Why it exists

High-risk habits move fast. Decipler puts a pause in the path.

When a habit becomes automatic, even a short pause can make a difference. Decipler adds practical friction without shame, giving you space to notice the trigger and decide what happens next.

Protection center

Protection shaped around your needs.

Choose a category or add a specific website. You stay in control of what Decipler blocks.

Gambling

Betting pages, casino sites, lottery funnels, and promo-heavy content.

Gaming

Game stores, browser games, launchers, and communities that become time sinks.

Liquor

Alcohol delivery, nightlife pages, liquor promotions, and related search paths.

Violence

Graphic media, harmful communities, and unsafe content spirals.

Adult Content

Explicit sites, search funnels, and sensitive content that needs firm guardrails.

Social Feeds

Feeds, reels, shorts, and scroll loops that quietly consume attention.

Intervention flow

From trigger to better next action.

Decipler is designed around the moment a user is about to cross a line. A blocked attempt becomes a chance to name the trigger, write it out, and return with more clarity.

01

Enable guardrails

Select high-risk categories and add exact websites that should stay blocked.

02

Block the attempt

When a risky path appears, Decipler records the category and keeps the moment visible.

03

Redirect to journal

Write what triggered the urge, what choice was made, and how the body feels after.

04

Review progress

Use activity and admin views to see patterns over time without exposing private journal text.

One focused toolkit

The support you need, right when you need it.

Protection, reflection, and progress live in one simple experience, so you can act in the moment and learn from it later.

  • Flexible categories and custom website lists
  • Private journaling for triggers and difficult moments
  • Clear activity trends that help make progress visible

Privacy posture

Accountability without oversharing.

Sync is explained clearly

When you sign in, journal entries, protection settings, and custom website lists sync to your Decipler account.

You choose what to publish

Journal text is not posted to the community unless you separately choose to copy and publish it there.

Know your privacy rights

Download Beta Version

Installation guide

Set up Decipler on your device.

Follow the guide for your platform. Download Decipler only from this website or the linked official Decipler GitHub release.

Android Install the APK

For supported Android phones and tablets.

  1. 1
    Download

    Tap Download Android APK above, then open the completed file from your notification or Downloads folder.

  2. 2
    Allow this source

    If Android asks, open Settings and allow your browser or file manager to install unknown apps. Return to the APK afterward; you can turn this permission off again after installation.

  3. 3
    Install and open

    Tap Install, then Open. Version 1.25 adds confirmation popups and clear success or error notifications for important actions.

  4. 4
    Enable protection

    Sign in, choose your shields, tap Enable Website VPN, and approve Android's VPN prompt.

One-time step when moving from v1.21

If you already installed v1.22, v1.23, or v1.24, install v1.25 directly as an update. If you still use v1.21 or an older build, sync your account data, uninstall the old app once, then install v1.25 because the privacy-safe signing certificate changed in v1.22.
