Privacy Policy
Poly Text — The Four Stars
Effective Date: March 16, 2026 · Last Updated: March 16, 2026
The Four Stars ("Company," "we," "us," or "our") operates the Poly Text mobile application and related services (collectively, the "Service"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our Service. Please read this policy carefully. By using the Service, you consent to the practices described herein.
1. Information We Collect
a) Information You Provide. When you create an account, we may collect your name, email address, and authentication credentials (via Google Sign-In or email/password registration). If you use the Service as a guest (anonymous account), we collect only a device-generated identifier.
b) Text Content. When you submit text for processing (rephrasing, fixing, or reply generation), that text is transmitted to our servers for processing by AI models. We retain a history of processed text associated with your account to provide the history feature.
c) Attachments. If you attach images, PDFs, or audio files, these are temporarily transmitted to our servers for processing and are not permanently stored after processing is complete.
d) Usage & Device Data. We automatically collect device type, operating system version, app version, language preferences, and general usage patterns (e.g., features used, session duration) to improve the Service.
e) Purchase Information. If you subscribe to a paid plan, payment transactions are processed by Apple App Store or Google Play Store. We receive a purchase receipt for verification but do not collect or store your payment card details.
2. How We Use Your Information
We use the information we collect to:
- Provide, operate, and maintain the Service
- Process your text submissions and deliver results
- Authenticate your identity and manage your account
- Process and verify subscription purchases
- Maintain your text processing history
- Improve, personalize, and expand the Service
- Communicate with you for support and updates
- Detect and prevent fraud, abuse, or security incidents
- Comply with legal obligations
3. AI Processing & Third-Party AI Providers
Text you submit is processed using third-party AI language models to deliver rephrasing, grammar correction, and reply generation features. Your text content is sent to these AI providers solely for the purpose of generating results. We do not use your submitted text to train AI models. Our AI providers are contractually prohibited from using your data for their own training purposes.
4. Data Sharing & Third-Party Services
We do not sell, rent, or trade your personal information. We may share your data only in the following circumstances:
- Service Providers: Firebase (authentication, hosting), AI processing providers, and cloud infrastructure providers who assist in operating the Service, bound by confidentiality obligations.
- Legal Requirements: When required by law, court order, or governmental authority.
- Business Transfers: In connection with a merger, acquisition, or sale of assets, your data may be transferred to the acquiring entity.
5. Data Retention
We retain your account information and text processing history for as long as your account is active or as needed to provide the Service. Attachment data (images, PDFs, audio) is processed in real time and not retained after processing. You may delete your account at any time, which will result in the permanent deletion of your personal data and text history from our systems within 30 days.
6. Data Security
We implement industry-standard security measures, including encryption in transit (TLS/SSL), secure authentication via Firebase Auth, and access controls on our servers. However, no method of electronic transmission or storage is 100% secure, and we cannot guarantee absolute security.
7. Your Rights & Choices
Depending on your jurisdiction, you may have the right to:
- Access the personal data we hold about you
- Request correction of inaccurate data
- Request deletion of your data and account
- Withdraw consent for data processing
- Export your data in a portable format
- Object to or restrict certain processing activities
To exercise any of these rights, use the "Delete Account" feature within the app or contact us at [email protected].
8. Children's Privacy
The Service is not intended for children under 13 years of age. We do not knowingly collect personal information from children under 13. If we become aware that we have collected data from a child under 13, we will take steps to delete it promptly.
9. International Data Transfers
Your information may be transferred to and processed in countries other than your country of residence. These countries may have different data protection laws. By using the Service, you consent to such transfers. We take appropriate safeguards to ensure your data remains protected in accordance with this Privacy Policy.
10. Changes to This Policy
We may update this Privacy Policy from time to time. We will notify you of material changes by posting the updated policy within the app or by email. The "Last Updated" date at the top indicates when the latest revisions were made. Your continued use of the Service after any changes constitutes acceptance of the updated policy.
