## Contact the developer

[Send a private message to @brightengkk on X](https://x.com/brightengkk). This is the contact route published on [Sihan Teng’s website](https://me.brighteng.org/about/). An X account may be required to send a message. Use this channel for app support, accessibility issues, and privacy requests; do not post sensitive information in a public reply.

For a bug report, include your Reader version, iPhone or iPad model, iOS or iPadOS version, whether the book is PDF or EPUB, the steps you took, and the error message. A screenshot with personal content hidden can help. Do not send passwords, sign-in codes, account tokens, or a complete book.

## A PDF or EPUB will not import

Use **Import** in the Library and choose a PDF or EPUB from Files. If the file is in a cloud provider, make sure it has downloaded and can be opened. A damaged, protected, or unsupported document may fail to load. Try a known-good file to distinguish a document problem from an app problem. See the [import guide](/guides/import-pdf-epub/).

## ChatGPT will not connect or respond

Open Reader’s Settings and check the AI and Account sections. Complete sign-in on OpenAI’s page, return to Reader, and select a model available to your account. Device-code login must be permitted by your ChatGPT security settings or workspace. Use **Test Connection** to check the chosen model.

An access error can mean the account or selected model is not eligible. A usage-limit error needs to be handled under the provider’s limits. Reader cannot grant an entitlement, bypass a limit, or guarantee that a subscription supports this connection. Do not keep retrying a denied request. See the [ChatGPT reading guide](/guides/chatgpt-reading-assistance/).

## PDF text cannot be selected

A scanned page may be an image without selectable text. Reader’s passage actions need a text selection; the app does not currently advertise built-in OCR. A PDF’s reading order may also differ from its visual layout. Try a PDF with an existing text layer, or obtain an accessible EPUB from the publisher.

## Remove data or disconnect an account

To stop sending reading content to ChatGPT, open **Settings → Privacy & Support → Stop sharing reading content**. This leaves ordinary reading, notes, and bookmarks available. You can review the permission and allow sharing again later.

Use a book’s Delete action in the Library to remove its imported file and library entry. Remove saved notes and bookmarks separately in the Notebook. Use **Disconnect account** in AI settings to remove Reader’s local ChatGPT credentials. Source files, backups, and information already held by a provider are separate. See the [privacy policy’s retention and deletion section](/privacy/#retention-and-deletion).
