Privacy
Your battery data stays on your Macs.
Last updated October 2, 2026
Who we are
BatteryBud is made by Climactic Infotech Private Limited, a company registered in India. We are responsible for the data that this page describes. For questions, write to [email protected].
What stays on your Mac
Battery levels, charging history and health are stored only on your Mac. If you turn on Other Macs, your Macs share them directly over your local network, encrypted with your sync code. None of it is sent to us.
What goes over the internet
- License checks go to Polar, which sells BatteryBud: your license key and the name of this Mac.
- Update checks download the update list from batterybud.app.
- Downloads of BatteryBud and its updates come from batterybud.app. We count them: the version, the date, and for an update the version it replaces. Nothing in the count identifies you.
- Anonymous usage data goes to batterybud.app, as listed below.
Anonymous usage data
It is on by default, and nothing is sent until you finish the welcome window. Turn it off at any time with “Share anonymous usage data” in Settings → General. It stops at once, and BatteryBud deletes what it hasn't sent and the random ID below.
Each report has a random ID made on your Mac (not linked to you or your license), the BatteryBud and macOS versions, and these events:
| Event | When | Details |
|---|---|---|
app.launch | Each time BatteryBud starts | License state: unlicensed, active, revoked or too new |
usage.daily | At most once a day | How many devices of each kind (Mac, iPhone, iPad, iPod touch, Vision Pro, Apple Watch, AirPods, Beats, keyboard, mouse, trackpad, other), how many are hidden, how many iPhones or iPads are waiting for setup, and how many other Macs are synced; how many widgets, pinned menu bar items and alert rules; whether sync, open at login and automatic update checks are on; the menu bar mode; the iPhone refresh interval; whether Bluetooth, notification and Local Network access are allowed; whether history can be saved; how often the menu bar popover and the main window were opened |
license.activated | A license is activated on this Mac | None |
license.renewed | An updates renewal key is added | None |
license.deactivated | This Mac is deactivated | None |
license.activationFailed, license.renewalFailed | A key is not accepted | Why, from a fixed list (for example: not a key, already active on another Mac, offline). Never the key. |
onboarding.finished | The welcome window is completed | None |
alert.fired | A battery alert is shown | Which kind of alert (low, charged, not seen or battery health). Never the device or the level. |
Never in usage data: license keys, email addresses, device or computer names, serial numbers or other device identifiers, Bluetooth addresses, your sync code, battery levels or history, file names, or anything you type.
Our server keeps your IP address in memory only, to limit abuse, and does not store it.
When you buy
Polar Software, Inc. sells BatteryBud as the merchant of record. Polar collects your name, email address, billing address and payment details, and its privacy policy applies to them. We never see your card number. From Polar we get your name, email address, country, order and license status, which we use to give you your license, support and refunds.
When you write to us
We keep your email and our answer for as long as it is necessary to help you, and we use them for nothing else.
This website
batterybud.app uses Google Analytics and Umami to count visits to its pages, and Polar to process purchases. This is separate from the app. Google Analytics sets cookies in your browser. Umami sets no cookies. For some visits, Umami also records how the page is used (clicks, scrolling and pointer movement) so that we can find problems with the pages. Text that you type into a field is not recorded. We keep these recordings for 30 days. After a purchase, the website records the amount and currency of the order for these two services, without your name or email address.
How long we keep data
- Anonymous usage data: until we no longer need it to improve BatteryBud. It cannot be linked to you, so we cannot find or delete the reports of one person.
- Purchase records: for as long as tax and accounting law requires.
- Support email: until your question is closed and a reasonable time after that.
Your rights
You can ask us for a copy of the personal data that we have about you, ask us to correct or delete it, or object to its use. Write to [email protected]. We do not sell personal data, and we do not use it for advertising.
Changes
When the app starts to send something new, we change this page first. The date at the top shows the last change.
