What Data Tabber Collects
Privacy
Tabber does not collect personally identifiable information such as your name, email, or account details.
Usage Analytics
When analytics are enabled, Tabber sends the following events and data to Google Analytics:
Tabber Opened | Number of open windows, browser tabs, and Explorer tabs; time in milliseconds for the UI to become visible after Alt-Tab |
App Activated | How you activated the app, type of item activated, number of keystrokes used to navigate, time spent navigating in milliseconds, total number of open windows |
Dismissed without activating | Number of keystrokes used to navigate, time spent navigating in milliseconds, total number of open windows |
Settings snapshot | Your current display settings (show clock, blink on activate, show navigation order), along with the version number of your Tabber installation. |
Trial Started | That you opened Tabber for the first time |
Trial Warning Shown | That your remaining trial activations reached the low-activation threshold |
Trial Expired | That your trial period has ended |
Purchase Link Clicked | That you clicked a purchase link, and which prompt triggered it |
Uninstall or Upgrade | The version number of your Tabber installation. |
Each event is tagged with an anonymous random ID (UUID) generated on first run and stored locally on your device. This ID is not linked to your name, email, or any other personal information. It exists only to distinguish one device's usage from another in aggregate statistics.
In addition to per-event data, the following device properties are sent alongside every analytics event and attributed to your anonymous device ID: Tabber version number, Windows operating system version, number of connected monitors, and whether your installation is a trial or licensed copy. None of these properties identify you personally.
IP Address and Geographic Data
To provide geographic analytics (country and region), Tabber retrieves your device's public IP address at startup using ipify.org, a third-party IP lookup service. The IP address is held in memory only for the duration of the session and is never written to disk or linked to your anonymous device ID.
The IP address is forwarded to Google Analytics solely to determine your geographic region. Google Analytics uses it to derive a country and region, then discards the raw IP address — it is not stored in analytics reports or raw data. Only the derived geographic region is retained.
By using Tabber with analytics enabled, you consent to this limited use of your IP address. You can disable analytics at any time in Tabber's Settings, which will stop all data collection including IP address retrieval.
Crash Reporting
If Tabber crashes, a crash report is automatically sent to Sentry. This report includes:
-
The error message and stack trace (code location of the crash)
-
Operating system version and Java runtime version
-
Tabber version number
-
Your anonymous device ID
Crash reports do not include window titles, screen content, file names, or any information about what you were doing in other applications.
Version & Integrity Check
Once per day, Tabber contacts spookyfish.com to verify your version is still supported. This request includes your Tabber version number. Like all internet connections, it also transmits your IP address to Spooky Group LLC's server, which is logged in standard server access logs and not used for any other purpose. This check is required for software integrity and cannot be disabled.
