Privacy Policy

Last updated: February 2026

GlossLink is a desktop Chrome browser extension (no mobile, no native app) built around a simple principle: your glossary belongs to you. We collect as little as humanly possible.

What we collect

Nothing personal. We do not collect names, emails, IP addresses, browsing history, page text, location, or device fingerprints.

What stays on your device

• Your uploaded glossary CSV (term, definition, industry) — saved in chrome.storage.local
• Your preferences (active glossary, auto-detect toggles, PDF reader on/off)
• Your trial start date (a single ISO timestamp set when you install)

None of this is transmitted anywhere unless you take an explicit action below.

When data does leave your device

• You click “Share link.” The active glossary's CSV is sent to our backend (glosslink.app) and stored against a random 8-character ID so others can open it. No personal data attached.
• You enable Auto-detect. Individual unknown words (never page text, never URLs) are sent to public dictionary APIs to fetch a definition: Free Dictionary API, Wikipedia, and Wiktionary. These are public, free services with their own privacy policies.
• You purchase Pro. Payments are processed by our payment provider ExtensionPay and the underlying card processor Stripe. They receive your name, email, billing country, and the last 4 of your card. We receive only your subscription status (paid / unpaid) and your email for receipts.

What we don't do

• No analytics SDKs, no Google Analytics, no Mixpanel, no Segment.
• No advertising. No ad networks. No cookies on the extension itself.
• No selling or sharing of any data with third parties.
• No remote code execution — every script ships inside the extension package.

Permissions explained

• storage — save your glossary locally so it survives browser restarts.
• activeTab — tell the current tab to refresh after you load a new glossary.
• contextMenus — the optional “Define with GlossLink” right-click menu.
• webNavigation, tabs — detect when you open a PDF so we can route it to our PDF reader (only when you've enabled that toggle).
• host_permissions: <all_urls> — required because your glossary might match terms on any website you visit. We only read visible text in-memory to find matches; nothing is exfiltrated.

Your rights

Right-click the GlossLink icon → “Remove from Chrome” and every byte we ever held about you is gone. If you've made a Pro purchase, email [email protected] to request deletion of your billing record.
