ChatGPT Theme Selector Privacy Policy

ChatGPT Theme Selector is a browser extension that applies user-selected CMDCRL, BUTLER, and GlyphDrift appearance themes to ChatGPT.

Publisher: JMS Effective date: September 6, 2026
ChatGPT Theme Selector stores appearance preferences locally in your browser. It does not collect, transmit, sell, rent, or share ChatGPT conversations, prompts, responses, credentials, or personal data.

Data Collection

ChatGPT Theme Selector does not collect personal data. It does not include analytics, advertising, telemetry, tracking technologies, user accounts, remote logging, or a JMS-operated server.

Access To ChatGPT Pages

The extension runs only on https://chatgpt.com/ pages so it can apply the selected theme to the existing ChatGPT interface. Its GlyphDrift animation may temporarily examine visible response text and its on-screen position to create decorative letter effects. The original ChatGPT content remains in the page and stays controlled by ChatGPT.

The extension does not copy page content into extension storage, retain prompts or responses, send messages, access account credentials, or transmit page content to JMS or any third party.

Local Appearance Preferences

The extension uses the browser's local extension storage to remember whether the theme is enabled, the selected theme and palette, custom colors, named palettes, and the GlyphDrift motion preference. These preferences remain in the local browser profile and are not sent to JMS.

Permissions

The extension requests the storage permission only to save the local appearance preferences described above. Its access to https://chatgpt.com/ is used only to apply the selected appearance and optional visual effects on that site.

Third-Party Services

ChatGPT Theme Selector does not contact external services, load remote code, or use third-party advertising or analytics providers. ChatGPT is a separate service operated by OpenAI and processes activity under its own terms and privacy practices. The extension does not alter how ChatGPT sends or receives that activity.

Data Retention And Deletion

Appearance preferences remain in browser extension storage until you change them, clear the extension's stored data, or uninstall the extension, subject to normal browser behavior. JMS has no remote copy or extension account to delete.

Children's Privacy

ChatGPT Theme Selector is not directed to children and does not knowingly collect personal information from anyone.

Changes To This Policy

JMS may update this policy if the extension's privacy practices change. The effective date above will be updated when material changes are made.
