<p align="center"> <img width="150" src="app/static/img/logo.png"> </img></p> 
<p align="center"> Twitter and Youtube via RSS with privacy </p>
<br>

### In this new version, Parasitter no longer depends on Invidious. [Click on this link](https://github.com/pluja/Parasitter/tree/master) if you want to go to the old version using Invidious (not updated anymore).

Parasitter allows you to follow your favorite Twitter and YouTube accounts with full privacy using rss feeds in order to gather the latest content from your favourite accounts and builds a *beautiful* feed so you can read them. Parasitter is written in Python and Flask and uses Semantic-UI as its CSS framework.

Parasitter is possible thanks to several open-source projects that are listed on the [Powered by](#powered-by) section. Make sure to check out those awesome projects!

## Security
Only the hash of your password is stored on the database. Also no personal information of any kind is kept on the app itself, if a hacker gets access to it only thing they could do would be to follow/unfollow some accounts.

I always recommend self-hosting, as you will be the only person with access to the data.

## Privacy
Parasitter cares about your privacy, and for this it will never make any connection to Twitter or Youtube on the client. We make use of rss feeds to fetch all the tweets from your followed accounts. If you want to use a specific Nitter instance you can replace it on the file `app/routes.py`.

The only things the database stores are:
* Hash of the password
* Username
* List of followed users
* List of saved posts

This data will never be used for any other purpose than offering the service to the user.

The Parasitter server connects to Google (Youtube) in order to gather all the necessary data. Then it serves it (proxied through itself) to the client. This means that as a client, you will never connect to Google - the Parasitter server will do it for you. So if you want to set up a Parasitter server I recommend you to set it up on a remote VPS so you don't share your IP with Google or use a VPN on the server.

> Important note: The **client** never connects to Google / Youtube however, the server does in order to gather all the necessary things!

# Self hosting

### Test
You can test this new version.

##### IMPORTANT: Connections to googlevideo will be made to stream the videos. It is recommended to use a VPS server or a VPN to preserve your privacy. This version is intended for a remote server.

1. Install `python3`, `pip3`, `python3-venv` (optional) and `git`.
2. Clone this repository:
    - `git clone https://github.com/pluja/Parasitter.git`
3. Navigate to the project folder:
    - `cd Parasitter`
4. Change to this branch:
   - `git checkout dev-indep`
5. [Optional] Prepare a virtual environment and activate it (Recommended):

   > Python lets you create virtual environments. This allows you to avoid installing all the `pip` packages on your system.   
   If you don't mind about that, you can jump to step **5.** and ignore everything about "[env]".
    - `python3 -m venv venv`
    - `source venv/bin/activate`
    > Now you are inside of the virtual environment for python. All instructions wiht [env] indicate that must be done inside the env if you decided to create one. From now on, you will always need to start the application from within the virtual env.
6. [env] Update pip
    - `python3 pip install --upgrade pip`
7. [env] Install the required libraries:
    - `python3 pip install -r requirements.txt`
       > Use `sudo` or, preferably `--user`, if not working.
8. [env] Initialize and prepare the database.
    - `flask db init`
    - `flask db migrate`
    - `flask db upgrade`
    > If you get *`"No such command db"`*, try running `source venv/bin/activate` again.
9. [env] Run the application.
    - `flask run`
10. Go to "http://localhost:5000/" and enjoy.

### Updating to new versions:
**IMPORTANT: Before updating to new versions, it is recommended to always export your data on `Settings>ExportData`. A major version update could have changes on the whole database and you may be forced to remove and reset the database!**
1. Navigate to the git repository (the one you cloned when installing).
2. Pull new changes:
    - `git pull`
4. Install new packages (if any):
   - `pip install -r requirements.txt`
   > It may be that there are no new packages to install. In that case, all requirements will be satisfied.

5. Update the database:
    - `flask db migrate`
    - `flask db upgrade`
> If you experience any error in this step, it might be that there were changes on the database. You can solve it by exporting your data, deleting and resetting the database. Run `rm -rf app.db migrations` and then `flask db init`. Then run step 5 normally.

6. Done! You are on latest version.
> **See [CHANGELOG](CHANGELOG.md) for a list of changes.**

### Donate 💌
Testing with a public instance will soon be needed, and I will need to set up a server for this. If I want that Parasitter to go public and host some users I will need a (relativelly) good server and this is somehow expensive for me. So any contribution will be really welcome!

This project is completelly Open Source and is built on my own free time as a hobby. So if you like it, you can buy me a coffee!
