This policy explains how Scanner STK handles accounts, your document library, optional cloud storage, advertising, purchases and Chat STK. It is part of the STK privacy information.
1. Accounts and service information
Scanner STK offers an app account. Account identifiers, information you provide to sign in, support messages, technical information and purchase records may be processed to operate the service, recognise access and respond to requests.
2. Document storage and device processing
Your document library is stored on your device or, if you choose, in your own iCloud or Google Drive account. It is not hosted as a document library in STK storage. Ordinary text extraction and search take place on the device. Your own cloud provider handles files saved to that account under its policies.
3. Chat STK — Cloudflare and Groq
AI requests are routed through STK’s Cloudflare server to Groq. A normal message includes your question and the recent part of the conversation context. An image request includes the image you select, the question and context. A PDF request includes an image of its first page and extracted text, rather than the entire original PDF. Other files are not sent automatically. Processing selected content for AI is separate from storing your library.
4. Why selected content is processed
The selected content and conversation context are processed to answer your document questions. Cloudflare and Groq process the request as service providers. Their policies and the service configuration govern provider processing and retention. See Groq’s data documentation, Groq’s privacy policy and Cloudflare’s privacy policy.
5. Permissions and your cloud choices
Scanning, importing and saving use the camera, files and cloud access you choose to allow. You control access through app permissions, device settings and your cloud account. Disconnecting a cloud service does not automatically delete files already stored there. Only select documents you intend to use with Chat STK.
6. Advertising and purchases
Scanner STK contains advertising and in-app purchases. Advertising services may process device identifiers, ad interactions, IP addresses and diagnostics according to permissions, privacy choices and provider configuration. Purchases are processed through Apple App Store or Google Play. Product identifiers, transaction references and purchase status may be used to recognise purchases and provide support.
7. Retention and deletion
Manage local documents on your device and cloud copies in your own cloud account. Contact STK to request deletion of your Scanner STK account and identifiable personal data STK controls. Limited account, transaction, security or legal records may be retained where necessary. Deleting an app account does not automatically erase personal cloud copies or records independently held by Apple, Google, Cloudflare or Groq. Provider retention depends on the relevant service and settings.
8. Your rights and contact
Depending on applicable law, you may request access, correction, export, restriction, objection or deletion. Contact STK with the app name and account identifier where available. Verification may be required. Do not attach private documents to a support request unless they are necessary and you intend to share them.
For privacy and data requests, email contact@exstk.com. Do not send passwords, verification codes or payment card details.
