Cone Glaze · iOS
Effective 22 September 2026
Cone Glaze is a glaze book, cone chart and kiln log for hobby potters. This policy explains what happens to information inside the app. Contact details are at the end.
None. The app has no servers, doesn't send your content anywhere and contains no third-party SDKs for analytics, advertising, crash reporting or sign-in. In App Store terms the app is "Data Not Collected" and does not track you.
| Item | Where | Why |
|---|---|---|
| Your glaze recipes, firing schedules, kilns and firing log | App storage on the device | So your studio notebook is there next time you open the app |
| Test-tile photos you take or choose | App storage on the device | To show the tile next to its recipe and cone |
| Settings (theme, units, sound, haptics, reminders) | UserDefaults on the device | To remember your preferences |
This data is included in your own iCloud or computer backups if you have device backups turned on. That is handled by Apple under your Apple Account settings, not by us.
The camera is only used when you tap to photograph a fired test tile. The picture is saved inside the app on your device. Nothing is uploaded.
When you attach an existing photo, the app uses the system photo picker. Only the picture you pick is copied into the app. The app does not browse or read the rest of your library.
Cone Glaze uses local notifications scheduled on your device: when a firing segment reaches temperature, when a firing ends, when the kiln should be cool enough to unload and, if you switch it on, a weekly test-tile reminder. No push service is used and no device token leaves your device. You can turn notifications off in iOS Settings at any time.
We do not share, sell or rent any data because we don't receive any.
Use Studio → Settings → Erase everything to remove all recipes, firings, kilns and tiles, or delete the app to remove everything it stored.
The app is a general-audience hobby tool. It collects no personal information from anyone, including children under 13.
Because we hold no personal data about you, there's nothing for us to access, correct, export or delete on our side. Laws such as GDPR, UK GDPR, CCPA and similar still give you those rights, and you can contact us with any question.
If this policy changes, the new version will be posted on this page with a new effective date.
