Privacy Policy for Safekeep
DevDuo's ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we handle your information when you use our Safekeep mobile application (the "Service").
1. The "Zero-Knowledge" Principle
Safekeep is a **zero-knowledge** application. This means we, the developers, have zero access to the files you encrypt or the Master Key you create. Your data's privacy is mathematically guaranteed by the encryption itself, which occurs exclusively on your device.
2. Information We Do Not Collect
- **Your Master Key:** Your Master Key is created by you and is never transmitted to our servers. We cannot recover it if you lose it.
- **Your Files:** The contents of the files you choose to encrypt are never uploaded or visible to us.
- **Personal Information:** We do not require you to create an account with personal details like your name or address to use the core features of the app.
3. Information We Collect
Our collection is limited to what is essential for the app's functionality and improvement:
- Google Account Information (Optional): If you choose to sign in with Google to enable cloud backup, we receive your email address and basic profile information from Google for authentication purposes only. This allows us to connect the Service to your personal Google Drive account.
- Anonymous Analytics: We may collect anonymous, aggregated usage data, such as app crashes, session duration, and feature usage. This data is not personally identifiable and helps us improve the app's stability and user experience.
- Purchase Information (Premium Users): If you subscribe to Safekeep Premium, the transaction is handled by the respective app store (Google Play). We receive anonymous purchase tokens to verify your subscription status but do not receive your payment information.
4. How Your Data Is Used
- Cloud Backup (Optional): If you sign in, the Service will create a private folder named "safekeep-data" in your own Google Drive. Your encrypted files are stored there. We do not have permission to access any other part of your Google Drive.
- Service Improvement: Anonymous analytics help us identify bugs, understand which features are popular, and make the app better.
5. Data Security
We implement industry-standard security measures, but the ultimate security of your files rests on the strength of your Master Key and the principle of on-device, end-to-end encryption.
6. Changes to This Privacy Policy
We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page. You are advised to review this Privacy Policy periodically for any changes.
