GPT to PDFby 1LightYear Labs

Privacy Policy

Last Updated: September 15, 2026

🔒 Your privacy in plain English:GPT to PDF does not collect your conversations or any personally identifiable information. Every PDF and Word file is built on your own device. The App uses Firebase Analytics for anonymous usage insights, Google AdMob (with Meta Audience Network) to show advertisements, and RevenueCat with Google Play Billing or the Apple App Store to manage purchases.

1. About This Policy

  • This Privacy Policy describes how 1LightYear Labs ("we", "us", or "our") handles information when you use the GPT to PDF mobile application ("App") on Android and iOS.
  • 1LightYear Labs is a trading name of Chaitanya Sharad Mogal, a sole proprietor based in Nashik, India, who is the data controller for the purposes of this policy.
  • By using the App, you agree to the practices described in this policy. If you do not agree, please do not use the App.

2. Information We Collect

  • We do not collect any personally identifiable information. The App does not require you to create an account, log in, or provide any personal details.
  • We do not collect your name, email address, phone number, or the content of your ChatGPT, Google Gemini or Claude conversations.
  • Analytics: We use Firebase Analytics (by Google LLC) to collect anonymous app-interaction data: which screens you view (including paywall views), steps in the purchase flow, how many messages an export contained, which chat service it came from, and general feature usage. Firebase assigns an anonymous analytics identifier to your device. This data is not linked to your name, email, or any other identifying information, and it never includes the contents of a conversation, a share link, or a generated file.
  • Configuration: We use Firebase Remote Config (by Google LLC) to tell the App whether a newer version is available. This sends only the standard request metadata Google requires to deliver a configuration file.
  • Advertising: We use Google AdMob (by Google LLC) to display advertisements. Google may collect and use certain data to serve and measure ads, including advertising identifiers, IP address, coarse location derived from IP, and ad-interaction data. This is governed by Google's Privacy Policy (https://policies.google.com/privacy).
  • Ad mediation: The App also uses Meta Audience Network (by Meta Platforms, Inc.) as part of our ad mediation setup. When a Meta ad is shown, Meta may collect ad request and interaction data - device identifiers, IP address, ad engagement - to serve and measure advertisements. This is governed by Meta's Privacy Policy (https://www.facebook.com/privacy/policy/).
  • Purchases: If you buy a subscription or the lifetime unlock, your purchase and subscription data (purchase receipts, product identifiers and subscription status) is sent to RevenueCat, Inc., which we use to manage your entitlements. RevenueCat assigns an anonymous app user ID. We never receive or store your name, email address, or payment card details. Payments are processed entirely by Google Play on Android and by Apple on iOS.
  • Advertising ID: On Android the App declares the com.google.android.gms.permission.AD_ID permission so that the advertising SDKs above can request ads. You can reset or delete this identifier at any time in Settings > Google > Ads.
  • Apple's App Tracking Transparency (iOS): On iOS the App asks, through Apple's system prompt, whether you allow tracking across apps and websites owned by other companies. If you allow it, our advertising partners may use Apple's Identifier for Advertisers (IDFA) to serve and measure ads. If you decline, the App keeps working exactly the same - you will still see ads, they will simply be less relevant. You can change your answer at any time in Settings > Privacy & Security > Tracking.
  • Paying subscribers ("Pro") are shown no advertisements at all, so none of the advertising data flows above apply to them while their entitlement is active.

3. Consent for Advertising (EEA, UK and Switzerland)

  • Where the GDPR or equivalent laws apply, the App presents a Google-certified consent message (Google's User Messaging Platform) before any ad is requested, and it records your choices in the industry-standard IAB Transparency and Consent Framework format.
  • If you consent, ads may be personalised. If you do not, the App requests non-personalised ads instead. Either way, the App remains fully usable.
  • You can change your mind at any time: open Settings > Ad Privacy Options inside the App. That row is shown wherever a consent choice is required.
  • Outside those regions no consent signal is required by law, and ads may be personalised subject to your device settings (and, on iOS, your App Tracking Transparency answer).

4. How the App Works

  • The App works only with public share links that you create yourself in ChatGPT, Google Gemini or Claude and then paste into the App (or send to it from another app's share sheet). It cannot open your private chats, and it never signs in to any account.
  • To read a shared chat, the App requests that public page directly from the chat provider's servers - chatgpt.com, gemini.google.com or claude.ai - either with a direct HTTPS request or by loading the page inside a WebView within the App, and then reads the visible conversation from it.
  • If the conversation contains images, those images are downloaded from the chat provider's own content servers so they can be placed into your document.
  • All file generation - PDF and Word (DOCX) - happens entirely on your device.
  • We operate no servers of our own. No conversation content, no share link, and no generated file is ever sent to us, and we have no ability to see any of them. The only outbound connections the App makes are to the chat provider you chose, and to the Google, Meta and RevenueCat services named in Section 2.

