FMRL Ink

fmrl.ink provides ephemeral, anonymous, and secure mailing lists, ideal for short-term collaborations, activist organizing, and temporary group communication. Subscribers remain completely anonymous, and all subscription data is permanently erased upon expiry, ensuring maximum privacy.

⚙️ How It Works

Create a Mailing List:
Send an email with the subject line 3 days (or any number of days) to:
```
anykeyword@fmrl.ink
```
This subscribes your email anonymously for the specified number of days.
Notify Others:
CC additional recipients to notify them of the group’s existence. They can subscribe similarly.
Anonymity Guaranteed:
Any email sent to the generated address will anonymously forward to all current subscribers.
Automatic Expiration:
After the subscription duration ends, you’re automatically unsubscribed. When no subscribers remain, the list permanently disappears, leaving no trace.

📬 Commands & Shortcuts

Subscribe: Send an email with subject X days.
Unsubscribe: Subject line: unsubscribe or click the unsubscribe link at the bottom of emails.
Extend Subscription: Subject line: extend X.
Help: Subject line: help to receive detailed instructions.

🔐 Privacy & Security Guarantees

Ephemeral Storage: All subscriber data is deleted permanently once expired.
Anonymous Emails: Sender identity and subscriber lists are never revealed.
Encryption: Subscribers’ emails are encrypted with Google Cloud KMS.
Court-proof Privacy: Algorithmic privacy ensures no historical subscriber data can ever be recovered or accessed.
