Lurkbell Privacy Policy
Last updated: 5 October 2026
Lurkbell is a browser extension that notifies you about new Reddit posts matching filters you set. It is published by the independent developer of Lurkbell ("we"). This policy explains what data the extension handles, where it goes, and the choices you have.
The short version: your watches, settings, inbox and API keys stay in your browser. We have no account system and never see what you watch or read. The only data that reaches us is a license key if you buy Pro, and anonymous usage counts, which you can turn off.
1. Data stored only in your browser
The following is kept in your browser's extension storage and is never sent to us:
- Your watches: subreddits, keywords, filters and AI criteria.
- Your settings, including AI provider API keys and webhook addresses for Discord, Telegram or Slack.
- Your inbox of matched posts and their read state.
Uninstalling the extension deletes all of it. You can also erase it at any time with Advanced → Reset.
2. Reddit
Lurkbell reads Reddit through the session you are already logged in with in this browser. It requests listings of the subreddits you watch, checks whether you are logged in, and looks up subreddit names while you type. These requests go directly from your browser to www.reddit.com, as when you browse Reddit yourself. They are covered by Reddit's privacy policy.
Lurkbell never sees or stores your Reddit password. It does not post, comment, vote or send messages.
3. Services you choose to connect
These only happen if you turn them on. The data goes directly from your browser to the service you picked, never through us.
| Feature | What is sent | Sent to |
|---|---|---|
| AI filter (Pro) | Your criteria, plus the title and text of new posts that passed your other filters. Your API key authenticates the request. | The provider you chose: Anthropic, OpenAI, or an OpenAI-compatible address you entered. Its own privacy terms apply. |
| Discord, Telegram, Slack (Pro) | For each match: post title, link, subreddit and watch name. Discord messages also include the author's username and the first 200 characters of the post. | The webhook or bot you configured. |
The browser asks for your permission before Lurkbell may contact any of these services.
4. Data that reaches us
License keys (if you buy Pro)
Purchases are handled by our payment provider, Creem, which acts as merchant of record and processes your payment and email address. We do not receive your card details.
When you activate a key, the extension sends three things to our license server: the key, an activation id, and an activation label such as "Lurkbell · Chrome · 2026-10-05". It sends them again about once a week to confirm the key is still valid. The server forwards them to Creem and does not keep them.
Anonymous usage counts
To learn which features get used and where people get stuck, the extension sends a small event when certain things happen:
- Install, and finishing setup.
- Creating the first watch, and receiving the first alert.
- Starting a trial, clicking buy, and activating a key.
- At most once a day, a note that the extension is in use.
Each event contains only:
- A random id created on install and not linked to you.
- The event name.
- The extension version.
- Your plan (Free or Pro).
- Your browser's language.
Our hosting provider adds the country of the connection. We do not store IP addresses.
Events never contain subreddits, keywords, posts, Reddit usernames, settings or API keys. You can turn usage counts off in Advanced → Send anonymous usage counts. Counts are kept for up to 3 months.
Our license server and usage counting run on Cloudflare, which processes the connection as our infrastructure provider.
This website
This website is hosted on Cloudflare Pages. It sets no cookies and runs no analytics. Clicking "Buy Pro" sends a request to our server to open a Creem checkout; nothing about you is included.
5. What we don't do
- We don't sell, rent or share your data.
- We don't show ads or track you across websites.
- We don't read pages other than Reddit and the services you connect.
- We don't use your data for credit or lending decisions.
The use of information received by Lurkbell adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements.
6. Your choices
- Turn off usage counts in Advanced.
- Turn off the AI filter or any webhook at any time. Their stored keys stay in your browser until you remove them.
- Deactivate a license key on the Plan page.
- Erase everything with Advanced → Reset, or by uninstalling.
The usage counts can't be tied to a person, so we can't single out or export an individual's counts. For anything about your purchase, contact us or Creem.
7. Children
Lurkbell is not directed to children under 16, and we do not knowingly collect data from them.
8. Changes
If this policy changes, we will update the date above. If the change is significant, the extension's release notes will say so.
