Features FAQ
What data does Sarenica actually collect on my desktop?
Sarenica collects desktop activity signals such as keyboard and mouse patterns, session tracking, and optional wearable sync data. The exact data types are visible in the app and controlled through consent settings.
Do I need a wearable device to use Sarenica?
No. Wearable sync is optional. You can use Sarenica with desktop activity signals only, and add wearable data later if you want richer comparisons and correlation analysis.
Is cloud sync required for Sarenica features?
No. Sarenica is designed to be privacy-first and local-first. Cloud sync is optional and you can control it through settings.
How much data do I need before AI pattern insights become useful?
Basic insights can start early, but pattern and relationship analysis becomes more reliable with at least 7–14 days of tracking and consistent active minutes.
