Why proof exists at all
Every habit tracker has the same quiet failure mode: the checkbox. At some point, tired and craving the feed, you tap "done" on a workout that didn't happen. Nobody sees it. The streak survives. The habit dies.
Broc is a habit-based app blocker: block distracting apps, do a real habit, prove it with a photo, earn the unlock. Verification is the "prove it" part, and it's what makes the unlock mean something. No other app blocker checks whether the habit actually happened.
How it works
You finish a habit with verification on. Instead of a checkbox, the camera opens.
You photograph the evidence. The gym floor, the open book, your running shoes on the trail, the cleared desk.
The AI checks the match. The photo goes securely to Broc's server, then to the AI provider (OpenAI), which answers one question: does this photo plausibly show this habit?
Pass or fail comes back. That's all that's kept. Pass marks the habit done and earns your unlock. The photo is not saved on Broc's servers after the check.
The privacy part, straight
| Question | Answer |
|---|---|
| Is the photo stored? | Not after the check. Broc keeps the pass/fail result, not the image. |
| Who sees it? | No human review. The photo is processed by the AI provider (OpenAI) via API. |
| Is it used to train AI? | No. OpenAI does not use API images for training. |
| Can I opt out? | It's opt-in, per habit. Leave it off and no photos are ever taken. |
| What else can Broc see on my phone? | Only which app is currently open (Android Usage Access), checked on-device against your block list. No usage history is stored or sent, no keylogging, no screen recording. |
The full details live in the privacy policy. If anything there doesn't match what you see in the app, email developer@getbroc.app and it gets fixed.
"Can't you cheat it?"
The most asked question, so here's the honest answer: people try, and the model is better at this than you'd hope. A photo of your ceiling doesn't pass "went to the gym". Yesterday's photo is a gamble because the check looks at whether the scene plausibly matches the habit now.
And if you defeat it anyway? You've spent real ingenuity to avoid ten pushups, and the streak you're protecting is now fiction. The app can't want the habit more than you do. It just makes wanting it enough.
Common questions
Is verification included?
Yes. Every Broc subscription includes it (7-day free trial), along with unlimited habits, custom unlock durations and full history.
Does verification work offline?
No, the check needs a connection. Without one, verify when you're back online.
Which habits suit photo proof?
Anything that leaves visible evidence: gym sessions, reading, a tidied room, meal prep, being at the library. For habits with nothing to photograph (meditation, say), leave verification off for that habit.
