What
we know,
and don’t.

Plain
language

UnifyBrowse is built and maintained by a small independent studio. This page explains what data is collected, how it’s used, and how it’s handled across the website and the browser extensions. In plain language.

§01Philosophy

The approach is simple: charge for premium software features, and nothing else. Your personal data is never sold to third parties. Extensions are designed to operate locally on your device whenever possible.

Cloud sync exists only for features that genuinely need it, and you have to opt into them. The default is local. The default is anonymous.

§02Information collected

When you use the website or open an account, the following may be collected:

  • Account informationEmail address and basic profile details required for authentication.
  • Billing detailsIf you purchase a Pro plan — whether a one-time lifetime payment or a recurring subscription — payment processing is handled by Lemon Squeezy, our Merchant of Record. Full card numbers are never seen or stored by us — Lemon Squeezy handles the entire payment flow, recurring billing, and tax compliance.
  • Support requestsIf you contact support from within an extension, we receive the message you write and — only if you choose to provide it — a reply email address, used solely to respond to you.
  • Contact formIf you use the website contact form, we store your name, email, subject, and message so we can reply. Submissions are protected by anti-spam verification and used only to respond to you.
  • Anonymous analyticsPer-extension event names, anonymous instance IDs, timestamps. No personally identifiable information.
§03Per-extension specifics01 entries

Each extension requests only the permissions it genuinely needs. Below is a per-extension breakdown.

01

Cairn#

· Permissions

storage: Stores Cairn settings and reading progress locally. unlimitedStorage: Lets the local IndexedDB library grow beyond the browser’s default quota. contextMenus: Provides right-click actions to save pages, selected text, images, and links. activeTab: Reads the current tab only after the user explicitly triggers a save action. scripting: Injects the metadata and article extractor into the active tab only when the user saves it.

· Data handling

Saved items, article HTML, highlights, notes, tags, collections, and reading progress remain on the user’s device. Cairn does not upload this library content to UnifyBrowse.

§04Third-party services

UnifyBrowse relies on a small set of vetted providers to operate. Each handles only what they need to:

  • Lemon SqueezyPayment processing, tax handling, and license-key management. Operates as Merchant of Record for purchases. See lemonsqueezy.com/privacy.
  • SupabaseDatabase and authentication. Stores account credentials, license records, and anonymous analytics.
  • Hosting (Vercel / Cloudflare)Serves the website and forwards extension API traffic.

Personal data is never sold or shared with advertisers. Data is retained only for as long as your account is active, and is deleted within 30 days of account closure.

§05Data protection
  • All data transmitted uses HTTPS encryption.
  • Database access is restricted by Row-Level Security policies; the studio cannot read your private data outside its specific feature scope.
  • Authentication is handled with industry-standard JWTs.
§06Your rights

You can access, modify, or permanently delete your personal data at any time. The dashboard offers a single button that removes your account and any associated cloud data. Local extension storage can be cleared from your browser’s extension panel.

§07Changes to this policy

This policy is updated when the extensions, the studio, or legal requirements change in a meaningful way. The current version is always posted here with a “last updated” date, and significant changes are announced through in-extension notifications — we don’t email you, because we don’t collect your email.
