Privacy Policy

Last Updated: January 2026

Introduction

Welcome to Perioo. We are committed to protecting your privacy and handling your data transparently and securely. This Privacy Policy explains how we collect, use, and protect your information when you use our mobile application.

Our core principle: Your data stays on your device. We do not collect, transmit, or store any of your personal information on external servers.

Information Collection

We do not collect any of your personal data. Perioo is a fully offline application.

What You Store Locally

Any information you enter is stored only on your device:

• Health and wellness data you choose to log
• Personal notes and preferences
• App settings

What We Never Access

• We have no servers that receive your health data
• We cannot see, access, or retrieve any personal information you enter
• Biometric data is handled entirely by your device's secure enclave

Analytics Data

We use Firebase Analytics to collect anonymous usage analytics to improve the app:

• App crashes and error reports
• Feature usage statistics (which screens are used, not what you enter)
• Device type and operating system version

This data is anonymous and cannot be linked to your personal information or health data. You can opt out of analytics in Settings.

Data Sharing

We Do NOT Share Your Data

Perioo does not:

• Transmit your personal or health data to external servers

User-Controlled Sharing

Your Rights

You can access, export, correct, or delete your data at any time directly through the app.

Data Retention

• Data remains on your device until you delete it

Children's Privacy

Usage of the App is restricted to users who are 13 years of age or older. Users between 13 and 16 years of age in certain jurisdictions may require parental consent. Because all data is stored locally and we collect no information externally, there are no remote data collection concerns.
