“I used to dread opening texts from my ex. Now I just read the facts and move on with my day.”

Why not just block them?
Blocking cuts you off. Doing nothing wears you down. Quell is the middle ground.
| Do nothing | Block them | Quell | |
|---|---|---|---|
| Hostile messages | You read every word | You miss important info | Rewritten calm, facts intact |
| Emergencies | Mixed in with the noise | Blocked entirely | Always delivered immediately |
| Your replies | Risk escalating | Can’t reply at all | Go through unmodified |
| Evidence / admissions | Lost in the chaos | Never received | Forwarded verbatim |
| Your peace of mind | Constantly on edge | Guilt and missed info | Calm and in control |
Privacy you don’t have to take our word for.
