FAQs
Frequently Asked Questions
Common questions about Suvi and how it works to help you achieve your goals.
Is Suvi really private?
Yes, 100%. Suvi runs entirely on your device. There are no analytics, no crash reporting, no cloud uploads, and no network calls for AI processing. We physically cannot see your data because it never leaves your iPhone.
What iOS version do I need?
Suvi requires iOS 17.0 or later. It works on all iPhones that support iOS 17. The app is also designed to be forward-compatible with iOS 18+ features when they become available.
How does the AI work without internet?
Suvi uses on-device language processing to understand your goals and log entries. When you describe a goal in natural language, it's processed locally using built-in iOS capabilities and our rule-based parsing system. No data is sent anywhere.
What health data does Suvi access?
Suvi can read (not write) sleep data, heart rate, HRV (heart rate variability), step counts, and workout information from Apple Health. All access is optional, and you can use Suvi without connecting to HealthKit.
Can I export or delete my data?
Absolutely. Suvi includes full data export and delete controls. You can export all your data anytime, and delete it whenever you want. Since nothing is stored in the cloud, deletion is immediate and complete.
Is Suvi free?
Yes, Suvi is free to download and use. We believe everyone should have access to tools that help them understand themselves and achieve their goals, without compromising privacy.
