Privacy Policy

Shevalion was built with a simple privacy principle: your data lives on your device.

What we store locally on your phone

The following stays in your browser's local storage, not on our servers. When you use the AI coach, a summary of it is sent with your message (see below):

• Your profile (name, age, life stage, goals, training experience)
• Cycle log (period dates, symptoms, mood, BBT, energy)
• Bloodwork values you log or scan
• Nutrition entries (meals, macros, daily totals)
• Weekly check-in summaries
• Subscription status and preferences
• Notification settings

Clearing your browser data, uninstalling the PWA, or using "Clear all my data" in Settings will permanently delete this information.

If you ask us to email your plan

If you enter your email address to receive your plan, we store that address together with the app you use, your goal, your program name, your sex if you entered it yourself, whether you agreed to receive tips and offers, and the date. We use it to send you your plan and — only if you ticked the box — occasional tips and offers, each with an unsubscribe link. The email is sent through our email provider (Resend). We keep it until you unsubscribe or ask us to delete it. Ask us at rockpros@gmail.com and we will delete it.

What gets sent to AI providers

When you chat with Shevalion, your messages and context (profile, current cycle phase, recent bloodwork, nutrition logs) travel to Anthropic or OpenAI to generate a response. Under their commercial API terms, conversations are not used to train models.

Cycle data privacy

Your menstrual cycle data is treated with the same on-device-only principle as everything else. We never send it to any server we control. It is only included in the AI conversation context for the duration of that conversation.

Bloodwork scanning

The "Scan" feature sends the image to our AI vision provider to extract values. The image is not stored by us.

Cookies and tracking

No third-party tracking. No analytics. No advertising networks. No data brokerage.

Links to other companies

Some links in the app to other companies — for example the recommended gear and supplements on Amazon and meal delivery companies — may be affiliate links or come with a promo code, and we may earn a commission if you buy through them. Opening one is an ordinary visit to that company's site: no personal or health data from the app is sent with it.

Account data (when you subscribe)

Stripe processes subscriptions. We retain only subscription status and a billing email. No card data is stored by us.

Children

Shevalion is for adults age 18 and older.