5. Where Your Files and History Live

  • Exported PDF and Word files are written to your device's app storage, and to your Downloads folder only when you tap Download (Android) or choose a location yourself in the Files app (iOS).
  • Your export history - file names, sizes, dates and the share link each export came from - is stored locally on your device only. It is never uploaded.
  • Deleting an export inside the App, or uninstalling the App, removes this data from your device. Because we never receive it, there is nothing for us to delete on our side.

6. App Permissions

  • The App may request the following on your device, and uses each only for the stated purpose:
  • Internet access - required to load the public share page you asked to convert, to download the images in it, and to serve ads and validate purchases.
  • Storage access (READ_EXTERNAL_STORAGE / WRITE_EXTERNAL_STORAGE, on Android 9 and older only) - used solely to save a generated file into your Downloads folder when you ask for it. On Android 10 and newer this permission is not requested or required. We never read any other file on your device.
  • Notifications (POST_NOTIFICATIONS, Android 13 and newer) - used solely to show a "Download complete" notification after you save a file. Declining it does not affect any other feature. The App sends no marketing or push notifications of any kind.
  • Advertising ID (com.google.android.gms.permission.AD_ID, Android) - used only by the advertising services described in Section 2.

7. Data Sharing

  • We do not sell or rent your data to anyone. We do not share your data with anyone for cross-context behavioural advertising of our own.
  • Anonymous app-interaction and configuration data is shared with Google LLC through Firebase Analytics and Firebase Remote Config, solely to understand how the App is used and to deliver update notices.
  • Ad-related data may be shared with Google LLC (Google AdMob) and Meta Platforms, Inc. (Meta Audience Network) for the purpose of serving and measuring advertisements. We do not control what these companies collect for advertising; that is governed by their own privacy policies.
  • Purchase and subscription data is shared with RevenueCat, Inc., which acts as our service provider, solely to validate and manage your entitlements. It is not used for advertising or marketing.
  • Payment data is handled entirely by Google LLC (Google Play Billing) or Apple Inc. (App Store), never by us.
  • We may disclose information if required to do so by law. In practice we hold no personal data that could be disclosed.

8. Third-Party Services

  • Your use of the following is governed by their own terms and privacy policies. We are not affiliated with, endorsed by, or partnered with any of them.

9. International Transfers

  • The third-party services listed above are operated by companies based in the United States and may process data in countries other than your own. Where required, those companies rely on their own approved transfer mechanisms (such as the EU Standard Contractual Clauses).
  • Because we neither collect nor store personal data ourselves, we carry out no international transfers of our own.

10. Data Retention

  • We retain no personal data, because we collect none.
  • Anonymous analytics data is retained by Google according to the Firebase retention period configured for our project and Google's own policies.
  • Purchase records are retained by RevenueCat, Google and Apple for as long as they need them to provide and account for your purchase.
  • Your exports and history remain on your device until you delete them or uninstall the App.

11. Your Rights

  • Depending on where you live, you may have rights under the GDPR, the UK GDPR, the CCPA/CPRA or the DPDP Act to access, correct, delete or port your personal data, and to object to certain processing.
  • Because we do not collect or store personal data, we hold nothing to provide, correct or delete. For the anonymous advertising and analytics data held by the companies in Section 8, please use the controls they provide, the in-App Settings > Ad Privacy Options row, or your device's advertising settings.
  • We do not "sell" or "share" personal information as those terms are defined under California law.
  • If you have any concern, write to us at [email protected] or [email protected] and we will help.

12. Children's Privacy

  • The App is not directed to children. It is intended for users aged 13 and over, or 16 and over in any country whose law sets that as the minimum age for consent to data processing (as several EU member states do).
  • We do not knowingly collect personal information from children. The App is not listed in any store's children's or families programme, and we do not knowingly serve ads to children.
  • If you believe a child has used the App and provided personal information, contact us at [email protected] or [email protected] and we will act promptly.

13. Data Security

  • Because we do not collect or transmit personal data to any server of ours, there is no user data on our side to secure.
  • All network requests the App makes use HTTPS.
  • Generated files are saved only to your device's local storage and remain under your control.

14. Changes to This Policy

  • We may update this Privacy Policy from time to time. When we do, we will update the 'Last Updated' date at the top of this page.
  • We encourage you to review this policy periodically. Continued use of the App after changes are posted means you accept the updated policy.
