Voltway does not collect your data.
Everything Voltway measures about your battery stays on your Mac. There is no Voltway account, no Voltway server, and no analytics SDK. We could not look at your battery history even if we wanted to.
Voltway is a Mac app. There is no iPhone, iPad or web version, and no companion app on any other platform — so everything below describes one program running on one Mac.
Voltway records information about your own battery so it can show you a timeline and trends. All of it is written to storage on your Mac and never leaves it.
Voltway Free keeps the last 7 days of charge history and discards anything older; Voltway Pro keeps all of it. Either way the file lives only on your Mac.
Voltway Pro is sold through Apple's In-App Purchase. Apple processes the payment; we never see your payment details, card number or billing address. Voltway checks your purchase entitlement directly with Apple on your Mac to decide whether Pro features are unlocked.
Voltway contains no advertising and no ad SDK.
The Voltway charge helper is a separate program you download and install yourself. It is not part of the Mac App Store app, and Voltway works without it. Only install it if you want Voltway to control charging.
It runs as a root background daemon. Once installed, macOS starts it as root at every boot and keeps it running whether or not Voltway is open. That is not incidental: the charge limit it sets lives in registers on your Mac's power controller which are cleared by a power cycle, so something has to be running at boot to put your limit back. The charge helper page lists exactly what the installer places on your Mac.
Networking. The helper talks to the Voltway app over your Mac's own loopback interface only (127.0.0.1, port 53845). That traffic never leaves your computer. The helper has no other networking, contacts no server, and sends nothing to us.
It writes a log. The helper keeps a plain-text log at /Library/Logs/Voltway/helper.log, owned by root and readable by anyone with administrator access to your Mac. It records what the helper did and why: your charge-limit settings, and the battery readings behind each decision — state of charge, whether the adapter is connected, whether the pack is charging, and pack temperature. It exists so a Mac that stopped charging can be diagnosed after the fact. It rotates at 512 KB and keeps three older copies, so it does not grow without bound. Nothing in it is transmitted anywhere; if you ever want us to see it, you have to send it to us yourself.
Because the helper's files sit outside the app's sandbox, they are not removed by deleting Voltway. See Removing your data.

Voltway 1.0 collects no data of any kind.
Voltway is a Mac utility, is not directed at children under 13 and does not knowingly collect information from them.
Because Voltway stores its data only on your Mac, you are in direct control of it. There is no server-side copy for us to delete and no request you need to send us. But dragging the app to the Trash does not delete everything, so here is exactly where it all is.
Your charge log and settings live in Voltway's App Sandbox container, which macOS deliberately leaves behind when you delete an app:
~/Library/Containers/com.mwsupplylimited.voltway/To remove it, delete Voltway, then delete that folder. In Finder, use Go › Go to Folder and paste the path above, or run rm -rf ~/Library/Containers/com.mwsupplylimited.voltway in Terminal. No administrator password is needed — it is your own folder.
If you installed the optional charge helper, its files are separate, root-owned, and not touched by deleting the app. Remove the helper first, which also restores normal charging:
sudo voltway-helper-uninstallThen, to delete its log and your saved charge limit:
sudo rm -rf /Library/Logs/Voltway "/Library/Application Support/Voltway"If you never installed the helper, none of these files exist on your Mac.
If this policy changes, the revised version will be posted on this page with a new date. Material changes will also be noted in the app's release notes.
