Usage data
Anonymous usage is an optional message that counts how Acira is used. It is a small message sent at most once a day. It has no web addresses, history, searches or accounts. You can read the exact message before and after you turn it on, and you can turn it off at any time.
Where the switch is
- During setup, the Privacy step shows Share anonymous usage with an explanation. In new setup the switch is already on when the step opens, and you can turn it off right there. What's sent opens the exact message. Acira can send the first message a few seconds after the step opens, so switching it off afterwards stops later messages but cannot recall one that was already sent.
- After setup, open Settings › Privacy › Anonymous usage. Open the group to see the switch, named Send anonymous usage counts.
Opening Settings never turns it on. A choice you saved earlier, on or off, is kept.
When you turn it off, Acira says so: Usage sharing is off. It saves your choice and deletes the local usage ID.
See exactly what is sent
- Open Settings › Privacy › Anonymous usage.
- On the row See what's sent, choose Show.
- Read the text under The exact message. It is the same object Acira would send, not a summary. While the switch is off, it shows an ID made only of zeros and says nothing is sent while this is off.
Choose Hide to close it.
What the message holds
At most one message per day (by UTC date). Acira sends the first one a few seconds after you turn the switch on, then checks about every six hours whether today's message has gone. It has a random ID, the date and coarse values from fixed lists. Counts are put in ranges and never exact. The groups are:
| Group | What it holds |
|---|---|
| How you set up Acira | Look: theme, finish, window view, tab layout, toolbar, animation speed and interface size. Interface language and the name of your search engine (never what you search). Protection: AI-free, ad blocking, phishing protection, and how many sites have protection off (never which). Link preview, ask before closing, tab sleep, and whether you changed any shortcut. Whether a proxy or a VPN is on, and the VPN app's name. Whether setup finished or was skipped, the browser you moved from, whether passwords were imported (yes or no) and Sign back in progress. |
| Which features you use | How often you used split view, Peek, Seamless, workspaces, tab groups, Rewind, tab sets, private and Tor tabs and windows, VPN, media controls, the command bar and the protection panel: 0, 1 to 2, 3 to 9 or 10 and more. |
| Ranges | Open tabs, windows, panes in a split view, workspaces, profiles and extensions, as ranges. |
| Your system | Acira version and channel, the operating system, processor type, language, and the date without the time. |
| A random ID | A random number made when you turned this on and deleted when you turn it off. |
Never sent: websites, searches, page titles, history, accounts, names or files. Your IP address is not part of the message. A server that receives any request can see the address it came from while it handles the request.
Ratings
When Anonymous usage is on, a second switch appears: Ask me now and then how features are working. It is on by default. It asks at most once a week, about features you use and no others, with stars and no typing: How do you like Split view?. A star answer holds the feature, your stars, the Acira version, the system and the date. It has no ID that links it to you. Choose Not now to skip a question.
Turn it off
- Open Settings › Privacy › Anonymous usage.
- Switch Send anonymous usage counts off.
Nothing is sent while it is off. Turning it off deletes the local random ID, the saved counts and the rating state. If you turn it on again, Acira makes a new ID, so the two periods cannot be linked.
When nothing is sent even if it is on
- If the build you run has no counting server switched on, Settings says Acira's counting server is not switched on in this version, so nothing can be sent even when this is on.
- If your default profile is set to use a manual proxy, no message is sent. Acira sends it once that profile follows your computer's connection again.
Limits
- This is not an account, and Acira has no sign-in or sync.
- Acira sends no crash reports. Update checks are separate. See Updates.
- For everything else Acira fetches in the background, see Privacy settings.
