How Deter works
Deter meets the moment between urge and action with protection first, then a calm path forward.
Trying to open an adult or personally blocked site is intercepted before the page can load.
A calm intervention screen brings back your reason, your streak, and a simple trigger check-in.
Start a five-minute Reset to step away from the urge and create space before deciding.
Return to what you actually wanted to do, with brief Rescue Coach support available when you choose it.
Built for the difficult moment
Protection is the foundation. Deter adds a deliberate pause, personal context, and focused tools that help you act on the choice you already made.
Core protection
Built-in and custom domain rules stop blocked navigations before explicit pages render.
Create space
A short, structured pause helps you move away from the immediate urge before you decide what comes next.
See the commitment you have kept, one day at a time—without shame or public comparison.
Adds a five-minute pause before Protection can be turned off, reducing impulsive changes.
Brief, in-the-moment support with clear limits. It is not therapy or an emergency service.
A calmer interruption
Instead of showing explicit content—or a cold error screen—Deter returns you to the intention you set when the moment was easier.
