Privacy Policy

Effective date: November 4, 2026 · App: ScanMind AI (package com.otjhllc.scanmind)

This Privacy Policy explains how OTJH LLC ("we", "us") handles information when you use the ScanMind AI mobile application and website (the "App"). We built the App so that your documents stay on your device by default.

1. Summary

• No account is required. We do not ask for your name, email or phone number.
• Your scans and documents are stored only on your device.
• The App contains no advertising and no third-party analytics or tracking SDKs.
• Document content leaves your device only when you use an AI feature, and only to answer your request.
• We do not sell or share your personal information for advertising.

2. Information processed on your device

Camera. The App uses your camera only while the scanner is open, to capture documents and read QR codes. Images are processed on your device (edge detection, cropping, filters).

Files and photos you import. Files you choose (images or PDFs) are converted and stored inside the App's private storage on your device.

Text recognition (OCR). Text recognition runs on your device. The first time you use it, the App downloads language data files (see section 4).

Signatures, settings and chat history. Your saved signature, preferences and AI chat history are stored locally on your device.

We cannot access any of this information. It is deleted when you delete it in the App ("Settings → Delete all documents") or uninstall the App.

3. AI features

When you use "Ask AI", "Summarize", "Translate" or other AI features, the App sends the following to our server, which forwards it to our AI provider to generate the answer:

• images of the pages of the selected document (up to 10 pages) and its extracted text, if any;
• the document name;
• your messages in that chat and the previous answers in the same chat;
• your selected app language.

Our AI provider is OpenAI, L.L.C. (OpenAI API). OpenAI processes this data on our behalf under its API business terms, does not use API data to train its models by default, and keeps it only for a limited period for abuse monitoring and legal purposes as described in OpenAI's Privacy Policy and API data commitments.

Our server runs on Cloudflare, Inc. (Cloudflare Workers), which hosts it on our behalf. It does not store your documents or messages: it processes them in memory only for the duration of the request. To prevent abuse, the server keeps the IP address of each request in memory for up to 10 minutes for rate limiting, and logs technical error codes that do not contain document content.

ScanMind AI Pro. AI features are available to ScanMind AI Pro subscribers. To confirm your subscription and apply your plan's monthly AI allowance, the App sends your Google Play purchase token with each AI request. Our server checks the token with Google Play to confirm the subscription is active and which plan it is, and stores only a one-way hash of it together with the AI usage of the current month. Payments are processed by Google Play; we never receive your card or payment details.

Reported answers. If you use "Report" on an AI answer, the App sends that answer, the question before it, the optional reason you type and the app language to our server, where they are stored so we can review the report and improve the service.

Before your first AI request the App asks for your permission. If you do not use AI features, no document content leaves your device. Do not use AI features with documents you are not permitted to share.

4. Network requests to service providers

To keep the App small, some components are downloaded when first needed: PDF, Word and text-recognition libraries and language data from cdnjs.cloudflare.com and cdn.jsdelivr.net, and fonts from Google Fonts. As with any internet request, these providers receive your device's IP address and basic technical information (such as the user agent). No document content is sent to them.

5. Sharing

We share information only with the service providers described above (OpenAI to generate answers, Cloudflare to host our server, Google Play for subscriptions), when you use AI features, and when required by law. When you use "Share", "Download" or "Save", files are passed to the app or destination you choose, under that service's own policy.

6. Security

Data sent to our server is encrypted in transit (HTTPS). Documents on your device are stored in the App's private storage, protected by your device's security. The optional PDF password feature encrypts exported PDFs; use a strong password.

7. Data retention and deletion

Documents remain on your device until you delete them. You can delete a single document, all documents (Settings → Delete all documents) or uninstall the App. Because we do not store your documents or messages on our servers, there is no server-side copy for us to delete. Usage counters are reset every month; reported answers are kept only as long as needed to review them. To delete them, email us with your request.

8. Children

The App is not directed to children under 13 (or the minimum age in your country). We do not knowingly collect personal information from children.

9. Your rights

Depending on where you live (for example under the GDPR or CCPA/CPRA), you may have rights to access, correct, delete or object to processing of your personal information. Because your data stays on your device, you can exercise most of these rights directly in the App. For any request, contact us at the address below.

10. International transfers

When you use AI features, data may be processed in the United States or other countries where our server and OpenAI operate, with appropriate safeguards.

11. Changes

We may update this policy. We will change the effective date above and, for material changes, notify you in the App.
