Privacy Policy — PasteFilter

Last updated: July 20, 2026

Chrome / Edge / Opera Firefox

This Privacy Policy explains how the PasteFilter browser extension by SEOULTRA handles data. PasteFilter is built privacy-first — no data ever leaves your device.

What PasteFilter does

PasteFilter inspects text you actively paste into an editable field, or text you select and clean via the right-click menu. It detects sensitive values (secrets and personal data) and — at your choosing — blocks, masks, or replaces them with fictional data. All of this happens locally in your browser's JavaScript engine.

What we store

Only on your own device, via the browser's built-in storage API (chrome.storage.local / browser.storage.local):

Your settings: mode, per-detector toggles, paused sites, allowlist patterns, and theme.
A local counter of how many items PasteFilter has filtered, by type.

This data is never transmitted, synced to us, or shared.

What we do NOT collect

No browsing history, URLs, or page content.
No keystrokes or clipboard contents beyond the specific text you paste or select for cleaning — and even that is processed locally and never sent.
No IP addresses, device identifiers, or location.
No analytics, telemetry, cookies, or fingerprinting.
No personal information of any kind.

Network requests

PasteFilter makes zero network requests. There are no servers, no SDKs, no third-party services, no ads, and no trackers. Detection and replacement run entirely in local JavaScript.

Permissions explained

storage — Saves your settings and the local counter on your device. Nothing is synced or uploaded.
contextMenus — Adds the "clean this field / selection" right-click item.
Host access (<all_urls>) — Required so paste protection works on any site. It only reads the text you paste or select; no page content is read or collected.

Remote code

PasteFilter does not load or execute any remote code. All JavaScript is included in the extension package.

Data sharing

We do not sell, share, or transfer any data to anyone, because none is collected. Everything stays on your device.

Children's privacy

PasteFilter does not knowingly collect any data from anyone, including children under 13.

Changes to this policy

If we update this policy, the changes will be posted on this page with an updated date. Since the extension collects no data, we do not anticipate material changes.

In short: your data stays on your device. We collect nothing. Detection is 100% local.
