TabCellar stores your tab and session data only in your own browser, on your own device. We do not upload it to a server, we do not track your browsing, and we do not sell data. There is no TabCellar account and no TabCellar database of your tabs.
To do its job, the TabCellar extension reads the titles and URLs of the tabs you save, and stores your saved tab groups, backups and settings in Chrome's local extension storage on your device. Backups older than 7 days are deleted automatically.
Previous-session recovery. So that you can get your tabs back after your browser closes or crashes, TabCellar also keeps a local list of the URLs and titles of the tabs that are open in your browser windows. This list stays on your device, is replaced as you browse, and up to three previous sessions are kept until you dismiss them. You can switch this off at any time in the extension's settings ("Remember open tabs so I can recover my previous session"); switching it off immediately stops the recording and deletes the list and any kept previous sessions.
This data:
Exports you create (manually or, on Pro, on a schedule) are files downloaded through your browser to your own device. What you do with those files is up to you.
Limited Use. TabCellar does not sell or transfer user data to third parties, does not use or transfer user data for purposes unrelated to saving, restoring and protecting your tabs, and does not use user data to determine creditworthiness or for lending. No one at Lukas Labs can read your tab data, because it never leaves your device.
If you buy TabCellar Pro, payment is handled by our payment processor, which acts as merchant of record. The processor collects the payment details needed to complete your purchase (such as your name, email address and payment method) under its own privacy policy. We receive a confirmation that a licence is active — we do not receive or store your full payment card details. Licence validation checks are limited to verifying that a Pro licence is valid; they do not include any of your tab or browsing data.
