Reply Assistant — Privacy

Last updated: 27 September 2026. Developer: HBoot.

What the extension does

Reply Assistant reads the selected social post when you open its panel. It sends the selected text, quoted text, loaded conversation messages and author handles, your optional notes, language preferences and model instructions to your chosen AI provider when you request a translation or reply, or when you open or refresh a conversation with Auto translate enabled. Auto translate is off by default and can be disabled in the panel. Loading available models sends your API key to the configured models endpoint from the settings page, without any post text; this does not automatically save your settings or key. Connection testing sends a short test message, not a social post. Generated replies are never posted automatically.

Where data goes

Requests go directly from the extension to the HTTPS API endpoint you configure, authenticated with your own API key. That provider processes the request under its own policies and may charge API fees. If you use a gateway, that gateway may route your text to downstream model providers. Review their terms before sending sensitive or non-public material. We do not operate a relay server or receive your posts or API keys.

Local storage

Your language and model settings, plus the floating window size, position and column layout and auto-translation preferences, are stored locally in this browser profile. Keys are stored in memory for the browser session by default. If you choose “Remember key on this device”, the key is stored locally on this device. It is not synced by the extension and local storage is not an encrypted vault. Keys are not provided to the page content script. The extension does not persist reading history, post text or replies. Panel contents remain in memory while the panel exists.

Permissions

Access to x.com allows the extension to add its panel and extract the selected post and, on request, loaded messages preceding it in its detail page. Conversation ancestry requires your review; unloaded and collapsed messages are not fetched. Storage saves settings and your chosen key storage preference. Access to the model API domain is requested when you load its models or save its configuration. The extension does not request cookies, browsing history, or permission to publish posts.

Control and deletion

You can review the read-only post, remove or reorder earlier messages, and add notes before generating replies, cancel an in-progress request, and delete settings and keys from the settings page. Cancelling does not retract data already sent to the provider or guarantee reversal of charges. Close the panel to stop using it; uninstalling removes extension storage. Data already sent to a provider is governed by that provider's retention and deletion policies.

Limited use

Data is used only to provide the disclosed reading, translation and reply-assistance features. It is not sold, used for advertising or collected for analytics. Our use of user data adheres to the Chrome Web Store User Data Policy, including its Limited Use requirements.
