Poly Text — The Four Stars

Effective Date: March 16, 2026 · Last Updated: May 12, 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.

f) Advertising Identifiers. Our advertising partner (Google AdMob) and its sub-processors may collect your mobile advertising identifier (Google Advertising ID on Android, IDFA on iOS), IP address, approximate (city-level) location derived from your IP, device information (model, OS version, language, time zone), and ad interaction events to serve, measure, and prevent fraud in advertisements. See Section 11 for full 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
  • Serve advertisements within the Service, and measure ad performance and prevent ad fraud
  • 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

Except for advertising identifiers shared with our ad partner (described in Section 11), 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.
  • Google AdMob: Advertising identifiers and limited device and ad-event data are shared with Google AdMob and its ad partners to serve and measure advertisements. See Section 11 for details.
  • 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.

11. Advertising

The Poly Text app displays third-party advertisements provided by Google AdMob, a service of Google LLC. This section explains how ads work and what information is collected when ads are served.

a) Advertising Partner. We use Google AdMob to serve advertisements. Google and its third-party advertising partners (collectively, "ad partners") use cookies, software development kits (SDKs), web beacons, and similar tracking technologies to deliver and measure ads.

b) Information Collected by Ad Partners. Google AdMob and its ad partners may collect or receive:

  • Your mobile advertising identifier (Google Advertising ID on Android, IDFA on iOS), where available
  • IP address and approximate (city-level) location derived from it
  • Device information (manufacturer, model, OS version, language, time zone, screen size, network type)
  • Ad-event data (impressions, clicks, conversions, viewability, time spent)
  • App-level signals (the fact that you are using Poly Text, app version)

c) Personalized vs. Non-Personalized Ads. Depending on your jurisdiction and consent choices, Google AdMob may serve personalized ads (selected based on prior activity across apps and sites) or non-personalized ads (contextual only, based on the current app context and coarse geographic location). Non-personalized ads still use limited data such as IP address and ad-event signals to deliver and measure the ad.

d) Consent for Users in the EEA, UK, and Switzerland (GDPR). If you are located in the European Economic Area, the United Kingdom, or Switzerland, we use Google's User Messaging Platform (UMP), a Google-certified Consent Management Platform, to obtain your consent under the GDPR and the ePrivacy Directive before serving personalized ads or storing advertising identifiers on your device. You may withdraw or update your consent at any time from the in-app privacy settings, which will re-display the UMP consent form.

e) California Residents (CCPA / CPRA). Under the California Consumer Privacy Act (as amended by the CPRA), the disclosure of advertising identifiers and related signals to Google AdMob and its ad partners for cross-context behavioral advertising may be considered a "sale" or "sharing" of personal information. California residents have the right to opt out of such sharing. You may opt out by:

  • Emailing us at [email protected] to request that Google's Restricted Data Processing (RDP) be enabled for your traffic
  • Enabling "Limit Ad Tracking" or denying the App Tracking Transparency prompt on iOS
  • Enabling "Opt out of Ads Personalization" on Android

f) Apple App Tracking Transparency (iOS). On iOS, the app will display Apple's App Tracking Transparency prompt before the IDFA is accessed. If you decline, no IDFA is shared and Google AdMob will serve non-personalized ads only.

g) Children. The Service is not directed to children under 13, and we do not knowingly serve advertisements to users we know to be under 13. Our ad requests are not flagged as child-directed.

h) Learn More and Opt Out. To learn how Google collects and uses information from apps that use its services, see Google's partner privacy policy at policies.google.com/technologies/partner-sites. You can manage your Google ad personalization settings at adssettings.google.com.
