Short version: Your browsing data stays on your device. Tab info, settings, the health-score history, saved sessions, and your block list are stored locally in your browser. We do not have a server that receives them, and we never sell or share them. Data leaves your device only when you run a speed test or choose to subscribe to Pro — both explained below.
What the extension stores locally (on your device only)
- Open-tab counts/titles/URLs used to show stats and find tabs (read live, not sent anywhere).
- System RAM/CPU samples used for the gauges, badge, and history graph.
- Per-tab last-active timestamps used for "stale tab" detection and auto-suspend.
- Your settings (auto-suspend preferences, scheduled speed test).
- Saved sessions you create.
- Your site block list.
This information is kept in chrome.storage on your computer. It is
not transmitted to us and there is no account or cloud sync.
When data leaves your device
1. Internet speed test
When you run a speed test (or, on Pro, when a scheduled test runs), the
extension downloads/uploads test data to Cloudflare's public speed-test endpoint
(speed.cloudflare.com). As with any web request, Cloudflare receives
your IP address and connection metadata. We do not receive or store the results on
any server — they are shown to you and kept locally. See Cloudflare's privacy
policy for how they handle requests.
2. Pro subscription (optional)
Payments are handled by ExtensionPay and Stripe. If you subscribe, you provide your email and payment details directly to them; we never see or store your card information. ExtensionPay stores your email and subscription status so the extension can verify whether Pro is active. See ExtensionPay's and Stripe's privacy policies for details.
What we do NOT do
- We do not collect or transmit your browsing history. (The extension does not request the browsing-history permission.)
- We do not use analytics or tracking SDKs.
- We do not sell, rent, or share your data with advertisers.
- We do not run a server that receives your tabs, usage, or block list.
Site blocking
The block list you create is used only to block those sites in your own browser, via Chrome's declarativeNetRequest API. The list stays on your device.
Permissions and why they're used
tabs/tabGroups— tab stats, search, duplicate/stale detection, auto-suspend.system.cpu/system.memory— show RAM/CPU usage and the health score.storage— save your settings, history, sessions, and block list locally.alarms— periodically sample system stats and run scheduled speed tests.declarativeNetRequest— block the sites on your block list.- Host access to
speed.cloudflare.com— run the speed test. - Host access to
extensionpay.com— verify your Pro subscription status.
Data retention & deletion
All local data lives in your browser. Removing the extension deletes it. You can also clear individual items in the popup (remove sessions, unblock sites, etc.). To delete your ExtensionPay subscription data, cancel your subscription and contact ExtensionPay.
Children
The extension is not directed to children under 13.
Changes
We may update this policy; the "Effective date" above will change accordingly.
