Privacy Policy

cutGPT · a brand of ZStack Capital LLC

Last updated: October 1, 2026

This Privacy Policy describes how ZStack Capital LLC (“cutGPT,” “we,” “us,” or “our”) collects, uses, discloses, and safeguards information when you use the cutGPT mobile apps for iPhone and Android, website (including cutgpt.app), and related services (collectively, the “Service”). By using the Service, you agree to this Privacy Policy. If you do not agree, do not use the Service.

1. What cutGPT is

cutGPT is a free AI chat app and website. If you are not on a paid subscription (if offered), we may show third-party ads—including Google AdSense on the web, Google AdMob in the iPhone and Android apps, and Gravity in the iPhone app—to help fund the product. Eligible users may receive discretionary promotional rewards based on their activity, paid via PayPal after a minimum balance, subject to our Platform Terms. We do not pay you to tap or click ads, and tapping or clicking ads does not increase your rewards.

2. Information we collect

Depending on how you use the Service, we may collect:

  • Account data: identifiers from Sign in with Apple or Google (such as a provider ID and email, if provided), and your Firebase user ID on our systems. If you use the app as a guest, we assign an anonymous Firebase user ID instead.
  • Chat content: messages, conversation history, and images you attach so we can operate the AI product and (where applicable) improve contextual features.
  • Payout data: if you opt in to payouts, a PayPal email and related earnings ledger fields (pending, payable, paid amounts, share rate).
  • Device and app data: device type, OS, app version, a device identifier (IDFV on iPhone, Android ID on Android), App Check / integrity tokens (including Google Play Integrity on Android), crash and performance diagnostics, and analytics events.
  • Ad and attribution data: ad impression events, estimated paid-event values from ad SDKs, SKAdNetwork signals on iPhone, install-referral and attribution data, and consent / privacy preference status for ads. Our ad, analytics, and attribution SDKs may read your device’s advertising identifier: on iPhone, Apple’s IDFA only if you allow tracking when the app asks (you can change this in Settings → Privacy & Security → Tracking); on Android, Google’s advertising ID, which you can reset or delete in your Android settings.
  • Usage data: screens viewed, feature usage, referrals / invite codes, and similar product-interaction data.
  • Support communications: messages you send to [email protected].

3. How we use information

  • Provide, operate, secure, and improve the Service and AI chat features
  • Send chat content to third-party AI providers so they can generate replies (see Section 4)
  • Authenticate you and protect against abuse, fraud, and unauthorized access (including App Check)
  • Show ads that help fund the Service and measure ad performance
  • Measure in-app and ad activity on our servers to administer discretionary rewards / PayPal payouts and prevent fraud
  • Personalize or contextualize ads where permitted by law and your choices
  • Analyze usage, fix bugs, and develop new features
  • Communicate with you about the Service, security, and support
  • Comply with law and enforce our Platform Terms

4. Third-party AI providers

When you use AI chat, we transmit the content you provide—such as messages, recent conversation context, and images you attach—through our servers to third-party AI model providers so they can generate a response. Primary inference is provided by Groq. Depending on routing and features enabled, requests may also be processed by OpenRouter, OpenAI, and/or Anthropic. We require these providers to use the data to deliver the Service and to provide protections that are the same or substantially equivalent to those described in this Policy for the processing they perform on our behalf. In the iPhone and Android apps, we ask for your permission on a Data & Privacy screen before sharing this content with third-party AI for the first time. You can review our current subprocessors list for more detail.

5. Advertising, cookies, consent, and attribution

Website advertising and cookies. Google and other advertising vendors may place or read cookies on your browser, or use web beacons, device identifiers, IP addresses, and similar technologies, to deliver and measure ads. Google may use advertising cookies to serve ads based on visits to cutgpt.app and other websites. You can review or opt out of personalized Google advertising in Google Ads Settings. You can learn how Google uses information from sites and apps that use its services in Google’s partner-sites notice.

EEA / UK / Switzerland choices. Where required, an approved consent message lets you accept or reject personalized advertising before it is used. Rejecting personalized ads does not necessarily remove ads; ads may still appear in a limited or non-personalized form. In the iPhone and Android apps, you may be able to revisit this choice through Settings → Manage Ad Privacy where available. Website consent controls, when shown, provide their own privacy-options link.

