Daily Scales collects nothing of its own.
No accounts, no analytics, no advertising, no tracking, no third-party services. There is no server of mine behind the app. Your practice history, your settings and your imported tunes live on your iPhone or iPad and nowhere else. Delete the app and they're gone with it.
The one thing the app talks to is Apple's App Store, to start the free trial, to make the purchase that unlocks the app and to check that purchase afterwards. Apple handles all of it. I never see your name, your email address or any payment details.
This website works the same way: no cookies, no analytics, no trackers.
On Android
On Android, the app talks to Google Play to start the free trial's purchase, to unlock the app and to check that purchase afterwards; Google handles it and I never see your name, email address or payment details. If you scan a QR code in the app, the scanner is Google's (part of Google Play services), and Google receives anonymous diagnostics from it: the device model and Android version, the app's version, a random identifier for that installation, and whether the scan worked. Google says it does not share these with anyone else. I never see them.
Android's own backup may copy your settings and practice history to your Google account, as it does for other apps; that copy is yours and Google's, not mine.
YouTube
Daily Scales has a YouTube channel, and I publish its videos with a small tool I wrote that uses YouTube API Services. This section is about that tool. Nothing about it touches the app or this website.
The tool runs on my own computer and signs in to the Daily Scales channel with my own Google account. It uploads the videos I have rendered, sets their thumbnails and adds them to playlists. That is all it does.
It has no users other than me. It does not collect, store or share anyone's data. The only thing it keeps is the sign-in token Google issues for my channel, in a file on my computer, so that I do not have to sign in again for every upload. Deleting that file ends its access, and nothing else remains to delete.
Because it uses YouTube API Services, the tool is bound by the YouTube Terms of Service and by Google's Privacy Policy. Access granted to it can be revoked at any time from the Google security settings page.
This site links to the channel but does not embed a player, so visiting this site makes no request to YouTube. Watching the channel itself is covered by YouTube's own terms and privacy policy, not by this page.
If any of that ever changes, this page will say so plainly before it does.
