Privacy Policy

Information we collect

Account information: your name, email address, language preference and, if you sign in with Google, the basic profile information Google shares with us (name, email and profile picture).

Health and wellbeing information you choose to log: period dates, cycle and period length, symptoms and their intensity, mood, energy, notes, completed workouts and optional date of birth.

Daily log details you choose to record in the app: menstrual flow, sexual activity and protection, cervical mucus, ovulation and pregnancy test results, breast self-exam findings, weight, basal body temperature and water intake, together with your goal (tracking periods, trying to conceive or pregnancy), pregnancy dates, prediction settings, units and display preferences, custom symptoms, self-care progress and the articles you have read. They are saved on your device and synced to your account so you can restore them on a new phone.

Kept only on your device: reminder settings, including the names of medications you add, and your app lock PIN, which is stored encrypted by the operating system. Fingerprint or face unlock is handled by your phone, and LunaFit never receives biometric data.

Community content: posts, comments and likes you publish in the LunaFit community, shown to other signed-in members with your first name and profile picture.

Luna AI conversations: the messages you send to Luna AI and the cycle estimate needed to answer them. LunaFit does not store the content of these conversations.

How we use your information

To provide the service: calculating your cycle day, phase, fertile window and next period, showing your history, charts and personalized recommendations.

To send the emails you expect: account confirmation, the welcome email and, if enabled, period and ovulation reminders.

To keep LunaFit safe: preventing abuse, moderating reported community content and protecting accounts.

We do not sell your personal information and we never use your health data for advertising.

Service providers

We rely on trusted providers that process data on our behalf: Supabase (database and authentication), Vercel (hosting), Cloudflare (video storage), Resend (email delivery), Google (optional sign-in, Google Play billing and AdMob advertising) and DeepSeek (the AI model that powers Luna AI). They may only use your data to provide their services to LunaFit.

When you use Luna AI, your messages and the cycle estimate needed to answer them are sent to DeepSeek and processed on its servers in the People's Republic of China. We send only what is needed to answer you, never your email address. If you do not want this data to leave your country, do not use Luna AI; every other feature works without it.

Advertising and purchases

The free version of the LunaFit app shows a limited number of ads served by Google AdMob, and some tools can be unlocked for 24 hours by watching a short video. AdMob may collect your device's advertising ID, IP address and general ad interaction data to show and measure ads. It never receives your health logs, cycle data, symptoms or Luna AI conversations.

Where the law requires it, we ask for your consent before ads are personalized, and you can change that choice at any time from Profile › Privacy & security. You can also reset or delete your advertising ID in your phone's settings. LunaFit Premium removes all ads.

Subscriptions in the app are processed by Google Play. We receive a purchase token to confirm your plan, never your card or payment details.

Retention and deletion

We keep your information while your account is active. You can download a copy of your data or permanently delete your account at any time from Profile › Privacy & security. Deleting your account removes your profile, logs and community content.

Your rights and choices

You can access, correct, export or delete your information in the app, turn email reminders on or off, and change your language. For any other request, contact us and we will respond within a reasonable time.

Security

Data is encrypted in transit, and access rules in our database ensure each person can only read and change their own records. No system is perfectly secure, so please keep your password private.

Children

LunaFit is intended for adults aged 18 and older. We do not knowingly collect information from anyone under 18.

Changes to this policy

We may update this policy. If the changes are significant, we will let you know in the app or by email before they take effect.