Ad measurement. After an ad is shown, Google’s SDK may report an estimated value for that impression on the device. We send that event to our servers with your signed-in account to measure activity, prevent fraud, and administer the rewards program. We do not put your account id, email, or chat text into the AdMob ad request as targeting keywords.

Gravity measurement. When Gravity is the active ad network in the iPhone app, we may pass your account id to Gravity’s publisher API (not as Google ad-request keywords) so activity can be measured per user. Gravity may receive recent chat turns for contextual matching.

Boost. If you choose to watch an optional ad for stronger replies, those replies are generated through OpenRouter (see Section 4). We keep a daily count of boosted replies on your account to monitor usage and prevent abuse. Boost ads are not sent to our servers for the rewards program.

We do not sell your personal information to advertisers. We do not claim that Google, PayPal, or any ad network pays you directly. Any user “cut” is a discretionary program operated by cutGPT as described in the Platform Terms.

6. How we share information

We may share information with:

  • Third-party AI providers such as Groq, and when routing is enabled OpenRouter, OpenAI, and/or Anthropic, to generate AI replies from your chat content (see Section 4).
  • Service providers / subprocessors who help us run the Service (for example hosting, authentication, analytics, crash reporting, ads, payments facilitation, email). See our subprocessors list.
  • Ad partners such as Google AdMob, Gravity (iPhone app only), and related measurement and install-attribution partners, as needed to show and measure ads.
  • Payment facilitators such as PayPal, when you request or receive a payout.
  • Legal and safety disclosures when required by law or to protect rights, safety, and property.
  • Business transfers in connection with a merger, financing, acquisition, or sale of assets.

7. Retention and security

We retain information for as long as needed to operate the Service, administer rewards and disputes, comply with legal obligations, and resolve claims. When you delete your account, we follow the timeline in Section 8. We use administrative, technical, and organizational measures designed to protect information, but no method of transmission or storage is completely secure.

8. Your choices and rights

Depending on your location, you may have rights to access, correct, delete, or restrict certain personal information, or to object to certain processing. To exercise these rights, email [email protected]. We may need to verify your identity.

Deleting your account. You can delete your account in the iPhone or Android app (Settings → Delete Account), on our account deletion page, or by emailing [email protected]. Deleting removes your sign-in account right away on every platform. Within 30 days we delete the chat history, attachments, memory, usage stats, referral code, onboarding answers, and PayPal email linked to it. We keep records of rewards already paid out, and the ledger entries behind them, as long as tax, accounting, and fraud-prevention rules require, plus aggregated analytics that no longer identify you. Any unpaid reward balance is forfeited, as described in the Platform Terms.

9. California notice

If you are a California resident, you may have rights under the CCPA/CPRA, including the right to know, delete, and correct certain personal information, and to non-discrimination for exercising those rights. Categories of data we may collect that align with our App Store privacy labels and Google Play Data safety section include Advertising Data, Product Interaction, Identifiers, and Other User Content (such as chat messages and images used for AI features). Chat content is used to operate the AI product and is shared with third-party AI providers as described in Section 4; when AdMob is the active network, chat is not used as third-party advertising targeting keywords in the AdMob request. We do not “sell” personal information as that term is commonly understood for cash transactions; some ad / analytics disclosures may be considered “sharing” for cross-context behavioral advertising under California law where applicable.

Do Not Sell or Share My Personal Information. California residents, and residents of other U.S. states with similar privacy laws, can opt out of this sharing at any time. In the cutGPT app, go to Settings → Manage Ad Privacy and choose “Don’t sell or share my data.” After you opt out, ads in the app are no longer personalized using your information. You will still see ads, and opting out does not affect your access to cutGPT or your rewards. You can also email [email protected] with the subject “Do Not Sell or Share” and we will help you complete the opt-out.

To make any other privacy request, contact [email protected].

10. International transfers

We are based in the United States and may process information in the U.S. and other countries. By using the Service, you understand that your information may be transferred to jurisdictions with different data-protection laws than your own.

11. Children

The Service is not directed to children under 13 (or the minimum age required in your jurisdiction), and we do not knowingly collect personal information from children. If you believe a child has provided us information, contact [email protected] so we can delete it.

12. Changes

We may update this Privacy Policy at any time by posting a revised version on this page and updating the “Last Updated” date. Continued use of the Service after changes become effective constitutes acceptance of the updated Policy.
