Your habits reveal who you are
When you sleep. Whether you exercise. How often you meditate. If you take your medication. These aren't just data points – this is you. This information belongs to nobody but you. Not the cloud. Not a company. Not advertisers. Only you.
What could go wrong?
With other apps. Not with DopaLoop.
Your habit data gets sold
You track: 'Drink less', 'Sleep more', 'Take medication'. A habit app with servers sees this. Their business model changes. Suddenly anonymized data gets sold. Your health habits end up with insurers, advertisers, data brokers. Technically impossible with DopaLoop. There are no servers. I can't see your data – so I can't sell it.
Servers get hacked
2024: Over 1.7 billion personal records compromised (ITRC, 2025). Health data, habits, private journals – all public. The company says: 'We regret...' But your data is out there. Forever. With DopaLoop there's nothing to hack. No servers, no cloud, no central target.
"Anonymized" data isn't anonymous
A study showed: 87% of US citizens can be identified with just 3 data points (Sweeney, 2000). Your sleep patterns + workout times + meditation frequency? That's probably only you. Apps promise: 'Anonymized and safe'. Reality: Re-identification is trivial. With DopaLoop there's no anonymization. Because there's no data collection.
How DopaLoop guarantees privacy
Not marketing. Architecture.
No servers, no database, no backend
DopaLoop has no server infrastructure. No database with user data. No backend collecting information. What does this mean? It's technically impossible for me to see your data. Even if I wanted to (I don't), I couldn't.
No account, no email, no identification
You install the app. You open it. You start. No login. No email verification. No user ID that could track you. You stay anonymous – even from me.
Zero analytics. Really.
No Firebase. No Mixpanel. No Google Analytics. No analytics or tracking SDKs. I don't know: • How often you open the app • Which features you use • Where you live • Who you are And that's exactly how I want it.
Export & Import – your control
Back up your data as a JSON file and transfer it to another device. You decide when and where. No cloud needed.
Why I take privacy seriously
I'm Stephan, the developer of DopaLoop. I have ADHD. I track sensitive habits: medication, sleep, mood. I know how intimate this data is. I wanted an app I could use myself – without fear my data ends up somewhere. So I built DopaLoop without servers. Privacy-first isn't a marketing strategy. It's personal. Your habits belong to you. Not me. Not the cloud. You.
