ZERO-KNOWLEDGE ENCRYPTION · IOS & ANDROID
Hexis is the ancient Greek idea that a habit, practiced deeply enough, stops being something you do and becomes who you are. Hexys is built around that, with science-based tools, an AI companion, and a journal encrypted on your device before it ever reaches our servers. We cannot read it. Nobody can.

WHY IT MATTERS
Compulsive pornography use rewires the brain's reward system. It reduces gray matter in the prefrontal cortex, the part responsible for impulse control, and tolerance builds the same way drug tolerance does. Most apps treat this like a willpower problem. It is not.
Based on peer-reviewed research in behavioral neuroscience and addiction medicine, including Kühn & Gallinat (JAMA Psychiatry, 2014).

Arcos, your AI companion, explains what's happening in your dopamine system rather than telling you why you should feel guilty.

Three separate identities (display name, pod alias, community alias) that are architecturally unlinkable.

iOS uses Apple's Safari Content Blocker to stop adult sites in Safari and any WebKit app. Android uses a system-level VPN-DNS filter.

Seven levels from Hexed to HEXYS, a dual-ring tracking your streak and XP, twelve daily ways to earn progress.
06 ─────────
Six anonymous sections, AI moderation on every post, weekly challenges, and a leaderboard. None using real names.
ZERO-KNOWLEDGE
Your journal is AES-256 encrypted on your device. We store ciphertext only. Even if subpoenaed, even if hacked, there is mathematically nothing for us to read.
Try it: type into the YOUR DEVICE field and watch the ciphertext update live.
INSIDE HEXYS





TWO PATHS · ONE GOAL
Sometimes you don't have someone you can tell. Sometimes the embarrassment makes it impossible. Either way, Hexys gives you two paths, and you can use one or both.
You're matched with four other people working on the same thing. You never use your real name inside a pod. Your pod alias is completely separate from every other identity you have in the app.
Invite a friend, a family member, or anyone you trust. They receive a regular email digest of your progress, including streak days, check-ins, and milestones. They never have to download the app.

Journaling is one of the most evidence-backed tools for quitting porn. Here's how to use it in a way that actually works.
One week ago we launched on the Apple App Store. Today, we're on Google Play too. Here's where we are, what we built, and why it matters.
After a longer road than I'd planned, Hexys received App Store approval this week. We launch on iOS this coming Wednesday, May 6.
