Feed Filter for Reddit

Privacy policy

Last updated 10 November 2026. Feed Filter for Reddit is a browser extension for Chrome and Firefox made by UXL Labs. This page explains what it keeps, what it sends, and how to reach us.

The short version

• Posts and titles never leave your browser.
• No account, no analytics, no tracking.
• Only two things go over the network: the license check with Polar, and for Pro, a one time download of the files for the AI model that runs on your device.

What the extension reads

On your Reddit Home feed, the extension reads each post's title and subreddit name to decide whether the post fits you. This happens inside your browser. The extension sends nothing to Reddit and nothing to us. We do not run a server that receives your data.

What stays in your browser

The extension keeps the following in your browser's local extension storage. We cannot see any of it.

• Your settings: blocked places, blocked title words, blocked subreddits, languages, topics and switches.
• The posts hidden today, with their titles, subreddits and the reason, so the Today view can list them and bring one back.
• In Pro, the examples it learned from your Show and Not for me taps.
• In Pro, your license key and its activation, so Pro stays on.
• In Pro, the AI model files, so they download only once.

What goes over the network

1. The license check with Polar. When you activate a license key, the extension sends Polar (api.polar.sh) the license key, our Polar organization id, and a short label naming your browser, like "Feed Filter: Chrome on Windows", so you can tell your browsers apart in the customer portal. About once a week after that, it sends the license key, our organization id and the activation id to check that the key is still valid. Nothing about your Reddit use is included. Without a license key, no check is made.

2. The model download, Pro only. Smart filtering uses a small AI model that runs on your device. The first time it starts, the extension downloads the model files once from Hugging Face (huggingface.co), about 340 to 400 MB. This is a plain file download: nothing about you or your feed is sent with it. Smart filtering uses your computer's graphics card. When the browser can't use it, Pro runs on your rules and what it learned from your taps.

Like any request from your browser, Polar and Hugging Face receive your IP address and basic browser details when these calls are made. Their own privacy policies cover how they handle that.

Payments

Polar (polar.sh) is the seller and merchant of record for Feed Filter Pro, not Google or Mozilla. When you buy, Polar collects your email address and payment details at checkout and sends your license key by email. We do not receive your card details. You can see your orders and your license key in the Polar customer portal.

No account

You do not sign up or log in to use the extension. We do not ask for your name, and the extension does not collect your email address. The only email address involved is the one you give Polar at checkout.

Deleting your data

• Removing the extension from your browser deletes everything it stored: settings, hidden post lists, learned examples, the license activation and the model files.
• To forget only what it learned and keep your rules, open the popup, go to Status and click Reset.
• To free a browser slot for your license key, remove that browser in the Polar customer portal.
• For the email and order details Polar holds, write to us and we will help, or contact Polar directly.

Children

Feed Filter for Reddit is not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child under 13 has given us personal information, write to us and we will help.

Changes to this page

If we change how the extension handles data, we will update this page and its date.
