Your Privacy by Bookcicle

Name: Your Privacy by Bookcicle
Author: Bookcicle Labs

A lightweight, transparent browser extension that calculates an empirical privacy score for every webpage you visit. Engineered with 100% local-only execution, zero telemetry by default, no user accounts, and deterministic scoring.

100% Local-Only

All network request audits, cookie classifications, and scoring calculations happen strictly inside your browser memory and local storage.

Zero-Tracking Philosophy

No surveillance, no cookies, no advertising IDs, and no accounts. Zero telemetry by default—your browsing history never leaves your device.

Deterministic Math

No subjective black-box ratings. Transparent deductions for third-party domains, trackers, cookies, and session replay recorders.

The Scoring Algorithm

Every page starts at a perfect baseline score of 100. Deductions are assessed deterministically for external tracking vectors:

Third-Party Domains: -5 points per external domain outside the site's primary registered origin.
Known Ad & Behavioral Trackers: -15 points per identified advertising or tracking signature.
Cross-Site Tracking Cookies: -8 points per external domain setting or transmitting cookies.
Invasive Session Replay: -25 points for script-based session recording (e.g., Hotjar, Contentsquare, FullStory).

Scores are clamped between 0 and 100, mapped to intuitive visual bands: 80–100 (Good), 50–79 (Moderate), and 0–49 (Poor).

Privacy Controls & Settings

The extension provides granular, user-first controls:

Community Defense (Opt-in)

Strictly anonymized, weekly deduplicated reports (maximum 1 per domain per week) to compile transparent web privacy audits without identifying individual users.

Page Journeys (Opt-in)

Anonymous path transition graph edges with fully sanitized route identifiers (/:id/, /:uuid/) to observe tracking patterns without user session stitching.

Bookcicle Zero-PII Guarantee

Your Privacy operates locally in your browser with zero telemetry by default. When Community Defense or Page Journeys are voluntarily enabled, observation packets contain only aggregated tracker counts, letter grades, sanitized paths, and anonymous previous-step transitions. No cookies, auth headers, browser fingerprints, session tokens, IP addresses, or personal identifiers are ever stored or transmitted.

The useful details

Questions, answered.

Can I write without an internet connection?

You can continue drafting and editing locally. Cloud sync, shared collaboration, and cloud-backed AI features require connectivity.

What does “native editor” mean?

The Studio Editor runs as part of the native desktop application, using native panes, windows, input, and persistence while remaining compatible with your Studio projects.

Can I use Studio without installing the desktop app?

Yes. Studio Editor for the web provides a lighter version of the authoring experience in a modern browser. Use Desktop when you want the full native workspace, offline-ready writing, Capture, and local Notary tools.

Does AI replace my authorship?

No. AI is a collaborator you direct. Bookcicle is designed to keep the author in control and preserve meaningful contribution history around the work.

What does Notary prove?

Notary creates cryptographic proof records for exact content states. It can help demonstrate that a specific version existed at a point in the work’s history; it is not a substitute for a commissioned notary public.

Your next draft deserves a better environment.

Start in the browser or settle into the native workspace. Your work remains at the center.
