About Leftist Solidarity

Leftist Solidarity is a political education and community project focused on making leftist ideas accessible, helping people connect with organizations, and supporting constructive conversation and connection.

About The Creator

I created the facebook group Leftist Solidarity Group about 6 years ago now (around 2020) to have a safe space for all types of leftists to have constructive conversation and community. Now in 2026, I have created this site to provide a leftist-focused social media and resource for learning about different leftist ideologies and finding organizations. If you have any suggestions for the site such as updates or revisions to the learn pages, organizations to add, or requests for the functionality of the social media part of the site, please feel free to contact me and let me know.

I am building this as a single developer while caring for a newborn. If this project helps you, your support helps keep development going.

Content Policy & Moderation Guidelines

New members have post approval turned on until they have three approved posts. After three approved posts, members can post without waiting for approval unless moderation becomes necessary again.

1. Solidarity

   Unlike other social media sites, Leftbook does not reward disruptive, divisive, or edgy content. Solidarity is the main goal and focus here. If you continually spread hate and/or refuse to be open-minded and have productive conversation, I may consider muting or banning.

2. No outspoken “centrists” or “right-wingers”

   This is a left-wing site meant to bring people together through constructive conversation. I acknowledge some who join are not left-wing; if that is you, be humble and open-minded, and do not assert unwanted opinions.

3. No advocating plans of attack

   This site is not for planning or advocating any form of attack, online or in real life. The focus is leftism and solidarity: unifying and spreading our cause.

4. No doxxing

   Do not share private identifying information about another person without consent.

5. No fedjacketing

   Fedjacketing is the baseless accusation that somebody is a fed without receipts or validated evidence, which is ironically a tactic of feds themselves. The site’s other rules on solidarity and the commitment to members being leftist, not liberal or centrist, already give the qualitative parameters that, if enforced, should filter out feds who are just here to disrupt or dissuade us from our movement.

Security & Privacy

Your privacy and security are central to Leftist Solidarity.

• Passwords are never stored in plain text.

  When you create an account, your password is put through PBKDF2-HMAC-SHA256 with a random salt unique to your account before being saved. The salt means two people with the same password do not get the same stored value, so a precomputed table is no use against it, and every guess has to be made against your account alone.

• No IP addresses are logged or stored.

  We do not record IP addresses anywhere. Cloudflare may see them transiently for security, but they are never saved in our database.

• Login uses secure JSON Web Tokens (JWT).

  After login, the server issues a signed JWT stored in your browser’s localStorage. The token contains only your user ID and expiration time – never your password. Each authenticated request sends this token in the Authorization header, and the server verifies it using a secret key (JWT_SECRET). Tokens expire after 7 days; you’ll need to log in again afterward.

• All traffic is encrypted with HTTPS.

  Your connection between your browser and our server is secured by Cloudflare’s free SSL certificate, preventing eavesdropping on the network.

• No tracking cookies or third-party analytics.

  We do not use Google Analytics, Facebook Pixel, or any similar tracking. The only data stored is what you voluntarily provide (email, username, profile bio, posts, etc.).

• The database (Cloudflare D1) is not publicly accessible.

  Only our Cloudflare Worker can query the database via internal bindings. Row-Level Security (RLS) is not used; instead, the Worker enforces authentication and authorisation before any data is read or written.

• Passwords are never sent in plain text over the network.

  Your password is submitted only inside an HTTPS request body, and the server never echoes it back.

• No third-party logins (Google, Facebook, etc.) are integrated – no external tracking.

We take your security seriously. If you have any concerns, please contact us.

Roadmap / Future Plans

Here are my next priorities to work on in developing the site. Please feel free to contact me and let me know if anything should be added.

1. To have organizations have state entries so users can find different organizations in their state, not just their country.
2. To implement a mutual aid feature.
3. To add more content to the learn tab.
4. To keep expanding the profile avatar presets users can choose from.
5. To eventually allow image uploads.
6. To eventually implement a messaging system on the website.

Please contact me if you have anything you want to add.
