Privacy policy
Tabby browser extension · Effective October 7, 2026
Short version: Tabby never collects, sells or transmits your tabs, links or browsing. Everything you save stays on your device. There is no account, no analytics and no tracking. If you try or buy Tabby Pro, only a random install ID and your plan are checked with our license server (details below).
What Tabby stores, and where
To work, Tabby stores the following only in your browser, on your device (IndexedDB and extension storage):
- Links you choose to save: their URL, title and (on Firefox) icon URL, organized into your spaces and collections.
- Automatic session snapshots: the URLs, titles and tab groups of your open windows, kept for 14 days so you can restore closed windows.
- Settings such as theme, view and your last-used space.
None of this is sent to the developer or to anyone else.
Tabby Pro (only if you start a trial or buy)
- Payments are handled by our reseller Paddle.com, which collects your name, email, payment details and country to process the order and tax. We receive your email, country and order details from Paddle; we never see your card.
- Checking your plan: Tabby creates a random install ID (not linked to your identity or browsing) and asks our license server whether that ID or your license key has an active Pro plan. The server stores the install ID, your license key, the plan and its end date, and Paddle's order and subscription IDs: no name, no email, nothing about your tabs.
- Free users: no license check is made and nothing is sent.
Network requests
- Opening a saved link loads that website, as any link would.
- Site icons: on Chrome and other Chromium browsers, icons come from the browser's local icon cache — no request is made. On Firefox, an icon may be loaded from the website it belongs to.
- Tabby Pro: the plan check described above.
- Tabby makes no other network requests. It contains no remote code, ads, analytics or third-party SDKs.

- Delete links, collections or spaces; they move to Trash, and "Empty trash" removes them permanently.

Children
Tabby does not knowingly collect information from anyone, including children.
Changes
