ThreadLens — Privacy Policy

Last updated: July 23, 2026

ThreadLens ("the extension", "we", "our") is a Chrome extension that provides a better way to browse Reddit — multi-subreddit feeds, bookmarks, Hot/New/Rising/Top sorts, and post search. This page explains what data the extension accesses, how it is used, and what is (and is not) collected or transmitted.

In short: ThreadLens does not have a backend server. It does not collect, store, or transmit any personal data to us or to any third party. All settings and saved data stay on your device. The only network requests it makes are directly from your browser to Reddit's public API and to ExtPay for optional PRO payment processing.

1. Data the extension accesses

To display Reddit feeds, the extension reads publicly available data from Reddit's JSON API when you use it on reddit.com:

Public thread listings (titles, scores, comments, subreddits)
Post URLs and metadata

This is public Reddit content — the same data available by visiting Reddit's website directly. The extension does not access your Reddit account, read private messages, or interact with logged-in sessions.

2. Data stored locally on your device

The extension uses Chrome's built-in chrome.storage.local API to remember your preferences between sessions. This data is stored locally in your browser profile and is never sent to us or to any third party.

Data	Purpose
Saved subreddits and multi-reddit configurations	Remember your customized feed sources
Bookmarked posts (URL, title, subreddit)	Let you save and revisit posts later
Trial start timestamp (`trialStartedAt`)	Track your 15-day PRO trial locally
PRO payment cache (`extpayPaidCache`)	Cache your PRO status after payment via ExtPay
Cached Reddit feed data	Provide faster load times; automatically refreshed 4x per day

You can clear this data at any time by removing the extension, or by clearing its storage from chrome://extensions.

3. Network requests

The extension communicates with the following external services over HTTPS:

Endpoint	Purpose
`reddit.com/*`	Fetch public Reddit thread listings and post data
`old.reddit.com/*`	Alternative Reddit interface for fetching the same data
`extensionpay.com/*`	Process optional PRO payments via ExtPay

Reddit requests use the same public JSON endpoints that Reddit's own website uses. ExtPay is a third-party payment processor — when you choose to purchase PRO, your payment is handled entirely by ExtPay and its payment partners (Stripe).

4. ExtPay (PRO payments)

ThreadLens offers an optional PRO upgrade through ExtPay, a payment service for browser extensions. When you click "Get PRO":

You are redirected to ExtPay's checkout page hosted at extensionpay.com
ExtPay may collect your email address and payment information to process the transaction
ThreadLens does not see, store, or transmit your payment details
After successful payment, ExtPay notifies the extension of your paid status, which is cached locally as described in Section 2

ExtPay's own privacy policy governs how they handle your payment data. You can review it at extensionpay.com/privacy.

5. What we do not do

We do not operate a server, database, or analytics service of any kind.
We do not collect names, emails, IP addresses, or any other personally identifiable information.
We do not sell, rent, or share any data with third parties — there is no data to share.
We do not use tracking pixels, fingerprinting, or advertising SDKs.
We do not access browsing activity on any site other than reddit.com and extensionpay.com (for payment processing).

6. Permissions

The extension requests the following Chrome permissions, each used strictly for the purpose below:

Permission	Why it's needed
`storage`	Save your settings, bookmarks, PRO trial status, and feed cache locally, as described in Section 2
`sidePanel`	Display Reddit feeds in Chrome's side panel
`alarms`	Schedule periodic cache refresh (4x/day) and cleanup tasks
Host access to `reddit.com` / `old.reddit.com`	Fetch public Reddit thread data
Host access to `extensionpay.com`	Process optional PRO payments (content script injection)

7. Children's privacy

ThreadLens is not directed at children and does not knowingly collect data from anyone, regardless of age, since it does not collect personal data from any user.

8. Changes to this policy

If this policy changes, the "Last updated" date at the top of this page will be revised accordingly. Continued use of the extension after changes are posted constitutes acceptance of the updated policy.

9. Contact

Questions about this policy or the extension's data handling can be sent to this email.
