Battery Drain Insights Privacy
This policy covers the Battery Drain Insights app for Mac and this website.
Battery Drain Insights collects nothing about you. The app never connects to the internet. What it records about your battery is written only to your own Mac, is deleted automatically after 30 days, and you can erase all of it at any moment. Nothing is sold, nothing is shared, and there are no ads.

What does the app record, and where does it go?
To tell you what is draining your battery, Battery Drain Insights keeps a record while your Mac is on battery: which apps and background programs were running, how much work each one did, the battery level over time, and when you unplugged and plugged in. It also notes the condition of the battery, such as its capacity and cycle count.
That record is written to storage belonging to the app on your own Mac. It is not uploaded, not backed up to us, and not readable by us. We have no way to see it.
Records older than 30 days are deleted automatically. You can erase everything at once, at any time, with Clear battery history on the History tab. Erasing is real deletion, not hiding.
What is the battery diary, and what does the app do with it?
macOS keeps its own power log: when your Mac slept, when it woke and why, and how much charge it had. Battery Drain Insights calls it the battery diary. The app reads it only if you allow it, with one click, and it only reads. It uses the diary to show the last two weeks and the stretches with the lid closed. What it reads stays on your Mac with the app's other records, and you can stop the reading at any time in Settings.
Does the app connect to the internet?
No. Battery Drain Insights contains no networking code, and it does not hold the permission macOS requires before an app from the App Store may use the network. There is no Battery Drain Insights server, no account to create and no sign-in.
You get the app and its updates from the Mac App Store. That is Apple's App Store doing its work, with Apple's software, and it is the same for every app you get there. We never see your Apple Account or your name. Apple does not give them to us.
Is there analytics, crash reporting or anyone else's code?
No. The app is built only from Apple's own frameworks. There is no analytics software, no crash reporting service, no advertising software and no other company's code inside it. It also uses no AI service and sends nothing to one.
Do you sell or share my data?
No. Not to advertisers, not to data brokers, not to anyone, in any form. Since nothing ever reaches us, there is no store of data that could be sold.
What about notifications?
If you allow them, Battery Drain Insights tells you when something drains your battery. Those notifications are made on your Mac by the app itself. They do not pass through any server, ours or anyone else's.
What happens when I ask for help?
Nothing is sent without you pressing Send yourself. When you press Get Help, the app asks whether a diagnostics file may go along. If you say yes, it puts the app's log and a summary of what your Mac let the app read into one file. That file may contain the names of the apps and background programs that used your battery, and entries from your Mac's battery diary.
Then an email opens in your own mail program, addressed to us, with the file attached if you agreed. You can read it, remove the file, or close it without sending. If you send it, we use what it contains to answer you and to fix the problem, and for nothing else.
What does this website do?
This website loads no analytics and no tracking of any kind. The contact page is the one exception to loading nothing: it embeds a form from Tally so you can write to us, and that form receives what you type into it. The app contains no analytics and no other company's code either.
The site is hosted on Cloudflare Pages, which keeps ordinary server logs of requests in the way any web host does.
Children
Battery Drain Insights is a utility for your own Mac and is not directed at children. It collects nothing from anybody, of any age.
Changes to this policy
If this policy changes, the date at the top of this page changes with it. A change that would start collecting data would be described here in plain words, before the app that does it is released.
How to reach us
Write to us through the contact page, or press Get Help in the app's Settings. We answer questions about this policy the same way we answer everything else.
Battery Drain Insights is a Mac app for MacBook laptops (macOS 12 or later, Apple silicon and Intel) that shows what is draining the battery in plain words: which background programs and apps did the most work since you unplugged, what kept the Mac awake while its lid was closed, and how worn the battery is. It never connects to the internet. Nothing is collected, and there are no ads and no account.
