Privacy Policy

Effective date: October 17, 2026 · Last updated: October 17, 2026

This policy explains what data the PDF Xtension Chrome extension (“PDF Xtension”, “the extension”) handles, why, and what you can do about it. PDF Xtension is published by Obzena LLC, 30 N Gould St #45213, Sheridan, WY 82801, USA (“we”, “us”).

1. Data we handle

Data	Why	Where it goes
Your PDFs and images	To run the tool you chose	Processed in your browser only; never uploaded
Text of the pages you translate (text blocks and their page number)	To translate it	Our server (Google Cloud / Firebase) and OpenAI's API
Installation ID (random, created on install)	To link your plan to this browser and count AI pages	Stored in the extension and on our server
Plan and billing status (plan, renewal date, Stripe customer and subscription IDs)	To unlock the extension	Our server, from Stripe
Email address you enter at Stripe checkout	Receipts, and the code for “Restore purchase”	Stripe and our server
AI usage (pages translated per period, token counts, cost)	To enforce plan limits and prevent abuse	Our server

The extension does not collect your browsing history, the content of web pages you visit, your location, or analytics about how you use it.

2. Files and local processing

PDF Xtension uses the open-source libraries pdf.js and pdf-lib, bundled inside the extension, to read and write PDFs in your browser. A PDF you open from a browser tab is downloaded by your browser into the extension's page, used for the tool you chose, and briefly kept in the extension's local storage (IndexedDB) only to hand it from the toolbar menu to the tool page; it is deleted as soon as the tool page opens it.

3. AI translation

1. In your browser, the extension reads the text of the pages you chose and its position on the page.
2. Only the text blocks (for example “Annual report 2026”) with an internal block number are sent over HTTPS to our server, which checks your plan and forwards them to OpenAI's API. Positions, images and the file stay on your device.
3. The translated text comes back and the extension draws it into the same places on the page, in your browser.

OpenAI acts as our service provider. Under its API terms, data sent through its API is not used to train its models by default and is deleted after a limited retention period (up to 30 days). We keep the translated text of each request for 24 hours so that a retried request is not charged twice, then it is deleted automatically.

4. Payments and your plan

When you choose a plan, Stripe's checkout page opens in a new tab. Stripe processes your payment and shares with us the subscription status, plan, renewal date and the email you entered. We never receive your full card number. Stripe's privacy policy: stripe.com/privacy.

5. Browser permissions

• activeTab: only after you click the PDF Xtension toolbar button (or its shortcut), lets the extension read the address of the current tab and, if it is a PDF and you choose a tool, download that PDF into the extension.
• storage: keeps your installation ID and plan status in the browser.
• Access to our server (us-central1-obzena-extensions.cloudfunctions.net): plan checks and AI translation.

6. Service providers

• Google Cloud / Firebase (server and database): firebase.google.com/support/privacy
• OpenAI (AI translation): openai.com/policies/privacy-policy
• Stripe (payments): stripe.com/privacy

We may also disclose data if required by law or to protect the rights and safety of our users or of Obzena LLC.

7. Retention and deletion

• Files: never stored by us.
• Translated text: 24 hours on our server.
• Plan, installation ID, usage counts, email: while your subscription is active and up to 24 months after it ends, or longer where tax and accounting law requires it for payment records.

Removing the extension deletes the data stored in your browser. To delete the data on our server, email hello@obzena.com with the subject “PDF Xtension data deletion” and the email you used at checkout; we delete it within 30 days. Deleting data does not cancel a subscription; see the Support page for how to cancel.

8. Your rights

Depending on where you live (for example under the GDPR, UK GDPR, CCPA/CPRA or KVKK), you may have the right to access, correct, delete, export or restrict the processing of your personal data, and to object to processing. Contact us at hello@obzena.com; we respond within 30 days. You may also complain to your local data protection authority. Our legal bases (where the GDPR applies) are performance of our contract with you and our legitimate interests in security and abuse prevention.

Our providers process data in the United States and other countries. Where required, transfers rely on safeguards such as the European Commission's Standard Contractual Clauses. Data is encrypted in transit (HTTPS/TLS).

9. Chrome Web Store Limited Use

The use of information received from Chrome APIs complies with the Chrome Web Store User Data Policy, including the Limited Use requirements. We use data only to provide the extension's single purpose (working with PDF files and translating them), we do not sell it, we do not use it for advertising or creditworthiness, and humans do not read it except with your permission, for security, or to comply with the law.

10. Children, changes and contact

PDF Xtension is not directed at children under 13 (or the minimum age in your country). We may update this policy when the extension changes; the current version is always on this page, with the date at the top.
