Privacy policy

Privacy Policy

Fullsy is a browser extension that captures full-page screenshots of web pages you choose to capture. This policy is short because there is very little to report. Everything happens on your machine.

What we collect

What we collect

Almost nothing. The Fullsy extension collects no personal information, no browsing history, no analytics, and no telemetry of any kind, and it has no servers. The one thing we collect is your email address, only when you buy Fullsy Pro, and only to send you your license key and receipt (see §06).

What any Fullsy server holds about your captures or browsing: nothing. Your captures never leave your device.
Your captures

How your captures are handled

  • Captures happen only when you explicitly trigger one, by clicking the extension icon, using the keyboard shortcut, or choosing the right-click capture option.
  • All processing happens locally in your browser. Capture, stitching, annotation, analysis, and every export.
  • Your most recent captures (up to 10) are stored in your browser's local storage (IndexedDB) so the results tab and the Archive panel can display them. They never leave your device. The oldest capture is deleted automatically when a new one exceeds the limit, and you can delete any capture yourself from the Archive panel at any time. Uninstalling the extension removes all stored captures.
  • The extension has no servers, makes no network requests of its own, and transmits no data anywhere.
Permissions

Permissions

Three permissions are requested at install. Two more are optional and are requested at runtime, only when you enable the features that need them.

  • activeTab — grants access to the current tab's contents only at the moment you trigger a capture, only for that tab.
  • scripting — used to measure the page and scroll it during capture.
  • contextMenus — adds the "capture this post" and "capture this scrollable area" items to the right-click menu.
  • pageCapture (optional) — requested at runtime, only if you enable the Archive Record's offline-archive feature, to save pages as self-contained files. Never requested at install.
  • Host access (optional) — requested at runtime, only if you switch on agent access, so pages can carry the small bridge your agent talks to. Never requested at install, and the agent toggle turns it back off.
Agent access

Agent access

Fullsy can take capture instructions from AI agents that work inside your own browser. This is off by default. Nothing about it exists until you switch it on, and switching it on shows a runtime permission prompt.

Agent-initiated captures are processed and stored locally, exactly like every other capture. Each one is marked agent-initiated and filed into a case file you can open, download, and delete at any time. Nothing is transmitted anywhere. The same no-server architecture applies.

Pro licensing & trial

Fullsy Pro licensing & trial

Pro license keys are verified entirely on your device using a cryptographic signature check. Activation makes no network request, requires no account, and transmits nothing. Your license key and the email embedded in it are stored locally alongside your captures and are removed when you deactivate or uninstall. The 30-day free trial is tracked by a single timestamp stored on your machine. Nothing about your trial status is transmitted anywhere.

When you buy Pro

When you buy Fullsy Pro

Buying a license is the one time information leaves your device, and only what's needed to sell you a license and deliver it.

  • Your email address — collected at checkout so we can send you your license key and receipt and reach you about your purchase. We keep a record of the sale and the key we issued so we can support and renew it. We don't sell it, we don't share it, and we don't use it for marketing without your consent.
  • Payment details — handled by Stripe, our payment processor and merchant of record. We never see or store your full card details; Stripe's handling of payment data is governed by Stripe's own privacy policy.
  • Email delivery — your license key and receipt are sent through Resend, our email provider, which processes your email address only to deliver that message. Resend's handling is governed by its own privacy policy.

The extension itself stays on-device. None of your captures, browsing, or activity is ever part of this.
