved words, imports and reviews stay free. Taihaa Plus is an optional subscription that raises the daily limits on sentence translations and natural-voice audio, the extras that cost us per use. Free accounts get a small number of each per day, and the count resets every day.

Plus is billed monthly or yearly at the price shown before you pay, and renews automatically at the end of each period until you cancel. A founder year renews at the regular yearly price. You can cancel any time by emailing hello@taihaa.com from your account email; Plus stays on until the end of the period you have paid for, and you will not be charged again. Payments are handled by Stripe. Prices may change for future periods, and we will tell you before a change applies to you.

Plus also has a generous fair-use limit per day to keep the service sustainable. Sentence translations and natural-voice audio are generated automatically and may be wrong or sound unnatural, like the other learning aids below.

Availability

taihaa is provided as-is during the beta. No uninterrupted availability, permanent storage, or error-free operation is guaranteed.

Exports and deletion

You can export your data from the app. Account deletion is available from Settings after a pre-deletion summary, export confirmation, and typed DELETE confirmation. Deletion is intended to be permanent, so you should export anything you want to keep before deleting your account.

Feedback and support

Feedback submitted through the app may be used to fix bugs, handle support requests, improve taihaa, and plan future features. Your submitted support tickets may show their status and admin feedback inside the app.

Misuse

Do not use taihaa to upload, import, or store illegal, harmful, abusive, or unauthorized content. Access may be restricted if the beta is misused.
