Privacy Assurance

Privacy Policy

Last Updated: November 2026

🔒 Core Architectural Privacy Guarantee

FilePeek does not upload, transmit, store, or inspect your files on any remote server. All file parsing, decompression, and previewing happens 100% locally on your computer or mobile device using native browser Web APIs. When you close the browser tab, all file memory references are immediately revoked.

1. Information We Do NOT Collect

Unlike conventional online document converters and file viewers, FilePeek operates strictly as a client-side utility:

  • File Contents: Your files never leave your device. We do not transmit or cache file data.
  • File Names & Metadata: We do not log, track, or collect the filenames, metadata, or paths of files you open.
  • User Accounts & Identities: FilePeek requires no registration, username, email address, or payment details.

2. Advertising & Third-Party Cookies (Google AdSense Compliance)

To keep FilePeek 100% free for users worldwide without charging subscription fees, we display advertisements provided by Google AdSense and third-party advertising networks.

Google AdSense & DoubleClick DART Cookies:

  • Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites on the internet.
  • Google's use of advertising cookies enables it and its partners to serve ads to users based on their visit to our site and/or other sites on the internet.
  • Users may opt out of personalized advertising by visiting Google Ads Settings.
  • Alternatively, users can opt out of third-party vendor use of cookies for personalized advertising by visiting www.aboutads.info/choices or the Your Online Choices opt-out guide.

3. Local Device Storage & Session Hygiene

FilePeek does not store uploaded document data in persistent browser storage such as localStorage, IndexedDB, or sessionStorage.

Temporary in-memory blobs (created via URL.createObjectURL) are tracked in our session lifecycle manager and explicitly destroyed with URL.revokeObjectURL when tabs are closed.

4. Server-Side Immunity & Infrastructure

Our hosting server only delivers static application bundles (HTML, CSS, JavaScript, WebAssembly workers) via HTTP GET and HEAD requests. The server rejects all POST, PUT, or file upload attempts with 405 Method Not Allowed. There is no server-side script execution or file processing backend.

5. Analytics & Telemetry

We may utilize privacy-respecting website analytics to track aggregated page visit counts, browser types, and geographic regions to optimize performance. Telemetry never captures file contents, document text, or identifiable user records.

6. European Privacy Rights (GDPR)

Under the European Union General Data Protection Regulation (GDPR), users within the European Economic Area (EEA) have rights concerning personal data processing. Because FilePeek does not collect personal identifiers or file payloads, we do not maintain identifiable records of your document activities.

7. California Consumer Privacy Act (CCPA)

Under CCPA, California residents have the right to know what personal data is collected and request deletion. FilePeek does not sell, rent, or monetize your personal information or file contents.
