This Privacy Policy explains how personal data is collected, used, and protected when using the mobile application Vina (“the App”).

Vina is designed to help remind users to take or use a contraceptive method and to display cycle-related information.

2. Data we process

2.1. User-entered data

This data is stored on your device and, if you connect your Google account, also in the cloud (Firebase Cloud Firestore):

• Selected contraceptive method.
• Cycle configuration (start date, active days, break days).
• Reminder schedule.
• Adherence log (whether you took the method, streaks, percentages).
• Personal notes, mood entries, and recorded symptoms.
• Recorded menstrual periods.
• Language, theme, and notification preferences.

2.2. Google account data (optional)

If you choose to link your Google account for cloud backup, we store:

• Email address associated with your Google account.
• Display name from your Google account.
• Unique user identifier (Firebase Authentication UID).

This data is used solely to identify your backup and enable cross-device synchronization.

All this data is used exclusively to provide the App’s functionality. It is not sold or shared with third parties.

2.3. Technical and usage data (Firebase)

The App may use Google/Firebase services:

• Firebase Analytics (usage statistics).
• Firebase Crashlytics (crash reports).
• Google AdMob (ads, if enabled).

These services may automatically collect:

• Device model, OS version, App version.
• Language and approximate region.
• Advertising identifiers.
• Basic usage events.
• Crash logs.

This technical data is not linked to your cycle data.

3. Purposes of processing

1. Provide and maintain the App: save settings, show cycles, etc.
2. Local reminders: schedule notifications on your device.
3. Improve the App: aggregated analytics and crash reports.
4. Advertising (optional): display ads (personalized or non-personalized depending on regulations).

4. Legal basis

- Performance of a contract: essential App functionality.
- Consent: analytics/ads depending on jurisdiction.
- Legitimate interest: security, diagnostics, and product improvement.

5. Data retention

- Local data remains on your device as long as the App is installed.
- If you connect your Google account, data is stored in Firebase Cloud Firestore until you explicitly delete it.
- Technical Firebase data (Analytics, Crashlytics) is retained according to the provider’s policies.

6. Data sharing

No personal data is sold.

Data may be processed by:

• Google LLC (Firebase, Google Cloud, AdMob), which may process data outside the EEA.

7. International data transfers

Transfers through Firebase may occur, covered by EU Standard Contractual Clauses or equivalent safeguards.

8. User rights

You may request:

• Access to your data
• Rectification
• Deletion
• Restriction of processing
• Objection
• Portability

8.1. How to delete your data

You can delete all your data (from the device and the cloud) directly from the App:

1. Open the App and go to the Settings tab.
2. In the Backup section, tap the "Delete my data" button.
3. Confirm the deletion in the dialog that appears.

This action will permanently delete:

• All your notes, mood entries, and symptoms.
• All your period records.
• Your adherence history.
• Your settings and configuration.
• All data stored in the cloud (if you had a Google account linked).

This action is irreversible. After deletion, you will be signed out automatically.

You can also delete your local data by uninstalling the App from your device.

To request deletion via email or exercise any other right, contact:

9. Children

The App is intended for adult users. If you are under 14, you must use the App with parental consent.

10. Security

We apply reasonable technical and organizational measures to protect data.

11. Changes to this Policy

Any major update will be announced through the App or this page.
