Frequently asked questions
Everything you need to know about Streak.
What is calorie cycling?
+
Calorie cycling is a nutrition strategy where you consume different calorie amounts on different days — typically more calories on training days and fewer on rest days. This matches energy intake to energy expenditure and may help preserve metabolic rate during fat loss while supporting recovery on training days.
How does Streak calculate my calorie targets?
+
Streak uses the Mifflin-St Jeor equation to calculate your Basal Metabolic Rate (BMR), then applies an activity multiplier to estimate your Total Daily Energy Expenditure (TDEE). Calorie targets for training and rest days are derived from your TDEE based on your goal — fat loss, body recomposition, or lean bulk — with periodized phases that adjust over time.
Does Streak work without an Apple Watch?
+
Yes. Streak runs on iPhone alone. Apple Health (HealthKit) integration is optional and used only for syncing weight data when you grant permission — no Apple Watch required.
Is my health data shared with advertisers?
+
No. Streak never sells, licenses, or shares health and fitness data with advertisers, data brokers, or any third party for advertising purposes. HealthKit data is processed locally where possible, encrypted in transit (TLS 1.3) and at rest (AES-256), and stored on EU-based servers (Frankfurt, Germany).
What is body recomposition?
+
Body recomposition is the process of simultaneously losing fat and gaining muscle. It typically requires eating at or near maintenance calories with adequate protein (1.6–2.2 g/kg bodyweight) combined with progressive resistance training.
How much does Streak cost?
+
Streak offers a 3-day free trial with full access to all features. After the trial, Pro is €9.99 per month or €34.99 per year (about 71% off the monthly rate). No credit card required to start.
Can I cancel anytime?
+
Yes. Subscriptions are managed through your Apple ID and can be canceled anytime in iOS Settings > [Your Name] > Subscriptions. You keep Pro access until the end of the current billing period.
