SourceBox — Privacy Policy

Last updated: 2026-07-15 · Beta

SourceBox lets you close all your browser tabs in one click without losing them: every tab is saved first, and shown back to you in your SourceBox inbox. This policy explains exactly what data that involves.

What we collect

• Closed-tab data. When you click “close all tabs,” SourceBox records each tab’s URL, page title, and favicon URL, plus the time, browser window, browser, and device it was closed on. This is the core function of the product.
• Your email address. Used only to sign you in with a one-time code and to associate your saved tabs with your account.

SourceBox does not read page content, browsing history, bookmarks, keystrokes, or anything beyond the tabs you explicitly choose to close. It requests only the tabs, storage, and alarms browser permissions and access to its own backend.

How your data is used

Solely to save your closed tabs and show them back to you in your inbox. We do not use your data for advertising, profiling, or any purpose other than delivering the product to you.

Where it’s stored

Tabs are saved locally in your browser first. When you’re signed in, they also sync to a hosted database (Supabase) under your account, isolated by row-level security so that only you can access your data. Sign-in emails are sent via an email provider (Resend). These providers process data on our behalf and are not permitted to use it for their own purposes.

What we don’t do

• We never sell or rent your data.
• We don’t share it with third parties except the processors above.
• No analytics, ad tracking, or third-party trackers.

Retention & deletion

Your saved tabs are kept so you can find them later. During the beta, to delete your account and all associated data, email the address below and we’ll remove it promptly.
