Privacy Policy — AdClear

Last updated: 2026-10-21

AdClear ("the extension") hides clearly labeled sponsored and advertising content inside the ChatGPT web interface (chatgpt.com and chat.openai.com). This policy explains exactly what the extension collects, why, where it is stored, and what it never touches.

What AdClear does NOT collect

AdClear does not read, store, or transmit:

• Your ChatGPT conversations, prompts, or responses
• Any page content, text, or images from the sites you visit
• Your browsing history or the list of sites you visit
• Your name, email, account, location, or any login credentials
• Health, financial, or payment information

No page or conversation content ever leaves your browser.

What AdClear collects and why

• Anonymous device identifier: a random UUID generated on your device the first time the extension runs. It is not derived from hardware, IP, or a browser fingerprint, and cannot be linked to your identity or ChatGPT account. Sent to our backend to count distinct users and bind an optional Pro license.
• Usage counts: a daily tally of how many ad cards the extension hid — an aggregate number, not a record of what you saw or did. Sent to our backend to understand usage and prioritize improvements.
• Feedback you submit: only if you use the in-extension feedback form — an optional "is it working?" yes/no and any message you type. Sent to our backend so the developer can fix issues and plan features.
• Pro license token: if you choose to activate Pro, the token you paste and your device ID are sent to validate and bind the license. Payment happens in Telegram (Telegram Stars); the extension never receives or stores card or bank details.
• Settings and local count: your toggles and the local hidden-ad count are stored in your browser only and are never uploaded.

Where data goes / who it's shared with

Supabase (our database backend) is the only party the data above is sent to — the sole backend for usage counts, feedback, and Pro license validation. Nothing is sent to any other third party. There is no advertising, tracking, or sale of data, and no remote code is loaded — all code ships in the extension package.

Data retention & deletion

Local data (settings, count) stays in your browser until you clear it or uninstall. Anonymous counts and feedback are retained in Supabase to track long-term trends. Because the device ID is random and not tied to your identity, we cannot look you up by name; to delete records associated with your device ID, send it to us (see Contact) and we will remove them.

Permissions

The extension requests only what it needs: local storage (settings, count, trial/license state), access to the active tab for popup actions, periodic alarms (to flush the anonymous count and re-check a Pro license), and network access to the ChatGPT domains (where ads are hidden) and our Supabase backend (counts, feedback, license validation).
