Privacy Policy

Last updated: June 22, 2026 · Effective: June 22, 2026

RiceLayer is a browser extension that restyles the appearance of the webpage you are looking at using CSS only. Our core promise: we change how a website looks, never how it works, and never by reading your private data.

1. Who we are

This policy describes how the RiceLayer browser extension and its supporting backend service handle information. If you have any questions, contact us at cimmonster1@gmail.com.

2. What we do and don't access

3. Information processed

Processed locally in your browser (never leaves your device on its own)

To restyle a page, RiceLayer reads the page's structure: element counts, detected structural roles (such as navigation, cards, forms), the existing color palette, a typography summary, and layout density. This analysis happens entirely in your browser and is not transmitted unless you explicitly request an AI-generated theme (see below).

Stored locally via chrome.storage

Your preferences — selected presets, per-site theme settings, saved themes, and whether a theme should auto-reapply on a given site — are stored locally in your browser. You can delete them at any time from the extension's Options page or by removing the extension. This data is not sent to us.

Sent to our backend only when you request an AI theme

When (and only when) you ask RiceLayer to generate a theme from a text prompt, it sends a minimized, value-free summary of the current page to our backend so a theme can be generated. Specifically:

• The site hostname (e.g. example.com)
• A page-category guess
• Element counts and detected structural roles
• An existing color / typography / layout summary
• Safety flags — whether password, payment, or other sensitive form fields are present (a true/false signal only, never their contents)
• Your short text prompt (up to 50 characters)

4. How information is used

We do not use any information for advertising, profiling, creditworthiness, or any purpose unrelated to restyling the page you chose.

5. Third-party services

To produce AI-generated themes, our backend sends the value-free structural summary and your prompt to Google's Gemini API, which returns theme data as strict JSON / CSS only. Your use of this feature is subject to Google's Privacy Policy. The AI provider's API key is read only on our server from its environment and is never exposed to the browser. We do not use any other analytics, advertising, or tracking third parties.

6. Permissions and why they are needed

RiceLayer does not load or execute remote JavaScript, WebAssembly, or other remote code. All executable logic ships inside the extension package; the backend returns only CSS theme data, which is sanitized before use.

7. Data retention

Preferences and saved themes remain in your browser until you delete them or remove the extension. Structural summaries sent for AI generation are used to fulfill the request and are not used to build user profiles. We do not maintain user accounts.

8. Security

Page analysis is value-free by design, requests are transmitted over HTTPS, and theme CSS is sanitized at multiple layers (server and extension) before it is ever applied. Sensitive pages such as banking, login, and checkout are treated cautiously and protected by default.

9. Children's privacy

RiceLayer is not directed to children under 13 and does not knowingly collect personal information from them.

10. Your choices and controls

• CSS-only transformations with a one-click reset on every page.
• Per-site enable/disable and a global on/off switch.
• Delete any saved theme or all stored data from the Options page.
• Uninstalling the extension removes all locally stored data.

11. Changes to this policy

We may update this policy from time to time. Material changes will be reflected by updating the "Last updated" date above.
