Introduction

At Sumi, we believe privacy is a fundamental right. This Privacy Policy explains how we collect, use, and protect your information when you use our messaging application. We are committed to maintaining the highest standards of privacy and security.

Information We Collect

Account Information

To create your Sumi account, we collect:

• Phone number (for account verification)
• Username (optional)
• Profile picture (optional)

Messages and Media

All your messages, photos, videos, and files are encrypted end-to-end. We cannot read, access, or store the content of your communications. Messages are stored locally on your device.

Technical Information

We collect minimal technical information necessary for the app to function, including device type, operating system version, and app version for troubleshooting purposes.

How We Use Your Information

We use your information solely to:

• Provide and maintain the Sumi messaging service
• Verify your account and prevent fraud
• Improve app performance and fix technical issues
• Send important service updates (rarely)

End-to-End Encryption

All messages sent through Sumi are protected by end-to-end encryption. This means that only you and the recipient can read your messages. Not even Sumi can access the content of your communications. Your messages are encrypted on your device before being sent and can only be decrypted by the recipient's device.

Data Storage and Retention

Your messages are stored locally on your device, not on our servers. We only store:

• Your phone number and username for account management
• Encrypted message metadata (timestamps, delivery status) for up to 30 days
• Technical logs for debugging purposes for up to 7 days

You can delete your account at any time, which will permanently remove all associated data from our servers.

Third-Party Services

Sumi does not integrate with third-party analytics, advertising, or tracking services. We do not share your data with any third parties except as required by law or to protect our users' safety.

Your Rights

You have the right to:

• Access your personal data
• Correct inaccurate information
• Delete your account and associated data
• Export your data (messages are stored locally on your device)
• Opt out of non-essential communications

Security Measures

We implement industry-standard security measures to protect your information, including encryption in transit and at rest, secure authentication protocols, and regular security audits. However, no method of transmission over the internet is 100% secure.

Children's Privacy

Sumi is not intended for children under 13 years of age. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us.

Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any material changes by posting the new Privacy Policy in the app and updating the "Last updated" date. Your continued use of Sumi after any changes constitutes acceptance of the updated policy.
