1. Overview

PikuZen AI is a Chrome extension that helps users generate AI-powered replies on Twitter/X. We are committed to protecting your privacy and being transparent about our data practices.

Key Point: PikuZen AI does NOT collect, store, or sell any personal data. All AI processing happens locally in your browser. The only external call is license key verification via Gumroad's official API for Pro subscription management.

PikuZen AI does not collect any of the following:

3. Data Processing

The extension processes the following data locally in your browser only:

4. Third-Party AI Services

When you use PikuZen AI, tweet content is sent to your chosen AI provider through their web interface embedded in the extension's side panel. These services have their own privacy policies:

Important: PikuZen AI does NOT operate its own servers. AI requests go directly from your browser to your chosen AI provider's website. The only external API call we make is to Gumroad for license verification.

5. Subscription & License Verification

PikuZen AI offers a Pro subscription activated via a license key purchased from Gumroad. When you enter a license key, the following data is sent to Gumroad's official API (api.gumroad.com):

No personal information (name, email, payment details) is sent by the extension. Gumroad returns only the license validity status and purchase date. This verification happens once daily for active Pro users.

Required to inject the PikuZen AI Reply button onto the Twitter timeline and to extract tweet text/context from the page DOM when you click it.

"storage"

Both chrome.storage.local and chrome.storage.sync are used to persist your custom tone prompts, selected AI providers, UI preferences, and subscription status across sessions.

"tabs"

Required for the background Service Worker to manage AI provider tabs (Gemini uses managed tabs) and to relay tweet data via secure chrome.runtime.sendMessage protocols.

"declarativeNetRequest"

Routing headers are modified exclusively to bypass restrictive X-Frame-Options and Content-Security-Policy blocks, enabling the secure loading of AI provider websites inside the extension's embedded iframes.
