Privacy policy

Last updated: 2026-05-16

The short version

  • Your network traffic never leaves your Mac. DataCever does its monitoring and blocking entirely on-device.
  • We don't run servers that see what apps you use, what sites you visit, or how much data you use.
  • We collect anonymous usage and crash analytics (no personal info, no network traffic content) to fix bugs and prioritise features.
  • You can email support@datacever.com any time for privacy questions or data requests.

1. About us

DataCever is distributed via the Mac App Store. This policy covers the DataCever Mac app and the marketing website at datacever.com.

About this website: datacever.com uses Google Analytics 4 to measure aggregate visits and which pages people read. GA receives standard HTTP request signals (IP address, browser, OS, referring page); we don't configure custom events that contain personal information. Any modern tracker-blocker disables GA entirely. The rest of this policy is about the DataCever app, not the website.

2. What stays on your device

The following data is processed entirely on your Mac and is never sent anywhere

  • The list of apps installed on your device
  • Which apps you've allowed or blocked from the internet
  • Per-app data usage measurements
  • Per-app quotas you've configured
  • Any DNS, IP, or hostname information that DataCever observes while monitoring

If you uninstall DataCever, all of this data is removed with the app's containers and the network helper.

3. Anonymous analytics we collect

To find bugs faster and prioritise improvements, DataCever sends anonymous usage and crash events to a small number of well-known third-party analytics providers.

Specifically, these providers never receive:

  • The amount of data any app has used
  • The contents or destinations of any network traffic (DNS, IPs, hostnames)
  • Your email, IP address, name, or anything personally identifying

The events we do send are limited to: app launched, app version, macOS version, device model family, and interaction events such as opening the quota dialog or toggling an app's allowlist setting. When you block, allow, or set a quota on a specific app, the name of that app (e.g. "Safari", "Chrome") is included as a parameter on the event so we can see which apps people most commonly want to control. These events carry no user identifier; we look at them aggregated across all users, not per-user.

Opting out of analytics

A future DataCever update will surface an in-app toggle to disable analytics entirely. In the meantime, if you want to opt out, email support@datacever.com and we'll exclude your sessions from our analytics dashboards. Because the events we collect carry no user identifier, the opt-out is applied to your future sessions on a best-effort basis.

4. Changes to this policy

We may update this policy when we ship features that change what data is processed, or when we add or remove a third-party service. Whenever we change it, we'll bump the "Last updated" date at the top and (for material changes) mention it in the DataCever release notes.
