The only habit tracker with no backdoor
Other apps promise privacy. DopaLoop makes it technically impossible to see your data. No servers. No cloud. No analytics. No excuses. Just your data on your device.
Why users switch to DopaLoop
Real reasons from people who take privacy seriously
"I didn't want to trust a cloud server anymore"
My old habit tracker had privacy promises. Then the ToS changed. Suddenly: 'We share anonymized data with partners.' With DopaLoop there are no servers to collect data. No ToS that can change. No 'partners' to share with. Technically impossible.
"After the last data breach, I wanted absolute security"
2024: 50+ health apps hacked. Millions of habit data leaked online. I asked myself: When is my app next? With DopaLoop I sleep well at night. There's nothing to hack. My data is only on my iPhone. End of story.
"I wanted privacy I could verify"
I'm a developer. I know the tricks: 'Privacy-focused' often just means 'we don't sell directly to advertisers'. DopaLoop's architecture is clear: No backend code. No API. No server. That's verifiable privacy – not just marketing.
The no-server architecture
How DopaLoop guarantees privacy – technically explained
No server code exists
DopaLoop has no backend code. Not 'inactive' – non-existent. There are: • No API endpoints • No database with user data • No server logs • No way for me to receive data This isn't 'I don't collect' – it's 'I can't collect'.
SwiftData: Local, encrypted, yours
All data is stored with Apple's SwiftData on your device. This means: • Encryption by iOS • Access only for you (via Face ID / Touch ID) • No cloud sync • No server that could read along
On-device AI & speech recognition
Voice Journaling uses on-device speech recognition – directly on your iPhone. Your voice: • Stays locally on your device • Never leaves your iPhone • Is not sent to the cloud • Is technically impossible for me to hear
Backup & Export – your control
Your data is saved as part of your iPhone backup (iTunes/Finder or iCloud). You can optionally include voice notes in backups. Additionally: • JSON export anytime • Import on a new device • Full control over your data • No cloud sync needed
Privacy you can see
No cloud, no servers, no tracking. All your habit data stays on your device. Verifiable, not just promised.
Why I don't want servers
I'm Stephan, the developer of DopaLoop. I could have servers. It would be easier for me. Sync would work better. Analytics would show me which features get used. But I don't want to see your data. Not because I'm a good person. But because I know: Data I don't have, I can't lose. Can't sell. Can't misuse. Can't get hacked. The best privacy strategy is: Don't collect data in the first place. That's DopaLoop.
