FAQ
How does Vela protect my privacy?
Vela is designed with zero-knowledge architecture, meaning your cycle data stays on your device and is protected by iOS Data Protection. If you opt for cloud backup, your data is end-to-end encrypted before it leaves your device, ensuring even Vela's servers cannot access it.
How accurate are Vela's predictions?
Vela's prediction engine uses clinically-informed algorithms that combine established menstrual cycle prediction methods with weighted moving averages. Predictions for your period, ovulation window, and fertile days become more accurate the longer you track, as the app learns your unique patterns.
What is 'The Garden' feature in Vela?
The Garden is a unique gamification feature where a botanical garden grows as you consistently track your cycle. Plants bloom with your consistency and wilt if you miss tracking days, offering a visual, guilt-free reflection of your self-care journey with Studio Ghibli-inspired art.
Is Vela inclusive for all users?
Yes, Vela is designed for every body that cycles, using hormone-aware terminology and avoiding gendered assumptions. It supports HRT tracking for trans and non-binary users and offers a partner mode for dual-cycle tracking.
How does Vela's pill reminder work?
Vela's pill reminder is a persistent notification that stays on your lock screen until you tap 'Taken' or 'Skip'. This design aims for real accountability with oral contraceptives.
What are the subscription options for Vela Premium?
Vela Premium offers two subscription plans: a monthly option for $7.99/month and an annual option for $39.99/year. Both plans include a 7-day free trial.
Does Vela have ads?
